Product Description

First, the working principle of the doorbell
1. The wireless signal receiver receives the wireless voice or video signal from the outdoor unit, the main processor performs redundancy and decoding processing on the received signal, and then displays the decoded video signal through the display screen, and the decoded voice signal is The D/A is converted to an analog signal and played out through the speaker.
2. Send the control signals generated by various peripherals of the indoor unit, such as call and unlock buttons, through the wireless signal transmitter.
3.Use the microphone to collect the voice signal, and convert the collected analog signal into digital signal. The main processor compresses the voice signal, and then transmits the compressed signal through the wireless signal transmitter.

Second, the doorbell does not ring how to repair
1. The professional leader of the maintenance worker in the engineering class repairs the doorbell of the household.
2. Maintenance workers must come to the door for maintenance within 10 minutes after receiving the dispatch order.
3. If the walkie-talkie does not ring and the walkie-talkie does not transmit, it can be determined that the walkie-talkie is broken. The maintenance method is to disassemble the walkie-talkie, check whether the five common lines inside are falling off or have poor contact, and focus on checking whether the ringing line is broken. After the problem is found, use solder to fix the loose line.
4. Maintenance method for the failure of the host: disassemble the host, check whether the "host input line" is off and whether the main engine core is burned. After the problem is found, it can be connected between the host "public line" and "host input line". Just add a resistor or replace the main engine core.
5. If the main household cannot open the anti-theft door to the main unit, the maintenance method is: turn on the main unit, remove the "opening wire", and then put the "opening wire" on the original fixing piece, if there is a door opening sound at this time, It can be concluded that a walkie-talkie in this unit is broken, and finally the bad walkie-talkie can be found and repaired or replaced.
6. The electromagnetic coil of the anti-theft lock is burned out, and it can be replaced during maintenance.

It can be seen that the working principle of the doorbell is not complicated. For example, the microphone is used to collect voice signals, and the collected analog signals are converted into digital signals. The main processor compresses the voice signals, and then transmits the compressed signals through wireless signals. launcher.
