The monitoring center comprises a flat computer, a zigbee coordinator and an RFID card reader. After being connected with the zigbee terminals through wires, the chlorine detecting sensor is further wirelessly connected and networked with the zigbee routers and the zigbee coordinator through the zigbee wireless communication technology. The zigbee routers, the zigbee coordinator and the zigbee terminals which all adopt a cc2530 wireless one-chip microcomputer as the core have a 2.4 Ghz working frequency. The flat computer is connected with an acousto-optic linkage alarm device through a wire. The system which has the characteristics of safety, reliability, easy realization and convenient maintenance can effectively prevent false alarms and alarm failures due to the failure of the detecting sensor.
Description
Technical field
The utility model relates to a kind of toxic gas detection alarm system, has been specifically related to a kind of chlorine leakage detection alarm system based on Zigbee-technology.
Background technology
The detection of industrial gasses has very important meaning to industrial safety.The function of industrial gasses detecting instrument is to detect in real time the concentration of gas, the rear warning of transfiniting, the potential safety hazards such as poisoning, fire even blast that caused by inflammable, explosive, toxic and harmful etc. in elimination or the minimizing commercial production minimize property and personal casualty loss.Divide according to the function that realizes, the industrial gasses detecting instrument mainly contains at present: portable or stationary gas detector, gas detection transducer, bus-type gas detection alarm system and wireless gas detection alarm system.
Portable or stationary gas detector generally only has the function of gas concentration detection, onsite alarming, and cost is low, technique is simple, but can not real-time transmission data and remote alarms.Gas detection transducer need to be applicable to the fewer situation of probe node, one tunnel system only monitors a node situation, adopt transmitter output 4-20mA current signal that the multichannel detector is transferred in the control box, reliability is very high, domestic and international application is more extensive at present, but when the node that needs to survey is many, use this line-disparting type alarm to implement very trouble, and expensive.
Along with the development of detection means and the raising of testing requirement, integrated system equipment has become main R﹠D direction.The gordian technique that is designed to cover system equipment is the structure of industrial on-site network.The bus-type gas detection alarm system not only has the function of gas concentration detection, onsite alarming, and has the functions such as remote alarms, data processing.Gas detector adopts the communication port of RS485 mode more at present, therefore alarm controller also adopts the communication modes of RS485 more, the alarm controller of this bus type can be realized the Centralized Monitoring than multinode, but system stability just is difficult to guarantee, when a node breaks down, whole system will be paralysed, and the work that RS485 bus system generally could be reliable when no more than 32 of the nodes that connects; In addition, the installation and maintenance of bus-type gas detection alarm system is complicated, cost is high, flexibility ratio is low, is unsuitable for being difficult to connect up and dangerous place.
Use the wireless gas detection alarm system of GPRS, CDMA technology exploitation, rely on stable, reliable China Mobile GPRS network, adopting advanced and mature GPRS wireless data terminal is remote transmission device, measured TCP/UDP agreement, realize monitoring system data acquisition function, finished industry spot gas detection alarm task.System ovelay range is large, is not subjected to regional limits, but needs special Virtual network operator to come maintaining network, and operation cost is higher, and unfavorable timely discovery field condition the time-delay situation appears, in the data transmission of the GPRS service that China Mobile provides sometimes.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of safe and reliable, be easy to realize, the chlorine leakage detection alarm system based on Zigbee-technology easy to maintenance.
To achieve these goals, the utility model is achieved in that a kind of chlorine leakage detection alarm system based on Zigbee-technology, comprises Surveillance center, zigbee router, zigbee terminal and chlorine detecting sensor; It is characterized in that: described Surveillance center comprises panel computer and zigbee telegon; After being connected with the zigbee tag wire, described chlorine detecting sensor carries out the wireless connections networking by zigbee wireless communication technology and zigbee router, zigbee telegon, described zigbee router, zigbee telegon and zigbee terminal are all take the cc2530 wireless singlechip as core, point-to-point transmission Ju Li＞=20 meter each other, relay Chuan fails Ju Li＞=120 meters.Adopt cc2591+cc2530 zigbee module transmission range can reach 300～500 meters.
The frequency of operation of described zigbee router, zigbee telegon and zigbee terminal is 2.4Ghz.
Described panel computer line is connected with an acousto-optic linkage alarm device.
Described Surveillance center also is provided with a RFID card reader, and carries out wireless connections with the zigbee telegon by the zigbee wireless communication technology.The Card Reader data of RFID card reader are as supervisory system operator on duty attendance record.Panel computer will receive the brushing card data that sends the RFID card reader of returning via zigbee router, Zigbee network coordinator and record; As supervisory system operator on duty attendance record, can be for inquiry, printing.
Described Surveillance center is the monitor supervision platform based on panel computer, can export electronics electrograph and numeral receiving the chlorine gas concentration information rear plate computer that sends each monitoring point of returning via zigbee router, zigbee telegon; When numeral exceeded setting value, corresponding icon reddened and glimmers the light that the acousto-optic linkage alarm device sounds the alarm and glimmers.
The workflow of warning system of the present utility model: swipe the card when the operator on duty goes to work, the information such as operator on duty's identity code, charge time are recorded in the database of panel computer.Sensor passes through the zigbee wireless network with the chlorine gas leakage concentration data that Site Detection arrives, send it back Surveillance center, panel computer in Surveillance center cooperates electronic chart to show gas concentration value, when chlorine gas leakage occurs when, show red alarm icon (record time of fire alarming) on the display screen of the panel computer of Surveillance center on the electronic map location of correspondence, inform the operator on duty, export simultaneously two path control signal, wherein one road signal sends chimes of doom for driving warning circuit, another road signal is used for driving on-the-spot blower fan exhausting, guarantees peripheral personal safety.
The beneficial effects of the utility model:
The multipotency in existing system collection point is realized 30 collection points, and the utility model can be realized 200 more than the collection point; Ad hoc network is adopted in the data wireless transmission, and the energising of zigbee terminal module can oneself network, and layouts flexibly, and it is extremely convenient to install, and the quantity of monitoring point and monitoring is determined by user oneself; Zigbee router, zigbee terminal module belong to low-power consumption, but civil power work, also can be battery operated, use No. 5 battery-powered operation of three joints for up to six months; System carries measuring ability, can prevent the detecting sensor inefficacy and wrong report occur, fails to report.The software interface mapable shows, can judge fast alert locations, and have the function of automatic startup blower fan air draft.Have the RFID card reader, as supervisory system operator on duty attendance record, can and print for inquiry.Native system is widely used in the fields such as metallurgy, oil, chemical industry, water factory, papermaking, gas station, will greatly improve the level of monitoring management.
