[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1 As shown, the present invention provides a technical solution: an industrial smart phone suitable for harsh environments, including an intrinsically safe power supply, a digital-analog circuit, a digital-analog self-identification switching module, an intelligent CPU mainboard, a high-quality audio amplifier module, an external intrinsically safe speaker, a light-sensitive touch waterproof keyboard, a waterproof anti-noise microphone, a phone handle and a phone display screen, the digital-analog self-identification switching module is reserved with a wiring terminal and a wiring terminal, and the intrinsically safe power supply is connected to the wiring terminal, the intrinsically safe power supply is powered by the wiring terminal, the analog circuit or the digital circuit is connected to the wiring terminal of the digital-analog self-identification switching module through the digital-analog circuit, and the digital-analog self-identification switching module automatically After identifying and judging whether the line on the terminal is an analog signal or a digital signal, switch to the corresponding mode. After the corresponding mode conversion is completed, the signal is transmitted to the intelligent CPU mainboard for registration communication, and the intelligent CPU mainboard has a system-free self-organizing network communication function. The light-sensitive touch waterproof keyboard and the waterproof anti-noise microphone are reliable input devices of the phone, and the light-sensitive touch waterproof keyboard and the waterproof anti-noise microphone are connected to the intelligent CPU mainboard. The phone handle and the phone display are the call and display devices of the phone, and are connected to the intelligent CPU mainboard. The high-quality audio power amplifier module is provided with wiring terminals, and the high-quality audio power amplifier module is connected to the intelligent CPU mainboard.

[0020] The intelligent CPU motherboard transmits audio signals such as broadcast calls and music to the external intrinsically safe speaker through the wiring terminals on the high-quality audio amplifier module. When broadcasting music, you can press the emergency call button on the phone to make a call. At this time, the music will be paused and resumed when the call is finished, so that the phone in harsh environments has a broadcasting function; each group of unit keys of the optical touch waterproof keyboard is equipped with an optical touch chip, and a backlight is installed on the periphery of the optical touch chip to improve the reliability and anti-electromagnetic interference ability of the phone in extreme environments; the phone coexists with two modes based on the SIP communication protocol and the PSTN public switched telephone, which solves the problem that ordinary industrial telephones must be equipped with gateways or IP The phone can only make calls with a PBX and cannot be quickly deployed in a simple network environment; the phone handle, receiving / transmitting device, off-hook device and hands-free voice device are separated from the phone's operating device, display device, input / output interface and host circuit, and are installed in two independent closed spaces respectively. The protection level of the whole machine and the connection parts is not less than IP65, which solves the problem that ordinary industrial telephones have a high failure rate and poor call quality in harsh environments; the phone adopts a system-free calling mechanism, that is, multiple phones do not need to be registered without an IP PBX system, and users can define their own extension numbers and call each other's extension numbers, which reduces the equipment purchase volume and communication failure rate for customers.

[0021] It should be noted that an industrial smart phone suitable for harsh environments connects the intrinsically safe power supply to the wiring terminal of the digital-analog self-identification switching module when working. The intrinsically safe power supply uses the wiring terminal to power the phone, so that even if the power supply is short-circuited in harsh hazardous and explosive places, it will not cause electric sparks. There is no spark to cut off the danger source in the hazardous and explosive place. The analog line or digital line is connected to the wiring terminal of the digital-analog self-identification switching module through the digital-analog line. The digital-analog self-identification switching module automatically identifies and determines whether the line on the terminal is an analog signal or a digital signal based on the input signal, and switches to the corresponding mode based on the judgment. When the corresponding mode conversion is completed, the signal is transmitted to the intelligent CPU mainboard for registration communication, and the operator can operate on the input device of the phone. Since the input devices of the telephone are light-sensitive touch waterproof keyboard and waterproof anti-noise microphone, the reliability and anti-electromagnetic interference ability of the telephone in extreme environments can be improved in actual use. Among them, since the intelligent CPU motherboard has a system-free self-organizing network communication function, it can communicate with each telephone on the line without the need for external gateways and PBX and other equipment. When in use, the intrinsically safe speaker is connected to the telephone. At this time, the intelligent CPU motherboard can transmit audio signals such as broadcast calls and music to the external intrinsically safe speaker through the wiring terminals on the high-quality audio amplifier module. When the music is being broadcast, if a call comes in, you can press the emergency call button to make a call. At this time, the music will be paused and will continue to play when the call is over, so that the broadcast and phone can be switched freely.
