Problems solved by technology

This method polls the device according to the scheduled polling list. The master control node needs to continuously send polling commands to notify the corresponding client to respond. It takes a long time to complete a polling and the polling efficiency is low.

Embodiment 1

[0019] Such as figure 1 As shown, the master control node broadcasts the polled terminal device list (the polled terminal device list can also be stored in the terminal device in advance), and the polled terminal device list contains the response sequence and data protection interval of each terminal device Duration; the master control node broadcasts the polling start response command to all terminal devices; the terminal devices respond in turn according to the response order specified in the list of polled terminal devices. The specific implementation is: the first one set in the list of polled terminal devices The terminal device always responds immediately, and other terminal devices automatically start to answer after a period of time delay (that is, the data protection interval) after hearing that the previous terminal device has completed the data response, until the polled terminal device is at the end of the list. Polling ends when an end device has answered.

Embodiment 2

[0025] Such as figure 2 As shown, the master control node broadcasts the polled terminal device list (the polled terminal device list can also be stored in the terminal device in advance), and the polled terminal device list contains the response sequence and data protection interval of each terminal device Duration; the master control node broadcasts the polling start response command to all terminal devices, and the polling start response command contains the serial number of the first terminal device that responds; the terminal devices respond in turn, and the specific implementation is: specified in the polling start response command The terminal device that responds first responds immediately, and the other terminal devices respond in turn according to the response order specified in the polled terminal device list, more specifically, the polling start response command specified in the polled terminal device list After the terminal device specified in the first response ...

Abstract

The invention provides a point-to-multipoint polling communication method. A master node transmits a polling start response command to a terminal device; upon receipt of the polling start response command, the terminal device makes sequential responses according to a pre-acquired response sequence provided in a list of terminal devices under polling; alternatively, the polling start response command comprises a serial number of a terminal device that makes response first, the terminal device corresponding to the serial number responds first, other terminal devices respond according to the response sequence provided in the list of terminal devices under polling when monitoring that the terminal device ahead finishes responding. The point-to-multipoint polling communication method has high polling efficiency, and may provide greatly improved efficiency to the case where mass identical important data need to be transmitted to clients and there is a need for the clients to respond.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a point-to-multipoint polling communication method. Background technique [0002] The traditional polling and answering method mainly adopts the method that the master control node inquires sequentially according to the polling list, and the client responds after receiving the inquiry command, that is, the master control node sends the query data command to the first client → the first client terminal response; the master control node sends a query data command to the second client → the second client responds... until the master control node sends a query data command to the Nth client → the Nth client responds. [0003] The invention patent of application number 02131775.5 provides a polling scheduling method for equipment data, which adopts the following steps: A. Read equipment data, classify all equipment according to their types and internal modules, and a...
