Problems solved by technology
However, in the south of my country, due to the high temperature of the computer room, two servers in the station went down at the same time. In this case, dual-machine redundancy cannot meet the requirements of remote disaster recovery.
Therefore, there are also multi-machine redundancy solutions provided by some manufacturers in the industry. However, due to the realization of key technologies, such multi-machine redundancy solutions must be added to the price if they want to achieve multi-machine redundancy under the premise of fault isolation. Expensive server hardware resources, the final owner cannot accept such a solution

The embodiment of the invention discloses a method and a device for monitoring a station by a multi-machine redundancy way. The method is applied to a rail transit monitoring system and comprises the following steps: a first data processing unit obtains the data information of N stations which take the first data processing unit as a standby data processing unit; and the first data processing unit determines that the first data processing unit is updated into a master data processing unit of a second station under a situation that the station data processing unit of a second station system is under a non-master state, and the second station is monitored according to the data information of the second station. The embodiment of the invention deploys the data information of a plurality of stations in one data processing unit to realize an effect of multi-machine redundancy on the basis of a situation that a great quantity of hardware input does not need to be added, and the integral reliability of the system is effectively improved.
Description
technical field [0001] The invention relates to the field of rail transit, in particular to a method and device for monitoring a station in a multi-machine redundant manner. Background technique [0002] The rail transit comprehensive monitoring system undertakes the major task of monitoring the urban rail transit control center and station power, environmental control, signal, fire alarm and other subsystem equipment. It is the basic guarantee for the normal operation of the subway and disaster relief command, involving personal and Equipment Security. Therefore, the protection mechanism of the integrated monitoring system is very important, and the reliability and safety requirements are extremely high. In order to improve the reliability of the system, for the core real-time database system of comprehensive monitoring, the mainstream in the industry adopts the dual-machine redundancy method. After the real-time database system running on a single server fails, the real-t...
