Embodiment Construction

[0015] see figure 1 and figure 2 , including a single-chip microcomputer, the single-chip microcomputer is respectively connected with the external current sensor and the whole group of voltage sensors through the ADC circuit, and the single-chip microcomputer is also connected with a temperature and humidity measurement module, a communication module, a display module, a storage module and a watchdog circuit. The single-chip microcomputer is W77E516B- DIP40 type microcontroller. The ADC circuit uses a serial TCL2543 circuit, the reference uses REF198 (4.096V), channel 0 online monitors the charging current, channel 1 online monitors the discharge current, and channel 5 sets the voltage. The voltage signal output by the sensor is followed by the 324 op amp and input to the ADC. The RS485 bus is used to communicate with the collector, UART0 of the CPU is used, and the baud rate = 19200 is realized through MAX485, which is generated by the T1 timer. Communication with PC uses...
