Embodiment 1

[0026] figure 1 is a flowchart of an automatic error correction control method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0027] Step S101, setting the first preset clock as the working clock to control the operation of the load;

[0028] Step S102, triggering the interrupt operation after each preset interrupt duration, and starting the timing operation according to the second preset clock, and then controlling the load to continue running;

[0029] Step S103, when the next interrupt operation is triggered, obtain the timing time monitored by the timing operation;

[0030] Step S104, determining whether the system clock of the control chip is abnormal according to the timing time and the preset interrupt duration.

[0031] This embodiment provides a safe and controllable automatic error correction control scheme, which can effectively monitor whether the system clock of the control chip is norm...

Embodiment 2

[0036] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. figure 2 is an automatic error correction control flow chart of the air conditioner according to an embodiment of the present invention, such as figure 2 As shown, the process includes:

[0037] Step 1: The air conditioner control chip starts to work.

[0038] Step 2: The air conditioner control chip executes the initialization program, and provides the original clock source to each functional module inside the control chip after frequency multiplication and frequency division as a working clock. Set the timing T (that is, the above-mentioned preset interrupt duration), that is, execute the interrupt subroutine every interval T.

[0039] Step 3: Run the system program according to the working clock set in Step 2 to control the operation of the air conditioner load.

[0040] Step 4: Determine whether to trigger t...

Embodiment 3

[0050] corresponds to figure 1 The automatic error correction control method introduced, this embodiment provides an automatic error correction control device, such as image 3 The structural block diagram of the automatic error correction control device shown, the device includes:

[0051] The control chip is used to set the first preset clock as the working clock to control the operation of the load; it is also used to trigger the interrupt operation after each preset interrupt duration;

[0052] The clock monitoring timer is used to start the timing operation according to the second preset clock when the control chip triggers the interrupt operation;

[0053] The processor is used to acquire the timing time monitored by the clock monitoring timer between two interrupt operations, and determine whether the system clock of the control chip is abnormal according to the timing time and the preset interrupt duration.

[0054] This embodiment provides a safe and controllable au...

Abstract

The invention discloses an automatic error correcting control method and device and electrical equipment. The method comprises the following steps of setting a first preset clock as a working clock, and controlling operation of the load; triggering interruption operation every time after a preset interruption duration is operated, starting timing operation according to a second preset clock, and then controlling the load to continuously operate; obtaining the timed time monitored by timing operation when next interruption operation is triggered; and determining whether a system clock of a control chip is abnormal or not according to the timed time and the preset interruption duration. By means of the method, whether the system clock of the control chip is normal or not can be effectively monitored, in regard to the situation that abnormal strong interference is applied to the electrical equipment in operation, the clock of the control chip of the equipment is disordered, so that the electrical equipment operates in an out of control mode, timely controllable safe shutdown restarting can be realized, potential safety hazards are eliminated, the anti- interference capability of the product is improved, and the product safety is improved.

Description

technical field [0001] The invention relates to the field of unit technology, in particular to an automatic error correction control method, device and electrical equipment. Background technique [0002] The existing air-conditioning control technology can well meet the requirements of the lightning surge immunity standard (the highest international standard is 4kV), and has successfully passed the certification. However, once the product is disturbed far beyond the standard level, such as a 10kV surge voltage, it may cause the air conditioner to run out of control, posing certain safety risks. [0003] Aiming at the problem of out-of-control operation of equipment caused by lightning surge in the prior art, no effective solution has been proposed so far. Contents of the invention [0004] Embodiments of the present invention provide an automatic error correction control method, device, and electrical equipment to solve the problem of out-of-control operation of equipment...
