Detailed Description
The technical solution, the achieved objects and the effects of the embodiments of the present invention will be described in detail with reference to fig. 1 of the drawings.
The invention provides a method for automatically switching control right of a computer interlocking operating machine, wherein in a computer interlocking system, one operating machine is set as a main operating machine, the other operating machines are set as standby operating machines, and each operating machine is in communication connection with an interlocking lower computer; when each operating machine operates normally, the current control right mode is stored into the text at regular time; or when the control right mode of each operator is changed, the current control right mode is also saved in the text. When the interlocking lower computer is restarted, the method for automatically switching the control right of each operating machine comprises the following steps:

If the interlocking lower computer is not electrified and locked, the operating machine considers that the interlocking lower computer is not restarted, the operating machine does not need to execute automatic switching, current setting is carried out according to the control right mode read from the text in the step S1, and the step SE is entered. If the interlock lower computer has a power-on lock, the process proceeds to step S3.

If the operation machine is a standby operation machine, the process proceeds to step S5.
Step S4, the main operating machine sends the corresponding control right switching message to the interlocking lower computer according to the original control right mode stored for the last time, waits for receiving the feedback message of the interlocking lower computer and switches the control right mode after judging the feedback message, and the method specifically comprises the following steps:
s4-1, the main operating machine sends a corresponding control right switching message to the interlocking lower computer according to the original control right mode (such as self-discipline) information which is stored for the last time, requests to switch the control right mode of the interlocking lower computer to be consistent with the original control right mode which is stored for the last time by the main operating machine, and enters S4-2;
and S4-2, the main operating machine waits for receiving a control right switching feedback message sent by the interlocking lower computer, and if the feedback is not received after overtime or a switching failure message is received, the step S4-3 is carried out. If receiving the switching success message, considering that the automatic switching is successful, and entering step S4-4;
and S4-3, the main operating machine considers that the automatic control right switching of the interlocking lower computer fails, sets the control right mode of the main operating machine as the abnormal control, sends a control right switching ending message to all the standby operating machines, stores the control right mode of the abnormal control into a text, and enters the step SE.
Step S4-4, the main operating machine considers that the interlocking lower computer automatically switches the control right successfully, sets the new control right mode updated by the main operating machine as the original control right mode (such as decentralized autonomous) stored last time, namely, the new control right mode is consistent with the control right mode updated by the interlocking lower computer, sends a control right switching end message to all the standby operating machines, stores the new control right mode (such as decentralized autonomous) updated into the text, and enters step SE.
Step S5, the standby operating machine waits for receiving the control right switching end message sent by the main operating machine, and updates the control right mode, which specifically includes the following steps:
s5-1, the standby operating machine waits for receiving the control right switching end message sent by the main operating machine, and the standby operating machine enters S5-2 when successfully receiving or waiting for overtime;
step S5-2, the standby operating machine sets the control right mode according to the latest control right mode reported by the interlocking lower computer, sets the control right mode of the standby operating machine as the updated new control right mode of the interlocking lower computer, and stores the current control right to the text; step SE is entered.
And step SE, the operating machine establishes communication connection with the external control system in the local control right mode which is updated and set, and the algorithm is ended.
The method for automatically switching the control right of the interlocking manipulator supports the existence of a plurality of control right modes of the manipulator and also supports the simultaneous existence of a plurality of external control system interfaces.

S4-2, the operating machine A waits for receiving a feedback message of a control right switching result sent by the interlocking lower computer C, if the feedback message is not received after overtime or the feedback message of switching failure is received, the interlocking lower computer C is considered to fail to automatically switch the control right mode, and the step S4-3 is entered; and if the switching success message is received, the interlocking lower computer C is considered to be successful in automatically switching the control right mode, and the step S4-4 is entered.
And step S4-3, setting the control right mode of the operating machine A as the abnormal station control, sending a message of ending the control right switching failure to the operating machine B (standby operating machine), simultaneously saving the current control right as the text from the abnormal station control to the operating machine A, and establishing communication connection with the station unit control console system 2 and the automatic train monitoring system 3 by the abnormal station control.
And the operating machine B (standby operating machine) sets the local control right mode for the abnormal station control according to the control right mode newly reported by the interlocking lower computer C, namely the control right mode of the operating machine B is also set to be the abnormal station control, and the algorithm is ended.
