Method for solving turnout control conflict of interlocking system

The invention discloses a method for solving turnout control conflicts of an interlocking system, which relates to the technical field of urban rail transit, and comprises the following steps: an upper computer module sends turnout control commands to a lower computer module, and the turnout control commands comprise a turnout route operation control command and a turnout single operation control command; a turnout route expropriation code bit is arranged in the lower computer module, and when the lower computer module receives the turnout route operation control command of the upper computer module and the corresponding turnout control command inspection condition is met, the turnout route expropriation code bit is set to be effective; and the turnout control command of the lower computer module is set to check the route expropriation code bit of the turnout to be in an invalid state. By means of the method and device, it is guaranteed that when the turnout rotates towards the specified position of the route
