Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0032] The overall structure diagram of the intelligent and convenient call terminal is as follows: figure 1 As shown, it includes: a wireless transmitting module, a wireless receiving module, a control module, an on-hook module, a dialing and signal detection module, a voice recording and playback module, and a mobile communication module. The wireless transmitting module is installed in the remote controller of the calling party, and the other six modules are all installed in the fixed telephone of the calling party or packaged as an independent module that can be connected with the telephone line.
[0033] The composition of the wireless transmitting module and the wireless receiving module is as follows: figure 2 shown.
[0034] The wireless transmitting module is composed of SC2262 infrared coding chip, 315MHz surface acoustic resonator, and key...

The invention discloses an intelligent and convenient calling terminal. A user only needs to press a key, and the user can simultaneously call a fixed-line telephone and a mobile phone respectively through a public telephone network and a mobile communication network. The intelligent and convenient calling terminal comprises a wireless transmitter module, a wireless receiver module, a control module, an on-hook and off-hook module, a dialing and signal detection module, a voice record-play module and a mobile communication module. According to the intelligent and convenient calling terminal, the advantages of the public telephone network and the mobile communication network are fully utilized, and by combining the two different communication networks, the problem that calling fails because the telephone is not answered on the opposite side or the line is busy is solved to some extent. The on-hook, off-hook, signal detection and voice sending operations are automatically completed through a telephone twisted pair, actual telephones are not required to be controlled, and the true one-touch calling is realized; an external pin on a global system for mobile (GSM) module is directly in circuit connection with a subscriber identity module (SIM) card to realize the basic function of communication of the mobile phone, and the mobile phone is not required to be actually controlled.
Description
technical field [0001] The present invention relates to fixed-line and mobile communication technologies, in particular to an intelligent and convenient calling terminal. A user can call a fixed-line phone and a mobile phone through a public telephone network and a mobile communication network at the same time only by pressing a button. Background technique [0002] my country is currently in the "Twelfth Five-Year Plan" period, and the construction of social security and public safety systems for urban and rural residents is still the focus of our country. With the improvement of people's living standards, people pay more attention to the quality of their own lives, and pay more attention to security services, an aspect closely related to people's daily life. With the rapid development of science and technology, intelligent systems and terminals will be more and more used in people's lives. [0003] Nowadays, industries related to intelligent systems and terminals are spri...
