[0002] At present, it is more common for the display in the elevator car to collect floor and direction signals through the elevator protocol, obtain floor data from the elevator display interface and then display it. The elevator communication protocol is a protocol that stipulates the information exchange between the elevator and other equipment and systems. It defines the data format, communication process, error handling and other specifications to ensure smooth communication between the elevator and other systems. Therefore, the communication protocol of the elevator system must be obtained to obtain information such as floor and direction. Generally speaking, different brands of elevators and systems have different communication interfaces and protocols. In order to adapt to different brands of elevators and systems, different communication software needs to be developed; and elevators of the same brand but different systems also need to be adapted according to different protocols.
[0003] However, the communication protocol of the elevator system is generally not open to the outside world, and different elevator systems have different communication protocols. In order to adapt to different elevator systems, the display device must correspond to different communication software, which greatly increases the difficulty and workload of development work. At the same time, the communication between the floor display device and the elevator system requires a communication cable to connect, which increases the risk of failure. Utility Model Content
