The working principle is described in the following parts:
a first part: call establishment section
1.1 establishing a call by the secondary 22.
This is the vast majority of call situations, i.e. an elevator encounters an emergency and needs to establish an emergency call. At this time, any one of the auxiliary devices 22 can press the alarm key, the alarm key loads a dual-tone multi-frequency signal 'DTMF tone-8' on the two-line voice interface 15 (at the same time, the host 21 also receives the dual-tone multi-frequency signal through the two-line voice interface 15 and rings, the host 21 goes off the hook and can communicate with the auxiliary device 22), the voice module 14 receives the dual-tone multi-frequency signal 'DTMF tone-8' sent by the two-line voice interface 15 and forwards the dual-tone multi-frequency signal 'DTMF tone-8' to the dual-tone multi-frequency receiver 13, the dual-tone multi-frequency receiver 13 analyzes the dual-tone multi-frequency signal 'DTMF tone-8', sends a digital signal to the controller 11, and the controller 11 controls the communication module 12 to dial a prestored number according to the.
After the call is put through, the mobile phone B of the maintenance person can establish contact with the communication module 12 (generally, the 4g or 5g communication module 12), the communication module 12 converts the received remote signal into voice and sends the voice to the voice module 14, and the voice module 14 adjusts the voice into an analog audio signal which is in point adaptation with the two-wire voice interface 15 and sends the analog audio signal to the host 21 and the auxiliary 22.
If the sub-unit 22 continuously presses the alarm key for more than 6 times, 6 dual tone multi-frequency signals "DTMF tone-8" are generated, and the controller 11 receives the digital signals for more than one time and controls the communication module 12 to dial 110A according to the above principle.
1.2 on-hook procedure
On the basis of 1.1, the host 21 and the auxiliary 22 hang up to generate another dual tone multi-frequency signal such as 'DTMF tone-0', at this time, the same signal is digitized and then reaches the controller 11, the controller 11 counts whether all the host 21 and the auxiliary 22 hang up, and if the host hangs up, the communication module 12 is controlled to disconnect the remote connection with the mobile phone B.
And the hanging up of the remote handset B does not affect the communication connection between the main unit 21 and the auxiliary unit 22.
1.3 establishing a call connection by remote handset B
The remote collection dials the communication module 12, the communication module 12 generates a dual tone multi-frequency signal 'DTMF tone-8' after being switched on, the dual tone multi-frequency signal 'DTMF tone-8' is sent to the voice module 14 through the analog audio input interface, the voice module 14 sends voice to the two-wire voice interface 15, and the host 21 and the auxiliary 22 receive the dual tone multi-frequency signal 'DTMF tone-8' and ring.
