The invention discloses a LoRa-based elevator external calling system which comprises external calling boards, LoRa base stations, elevators and an elevator controller, the external calling boards are installed on the outer walls of all floors of an elevator shaft, LoRa chips and distance sensors are embedded in the external calling boards, the LoRa base stations are arranged in all the elevators, the distance sensors are installed on elevator cars, and the LoRa chips are embedded in the LoRa base stations. The external calling board is in wireless communication with the LoRa base station through the LoRa chip, and the LoRa base station and the elevator are in communication connection with the elevator controller. The external calling board is used for generating an external calling signal according to a passenger external calling request and sending the external calling signal to the LoRa base station, the LoRa base station is used for sending the external calling signal of each floor to the elevator controller, and the elevator controller is used for determining a calling floor according to the external calling signal to dispatch an elevator and control the elevator to run; and the elevator running state information is sent to the outer calling board of each floor through the Lora base station. The cable wiring cost is remarkably reduced.
本发明公开了一种基于LoRa的电梯外召唤系统,包括外召唤板、LoRa基站、电梯和电梯控制器,外召唤板安装于电梯井道每一楼层外墙上,外召唤板内嵌设有LoRa芯片和距离感应器,LoRa基站设置于每一台电梯内,且电梯轿厢安装有距离感应器,外召唤板通过LoRa芯片与LoRa基站进行无线通讯,LoRa基站和电梯分别与电梯控制器通讯连接;外召唤板用于根据乘客外召唤请求生成外召唤信号并发送至LoRa基站,LoRa基站用于将各楼层外召唤信号发送至电梯控制器,电梯控制器用于根据外召唤信号确定召唤楼层对电梯进行调度控制电梯运行,并将电梯运行状态信息通过Lora基站发送至各楼层外召唤板。本发明显著减少电缆布线成本。
