Fig. 4 shows a flowchart of a method for monitoring an obstacle in front of a train according to an embodiment of the present invention. The method steps defined by the flow related to the method are applied to the monitoring system. The specific process shown in fig. 4 will be described in detail below:
and S00, the video acquisition terminal is initially in a dormant state and intermittently sends out radio wave signals including handshake messages.
When the video acquisition terminal is in a sleep mode, the radio wave signal comprising the handshake message is sent out only through the antenna, and the camera unit and other functional modules are in a closed state, so that the energy consumption of the video acquisition terminal is saved; when the video acquisition terminal is in a working mode, the camera shooting unit and other functional modules are in an open state; therefore, each video acquisition terminal on the track is in a dormant state when the train does not approach, and energy consumption is saved.
In addition, the effective distance of the radio wave signals radiated outwards through the antenna can be controlled within a certain range (for example, set to be about 5 KM) by setting the parameters of the radio wave signals sent by the video acquisition terminal, and only when the train runs into the range, the monitoring terminal on the train can receive the radio wave signals including the handshake messages.
And S10, controlling the monitoring terminal to monitor the radio wave signals sent by the video acquisition terminals in real time.
When the train gradually moves forwards, the train gradually enters the effective range of the radio wave signals of the video acquisition terminals in front of the train moving direction, and therefore the monitoring terminal can sequentially receive the radio wave signals carrying the handshake messages sent by the video acquisition terminals in front of the train.
It can be understood that a plurality of video acquisition terminals with short spacing distance can form a local ad hoc wireless communication network, one video acquisition terminal closest to the train intermittently transmits a radio wave signal with a handshake message, and after the train receives the radio wave signal, the train can be accessed into the wireless communication network, so as to establish communication connection with all the video acquisition terminals in the wireless communication network.
And S20, after the monitoring terminal monitors the radio wave signal, establishing communication connection with a corresponding video acquisition terminal, and receiving image data acquired by the video acquisition terminal.
The monitoring terminal establishes communication connection with the corresponding video acquisition terminals according to the analysis of handshake message information in the received radio wave signals, and the monitoring terminal establishes communication connection with the corresponding video acquisition terminals according to the number of the received radio wave signals and controls the corresponding video acquisition terminals to send the acquired image data to the video acquisition terminals when the train runs to the radio wave signal strength to accommodate video data transmission.
And S30, controlling the monitoring terminal to display the image data collected by at least one video collection terminal closest to the front of the train.
In practical application, the number of the displayed video acquisition terminals can be determined according to the size of a display module of the monitoring terminal or a connected display, images acquired by four or nine video acquisition terminals closest to the front of the train are usually displayed in four or nine grids, and of course, the number of the displayed video acquisition terminals can also be determined according to actual requirements.
In one embodiment, step S20 specifically includes the following steps:
and S21, after the monitoring terminal monitors the radio wave signal, establishing communication connection with the corresponding video acquisition terminal.
S22, controlling the video acquisition terminal which establishes the connection to switch from a dormant state to a working state, and enabling the video acquisition terminal to acquire the image data of the track at the position where the video acquisition terminal is located.
That is to say, when the train runs to the monitoring terminal, the monitoring terminal can receive the radio wave signal and establish communication connection with the corresponding video acquisition terminal, the video acquisition terminal is awakened, and the video acquisition terminal is switched from the dormant state to the working state to acquire the image data. And analyzing the acquired image data, and generating alarm information and sending the alarm information to the monitoring terminal when judging that the obstacle exists on the track in the image data.
Preferably, after the video acquisition terminal enters a working state, the video acquisition terminal acquires environmental data generated by an environmental detection sensor, analyzes the environmental data, and generates alarm information and sends the alarm information to the monitoring terminal when judging that a threat event occurs at the position where the video acquisition terminal is located. The environment detection sensor comprises one or more of a pressure sensor, a vibration sensor, a GPS sensor and a temperature sensor which are arranged on the video acquisition terminal.
The pressure sensor is arranged in a closed space inside the video acquisition terminal, detects a pressure value in the closed space in real time, and generates alarm information when the pressure value is lower than a set value.
The method comprises the steps that vibration information of the ground around the position where a video acquisition terminal is located can be detected through a vibration sensor, whether threat events (such as debris flow, falling rocks, mountain collapse and the like) occur around the video acquisition terminal is judged according to the vibration information, and if yes, alarm information is generated and sent to a monitoring terminal; for example, when debris flow occurs near the position of the video acquisition terminal but the debris flow does not spread to the shooting range of the video acquisition terminal, the image recognition alarm module cannot be triggered to alarm at the moment, but the vibration sensor can detect abnormal vibration information and generate corresponding alarm information to send the alarm information to the monitoring terminal, so that whether threat conditions exist in a track area in front of a train or not can be predicted to a certain extent, and the safety of the train in the running process is further ensured.
The three-dimensional position information of the video acquisition terminal can be identified through the GPS sensor, so that whether displacement caused by artificial generation or natural factors (such as debris flow, rockfall, mountain collapse and the like) exists or not is judged according to the change of the three-dimensional position information, and if yes, corresponding alarm information is generated.
The ambient temperature of the position where the video acquisition terminal is located can be obtained through the temperature sensor, and when the ambient temperature is lower than a preset temperature (for example, an extreme low temperature), a preset heater in the video acquisition terminal can be started, so that the video acquisition terminal can work normally.
And S23, when the train runs to the state that the signal intensity of the radio wave signal is larger than a preset signal threshold value, controlling the video acquisition terminal to send the image data to the monitoring terminal.
When the signal intensity of the radio wave signals is larger than a preset signal threshold value, the distance between the monitoring terminal and the video acquisition terminal is about 3KM approximately, the video data transmission can be stably carried out, and the monitoring terminal can receive the image data sent by the video acquisition terminal and select whether to display according to the number of the display pictures.
In another embodiment, the step S30 specifically includes the following steps:
and S31, detecting the distance between the monitoring terminal and each video acquisition terminal which has established communication connection.
After the monitoring terminal establishes communication connection with the corresponding video acquisition terminal according to the received radio wave signals, distance measurement can be carried out according to the radio wave signals between the monitoring terminal and the corresponding video acquisition terminal, so that the distance between the monitoring terminal and each video acquisition terminal which establishes communication connection can be known.
And S32, controlling the monitoring terminal to select the image data collected by at least one video collection terminal with the closest distance from the video collection terminals with the established communication connection for display.
Therefore, a train driver can visually check the track condition in front of the train, can know whether barriers exist at each position of the track in front of the train in advance, and ensures the safety of track traffic during operation. In addition, a video acquisition terminal can be arranged at the intersection where the track and the road intersect, and the video acquisition terminal acquires image data on the road, so that a train driver can observe whether vehicles are preparing to pass through the intersection on the road in advance, and the train driver can judge whether the speed needs to be reduced in advance, and the occurrence of collision between the train and the vehicles is avoided.
In yet another embodiment, the method of an embodiment of the present invention further comprises the steps of:
and S40, controlling the video acquisition terminal to be switched from a working mode to a sleep mode according to the fact that the distance between the monitoring terminal and one of the video acquisition terminals is larger and exceeds a preset distance.
When the distance between the monitoring terminal and a certain video acquisition terminal is measured to be larger and larger through the radio wave signal, the positions of the monitoring terminal of the train and the video acquisition terminal are shown; the preset distance can be determined according to the length of the train where the monitoring terminal is located, namely, after the train completely passes through the position of the video acquisition terminal, the video acquisition terminal is controlled to enter a dormant state to wait for being matched with the next train, so that the power consumption of the video acquisition terminal is reduced, and the energy is saved.
