Description

A method for generating optical nameplates for rail transit comprehensive monitoring system

technical field

The invention relates to a method for generating an optical plate of a rail transit integrated monitoring system (Intergrate Supervision and Control System, referred to as ISCS), which belongs to the urban rail transit technology.

Background technique

With the rapid development of domestic urban rail transit and automation technology, more and more subway lines have begun to consider or are already implementing integrated monitoring systems. There are a large number of alarm points in the rail transit integrated monitoring system, which can reach 200,000 to 300,000 according to statistics, and there are many levels of alarms, and the on-duty staff often only care about important alarm points with high levels.

At present, the system lacks effective means of information layering and filtering, and cannot clearly display the actual operation, abnormalities and accidents of the equipment through the alarm window of the system. When a fault occurs, it can be displayed in a hierarchical manner, so that the on-duty personnel can quickly lock the location of the alarm point (the equipment and equipment group it belongs to), so as to facilitate the on-site personnel to troubleshoot.

In the previous integrated monitoring system, the optical nameplate was realized by associating data sources with graphic elements. If a certain equipment or equipment group has n protection signals, it needs n graphic elements to be associated with n data sources. When the number of optical plates used for key equipment in monitoring is large, the production of graphic files will be very cumbersome. Therefore, the traditional method is low in production efficiency, inflexible in configuration, and difficult to maintain in the later stage.

Fig. 1 is the workflow diagram of optical plate in the present invention.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, it is a work flow chart of the light plate of a kind of rail transit comprehensive monitoring system, and its realization method comprises the steps:

(1) Establish the equipment group information table, equipment information table and equipment protection signal information table in the database according to the requirements of the rail transit integrated monitoring system, and the information tables are related by keywords;

(2) Configure the number and size of the optical name plate module, and set the data source, alarm priority and display style of each optical name plate module, and make the optical name plate image file by loading the optical name plate module;

(3) The optical plate module configures the data source information according to the change data and periodic full data provided by the service program, and changes the display style according to the data source information to display the current actual status and alarm status of the equipment and/or equipment protection signals.

The data in the equipment group information table, equipment information table and equipment protection signal information table are first downloaded to the real-time database, and all periodic data and data source information are stored in the real-time database.

The service program mainly deals with two attributes of the optical name plate, which are the summary value (that is, the priority of the alarm) and the summary status (that is, whether to alarm or not). Specifically, the service program interacts with other modules in the integrated monitoring system to Read the summary value and summary state of the equipment protection signal information table, synthesize the summary value and summary state of the equipment information table and the equipment group information table, and send the message to the optical plate module; the optical plate module according to the report provided by the service program Text and periodic full data configuration data source information, and change the color and/or flashing state of the corresponding optical plate according to the data source information, and display the current actual state and alarm state of the equipment and/or equipment protection signals.

Since the equipment protection signal has an alarm priority, but there is no alarm priority for equipment and equipment groups, but the optical name plate needs to also display the alarm priority of the equipment or equipment group, so the summary value and summary of the equipment information table and equipment group information table The state should contain the content of the alarm priority, and the summary value and summary status of the equipment information table and equipment group information table can be obtained through the synthesis method. Specifically: the summary status value of the equipment protection signal information table is under the device The binary value of the protection signal of the alarm equipment that appears, the summary value of the equipment protection signal information table is the binary value of the alarm priority of the equipment protection signal that appears under the equipment; the summary status value of the equipment information table is the The binary composite value of all alarm equipment protection signals that appear, the summary value of the equipment information table is the binary value of the alarm priority of all alarm equipment protection signals under the equipment; the summary status value summary value of the equipment group information table is this The binary composite value of all alarm devices under the group device, and the summary value of the device group information table is the binary value of the alarm priority of all alarm devices under the group device.

For example, if a certain equipment has equipment protection signal alarms with alarm priority levels 1 and 2, the binary "11" will be synthesized, and the synthesized value will be shifted to the right by n bits, and then it will be ANDed with 1 to calculate whether the equipment has n-level protection signals. Alarm, if there is no alarm for all equipment protection signals under the equipment, the summary value of the equipment information table is 0; the calculation method of the summary status value of the equipment information table is similar. The calculation method of the summary value and the summary status value of the device group information table is also similar.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also possible. It should be regarded as the protection scope of the present invention.
