The technical problem to be solved in the present invention is to provide a kind of Domestic combustible gas wireless monitoring alarming device, flexible for installation, and fast, networking is convenient, without cabling.
The present invention adopts following technological means to realize goal of the invention:
A kind of Domestic combustible gas wireless monitoring alarming device, comprise substation concentrator, it is characterized in that: described substation concentrator is by wireless network and monitoring, alarming terminal communication, described monitoring, alarming terminal comprises microcontroller, and described microcontroller connects power module, combustable gas concentration monitoring modular, light warning indicating module, audible alarm module, self-inspection key-press module, solenoid valve control module and wireless communication module one respectively.
As the further restriction to the technical program, described substation concentrator comprises controller, and described controller connects power module, wireless communication module two, GPRS communication module respectively, corrects clock module and power supply indicating module.
As the further restriction to the technical program, described wireless communication module one and wireless communication module two adopt 2.4G wireless communication module.
As the further restriction to the technical program, described substation concentrator is by GPRS network and master station communication.
As the further restriction to the technical program, each described substation concentrator and 1023 monitoring, alarming terminal communications.
As the further restriction to the technical program, described controller also connects input keyboard.
As the further restriction to the technical program, described microcontroller adopts STC15W201S single-chip microcomputer.
As the further restriction to the technical program, the pin 1-5 of described microcontroller is connected described wireless communication module one with pin 20, described microcontroller pin 11 connect described self-inspection key-press module, the pin 9 of described microcontroller connects described audible alarm module, the pin 14 of described microcontroller connects described light warning indicating module, described microcontroller pin 18 connect described solenoid valve control module, described microcontroller pin 19 connect described combustable gas concentration monitoring modular.
Compared with prior art, advantage of the present invention and good effect are: the high frequency wireless communication technology adopting 2.4G between substation concentrator of the present invention and monitoring, alarming terminal, it communication distance can reach 150m, make whole building or several building can share a substation concentrator.Substation concentrator transports through GPRS communication mode with the data between main website, and substation concentrator adopts the shell of complete waterproof anti-explosion, meets reliability and real-time simultaneously, and guaranteeing still can reliable communication under severe site environment.Each substation concentrator can connect 1023 monitoring, alarming terminals, substation concentrator and main website can real-time Communication for Power, complete the real-time exchange of data, substation concentrator is provided with input through keyboard interface, and the parameter of substation concentrator can send by main website the parameter set to substation concentrator.Each monitoring, alarming terminal has an address, by the address bit in packet, the identification of substation concentrator is the information which monitoring, alarming terminal sends, main website can arrange the time interval of substation concentrator and monitoring, alarming terminal transmission data, all operations can by host computer by communication setting, and systematic parameter comprises address, baud rate, humiture alarming value, combustable gas concentration limit value etc.Owing to adopting wireless transmission, so without cabling, solving the trouble that cabling brings so at all, by using wireless monitoring terminal, the investment of cabling can be saved.
