Document Type and Number:
WIPO Patent Application WO/2024/094140
Kind Code:
A1
Abstract:
A remote measurement and control terminal and a safety control system are provided. The terminal comprises: an interface module and processing modules; each processing module comprises an I/O channel unit and a controller, and each I/O channel unit comprises an analog quantity interface unit; the analog quantity interface unit comprises a signal switching unit and a first switch unit; an input end of the first switch unit is connected to the interface module and is used for accessing a first analog signal that is externally inputted, and an output end of the first switch unit is used for sending the first analog signal to a first input end and a second input end of the controller; the signal switching unit is used for controlling the first switch unit to be disconnected when a first control signal outputted by the controller is received, for generating a second analog signal when a second control signal outputted by the controller is received, and for sending the second analog signal to the first input end and the second input end of the controller. The remote measurement and control terminal effectively improves signal transmission safety and reliability.
