Abstract
The invention discloses a poisonous and harmful gas monitoring system, comprising a gas detection unit which uses a gas probe to detect gas. The monitoring system is characterized by further comprising a gas heating unit which heats gas to a temperature at which the gas probe works normally, a central processing unit which analyzes data acquired by the gas probe and a network unit which realizes long-distance transmission of the data, wherein gas in the gas heating unit is pressed into the gas detection unit by using a negative pressure membrane gas pump, and the data acquired by the gas probe in the gas detection unit is transmitted to the central processing unit for analysis. The invention has the following beneficial effects: before detection, the gas is heated by the gas heating unit to ensure normal working of the gas probe in the gas detection unit, thereby guaranteeing accuracy and reliability of detection results; combination of wireless data transmission, wired data transmission and Beidou satellite data transmission is employed, so complementary effects are obtained, and the poisonous and harmful gas monitoring system is applicable in a severe field environment.
Description
Technical field
The present invention relates to a kind of monitoring system, be specifically related to toxic and harmful monitoring system, belong to environmental monitoring field.
Background technology
The sensor that detects toxic and harmful, major part is all by the mode of galvanochemistry and catalytic combustion, gas data to be analyzed.But under high and cold environment, most electrochemical sensor probe all cannot be worked normally, and do not have in the wild in the situation of wireless network covering, be difficult to data to carry out long-distance transmissions, so, general harvester and harmful gas sensor all cannot be in the wild and extremely frigid zones carry out work, therefore a lot of field extremely frigid zones is just very difficult monitors and early warning toxic and harmful.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention 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 present invention adopts following technical scheme:
A 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 gas probe normal operation,
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:
Time timing unit: by the data joining day collecting.
Usefulness of the present invention is: before gas detects, first by gas-heated unit, heated, guaranteed the normal operation 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 invention;
Fig. 2 is the fundamental diagram of gas monitoring system of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
See figures.1.and.2, toxic and harmful monitoring system of the present invention, 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 temperature that gas probe works,
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, utilize the RTOS real-time oss embedded software system of unifying to analyze and control, communicate with extraneous warning device, data center etc., reach the object of Monitoring and forecasting system in real-time.
Adopt RTOS real time operating system, to require the data system of Real-time Collection be very reliable and stable to this, 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 a kind of preferred scheme, 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,
When temperature monitoring probe monitors the temperature that temperature can 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 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 invention also comprises: for data being carried out to the network element of long-distance transmissions.
As a kind of preferred scheme, 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 a kind of preferred scheme, gas monitoring system of the present invention 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, during device looses power, can switch by lithium battery and power, send warning, notify related personnel to check, reach and give warning in advance.
As a kind of preferred scheme, gas monitoring system of the present invention also comprises: time timing unit.Time timing unit Main Function is for by the data joining day collecting, and by built-in RTC, the Time of Day of image data etc. can be reported in detail.
Gas monitoring system of the present invention, because gas is first heated by gas-heated unit before detection, so guaranteed the normal operation 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.
It should be noted that, above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
