See B area part circuit among Figure 10, the port 3 of microprocessor is used to control the driving of light emitting diode matrix, when port 3 is high level, amplifies through triode, lights light emitting diode matrix, and when port 3 was low level, light emitting diode matrix extinguished.
See C area part circuit among Figure 10, the current signal processing unit through jig structure and coil from power circuit mutual inductance to current changing signal, frequency signal and the harmonic wave composition of certain ratio.Through rectification capacitance-resistance circuit, convert voltage signal into, through resistance and catching diode dividing potential drop, be input to the analog to digital conversion input port 6 of microprocessor, as the judgment basis whether load current is arranged in the detection line.
See D area part circuit among Figure 10, the voltage signal of rectification is input to the port 7 of microprocessor after capacitive coupling, triode amplify, as the basis for estimation of judging current break.
The magnetic switch circuit is seen E area part circuit among Figure 10, and when magnetic switch was closed, this state variation was input to the port 4 of microprocessor, and microprocessor gets into the reset test process, gets into operate as normal dress attitude after accomplishing this process.
The under-voltage measuring ability of battery is all realized by the microprocessor internal resource.The microprocessor model of selecting for use is 16F1822, the integrated 2.048V fixed voltage reference module of this chip internal, and one can external reference power source (cell voltage) resistance pressure-dividing network.The analog to digital converter (AD) that this chip is also integrated 10, can select the 2.048V fixed voltage reference is the conversion reference voltage of AD, cell voltage converts digital quantity by AD through the resistance pressure-dividing network of inside after the dividing potential drop.Microprocessor periodic measurement cell voltage converts digital quantity Nx into, if the threshold value Ny of this measured value during less than the cell voltage lower range, then this battery of decidable is under-voltage.
The MCU microprocessor is as core calculations and control module, accomplishes the response of the seizure, the conversion of line current of ground voltage, detection that battery is under-voltage, test reset, the function of driving that color break-up shows.The voltage of microprocessor monitors power circuit powers on when detecting power circuit, surpasses after the delay time of adjusting, and just opens circuit fault judgement monitoring function; When detecting the power circuit power down, shut-down circuit fault judgement monitoring function powers on up to detecting power circuit immediately, opens circuit fault judgement monitoring function once more.The misoperation that reclosing caused when this method can effectively be avoided fault.
This microprocessor can also extend out communication and the parameter tuning that wireless radio frequency modules is accomplished failure message.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection domain that also should be regarded as the utility model.
