[embodiment]
See also Fig. 1 to 4, the remote temperature measurement and control protective device with warning function comprises power supply, temperature detecting module, display module, central processing module, Executive Module.
Central processing module adopts single-chip microcomputer and auxiliary circuit, determines the core as system with the AT8051 of ATMEL, the 11.0592MHz dominant frequency.As a kind of intelligence system, its core is at microprocessor; 8051 series microprocessors are one of microprocessors that are most widely used in China at present, and its licensed-type production producer is more, have domesticly also obtained the INTER mandate as Shenzhen macrocrystalline company.More similar 8 single-chip microcomputers of performance and price have its advantage; It is also more to develop software.Central processing module also is provided with network interface, can carry out network and connect, and uses a computer and directly controls, analyzes.Central processing module also connects a security parameter circuit is set, and security parameter is provided with the outage operating temperature that circuit is used to alarm temperature is set and is higher than alarm temperature, and selected numerical value is inputed to central processing module.Central processing module has a plurality of data input pins (the 1-7 pin of MCU), can multichannel laying temperature transducer.
Central processing module connects a data recordin module, and this data recordin module always writing circuit cuts off the temperature value of scope for the previous period.Data recordin module uses ATMEL2416 serial EEPROM storage temperature.The temperature data that detection is obtained leaves in the serial EEPROM.The space 2K of ATMEL2416EEPROM can deposit 2000 temperature datas approximately.Can machine-readablely go out with calculating by network interface, be used to analyze motor (transformer) work temperature rising state.Played the effect of " black box ".
The 1-wire digital temperature sensor DS18B20 that temperature detecting module selects for use U.S. DALLAS company to produce.DS18B20 can be directly changed into serial digital signal to temperature signal and handle for single-chip microcomputer.Because every DS1820 contains unique silicon serial number, so on a bus, can articulate many arbitrarily DS18B20 chips.Information of reading from DS18B20 or the information of writing DS18B20 only need a mouth line (one-wire interface).The power supply of read-write and temperature inversion comes from data/address bus, and bus itself can be powered to the DS18B20 that is articulated, and need not additional power supply.DS18B20 provides nine megadyne temperature degree readings, constitutes the multi-point temp detection system and need not any peripheral hardware.One build-out resistor R1 is set in the temperature detecting module, can makes that temperature sensor is long-range to be placed into 150 meters, like this, other modules can be concentrated and be placed on remote control room.
Fig. 4 uses 47 sections red LED to show for showing and power circuit diagram, clear display, and the little life-span of power consumption is long.Power circuit is selected the Switching Power Supply of using MIC4680 switch type voltage stabilizing IC to form for use.Common transformer rectification adds that three-terminal voltage-stabilizing mode efficient is low, caloric value is big.MIC4680 is a 1A pressurizer that is operated in 200KHz, as long as be equipped with capacitor and inductor, fast diode and feedback resistance just can be combined into a voltage stabilizing circuit that volume is extra small.Conversion efficiency that what deserves to be mentioned is MIC4680 is up to 90%, and the non-constant width of input voltage can adapt to the 34V direct current from 6V.The power transformer secondary uses when exchanging 12 volts, and original edge voltage allows fluctuation range to reach and exchanges 90～440 volts, and power supply accommodation is very broad.
Executive Module is connected in the output port of central processing unit, controls its operating state by central processing unit.Executive Module comprises the early warning circuit that is driven by relay and cuts off movement device.The security set circuit is provided with an alarm temperature and is higher than the outage temperature of this alarm temperature, and selected numerical value is inputed to central processing module, and when temperature reached alarm temperature, the early warning circuit relay started, and sends early warning signal; When temperature continuation rising reaches the outage temperature, cut off the work of movement device relay, thus the cut-out circuit, cut-out movement device relay adopts self-latching relay, avoids misoperation.
Control program is set in the central processing unit, the data of input are handled, export corresponding control signal then to Executive Module.Program flow diagram is seen Fig. 5.
Need to prove that the utility model is a kind of remote temperature measurement and control protective device with warning function, in fact, this device can be applied to other control fields, and such as pressure, speed etc., its difference only is the difference of transducer.Liquid crystal display also can be used in the display part, and its difference is only in the difference of display device.Those of ordinary skill in the art can be applied to this device the field that other can be converted to the signal of telecommunication according to indication of the present utility model.
