Description

Method for judging main operating machine of computer interlocking system
Technical Field
The application relates to the technical field of computer control, in particular to a method for judging a main operating machine of a computer interlocking system.

When the system is used, in order to realize functions of master-slave channel management of interfaces of external systems such as a dispatching set and the like, priority management of operation instructions between operation machines and the like, a plurality of operation machine devices need to be distinguished from master-slave attributes through a certain algorithm. According to the requirements of the China's republic of China railway industry standard TB/T3496-. Interfacing with other external systems (including but not limited to train dispatch command systems, marshalling yard combination automation systems, wireless shunting cab signal and monitoring systems, automatic train monitoring systems, subway car base integrated automation systems, cell console systems, etc.) also requires only one main operator to be present among the interfacing operators.
The existing main operating machine judging algorithm is that all operating machines establish communication in pairs, then according to a preset operating machine equipment list sequence, the first operating machine is preferentially used as a main operating machine, when the communication between the operating machine and other operating machines is interrupted, the operating machine is determined to be in fault, and then the second list of operating machine equipment is used for applying to be used as the main operating machine. Patent CN112433979A discloses a switching method of multiple operation machines: and a switching device is used outside the operating machine to acquire the operating states of the operating machine and the adjacent operating machines, and make a decision and control the switching of the main operating machine.
The defects are as follows:
1. relying heavily on communication between the operating machines. When the network communication between the operation machines is intermittent, the main operation machine may jump continuously, and the phenomenon of multiple main operation machines is also easy to occur.
2. Other hardware switching devices may be relied on, the use cost is high, and the maintenance is troublesome. The number of operating machines connected with the device at the same time is limited, and the device is difficult to support a large station.
3. When the first list operator and the second list operator fail at the same time. The third list operator is difficult to judge that the third list operator should be regarded as the main operator at present.
4. Only one main operator can be present at the same time. Therefore, the computer interlocking system cannot be simultaneously interfaced with two dispatching centralized protocol systems.

Detailed Description
The following describes a method for determining a main operating machine of a computer interlocking system in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, the method for determining a master operating machine of a computer interlocking system in a certain station provided by the present invention includes 7 operating machines, wherein an operating machine a, an operating machine B, an operating machine C, an operating machine D, and an operating machine E are disposed in a first room and are a first operating machine group, and the operating machine a and the operating machine B are class I operating machines and are respectively connected to a dispatch centralized system and an interlocking lower computer through interface communication; the operation C machine and the operation D machine are II-type operation machines and are only in communication connection with the interlocking lower computer through an interface; the operation E machine is a class III operation machine and is not in communication connection with the dispatching centralized system and the interlocking lower computer through interfaces; the operation F machine and the operation G machine are arranged in a second room and are second operation units, and the operation F machine and the operation G machine are I-type operation machines which are respectively in communication connection with the wireless shunting locomotive signal and monitoring system and the interlocking lower computer through interfaces. The first operating unit and the second operating unit jointly form a computer interlocking system.
When all the equipment of the station normally run, only one main operating machine exists in the first operating machine set in the computer interlocking system at the same time, the lower computer preferably selects a class I operating machine (i.e. an operating machine A or an operating machine B) as the main operating machine, and selects a class II operating machine (i.e. an operating machine C or an operating machine D) as the main operating machine. In the second operation unit, only one main operation machine exists at the same time, and is one of the operation F machine and the operation G machine.
Firstly grouping operation machines into operation machine groups according to an interface mode and an equipment user role in a computer interlocking system; in actual use, users have different roles or authorities (whether or not a certain function can be executed) depending on the work location (such as the first room and the second room), and as shown in fig. 1, the roles of the users operating the a machine, the E machine, and the F machine are different, and the users are taken as the basis for grouping the operating machines. Wherein each operating machine is affiliated to a unique operating machine set; independently selecting a main operating machine in each operating machine group in the computer interlocking system; therefore, the computer interlocking system can support a plurality of sets of external systems to be simultaneously connected with the operating machine of one set of computer interlocking system through an interface.
In this embodiment, the manner of selecting the main operating machine in the same operating machine group includes the following contents:
s1: the operation machines are divided into three types in the same operation machine set: the interlocking system comprises a class I operating machine, a class II operating machine, a class III operating machine and a control system, wherein the class I operating machine is connected with an external system and an interlocking lower computer through interfaces;
the I-type operating machine and the II-type operating machine can be in communication connection with the interlocking lower computer through double networks (a first network A and a second network B);
wherein the external system comprises: the system comprises a dispatching centralized system, a train dispatching command system, a marshalling station combined automation system, a wireless shunting locomotive signal and monitoring system, an automatic train monitoring system, a subway vehicle base comprehensive automation system and a unit console system.
S2: respectively assigning three different initial health values X, Y, Z to the three types of manipulators, wherein X > Y > Z, X represents the health value of the type I manipulator, Y represents the health value of the type II manipulator, and Z represents the health value of the type III manipulator; in the present embodiment, the initial health value is set to X equal to 100, Y equal to 80, and Z equal to 0.
S3: in each communication cycle, performing point adding updating or point subtracting updating on each health value according to the type of each operating machine and the change of the communication state between each operating machine and the interlocking lower computer and the external system; wherein the added value or the subtracted value is a preset value.
S4: in each communication period, selecting the operating machine with the maximum health value in the same operating machine group in the computer interlocking system as a main operating machine of the operating machine group; and if the health values are equal in the same operation unit, selecting the operation machine which establishes communication connection with the interlocking lower computer earlier as the main operation machine of the operation unit.
In the above initial assignment method of the health value and the update method of the health value adding, subtracting, etc., it is required to satisfy that the maximum value that the health value of the class II manipulator may reach is smaller than the minimum value that the health value of the class I manipulator may reach, that is, to ensure that the class I manipulator is preferentially selected as the main manipulator under the condition that the class I manipulator works normally. Specifically, in a first communication cycle after each operating machine of each operating machine group in the computer interlocking system is started, the updating mode of each health value is as follows:
after the class I operating machine is started, the class I operating machine and the interlock lower computer are changed from an un-communication state to a communication normal state (the class I operating machine and the interlock lower computer are both considered to be in a normal communication state through dual-network connection communication, or through first network a single-network connection communication, or through second network B single-network connection communication, and when the class I operating machine and the interlock lower computer are in a non-communication state or a communication failure, the communication is considered to be in a normal state), the health value X of the class I operating machine and the interlock lower computer is increased by a first preset value a, wherein a is 10 in the embodiment; when the class I operating machine and the external system are changed from the non-communication state to the communication state, the health value X is increased by a second preset value b, where the first preset value a is greater than the second preset value b, and b is 5 in this embodiment. That is, in this embodiment, if the class I operating machine, the interlock lower computer, and the external system are all converted from the non-communication state to the communication state, the health value X is adjusted from the initial 100 to 115; when the class I operating machine and the interlocking lower computer are only changed from an un-communication state to a normal communication state, the health value X of the class I operating machine is adjusted from the initial 100 to 110; when the class I manipulator and an external system only change from a non-communication state to a normal communication state, the health value X of the class I manipulator is adjusted from an initial value of 100 to 105; otherwise, the health value X of the class I operating machine is not changed and is kept at 100.
After a class II manipulator is started, when the class II manipulator and an interlocking lower computer are changed from an un-communication state to a normal single-network communication state through a first network A or a second network B, a health value Y of the class II manipulator and the interlocking lower computer is increased by a third preset value c, wherein the third preset value c is half of the first preset value a and meets the relation that X is more than Y +2c, and c is 5 in the embodiment; when the class II operating machine and the interlocking lower computer are changed from an un-communication state to a normal state through dual-network communication, the health value Y of the class II operating machine and the interlocking lower computer is increased by 2 times of a third preset value c, namely 10; when the communication between the class II operating machine and the interlocking lower computer is abnormal (the dual-network is not communicated or the dual-network communication fails), the health value Y is not changed. That is, in this embodiment, if the class II operating machine and the interlock lower computer are changed from the non-communication state to the normal state through the dual network communication, the health value Y is adjusted from the initial 80 to 90; if the class II operating machine and the interlocking lower computer are changed from an un-communication state to a normal state through single-network communication only through the first network A, the health value Y of the class II operating machine and the interlocking lower computer is adjusted to 85 from the initial 80; if the class II operating machine and the interlocking lower computer are changed from the non-communication state to the normal single-network communication through the second network B, the health value Y is adjusted to 85 from the initial 80; otherwise, the health value Y of the class II operating machine is not changed and is kept at 80.
After the III-class operating machine is started, the health value Z is always an initial value 0, namely the health value Z is not updated all the time; the class III manipulator is always used as a standby machine.
Further, in step S2, an initial health value X + δ is given to one of the I-class manipulators, δ being greater than the second preset value b; on the premise that the operating machine and the interlocking lower computer are normally communicated, the operating machine is always appointed as a main operating machine in each communication period.
In this embodiment, as shown in fig. 1, the dispatch centralized interface protocol requires that two class I operating machines (an operating machine a and an operating machine B) connected to the dispatch centralized system are cross-interconnected with two autonomous machines, and if it is required to designate an operating machine a of the two class I operating machines as a main operating machine preferentially, a higher initial health value X + δ may be given to the operating machine a of the designated class I operating machine in step S2, where δ is greater than 5; in this embodiment, the initial health value given to the operation a machine may be 106, that is, δ is 6; and giving the initial health value of 100 to the operation B machine in the class I operation machine. In this case, when the operation a machine communicates normally only with the interlocked lower computers, its health value X + δ is increased by 10 to adjust to 116. Even if the operation B machine communicates with the interlocking lower computer and the dispatching centralized system normally at the same time, the health value X of the operation B machine is adjusted to be 115 and is still smaller than the health value of the operation A machine 116, so that the operation A machine automatically becomes a main operation machine of the operation unit. At this time, when the autonomous machine detects that the operation A machine is the main operating machine, the autonomous machine automatically switches and determines that the interface channel of the operation A machine is the main operating machine channel, so that the health value of the operation A machine is adjusted to 121, and the health value of the operation B machine is adjusted to 110.
Still further, in step S2, the initial health values Y of different sizes are given to n of the class II manipulators 1 、Y 2 、……、Y n (ii) a Wherein Y is 1 >Y 2 >……>Y n And X>Y 1 + a. The scheme can specify the priority of each operating machine in the II type operating machines, and is used for judging scenes of the main operating machines under the condition that the operating machines have differences of hardware, function authority, environment and the like.
In this embodiment, the class II manipulator in the first manipulator group includes: operating the machine C and the machine D; the initial health value of the operation C machine is set to be 85, and the initial health value of the operation D machine is set to be 80. When the operation C machine and the interlocking lower computer are communicated normally through the dual network, the health value is adjusted to 95 and is smaller than the minimum value 100 of the health value of the class I operation machine, under the condition that the class I operation machine works normally, the class I operation machine is preferentially selected as the main operation machine, the operation C machine of the class II operation machine is selected as the main operation machine, and the operation D machine of the class II operation machine is selected as the main operation machine again.
According to the above, in each communication cycle after the startup of each operating machine group in the computer interlocking system, the specific steps for updating the health value of each operating machine are as follows: judging the type of the manipulator when the manipulator is started, and if the manipulator is a type I manipulator, entering S31-S34;
s31: reading the current health value of the class I operating machine (if the current communication cycle is the first communication cycle after the class I operating machine is started, the read current health value is the initial health value);
s32: judging the communication state of the class I operating machine and the interlocking lower computer, and if the communication state is changed from communication failure or non-communication to normal communication, increasing the health value by 10; if the communication state is changed from normal communication to communication fault or no communication, subtracting 10 from the health value; if the communication state is not changed, the health value is not changed;
s33: judging the communication state of the class I operating machine and an external system, and if the communication state is changed from communication failure or non-communication to normal communication, increasing the health value by 5; if the communication state is changed from normal communication to communication fault or not, subtracting 5 from the health value; if the communication state is not changed, the health value is not changed;
s34: the I-type operating machine sends the health value updated in real time to the interlocking lower computer, and if the I-type operating machine and the interlocking lower computer are normally communicated, the interlocking lower computer receives the health value updated in the communication period; if the communication between the class I operating machine and the interlocking lower computer is abnormal, the interlocking lower computer cannot receive the health value updated in the current communication period.
Specifically, the type of the manipulator is determined when the manipulator is started, and if the manipulator is a type II manipulator, the process proceeds to steps S35 to S38;
s35: reading the current health value of the class II operating machine (if the current communication period is the first communication period after the class II operating machine is started, the read value is the initial health value);
s36: judging the communication state of the first network A between the class II operating machine and the interlocking lower computer, and if the communication state is changed from communication failure or non-communication to normal communication, increasing the health value by 5; if the communication state is changed from normal communication to communication fault or not, subtracting 5 from the health value; if the communication state is not changed, the health value is not changed;
s37: judging the communication state of a second network B between the class II operating machine and the interlocking lower computer, and if the communication state is changed from communication failure or non-communication to normal communication, increasing the health value by 5; if the communication state is changed from normal communication to communication fault or not, subtracting 5 from the health value; if the communication state is not changed, the health value is not changed;
s38: the class II operating machine sends the health value updated in real time to the interlocking lower computer, and if the class II operating machine and the interlocking lower computer are normally communicated, the interlocking lower computer receives the health value updated in the communication period; if the class II operating machine is not communicated with the interlocking lower computer normally, the interlocking lower computer cannot receive the health value updated in the current communication period.
Specifically, the type of the manipulator is determined when the manipulator is started, and if the manipulator is a class III manipulator, the step S39 is performed;
s39: the health value of the class III operating machine is not updated all the time, and the class III operating machine is used as a standby machine all the time.
And repeatedly executing the steps until the health values of all the operating machines in the computer interlocking system are updated in the communication period.
In each communication cycle after each operating machine of each operating unit in the computer interlocking system is started, the specific steps for judging the main operating machine are as follows:
s41, in the communication period, the interlocking lower computer receives all updated health values sent by the operating machines which are in normal communication with the interlocking lower computer;
