The utility model content
The purpose of the utility model is in order to overcome the weak point of prior art; The gas concentration remote detection device that can adapt to field extreme environment that provides a kind of sensor probe to separate with operating terminal; The position of detection probe can be deployed in the place that any GPRS network covers as required; Operating personnel can or carry out long term monitoring to the strange land field environment away from check point, avoid the interference to environmental parameter, avoid the harmful effect of hostile environment to operator ' s health simultaneously.
The utility model is realized through following technical scheme:
Said field environment gas concentration remote detection device comprises wireless gas concentration detection probe and the host computer operating terminal that links to each other through the GPRS wireless network.
Said wireless gas concentration detection probe comprises Single-chip Controlling processing module and the gas concentration detection module, state indicating module, power module and the GPRS wireless communication module that link to each other with said Single-chip Controlling processing module respectively, and said gas concentration detection module, GPRS wireless communication module also link to each other with said power module.
Said host computer operating terminal is any computer equipment with program run function, data processing function and Internet connection function, like server, workstation, PC or notebook.
Said GPRS wireless communication module is connected with the Single-chip Controlling processing module through serial ports.
Said GPRS wireless communication module inserts Internet through GPRS network and communicates by letter with said host computer operating terminal.
The number of said wireless gas concentration detection probe is more than or equal to 1.The user can adopt a host computer operating terminal to connect many wireless gas concentration detection probe simultaneously as required, realizes that multiple spot detects simultaneously.
The beneficial effect of the utility model is following:
(1) realized that the control of data manipulation and parameter separates with sensor is popped one's head in, avoided operating personnel the injury of the interference of testing result and hostile environment to operating personnel;
(2) because the GPRS radio communication is not limited by length of cable; Fixing host computer operating terminal and the wireless gas concentration detection probe is deployed in the place that any GPRS network covers; The wireless gas concentration detection probe can also receive the remote control signal of host computer operating terminal; Revise the parameter of detection probe, satisfy the detection demand more neatly;
(3) each module of this device has been carried out Anti-interference Design, can adapt to open-air abominable working environment fully.
