The beneficial effects of the utility model are: the utility model adopts digital temperature sensor to carry out temperature detection, and according to the duty of feedback result control heater, realize the accurate control to the operating temperature in reactor.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Brief description of the drawings
Fig. 1 is the utility model system block diagram.
Detailed description of the invention
The present embodiment is the utility model preferred embodiment, and other all its principles are identical with the present embodiment or approximate with basic structure, all within the utility model protection domain.
Please refer to accompanying drawing 1, the utility model mainly comprises single-chip microcomputer, digital temperature sensor, heater and heating controller, single-chip microcomputer is core parts of the present utility model, whole system is played to control action, digital temperature sensor is for detection of the temperature in light-sensitive surface reactor, and in the present embodiment, digital temperature sensor can arrange one or more, temperature to the multiple points in reactor detects simultaneously, and testing result is fed back to single-chip microcomputer.Single-chip microcomputer output control signal is to heating controller, and the work of heating controller control heater, in the present embodiment, heating controller adopts frequency converter to realize, the dutycycle of Inverter Based on Single Chip Microcomputer output, thereby operating efficiency that can control heater, so that it is operated in optimum state.In the present embodiment, heater adopt electric heater, external power supply inputs to heating controller, by heating controller again out-put supply to heater.
In the present embodiment, on single-chip microcomputer, be connected with off-limit alarm device, in SCM program, be provided with temperature threshold, the temperature detecting when digital temperature sensor higher than set temperature threshold time, illustrate that possibility heating controller or heater damage, now, MCU driving off-limit alarm device is reported to the police.In the present embodiment, between external power supply and heating controller, be also connected with relay, the temperature detecting when digital temperature sensor higher than set temperature threshold time, MCU driving relay disconnects, give by force heater power-off, in order to avoid reactor is caused to damage because of excess Temperature.In the present embodiment, also be provided with refrigerator and refrigeration controler, the work of Single-chip Controlling refrigeration controler, refrigeration controler out-put supply is to refrigerator, the work of control refrigerator, in the present embodiment, refrigeration controler is also connected on same relay, in the time that heating controller is connected on the normally opened contact of relay, refrigeration controler is connected on the normally-closed contact of relay, in the time that heating controller is connected on the normally-closed contact of relay, refrigeration controler is connected on the normally opened contact of relay, in the time that reactor temperature is too high, heater power-off simultaneously refrigerator powers on, so that reactor is played a protective role.
In the present embodiment, on single-chip microcomputer, be also connected with display screen and keyboard, can carry out parameter input by keyboard and arrange, by display screen, duty is shown in real time simultaneously.When concrete enforcement, also can directly adopt touch-screen to replace display screen and keyboard.
The utility model adopts digital temperature sensor to carry out temperature detection, and according to the duty of feedback result control heater, realizes the accurate control to the operating temperature in reactor.
