the alarm device 5 is used for alarming when the current distance is smaller than a first distance threshold value.

The detector assembly 2 is arranged on a crane arm, and the detector assembly 2 is in communication connection with the upper computer 4 through the signal converter 3; in the ascending or horizontal moving process of the crane arm, the detection assembly detects an induced charge signal of the electrified high-voltage wire and transmits the detected induced charge signal to the signal converter 3; the signal converter 3 converts the induced charge signal into an electronic signal and then transmits the electronic signal to the upper computer 4; host computer 4 confirms the current distance of crane arm and electrified high-voltage line according to electronic signal to judge whether current distance is less than first distance threshold value, if current distance is less than first distance threshold value, host computer 4 reports to the police with regard to control alarm device 5 rather than communication connection, and then reminds driver's crane arm near with the distance of electrified high-voltage line, do not continue current operation, thereby play and avoid crane arm and electrified high-voltage line contact, driver's personal safety and equipment safety have been guaranteed.

It should be further explained that the detector assembly 2 can generate induced charge signals with different intensities according to the distance from the electric high-voltage line, the detector assembly 2 gradually moves to the electric high-voltage line from a distance, if the induced charge signals are intensified, the induced charge signals are converted into electronic signals capable of being recognized by the upper computer 4 through the signal converter 3, the current distance between the current crane arm and the electric high-voltage line is judged through the electronic signals, and when the current distance is smaller than a distance threshold value, the alarm device 5 is controlled to give an alarm.

It is particularly noted that the upper computer 4 may be a traveling computer, or may be a separately provided processor with calculation control capability, that is, a processor capable of determining the current distance between the crane arm and the live high-voltage line through an electronic signal, and determining whether the alarm device 5 needs to be controlled to alarm according to the current distance.

Further, the detector assembly 2 comprises at least a first detector 21, a second detector 22 and a third detector 23;

the first detector 21 is arranged at the head of the crane arm, the second detector 22 is arranged at the middle of the crane arm, and the third detector 23 is arranged at the bottom of the crane arm.

It should be noted that, because the length of the crane arm is very long, in order to avoid any crane arm contacting with the live high-voltage line, the first detector 21 is arranged at the head of the crane arm, the second detector 22 is arranged in the middle of the crane arm, and the third detector 23 is arranged at the bottom of the crane arm, so that the induced charge signal of the live high-voltage line can be detected in real time through the arranged first detector 21, the second detector 22 and the third detector 23, and further, when the crane arm is close to the live high-voltage line, an alarm can be given out to remind a driver, so that the crane arm is prevented from contacting with the live high-voltage line, and the personal safety and the equipment safety of the driver are effectively guaranteed.

It should also be noted that the probe assembly 2 is comprised of a plurality of probes, which are axially disposed along the crane arm.

Specifically, the alarm device 5 includes: a light alarm 51 for performing a light alarm and/or an audible alarm 52 for performing an audible alarm.

It should be noted that, by setting the light alarm 51 and/or the sound alarm 52, the controller may send an alarm instruction to the light alarm 51, and after the light alarm 51 receives the alarm instruction, the light flashes in a preset flashing manner to prompt the driver. And the controller sends alarm refrigeration to the sound alarm, and after the sound alarm 52 receives the alarm instruction, the sound alarm 52 sends out alarm according to preset recorded sound or sends out harsh sound to prompt the driver.

It should be further noted that the light alarm 51 may flash according to the distance between the crane arm and the live high-voltage line when performing the alarm, for example, when the crane arm is far away from the live high-voltage line, the light alarm 51 has a lower flashing frequency, and when the crane arm is close to the live high-voltage line, the light alarm 51 has a higher flashing frequency. When the alarm is performed, the audible alarm 52 can also emit the dripping sound with different frequencies according to the distance between the crane arm and the charged high-voltage line, for example, when the distance between the crane arm and the charged high-voltage line is longer, the dripping sound frequency of the audible alarm 52 is lower, and when the distance between the crane arm and the charged high-voltage line is shorter, the dripping sound frequency emitted by the audible alarm 52 is higher.

It should be further noted that the range of the image collected by each camera 7 is limited, a plurality of cameras 7 are arranged around the transformer substation crane, the images collected by the cameras 7 are transmitted to the upper computer, the upper computer analyzes and synthesizes the images, and transmits the images to the display device 6 for display, and the display device 6 at the moment can display the image on one side of the transformer substation crane or can display all the images around the whole transformer substation crane.

Further, the transformer substation's crane prevents mistake and bumps system still includes: a power supply 8;

the power supply 8 is used for supplying electric energy to the upper computer 4.

It should be noted that, the power supply 8 for supplying electric energy to the upper computer 4 is arranged to ensure that the upper computer 4 can normally work, so as to avoid the situation that the upper computer 4 cannot normally work due to external factors, and further cause safety accidents due to the fact that a transformer substation crane is in contact with a live high-voltage line.

Based on the above disclosed transformer substation crane anti-false-collision system, referring to fig. 3, the embodiment of the application further discloses a transformer substation crane anti-false-collision method, which is suitable for a transformer substation crane anti-false-collision system comprising a detector assembly, a signal converter, an upper computer and alarm equipment, and the transformer substation crane anti-false-collision method at least comprises the following steps:

s201, the detector component sends the induced charge signal of the detected high-voltage line to a signal converter;

s202, converting the induction charge signal into an electronic signal by a signal converter;

s203, the upper computer determines the current distance between the crane arm and the live high-voltage line based on the electronic signal;

s204, the upper computer judges whether the current distance is smaller than a first distance threshold, if so, the step S205 is executed, and if not, the step S201 is continuously executed;

s205, the upper computer sends an alarm instruction to alarm equipment;

and S206, the alarm equipment executes alarm based on the alarm instruction.

It should be noted that, because the alarm device may be an audio alarm device, a light alarm device, or an alarm device that is an audio alarm device plus a light alarm device, when the alarm device is an audio alarm device, the audio alarm device executes an audio alarm based on the alarm instruction audio alarm device; when the alarm equipment is a light alarm, the light alarm executes alarm based on the alarm instruction; if the alarm device is a sound alarm device and a light alarm device, the light alarm device executes light alarm and the sound alarm executes sound alarm.

According to the embodiment of the application, the induced charge signal of the detected high-voltage line is sent to the signal converter through the detector; then the signal converter converts the induction charge signal into an electronic signal; the upper computer determines the current distance between the crane arm and the electrified high-voltage line based on the electronic signal; the upper computer judges whether the current distance is smaller than a first distance threshold value or not, and sends an alarm instruction to the alarm device if the current distance is smaller than the first distance threshold value; and finally, the alarm equipment executes alarm based on the alarm instruction. According to the transformer substation crane anti-collision method, in the ascending or horizontal moving process of the crane arm, the detection assembly detects the induced charge signal of the live high-voltage wire and transmits the detected induced charge signal to the signal converter; the signal converter converts the induction charge signal into an electronic signal and then transmits the electronic signal to an upper computer; the host computer confirms the current distance of crane arm and electrified high-voltage line according to electronic signal to judge whether current distance is less than first distance threshold value, if current distance is less than first distance threshold value, the host computer is just controlled rather than communication connection's alarm device and is reported to the police, and then reminds driver's crane arm near with the distance of electrified high-voltage line, do not continue current operation, thereby play and avoid crane arm and electrified high-voltage line contact, driver's personal safety and equipment safety have been guaranteed.

It should be noted that, after the alarm device performs the alarm according to the alarm command, the driver does not make a corresponding response to the substation crane in time, i.e. brake or retreat, and therefore, the driver may operate the substation crane to contact the live high-voltage line, and in order to completely avoid the contact between the substation crane and the live high-voltage line, the following steps should be performed with reference to fig. 4 after step S206 is performed, i.e. after the alarm device performs the alarm based on the alarm command:

s301, the upper computer judges whether the current distance is smaller than a second distance threshold value, and if the current distance is smaller than the second distance threshold value, the step S302 is executed; if the current distance is not smaller than the second distance threshold, step S301 is continuously executed.

And S302, the upper computer sends a braking instruction to the transformer substation crane.

It should be noted that, a braking instruction is sent to the transformer substation crane through the upper computer, so that the transformer substation crane executes braking after receiving the braking instruction, and then the transformer substation crane is prevented from contacting with the live high-voltage line, and personal safety and equipment safety of a driver are ensured.

Further, referring to fig. 5, the method for preventing the crane of the transformer substation from colliding further includes:

s402, the upper computer sends the image obtained after the image processing to a display device;

and S403, displaying the image by the display device.

It should be noted that, because human sense organs cannot sense the existence of electricity under a non-contact condition, when a driver sits in a cab to operate a crane arm, the distance between the crane arm and a live high-voltage line cannot be accurately observed, so that images around a transformer substation crane and a transformer substation crane are obtained in real time through a plurality of cameras and are sent to an upper computer, and then the upper computer sends the images obtained after image processing to a display device; and finally, the images are displayed through the display equipment, so that a driver can accurately distinguish the distance between the crane arm and the electrified high-voltage wire by observing the images displayed by the display equipment, and safety accidents caused by the contact of the crane arm and the electrified high-voltage wire are effectively avoided.

Further, the upper computer stores the image.

The upper computer stores the images, so that the standard operation can be conveniently learned later, and the safe operation of a driver is improved.
