The invention relates to the technical field of communication, in particular to a hotel door display control device based on RS485 bus communication. The hotel door display control device based on RS485 bus communication comprises a central controller, a guest room inner control end, a doorplate display controller and a guest room doorplate. The guest room inner control end is used for receiving a control instruction of a resident in a guest room, analyzing the control instruction and transmitting the analyzed control instruction to the doorplate display controller through an RS485 bus, and the doorplate display controller adjusts the display content of a guest room doorplate according to the analyzed control instruction; and the guest room inner control end is also used for reporting the current display content of the guest room doorplate to the central controller through an RS485 bus. The stability of hotel internal data transmission is improved, the influence of external environmental factors on data transmission is reduced, the load of the central controller is reduced, and the utilization rate of edge computing resources is improved.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a hotel door display control device based on RS485 bus communication. Background technique [0002] Hotel room accommodation is a basic need for people's daily travel. The hotel management needs a stable and reliable room management system to control the information interaction between the hotel front desk and each room. The hotel door display control device is a display and control device used in the hotel room number plate inside the hotel. [0003] The current hotel door display control devices mostly use wireless communication to realize the transmission of house number control signals, and mostly use centralized information processing methods to centralize the room number control information to the central processor for processing, and then control the room number . However, the wireless communication method is greatly affected by environmental factors such as heavy...
