Wireless access building service device and its automatic networking method

Abstract

The invention discloses a wireless accessing building service device and a self-networking method thereof and relates to relay transmission and a processing device of wired / wireless information and a networking method thereof. The wireless accessing building service device is provided with a plurality of wireless terminals, a coding chip, a light-emitting diode (LED) lamp, a keyboard, a wire jumper circuit, a power supply circuit and a wireless communication module are arranged in each wireless terminal. The wireless accessing building service device is further provided with a wired supervisor and a plurality of wired / wireless repeaters, wherein the plurality of wired / wireless repeaters is in parallel connection with an input / output (I / O) interface of the wired supervisor, an I / O interface is arranged on each wired / wireless repeater and correspondingly connected with the I / O interface of the wired supervisor through multicore cables, and a wireless communication module is arranged on each wired supervisor and in wireless connection with wireless communication modules of the adjacent wireless terminals. The wireless accessing building service device is flexible and convenient to apply and low in cost.

Description

technical field [0001] The invention relates to a device for transmitting and processing call service information and a networking method thereof, in particular to a relay transmission and processing device for wired / wireless information and a networking method thereof. Background technique [0002] The existing catering service, restaurant service, hospital call service and other building service call systems usually use figure 1 The transmission and processing device of the wired information shown or figure 2 The wireless information relay transmission and processing device shown. [0003] figure 1 In the shown wired information transmission and processing device, the wired management machine 1 is provided with multiple I / O interfaces, and each I / O interface communicates data with a specific wired terminal 2 via an independent multi-core cable 4 . Each wired terminal 2 is provided with a single-chip microcomputer, a power supply circuit, a display, a keyboard, and a wi...

AI Technical Summary

Problems solved by technology

(1), the wireless environment in the building is too complicated, so there are often some places where the wireless communication is not good, and the wireless relay station 30 has to be added. The use of the wireless relay station 30 is expensive, and the wireless management machine 10, the wireless terminal 20, The wireless communication module of wireless relay station 30 all adopts 2.4G digital transmission module or ZigBee module (a pair needs nearly 100 yuan), the second is for the requirement of radio frequency safety, wireless management machine 10, wireless terminal 20, wireless relay station 30 The power of the communication module should not be too large, and the communication distance is limited. Usually, the straight-line transmission distance is within 100 meters

(2), the wireless terminal 20 bound to a certain wireless relay station 30 takes another location or room, and cannot call without the support of the wireless relay station 30; the networking is inflexible

(3), during network debugging, each wireless terminal 20 is numbered and set to use an electric soldering iron to weld or fuse the jumper circuit 22 of the wireless terminal 20 on the spot, and then operate the wireless terminal 20 and the wireless management machine 10 or wireless Relay station 30, so that they form a binding, the binding operation is too professional and inconvenient
