Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.
A kind of Coal Mine Safety Monitoring System based on ZigBee wireless network, its structure is as it is shown in figure 1, include supervisory controller, embedded gateway controller, ZigBee coordinator, terminal node, mining gas sensor；Terminal node, mining gas sensor are arranged on underground coal mine needs the regional of monitoring, the outfan of mining gas sensor connects the input of terminal node, terminal node interconnects with ZigBee coordinator, and embedded gateway controller interconnects with ZigBee coordinator and supervisory controller respectively.
Mining gas sensor is for the concentration value of collection of coal mine down-hole each point gas, and passes to terminal node in real time.In the present embodiment, mining gas sensor uses MC114, its fast response time, has good repeatability and selectivity, bridge output voltage linearly, stable, reliable.
Terminal node has ZigBee module, is used for controlling mining gas sensor and gathers data and collect the data gathered, and is communicated with ZigBee coordinator by ZigBee-network.Terminal node has the low-power consumption feature of asynchronous sleep, and all terminal nodes can enter resting state during not gathering data, to realize low-power consumption, is in the terminal node of resting state, wakes up at regular intervals once, and that monitors coordinator wakes up instruction up.Receiving after coordinator wakes up instruction up, i.e. start mining gas sensor and gather data, data to be collected complete, and send data to coordinator by RF communication.Terminal node uses battery to power, and saves the loaded down with trivial details technique of Kuang Xia placement-and-routing, and terminal node is bound with ZigBee coordinator after powering on automatically, completes Tong Bu with other terminal node in ZigBee wireless network under the dormancy of ZigBee coordinator instructs.
ZigBee coordinator, for communicating with embedded gateway controller and all terminal nodes, coordinator management great amount of terminals node, information interaction amount is big, does not enter low-power consumption mode, uses 5V DC source to power.The structure of ZigBee coordinator is as shown in Figure 2, antenna, reset circuit, crystal oscillating circuit, peripheral circuit, power management module, serial port module, information interactive module and the alarm module including microprocessor and being connected with microprocessor respectively, serial port module preferred RS232 serial port module.
ZigBee coordinator has the function controlling all terminal simultaneously operatings, wakes up all dormancy terminal nodes up simultaneously, makes all terminal nodes gather Data Concurrent at synchronization and delivers to coordinator, in order to the analysis of overall data and process.Having two kinds of control models, one is automatic mode, periodically sends to wake up up to instruct and arrives terminal node, and order terminal node gathers data, then uploads to embedded gateway controller；Another kind is manual mode, when monitoring personnel think to check at once methane gas concentration levels under current ore deposit, can wake up all terminal nodes immediately up by commands coordinate device, carry out data acquisition.
Microprocessor uses the CC2530 chip of TI company, this integrated chip high-performance and 8051 microcontroller cores of low-power consumption, has high receiving sensitivity and interference free performance.
