Embodiment 1
[0029] refer to figure 1 , a kind of user machine that the present invention proposes automatically recognizes the method for master-standby switchover of commander machine, by arranging main commander machine and backup commander machine, so that when the master commander machine fails, user machine can switch to communicate with backup commander machine, to ensure The stability of data transmission.
[0030] The method for the user machine to automatically identify the active / standby switching of the command machine specifically includes the following steps:
[0031] S1. Set up one main command plane and one or more backup command planes, and respectively set signal channels for the main commander plane and the backup command planes to communicate with the user machines.
[0032] In this step, setting up a backup commander plane can basically meet the needs of the main commander plane failure, but in order to avoid the unexpected situation that the backup commander plane an...
Embodiment 2
[0045] refer to figure 2 , a kind of user machine that the present invention proposes automatically recognizes the method for master-standby switchover of commander machine, by arranging main commander machine and backup commander machine, so that when the master commander machine fails, user machine can switch to communicate with backup commander machine, to ensure The stability of data transmission.
[0046] The method for the user machine to automatically identify the active / standby switching of the command machine specifically includes the following steps:
[0047] S1. Set up a main command plane and multiple backup command planes, and respectively set signal channels for communication between the main commander plane and the backup command planes and the user machines, and configure switching sequences for each backup command plane.
[0048] In this step, setting a backup command plane can basically meet the needs of the main commander when the failure occurs, but in or...

Abstract
The invention discloses a method for a user machine for automatically identifying switch between an active director and a standby director. The method for the user machine for automatically identifying the switch between the active director and standby director includes steps that S1, setting one active director and one or more standby directors, and respectively setting signal channels for enabling the active director and standby director to communicate with the user machine; S2, enabling a data gathering terminal to preset a communication address of the active director; S3, enabling the data gathering terminal to communicate with the active director through the user machine; S4, judging whether the active director is normal; S5, if the active director is normal, returning to the step S3; S6, if the active director is abnormal, switching to the standby director to communicate with the user machine; S7, enabling the standby director to send a parameter correction command to the data gathering terminal; S8, enabling the data gathering terminal to correct the stored address of the active director into the address of the standby director; S9, enabling the data gathering terminal to communicate with the standby director through the user machine. The method for the user machine for automatically identifying the switch between the active director and standby director solves the problem that a single Beidou director is incapable of avoiding communication outage.
Description
technical field [0001] The invention relates to the technical field of Beidou communication, in particular to a method for a user machine to automatically identify and switch between master and standby of a command machine. Background technique [0002] At present, many small hydropower plants, small thermal power plants, photovoltaic power plants and other non-communicated power plants do not have conventional communication methods such as networks and dedicated lines due to geographical location. However, if these non-regulated power plants are connected to wireless transmission signals, dedicated lines are often laid The cost is high and the construction is difficult. [0003] In view of the above situation, at present, the communication method of Beidou channel is mostly used to solve the communication problems of non-unified dispatching power plants. Specifically, data acquisition terminals and Beidou user machines are installed in non-unified dispatching power plants, ...
