Embodiment
Referring to Fig. 1, system is made up of with the monitoring PC the ZigBee network that each node is formed jointly, and the data that are placed in each terminal node collection of students' dormitory are converged by coordinator node and are transferred to PC and then supply the operator on duty to keep watch on through its serial ports.
Each node circuit realizes that block diagram is as shown in Figure 2, and all adopting wireless built microprocessor TICC2430 is that core designs, and it has the distinguishing feature of low-power consumption.Router node adopts lithium battery power supply to be convenient to be placed in flexibly on the wall or ceiling in corridor; Terminal node is placed on the ceiling in the middle of the dormitory (helping inconvenient artificial destruction) usually; Coordinator node is placed in the duty room; Consider the power consumption of sensor detection circuit, circuit for alarming and the convenience that power supply obtains; They adopt power supply adaptor power supply (do not receive regularly signal of communication if the people, keeps watch on PC for pulling out power supply, will on PC, show alarm).
Sound intensity intensity detection is considered the reliability and the low cost property that this testing circuit has of detection referring to Fig. 3, realizes that by the circuit of two one spline structures Fig. 3 only provides a figure, and another graph structure is just the same, and just the P1.1 mouth of CC2430 is delivered in output.Adopt post pole body microphone as surveying sonic transducer; Its resistance value changes with sound intensity intensity; Realize the differentiation of sound intensity intensity by the LM393H comparer; Its in-phase input end rheostat is used to set sound intensity intensity discre value, and result relatively send the P1.0 mouth of CC2430, and the CC2430 software program is designed to the external interrupt input port with P1.0, P1.1 mouth.If detect signal, regularly 5 minutes, per minute detected 2 times, if repeated detection arrives, explanation is a voice but not other of short duration back drop sends caution signal to telegon in such cases.Timing obtains the chip like DS1302 from real time clock circuit.The time that sound intensity intensity begins to detect is set by the monitoring PC, and is definite according to school's daily schedule.
The light intensity intensity detection is considered the reliability and the low cost property that this testing circuit has of detection referring to Fig. 4, realizes that by the circuit of two one spline structures Fig. 4 only provides a figure, and another graph structure is just the same, and just the P1.3 mouth of CC2430 is delivered in output.The light intensity Strength Changes is through photoresistance R1 perception; Reduce along with light intensity intensity increases its light resistance value, R1 can be Q1 enough bias currents is provided, and standardsizing rheostat is set light intensity intensity discre value makes Q1 be in state of saturation; The P1.2 mouth that CC2430 is delivered in the pulse of output negative edge triggers break detection; If detect signal, be difference undesired signal timing 5 minutes, disposal route is the same with sound intensity intensity.
Smoke Detection adopts MQ2 as smoke transducer referring to Fig. 5, considers the reliability of detection and the low cost property that this testing circuit has; Circuit by 3 one spline structures is realized; Fig. 5 only provides a figure, and two graph structures are just the same in addition, and just P1.5, the P1.6 mouth of CC2430 delivered in output.Increase along with smokescope; The increase of MQ2 resistance makes Q1 be in state of saturation; The P1.4 mouth that CC2430 is delivered in the pulse of output negative edge triggers break detection, sends data to the telegon warning as two above sensor immediately to smog and also reports to the police through circuit for alarming at the scene.
Each node of native system all uses the ZigBee wireless communication protocol stack, and wherein the terminal node operation is the RFD code; What routing node and coordinator node were moved is the FFD code.The ZigBee telegon is responsible for initiating, setting up the ZigBee cordless communication network of native system; Terminal node is write out Interrupt Process function, real-time clock read in the application layer of protocol stack, realizes obtaining of each sensor and clock data, and invocation protocol stack data are sent overall situation function then, realizes the wireless transmission of sensing data.The data that each terminal node transmits are finally converged by telegon and are transferred to the monitoring PC through serial ports, and data encoding format comprises dormitory number, caution type, and wherein sound intensity intensity coding is caution type 2 for caution Class1, light intensity intensity coding; Smog is encoded to caution type 3.On PC, write Delphi, SQL database application program, finally through PC storage with provide and be shown to the operator on duty.
