In order to achieve the above object, the present invention includes emergent stop signal and trigger amplifying circuit, the microprocessor control circuit, the GBT modular circuit that is connected with microprocessor control circuit that are connected with emergent stop signal triggering amplifying circuit and the motor that is connected control with the GBT modular circuit.The optocoupler that emergent stop signal triggers that amplifying circuit comprises scram button, the rc filter circuit that is connected with the triggering signal of scram button, the coupling resistance that is connected with rc filter circuit, the triode that is connected with the output of coupling resistance with base stage and input are connected with the colelctor electrode of triode.The output of optocoupler is connected with the reset terminal of microprocessor.
The model of microprocessor is TMS320LF2401A.6 outputs of microprocessor TMS320LF2401A are connected with 6 inputs of GBT module respectively.
TMS320LF2401A is based on the digital signal controller of microprocessor and 16 40MIPS fixed DSPs, and TIX produces.8K 16 bit flash memory E are arranged in the chip
2PROM, 8K16 position ROM, 1K 16 bit data/program RAM, the RAM of the two accesses of 544 words and reach single access RAM and the guiding ROM of 512 words.Also have in addition 2 16 General timers, 7 16 PWM passages, can and analog/digital conversion synchronously and 10 ADC that 5 multiple connection input channels are arranged, adopt 32 pin VF-LQFP to encapsulate 40 ℃ to 85 ℃ of operating temperatures.It is powerful, and cost is low, serial communication, and controllable motor reduces noise, raises the efficiency.It is respond well to be used for the present invention.
Task of the present invention is exactly to finish like this.
The present invention has abandoned the mechanical button that falls behind and has directly controlled forceful electric power mode and machinery-electrical equipment relay, has adopted the micro-processor interface circuit mode.This circuit is directly controlled by microprocessor, has avoided shock hazard, has improved service life and reliability, has reduced production cost.Can guarantee in emergency circumstances personal safety, minimizing mechanical disorder, meet the CE requirement fully.Can be widely used in the various treadmills.
