Background
With the continuous development of network technology, enterprises can improve productivity and customer satisfaction by realizing real-time communication between associated objects to generate real-time big data and then analyzing and converting the data, thereby establishing a vertically and horizontally staggered business partner relationship in a larger range and improving enterprise competitiveness.
The main technology in the current market is a DTU or an intelligent gateway, and data of an intelligent ammeter or a sensor can be acquired through RS 485.
The DTU mostly adopts wireless transmission, does not support breakpoint continuous transmission, has limited number of accessible intelligent devices, and is slow in response or even free of response when the number of accesses is more than 15 and the acquisition frequency is equal to 1 minute, so that data loss is caused. The DTU only conducts transparent transmission between the data and the platform because the DTU does not store the data, so that the data is not completely uploaded in some areas with poor signals and is not stored locally, and continuous transmission can not be conducted after the signals are recovered, so that partial data are lost.
The intelligent gateway can simultaneously support wireless and wired, simultaneously supports breakpoint continuous transmission, the number of accesses is far higher than DTU, but when different devices are accessed, complicated protocols and parameter configuration are needed to be carried out and the devices are written in, and as the gateway device does not have fixed ip, if parameter change is met, only local configuration can be carried out, remote upgrading cannot be carried out, and therefore the maintenance cost is greatly increased. The configuration of the gateway is complicated, mainly for flexibility, the definition authority of the gateway is granted to the user, but higher requirements are put forward for the user, and the access efficiency is greatly reduced.
