16 bit timing devices, WatchDog Timer, and 16 I/O pin embedded UART, SPI, IIC able to programme
Interface, temperature sensor 13 uses the DS18B20 type temperature sensor of DALLAS company of the U.S., merchandiser sheet
Machine 11 have only to I/O connect just can both-way communication, support the measurement scope of-55～125 DEG C, there is body
Long-pending little, hardware spending is low, and capacity of resisting disturbance is strong, precision advantages of higher.First wireless transport module 12 and
Two wireless transport modules 21 use cheap n R F24L01 type radio transmitting and receiving chip, with single-chip microcomputer 11 passes through
SPI interface carries out communication, and programming is simple, easy to use.
Power supply unit 14 is powered for temperature sensor the 13, first wireless module 12 and single-chip microcomputer 11, described temperature
The disconnecting switch edge of a knife that degree sensor 13 is arranged in switch cubicle, contact, at busbar shiplap joint, cable connector etc.
Needing carry out temperature detection at thermometric and transducing signal is transferred to single-chip microcomputer 11, described single-chip microcomputer 11 is by first
Wireless module 12 and the second wireless module 21 carry out radio communication, are transferred to the transducing signal received survey
Temperature main frame 2, thermometric main frame 2 carries out process to transducing signal and is converted into temperature value, and compares with preset value,
When temperature anomaly occurs, such as: contact temperature exceedes certain environment temperature or contact temperature rise within a certain period of time
Exceed uniform temperature, then output alarm signal is reported to the police to alarm module 3, and alarm module 3 includes including honeybee
Ring device and LED, when receiving alarm signal, buzzer buzzing, LED flashes to remind patrol officer
Switch cabinet temperature occurs abnormal, need to process in time, meanwhile, and will by wire communication such as RS485 bus
Temperature value and transmitting fault information show to long-range monitoring client 5 (such as PC or PLC), in order to patrol and examine
Personnel check, patrol officer can also revise setting value by long-range monitoring client 5 and remotely control,
Thermometric main frame 2 is also associated with display module 4, and in the present embodiment, display module 4 is touch screen, patrol officer
Touch screen query temperature value and warning message can be passed through.
Sensor node uses 3.3V to power, and duty has 2, state 1: only single-chip microcomputer 11 is in work
Make,；State 2: temperature sensor 13 receives the order of thermometric main frame 2 and is acquired temperature, temperature passes
Sensor 13 and the first wireless module 12 are all in work.Respectively to the merit under 2 states of 6 sensor nodes
Consumption takes multiple measurements, and the average power consumption recorded is shown in Table 1.
Table 1 sensor node measurement of power loss result
Finding out as known from Table 1, the power consumption of sensor node is the lowest.
This utility model uses cheap n R F24L01 wireless module composition wireless sensor network, n R
F24L01 radio transmitting and receiving chip uses one-to-many pattern, has 6 from machine (the first wireless module) and 1 master
Machine (the second wireless module), from machine and with main frame between can both-way communication, and can automatic-answering back device, n
The power consumption of R F24L01 radio transmitting and receiving chip is the most at a fairly low, and when working in the transmission mode, current drain is
11.3mA, is that under 12.3mA, power-down mode and standby mode, current drain is lower during reception pattern, packet
Can transmit the data of 1～32Byte, communication speed reaches as high as 8Mbit/s every time, is suitable for various monolithic
Machine connects, and is suitable for this utility model.
N R F24L01 radio transmitting and receiving chip only have the identical passage in address just can mutually communication, but all n R
The passage 1～5 of F24L01 radio transmitting and receiving chip can only receive data and can not send data, only passage 0
Can be with bi-directionally sent data, this is also that the address of why passage 0 is 40 and can arbitrarily rewrite, and other lead to
Relatively-stationary reason is wanted in first 32 of road.It is passage 0 ground with sender by the reception channel address of recipient
As location is set as, after reception channel reception to one's own data, will be using the address of oneself as response
The reception address of signal, sends response signal automatically to the passage 0 of the other side.In this utility model, work as main frame
When Xiang Congji sends data, make passage 0 location from machine of itself and data to be received by rewriting the address of passage 0
Identical, just can be successfully transmitted data and accept response signal；When main frame is in time receiving data from machine, and main frame leads to
The address in road 0～5 corresponds respectively to passage 0 address from machine 1～6, and ability successful data reception also sends
Response signal.Main frame with from machine communication schematic diagram as shown in Figure 2.
Sensor node can receive, every 1h, the order that thermometric main frame 2 is sent, and is acquired temperature and leads to
Cross the first wireless module 12 and be sent to thermometric main frame 2.The power consumption of sensor node is mainly the first wireless module
12, and all in standby mode when the first wireless module 12 is flat, power consumption is extremely low, this ensures that theres sensor
Node uses battery to power and also can work long hours.It addition, the A/D module of single-chip microcomputer 11 can also be single to power supply
The voltage of unit 14 is monitored, and when brownout, sensor node will send alarm signal to thermometric main frame 2
Cease and quit work.The workflow diagram of sensor node is as shown in Figure 3.
In the present embodiment, data collecting system and data monitoring management system are except communication object and data process side
Beyond formula difference, other functions are essentially identical.Mastery routine circulation primary per second, the temperature sensor 13 that will receive
Transducing signal be acted upon, as temperature the most then continues cycling through, the most then eject alarm screen if any abnormal and flash
Warn；Simultaneously with interrupt mode and levels network service.Program circuit is as shown in Figures 4 and 5.Warning has
Both of which: 1. contact temperature exceedes certain environment temperature；2. contact temperature rise exceedes necessarily within a certain period of time
Temperature.
Although specifically show and describe this utility model in conjunction with preferred embodiment, but the technology of art
Personnel should be understood that in the spirit and scope of the present utility model limited without departing from appended claims,
This utility model can be made a variety of changes in the form and details, be protection model of the present utility model
Enclose.
