Description

technical field [0001] The present application relates to the field of signal machine safety in rail transit, in particular to a wireless monitoring system and method for signal machines. Background technique [0002] As an important part of railway signals, equipment such as signal machines and switch machines have been widely used in the field of rail transit. The health of these equipment will directly affect the safety of vehicle operation. Therefore, in order to increase the reliability of equipment work, the development and application of corresponding equipment monitoring modules have also been valued by people in the industry. In China, most of the monitoring products for railway signal products such as signal machines and switch machines are based on RS485, Wired transmission methods such as CAN or optical fiber transmission. [0003] Since the devices using CAN and RS485 communication need to be connected by cables, the cable laying scheme and cost need to be cons...
