Background

At present, urban rail transit construction in China is accelerated, and many cities enter an online operation stage. Originally, the early lines were provided with exclusive main substations, and now more and more shared main substations appeared, while providing power supply for two or more lines. However, the construction mode of the electric SCADA system is still attached to a certain subway line, and the control right of the main substation and the main line substation belongs to one line, so that global control cannot be realized in the subway line network center, and emergency response and power supply optimization cannot be performed. Specific problems include:

first, the control technology is limited to a line control system, and the emergency response capability is limited

The program control card is only limited to be used by a line control system, when the network center coordinates, the instruction can be issued only through a dispatching telephone, and then the line executes the program control card, and the emergency response capability is limited when an emergency occurs.

Secondly, after the line is extended or a new line is accessed, the power supply logic of the line network is changed greatly and the operation of the existing system is influenced

The power supply range of the shared main substation is subjected to power supply logic change along with the extension of a line and the access of a new line, at the moment, the original control program needs to be modified and expanded, and the code modification amount is large. And repeated debugging is needed, which has a great influence on the running line.

Third, access difficulties to different lines

The existing program control technology has the defects, so that it is necessary to develop a new technology for the rapid power failure operation and the power transmission operation of the urban rail transit network center.

Patent CN103513962A discloses a method for parallel control of electric SCADA based on a small computer, which has limitations on both the computer type and the operating system, and adopts a program control card to perform parallel control only on a single line through a preset execution sequence. This patent fails to address the issue of common instructions between systems of different vendors on different lines in a net.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.

Example 1

The implementation 1 provides a distributed parallel control method for subway network electric power SCADA. The method provides solutions to the following three problems.

One) solving the problem that control power is limited by the line

The line opens the safety command authority to the line network, and the line network generates a line control instruction sequence according to the command instruction to control the related power equipment of the line. And the lines can execute instructions in parallel, thereby greatly improving the emergency response capability.

Second) solve the problem of system capacity expansion after line extension or new line access

After the line is extended or a new line is accessed, the modification of a program and the seamless expansion of a system are avoided. The control part adopts a general control code, and the remote control point configuration, the locking logic configuration, the information configuration and the like are stored by adopting a relational database.

Thirdly) solving the problems of cross-platform compatibility and different manufacturer access

In order to adapt to the access problems of different monitoring platforms and different manufacturers, a universal component needs to be developed for the interface access between a line and a line network.

The embodiment is based on a universal power SCADA system monitoring platform, as shown in FIG. 2. The system is divided into three layers of structures, namely interface middleware, background service and human-computer interaction. The function and the implementation mode of each component are as follows:

one, interface middleware

The core of the interface middleware is the analysis, decomposition, translation and communication of the control instructions of the network.

The interface middleware is divided into a remote control middleware and a node middleware. The remote control middleware is responsible for analyzing which lines are involved in the control instructions of the line network, and which operations should be executed by the lines respectively; the node middleware is responsible for accessing the line system and translates the control instruction related to the line into a control command sequence of the line. As shown in fig. 1, taking an example that the net control command relates to 2 lines, the specific operation method is as follows:

1. the remote control middleware is the core of the whole remote control process, and analyzes and decomposes the operation steps of the line level of different power supply modes according to the logic structure of a line network power system, and then sends a universal control instruction to the related lines in a multi-thread parallel mode.

2. The node middleware comprises instruction translation and communication driving processes, and comprises communication protocols commonly used by an electric SCADA system. The instruction translation translates the general control instruction of the line network into a control instruction sequence specific to the line system; and the driver is responsible for accessing and communicating the SCADA system of the line.

The remote control middleware is specifically designed as follows

After the wire network control data is read, the execution steps are as follows:

(A1) the background service sends out an execution demand, the system establishes a main thread for controlling execution, the thread analyzes the general control logic of the execution demand, the related lines and the control logic of each line according to the data of the network power supply logic, the line power supply logic and the like in the database, establishes the line control sub-threads with the same number for the lines related to the operation, and simultaneously establishes a timer sub-thread and a message queue.

The timer is responsible for the synchronization and timing of each control sub-thread, and the message queue is responsible for the communication between the sub-threads

(A2) Controlling the main thread to create a shared memory area, and distributing three state fields and one instruction field for each line control sub-thread:

a. the operation state field is respectively operation, suspension, completion and closing;

b. run step field, i.e. execute to the step of the control sequence;

c. a wait state field including the wait time and wait state of the child thread;

d. an instruction field for notifying the sub-thread by the controlling execution main thread.

Each line control sub-thread can read the state fields of other sub-threads, but only can maintain the state fields distributed by the sub-thread; the executing primary thread may read the status fields of all the secondary threads. The instruction field is maintained by the executing main thread as a precondition for the execution step of each sub-thread.

(A3) Each line control sub-thread is independently communicated with the line power SCADA system, control instructions decomposed to the line are translated into a control sequence specific to the line, then a power remote control process of the sequence is executed according to the step sequence, and the state field of the line is correspondingly maintained.

(A4) The actual power remoting process is performed by the line power SCADA system and feeds back the execution status of each step to the net. The timer sub-thread informs each line control sub-thread at regular time, each sub-thread maintains a self waiting state field, if the sub-thread is in a waiting state and the waiting time exceeds a preset value, the sub-thread immediately feeds back to the execution main thread, and the execution main thread judges how to perform overtime processing, including abandoning the whole operation, abandoning the line operation, submitting manual processing and the like.

(A5) Generally, each line control sub-thread is run independently, but if the state field value of another line control sub-thread is required as a precondition for a certain step thereof. The child thread puts the current condition requirement into a message queue to wait for feedback, and the child thread waits to be suspended. And when the precondition in the message queue is fed back successfully, the message queue is removed and used for awakening the suspended sub-thread.

(A6) And the timer sub-thread notifies the execution main thread at regular time, and the main thread traverses the state field of each line control sub-thread. When the main thread monitors that all the sub-threads finish running or are abandoned, the execution is finished. The flow ends.

The line control sub-thread fails in the following processing mode:

(B1) when a certain sub-thread goes wrong, namely, the operation failure of a certain step is reported, the sub-thread maintains the operation state field, suspends the execution flow and waits for the execution main thread to inform the processing mode.

(B2) When a certain sub-thread is executed to a certain step and the state field value of another sub-thread is needed as a precondition, if the sub-thread as the precondition is abandoned to be executed due to a fault, the sub-thread also abandons execution and exits from running.

3. The node middleware and the remote control middleware interact with each other in a network communication mode, generally speaking, the remote control middleware runs on a main server of a network electric power SCADA system, and the node middleware runs on an interface server of a network and a line.

Two, background services

Background service is a framework of the whole method, the background service is used for processing external events and interacting key components for a database, and the background service is operated on a main server of a network power SCADA system.

Background services consist of several parts:

1. the human-computer foreground information is used for processing human-computer interface operations, such as remote control execution, exception handling and the like.

2. And the human-machine foreground message feedback is used for feeding back a program execution real-time process, a final result and the like.

3. And (4) interacting databases, and calling information such as a network power supply logic, a line power supply logic and the like.

Three, man-machine interface

The human-computer interface is only responsible for human-computer interaction and sends messages to the background service, so the method does not depend on a line-specific electric power SCADA monitoring platform.

Fourth, database structure

To realize program control and to adapt the method to seamless capacity expansion of a system and to reduce the amount of modification of a program after the capacity expansion of the system. The design of net and line powered logic is therefore very important. In principle, the net supply logic should not be dependent on the particular line supply logic that is provided by the line's power supply system. After the line is extended or a new line is accessed, the requirement can be met only by maintaining the line network power supply logic and the line power supply logic in the database through maintenance software, and the repeated debugging and program modification work of a program is avoided.

The net supply logic (mode) includes:

1. line information of an access line network comprises the number, the trend, the number of stations and the like;

2. the main substation information of each line comprises the number, the geographical position, the rated power, the maximum power, the normal power supply range, the maximum power supply range and the like;

3. the network normally supplies power logic, namely the power supply range of each main substation when all the main substations normally operate;

4. the network fault emergency power supply logic is that after the main substations in any combination quit operation due to faults, the power supply ranges of other main substations should be adjusted, and the adjustment of the power supply ranges of the shared main substations is mainly related.

The line powered logic comprises:

1. a power wiring diagram of the circuit;

2. master substation equipment information for the line;

3. contact switch device information of the line;

4. when the power supply range of the main substation is adjusted, the operation sequence of the equipment comprises the power supply range adjustment of the line and the power supply range adjustment of the cross-line;

the method relates to the dependence of the line on the operation of other line equipment when the cross-line power supply range is adjusted.

By adopting the method of the embodiment, a rapid, automatic and parallel control method can be realized in the power monitoring system of the subway line network, and the method can be suitable for different power SCADA monitoring system platforms of each line (on the premise of adopting an international or national standard power system communication protocol, if the protocol is a non-standard protocol, the method can be customized and developed according to the method of the embodiment). The embodiment can also be seamlessly adapted to line extension and new line access, and only the content of the database needs to be modified after capacity expansion, without modifying a control program.

In the embodiment, the original network informs the line to adjust the power supply range through the dispatching telephone, and the network directly commands the relevant line to adjust the power supply range through the system, so that the emergency response capability is greatly improved, and the effect is obvious. The monitoring platform of the line power SCADA system does not need to be modified, and the risk of function upgrading is reduced. In addition, the system capacity expansion and access adaptability to different power equipment manufacturers and system integrators is strong, and upgrading can be completed in a short time. The system upgrading does not need to modify the control program, and the stability of the program is improved. The automation and intelligence level of the power monitoring system of the subway line network is further improved.

The core of this embodiment is that the system automatically resolves the control command and automatically issues the device control sequence by configuring the network power supply logic and the line power supply logic in the database.

As shown in fig. 3, a software deployment diagram is taken as an example of a network accessing 4 lines, background service and control middleware is deployed in a power center server, node middleware is deployed in an interface server of each line, a relational database is deployed in a database server, and a human-computer interface is deployed in an operation workstation for power operators. The maintenance terminal is mainly used by maintenance personnel and can modify the power supply logic of the network and the power supply logic of the circuit in the database.

The embodiment does not limit the machine type and the operating system, is the parallel control of the network, and has the core that the system is adapted to systems of multiple lines and different manufacturers to automatically convert the instructions; and analyzing the line network power supply logic, and automatically generating an execution sequence by combining the line power supply logic.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
