A driving signal anti-collision protection device, air conditioning system and control method

Abstract

The invention discloses a drive signal anti-collision protection device, an air conditioner system and a control method. The device comprises a main chip (100), a protection circuit (200) and a drive circuit (300). The main chip (100) is configured to send a drive signal to the drive circuit (300). The protection circuit (200) is connected to the main chip (100) and the drive circuit (300). The protection circuit is configured to judge the states of drive signals, and when the state judgment result includes effective drive signals, one path of the effective drive signal is selected and output to the drive circuit (300) to be used for preventing the drive signals from collision. The drive circuit (300) is configured to drive the corresponding load based on the path of the selected effective drive signal. By the adoption of the scheme, the defects that in the prior art, antijamming capacity is weak, the response speed is low and the reliability is poor can be overcome, and the beneficial effects that the antijamming capacity is high, the response speed is high, and the reliability is high are achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular, to a driving signal anti-collision protection device, an air-conditioning system and a control method, and in particular to an air-conditioning two-way solenoid valve anti-collision hardware protection device and an air conditioning system. Background technique [0002] As a kind of air conditioning equipment, air conditioner has gradually become a necessity of people's daily life. Generally, the air conditioning system can be controlled by the cooperation of the solenoid valve and the compressor to realize air conditioning. like figure 1 As shown, an air conditioning system includes a control switch K, a first compressor solenoid valve, a second compressor solenoid valve and a compressor (for example, the model is F518). Among them, two solenoid valves (for example: the first compressor solenoid valve and the second compressor solenoid valve) are designed, and when they...

Problems solved by technology

However, if there are other interference signals, the two solenoid valves may be turned on at the same time; moreover, the response speed of software protection will be much slower than the dynamic response speed of hardware protection.

[0004] In the existing technology, there are defects such as weak anti-interference ability, slow response speed and poor reliability
