The embodiment of the application provides a control method of locomotive wireless communication equipment, which is used for communicating with ground equipment by adopting different network systems, specifically, the locomotive passes through different sections in the running process, the network system improvement progress of each section is inconsistent, and part of sections adopt an advanced LTE-R/5G network system, but part of sections possibly use an analog network system. The locomotive wireless communication device aimed at by the embodiment can support communication with the ground device of a network system common in the railway system at present. The surface equipment may be surface equipment disposed at a train control center, a dispatch center, or the like. As shown in FIG. 1, the control method of the locomotive wireless communication device comprises a step S100 and a step S300.
S100, if the locomotive wireless communication equipment is at least in a call state with two ground equipment at the same time and the network system adopted by each ground equipment is different, acquiring a voice signal set.
The set of voice signals includes voice signals transmitted by ground devices in a talk state with the locomotive wireless communication device. The staff of train control center, dispatch center etc. can transmit railway system information, dispatch information, control information etc. to locomotive wireless communication equipment through voice signal, and staff on the locomotive can learn the above information in the voice signal through locomotive wireless communication equipment.
Specifically, when the locomotive wireless communication device needs to communicate with a plurality of ground devices of different systems at the same time, for example, when the locomotive wireless communication device performs group calling, if the ground devices of different network systems transmit voice signals at the same time, the voice signals can affect each other, so that the loss phenomenon of the voice signals occurs, and the locomotive wireless communication device cannot transmit the information to be transmitted by the ground devices to locomotive staff, so that the safe and stable operation of a train is threatened. In one embodiment, a plurality of communication modules are arranged on the locomotive wireless communication device, each communication module is used for receiving voice signals transmitted by a corresponding network system, and a controller of the locomotive communication module collects and gathers the voice signals acquired by each communication module into a voice signal set.
S300, performing audio mixing processing on the voice signal set to obtain and output a mixed audio signal.
In order to solve the above problem, when the locomotive wireless communication device needs to communicate with a plurality of ground devices of different systems at the same time, the acquired voice signal set is subjected to audio mixing processing. The mixing process can integrate the voice signals of different systems into a single mixing signal, wherein the mixing signal contains the information of each voice signal in the voice signal set. Optionally, the mixed signal is output through a speaker of the locomotive wireless communication device. In addition, the locomotive wireless communication equipment can be in communication connection with the mobile terminal, the locomotive wireless communication equipment outputs the mixed sound signal to the mobile terminal, and a worker of the locomotive can play the mixed sound signal through a loudspeaker on the mobile terminal, so that the worker of the locomotive can also receive the mixed sound signal at a place far away from the locomotive wireless communication equipment. In one embodiment, an audio matrix circuit is provided on the locomotive wireless communication device for mixing the set of speech signals.
Based on the control method of the locomotive wireless communication equipment in the embodiment, voice signals of various different network systems are mixed, so that the locomotive wireless communication equipment completely receives the voice signals sent by each ground equipment, the locomotive wireless communication equipment cannot lose scheduling information, control information and the like transmitted by the ground equipment, and support is provided for safe and stable operation of the locomotive. Especially under the large background that the network systems of all sections are inconsistent, the updating of the network systems of all sections does not need to be carried out in one step, the problem of gradual updating and upgrading of all supporting facilities in the communication development process is solved, and the method has important application and maintenance values for compatible transition of communication updating and upgrading of the current domestic railway.
In one embodiment, as shown in fig. 2, step S300 is preceded by step S200 and step S210.
S200, the audio intensity of each voice signal in the voice signal set is obtained.
In particular, the audio intensity may be a decibel value of the speech signal. The voice signal is converted into an electric signal during collection and transmission, so that the audio intensity can also be the voltage amplitude of the electric signal corresponding to the voice signal or square the voltage amplitude to obtain the energy value of the electric signal corresponding to the voice signal.
S210, filtering the voice signals with the audio intensity lower than the preset intensity in the voice signal set.
It will be appreciated that each surface device, when communicating with the locomotive wireless communication device, may collect and transmit noise in the environment to the locomotive wireless communication device, which will affect the quality of the call between the surface device and the locomotive wireless communication device. According to the characteristic that the audio intensity of the noise is generally lower, the voice signals with the audio intensity lower than the preset intensity in the voice signal set are regarded as the noise, and the voice signals with the lower audio intensity are filtered, so that the conversation quality of the car-ground conversation is enhanced.
In one embodiment, the method of controlling a locomotive wireless communication device further comprises: and if the locomotive wireless communication equipment is in a call state with at least two ground equipment, modulating the voice signals to be transmitted of the locomotive wireless communication equipment, and transmitting the voice signals to be transmitted after the modulation to the corresponding ground equipment according to a network system corresponding to each ground equipment in the call state of the locomotive wireless communication equipment. It is understood that the signal to be transmitted is a voice signal transmitted by the locomotive wireless communication device to the ground equipment. When the locomotive wireless communication device transmits voice signals to the ground device of each network system, the voice signals can be transmitted only when the voice signals are required to be modulated to different frequency bands in each network system. In order to ensure that the ground equipment of each network system can effectively receive the reply of the locomotive, the frequency bands of signals to be transmitted are respectively modulated into voice signals suitable for being transmitted in each network system, and the processed signals to be transmitted are stably transmitted to the corresponding ground equipment.
In one embodiment, the ground device includes a first ground device and a second ground device, where the first ground device is in a call state with the locomotive wireless communication device, and the network system of the first ground device is different from that of the second ground device, as shown in fig. 3, and the method further includes step S500 and step S510.
S500, if the locomotive wireless communication equipment receives a call request of the second ground equipment, comparing the communication priority of the first ground equipment and the second ground equipment.
The communication priority is determined according to the network system. It can be understood that when the locomotive wireless communication device only needs a single ground device to make simultaneous calls, for example, when the locomotive wireless communication device makes a single call or a single call, if there is another network type ground device, that is, the second ground device, at this time, a call request is sent to the locomotive wireless communication device, and the embodiment determines that the locomotive wireless communication device should make a call with the first ground device or the second ground device according to the communication priority of the first ground device and the second ground device. Specifically, the ground equipment with higher network system advanced level has better call quality, and the core part of the railway system can finish the network system upgrade preferentially, so the ground equipment with higher network system advanced level has higher communication priority. In a specific embodiment, the network system includes LTE/5G-R, GSM-R and 450M, and the communication priority corresponding to each network system is sequentially from high to low: LTE/5G-R, GSM-R, 450M. It can be understood that LTE/5G-R is the latest generation network system, and has the advantages of high stability, high transmission speed and the like, and the communication priority is the highest.
S510, if the communication priority of the second ground equipment is higher than that of the first ground equipment, the locomotive wireless communication equipment exits the communication state with the first ground equipment and enters the communication state with the second ground equipment.
In one embodiment, as shown in FIG. 4, the steps of exiting the locomotive wireless communication device from a talk state with a first surface device and entering a talk state with a second surface device in step S510 include steps S511 through S515.
S511, judging the type of the call request.
Specifically, the call request includes an emergency call request and a non-emergency call request.
S513, if the type of the call request is an emergency call request, the locomotive wireless communication device exits the call state with the first ground device and enters the call state with the second ground device.
The emergency call request is related to the safety of the locomotive and the railway system, the locomotive wireless communication device is required to immediately answer, and the locomotive wireless communication device directly exits from the first ground device and starts to communicate with the second ground device.
And S515, if the type of the call request is a non-emergency call request, sending a prompt signal until the switching instruction is acquired, and the vehicle wireless communication device exits the call state with the first ground device and enters the call state with the second ground device.
Specifically, the prompt signal is used for prompting the identity of the second ground equipment of the staff on the locomotive, and the prompt signal can be sent out through a display device or a loudspeaker for broadcasting. The switching instruction is input to the locomotive wireless communication device when the current call object is to be switched from the first ground device to the second ground device, and the switching instruction can be sent by a worker on the locomotive through operating the locomotive wireless communication device. In the case of step S515, the locomotive wireless communication device will always send a prompt signal to alert that a new incoming call is present until either a handoff instruction is received or the second ground device stops sending a call request.
It should be understood that, although the steps in the flowcharts of fig. 1-4 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
