Further, the master chip is stm321051c8t6.

Further, the ultrasonic distance measuring module includes the ultrasonic sensor for ranging, the temperature for thermometric Degree sensor and the correction module being corrected according to temperature to distance measurement result, the input terminal of the correction module is respectively with surpassing Sonic sensor is connected with temperature sensor, and the output terminal of the correction module is connected with comparator.

From the above description of the utility model, it can be seen, compared to the prior art, the utility model has the following advantages that：

1st, this product carries dustbin height detection and sends the function of warning message, and can be with long-range administrative center Wireless connection is carried out by way of narrowband, so as to fulfill long-range monitoring and real-time early warning.

2nd, the error-detecting of ultrasonic distance measuring module automatic temperature-adjusting and calibration function ensure under various real time temperature environment Detecting distance precision.

3rd, using the radio frequency chip of LORA long distance modems, for extra long distance spread spectrum communication, strong interference immunity, Current drain can be reduced to greatest extent, has apparent advantage in terms of antiblocking and selectivity using above-mentioned radio frequency chip, solved Traditional design of having determined scheme can not take into account distance, anti-interference and power problems simultaneously.

4th, product can be connected by radio frequency chip with administrative center, and periodically send reserve information to administrative center, work as prison When the dustbin of survey exceeds the limit value of height, product can automatic alert, administrative center is again to responsible person concerned Mobile phone send warning message, not only effectively increase work efficiency, but also reduce garbage disposal cost.

Specific embodiment

Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.

Reference Fig. 1, a kind of dustbin detection device based on narrow band communication, including：

Battery 1：For lithium battery or dry cell, regulator circuit is connected with, appraises and decides output voltage as 3.3V.

Using the radio frequency chip 2 (hereinafter referred to as radio frequency chip) of LORA long distance modems：Using SEMTECH companies SX127X systems class chip, for extra long distance spread spectrum communication, strong interference immunity can reduce current drain to greatest extent, profit There is apparent advantage in terms of antiblocking and selectivity with above-mentioned radio frequency chip 2, solving traditional design scheme can not be simultaneous simultaneously Care for distance, anti-interference and power problems.

Master chip 3：Using the stm321051c8t6 chips of ST Microelectronics, master chip 3 has data processing work( Can, it includes judging the comparator 31 of rubbish height in dustbin, for triggering radio frequency chip 2 by reserve information or report Trigger module 32 that alert information is sent in time and with the unique corresponding address code 33 of master chip 3.The comparator 31 with Trigger module 32 connects；The trigger module 32 is connected with radio frequency chip 2.According to address code 33, staff can be rapidly by inspection The data of survey are mapped with the location information of corresponding dustbin detection device.

For measuring the ultrasonic distance measuring module 4 of rubbish height：The ultrasonic distance measuring module 4 is included for the super of ranging Sonic sensor 41, the temperature sensor 42 for thermometric and the correction module that is corrected according to temperature to distance measurement result 43, the input terminal of the correction module 43 is connected respectively with ultrasonic sensor 41 and temperature sensor 42, the correction module 43 output terminal is connected with comparator 31.Ultrasonic sensor 41 is usually mounted to the top of dustbin, it can send multiple Then ultrasonic pulse detects echo-signal, after echo-signal is detected, temperature sensor 42 can be to the temperature in dustbin It measures, then correction module 43 is corrected distance measurement result according to current temperature, so as to obtain accurate measured value.
