[0080] Please see Figure 5 , the third embodiment of the present invention provides a control method for a relay control module, and the method is applied to the relay control module in the first embodiment. The following will be Figure 5 As illustrated in the flow chart, the method includes:

[0081] Step S110: the communication module receives control parameters.

[0082] Step S120: the input component collects signal data.

[0083] Step S130: the microprocessor judges whether the signal data satisfies a preset condition.

[0084] Step S140: When the preset condition is satisfied, the microprocessor drives the relay and the terminal device connected to the output component to work according to the preset program based on the control parameter.

[0085] The preset program includes: a virtual signal obtained by calculating a logical variable according to a preset logical expression, and the virtual signal is used to control the relay, wherein the logical variable is an i...

Abstract

The present invention provides a relay control module, a control method thereof and a relay control system and relates to the electronic field. The relay control module comprises a microprocessor, a relay, a communication module, an input assembly and an output assembly. The microprocessor is respectively coupled to the relay, the communication module, the input assembly and the output assembly. The communication module is used for receiving and / or sending modifiable control parameters. The input assembly is used for acquiring signal data. The microprocessor is used for storing an encryption algorithm and a secret key matched with the encryption algorithm. The microprocessor is also used for encrypting control parameters based on the encryption algorithm and then sending the control parameters to the communication module, or decrypting the control parameters received by the communication module based on the secret key. The relay control module can alleviate the problem in the prior art that a current relay control module is single in control mode, narrow in application range and unsafe in communication.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a relay control module, its control method and a relay control system. Background technique [0002] The relay (Relay), also known as the relay, is an electronic control device, which has a control system (also known as the input circuit) and a controlled system (also known as the output circuit), usually used in automatic control circuits, and is used in small A kind of "automatic switch" that controls the larger current. The traditional relay integrated control module only controls one or a group of relays each time, and the single control method has a narrow application area, and the communication is not safe. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a relay control module, its control method and a relay control system, so as to alleviate the problems of single control mode, narrow application area a...
