Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that all the directional indicators (such as upper, lower, left, right, front, back, inner and outer, and the center … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
In the present application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., "fixed" may be fixedly connected or detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In addition, the technical solutions between the embodiments of the present invention can be combined with each other, but it is necessary to be able to be realized by a person having ordinary skill in the art as a basis, and when the technical solutions are contradictory or cannot be realized, the combination of such technical solutions should be considered to be absent, and is not within the protection scope of the present invention.
Example 1:
as shown in fig. 1, the dual-mode group dialing system with PSTN and 4G comprises a main control board 1, an integrated power management circuit 3 electrically connected to a power port 2 of the main control board 1, a 4G switch 5 electrically connected to a 4G unit 4 of the main control board 1, a peripheral WIFI6 electrically connected to the main control board 1, and an MCU controller 8 electrically connected to a UART interface 7 of the main control board 1; the device also comprises a PSTN chip 10 electrically connected with the GPIO interface 9 of the MCU controller 8; the system also comprises a stored program control exchanger 12 connected with the RJ11 interface 11 of the PSTN chip 10; and a touch panel 13 connected to the main control board 1.
Further preferably, the integrated power management circuit 3 is mainly used to manage the power devices in the main control board.
Preferably, the SPK port of the PSTN chip 10 is connected with a speaker switch 14; the MIC interface of the PSTN chip 10 is connected with a microphone switch 15; the loudspeaker switch 14 is also electrically connected with a loudspeaker 16, and the microphone switch 15 is also electrically connected with a microphone 17; preferably, an earpiece 18 connected to the microphone switch 15; the MIC port of the receiver 18 is electrically connected with the microphone switch 15, and the SPK port of the receiver is connected with the loudspeaker switch 14; input and output of sound are realized by the speaker 16 and the microphone 17; the PSTN chip, as a public switched telephone network, is a circuit switched service based on standard telephone lines, used as a connection to connect remote endpoints.
It should be noted that the working principle of the present embodiment is as follows:
when the dialing system dials in the PSTN mode, the main control panel 1 acquires the state of the receiver 18, the receiver 18 off-hook or the hands-free off-hook is sent to the MCU controller 8 according to the state of the receiver 18, after an off-hook signal is sent, the main control panel 1 writes the number to be dialed by a user into the MCU controller, the MCU controller 8 transmits data to the RJ11 interface 11, namely a telephone line jack, and then transfers the data to the upper side of the stored program control switch 12, and the stored program control switch 12 transfers the data to the China telecommunication network to complete dialing in the PSTN mode;
