Description

A kind of centralized-control type electric controller that has the IrDA interface

[technical field]

The utility model relates to the centralized-control type electric controller, and more particularly it is to adopt microcontroller and digital temperature sensor technology, accomplishes the control to electrothermal mechanism, realizes the control device of heating automatically and insulation.

[background technology]

There is following deficiency in the electric controller that generally adopts at present:

1, do not adopt the digital temperature sensor technology, the temperature signal precision is not high.

2, do not possess feedback control function, can not realize preservation and controlling.

3, do not adopt the microcontroller technology, controller is intelligent not strong.

4, the integrated control functions that does not have timing, heat-insulating integral.

For addressing the above problem, it is 201020144351.7 that the applicant has proposed the patent No., and name is called a kind of intelligent electric controller patented claim; And in Granted publication on October 20th, 2010, this controller can overcome the deficiency of above-mentioned prior art, and providing a kind of is the basis with the embedded system technology; Have self-timing heating and preservation and controlling, control accuracy is higher, good reliability; Practical, simple in structure intelligent electric controller.

Though can realize self-timing heating and preservation and controlling through the intelligent electric controller after the applicant's improvement, owing to do not possess wireless communication capability, and install LCD display additional, cost is higher, can not satisfy the low-cost demand that moves centralized control system of user.

[utility model content]

The purpose of the utility model solves the problems of the prior art exactly, proposes a kind of centralized-control type electric controller that has the IrDA interface, can possess the wireless data exchange ability, satisfies the demand of the low-cost collection of user's liquidation keyholed back plate reason, and can reduce cost.

For realizing above-mentioned purpose; The utility model provides a kind of centralized-control type electric controller of the IrDA of having interface; Comprise control circuit, IrDA interface circuit, digital temperature sensor and relay circuit, said control circuit input end is connected with digital temperature sensor, and the control circuit output terminal is connected with relay circuit; Be connected with the IrDA interface circuit on the said control circuit, IrDA interface circuit and upload control host communication.

As preferably, said control circuit is made up of microcontroller, and circuit is simple, and cost is low.

As preferably, said microcontroller adopts the 80C51 chip, and circuit is simple, and cost is low.

As preferably, said IrDA interface circuit is made up of the IrDA integrated circuit, and circuit is simple, and cost is low.

As preferably, said IrDA integrated circuit adopts the TFDS4500 chip, and circuit is simple, and cost is low.

As preferably, said digital temperature sensor is made up of the thermometric integrated circuit, and circuit is simple, and cost is low.

As preferably, said thermometric integrated circuit adopts the DS18B20 chip, and circuit is simple, and cost is low.

The beneficial effect of the utility model: the utility model can be accomplished the heating that is heated object and the control function of insulation; Simple in structure, cost is lower, and controllability is good; Practical; Control accuracy is higher, and possesses the wireless data exchange ability, is convenient to the low-cost collection of user's liquidation keyholed back plate reason; Be applicable to the multiple occasion that heat tracing centralized control demand is arranged, being particularly useful for hospital, kindergarten, the home for the aged, low temp operation etc. has the occasion of demand to controlling warm clothing, food and other article.

Characteristic of the utility model and advantage will combine accompanying drawing to be elaborated through embodiment.

Fig. 2 is the circuit theory diagrams of the centralized-control type electric controller of a kind of IrDA of having interface of the utility model.

[embodiment]

As shown in Figure 1, have the centralized-control type electric controller of IrDA interface, comprise control circuit 1, IrDA interface circuit 2, digital temperature sensor 3 and relay circuit 4; Said control circuit 1 input end is connected with digital temperature sensor 3; Control circuit 1 output terminal is connected with relay circuit 4, is connected with IrDA interface circuit 2 on the said control circuit 1, IrDA interface circuit 2 and upload control host communication; The key distinction of this centralized-control type electric controller and intelligent electric controller is: intelligent electric controller is that each chip itself has control function separately; And the centralized-control type electric controller is controlled by up machine is unified, and it is just passable that each controller only need be carried out dependent instruction, and each controller does not need to establish separately display; Not only control convenient, fastly, and reduced cost.

As shown in Figure 2, control circuit 1 reads in the temperature information that is heated object through its microcontroller 80C51 and the input end that digital temperature sensor 3DS18B20 is connected, and determines whether to heat or stop heating operation according to the program of microcontroller inside; Digital temperature sensor 3DS18B20 accepts the signal from hygrosensor spare, converts numerical information to, sends microcontroller to; When temperature is lower than setting value, microcontroller is in the automatic heat preserving state, then directly carries out heating operation; When temperature is lower than setting value, microcontroller is in regularly heated condition, then need wait for and carry out heating operation when timing condition possesses; When temperature is higher than setting value, microcontroller stops heating operation control; The switch of relay is used to control the on/off of electrothermal mechanism, realizes the work of electrical heating operation or stops; The control that microcontroller 80C51 accomplishes heating automatically and stops to heat the switching manipulation of relay circuit 4 through I/O mouth P1.0, thus realize heating automatically and the control function that is incubated.Control circuit 1 carries out radio communication through the IrDA interface, can accept external command information, carries out corresponding information management.Adopt single power supply Vcc, direct current+5V in the utility model.

The foregoing description is the explanation to the utility model, is not the qualification to the utility model, any protection domain that scheme after the utility model simple transformation is all belonged to the utility model.
