Embodiment
Referring to Fig. 1, setting is the data processing of core and the control center of display driver with Chip Microcomputer A tmega8, when detect detect button and press after, carry out start-up operation, the DC component that blower fan generating is obtained behind AC-DC and current rectifying and wave filtering circuit is sent to single-chip microcomputer with the DC component of solar electrical energy generation through the electric current and voltage Acquisition Circuit, is used to gather blower fan and the solar panels duty of generating electricity.And come judgment task whether unusual with this, if unusual, then by warning circuit, output alarm, prompting and display abnormality parts.If it is normal then show the electric current and voltage information of operate as normal.Battery condition is monitored, shown its voltage and battery charging state, the display system operating ambient temperature.
Figure 2 shows that the battery tension Acquisition Circuit, for battery tension U1, the bleeder circuit that utilizes resistance R 1 and R2 to form is got the voltage on the R2, and itself and VCC are compared.When being higher than supply voltage VCC, diode D1 is with conducting, and at this moment, Chip Microcomputer A C pin is pulled to high level; When being lower than benchmark ground GND voltage, diode D2 conducting, Chip Microcomputer A C pin is pulled down to low level; When input voltage was between earth potential and VCC, Chip Microcomputer A C pin detected the terminal voltage on the divider resistance R2.
Shown in Figure 3 is to indicate with LED lamp D5 whether 2 inputs of photovoltaic voltage U serve as normal, and when sun power was normally imported, LED lamp D5 lighted.Form bleeder circuit by resistance R 3 and R4, Chip Microcomputer A C2 pin detects the dividing potential drop on the resistance R 4; Capacitor C 4 is used to guarantee that the detection input of this pin can not suddenly change, and stabilivolt D4 is used to protect the voltage on the Chip Microcomputer A C2 pin to be unlikely to too high.
Shown in Figure 4,12864 type LCD Liquid Crystal Modules drive the control signal that three pins need be arranged, choose display screen by the CS chip selection signal respectively, under SCLK clock signal condition, the data or the operational order of a byte of transmission in per three the byte pulse signals of SID pin, thereby show detected voltage data and environmental data, this operation is finished by the single-chip processor i/o pin.
Shown in Figure 5, keyboard scanning circuit, often drive button by pull-up resistor R1 and R2 series connection, form the keyboard scan hardware circuit, be connected with 4 I/O mouths of single-chip microcomputer,, detect PD3 by to PD1 and PD2 difference input low level, PD4 mouth level changes judges which key is pressed, and determines whether to carry out respective operations.
Referring to Fig. 6, system of the present invention working procedure is as follows:
After the single-chip microcomputer energising, move initialize routine automatically, peripheral button is carried out keyboard scan press to have determined whether button, press as button, then executive routine signal that the electric current and voltage Acquisition Circuit is sent here carries out the AD conversion, and simulating signal is converted into digital signal, has judged whether fault.If fault is arranged then the output alarm control signal, and carry out the LCD transmitting control commands and carry out display operation, fault type is sent to display screen with data layout.If there is not fault, then carry out the program that shows current voltage, equipment work temperature.
