Problems solved by technology
The current turnout control interface circuit adopts different stereotyped relay combinations according to different interface systems, and the relay adopts a gravity type relay. The disadvantages of the above method are: (1) the gravity type relay is large in size, high in cost, and takes up a large space; 2) Gravity-type relays have a short service life and require regular maintenance by professional organizations. Except for China National Railway, other application units have no such maintenance capabilities, which seriously restricts the entry of Chinese signal products into the international market.
However, the above-mentioned structure also has defects such as high cost and poor versatility.

Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a phase failure detection module of a three-phase turnout switch machine and a method for using the same. Background technique [0002] At present, the turnout control interface circuits used in our country are divided into: 4-wire control circuit, 5-wire control circuit, and 6-wire control circuit. The current turnout control interface circuit adopts different stereotyped relay combinations according to different interface systems, and the relay adopts a gravity type relay. The disadvantages of the above method are: (1) the gravity type relay is large in size, high in cost, and takes up a large space; 2) Gravity-type relays have a short service life and require regular maintenance by professional organizations. Except for China National Railway, other application units have no such maintenance capabilities, which seriously restricts the entry of Chinese signal products into...
