Other AbstractThe invention relates to a TDMA (Time Division Multiple Address) accessing device and a TDMA accessing method based on multiple access points. Aiming at the problems that in the prior art, the requirements of the actual industrial application on real-time performance and reliability cannot be met and the utilization rate of resources is low, etc, the invention provides the TDMA accessing device and the TDMA accessing method based on the multiple access points after the full consideration on the transmission characteristics of a wireless network and the characteristics of an industrial automation application. The method has the main thoughts that the reliability of the system is improved through the adoption of a multi-access-point redundancy communication mode; time synchronization is carried out through the utilization of the beacon frames of the multiple access points so as to improve synchronization accuracy; a confirmation message is replied on account of the reliable access points to reduce retransmission times; the maintenance and management difficulty of the device is lowered by a design method adopting a modular multi-access-point device.
