Embodiment

Below in conjunction with accompanying drawing, specific embodiment of the invention is described, should be appreciated that exemplifying embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.

As shown in Figure 1, traffic lights remote emergency control device comprises networking interface module, main control module, relay and the power module with wireless communication function, described main control module comprises microprocessor, indicator light circuit and crystal oscillating circuit, and described indicator light circuit and crystal oscillating circuit are electrically connected to respectively on microprocessor; Described relay is electrically connected on microprocessor by some light emitting diodes; Described power module provides working power to Network Interface Module, main control module, relay respectively, the described Network Interface Module with wireless communication function is selected GPRS module or WIFI module, described Network Interface Module carries out communication by RXD and TXD signal wire and main control module, and the data of control module are accessed to INTERNET network connection Master Direction Center server by network interface, realize transmitted in both directions.

Fig. 2 is the specific embodiment of the invention circuit theory diagrams, as shown in Figure 2:

Described main control module is included as the microprocessor of SRC10F08 model, the voltage stabilizer V22 that model is 7805, pilot lamp LED13 and by G1, C1, the crystal oscillating circuit that C2 forms, the input end of V22 is connected after the diode V21 of company with cathode output end of power module, output terminal respectively with capacitor C 13, C15, 38 pin of C19 and microprocessor are connected, the datum line of voltage stabilizer V22 respectively with the public terminal GND of power module, capacitor C 12, C13, C15, 16 pin of the other end of C19 and microprocessor CPU are connected, 8 pin resistance in series R9 of described microprocessor and the rear ground connection of

LED
