Technical Field

The present invention relates to the field of detection technologies, and in particular, to a detection method, an apparatus, a detection device, and a storage medium.

Background

With the development of technology, it is becoming more and more popular to detect abnormal situations occurring in life by using active detection signals (such as infrared rays, laser, ultrasonic waves, etc.). The working mode of detecting by using the active detection signal is that the detection equipment sets a fixed signal detection period emitted by the detection signal; and a receiving device of the detection equipment synchronously implements signal acquisition according to a fixed signal detection period transmitted by the detection signal. When a blocking object appears in the detection area and a receiving device of the detection equipment cannot receive a preset signal, an alarm signal is sent out to remind a user.

The inventor finds that: the signal detection period of the detection signal emission of the current detection equipment is fixed, if the period is set to be longer, the energy consumption can be saved, but because the signal detection period is long, the time interval between two adjacent detection signals is long. For example, if the adjacent detection signals happen to be blocked by a floating object (such as a leaf), the detection device may consider that there is a target object (such as an intruder), and thus a false alarm signal is sent out. When the signal detection period of the detection signal is set to be short, although the detection accuracy can be improved and the occurrence of false alarm/false alarm can be avoided, the detection at a short time interval for a long time (i.e., long-time high-density detection) increases energy consumption and accelerates the aging of devices.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

the detection method provided by the invention can be applied to the application environment shown in FIG. 1. Wherein the probing apparatus comprises a transmitting end 102 and a receiving end 104. The transmitting end 102 may establish a communication connection with the receiving end 104 in a wired or wireless manner, and the transmitting end 102 may also send a probe signal to the receiving end 104.

Specifically, the signal detection period of the detection device is: the detection device sends out detection signals for a plurality of times within the trigger response time. The relationship between the trigger response time and the signal detection period is: for example, when the trigger response time is 20 ms, if the first signal detection period is set to be N ═ 2 (i.e., there are 2 first signal detection periods in one trigger response time), each first signal detection period is 10 ms, i.e., the probe device sends out 2 probe signals within 20 ms, and the interval time is 10 ms. Similarly, when the trigger response time is 20 ms, the second signal detection period may be set to N-10 (i.e. there are 10 second signal detection periods in one trigger response time), and each second signal detection period is 2 ms, i.e. the probing apparatus sends out 10 probing signals within 20 ms, and the interval time is 2 ms.

As shown in fig. 1, the detecting device detects in the initial state in the first signal detection period with a longer interval time (for example, 2 signal detection periods within one trigger response time): the transmitting terminal 102 transmits a detection signal, and the receiving terminal 104 receives the detection signal transmitted by the transmitting terminal 102, so as to detect a detection area and determine whether a target object (such as an intruder and an out-of-range vehicle in a security scene) exists. The receiving end 104 may be configured with a controller 1 for detecting a receiving state of the probe signal received by the receiving end 104, and may also send a related instruction to the transmitting end 102 through the communication connection established in the wired or wireless manner, so as to instruct the controller 2 configured in the transmitting end 102 to switch a signal detection period. It will be understood by those skilled in the art that the probing apparatus can also be configured with a controller to detect the receiving status of the probing signal at the receiving end 104 and control the transmitting end 102 to switch the signal detection period. The controller may also be provided independently of the transmitting end 102 and the receiving end 104. The number and location of the controllers configured in the detection device do not constitute a limitation on the detection method of the present invention.

when the controller 1 detects that the probe signal transmitted by the transmitting terminal 102 is not received by the receiving terminal 104, the controller 2 is notified in a wired or wireless manner to shorten the interval time for the transmitting terminal 102 to send the probe signal, and the first signal detection period with a longer interval time is switched to the second signal detection period with a shorter interval time (for example, 2 signal detection periods within one trigger response time are switched to 10 signal detection periods). At this time, the detection device detects in the second signal detection period, and the controller 1 detects the receiving state of the detection signal of the receiving end 104, and determines whether there is a target object (e.g., an intruder, an out-of-range vehicle, etc. in a security scene) in the detection area according to the receiving state, so as to improve the detection accuracy. The type of the detection signal may be infrared, ultrasonic, laser, etc. The receiving state comprises a state that the detection signal is not received by the receiving end and a state that the detection signal is received by the receiving end; the state in which the detection signal is not received by the receiving end is related to the application requirement definition that the target object blocks the detection signal, for example, when the detection signal is infrared and is indoors, the state in which the detection signal is not received by the receiving end is defined as: the target object continuously blocks 75% of energy of the detection signal transmitted by the transmitting end to reach trigger response time; when the detection signal is infrared and is outdoors, the state that the detection signal is not received by the receiving end is defined as: the target object completely blocks the detection signal transmitted by the transmitting terminal, and the trigger response time is reached.

In one embodiment, as shown in fig. 2, a sounding method is provided, in which the method can be implemented based on the transmitting end 102 and the receiving end 104 shown in fig. 1, and the specific steps of the method can be performed by the controller 1 configured in the receiving end 104 and the controller 2 configured in the transmitting end 102, and the method includes the following steps:

step S202, acquiring a receiving state of a probe signal sent by the probe device in a first signal detection period.

wherein the probing apparatus includes a transmitting end 102 and a receiving end 104. The signal detection period of the detection device is as follows: the detection device sends out a plurality of detection signals within the trigger response time, and the interval time between two adjacent detection signals is shortened. The relationship between the signal detection period and the trigger response time is: for example, when the trigger response time is 20 ms and the first signal detection period N is 2, the signal detection period is 10 ms, that is, the transmitting end 102 sends out 2 probing signals within 20 ms, and the intervals are 10 ms each.

specifically, when the probing apparatus performs probing in the first signal detection period, the controller 1 obtains the receiving state of the probing signal of the receiving end 104 in real time for the probing signal transmitted by the transmitting end 102 in the first signal detection period. The first signal detection period may be set according to actual conditions.

Step S204, when detecting that the receiving state of the detection signal is not received by the receiving end, switching the first signal detection period into a second signal detection period; the second signal detection period is shorter than the first signal detection period.

Specifically, in the process that the transmitting terminal 102 transmits the probe signal in the first signal detection period, the controller 1 obtains the receiving state of the probe signal of the receiving terminal 104. When the receiving end 104 does not receive the probe signal, for example, when the receiving end 104 does not effectively receive the probe signal, the controller 1 notifies the controller 2 disposed in the transmitting end 102 to shorten the interval time for transmitting the probe signal, and switches the first signal detection period with longer interval time to the second signal detection period with shorter interval time.

Step S206, determining whether there is a target object in the detection area of the detection device according to the reception state of the detection signal emitted in the second signal detection period.

The target object can be an intruder, a moving object (such as an out-of-range vehicle), a static object (an object left in a detection area) and the like in a security scene; other objects, such as small animals, flying objects (e.g., leaves), etc., are generally defined as non-target objects according to application requirements.

Specifically, for the probe signal transmitted by the transmitting terminal 102 in the second signal detection period, the controller 1 resynchronizes the receiving state of the probe signal by the receiving terminal 104 to determine whether there is a target object in the probing area of the probing apparatus.

In the above detection method, the controller 1 detects the receiving state of the detection signal, and when the receiving state is not received by the receiving end, the controller 1 notifies the controller 2 to switch the first signal detection period with a longer interval time to the second signal detection period with a shorter interval time. By synchronously detecting the receiving state of the detection signal, the detection equipment can receive the detection signal at the receiving end when the detection signal in the detection area is not blocked, and the detection is carried out by adopting a signal detection period with longer interval time, so that the energy consumption is avoided; when the detection signal of the detection area is blocked by the target object entering the detection area, namely the receiving end does not receive the detection signal, the signal detection period with shorter interval time is adopted for detection, so that the detection precision is improved, and the detection equipment can take energy consumption and detection precision into consideration.

In one embodiment, the step of determining whether there is a target object in the detection area of the detection device based on the reception state of the detection signal emitted in the second signal detection period includes: and when the number of times that the receiving state of the detection signal sent in the at least one trigger response time is the state not received by the receiving end reaches a set value in the second signal detection period, determining that a target object exists in the detection area of the detection equipment.

The second signal detection period may be a multiple of the first signal detection period, and accordingly, the number of times that the transmitting terminal transmits the probe signal in the second signal detection period is a multiple of the number of times that the transmitting terminal transmits the probe signal in the first signal detection period, for example, under the condition that the trigger response time of the probe device is 20 milliseconds, the first signal detection period is 10 milliseconds, and at this time, the number of times that the transmitting terminal transmits the probe signal is 2 times; when the first signal detection period is 5 times of the second signal detection period, the second signal detection period is 2 milliseconds, the number of times of the emission of the detection signal by the emission end is 10 times, and the number of times of the emission of the detection signal by the emission end in the signal detection period of 2 milliseconds is 5 times of the number of times of the emission of the detection signal in the signal detection period of 10 milliseconds. The set value may be the number of times the transmitting end transmits the probe signal within one trigger response time. To those skilled in the art, it should be understood that: the detection times are increased, the detection result is more approximate to the equivalent expression of the trigger state within a time, in the practical situation, due to the characteristic of product sampling detection, the controller does not have the continuous detection capability within the time period, but the controller can adopt multiple times of sampling with shorter interval time to carry out intensive detection on the trigger state within the time period, and whether the receiving end continuously receives the detection signal is determined.

Specifically, for the probe signal transmitted by the transmitting end in the second signal detection period, the controller 1 acquires the receiving state of the probe signal of the receiving end. When the number of times that the receiving end does not receive the detection signal transmitted by the corresponding transmitting end reaches a set value within at least one trigger response time in the second signal detection period, the controller 1 confirms that the target object is in the detection area. For example, when the trigger response time is 20 ms and the second signal detection period is 2 ms, the set value is 10 times, that is, the transmitting end transmits 10 detection signals; if the detection signals are not blocked within 20 milliseconds, the receiving end correspondingly receives the detection signals for 10 times; when the probe signal is blocked by the target object, the receiving end does not receive the probe signal 10 times because the target object is limited by its fastest moving speed and cannot pass within 20 ms shorter than the trigger response time. It is understood that the small animal, fallen leaves, in the running state are much smaller than the human/move faster than the human due to their size, and the time that the small animal, fallen leaves, blocks the detection signal is shorter than the trigger response time by 20 ms.

In the above embodiment, the controller 1 may determine the target object in the detection area more accurately by determining the number of times that the receiving state of the detection signal sent within the at least one trigger response time is the state that is not received by the receiving end, so as to avoid false alarm.

In one embodiment, the detection device may issue an alarm signal if it is determined that there is a target object in the detection area. The alarm signal may be sent by the controller 1 of the receiving end 104, and triggers the security alarm device to ring on the spot on duty, so as to prompt security personnel on duty to check and dispose in due course.

In one embodiment, the step of determining whether there is a target object in the detection area of the detection device based on the reception state of the detection signal emitted in the second signal detection period includes: and when the frequency that the receiving state of the sent detection signal is the state which is not received by the receiving end does not reach a set value in the trigger response time under the second signal detection period, determining that no target object exists in the detection area of the detection equipment.

specifically, for the probe signal transmitted in the second signal detection period, the controller 1 acquires the reception state of the probe signal at the receiving end. When the number of times that the receiving end does not receive the state of the detection signal transmitted by the corresponding transmitting end does not reach the set value within the trigger response time, the controller 1 confirms that there is no target object in the detection area of the detection device. For example, under the condition that the trigger response time is 100 milliseconds, if the set value is 20 times, the transmitting end transmits the probing signal 20 times, and the receiving end does not receive the probing signal less than 20 times, at this time, the controller 1 confirms that there is no target object in the probing area.

In one embodiment, if the number of times of the state that is not received by the receiving end is not zero and does not reach the set value, it is determined that the detection area has the interfering object.

specifically, when the number of times that the receiving end does not receive the detection signal is not zero and does not reach the set value, the controller 1 determines that there is an interfering object in the detection area. For example, in the trigger response time, if the set value is 20 times, that is, the transmitting end transmits 20 times of the probe signals, if the receiving end does not receive the probe signals for only 3 times, at this time, the number of times of the state that is not received by the receiving end is not zero, and does not reach 20 times, the controller 1 determines that there is an interfering object in the detection area.

In another embodiment, when the receiving end intermittently does not receive the probe signal within a trigger response time in the second signal detection period, the controller 1 confirms that there is an interfering object in the detection area.

For example, when a transmitting end transmits a sounding signal 10 times in a trigger response time, if the sounding signal is not blocked, the corresponding receiving end receives the sounding signal 10 times. When the detection signal is blocked intermittently, the receiving end receives the detection signal intermittently for 8 times, that is, receives the detection signal intermittently for 2 times, for example, receives the detection signal once in the 4 th and 8 th signal detection periods, at this time, the controller 1 determines that there is an interfering object in the detection area, for example, the plants near the detection area are blown and shaken by wind, and form dynamic blocking to the detection area, but because the plant branches and leaves are evacuated, the 4 th detection signal and the 8 th detection signal can pass through, so that the receiving end receives the 4 th detection signal and the 8 th detection signal.

In another embodiment, if the ordering of the states not received by the receiving end is not continuous, it is determined that the detection region has an interfering object.

Specifically, when the sequencing of the state in which the probe signal is not received by the receiving end is discontinuous, the controller 1 determines that there is an interfering object within the detection area, that is, when the receiving end does not receive the probe signal discontinuously, the controller 1 determines that there is an interfering object within the detection area. For example, when the setting value is 10 times, that is, the transmitting end transmits the sounding signal 10 times within a trigger response time, the receiving end does not receive the sounding signal 1 st time, 3 rd time, 4 th time, 6 th time, 7 th time, 8 th time and 9 th time within the trigger response time, at this time, the receiving end does not receive the sounding signal 7 times discontinuously, that is, the sequencing of the state where the sounding signal is not received by the receiving end is discontinuous, at this time, the controller 1 determines that there is an interfering object in the detection area.

In another embodiment, if the sequencing of the state not received by the receiving end is discontinuous and the number of times not received by the receiving end does not reach the set value, it is determined that the detection area has the interfering object.

Specifically, when the order of the state in which the probe signal is not received by the receiving end is discontinuous and the number of times of non-reception by the receiving end does not reach the set value, the controller 1 determines that there is an interfering object in the detection area, that is, when the receiving end intermittently does not receive the probe signal and the number of times of non-reception by the receiving end does not reach the set value, the controller 1 determines that there is an interfering object in the detection area. For example, when the set value is 10 times, that is, the transmitting end transmits the sounding signal 10 times within a trigger response time, the receiving end does not receive the sounding signal 1 st time, 3 rd time and 4 th time within the trigger response time, at this time, the receiving end intermittently receives no sounding signal 3 times, that is, the sequencing of the states of the sounding signal not received by the receiving end is discontinuous and the number of times is smaller than the set value, at this time, the controller 1 determines that there is an interfering object in the detection area.

In another embodiment, if there is an interfering object in the detection area, the detection device may issue a prompt signal that there is an interfering object in the detection area to remind security personnel to verify in time and to dispose of it as appropriate. The above-mentioned prompt signal may be issued by the controller 1 of the receiving end 104 of the detection device.

In the above embodiment, when the controller 1 determines that the detection area has no target object, the detection device does not send out an alarm signal, thereby avoiding false alarm; further, when the detection device determines that the interference object exists, the detection device sends out a prompt signal to remind security personnel to check in time and dispose of the interference object as appropriate.

In one embodiment, if the detection device operates in the second signal detection period and a trigger response time is reached and it is determined that neither the target object nor the interfering object is present in the detection area, the detection device switches to the first signal detection period to perform the detection operation. Wherein, when the controller 1 detects: when the receiving end receives the detection signal of the set value (namely the number of times of the detection signal transmitted by the transmitting end) in a trigger response time, the target object and the interference object are determined to be absent in the detection area.

Specifically, when the receiving end receives all the probing signals transmitted by the transmitting end within the trigger response time, that is, the number of times that the receiving end does not receive the probing signals is zero, the controller 1 notifies the controller 2 to switch the second signal detection period of the transmitting end to the first signal detection period, so as to increase the interval time for the transmitting end 102 to transmit the probing signals, and reduce energy consumption.

In order to better understand the above method, referring to fig. 3, an application example of the detection method of the present invention is described in detail below, and the specific flow is as follows:

Step S302, the transmitting terminal transmits the detection signal in a signal detection period with a longer interval time, and the receiving terminal synchronously receives the detection signal transmitted by the transmitting terminal.

In step S304, the controller 1 acquires the reception state of the probe signal at the receiving end, and proceeds to step S306.

Step S306, the controller 1 determines whether the receiving state of the detection signal satisfies the condition of the switching signal detection period, and if the controller 1 determines that the receiving state of the detection signal does not satisfy the condition of the switching signal detection period, the step S304 is returned to; if the controller 1 determines that the receiving state of the probe signal satisfies the condition of switching the signal detection period, if the controller 1 determines that the receiving end does not receive the probe signal, the process goes to step S308.

In step S308, the controller 1 notifies the controller 2 to switch the signal detection period of the longer interval time to the signal detection period of the shorter interval time, and the process proceeds to step S310.

step S310, the transmitting terminal transmits the detection signal in a signal detection period with a short interval time, and the receiving terminal synchronously receives the detection signal transmitted by the transmitting terminal.

In step S312, the controller 1 determines whether the detection time reaches a trigger response time. If a trigger response time is not reached, returning to step S310; if the probe time reaches a trigger response time, the process proceeds to step S314.

Step S314, the controller 1 determines whether the alarm condition is satisfied, and if the controller 1 determines the receiving state of the detection signal at the receiving end, determines whether the receiving state satisfies the alarm condition; if the receiving state of the receiving end does not satisfy the alarm condition, for example, the receiving state of the detection signal is all received by the receiving end, the controller 1 informs the controller 2 to switch the signal detection period with shorter interval time to the signal detection period with longer interval time, then step S302 is entered; if the receiving status of the receiving end meets the alarm condition, for example, the number of times that the receiving end continuously receives no detection signal reaches the set value, step S316 is entered.

And step S316, sending an alarm signal to finish an alarm working procedure.

It should be noted that, for the sake of simplicity, the foregoing method embodiments are described as a series of acts or combinations, but those skilled in the art should understand that the present invention is not limited by the described order of acts, as some steps may be performed in other orders or simultaneously according to the present invention.
