An elevator communication type five-party talkback system comprises a car roof talkback device, a car talkback device, a pit talkback device, a machine room talkback device and a monitoring room talkback device. The car roof talkback device, the machine room talkback device and the monitoring room talkback device each comprise a controller, a CAN bus communication module, an acoustic-electric conversion module and an electro-acoustic conversion module. And the car intercom device is in communication connection with the car roof controller. The car roof talkback device, the pit talkback device and the machine room talkback device convert analog audio signals into digital audio data and then send the digital audio data to the CAN bus of the elevator to be transmitted, conversation is achieved, conversation lines in accompanying cables are omitted, the system cost and wiring complexity are reduced, harmonic interference in the elevator environment is not prone to occurring, and the safety of the elevator is improved. And the call quality is improved.
一种电梯通讯式五方对讲系统,包括轿顶对讲装置、轿厢对讲装置、底坑对讲装置、机房对讲装置和监控室对讲装置。轿顶对讲装置、机房对讲装置和监控室对讲装置均包括控制器、CAN总线通信模块、声电转换模块和电声转换模块。轿厢对讲装置与轿顶控制器通信连接。轿顶对讲装置、底坑对讲装置、机房对讲装置将模拟音频信号转换成数字音频数据后发送到电梯的CAN总线上传送,实现通话,不仅省去了随行线缆中的通话线,降低了系统成本与布线复杂度,而且在电梯环境中不易受到谐波干扰,提高了通话质量。
