The technical scheme that the utility model adopts is following:
Digital temperature-humidity sensor is installed in batch meter; The signal of digital temperature-humidity sensor is connected to single-chip microcomputer, and the output of single-chip microcomputer is connected to warning device, LCD display, and the output of single-chip microcomputer is connected to cooling driving circuit and heat sink successively; The output of single-chip microcomputer is connected to remove successively reveals driving circuit and removes the dew device; Keyboard is connected with single-chip microcomputer, is used for the input of definite value, and single-chip microcomputer is connected with distance host through communication interface.
Further, described heat sink is fan or air-conditioning.
Further, described is the combination of well heater or well heater and fan except that revealing device.
Preferably, described communication interface is the RS485 interface.
The utlity model has following good technique effect:
Adopt a kind of electric metering box temperature and humidity monitor device of present embodiment; Can detect electric metering box humiture situation in real time; When the output signal of Temperature Humidity Sensor, when promptly temperature or humidity value transfinite, there is single-chip microcomputer to send control signal; Through corresponding driving circuit starting fan automatic heat radiation or starting well heater and exhaust fan dehumidifying, to prevent the generation of device of overheating of electrical and condensation.Simultaneously, device also has warning function, Presentation Function, through communication interface, and then can realize the communication upload function.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Accompanying drawing 1 is the theory diagram of an embodiment of the utility model;
Accompanying drawing 2 is the circuit diagram of an embodiment being connected with single-chip microcomputer of the utility model Temperature Humidity Sensor.
Embodiment
Referring to accompanying drawing 1, it is a kind of embodiment of electric metering box temperature and humidity monitor device.
Digital temperature-humidity sensor is installed in batch meter, a plurality of digital temperature-humidity sensors is installed, can the monitoring and metering case in multi-point temp and humidity, the signal of digital temperature-humidity sensor is connected to single-chip microcomputer.
The Temperature Humidity Sensor of conventional analogue formula generally all needs the modelled signal modulate circuit, and needs through complicated calibration and calibration process, so measuring accuracy is difficult to guarantee, and often unsatisfactory aspect the linearity, repeatability, interchangeability, consistance.The accurate digital relative Temperature Humidity Sensor SHT11 of the whole school that present embodiment selects for use Switzerland Sensirion company to produce with I2C EBI.
The SHT11 Temperature Humidity Sensor can be directly through the I2C bus with the microprocessor of any kind, for controller is connected, such as the AT89S52 single-chip microcomputer, thereby reduced the cost of interface circuit, simplified interface mode.Fig. 2 shows the SHT11 Temperature Humidity Sensor and is connected with the circuit of AT89S52 single-chip microcomputer.
Referring to accompanying drawing 1 embodiment, the output of single-chip microcomputer is connected to warning device, LCD display, and when temperature or humidity value transfinited, device produced alerting signal, but and LCD display show fault type and relevant data.LCD display can adopt 12864M Chinese character image dot matrix lcd module, can display graphics and Chinese character.
Referring to accompanying drawing 1 embodiment, the output of single-chip microcomputer is connected to cooling driving circuit and heat sink successively, and the output of single-chip microcomputer is connected to remove successively reveals driving circuit and remove the dew device.When monitor temperature transfinites, there is single-chip microcomputer to send control signal, the output of single-chip microcomputer is connected to the cooling driving circuit, and cooling driving circuit starting fan or air-conditioning automatic heat radiation are to prevent the generation of device of overheating of electrical.When monitoring humidity value when transfiniting, there is single-chip microcomputer to send control signal, the output of single-chip microcomputer is connected to remove reveals driving circuit, removes the combination of revealing driving circuit starting well heater or well heater and fan and dehumidifies, to prevent the generation of electrical equipment condensation.
Driving circuit drives the work and the shutdown of relevant device through the relay circuit of a band of the I/O interface starting triode switch of single-chip microcomputer through the switch of relay.
Present embodiment is selected the pectination aluminium alloy electric well heater that aims at the moistureproof dehumidification design of power equipment for use, and it is to be processed by resistive heater and pectination aluminium alloy heat sink.
Referring to accompanying drawing 1 embodiment, keyboard is connected with single-chip microcomputer, is used for the input of definite value, such as the numerical value of the size and the humidity of temperature, and other definite value.
Unexpected except satisfying local warning and demonstration for humiture, in order to realize the monitoring of a distant place for the humiture in the batch meter, single-chip microcomputer is connected with distance host through communication interface, can realize long-range monitoring and control.
Because the RS232 serial communication interface of general single-chip microcomputer outfit standard, its coverage has only tens meters, has satisfied not the requirement of electric power system communication.Present embodiment has disposed the RS485 interface that a communication distance maximum can reach 1.2Km, adopts the MAX485 converter, is the RS485 signal with the RS232 conversion of signals.
