Embodiment
Below in conjunction with accompanying drawing and embodiment the present technique scheme is described.
Fig. 1 is the overall system design block diagram of this device, comprises MCU master controller, inflammable gas sensor assembly, power-supplying circuit, LCD display module, alarm module, power failure protection module, Power Line Carrier Communication Module, receiving terminal; Inflammable gas sensor assembly, power-supplying circuit, LCD display module, alarm module, power failure protection module, Power Line Carrier Communication Module all are electrically connected in the MCU master controller.Data after Power Line Carrier Communication Module will be handled are coupled to line of electric force, and the receiving end Power Line Carrier Communication Module receives and demodulates data message from line of electric force and sends to receiving terminal.
Fig. 2 is the power line carrier module frame chart of this device, and Power Line Carrier Communication Module comprises communication interface modules, microcontroller, modulation module, power line interface.Through communication interface modules data message is sent to Power Line Carrier Communication Module, is coupled to line of electric force after the processing, give receiving terminal with information through the receiving end Power Line Carrier Communication Module through the modulation module.
Fig. 3 is the software program flow chart of this device.System is initializing circuit at first, detects inflammable gas concentration and concentration value is presented on the LCD display module in real time, judges that whether inflammable gas concentration is greater than the preset concentration value; If not; Then continue detectable concentration, if concentration greater than the preset concentration value, is then opened hummer; Send warning message to receiving terminal through Power Line Carrier Communication Module, thereby and break off general supply in the solid-state relay disconnection chamber.
Principle of work: the MCU master controller is the core of this device, and the inflammable gas sensor assembly arrives the MCU master controller with real-time detected data delivery, so that analyze and operate.Power supply module is that whole device provides+power supply of 5V; The LCD display module is used to show real-time detected data message and preset inflammable gas concentration threshold; When real-time concentration has reached preset inflammable gas concentration threshold, promptly start warning device and power failure protection module, and warning message is sent to receiving terminal immediately through power line carrier communication; So that in time adopt remedial measures, avoid occurring major casualties and property loss.Power line carrier communication is to utilize the existing power spider lines to carry out a kind of communication mode of information transmission.
