In one embodiment of the invention, the intelligent metering box comprises a tilt sensor; and the inclination sensing signal output end of the inclination sensor is connected with the inclination sensing signal input end of the MCU controller.
The intelligent metering box comprises an inclination sensor, wherein the inclination sensor is used for monitoring the inclination angle of the intelligent metering box in real time and transmitting the inclination angle information to the MCU controller; and comparing the inclination angle acquired by the inclination sensor with a preset inclination angle threshold value by the MCU controller, judging that the current intelligent metering box is in a dangerous environment when the inclination angle acquired by the inclination sensor exceeds the preset inclination angle threshold value, and sending alarm information to the main station. The inclination angle threshold setting process of the MCU controller comprises the following steps:
the MCU controller monitors the use time length of the intelligent metering box in real time, and adjusts the inclination angle threshold value at the end time of the use period when the use time length of the intelligent metering box passes through one use period; specific:
s1, the MCU monitors the use time of the intelligent metering box in real time;
s2, the MCU controller calls the original weight information of the intelligent metering box into a memory at the end time of a use period; wherein the value range of the service period is 1-3 years;
S3, sending an intelligent metering box weight detection instruction to the main station, and receiving weight information of the current intelligent metering box fed back by a maintainer terminal in real time;
S4, setting a threshold adjustment coefficient by using the use time length of the monitoring intelligent metering box and the weight information of the current intelligent metering box; wherein the threshold adjustment coefficient is obtained by the following formula:
Wherein, lambda threshold adjustment coefficient; p n represents the theoretical usage wear rate corresponding to the intelligent metering box after the nth usage period; m n represents the actual weight of the intelligent batch meter after the nth use period; m 0 represents the original weight of the intelligent metering box; b represents a shell quality information matrix of the intelligent metering box; e 01 represents the elastic modulus of the intelligent metering box shell; r represents the number of faces of the intelligent metering box (e.g., r=6 when the intelligent metering box is a rectangular cabinet body); h i represents the rate of transverse deformation that has occurred on the i-th bin surface; z i represents the rate of longitudinal deformation of the i-th box surface that has occurred; e 02 and E 03 represent the yield strength and tensile strength, respectively, of the intelligent batch meter housing material;
S5, setting an inclination angle threshold value of the next use period by using inclination condition information of all the use periods of the intelligent metering box, which are already experienced, of the threshold value adjusting coefficient set; wherein the inclination angle threshold is obtained by the following formula:
Wherein α represents a tilt angle threshold; alpha 0 denotes a preset initial tilt angle threshold; lambda threshold adjustment coefficient; n represents the total number of tilt alarms for all usage cycles that have been experienced; alpha si represents the actual tilt angle of the ith tilt alarm; alpha i represents a tilt angle threshold corresponding to the ith tilt alarm.
The technical scheme has the effects that: according to the technical scheme, the inclination angle of the intelligent metering box is monitored in real time by using the inclination sensor, and the intelligent metering box is transmitted to the MCU controller for processing. The monitoring mode can improve the measurement accuracy of the inclination angle, so that the environment state of the intelligent metering box can be judged better. When the inclination angle obtained by the inclination sensor exceeds a preset inclination angle threshold value, the MCU controller can judge that the current intelligent metering box is in a dangerous environment and send alarm information to the main station. This way of determination may improve the safety and reliability of the device.
The technical scheme of the embodiment utilizes the MCU controller to monitor the use time length of the intelligent metering box in real time, and adjusts the inclination angle threshold value at the end time of the use period. Meanwhile, the threshold adjustment coefficient is set by combining the use time length of the intelligent metering box with the weight information of the current intelligent metering box, and the inclination angle threshold of the next use period is set by utilizing the inclination condition information of all the use periods of the intelligent metering box which are already experienced by the coefficient set. The dynamic adjustment mode can improve the accuracy of threshold setting and better adapt to different environments and application requirements.
Meanwhile, the data and the program of the device are stored and updated through the storage devices such as the memory and the flash module, and the reliability and the flexibility of the device are improved. Meanwhile, remote updating and upgrading of data can be realized, and convenience is brought to a user for maintenance and management. In addition, the above technical scheme of the embodiment integrates various functional modules, including an MCU controller, an inclination sensor, a measurement switch, a Bluetooth intelligent lock, a sensor group and the like, and can realize functions of electric energy metering, monitoring, control, sensing of environmental parameters and the like. Meanwhile, the method can be expanded and customized according to the requirements of users, and the requirements of different application scenes are met.
On the other hand, the inclination threshold value obtained through the formula can be adjusted in real time according to the service life and the loss degree of the intelligent metering box, and the problem that the protection performance is reduced can appear along with the increase of the service life due to the shell metal of the intelligent metering box, so that the accuracy of threshold value setting and the matching performance between the threshold value setting and the actual condition of the intelligent metering box can be further improved by combining the change condition of the shell metal of the intelligent metering box. By setting the threshold adjustment coefficient by combining the use duration and the weight information, the use state and the wear degree of the intelligent metering box can be reflected more accurately.
