Abstract
The invention discloses a heating protection system for an electric blanket, which belongs to the technical field of electronics. The heating protection system comprises a power supply and further comprises a microcontroller, a constant temperature display, a constant temperature setting switch, a temperature sensor, a drive circuit, a relay and a heating module, wherein the power supply is electrically connected with the microcontroller, the input ends both of the constant temperature display and the temperature sensor are electrically connected with the output end of the microcontroller, the constant temperature setting switch is connected with the output ends of the heating module and the drive circuit through the input ends of a control circuit and the microcontroller, and the drive circuit is connected with the relay electrically. The heating protection system has the benefits that the temperature can be automatically set, the circuit can be automatically closed without manual operation according to the set temperature, the operation is simple and convenient, the energy sources are saved, and the cost is lowered.
Description
Technical field
The present invention relates to a kind of heated protective system, specifically a kind of electric blanket heated protective system belongs to electronic technology field.
Background technology
Existing electric blanket in the market, major part only has the height temperature control switch, can not arbitrarily control temperature, function ratio is more single, and needs manual control switch's closure, in case forget the pass swap switch, electric blanket will ceaselessly heat, both waste electric energy, and can because of excess Temperature, cause the serious contingency of fire lamp again.
Summary of the invention
For the problem that above-mentioned prior art exists, the invention provides a kind of electric blanket heated protective system, need not the manual control switch, the design temperature of can using by oneself has the function of auto-closing power supply, protection circuit, energy savings reduces cost.
To achieve these goals; the technical solution used in the present invention is: a kind of electric blanket heated protective system; comprise power supply; also comprise microcontroller; the constant temperature display; the constant temperature configuration switch; temperature sensor; drive circuit, relay, heating module; power supply is electrically connected with microcontroller; the input of constant temperature display and temperature sensor is electrically connected with the output of microcontroller, and constant temperature configuration switch and heating module are connected output and are connected with the input of microcontroller by control circuit with drive circuit, and drive circuit is electrically connected with relay.
The invention has the beneficial effects as follows: can set up temperature on their own, and according to the temperature of setting, the auto-closing circuit need not manual operation, and is simple and convenient, and energy savings, reduces cost.
Description of drawings
Fig. 1 is electric theory diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of electric blanket heated protective system comprises power supply; also comprise microcontroller, constant temperature display, constant temperature configuration switch; temperature sensor; drive circuit, relay, heating module; power supply is electrically connected with microcontroller; the input of constant temperature display and temperature sensor is electrically connected with the output of microcontroller, and constant temperature configuration switch and heating module are connected output and are connected with the input of microcontroller by control circuit with drive circuit, and drive circuit is electrically connected with relay.
With the electric blanket plugged, each element is started working in the electric blanket, set the protractor that oneself needs by the constant temperature configuration switch, and send signal to controller, controller passes the signal to constant temperature display and temperature sensor again, temperature indicator demonstrates the temperature of setting, after temperature sensor senses is heated to the temperature of setting to heating module, by control circuit signal is passed to microcontroller, microcontroller is passed to drive circuit, drive circuit drives the relay deenergization, when temperature sensor senses did not reach design temperature to temperature, controller drove relay and works on by drive circuit, plugged is until temperature reaches design temperature.
