Abstract

The invention discloses a device management method based on self-adaptive polling. According to the method, starting with two aspects of polling response and message sending response, the reply time of the polling is dynamically adjusted according to a set range, thereby adapting to the reply time of different data and devices; the set pooling interval time is adjusted according to the set range, so the pooling waiting time is reduced; the polling expired time is dynamically adjusted according to the set range, so a loss probability is reduced; connection lost sub-devices can be dynamically jumped, so the number of valid pooling times is improved; and a data sending success rate is effectively improved according to the set smart adjustment retransmission times, thereby self-adaptively adjusting the polling time and frequency.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device management method based on adaptive polling. Background technique [0002] In the existing technology, the RS485 communication protocol is a widely used communication protocol standard. The electrical characteristics of RS-485: the negative logic of the differential signal is used, and the logic "1" is expressed by the voltage difference between the two lines as - (2 ~ 6) V ;Logic "0" is represented by the voltage difference between the two lines as +(2~6)V. The RS485 interface is a combination of a balanced driver and a differential receiver, which enhances the ability to resist common-mode interference, that is, it has good anti-noise interference. The RS485 communication protocol in the prior art mostly adopts polling mode to access and exchange data with sub-equipment. Since the polling time is fixed and the efficiency is low, the polling time and frequency ...
