Abstract

The invention discloses a high-safety programmable control switch controller, and the controller comprises a control module, a communication module, an electromagnetic relay module, and a drive module. The control module stores an input end code set initially or according to a control side command. The control module receives a starting instruction and a modification instruction which are sent by a control side and comprise the input end code, and enables the input end code received from the control side to be matched with an input end code stored locally. If the matching is successful, a starting instruction is executed, and the password modification instruction is executed. A new input end code transmitted by the control side is received to replace an original input end code stored locally. The controller can modify the input end code while being started each time, and the input end code can be randomly generated by operation equipment of the control side, and is very high in security. According to the invention, the communication module is provided with a filter, and the filter directly carries out the filtering of high-speed code scanning input, thereby preventing a person from carrying out code scanning at a high speed at an input end and cracking a password.

Description

technical field [0001] The invention relates to the field of programmable relay control, in particular to a high-safety programmable control switch controller. Background technique [0002] At present, the input signal of the programmable relay is a high and low level signal in a fixed format that can be set and known by the operator, and the output is a passive contact of the relay. The input terminal code of this programmable relay is a fixed format of high and low levels, and the input terminal code signal of the relay can be obtained by scanning the input terminal code or consulting the technical manual, so that it is very easy to be controlled by illegal personnel other than the operator. output. This kind of relay cannot realize the purpose of preventing artificial cracking of codes and maliciously controlling relay output for use occasions that have a certain confidentiality and cannot be controlled by people at will. Contents of the invention [0003] The technic...
