The clamp type non-contact DC and AC collection module is clamped in the operating return wire of a switch control circuit. The output end of the clamp type non-contact DC and AC collection module is connected to the input end of the signal conditioning module. The output end of the signal conditioning module is connected to the input end of the master control module. The output end of the master control module is connected to the display module. The output end of the power supply module is connected to the input end of the master control module. According to the device, the outdoor maintenance operation of the electric staff is facilitated, the efficiency of outdoor switch maintenance and fault processing is improved, the portable switch operating current curve acquisition device has the advantages of small size, convenient carrying, high reliability, strong practicability, easy maintenance, low cost and easy promotion and use.

Description

technical field [0001] The invention relates to an auxiliary device for railway signal monitoring, in particular to a portable switch action current curve acquisition device. Background technique [0002] At present, the monitoring method of the turnout operating current curve of the railway signal centralized monitoring system is: the current of the DC point machine is selected from the sub-distributor or a combination of the operating current return line, and the signal is obtained through the core sampling of the DC current sensor, and the current of the AC point machine Sampling is taken from the output terminal of the open-phase protector, so as to isolate and collect the operating current of the turnout. The acquisition machine for centralized monitoring of railway signals will amplify the sampling signal through operation, precision rectification, operation amplification, signal conditioning, and then send it to the acquisition board of the turnout acquisition machine,...

AI Technical Summary

Problems solved by technology

Therefore, the monitoring technology of the turnout current curve has the following disadvantages: the current sensor is fixed at the rear of the combined frame, and when the station machine issues an order to ask for data, a complete turnout current curve data is sent to the station machine for display. Personnel must check the action current curve of the turnout during maintenance, which can only be read from the station machine, which is not conducive to the outdoor maintenance work of electricians and the improvement of the efficiency of troubleshooting
