Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Before introducing the method, the apparatus, and the storage medium for early warning of vehicle location provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The vehicle in the application scenario may be any vehicle that runs according to a preset track, for example: the signal system used in the running process of the vehicle is an ATS (Automatic Train monitoring) system, and the ATS system may include: modules such as a dispatcher workstation (dual redundancy), an operation diagram workstation, a server (dual redundancy), a local control workstation (dual redundancy), and the like, wherein the server of the ATS system may include: an application server, a database server, a control unit server, etc., and the server in this embodiment may be an application server. The operation terminal in the application scenario may be, for example, a mobile terminal such as a smart phone, a tablet computer, a smart watch, and a PDA (Personal Digital Assistant).

Fig. 1 is a flowchart illustrating a method for warning a vehicle location according to an exemplary embodiment, where the method is applied to a server of an ATS system, as shown in fig. 1, and includes the steps of:

step 101, receiving job information sent by a job terminal, wherein the job information comprises an identification code and a job position of the job terminal.

For example, when the operator performs the work on the work track, the current work position may be set by the work terminal. For example, after the operator arrives at the destination, the current work position may be manually input through a control interface of the work terminal, the current work position may be acquired by a wireless signal (e.g., a satellite positioning signal, a movement data signal, etc.) on the work terminal, or the current work position may be obtained by integrating the work position manually input by the operator and the work position determined by the wireless signal. And then, the operation terminal sends operation information containing an identification code of the operation terminal and an operation position to a server of the ATS system, wherein the identification code of the operation terminal can uniquely identify the operation terminal, and when a plurality of operators use the operation terminals on the track at the same time, the operation information sent by one of the operation terminals can be determined according to the identification code.

Further, the operator can carry the operation terminal with him or her, and can place the operation terminal at a designated position. For example, when the worker needs to move continuously during the process of the job, the worker can input the current job position when starting the job and carry the job terminal with the worker, and during the process of moving the job terminal, the job position can be updated in real time according to the wireless signal, and the job information containing the updated job position is sent to the server according to the preset time frequency (for example, 5 minutes), so that the server can acquire the job position of the job terminal in real time.

And 102, determining at least one target vehicle according to the operation position.

And 103, acquiring the running position of the target vehicle, and if the distance difference between the running position and the operation position is smaller than or equal to an early warning threshold value, sending early warning information to the operation terminal according to the identification code so as to enable the operation terminal to carry out early warning.

For example, after receiving the job information, the server may parse the job information according to a preset rule or protocol to obtain the job location and the identification code. One or more target vehicles that may be threatening the operator are then determined based on the work location. For example, the server may search for a target vehicle through a dispatcher workstation or a map workstation in the ATS system, for example, all vehicles currently traveling online are taken as the target vehicle, a vehicle belonging to the same route as the operation position among all vehicles currently traveling online may be selected as the target vehicle according to the operation position, and a vehicle within a certain range (for example, within 200 km) from the operation position among all vehicles currently traveling online may be selected as the target vehicle according to the operation position. And then determining the current driving position of the target vehicle through a dispatcher workstation or a running chart workstation in the ATS system. Compared with the prior art that the GNSS positioning device is installed on the vehicle to determine the running position of the vehicle, the running position in the embodiment of the disclosure is determined by the ATS system arranged on the vehicle, no additional hardware equipment is needed to be added, the interference of the external environment is avoided, and the accuracy and the safety degree are extremely high.

Further, after the driving position is determined, whether the warning information needs to be sent to the operation terminal is determined according to a distance difference between the driving position and the operation position, wherein the warning information may further include the distance difference. The server can obtain the driving position of the target vehicle in real time according to a preset time interval (for example, 2s), so that the distance difference between the driving position and the operation position is updated in real time, an early warning threshold (for example, 500m) can be preset, when the distance difference is smaller than or equal to the early warning threshold, the server sends early warning information to the operation terminal, and the operation terminal performs early warning after receiving the early warning information to prompt an operator to notice avoidance. When the distance difference is larger than the early warning threshold value, the server can continue to acquire the driving position of the target vehicle.

For example, the operator sets the current job position to 0503 logical field through the job terminal whose id is 0x 02. The format of the job information sent by the job terminal to the server may be 0x 010 x 020 x 050 x03, where 0x01 indicates that the data is job information (it can be understood that the data is used to set a job location), 0x02 indicates that the data is sent by the job terminal identified by 0x02, and 0x 050 x03 indicates that the corresponding job location is 0503 logical zone. The server searches for a position corresponding to the 0503 logic segment in the ATS system as 5500m (namely, an operation position), and determines that a driving position of a target vehicle corresponding to the 0503 logic segment is at a position shifted by 50m in the 0102 logic segment, wherein the position corresponding to the 0102 logic segment is 1000m, the driving position of the target vehicle is 1000+50 ═ 1050m, then a distance difference between the driving position and the operation position is |1050 | _ 5500| -4450 m, and if the early warning threshold is 500m, then early warning is not needed. After the target vehicle travels to a position deviated by 100m in a 0501 logical segment after a period of time, the position corresponding to the 0501 logical segment is 4950m, the travel position is 5050m, the distance difference is |5050 | _ 5500| _ 450m and is smaller than an early warning threshold value, the server sends early warning information to the operation terminal, and the format of the early warning information can be 0x 020 x 020 x 010 xC2, wherein the first 0x02 represents that the data is the early warning information, the second 0x02 represents that the early warning information is sent to the operation terminal identified by 0x02, and 0x 010 xC2 represents that the distance difference between the target vehicle and the operation terminal is 450 m.

In summary, in the present disclosure, the job terminal transmits job information including the identification code and the job location to the server of the ATS system. The server determines one or more target vehicles according to the operation positions and acquires the running positions of the target vehicles. And then when the distance difference between the driving position and the operation position is smaller than or equal to the early warning threshold value, the server sends early warning information to the operation terminal according to the identification code so as to enable the operation terminal to carry out early warning. The position of the operation terminal and the position of the vehicle are obtained based on the ATS system, so that early warning is performed when the vehicle is close to the operation terminal, a positioning device does not need to be additionally arranged, interference of an external environment is avoided, and stable and accurate early warning can be provided for the operation terminal.

Fig. 2 is a flowchart illustrating another method for warning a vehicle location according to an exemplary embodiment, and as shown in fig. 2, the step 102 may be implemented by:

step 1021, determining the target line to which the operation terminal belongs according to the operation position.

And step 1022, taking all vehicles running on the target route at the current moment as target vehicles.

In a specific application scenario, a target vehicle that may threaten an operator should belong to the same route as the operation location, for example, in the same station, which may include: the LT line, the JH line and the FT line, on which the operator needs to work, may be in a format of 0x 010 x 020 x4C 0x 540 x 050 x03, where 0x4C 0x54 represents the LT line, and the work location is the LT0503 logical zone. Correspondingly, the server determines the LT line as the target line according to LT0503, and then takes all vehicles currently running online on the LT line as the target vehicles.

In one usage scenario, the target vehicle may be multiple, and then step 103 may be:

first, a travel position of each of a plurality of target vehicles is acquired.

Thereafter, a difference in distance between each travel position and the work position is determined.

And finally, if the minimum distance difference is smaller than or equal to the early warning threshold value, sending early warning information to the operation terminal according to the identification code.

For example, there may be a plurality of target vehicles, then in step 103, the server may obtain a driving position of each of the plurality of target vehicles through a dispatcher workstation or a working diagram workstation in the ATS system, determine a distance difference between the driving position and a working position of each of the plurality of target vehicles, that is, obtain a plurality of distance differences, compare the minimum distance difference with an early warning threshold, and if the minimum distance difference is less than or equal to the early warning threshold, send early warning information to the working terminal identified by the identification code. Taking 2 target vehicles a and b as examples, the running position of a is 50m offset in an LT0202 logic section, the running position of b is 100m offset in an LT0501 logic section, the ATS system determines that the position corresponding to the LT0202 logic section is 1950m, then the running position of a is 2000m, the position corresponding to the LT0501 logic section is 4950m, then the running position of b is 5050m, respectively determines that the distance difference corresponding to a is |2000 | -5500| -3500 m, the distance difference corresponding to b is |5050 | -5500| -450 m, then the distance difference corresponding to b is the smallest, and the distance difference is smaller than an early warning threshold value, and then early warning information is sent to the operation terminal.

In order to improve the security of communication between the operation terminal and the server and protect the ATS system from interference of external signals or attack of a malicious third party, a VPN (Virtual Private Network) channel may be pre-established, and then the implementation manner of step 101 may be:

and receiving the operation information sent by the operation terminal through a preset VPN channel.

The implementation of step 103 may be:

and sending early warning information to the operation terminal through the VPN channel according to the identification code.

Specifically, the establishing of the VPN channel may be by presetting a VPN Server (for example, a Windows Server 2012 system may be adopted), and the VPN Server is connected to the public network and the ATS system through an Ethernet (english: Ethernet). The operation terminal is connected with a public network through a wireless network, and the wireless network can be: 3G (English: 3rd-Generation, Chinese: third-Generation mobile communication technology), 4G (English: 4th-Generation, Chinese: fourth-Generation mobile communication technology), WLAN (English: Wireless Local Area Networks, Chinese: Wireless Local Area Networks), etc. Each operation terminal accesses a VPN server through a public network, and registers with an account provided by the VPN server, and the VPN server allocates a designated IP (Internet Protocol) address to each operation terminal. The server only receives the operation information sent by the appointed IP address through the VPN channel, and correspondingly, the server only sends the early warning information to the appointed IP address through the VPN channel, so that the transmission safety of the operation information and the early warning information is ensured, and the interference or attack of external data to the ATS system is blocked.

It should be noted that, after receiving the job information, the server may further send the job information to a dispatcher workstation of the ATS system, and display the job position on a site map of the dispatcher workstation for the dispatcher to view, so that the dispatcher can dispatch the vehicle with reference to the job position.

Fig. 3 is a flowchart illustrating a method for warning a vehicle position according to an exemplary embodiment, where the method is applied to a work terminal, as shown in fig. 3, and includes the following steps:

step 201, sending operation information to a server of the ATS system, wherein the operation information comprises an identification code of an operation terminal and an operation position, so that the server determines at least one target vehicle according to the operation position and acquires a running position of the target vehicle.

Step 202, receiving early warning information, wherein the early warning information is information sent to the operation terminal according to the identification code when the distance difference between the traveling position and the operation position of the server is smaller than or equal to an early warning threshold value.

And step 203, early warning is carried out according to the early warning information.

Specifically, the specific implementation manner in step 201 and step 202 has already been described in the above embodiments, and is not described here again. In step 203, after receiving the warning information, the operation terminal may perform warning in different manners. For example, the warning information may be sent to the operation terminal in a form of a short message, and displayed on a display interface of the operation terminal, and the operation terminal may vibrate to prompt an operator. Furthermore, the operation terminal can be further provided with a sound player and an indicator light, after the early warning information is received, the sound player can play the early warning information or play a designated early warning sound (such as an alarm bell, a buzzer and the like), and the indicator light can start to flash.

Fig. 4 is a flowchart illustrating another method for warning a vehicle location according to an exemplary embodiment, where the warning information includes a distance difference, as shown in fig. 4, and step 203 can be implemented by:

step 2031, determining target parameters according to the distance difference, wherein the target parameters include sound parameters and/or display parameters.

And 2032, playing the early warning information according to the sound parameters, and/or displaying the early warning information according to the display parameters.

Specifically, if the warning information includes the distance difference, the smaller the distance difference is, the closer the vehicle is to the operation terminal, the more urgent the situation is, the greater the threat to the operator is, and therefore the operation terminal can perform warning in different ways according to the difference in distance. For example, the sound parameter and the display parameter of the early warning can be determined according to the distance difference, and then the early warning can be performed according to the sound parameter and the display parameter. The sound parameters may include: volume, frequency of sound, etc., the display parameters may include: flicker frequency, display brightness, etc. For example, the smaller the distance difference is, the greater the volume of the warning message played by the work terminal, or the greater the frequency of the sound of the warning sound. The smaller the distance difference is, the higher the display brightness of the display interface of the operation terminal in displaying the early warning information is, or the higher the flashing frequency of the indicator lamp of the operation terminal is.

Similarly, in order to improve the security of communication between the operation terminal and the server and protect the ATS system from being interfered by external signals or being attacked by a malicious third party, a VPN tunnel may be pre-established, and then the implementation manner of step 201 may be:

and sending the operation information to the server through a preset VPN channel.

The implementation of step 202 may be:

and receiving the early warning information through the VPN channel.

For example, a VPN server may be preset to establish a VPN tunnel, and the job terminal is connected to a public network through a wireless network, where the wireless network may be: 3G, 4G, WLAN, etc., the VPN server is respectively connected with the public network and the ATS system through the Ethernet. Each job terminal accesses a VPN server via a public network, registers with an account provided by the VPN server, and the VPN server assigns a designated IP address to each job terminal. The operation terminal accesses the VPN server through the appointed IP address and sends the operation information to the server, and correspondingly, the operation terminal receives the early warning information sent by the VPN server through the appointed IP address. Therefore, the safety of transmission of the operation information and the early warning information is ensured, and the interference or attack of external data to the ATS system is blocked.

It should be noted that the operating system of the operation terminal may be an Android system or an iOS system, and an Application program (APP for short) capable of executing the above embodiment may be installed on the operating system, and the Application program may be developed based on HMI (Human Machine Interface, chinese: Human Machine Interface) software used by a station diagram in the ATS system, so as to be convenient for an operator to use and reduce corresponding development workload.

Further, after the worker completes the previous job, a cancel instruction may be input through the control interface of the job terminal, and the job terminal sends the cancel instruction to the server, where the format of the cancel instruction may be, for example, 0x 030 x 020 x 050 x03, where 0x03 indicates that the data is a cancel instruction (it may be understood that the data is used to indicate a cancel warning), 0x02 indicates that the data is sent by the job terminal identified by 0x02, and 0x 050 x03 indicates that the corresponding job location is a 0503 logical segment. After receiving the cancel instruction, the server does not give an early warning to the work terminal identified by 0x02, that is, does not acquire the distance difference between the travel position and the work position.
