Technical Field

The invention relates to the technical field of electronic information, in particular to an ultra-low power consumption wireless toilet paper volume detector based on NB-IOT.

Background

At present, most of toilet paper used in public toilets and families is placed in a toilet paper barrel and is provided for people to use, but the toilet paper barrel is sealed, so that the embarrassment and inconvenience are brought when the paper is used up easily when the paper is needed. In order to avoid the problem, a large amount of manpower is often needed to be used for replacing the toilet paper at regular time in public places, and the condition that no toilet paper exists occasionally can also occur, so that a great number of problems are brought to management and use.

The optical detection system used by some products in the current market can not detect induction accurately, has large power consumption and short working time, and needs to replace batteries frequently; other similar products are used for self-generating electricity, the cost is high, the generating set is easy to damage, the networking is complex, and the generating set needs to be installed by professionals and is not suitable for home users.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides an NB-IOT-based ultra-low power consumption wireless toilet paper volume detector. The problems of high product power consumption, low accuracy, complex installation and use and the like in the prior art can be solved.

The technical scheme adopted by the invention is as follows: an ultra-low power consumption wireless toilet paper volume detector based on NB-IOT comprises a detection sensor, a microprocessor, an NB-IOT communication module, an operator network module and a cloud computing center. The microprocessor is respectively connected with the detection sensor and the NB-IOT communication module, and the NB-IOT communication module transmits data to the cloud computing center through the operator network module.

The detection sensor comprises a stress sensor and an infrared high-precision distance measurement sensor.

And after the microprocessor performs node calculation processing on the data acquired by the detection sensor, the data are transmitted to the cloud computing center through the NB-IOT communication module. And the cloud computing center compares the obtained data with the previously sent data, calculates the accuracy of the current sensing data, and sends a feedback instruction to the microprocessor.

The toilet paper quantity detector also comprises a sound and light alarm module, and the sound and light alarm module is judged whether to be triggered or not through the feedback instruction obtained by the microprocessor. Three instructions are divided: firstly, the paper quantity is sufficient, the microprocessor enters a dormant state through the control NB-IOT module and the detection sensor, and waits for the toilet people to take paper to trigger new detection.

Secondly, the usable amount of toilet paper is less than 5%, the microprocessor triggers the sound and light alarm module, the toilet paper barrel alarm device can give an alarm for 1 time every 15 seconds, the indicator light flickers for 2 times, and the buzzer gives an alarm for 2 times.

And thirdly, no toilet paper is available, the toilet paper tube alarm device can give an alarm 1 time every 2 seconds, the indicator lamp flickers 1 time, and the buzzer gives an alarm 1 time. When the alarm time exceeds 3 minutes, no person changes the paper, the system enters a dormant state, and the staff is waited to change the paper.

Compared with the prior art, the invention has the beneficial effects that: by using the double sensors for detection, the accuracy rate can reach 99 percent; the microprocessor is used for node calculation, so that the intelligence is improved; the dual sensors and the microprocessor have the characteristic of ultra-low power consumption, and the NB-IOT communication technology reduces the power consumption of communication, does not need to frequently replace batteries and saves electric power. By using the operator network, the network has simple structure and simple and convenient installation, the data viewing is not limited by the geographical position, and the method can also be widely applied to family users.

Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.

The embodiment provides an ultra-low power consumption wireless toilet paper volume detector based on NB-IOT. As shown in fig. 1, the system comprises a detection sensor 11, a microprocessor 12, an NB-IOT communication module 13, an operator network module 14, and a cloud computing center 15. The microprocessor 12 is respectively connected with the detection sensor 11 and the NB-IOT communication module 13, and the NB-IOT communication module 13 transmits data to the cloud computing center 15 through the operator network module 14.

The detection sensor 11 includes a stress sensor and an infrared high-precision distance measurement sensor.

After the microprocessor 12 performs node calculation processing on the data acquired by the detection sensor 11, the NB-IOT communication module 13 transmits the data to the cloud computing center 15 through the operator network module 14. The cloud computing center 15 compares the acquired data with the previously transmitted data, calculates the accuracy of the current sensing data, and transmits a feedback instruction to the microprocessor 12.

The toilet paper quantity detector also comprises an audible and visual alarm module 16, and whether the audible and visual alarm module 16 is triggered is judged by feedback instructions obtained by the microprocessor 12. Three instructions are divided: firstly, the paper quantity is sufficient, the microprocessor 12 enters a dormant state by controlling the NB-IOT module 13 and the detection sensor 11, and waits for the toilet people to take paper to trigger new detection.

Secondly, the usable amount of the toilet paper is lower than 5 percent, the microprocessor 12 triggers the sound and light alarm module 16, the toilet paper tube alarm device alarms 1 time every 15 seconds, the indicator light flickers 2 times, and the buzzer alarms 2 times.

And thirdly, no toilet paper is available, the microprocessor 12 triggers the sound and light alarm module 16, the toilet paper tube alarm device can give an alarm 1 time every 2 seconds, the indicator light flickers 1 time, and the buzzer gives an alarm 1 time. When the alarm time exceeds 3 minutes, no person changes the paper, the system enters a dormant state, and the staff is waited to change the paper. When new tissues are put into the toilet paper tube again, the stress sensor and the infrared sensor in the detection sensor 11 work simultaneously, collected data are subjected to primary calculation through the microprocessor 12 and then are sent to the cloud computing center 15, the mass and the density of a newly-loaded paper core are computed, new data and a measurement formula are computed, and an instruction is fed back to the toilet paper tube again.

If the toilet paper tube receives a standby instruction, the toilet paper tube detection sensor 11 and the NB-IOT communication module 13 enter a dormant state; if a proofreading instruction is received, the indicator light flickers, and the condition that toilet paper is not normally put in, such as an empty space or a paper tube is blocked, generally occurs.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
