Background

The vehicle-mounted station is a wireless interphone which can be mounted on vehicles such as vehicles, ships and airplanes, is directly powered by an external power supply and uses an external antenna. The method is mainly used for traffic transportation, production scheduling, security command and other services. It is bulky. The power is not less than 10W, and is generally 25W. The maximum power is VHF 56W, UHF 50W. Also the power of the individual vehicle stations in a certain frequency band reaches 75W. The power supply of the vehicle-mounted interphone is 13.8V, and the transmitting power of the vehicle-mounted interphone is large, so that the communication distance is far longer than that of a conventional handheld interphone. The communication distance can reach more than 20 kilometers, and in a wireless communication network, the communication distance is obviously increased through the transfer platform and can reach dozens of kilometers. The vehicle-mounted platform has the characteristics that: the transmitting power is large, and the communication distance is long.

The user's demand for the voice intercommunication between the frequency bands and between the analog and digital terminals is becoming stronger, and the solution is presented to solve the user's demand for the voice intercommunication between the frequency bands and between the analog and digital terminals. When a user is in two different frequency bands or cannot complete a normal voice intercommunication module when the user holds an analog terminal and a digital terminal respectively in some environments, the user needs a scheme to solve the communication problem urgently and guarantee the service and the quality of communication, so that the back-to-back system solution of the vehicle-mounted station is promoted.

An object of the utility model is to provide an application based on vehicle-mounted platform tail needle module definition has the vehicle-mounted platform back-to-back system of nimble operability to solve the problem that proposes among the above-mentioned background.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a vehicle-mounted platform system back-to-back, includes two vehicle-mounted platforms that link to each other with PIN mouth connecting wire, two vehicle-mounted platforms that link to each other with PIN mouth connecting wire all are equipped with tail needle input module and tail needle output module, tail needle input module contains tail needle PTT input and the outside MIC signal input of tail needle. The tail pin output module comprises a loudspeaker opening detection and an audio output.

Preferably, the tail pin input module can trigger starting or stopping transmission through the tail pin no matter in a digital channel or an analog channel, and simultaneously samples the voice information to be transmitted from the corresponding input pin.

Preferably, the tail pin output module can output the state of whether the voice is currently received through the tail pin in the form of level in a digital channel and an analog channel, and simultaneously output the currently received voice content.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses application based on vehicle-mounted platform tail needle module definition has nimble operability, through the design that PIN mouth connecting wire links to each other two vehicle-mounted platforms, can realize striding terminal speech intercommunication and the speech intercommunication between simulation and digital terminal between the frequency band.

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 work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a vehicle-mounted platform system back-to-back, includes two vehicle-mounted platforms that link to each other with PIN mouth connecting wire, two vehicle-mounted platforms that link to each other with PIN mouth connecting wire all are equipped with tail needle input module and tail needle output module, tail needle input module contains tail needle PTT input and the outside MIC signal input of tail needle. The tail pin output module comprises a loudspeaker opening detection and an audio output. The tail pin input module can be triggered to start or stop transmitting through the tail pin no matter in a digital channel or an analog channel, and simultaneously samples voice information to be transmitted from a corresponding input pin; the tail pin output module can output the current state of receiving voice through the tail pin in the form of level in a digital channel and an analog channel, and simultaneously, the current received voice content

And a tail pin input module of the vehicle-mounted station triggers starting or stopping transmission through a tail pin, and simultaneously samples the voice information to be transmitted from a corresponding input pin. When the outside inputs an effective level, the host computer opens the emission path, opens the outer Mic of the tail pin at the same time, and emits the sampled audio data. When the input level is invalid, the host stops transmitting, the Mic outside the tail pin is used as an external voice information source, and when the PTT of the tail pin is valid, the host enters a transmitting state and transmits the voice signal of the pin; the tail needle output module of the vehicle-mounted station outputs the current state of whether receiving the voice in the digital channel and the analog channel in the form of level through the tail needle, outputs the current received voice content at the same time, opens the detection pin through the loudspeaker, outputs the effective level when the host computer detects to open the loudspeaker, outputs the invalid level after closing the loudspeaker, and when the host computer receives the voice service, broadcasts the received voice through the tail needle through the audio output pin.

Working principle; as shown in fig. 2, when the intercom 1 starts to transmit, the intercom 2, the intercom 3 and the vehicle-mounted station 1 receive signals at the same time. After receiving the carrier wave, the vehicle-mounted platform 1 outputs the audio signal to the vehicle-mounted platform 2 connected with the vehicle-mounted platform through the PIN port, and activates the external Mic PTT of the vehicle-mounted platform 2; the vehicle-mounted station 2 starts transmission (wired audio signal transmission is adopted between the vehicle-mounted station 1 and the vehicle-mounted station 2, and the influence of two vehicle-mounted station working modes (digital and analog) and frequency is avoided).

The interphone 4, the interphone 5 and the interphone 6 in the communication range of the vehicle-mounted platform 2 simultaneously receive the same audio signal as the vehicle-mounted platform 1, and the interphone 1 completes communication with the interphone 4, the interphone 5 and the interphone 6. The vehicle-mounted station 2 can also transmit the audio signal to the vehicle-mounted station 1 through the PIN port (the reference device is connected), so that intercommunication between the two interphones in the communication range of the vehicle-mounted station is realized.
