Description
Technical field
The utility model relates to the monitoring field of the environment of endangering, specifically a kind of danger environment precaution EW system that relates to.
Background technology
Relate to danger environment mainly refer to have an accident possibility large and the uncertain occasion of occurrence time or environment, such as: forest, the dangerous material storage ground, the dangerous material that easily produce dumping place that harmful gas gathers, easily breaking out of fire in transit wait; Carry out long term monitoring to relating to the danger environment; be beneficial to the monitoring personnel and in time find to relate to the abnormal of danger environment; the hidden danger that eliminating may cause accident to occur; even accident occurs; the monitoring personnel are known relating to danger very first time of having an accident of environment; make reasonable arrangement, in time accident is processed, avoid the loss that accident causes further to enlarge.
According to the difference that relates to the danger environment; the monitoring means that adopts is also not identical; forest with easy breaking out of fire; monitor forest fire with weather satellite at present, but when using weather satellite to monitor, the hot spot monitoring error is larger; and easily be subject to blocking of cloud and mist; often can cause and can not locate and monitor accurately, timely the place where the accident occurred, in addition, the fault of satellite itself also can affect location and the monitoring of focus.
Summary of the invention
The utility model is implemented effectively monitoring in order to relate to the danger environment to forest, dumping place etc., and a kind of danger environment precaution EW system that relates to is provided.
The utility model is to adopt following technical scheme to realize: relate to danger environment precaution EW system, comprise middle control unit, information acquisition unit, GSM communication unit, implement the power supply unit of power supply for said units, and the remote terminal that is used for receiving early warning signal; Information acquisition unit, GSM communication unit are connected with middle control unit; Described middle control unit adopts chip microcontroller; Described information acquisition unit comprises for gathering the monitoring means that relates to the danger gas parameter in the monitored area, the positioning unit that is used for determining position, monitored area coordinate, wherein, monitoring means is made of gas sensor and signal processing circuit, the gas sensor output terminal is connected with the single-chip microcomputer of middle control unit through signal processing circuit, positioning unit adopts the GPS receiver to realize, the GPS receiver is connected with the single-chip microcomputer of middle control unit; Described GSM communication unit adopts the gsm module that is equipped with SIM card to realize.
Wherein, relate to easy accidents caused generation in danger gas reference danger environment gas and or accident the gas that produces occurs; Relate to the main reference danger of danger gas parameter gas concentration, under some particular surroundings, also comprise and relate to danger gas type parameter, namely also need detect relating to the danger gas type, the parameters such as described particular surroundings refers in time, temperature, humidity change and cause relating to the more environment of danger gaseous species.
Select the type of gas sensor to be determined by the specific danger gas that relates to that relates to the generation of danger environmental energy in monitoring means; Gas sensor in monitoring means can be the pure gas sensor, can be also the sensor group that the multiple gases sensor consists of.
The course of work of early warning system described in the utility model is as follows: by the parameter state that relates to danger gas in the danger environment that relates to of living in of the gas sensor Real-Time Monitoring in monitoring means, after the signal processing circuit front-end processing, sign there is the electric signal transmission that relates to danger gas parameter information to the single-chip microcomputer of middle control unit, completes the monitoring to the monitored area; By the GPS receiver in positioning unit, the coordinate signal of corresponding monitoring means position is transferred to the single-chip microcomputer of middle control unit, completes the location to the position, monitored area; Judge by single-chip microcomputer whether relate to the concentration that relates to danger gas in the danger environment approaches the warning value of setting; in case approach; single-chip microcomputer will relate to danger gaseous species, concentration and correspondence position coordinate and be sent to remote terminal via the GSM communication unit with short message way; complete early warning; the monitoring personnel are in time known relate to the position coordinates in the abnormal and abnormal place of danger environment, so that it makes reasonable arrangement, the hidden danger that eliminating may cause accident to occur; perhaps in time accident is processed, implemented rescue.
Compared with prior art, the multiple technologies such as the utility model application sensors Signal Collection Technology, single-chip microcomputer signal processing technology, GPS location technology, GSM mechanics of communication are with information acquisition, processing and together with transmission is incorporated into; Obtain the information signal that relates to danger gas by gas sensor, send single-chip microcomputer to after the amplification processing of process front end and A/D conversion, the position signalling that while GPS receiver will relate to danger gas is delivered to single-chip microcomputer, after being processed by single-chip microcomputer, relate to danger gaseous species, concentration and correspondence position coordinates transmission to remote terminal by what the GSM communication module will collect, make the monitoring personnel can in time find to relate to the relevant information of danger gas, in time make Corresponding Countermeasures; And the GPS receiver in the utility model can accurately and timely be located the place where the accident occurred point; make the utility model can effectively solve the problem that existing monitoring means is difficult to accurately, efficiently locate place where the accident occurred point, the utility model can relate to the danger environment to forest, dumping place etc. and implement effectively to monitor.
The utility model is rational in infrastructure, simple, and result of use is good, can play important effect to taking precautions against the related works such as forest fire, enforcement soot monitoring harmful gases and location.
