Abstract

The utility model discloses a computerized air conditioner controller, which comprises a main control circuit, a command input circuit, a memory, a controlling and executive circuit, and an operating state displaying circuit, wherein, the memory of the computerized air conditioner controller adopts a non-volatile memory which can read and write for multiple times, so that the controller can still memorize parameters in a current operating state in a power-off state. The utility model has the advantages that the controller can automatically drive an air conditioner when powered again after power is off, and use and management are convenient.

Description

The micro computer air-conditioner controller

Utility model relates to household appliance technical field, relates in particular to a kind of micro computer air-conditioner controller with outage self-recovering function.

In the prior art, the controller that is used for air-conditioning does not often have the power loss recovery function, promptly when outage, current all running status state parameters can't be noted, so when sending a telegram here again, air-conditioner can not return the duty before the outage automatically, can only run on holding state, must after manually-operated, just can rerun.Above-mentioned characteristic needs the air-conditioner long-time running to machine room, electric room, public place etc., but often exists the possible occasion of power failure to use and manage air-conditioner and bring a lot of inconvenience.

The purpose of this utility model is: a kind of air-conditioning microcomputer controller with storage running state parameter function is provided, it can note operational factor at that time automatically when air-conditioner cuts off the power supply, automatically according to preservation driving parameter air-conditioner, has the advantage of use, convenient management after waiting to re-power.

The purpose of this utility model is achieved by the following technical solution: a kind of micro computer air-conditioner controller comprises main control circuit, command input circuit, memory, control executive circuit, running status display circuit; It is characterized in that memory adopts the nonvolatile storage that can repeatedly read and write, make this controller when outage, can store current running state parameter automatically.

Aforesaid micro computer air-conditioner controller of the present utility model, the memory that it adopted has the characteristic of the current state parameter of memory air-conditioner operation, can automatically restore to the preceding duty of outage when it is powered on once more after outage, also have the advantage of use, convenient management simultaneously.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is a circuit block diagram of the present utility model;

Fig. 2 is a main program flow chart of the present utility model;

Fig. 3 is a subroutine flow chart of the present utility model;

Fig. 4 is an application circuit detail drawing of the present utility model.

As shown in Figure 1 and Figure 4, micro computer air-conditioner controller of the present utility model comprises main control circuit 1, command input circuit, memory 5, control executive circuit 4, running status display circuit 6; Wherein, memory 5 adopts the nonvolatile storage that can repeatedly read and write, makes this controller can store current running state parameter automatically when outage; Command input circuit comprises key commands input circuit 2 and infrared command receiving circuit 3.Key commands input circuit 2, infrared command receiving circuit 3 pass to main control circuit 1 to its command information that receives from the outside, after main control circuit is handled the information that is received, drive control executive circuit 4 and make corresponding actions, also drive simultaneously display circuit 6 and show current running status, and current running state parameter is existed in the memory 5.

Control executive circuit (4) in the micro computer air-conditioner controller of the present utility model comprises command signal amplifying circuit and command execution circuit, and wherein the command execution circuit is made up of relay part, buzzer and executing agency again.

Running status display circuit (6) in the micro computer air-conditioner controller of the present utility model can be made up of LED, LCD or VFD display and peripheral circuit.

Memory (5) in the micro computer air-conditioner controller of the present utility model adopts E ²PROM or FRAM memory.

As shown in Figures 2 and 3, micro computer air-conditioner controller of the present utility model, in the air-conditioner running, run into when powering on once more after the situation of outage, main control circuit 1 at first carries out power-up initializing to it, then from memory 5, read the control data of running status before the power down, carry out three minutes time-delay command process then, finally run in the control major cycle process.Wherein, the subprogram flow process is: judge at first to have or not button and the infrared order that receives, then do not return if having that then reading order parameter is arranged, and carrying out command process in institute's read command parameter write memory, return at last and constantly circular wait newer command input.
