L-DNA simulate monitoring method and system of long city tunnel

Abstract

The invention discloses an L-DNA simulate monitoring method of a long city tunnel, comprising the following steps of: judging the states of monitoring nodes according to the master-slave station marks of the monitoring nodes; when the states are the master station mode states, carrying out network polling to acquire the global information of the whole tunnel; executing the global control logic ofthe whole tunnel according to the global information, issuing a global control command to a network, executing local control logic; when the states are the slave station mode states, carrying out network monitoring to acquire the global information of the whole tunnel; executing the global control logic of the whole tunnel according to the global information; and executing the local control logicaccording to the global control command. In the method, each monitoring node has the global control logic and the global data field of the whole tunnel, just like an organism cell, each individual contains the whole DNA genetic information, and therefore, each monitoring node can become a master control node, thereby realizing the tunnel monitoring under the conditions of traffic operation or tunnel damage and the like and ensuring the personal security. The invention intercommunicates with controllers within the boundary range to carry out privileged class coefficient agreement arbitration, and therefrom, a controller exerting the function of a master controller is provided by the arbitration. Meanwhile, the invention discloses an L-DNA simulate monitoring system of the long city tunnel.

Description

technical field [0001] The invention relates to the field of control engineering, in particular to an L-DNA (DNA-like) bionic monitoring method suitable for urban long tunnels and ultra-long tunnels. Background technique [0002] Nowadays, the control structure of long tunnel and ultra-long tunnel monitoring system is that each monitoring point is randomly hashed in the narrow and long linear area according to the needs of on-site control. Therefore, long tunnel and ultra-long tunnel monitoring system usually adopts distributed or distributed Segment centralized control topology. This monitoring structure is often designed with one or several main controllers and several distributed regional controllers, which communicate through a fieldbus network. The main controller contains global control logic and global information parameters, and the regional controller contains local control logic and remote execution and acquisition programs. When the system is working, the main c...

AI Technical Summary

Problems solved by technology

The situation that often occurs is that the tunnel has been opened to traffic and the monitoring system is still being installed and debugged, which seriously affects the construction safety and construction quality

[0004] In addition, the characteristics of tunnel disasters determine that once a disaster occurs at a certain point in the tunnel, all equipment and networks near the node may be destroyed, because the tunnel monitoring system relies heavily on the working conditions of the main controller and the integrity of the communication network , once the main controller fails, the tunnel will be paralyzed as a whole; even if it is only a network failure, all equipment behind the failure point will fail, leading to aggravated disasters and even secondary damage
