Technical Field
The invention relates to the technical field of firmware upgrading, in particular to an intelligent platform software upgrading method based on BACnet.
Background
BACnet is a communication protocol for smart buildings, and is also a communication protocol defined by the international organization for standardization (ISO), American National Standards Institute (ANSI), and american society of heating, cooling, and air conditioning engineers (ASHRAE). BACnet is designed for communication in applications of intelligent buildings and control systems, and can be used in heating, ventilation and air conditioning (HVAC) systems, as well as lighting control, access control systems, fire detection systems, and related devices. As shown in fig. 1, a plurality of BACnet devices can be simultaneously accessed in one BACnet network, and the devices adopting the BACnet system cannot be directly upgraded through online firmware of the network at present, and cannot rapidly repair bug of the product, so that the building system is relatively large, and the cost for loading, unloading and returning to the factory is too high, and therefore, the BACnet network can only be supported by home maintenance.
The main reasons for the above problems are: the BACnet protocol has no definite upgrading process, the network environment is relatively severe, interference influence factors (electromagnetic interference, radiation interference and power grid interference) are easily received too much, and the stability and reliability of the transmission process cannot be ensured, so that the BACnet protocol product cannot be directly upgraded through the conventional BACnet network.
Therefore, the inventor especially develops the BACnet-based intelligent platform software upgrading method to improve the upgrading efficiency and reduce the maintenance cost.
