and the control module sets the number of the administrator modules for each control area, and selects the administrator modules from the available administrator module resource pool to supplement when one control area lacks the administrator modules.
A sixth embodiment;
the invention provides a control system for dynamically selecting an administrator module, which is used for a train operation control system based on vehicle-to-vehicle communication, and comprises the following components:
the system comprises an administrator module, a monitoring module and a monitoring module, wherein the administrator module determines the administration range according to a control area, is arranged on a train or beside a track, dynamically adjusts the number of the control area between 1 and n according to the number of trains put into operation, n is a natural number greater than 1, and forms hardware redundancy;
the administrator module determines whether the vehicle-mounted administrator module or the trackside administrator module is the administrator module according to the deployment position of the administrator module, and the specific functions of the administrator module can be realized by a computer programming technical means;
the administrator module can manage one or more control areas, and the maximum administration capacity (taking the control area as a unit, for example, at most two main control areas are managed) of the administrator module can be configured off line or can be dynamically determined according to the type of the train managed by the administrator module, the number of the trains and the number of routes arranged;
the number of control areas administered by the administrator module is dynamically adjusted between 1 and the maximum administration capacity n according to the number of trains (operation trains refer to online trains which are provided with ATC equipment and can normally communicate with other equipment) which are put into operation, when the number of the trains put into operation is small, the number of the control areas administered by the administrator module is n, along with the increase of the vehicles put into operation, the administrator module gives up the administration right of a part of control areas (the trains which are newly put into operation are responsible for management) until the number of the control areas administered by the administrator module is 1, and when the number of the vehicles put into operation is reduced, the administrator module takes over the management to quit the control areas administered by the operation trains until the number of the control areas administered by the administrator module reaches the maximum administration capacity n;
the trackside manager module is located in a central control center or a vehicle section control center, and the jurisdiction range of the trackside manager module is a place where trains are stored after operation is finished, such as a vehicle base. The jurisdiction range of the trackside manager module can be dynamically adjusted according to actual conditions, for example, a full-line non-operation train, and when the engineering truck runs on a main line, the jurisdiction range of the engineering truck is expanded to a main line control area where the engineering truck enters a road; and when the engineering vehicle returns to the vehicle base, the trackside manager module gives up the jurisdiction of all the main control areas.
The administrator module can be deployed in a distributed manner in the system, and is deployed beside a rail when being used as a trackside administrator module, and is deployed beside a train when being used as a vehicle-mounted administrator module, as shown in fig. 1;
the vehicle-mounted manager module and the trackside manager module are usually realized by a hardware architecture of two-out-of-three or two-by-two, and have certain redundancy capability, the hardware architecture of two-out-of-three means that the equipment consists of three operation units, and any two operation results in the three units are consistent and represent that the equipment works normally, namely, the operation of the equipment is not influenced by the fault of any one operation unit.
The hardware architecture of two-by-two-out-of-two means that the equipment is composed of a machine A and a machine B, the machine A and the machine B are mutually hot standby, under the condition that the machine A and the machine B are synchronous, any one of the machine A and the machine B fails, the other one of the machine A and the machine B operates normally, and the operation of the whole equipment is not influenced. The hardware architecture of three-to-two and two-by-two is one-redundancy, when a single arithmetic unit/machine fails, the equipment loses redundancy but can normally operate, and when two arithmetic units/machines fail, the function of the whole equipment is completely lost. Because the administrator module manages one or more control areas in a centralized manner, the administrator module has a large influence on operation when the function of the administrator module is lost, the redundancy capability of the administrator module needs to be further improved, and the reliability of the administrator module is further improved.
Optionally, each control area is provided with a main manager module and a standby manager module, the standby manager module becomes the main manager module when the main manager module fails or quits operation, and a train is selected from an available manager module resource pool as the standby manager module; when the standby administrator module fails or quits operation, selecting a train from the available administrator module resource pool as the standby administrator module;
optionally, a second standby administrator module is added to each control zone when there is a higher demand for the reliability of the administrator modules. When the main manager module fails or quits operation, the first standby manager module becomes the main manager module, the second standby manager becomes the first standby manager, and a train is selected from the available manager module resource pool as the second standby manager module; when the first standby administrator module fails or quits operation, the second standby administrator module becomes the first standby administrator module, and a train is selected from the available administrator module resource pool to serve as the second standby administrator module; when the second standby administrator module fails or quits operation, selecting a train from the available administrator module resource pool as the second standby administrator module;
the system comprises a main administrator, a first standby administrator module and a second standby administrator module of a control area, wherein the main administrator, the first standby administrator module and the second standby administrator module of the control area are required to be three different administrator modules, namely one administrator module only can play the role of one administrator module in the main administrator module, the first standby administrator module and the second standby administrator module of the control area;
the available manager module resource pool is used for counting and storing the available manager modules according to the real-time working conditions of the manager modules and the real-time working conditions of the trains;
each train has the condition of becoming a vehicle-mounted administrator module, and non-administrator module trains which are put into operation or administrator module trains of which the number of administration control areas does not reach the maximum administration capacity are put into an available administrator resource pool; the failed train, the train that is about to exit the operation, or the administrator module train whose number of jurisdiction control areas has reached the maximum jurisdiction capacity is removed from the pool of available administrator resources.
Selecting an administrator module from the pool of available administrator module resources according to a certain priority; for example, a first priority may be to select a non-supervisor train with an overlapping route/plan with a control area, a second priority may be to select a non-supervisor train with an overlapping route/plan with a control area, and a third priority may be to select a supervisor train with the highest remaining jurisdiction capacity.
In addition, the remaining online time (the time difference between the operation exit time and the current time) of the train in the available administrator module resource pool, the communication condition between the train and the OC equipment in the control area and the like can be considered when the priority of the administrator module is determined;
and the control module sets the number of the administrator modules for each control area, and selects the administrator modules from the available administrator module resource pool for supplementation when one control area lacks the administrator modules.
When the administrator module device is used for managing fixed control areas, each control area only has one fixed administrator module, an administrator module A machine fails, the administrator module device loses redundancy but can normally operate, when an administrator module B machine also fails, the function of the administrator module in a control area is completely lost, and the whole control area needs degraded operation; when the administrator module equipment dynamically selects (according to the scheme provided by the patent), each control area has three administrator modules, namely a primary administrator module, a first standby administrator module and a second standby administrator module, each administrator module adopts a hardware architecture of two-by-two or two-by-two, when the A machine of the primary administrator module fails, the primary administrator module equipment can normally operate (lose redundancy), when the B machine of the primary administrator module also fails, the standby administrator module becomes the primary administrator module, and a method for switching the standby administrator module into the primary administrator module can be selected.
Further, the principle of the present invention is explained in conjunction with fig. 2-5;
referring to fig. 2, the known route is divided into 5 control areas, namely a vehicle section control area, a positive line control area 1 to a positive line control area 4.

16 T15 is put into operation, the administrator of the vehicle section and the positive line control area 1 to the control area 4 does not change, and T15 is put into the available administrator module resource pool.
Case two: and after the operation is finished, the trains which are put into operation are gradually reduced until 15 trains are all quitted from operation.
