Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention.
[0023] refer to figure 2 As shown in , the normal conversion of the ZYJ7+SH6 AC hydraulic turnout on the railway is divided into five stages, namely: starting, unlocking, switching, locking and restoration. The current curve acquisition module of the turnout 1DQJ relay starts to record the current Curve, after the 1DQJ relay falls, the monitoring completes the curve record.
[0024] ⑴Start: 1DQJ relay excitation picks up, 2DQJ polarity maintaining relay turns poles, 1DQJF relay excitation picks up, about 380V power supply is sent to the three-phase AC motor to make the three-phase AC motor rotate, the curve at this stage is as follows figure 2 Part ①.
[0025] ⑵Unlocking: Taking the fixed operation as an example, after the three-phase AC motor starts successfully, the three-phase AC motor drives the oil pu...

The invention provides a railway turnout switching process analyzing and assessing system. The railway turnout switching process analyzing and assessing system comprises a current curve collection module, a voltage curve collection module, a power curve collection module, a central processing module and a state display module. The requirement that traditionally, the process and result can be artificially identified by requiring experienced maintenance personnel is reduced to the requirement for the skill that a user only needs to be able to browse and analyze data, general maintenance personnel can learn the skill only through simple training, and the cost for training turnout data analysis personnel is reduced. In the turnout switching processes, the normal, abnormal and fault states of each process are accurate to the state of a certain one of unlocking, switching and locking processes of the curves of each turnout, the judgment precision is improved, and precise maintenance is facilitated. Manpower is saved, and the labor intensity is reduced.
Description
technical field [0001] It relates to the technical field of safety monitoring of railway turnouts, in particular to the improvement of health state monitoring during the conversion process of ZYJ7 type turnouts. Background technique [0002] The ZYJ7 turnout on the railway, also known as "speed-up turnout", is a type of turnout widely used in Chinese railways. The electrical affairs departments such as the railway electrical affairs department, the electrical affairs department, and the electrical affairs section are mainly responsible for the switching and operation of turnouts, and the railway engineering department is responsible for the rail part on the line. In order to reduce the occurrence of turnout failures and analyze the state of turnouts in advance, in recent years, some electric power depots and electric power workshops have also set up "analysis rooms". Organizing experienced maintenance personnel to conduct manual analysis has high labor costs. [0003] The ...
