Detailed Description
The invention provides a method and a system for realizing communication between a public network interphone and a DMR interphone, and the invention is further described in detail below in order to make the purpose, the technical scheme and the effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the prior art, the public network interphone and the DMR interphone cannot communicate with each other due to the fact that the built-in communication modules of the public network interphone and the DMR interphone are different, and therefore the application range of the DMR interphone is severely limited.
Based on the problems existing in the prior art, the invention provides a method for realizing the communication between a public network interphone and a DMR interphone, which is applied to a system for realizing the communication between the public network interphone and the DMR interphone, wherein the system comprises the DMR interphone, the first public network interphone and a second public network interphone provided with a DMR module, and as shown in figure 1, the method comprises the following steps:
s10, the second public network interphone receives the DMR signal sent by the DMR interphone;
and S20, the second public network interphone converts the received DMR signal into a public network signal and sends the public network signal to the first public network interphone, so that the first public network interphone and the DMR interphone establish one-way communication.
Specifically, the DMR interphone supports voice communication, data transmission and other supplementary services, and the DMR standard improves the spectrum utilization rate, which brings greater communication capacity to the DMR interphone, improves the communication efficiency, saves the use cost, and enables users to obtain more clear, reliable, more convenient and efficient wireless communication services; however, the effective communication range of the DMR interphone is very small, usually only several kilometers, and no signal can be received by each other beyond this range; under the condition that the public network interphones have networks, the communication range between the public network interphones is not limited by distance, but the use cost of the public network interphones is higher. The public network interphone and the DMR interphone have advantages and disadvantages and are suitable for application scenes, however, under certain application scenes that cost needs to be saved, communication between the DMR interphone and the public network interphone needs to be established, but the prior art cannot realize communication between the DMR interphone and the public network interphone.
In this embodiment, the DMR module is disposed in the second public network interphone, and the distance between the second public network interphone and the DMR interphone is within the effective communication range, in this embodiment, the second public network interphone with the DMR module is used as a bridge between the first public network interphone and the DMR interphone, so that the one-way communication between the first public network interphone and the DMR interphone can be realized, that is, the first public network interphone can receive and hear the voice sent by the DMR interphone in one direction, thereby expanding the application scenario of the DMR interphone and facilitating the use of the DMR interphone for users.
In some embodiments, as shown in fig. 2, the method for implementing communication between the public network interphone and the DMR interphone further includes the steps of:
s100, the second public network interphone receives a public network signal sent by the first public network interphone;
s200, the second public network interphone converts the received public network signals into DMR signals and sends the DMR signals to the DMR interphone, so that the first public network interphone and the DMR interphone establish two-way communication.
The method for realizing communication between the public network interphone and the DMR interphone provided by this embodiment is suitable for a fixed scene, for example, a user carries the DMR interphone to perform task search in an environment (in a mountain forest) without a public network, and at this time, the DMR interphone generally needs to communicate with a first public network interphone which is located in a public network environment at a long distance to report the search condition. In the fixed scene, because the prior art can not realize the communication between the DMR interphone and the public network interphone, the prior public network interphone and the DMR interphone can not be used in the scene, and the use is limited. In the method for implementing communication between the public network interphone and the DMR interphone provided in this embodiment, the second public network interphone with the DMR module is used as a bridge between the first public network interphone and the DMR interphone, and the distance between the second public network interphone and the DMR interphone is within an effective communication range of the first public network interphone and the DMR interphone, so that the second public network interphone can convert the DMR signal sent by the DMR interphone into a public network signal and send the public network signal to the first public network interphone, and the first public network interphone can receive and hear the voice sent by the DMR interphone; meanwhile, the second public network interphone can also convert public network signals sent by the first public network interphone into DMR signals and send the DMR signals to the DMR interphone, so that the DMR interphone can receive and listen to voice sent by the first public network interphone. That is to say, in this embodiment, the second public network interphone including the DMR module is arranged in the effective communication range of the DMR interphone, so that the two-way communication between the first public network interphone and the DMR interphone can be realized, thereby extending the application scenarios of the DMR interphone and the public network interphone, and providing convenience for users to use the DMR interphone.
In some specific embodiments, the step of receiving, by the second public network interphone, the DMR signal sent by the DMR interphone includes: the DMR interphone sends the voice sent by the user to the second public network interphone in the form of a DMR signal; and the second public network interphone analyzes the DMR signal into voice according to a built-in DMR module and plays the voice through a loudspeaker.
In this embodiment, since the DMR module is disposed in the second public network interphone, the second public network interphone can analyze the DMR signal sent by the DMR interphone into a voice sent by the user and play the voice. The DMR interphone can better inhibit noise, and has higher voice quality than an analog technology especially at the edge of a coverage range; the DMR improves the effective coverage of wireless communications, and thus users can freely cope with the changing working situation. One major advantage of DMR walkie-talkies is that a single 12.5kHz channel can be made to support 2 simultaneous or independent conversations. In the DMR standard, Time Division Multiple Access (TDMA) may reserve a 12.5kHz bandwidth and divide it into 2 alternating time slots. Each time slot can operate as a separate communication channel and have an equivalent bandwidth (6.25kHz), the original channel can still maintain the same configuration as the analog 12.5kHz signal. This means that the DMR is fully compatible with existing licensed PMR frequency points, thus eliminating the need to reconfigure or repurchase frequency points, while doubling the capacity of the 12.5kHz bandwidth. Another advantage of DMR walkie-talkie is that only one repeater, one antenna and one duplexer are needed to have two channels, which does not require additional repeaters or combination devices, which means that DMR users' cost can be reduced and their networking scheme simplified; the DMR interphone also has the advantages of longer service life of the battery and strong communication privacy.
In some specific embodiments, the step of converting the received DMR signal into a public network signal and sending the public network signal to the first public network interphone by the second public network interphone, so that the first public network interphone establishes unidirectional communication with the DMR interphone includes: the second public network interphone picks up the voice through a built-in sound pick-up device, converts the voice into a public network signal and sends the public network signal to the first public network interphone; the first public network interphone analyzes the received public network signals into voice and plays the voice through a loudspeaker, so that the first public network interphone and the DMR interphone establish one-way communication.
In some embodiments, the step of the second public network interphone sending the public network signal to the first public network interphone comprises: the second public network interphone sends the public network signal to a server through a public network; and the server sends the public network signal to the first public network interphone through a public network.
In some embodiments, the step of receiving, by the second public network interphone, the public network signal transmitted by the first public network interphone includes: the first public network interphone sends the voice sent by the user to the second public network interphone in a public network signal mode; and the second public network interphone analyzes the received public network signal into voice and plays the voice through a loudspeaker.
In some embodiments, the step of converting the received public network signal into a DMR signal by the second public network interphone, and sending the DMR signal to the DMR interphone, so that the first public network interphone establishes two-way communication with the DMR interphone includes: the second public network interphone picks up the voice through a built-in sound pick-up and converts the voice into a DMR signal through a built-in DMR module to be sent to the DMR interphone; the DMR interphone analyzes the received DMR signal into voice and plays the voice through a loudspeaker, so that the first public network interphone and the DMR interphone establish two-way communication.
