Interphone system and use method thereof

Abstract

The invention provides an interphone system. The system comprises an interphone, a Bluetooth module, a Bluetooth PTT and a Bluetooth device. The interphone comprises a microprocessor, an audio channelconnected with the microprocessor, a Bluetooth module interface connected with the microprocessor and the audio channel, and a transmitting module connected with the audio channel. Both the BluetoothPTT and the Bluetooth device can be adaptively connected with the Bluetooth module. The Bluetooth module works in a master mode, and the Bluetooth PTT and the Bluetooth device work in a slave mode. The Bluetooth PTT is used for controlling the emission of the interphone, and the Bluetooth device is used for collecting a voice signal to be sent and playing the received voice signal. The inventionalso provides a use method of the interphone system. According to the invention, a user can complete a call without holding the interphone by hand, and does not need to press the Bluetooth PTT all thetime, thereby avoiding the loss of the voice signal as much as possible, and improving the satisfaction degree of the user experience.

Description

technical field [0001] The present invention relates to a walkie-talkie system and a method of using the same. Background technique [0002] As a two-way mobile communication tool, walkie-talkies are widely used in the transportation industry and self-driving tours. However, the walkie-talkie needs to press the PTT voice transmission button when sending voice, which will occupy one hand and pose a great safety risk when driving. [0003] It is common for existing mobile phones to connect to Bluetooth devices such as car Bluetooth audio systems and Bluetooth headsets, which are widely used in life. The biggest difference between connecting bluetooth devices is that the phone calls or outgoing calls have to pick up the phone to answer or wait for the other party to answer the ringtone as a buffer time, but the walkie-talkie is an instant communication product, which has the characteristics of one-touch talk and one-receive listening, so when a walkie-talkie After connecting ...

However, the walkie-talkie needs to press the PTT voice transmission button when sending voice, which will occupy one hand, and there is a great safety risk when driving

[0003] It is common for existing mobile phones to connect to Bluetooth devices such as car Bluetooth audio systems and Bluetooth headsets, which are widely used in daily life, but it is not common to connect walkie-talkies to Bluetooth devices such as car Bluetooth audio systems and Bluetooth headsets. The biggest difference between connecting to a Bluetooth device is that there is a ringtone for answering or waiting for the other party to answer an incoming or outgoing call from a mobile phone as a buffer time. After connecting Bluetooth devices such as car Bluetooth audio system and Bluetooth headset, you will encounter the following series of problems that are completely different from mobile phone connections: 1. The performance of existing Bluetooth devices is uneven, and some Bluetooth devices with poor performance will There is a defect that the audio channel is opened slowly, which will cause the loss of the voice signal during the call; 2. After the user is connected to the walkie-talkie, he usually connects to the Bluetooth device to play music when the call is not in progress. Of course, the voice call of the walkie-talkie has Priority, but due to the characteristics of the walkie-talkie, when the Bluetooth PTT is triggered by mistake and the instantaneous signal is caused, the music playback will be interrupted. This kind of problem is easy to appear repeatedly, which will cause poor user experience. 3. In the existing technology, the Bluetooth PTT is fixed on the steering wheel. Generally, the intercom can be performed after pressing and holding it, and the intercom ends after releasing it. However, the driver needs to operate the steering wheel. At this time, press and hold the Bluetooth PTT , so that there is a very high risk of driving; 4. The existing Bluetooth PTT has a built-in lithium battery with a small capacity. It takes a certain amount of time to start up again, which may easily cause the loss of voice signals; 5. When talking, you need to hold the walkie-talkie
