Problems solved by technology

[0003] Traditional analog intercoms use analog signals to transmit messages, which have defects such as low frequency utilization, serious interference, single business function, unstable communication, and difficult management and control. Analog intercoms generally use methods such as scrambling to encrypt information , has the defect of simple encryption and easy cracking
[0004] Faced with the above problems, digital walkie-talkies emerged as the times require. Although digital walkie-talkies can overcome most of the above-mentioned problems, the price of digital walkie-talkies is generally high, which affects their popularization.
[0005] Aiming at the technical problem of high cost of digital walkie-talkies in related technologies, no effective solution has been proposed yet

The intercom terminal comprises a shell; a hardware platform which is fixedly installed in the shell and provided with an Android system and used for operating an intercom application based on the Android system; multiple keys which are installed on the shell and connected with the hardware platform and used for realizing intercom operation in operation of the intercom application; a microphone which is installed on the shell and connected with the hardware platform and used for inputting voice information; and a loudspeaker which is installed on the shell and connected with the hardware platform and used for playing the voice information. The technical problems of high cost of the digital interphone in the related technologies can be solved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to an intercom terminal and a method and device for switching call modes. Background technique [0002] At present, domestic walkie-talkie production is still dominated by analog walkie-talkies. Analog walkie-talkies are a communication mode in which voice, signaling, and signals are modulated onto the carrier frequency of the walkie-talkie in a continuous wave manner, and optimized by amplification. Analog intercom has the characteristics of mature technology, perfect system, and relatively low cost. Domestic intercom products are only active in the middle and low-end market, and the phenomenon of cloning is serious, which is doomed to face a major crisis in the intercom industry. [0003] Traditional analog intercoms use analog signals to transmit messages, which have defects such as low frequency utilization, serious interference, single business function, unstable communica...
