The present invention relates to a kind of water temperature control device, be specifically related to a kind of monolithic processor controlled water temperature control device.
Background technology:
Temperature is one of technological parameter common in the commercial production, and any physical change and chemical reaction process are all closely related with temperature, so temperature control is the vital task of the production automation.For the control of the temperature under the different conditions of production and the technological requirement, the type of heating that is adopted, fuel, controlling schemes is also different.Present solar water heater uses water temperature regulater mostly, but present water temperature regulater cost height, sensitivity are low, purposes has certain limitation.
Summary of the invention:
The purpose of this invention is to provide a kind of monolithic processor controlled water temperature control device, it can set control water temperature in 40-90 ℃ of scope, static control accuracy is 0.2 ℃, and has rapidity and less overshoot preferably, and function such as the demonstration of decimal system number pipe, temperature curve printing, system is less demanding to control accuracy, and the linearity of heating and cooling process is not required yet.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is by single-chip microcomputer 1, temperature indicator 2, keyboard 3, alarm 4, A/D converter 5, transmitter 6, temperature sensor 7, optocoupler 8, driver 9, controllable silicon oscillator 10 and circuit 11 are formed, single-chip microcomputer 1 is connected with temperature indicator 2, keyboard 3 is connected to single-chip microcomputer 1, single-chip microcomputer 1 is connected with alarm 4, temperature sensor 7 and transmitter 6, transmitter 6 and A/D converter 5, A/D converter 5 and single-chip microcomputer 1, single-chip microcomputer 1 is connected with optocoupler 8, optocoupler 8 is connected with driver 9, and driver 9 is connected with controllable silicon oscillator 10, and controllable silicon oscillator 10 is connected with electric furnace 11.
The present invention is a typical closed-loop control system, real-time parameter is gathered in real time by sensor and A/D converter 5 in the operational process, and by microcomputer write down automatically, statistical table making, and then by parallel interface output control signal, the control executing mechanism action is regulated and is controlled.System is less demanding to control accuracy, linearity to heating and cooling process does not require yet, therefore, system adopts the simplest break-make control mode, promptly when the drying baker temperature reaches setting value, disconnect and add electrothermal stove 11, connect electric furnace 11 when being lower than certain value and begin heating when temperature drops to, thereby keep thermostatic control.It is core parts that the present invention adopts single-chip microcomputer, and system control scheme is simple, and data volume is also little.
