Device sub-service configuration

server _ cnt _: the number of the sub-service processes is 1 by default. When the number of the devices is too large, a plurality of sub-services are required to be started, and the sub-services can be automatically adjusted according to the running condition.

heart _ beat _ interval: the sub-service sends the time interval of the heartbeat to the central service. When the sub-services are deployed on different machines, the sub-services may be discovered through heartbeat requests sent by the sub-services.

upper _ interval _: and each equipment sub-service reads the corresponding equipment state and actively reports the time interval. The state of the device cannot be read 100% in real time, and only can be relatively real-time, namely, the state is read once at regular intervals.

timeout _ connect _ and timeout _ read _: and the device sub-service reads the http connection of the device state and the timeout time of the read data.

upload _ time _ ranges: each service reports the time period of the data at regular time, and the format of hh is mm-hh is mm; allowing a plurality of time periods; the time periods are allowed to overlap (data is reported within any time period). If the current time is not within any configured valid time period, the device sub-service suspends the reading of the device state data, and network resources are saved.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and any simple modifications or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the technical scope of the present invention are within the scope of the present invention.
