AI Technical Summary

Problems solved by technology

During the transmission of the control signal by the controller, the control signal changes due to the environmental interference of the transmission channel, and sometimes the change exceeds the operating range of the compressor, resulting in the abnormal operation of the compressor in the existing equipment with a compressor.

Embodiment approach 1

[0063] Embodiment 1: For compressor start-up operation or operation parameter adjustment operation;

Embodiment approach 2

[0064] Embodiment 2: for the shutdown operation of the compressor.

[0065] The specific process of Embodiment 1 includes: the state mapping value is equal to the power-on fixed value, and the frequency control value is within the frequency control range [0, 150] and the acceleration mapping value belongs to the acceleration control subset {1, 2, 3}, then the operation is satisfied. license conditions.

[0066] The specific process of the second embodiment includes: the state mapping value is equal to the shutdown setting value, and the frequency regulation value is 0 and the acceleration mapping value is 1, then the operation permission condition is met.

[0067] Through the above two implementation manners, the control of the compressor is effectively simplified.

[0068] Since the acceleration mapping value is an integer value, the acceleration may be a non-integer value, and the acceleration mapping value can more clearly reflect the acceleration parameter changes caused ...

Abstract

The invention provides a data processing method based on a single chip microcomputer, a driver, a controller and a system. The data processing method based on a single chip microcomputer includes thesteps of setting a running permission condition and receiving a current regulating and controlling indication signal set sent by an external controller; determining whether the current regulating andcontrolling indication signal set satisfies the running permission condition or not, and if the current regulating and controlling indication signal set satisfies the running permission condition, according to the current regulating and controlling indication signal set, regulating and controlling operating parameters of a compressor, otherwise, ignoring the regulating and controlling indication signal set, and waiting for receiving a next regulating and controlling indication signal set. By means of the scheme, the abnormality of the compressor can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a single-chip microcomputer-based data processing method, driver, controller and system. Background technique [0002] For equipment with compressors, such as inverter air conditioners, coal-to-electricity air source heat pumps, etc., it is mainly controlled by the controller and the driver. The controller outputs frequency commands to control the work of the driver. In this control process, it is a key step to correctly enter the process of the driver controlling the compressor. [0003] Generally speaking, in existing equipment with a compressor, when the driver receives the regulation signal sent by the controller, it directly regulates the compressor according to the regulation signal. During the transmission of the control signal by the controller, the control signal changes due to the environmental interference of the transmission channel, and sometimes the chang...
