Embodiment Construction
[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] Such as figure 1 As shown, in the railway track monitoring sensor network, the railway track monitoring sensor network controller is the core control device of the entire railway track monitoring sensor network, responsible for all the railway track monitoring sensor access multiplexing equipment in the network control management. The railway track monitoring sensor network controller 1 and the railway track monitoring sensor network controller 2 are mutually active and standby control devices, and jointly manage the railway track monitoring sensor network. The railway track monitoring sensor network controller 1 is the main control device. When the railway track monitoring sensor network controller 1 fails, all the railway track monitoring sensor access multiplexing devices will start to control the railway track monitoring senso...
