The effect of this circuit mainly is that the action count signal of importing the lightning arrester that comes is carried out conversion, adapting to the interface level of single-chip microcomputer, thereby better the count signal of lightning arrester discerned,
Single chip circuit is made up of the circuit such as PIC16F628A single-chip microcomputer of Microchip company as shown in Figure 4.Single-chip microcomputer adopts the twin crystal design of shaking, and is worked by low-frequency Y202 crystal oscillator generally speaking, is operated under the sleep state of low-power consumption to guarantee single-chip microcomputer.Three pulse input pin 6,10,11 pin are in the monitoring waiting status all the time, in case voltage pulse signal when input arranged, then 6 of single-chip microcomputer, 10,11 pin will correspondingly be experienced the low level pulse signal.Single-chip microcomputer relies on built-in software that the amplitude of input signal, pulsewidth etc. are discerned processing, after the undesired signal that really admits a fault, wake single-chip microcomputer immediately up, the oikocryst Y2001 that shakes enters duty, the 18 pin output start-up control signal IGT of single-chip microcomputer is to gsm module, start gsm module, enter the information arm-to-arm.Single-chip microcomputer carries out the mode that RS232 communicates by letter by between 7,8 pin and the gsm module, with the AT instruction to the start-up course of gsm module, go into information such as net state and inquire about and detect, start until gsm module and finish.With the action frequency of the lightning arrester after the accumulation process, data such as separate, use way of short messages then, send by gsm module.After information sent successfully, 1 pin of single-chip microcomputer output closing control signal GPD was to gsm module, and gsm module enters off-mode immediately, and single-chip microcomputer also reenters the sleep state of low-power consumption, waits for the arrival of the actuating signal of lightning arrester next time.
Here the single-chip microcomputer of Cai Yonging belongs to universal serial, thereby this circuit also can be realized identical functions by the single-chip microcomputer of other similar brands and model.Among Fig. 3, J201 is the online programming interface, and J202 is the signal gang socket of single-chip microcomputer and gsm module, and J203 is external RS232 interface, is convenient to actual production of the present utility model and debugging etc.
As shown in Figure 1, gsm module is semi-manufacture, and the utility model adopts the TC35I of German SIEMENS (Siemens) company, and TC35I is the highly integrated gsm module of a double frequency 900/1800MHZ, it is easy to integrated, the suitable especially fields such as remote monitoring that are applied in similar native system.TC35I is connected with outside manufacture by the socket of one 40 pin, and function is more, only discusses the implication of the pin relevant with the utility model here.Wherein, 15 pin meet start-up control signal IGT, and 31 pin connect and close machine control signal GPD, and 18,19 pin are RS232 order wires.Gsm module also needs external emitting antenna, and related data is sent out by transmitting.
Gsm module connects the SIM card of the validated user of China Mobile, receive the start-up control signal of single-chip microcomputer, and after finishing normal startup, passing through serial communication mode, be subjected to the AT instruction control of single-chip microcomputer, the data such as action frequency of the lightning arrester mode with SMS is sent.
The utility model also can adopt the gsm module with SMS of other brands and model, just at different modules, should consider conditions such as its operating voltage, electric current, interface pin, and in the use of single-chip microcomputer to the AT instruction of module, be general basically.
Power supply as shown in Figure 5, the utility model adopts the lithium ion battery power supply, the design effort life-span is 3～5 years.Therefore, can work stably in a long term, also be aided with external power supply and replenish for assurance equipment.External power supply of the present utility model has adopted solar cell, the external power source input signal V that solar cell produces
INEnter charging control circuit, form simple and reliable constant-voltage charge control circuit 41, voltage is accurately controlled 4.5V by U801 etc.; This voltage passes through reverse isolation circuit 42 then, thereby avoids the reverse battery electric leakage; Enter battery 43 again, battery is charged; At last, the voltage that comes out from battery enters mu balanced circuit 44, after voltage stabilizings such as Q802, U802, obtains stabilized voltage supply output signal V1 and is supplied in each circuit of the utility model.Owing to adopted the devices such as HT7344 of low-power consumption, so the quiescent current of integrated circuit is controlled in the 60uA.
Another kind of scheme, external power supply also can use miniature aerogenerator, and it is motionless that other circuit parts can keep substantially.If the electric current of the micro wind turbine generator of actual apolegamy is bigger, then U801 can add expansion stream triode, to guarantee that battery overcharge conditions can not occur.
