Problems solved by technology

[0005] There are great disadvantages in direct linkage by FAS professional. First of all, only the fire signals at the platform and station hall can receive the alarm source with FAS equipment, while the train fire in the tunnel section can only be through manual communication or temperature sensing. The optical fiber sends temperature alarms to the temperature-sensing optical fiber host. According to the current professional integration and interconnection division, the temperature-sensing optical fiber professional and the comprehensive monitoring professional (or other systems with similar linkage functions, such as equipment and environmental monitoring systems) are interconnected. It will not directly transmit the fire alarm signal to the FAS host or BAS equipment, resulting in that the BAS-related fans cannot be directly linked
Secondly, it is directly connected to the BAS through the FAS, lacks a redundancy mechanism, and lacks a backup plan if the linkage fails
Finally, for the center and station-level control personnel (environmental adjustment), this method is a passive party to receive information and has no authority to operate directly. Although this reduces the error rate that may be caused by manual operation, it lacks manual supervision and The necessity of global control in the control center
[0006] Setting up the main control system separately for linkage also has the following disadvantages. First, the command path is too long. The fire alarm information can only be linked to related equipment after passing through multiple systems such as the train alarm system, the central main control system, and the station main control system. If any link fails, the entire linkage process will fail, and its reliability and redundancy mechanism need to be strictly tested
Secondly, the cost is too high: setting up the main control system separately requires at least the configuration of active and standby servers and workstations in the center, as well as station-level servers and workstations in each station, which is not cost-effective

Embodiment Construction

[0042] In the following, the present invention will be described in detail from two aspects of fire linkage strategy and system linkage software design in combination with specific implementation methods.

[0043] Interval fires mainly refer to the occurrence of fires in trains during interval operation. When a fire occurs, there are two types of signal sources: manual alarm and automatic alarm. When a fire breaks out during the operation of the train, the driver obtains fire information through the train fire alarm or passenger alarm, and reports to the OCC through the communication system (telephone); When a fire breaks out while the train is running in the section, the temperature-sensing optical fiber detection point in the tunnel sends the high-temperature telemetry signal to the temperature-sensing optical fiber host, which judges whether it is a fire signal through the temperature-sensing optical fiber host and sends it to the station BAS server through the interface pro...

Abstract

The invention discloses a fire linkage control method and system, wherein the method and the system are applied to urban rail transit. The system uses environment equipment and a monitoring system as a platform to carry out interface relevance with various specialties. According to actual situations, a comprehensive linkage scheme is developed and is operated by a user. The coordination linkage ability of fire disaster relief can be greatly improved. The efficiency of disaster relief is improved. According to the invention, through a redundancy mechanism, the reliability and the stability of a fire disaster relief system are enhanced; when an overall system scheme is designed, an optimized fire alarm confirmation technology is used; the method of combined and mutually redundant FAS and BAS is used for linkage; a unique fire mode instruction transmission and receiving technology, an advanced fire mode instruction decomposition technology and a fire mode linkage control drive technology are used; processing programs carry out communication for various kinds of different professional equipment; and various kinds of data are processed to develop the complete linkage scheme for the user to choose.

Description

technical field [0001] The invention belongs to the field of urban rail transit systems, and in particular relates to a rail transit fire linkage method based on environmental equipment and a monitoring system applied in a disaster mode of the urban rail transit system. Background technique [0002] Most of the urban rail transit system is located in the closed section composed of underground stations and tunnels. Isolated from the natural environment on the ground, people and equipment are highly dense. Once a fire breaks out, the fire spreads rapidly, and the accumulation of dense smoke is difficult to discharge, making it extremely difficult to evacuate people and fight the fire. Therefore, all kinds of fire linkages for subway fires are extremely critical. At present, the rail transit in most cities in China has the following two fire-fighting linkage handling methods for fires: [0003] (1) Smoke detectors, temperature sensors, manual alarm devices, etc. arranged in ...
