Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
The embodiment of the invention provides a control method of locomotive wireless communication equipment, wherein the locomotive wireless communication equipment is used for communicating with ground equipment by adopting different network systems, specifically, when a locomotive passes through different sections in the operation process, the improvement progress of the network systems of the sections is inconsistent, part of the sections adopt advanced LTE-R/5G network systems, but part of the sections possibly use analog network systems. The locomotive wireless communication equipment aimed at by the embodiment can support communication with the ground equipment of the network system common in the current railway system. The ground equipment may be ground equipment disposed at a train control center, a dispatch center, or the like. As shown in fig. 1, the method for controlling a locomotive wireless communication device includes steps S100 and S300.
S100, if the locomotive wireless communication equipment and at least two ground equipment are in a communication state simultaneously and the network systems adopted by each ground equipment are different, acquiring a voice signal set.
The set of voice signals includes voice signals transmitted by various ground devices in a call with the locomotive wireless communication device. Staff of the train control center, the dispatching center and the like can transmit railway system information, dispatching information, control information and the like to the locomotive wireless communication equipment through voice signals, and staff on the locomotive can obtain the information in the voice signals through the locomotive wireless communication equipment.
Specifically, when the locomotive wireless communication device needs to communicate with multiple 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 may affect each other, and thus the voice signals are lost, the locomotive wireless communication device cannot transmit information that the ground devices need to transmit to locomotive workers, so that the safe and stable operation of the train is threatened. In one embodiment, a plurality of communication modules are arranged on the locomotive wireless communication equipment, each communication module is used for receiving voice signals transmitted by a corresponding network system, and a controller of each locomotive communication module collects and assembles the voice signals acquired by each communication module into a voice signal set.
And S300, performing sound mixing processing on the voice signal set to obtain and output a sound mixing signal.
In order to solve the above problem, when the wireless communication device of the locomotive 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 audio mixing process can integrate the audio signals of different systems into a single audio mixing signal, and the audio mixing signal contains the information of each audio signal in the audio signal set. Optionally, the mixed sound 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 audio mixing signal to the mobile terminal, and a worker of the locomotive can play the audio mixing signal through a loudspeaker on the mobile terminal, so that the worker of the locomotive can receive the audio mixing signal at a place far away from the locomotive wireless communication equipment. In one embodiment, the locomotive wireless communication device is provided with an audio matrix circuit, and the audio matrix circuit is used for carrying out sound mixing processing on the voice signal set.
Based on the control method of the locomotive wireless communication equipment in the embodiment, voice signals of different network systems are mixed, 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 safety, stability and operation of the locomotive. Particularly, under the large background that the network systems of all sections are not consistent, the network systems of all sections do not need to be updated in one step, the problem that all supporting facilities are gradually upgraded and updated in the communication development process is solved, and the method has important application and maintenance values for the communication upgrading, updating and compatible transition of the current domestic railway.
In one embodiment, as shown in fig. 2, step S300 further includes step S200 and step S210.
S200, obtaining the audio intensity of each voice signal in the voice signal set.
Specifically, 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 the voltage amplitude is subjected to square operation to obtain the energy value of the electric signal corresponding to the voice signal.
S210, filtering the voice signals of which the audio intensity is lower than the preset intensity in the voice signal set.
It can be understood that each ground device may collect and transmit noise in the environment to the locomotive wireless communication device when communicating with the locomotive wireless communication device, and the noise will affect the communication quality between the ground device and the locomotive wireless communication device. According to the characteristic that the audio intensity of the noise is generally low, 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 low audio intensity are filtered, so that the communication quality of the vehicle-ground communication is enhanced.
In one embodiment, the method of controlling a locomotive wireless communication device further comprises: if the locomotive wireless communication equipment and at least two pieces of ground equipment are in a communication state at the same time, modulating the voice signal to be transmitted of the locomotive wireless communication equipment, and transmitting the voice signal to be transmitted after modulation to the corresponding ground equipment according to the network system corresponding to each piece of ground equipment in the communication state of the locomotive wireless communication equipment. It can be understood that the signal to be transmitted is a voice signal transmitted from the locomotive wireless communication device to the ground equipment. When the locomotive wireless communication equipment transmits voice signals to ground equipment of each network type, the voice signals can be transmitted only when being modulated to different frequency bands in each network type. In order to ensure that the ground equipment of each network system can effectively receive the reply of the locomotive, the frequency bands of the signals to be transmitted are respectively modulated into voice signals suitable for being transmitted in each network system, and then the processed signals to be transmitted are stably transmitted to the corresponding ground equipment.
In one embodiment, the ground devices include a first ground device and a second ground device, the first ground device is in a communication state with the locomotive wireless communication device, and the network systems of the first ground device and the second ground device are different, as shown in fig. 3, the method further includes step S500 and step S510.
And S500, if the locomotive wireless communication equipment receives the call request of the second ground equipment, comparing the communication priority of the first ground equipment with that of the second ground equipment.
The communication priority is determined according to the network type. It can be understood that, when the locomotive wireless communication device only needs a single ground device to communicate simultaneously, for example, when the locomotive wireless communication device makes a single call or a single call, if there is another ground device of another network system, that is, the second ground device, to send a communication request to the locomotive wireless communication device, this embodiment determines that a communication with the first ground device or the second ground device should be performed next according to the communication priorities of the first ground device and the second ground device. Specifically, the ground devices with higher degree of network system advancement have better speech quality and the core part of the railway system will preferentially complete the upgrade of the network system, so the ground devices with higher degree of network system advancement have higher communication priority. In a specific embodiment, the network types include LTE/5G-R, GSM-R and 450M, and the communication priorities corresponding to the network types are, in order from high to low: LTE/5G-R, GSM-R, 450M. It can be understood that the LTE/5G-R is the latest generation network system, has the advantages of high stability, high transmission speed and the like, and has the highest communication priority.
And 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 step of the locomotive wireless communication device exiting the communication state with the first ground device and entering the communication state with the second ground device in step S510 includes steps S511 to S515.
S511, judging the type of the call request.
Specifically, the call requests include emergency call requests and non-emergency call requests.
S513, if the type of the call request is the 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 information of the locomotive and the railway system, and the locomotive wireless communication equipment is required to immediately respond, and the locomotive wireless communication equipment directly exits from the first ground equipment and starts to communicate with the second ground equipment.
And S515, if the type of the call request is a non-emergency call request, sending a prompt signal until the switching instruction is obtained, and the wireless communication device of the locomotive exits the call state with the first ground device and enters the call state with the second ground device.
Particularly, 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 in a display device display or loudspeaker broadcasting mode. The switching instruction is input to the locomotive wireless communication device when the current call object is confirmed to be switched from the first ground device to the second ground device, and the switching instruction can be sent by an operator on the locomotive through operating the locomotive wireless communication device. In the case of step S515, the locomotive wireless communication device will always send out the prompting signal to prompt a new incoming call until receiving the switching command or the second ground device stops sending out the call request.
It should be understood that although the various steps in the flowcharts of fig. 1-4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-4 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps or stages.
