Component temperature is too high the problems such as dielectric strength may be caused to decline or burns out equipment；In more humid region, wet gas one
Denier enters and is difficult to discharge, due to inside and outside switch cubicle, the humiture difference of cabinet likely result in the generation of dew condensation phenomenon so that
Cause the corrosion of electrical equipment, so as to insulating capacity can be caused to decline, and influence its mechanically and electrically performance, not only result in through
Ji loss is outer, in some instances it may even be possible to insulating part surface can be caused to produce creepage phenomenon and flashover and initiation accident.
In sum, the research of the real-time monitoring system of high-tension switch cabinet humiture for finding and treatment may be by time
Accident that is too high in humiture and causing has great function, for the treatment in time of the switch cubicle beyond Threshold of Temperature And Humidity and maintenance,
Exclusion is likely to occur the possibility of dangerous and major accident, has both reduced the workload of maintainer, also makes the safety fortune of power network
Row is provided and ensured.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.
As shown in Figures 1 to 5, a kind of high-tension switch cabinet temperature-humidity monitoring based on wireless sense network is present embodiments provided
System, specifically includes humiture collection node, Centroid and Surveillance center, the humiture collection node and Centroid it
Between networking is realized by ZigBee technology, between the Centroid and monitoring center pass through Serial Port Transmission data.
The system of the present embodiment uses one-to-many structure, and network uses star topology, and each switch cubicle places multiple biography
Sensor node, a coordinator node（Centroid）Receive monitoring multiple switch by the data that multiple sensor nodes send
The humiture of cabinet.
Each humiture collection node includes single-chip microcomputer M, sensor S, LCD module L and wireless terminal E, by power supply B pairs
Each part of node powers.As shown in figure 1, single-chip microcomputer receives the data of Temperature Humidity Sensor and processed, show on LCD
After showing the numerical value of real time humiture, then wireless chip is sent to by serial ports.Temperature Humidity Sensor uses SHT11, liquid crystal display
Screen carries out information transfer using LCD1602, wireless chip by ZigBee technology.Temperature Humidity Sensor SHT11 is by sensing elements
It is integrated on one piece of micro-circuit board with signal processing circuit, internal temperature sensor and humidity sensor passes analog signal
Pass operational amplifier, then data signal is converted into by the A/D converter of 14, the number demarcated is exported by SCK and DATA line
Word signal, temperature sensor SHT11 can be calibrated before dispatching from the factory in constant humidity or isoperibol towel, and calibration factor storage exists
In calibration register；In measurement process, calibration factor can automatically calibrate the signal from sensor.Single-chip microcomputer gathers humiture
It is preceding that first sensor is initialized, and be communicatively coupled, register is set, it is 12, humidity data to set temperature data
It is 8.The order 0x05 for reading humidity is first sent afterwards, is respectively necessary for necessarily because sensor gathers and process temperature-humidity signal
Time, therefore SHT11 post answer delay 20ms, single-chip microcomputer receives a high position and low level for data, next sends and adopt respectively again
Collect order 0x03, SHT11 the post answer delay 80ms of temperature, the high position and low level of data are next received respectively, receive temperature
After humidity data, because the temperature sensor of gap material PTAT research and development has fabulous linear, can use
Temperature transition is carried out, humidity sensor is capacitive character condensate hygrometric sensing element.Because the relative humidity of gas is in very great Cheng
Temperature is depended on degree, therefore in Relative Humidity Measuring, should as far as possible ensure the sensor of all same humidity of measurement same
Worked at a temperature of one.When testing, should ensure that tested sensor with reference sensor in same temperature.Linear compensation formulaWith temperature-compensating formula
, thus calculating the numerical value of humiture, unit is respectively degree Celsius and relative humidity.Respectively by warm and humid degrees of data on LCD
Face shows.By asynchronous serial communication by humiture data is activation to wireless terminal node.
In the present embodiment, wireless communication section uses ZigBee technology, and terminal and coordinator node are respectively adopted
CC2530 chips, the chip for having downloaded coordinator process serves as telegon, is the Centroid of network, has downloaded terminal node journey
The chip of sequence directly carries out serial communication as the transmitting terminal of radio communication with single-chip microcomputer.Networking process is as follows：Electricity in module
Afterwards, the module for having downloaded coordinator process is responsible for the foundation of network, and PANID is set to 0xFFFF, telegon generate one it is random
The numerical value not repeated with other networks starts building network as network ID.Set up after network and wait the addition of other nodes.Eventually
End module finds the network that can be added after completing initialization, and networking claim frame is sent to telegon after finding network, and request is added
Network.Telegon is received and can receive after claim frame or refuse the request that networks, and is numbered to the node for allowing to network, if net
Network needs the bigger scope of covering, can set router node, constitutes multihop network.Other programs are carried out again after networking success
Execution.
In the present embodiment, the operation of CC2530 chips is based on rotation inquiry operation system, it would be desirable to which the task of execution is entered
Row registration, coding, each task is performed by the call back function of each task in an operating system.Terminal node is by hardware layer
Serial ports function initialization and register, and be added to the task of operating system treatment function in.Single-chip microcomputer is received to be transmitted across
After the data come, sent it in the air by the function for calling wireless data to send, transmission is unsuccessful will to be resend.In way
Symbol A represents antenna, and the application of antenna causes that the scope of radio communication is bigger, in hgher efficiency.Telegon needs to call serial ports to send out
The function of data is sent, once telegon receives wireless data packet, data buffering area is stored in, serial ports is by the data is activation of buffering area
To computer, that is, complete whole communication process of the warm and humid degrees of data from single-chip microcomputer to computer.
In the present embodiment, in coordinator node（Centroid）After receiving data, computer is sent to by serial ports,
By PL2303 chips by serial data format conversion be USB format.Data can be shown in computer, preserved, be processed.
In examples detailed above implementation, using wireless sensor technology, the information that humiture collection module is gathered is by wireless
Communication mode is sent to monitoring center so that the setting of humiture collection node becomes flexible, eliminates the trouble of wiring.
It is noted that the utility model protection is hardware configuration, do not required as control method communication means etc.
Protection.These are only in the utility model embodiment a preferably embodiment.But, the utility model is not limited to above-mentioned
Embodiment, all any impartial changes done by the utility model scheme and modification, produced function is without departing from this
During the scope of scheme, protection domain of the present utility model is belonged to.
