Detailed Description of the Embodiment

[0049] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0050] Terms such as "first", "second", etc. in the specification and claims of the present application and the above - mentioned drawings are used to distinguish similar objects, and do not have to be understood as a specific order or sequence. Additionally, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0051] In the description of the present disclosure, unless otherwise specified, "and / or" is an association relationship describing associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Here, A and B can be singular or plural.

[0052] Before introducing the specific embodiments of the present disclosure in detail, the application scenarios of the present disclosure will be described first. The present disclosure can be applied to the passenger alarm scenario in rail transit trains. With the rapid development of rail transit in various countries around the world, due to its uniqueness, large transportation capacity, speed, economy, safety and other factors, rail transit has become the preferred mode of travel for people in modern cities. Since the number of passengers carried by each train is huge, the number of unexpected situations in the carriages has increased sharply. In order to save the lives of passengers and reduce property losses in case of emergencies, in the prior art, a rail transit vehicle-mounted broadcast control box is provided on the train, which is mainly used for driver manual broadcasting, driver-passenger alarm intercom and driver-driver intercom at both ends.

[0053] The existing on-vehicle passenger emergency alarm method usually consists of a button, a speaker, a microphone, an indicator light, a sound processing unit and a metal shell. In case of an emergency, when a passenger chooses to alarm, the alarm device emits an alarm sound after the alarm button is pressed. At this time, the passenger can only wait for the driver or security personnel to come and check the situation.

[0054] However, with the above solution, when a passenger alarms, the driver cannot view the actual situation in the passenger carriage at that time, so he cannot judge the urgency and cannot choose the correct treatment method. For example, whether to immediately take an emergency stop, notify the vehicle dispatching group, and urgently organize the evacuation of passengers, or continue to operate to the next station and hand it over to the staff on the next platform for handling, resulting in the driver being unable to accurately judge the urgency of the passenger and take the correct emergency treatment measures.

[0055] In order to overcome the technical problems existing in the above related technologies, the present disclosure provides a communication system and a train. The communication system includes: a controller; a display connected to the controller; an alarm connected to the controller for collecting first image information of the location of the alarmed passenger; a photographing device connected to the controller for collecting second image information of the location of the driver; the controller is configured to, when the alarm is triggered, control the alarm to transmit the first image information to the display, and control the photographing device to transmit the second image information to the alarm; the display is configured to display the first image information. In this way, when the alarm is triggered, according to the photographing device included in the communication system, a real-time picture of the location where the alarmed passenger is located can be provided in real time, enabling the driver to timely obtain the real-time image picture of the location where the passenger alarms, judge the urgency of the passenger, so that the driver can take the correct corresponding treatment measures and avoid the loss of life and property due to untimely relief of the passenger.

[0056] The following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0057] Figure 1 is a structural block diagram of a communication system 100 shown according to an exemplary embodiment, asFigure 1 As shown, the communication system 100 can be applied to a train. The communication system 100 includes: a controller 101, a display 102, an alarm 103, and a photographing device 104. The display 102, the alarm 103, and the photographing device 104 are all connected to the controller 101.

[0058] Among them, the alarm 103 is used to collect first image information of the location of the alarmed passenger; the photographing device 104 is used to collect second image information of the location of the driver; the controller 101 is used to control the alarm 103 to transmit the first image information to the display 102 when the alarm 103 is triggered, and control the photographing device 104 to transmit the second image information to the alarm 103, and the display 102 is used to display the first image information.

[0059] Among them, the communication system 100 can be applied to a rail transit train. Considering that the space of the rail transit train is too large, the number of passengers carried by the train is huge, and the number of accidents in the carriage has increased sharply, the alarm 103 can be arranged inside the carriage.

[0060] In this solution, when an accident occurs in the carriage and a passenger makes an emergency alarm, the alarm 103 can be triggered. The alarm 103 sends an alarm signal triggered by the alarmed passenger to the connected controller 101; the alarm 103 can also be provided with a camera. When the alarm 103 is triggered by the alarmed passenger, the camera of the alarm 103 is controlled to be turned on to collect first image information of the location of the alarmed passenger; when the controller 101 receives the alarm signal, it can determine that the alarm 103 is triggered, control the alarm 103 to transmit the first image information to the display 102, and the controller 101 can also control the photographing device 104 to transmit the collected second image information to the alarm 103; and the first image information is displayed through the display 102; to realize the two-way video function between the passenger and the driver when the alarmed passenger makes an alarm.

[0061] Exemplarily, an alarm button can be arranged on the alarm 103. When a passenger has an emergency, the alarm 103 can be triggered by pressing the alarm button.

[0062] By adopting the above technical solution, when the alarm 103 is triggered, according to the photographing device 104 included in the communication system 100, a real-time picture of the location where the alarmed passenger is located can be provided in real time, enabling the driver to timely obtain a real-time image picture of the location where the passenger makes an alarm, judge the emergency level of the passenger, so that the driver can take correct corresponding treatment measures to avoid the loss of life and property caused by the untimely relief of the passenger.

[0063] In some embodiments, such as Figure 2 shown, the communication system 100 may further include an intercom device 105.

[0064] Among them, the intercom device 105 is connected to the controller 101, and can be used to collect first audio information, and can also be used to play second audio information collected by the alarm 103.

[0065] The first audio information may include audio collected at the location where the driver is located, and the second audio information may include audio collected at the location where the alarmed passenger is located.

[0066] Optionally, the controller 101 is further configured to control the transmission of the first audio information and the second audio information between the intercom device 105 and the alarm 103.

[0067] Thus, visual intercom between the driver's cab and the passenger compartment can be realized, enabling the personnel at both operating ends to timely understand all the situations of each other, achieving real-time monitoring, improving the efficiency of problem-solving, facilitating the improvement of the passenger emergency alarm system of trains, etc., providing reliable protection for the life and property safety of passengers, and enabling the interaction synchronization of both operating ends, integrating alarm and monitoring, and further improving the passenger emergency alarm system.

[0068] Specifically, in a specific embodiment, the image information may be in the form of a video stream, the video stream may be in the H.264 format, the audio information may be in the form of an audio stream, the audio stream may be in the AAC format, and the two types of original data need to be encoded simultaneously and transmitted through Ethernet, and decoding is performed at the other end. There should not be excessive delay during the whole process. The devices at both the driver's cab and the carriage terminals simultaneously collect the original audio and video data. Since there is more video stream data, it is necessary to distinguish between the two different formats of data, and secondly, it is necessary to synchronize the audio and video.

[0069] In a possible implementation manner, the intercom device 105 includes an intercom processor, a speaker, and a microphone. The speaker and the microphone are respectively connected to the intercom processor, and the intercom processor is connected to the controller 101.

[0070] Among them, the speaker is used to play the second audio information; the microphone is used to collect the first audio information.

[0071] Specifically, noise reduction components are provided inside both the speaker and the microphone.

[0072] In this way, self-excitation caused by audio output feedback and resulting in howling can be avoided, and at the same time, noise can be reduced to improve the communication quality.

[0073] In some embodiments, such asFigure 3 As shown, the display interface of the display 102 displays a dial button, and the communication system 100 further includes an operation control center 106.

[0074] Among them, the operation control center 106 can be connected to the display 102 through the controller 101, and is used to collect third image information at the location where the operation control center 106 is located. The controller 101 is further used to, when the dial button is triggered, control the operation control center 106 to transmit the third image information to the display 102, and the display 102 is further used to display the third image information.

[0075] Among them, the third image information can be used to represent the image at the location of the user in the operation control center 106.

[0076] Exemplarily, a dial button is displayed on the display interface of the display 102 at the driver end. When the driver makes an emergency call, the driver triggers the dial button on the display screen, which will trigger the photographing device 104, and send the emergency call information to the operation control center 106 (OCC). The second image information obtained by the photographing device 104 can be sent to the operation control center 106, and after the OCC answers, the OCC can transmit the third image information to the display 102 through the controller 101, so that the display 102 displays the third image information. In this way, two-way video can be realized. The driver tells the operation control center 106 the passenger alarm information, and the operation control center 106 can also understand the real situation of the passenger alarm in real time and handle the passenger alarm in a timely and accurate manner.

[0077] In some embodiments, the operation control center 106 can also be connected to the intercom device through the controller 101, and is further used to collect third audio information at the location where the operation control center 106 is located; the controller 101 is further used to, when the dial button is triggered, control the transmission of the second audio information and the third audio information between the operation control center 106 and the intercom device 105.

[0078] In this way, after the operation control center 106 answers the alarm dial from the driver end, two-way video calls can be made. The driver tells the operation control center 106 the passenger alarm information, and the operation control center 106 can also understand the real situation of the passenger alarm in real time and handle the passenger alarm in a timely and accurate manner.

[0079] In a possible implementation manner, at the same time, the driver can also realize the IP phone function through the dial button on the display screen and have a visual intercom with a remote intercom device connected to the network, such as platform staff, line staff, etc., to obtain technical support and guide the driver to perform corresponding operations.

[0080] In some embodiments, the alarm 103 includes a positioning device, and the positioning device is connected to the controller 101.

[0081] The positioning device is used to obtain the position information of the alarm 103; the controller 101 is further configured to, when detecting that the alarm 103 is triggered, send the position information obtained by the positioning device to the display 102; the display 102 is further configured to display the position information of the alarm 103.

[0082] Optionally, the positioning device may be connected to a base station. When the base station receives the radio frequency signal sent by the positioning device, the preset range is the road range where the base station is located. The base station calculates the distance value from the positioning device according to the transmission time of the radio frequency signal and sends the distance value to the alarm 103. The alarm 103 obtains the position coordinates of the base station that sends the distance value, knows the location of the base station, and since the road range is certain, based on the distance value between the base station and the positioning device, the position of the positioning device can be known, and position information is generated.

[0083] By adopting the above technical solution, while obtaining the real-time image of the location where the passenger alarms, the specific location where the passenger has an emergency can be accurately judged.

[0084] In some embodiments, as Figure 4 shown, the communication system 100 further includes a storage device 107.

[0085] Among them, the storage device 107 is connected to the controller 101 and is used to store the first image information collected by the alarm 103 and the second image information collected by the photographing device 104.

[0086] Optionally, the communication system 100 further includes a power supply device, which is connected to the controller 101 and is used to supply power to the communication system 100.

[0087] By adopting the above technical solution, the audio data and video data when the passenger alarms can be precisely fused and stored, and the video recording can be provided afterwards for alarm information analysis and evidence collection.

[0088] In some embodiments, the communication system 100 includes a control box, and the control box is provided with a first space, a second space, and a partition.

[0089] Among them, the photographing device 104 and the display 102 are arranged in the first space; the controller 101 is arranged in the second space.

[0090] Exemplarily, as Figure 5 shown, Figure 5 is an exploded schematic view of the structure of a control box including a communication system shown according to an exemplary embodiment.

[0091] Exemplarily, the front housing 111 in the housing of the control box and the partition 112 form the first space 104, and the rear housing 113 in the housing of the control box and the partition 112 form the second space; the photographing device 104 and the display 102 in the communication system 100 can be installed and fixed in the first space of the control box. Wherein, a speaker 121, an emergency button board 122, a keypad 123, a pickup 124 and a headphone socket 125 can be fixed on the housing of the control box, and the speaker 121, the emergency button board 122, the keypad 123, the pickup 124 and the headphone socket 125 are electrically connected through a wire harness respectively. And the controller 101, the power supply device 108, the storage device 107 and the IO interface module 109 can be fastened to the mounting seat on the back of the partition 112 by screws; and, an electrical connector mounting hole is provided on one side of the control box for electrical connection with an external device.
