Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
Before introducing the method and the device for managing the vehicle-mounted log shown in the disclosure, an application scenario related to an embodiment of the disclosure is first described. The vehicle in the application scenario may be any vehicle running according to a preset track, for example: in the prior art, a vehicle-mounted log management device generally only records a log of a software layer, and when a voltage signal of a signal system fluctuates, the amplitude of the fluctuation of the voltage signal and the position range of the fluctuation cannot be known and recorded.
FIG. 1 is a flowchart illustrating a method of managing vehicle logs, as shown in FIG. 1, according to an exemplary embodiment, the method comprising:
step 101, acquiring a vehicle-mounted log of a signal system of a vehicle, wherein the vehicle-mounted log comprises a voltage signal and a software log.
For example, the execution subject of the present disclosure may be a vehicle-mounted log management device, which may include an acquisition module, a signal transmission module, a storage module and a CPU (english: central Processing Unit, chinese: central processing unit) module, where the acquisition module may be used for receiving a vehicle-mounted log of a signal system, the signal transmission module may be used for receiving or transmitting a vehicle-mounted log transmitted by the signal system, the storage module is used for storing the acquired vehicle-mounted log, and the CPU module is used for processing the vehicle-mounted log and controlling the receiving and transmitting of the vehicle-mounted log. The vehicle log may include a voltage signal and a software log, and the signal system may be understood as a control system for controlling the vehicle. The voltage signal of the signal system can be used for indicating the voltage provided by the vehicle to the power module of the signal system and the voltage provided by the power module to other modules except the power module in the signal system, and the software log is generated by the signal system at the software level.
Step 102, determining a signal transmission mode corresponding to the target device according to the received signal acquisition request message sent by the target device.
And step 103, sending the obtained vehicle-mounted log to the target equipment according to a signal transmission mode.
For example, in the prior art, the on-board log can only be downloaded from the on-board log management device through the on-board wireless network at the ground control center. In the method, the vehicle-mounted log can be downloaded from the vehicle-mounted log management equipment by a plurality of target equipment according to different signal transmission modes. In some embodiments, the target device may include a controller of a ground control center and a target terminal inside the vehicle, the controller may communicate with the in-vehicle log management device through a vehicle-to-ground wireless network, and the target terminal may communicate with the in-vehicle log management device through bluetooth. The signal transmission module in the vehicle-mounted log management device may include a network transmission interface and a bluetooth module, and when receiving the information acquisition request message sent by the target device, the signal transmission mode may be determined by the module that receives the information acquisition request message, and the obtained vehicle-mounted log is sent to the target device according to the signal transmission mode. If the network transmission interface receives the information acquisition request message, the signal transmission mode can be determined to be transmission through the vehicle-to-ground wireless network, and the acquired vehicle-mounted log is sent to the controller through the vehicle-to-ground wireless network. If the Bluetooth module receives the information acquisition request message, the signal transmission mode can be determined to be Bluetooth transmission, and the acquired vehicle-mounted log is sent to the target terminal through Bluetooth. In this way, when the vehicle-ground wireless network is transmitting other data or fails, the target terminal can be used for acquiring the vehicle-mounted log through Bluetooth so as to monitor the voltage change condition and the software running condition of the signal system.
In summary, the present disclosure firstly obtains a vehicle-mounted log of a signal system of a vehicle, and when receiving a signal obtaining request message sent by a target device, firstly determines a signal transmission mode corresponding to the target device, and then sends the obtained vehicle-mounted log to the target device according to the signal transmission mode, where the vehicle-mounted log includes a voltage signal and a software log. According to the method and the system, the collected vehicle-mounted logs are sent to the target equipment according to the signal transmission mode corresponding to the target equipment, when other data are being transmitted or faults occur by the vehicle-to-ground wireless network, the vehicle-mounted logs can be transmitted to the target equipment through the other signal transmission modes, the target equipment can be guaranteed to timely acquire the vehicle-mounted logs, and meanwhile the vehicle-to-ground wireless network is not influenced to transmit other data.
In an application scenario, the implementation manner of step 102 may be:
and under the condition that the network transmission interface receives the signal acquisition request message, determining the signal transmission mode to be transmission through the vehicle-ground wireless network.
And under the condition that the Bluetooth module receives the signal acquisition request message, determining that the signal transmission mode is through Bluetooth transmission.
In another application scenario, the target device includes a controller in a vehicle-to-ground wireless system, and one implementation of step 103 may be:
and under the condition that the signal transmission mode is transmission through the vehicle-to-ground wireless network, the acquired vehicle-mounted log is sent to the controller through the vehicle-to-ground wireless network.
In another application scenario, the target device includes a target terminal, and another implementation of step 103 may be:
and under the condition that the signal transmission mode is Bluetooth transmission, the obtained vehicle-mounted log is sent to the target terminal through Bluetooth.
By way of example, fig. 2 is a schematic diagram of an in-vehicle log management device, and as shown in fig. 2, the signal transmission module may include a network transmission interface and a bluetooth module, and the target device may include a target terminal and a controller in a train-ground wireless system. The controller can be arranged at a ground control center, and a worker can obtain the vehicle-mounted log from the vehicle-mounted log management device through the controller at the ground control center. The target terminal may be a mobile terminal or a fixed terminal provided in the vehicle, and may transmit and receive messages through bluetooth. The Bluetooth module can be connected to a Bluetooth antenna in the vehicle through a feeder line, and the target terminal can acquire a vehicle-mounted log through Bluetooth.
In some embodiments, a worker may determine whether there is a need to immediately download the on-board log based on the needs of train operation and maintenance. If there is no need to immediately download the on-board log, it is optional to download the on-board log by the controller during non-operation of the vehicle. If the requirement of immediately downloading the vehicle-mounted log exists, whether the vehicle-mounted log can be downloaded through the vehicle-to-ground wireless network or not can be further judged, and normal driving of the vehicle is not affected. If the vehicle-mounted log can be downloaded through the vehicle-to-ground wireless network and has no influence on the normal running of the vehicle, the vehicle-mounted log can be downloaded through the controller at the ground control center. If the vehicle-mounted log cannot be downloaded through the vehicle-to-ground wireless network or has influence on normal driving of the vehicle, the vehicle-mounted log can be downloaded at the target terminal through Bluetooth. Therefore, the pressure brought to the vehicle-ground wireless network by transmitting the vehicle-mounted log in the running process of the vehicle can be avoided, and the vehicle-mounted log can still be obtained when the vehicle-ground wireless network is transmitting other data or fails.
When the vehicle-mounted log is downloaded through the controller, a worker can trigger a signal acquisition request message through the controller, the signal acquisition request message is sent to the switch through the vehicle-to-ground wireless network and then sent to the vehicle-mounted log management equipment through the switch, and the vehicle-mounted log management equipment can receive the signal acquisition request message through the network transmission interface. Under the condition that the network transmission interface receives the signal acquisition request message, the vehicle-mounted log management device can determine that the signal transmission mode is transmission through the vehicle-to-ground wireless network, and send the vehicle-mounted log corresponding to the signal acquisition request message to the switch through the vehicle-to-ground wireless network, and then the switch sends the vehicle-mounted log to the controller.
When the vehicle-mounted log is downloaded through the target terminal, a worker can trigger a signal acquisition request message through the target terminal and send the signal acquisition request message to the vehicle-mounted log management equipment through Bluetooth, and the vehicle-mounted log management equipment can receive the signal acquisition request message through the Bluetooth module. Under the condition that the Bluetooth module receives the signal acquisition request message, the vehicle-mounted log management device can determine that the signal transmission mode is Bluetooth transmission, and send the vehicle-mounted log corresponding to the signal acquisition request message to the target terminal through Bluetooth.
FIG. 3 is a flowchart illustrating another method of managing vehicle logs, as shown in FIG. 3, according to an exemplary embodiment, the method may further include, prior to step 103:
and 104, carrying out Bluetooth pairing with the target terminal so as to establish Bluetooth connection with the target terminal.
And step 105, receiving a login request message sent by the target terminal through the Bluetooth connection.
Step 106, in case that the first encryption information in the login request message is matched with the preset encryption information, the second encryption information is randomly generated.
And step 107, sending the second encryption information to the target terminal through Bluetooth connection, so that the target terminal logs in a preset file system according to the second encryption information to acquire the vehicle-mounted log stored in the file system.
For example, a bluetooth pairing may first be performed with the target terminal before communicating with the target terminal via bluetooth, thereby establishing a bluetooth connection with the target terminal. When the target terminal needs to download the vehicle-mounted log, the target terminal can firstly log in a file system of the vehicle-mounted log management equipment, so as to acquire the vehicle-mounted log stored in the file system. In some embodiments, the target terminal may trigger a login request message on a WEB interface of bluetooth login authentication, and send the login request message to the vehicle-mounted log management device through bluetooth, where the vehicle-mounted log management device may receive the login request message sent by the target terminal through bluetooth connection. Under the condition that the first encryption information in the login request message is matched with the preset encryption information, second encryption information can be randomly generated and sent to the target terminal through Bluetooth connection, so that the target terminal can log into a file system of the vehicle-mounted log management device according to the second encryption information. The target terminal may then trigger an information acquisition request message in the file system to download the in-vehicle log from the in-vehicle log management device.
Fig. 4 is a flowchart illustrating another method of managing an in-vehicle log according to an exemplary embodiment, and as shown in fig. 4, the voltage signal includes: a first voltage signal and a second voltage signal. Step 101 may be implemented by the steps of:
in step 1011, a first voltage signal is obtained, the first voltage signal being indicative of a voltage provided by the vehicle to a power module of the signaling system.
Step 1012, a second voltage signal is obtained, where the second voltage signal is used to indicate the voltage provided by the power module to other modules in the signal system except for the power module.
The voltage signals may include a first voltage signal and a second voltage signal, and the acquisition module may acquire, in real time, the first voltage signal corresponding to a power supply voltage for indicating a power supply voltage provided by the vehicle to a power supply module of the signal system and the second voltage signal corresponding to a power supply voltage for the power supply module to other modules in the signal system except the power supply module through a hard wire, so as to monitor, in real time, a fluctuation condition of the power supply voltage of the signal system, and when the power supply voltage of the signal system is abnormal, quickly locate a cause and a range of the fault.
FIG. 5 is a flowchart illustrating another method of managing vehicle logs, according to an exemplary embodiment, as shown in FIG. 5, the method further comprising:
and step 108, compressing the vehicle-mounted log.
And step 109, storing the compressed vehicle-mounted log into a storage module.
For example, the CPU module may compress the vehicle-mounted log collected by the collection module, and then store the compressed vehicle-mounted log in the storage module, so as to save a storage space of the storage module. In this way, when the information acquisition request message sent by the target device is received, the compressed vehicle-mounted log can be taken out from the storage module and sent to the target device in a target transmission mode.
In summary, the present disclosure firstly obtains a vehicle-mounted log of a signal system of a vehicle, and when receiving a signal obtaining request message sent by a target device, firstly determines a signal transmission mode corresponding to the target device, and then sends the obtained vehicle-mounted log to the target device according to the signal transmission mode, where the vehicle-mounted log includes a voltage signal and a software log.
