Embodiment Construction
[0019] see figure 1 . The railway monitoring data transceiver includes a control unit and a local area network wireless communication unit connected to it, a wide area network wireless communication unit, a data storage unit, a timing sending judging unit and an instruction sending judging unit.
[0020] see figure 2 , the method for sending and receiving railway monitoring data of the present invention comprises the following steps:
[0021] a. Determine whether the following two conditions are true:
[0022] a1) Whether the current time is in line with the preset sending frequency, a2) Whether an alarm command from the LAN is received,
[0023] If both are true or either of them is true, go to step b, if neither of them is true, go to step c;
[0024] b. Receive the signal data from the local area network, send the signal data to the remote server via the wide area network after packaging; if the transmission is successful, enter step c, and if it fails, store the signa...
