Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of monitoring system that is applicable to field extremely frigid zones toxic and harmful monitoring, and this monitoring system can realize real-time monitoring and early warning.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of toxic and harmful monitoring system, comprises detection of gas unit: utilize gas probe to detect gas, it is characterized in that, also comprise:
Gas-heated unit: the temperature by gas-heated to the normal work of gas probe,
CPU (central processing unit): the data analysis that gas probe is collected,
Gas in aforementioned gas-heated unit is pressed in detection of gas unit by negative pressure barrier film gas pump, and the data transmission that the gas probe in detection of gas unit collects to CPU (central processing unit) is analyzed.
Aforesaid toxic and harmful monitoring system, is characterized in that, aforementioned gas-heated unit comprises: temperature monitoring unit and switch control unit.
Aforesaid toxic and harmful monitoring system, is characterized in that, also comprises:
Network element: data are carried out to long-distance transmissions,
Aforementioned network unit comprises: cable network unit, radio network unit and Big Dipper data cell.
Aforesaid toxic and harmful monitoring system, is characterized in that, also comprises:
Power Management Unit: other unit in system provide power supply,
Aforementioned power source administrative unit comprises: lithium battery power supply unit and discharge and recharge control module.
Aforesaid toxic and harmful monitoring system, is characterized in that, also comprises:

Usefulness of the present utility model is: before gas detects, first heated by gas-heated unit, guaranteed the normal work of gas probe in detection of gas unit, thereby guaranteed accuracy and the reliability of testing result; Adopt Wireless Data Transmission, cable data transmission, big-dipper satellite data transmission to combine, reached the effect complementing one another, be applicable to field and dislike slightly environment.
Accompanying drawing explanation
Fig. 1 is the composition schematic diagram of gas monitoring system of the present utility model;
Fig. 2 is the fundamental diagram of gas monitoring system of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
See figures.1.and.2, toxic and harmful monitoring system of the present utility model, comprising:
Detection of gas unit: utilize gas probe that gas is detected, analyzed, then gas is discharged and surveyed cavity, gas probe is arranged on the wall of surveying cavity,
Gas-heated unit: before gas enters detection of gas unit, gas is heated, make the temperature of gas reach the normal temperature of working of gas probe,
CPU (central processing unit): the data analysis that gas probe is collected;
Wherein, gas in gas-heated unit is pressed in detection of gas unit by negative pressure barrier film gas pump, gas probe in detection of gas unit carries out data acquisition, the data transmission collecting to CPU (central processing unit) is analyzed, for example, embedded software system is analyzed and control to utilize RTOS real-time oss to unify, and communicates with extraneous warning device, data center etc., reaches the object of Monitoring and forecasting system in real-time.
Adopt RTOS real time operating system, very reliable and stable to this data system that requires Real-time Collection, ageing height, supporting embedded software system, mainly for parsing, analysis, the data of sensing data report message encapsulation, report the issuing etc. of steering order.
As the preferred scheme of one, gas-heated unit comprises: temperature monitoring unit and switch control unit.
Temperature monitoring unit comprises: temperature monitoring probe,
Switch control unit comprises: control the switch that electric heater unit opens and closes,
In the time that temperature monitoring probe monitors the temperature that temperature can normally work lower than gas probe, notice switch control unit starts electric heater unit automatically, the gas-monitoring of suction is heated to the temperature that can normally work to reach gas probe.
For effective solution does not have, in the situation of wireless network covering, to be difficult to data to carry out the problem of long-distance transmissions in the wild, gas monitoring system of the present utility model also comprises: for data being carried out to the network element of long-distance transmissions.
As the preferred scheme of one, network element comprises: cable network unit, radio network unit and Big Dipper data cell, three has reached the effect complementing one another after integrating, and is particularly useful for field and dislikes slightly environment.
Once due to equipment power down, the external world cannot predict, for fear of the generation of this situation, as the preferred scheme of one, gas monitoring system of the present utility model also comprises: Power Management Unit.This Power Management Unit provides power supply to other unit in system, and it comprises: lithium battery power supply unit and discharge and recharge control module, when device looses power, can switch by lithium battery and power, send warning, notify related personnel to check, reach and give warning in advance.
As the preferred scheme of one, gas monitoring system of the present utility model also comprises: time timing unit.Time timing unit Main Function is by the data joining day collecting, and the Time of Day of image data etc. can be reported in detail by built-in RTC.
Gas monitoring system of the present utility model, because gas is first heated by gas-heated unit before detection, so guaranteed the normal work of gas probe in detection of gas unit, thereby guaranteed accuracy and the reliability of testing result, be particularly useful for field extremely frigid zones and use.
