[0001] The present invention belongs to the field of communication technology, and in particular relates to a method and device for detecting the operating status of a communication terminal. Background Art

[0002] There are many types of vehicles in the airport with different uses. From the perspective of vehicle functions, they can be divided into several categories, such as passenger transportation, baggage handling, aircraft services, pavement maintenance and security patrols. These vehicles play an important role in the daily operation of the airport, ensuring the safety and convenience of passengers' travel and the normal operation of the airport. Usually, the management of airport vehicles is to deploy an on-board station powered by external power on the airport vehicle. Through the information transmission of the on-board station, the airport vehicle is assigned tasks, high-precision location reporting, etc., and vehicle management and illegal driving detection can also be carried out.

[0003] However, after long-term operation, the operating status of the vehicle-mounted station may change (power supply or wired connection status) due to human or non-human factors (vibration, harness dragging, etc.). The existing treatment method mainly takes preventive measures, that is, using aviation plug sockets, aviation plug cables, etc., and then strengthening them through physical reinforcement to prevent loosening or human removal.

[0004] For example, patent CN102508444A provides a vehicle-mounted desktop control device with a reversible tabletop and a method for reversing the tabletop. The control device can be used in harsh vehicle-mounted environments (such as vibration and impact of oil logging vehicles). The control device includes a main housing, an operating tabletop, a control panel, a computer, a display, and a locking device. The operating tabletop is installed on the main housing through a rotating shaft. The tabletop rotates freely around the rotating shaft and can be locked to the main housing in both horizontal and vertical states. The operating tabletop is opened horizontally when in use and flipped to a vertical state when not in use. The computer is installed at the bottom of the main housing, and a control panel is set at the front of the computer. The front panel can be opened to maintain the computer unit. The display is installed at the top of the main housing, and the display is fixed to the main housing by screws. The device has a compact structure, a small size, strong maneuverability, is easy to carry, and is easy to operate, effectively realizing the miniaturization of the desktop control device in the vehicle.

DETAILED DESCRIPTION

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two.

[0025] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0026] For the vehicle-mounted stations deployed in the airport vehicles, the management and behavior detection of the vehicles in the airport are realized by dispatching tasks to the vehicles and reporting the high-precision location. Due to the external power supply and external plug-in connection method of the vehicle-mounted station, it is easy to have abnormal situations during use. The abnormal situation may be caused by human factors or by non-human factors such as power disconnection or external accessories being unplugged.

[0027] In order to realize real-time monitoring of the operating status of communication terminals such as vehicle-mounted stations and promptly identify abnormal situations of external power supply and plug-in and unplug connection status of external wired cables, it is necessary to start from factors such as the communication positioning achieved by the vehicle-mounted station and the power status of the vehicle-mounted station itself, and combine the established wired detection circuit to detect the wired connection status of the communication terminal in a specific operating mode, and report the detected abnormal situation to the background to facilitate timely and effective inspection and repair.

[0028] like Figure 1 As shown, by setting an application processor 2, the operation status of the communication terminal 1 is detected. The application processor 2 is connected to the communication terminal 1. In a certain embodiment, the connection between the application processor 2 and the communication terminal 1 is a wired connection. The application processor 2 receives signal data from the communication terminal 1 and analyzes the signal data, thereby realizing the judgment and identification of the operation status of the communication terminal 1.

[0029] The operation status of the communication terminal can be detected by the application processor. Figure 2 As shown, the present invention provides a method for detecting the operating status of a communication terminal, which is applied to an application processor connected to the communication terminal, and specifically includes the following steps: Based on the analysis of the received negative logic level transmission signal, the real-time positioning information of the communication terminal is obtained; Acquire the power information of the communication terminal, and integrate the real-time positioning information and power information of the communication terminal to give the current operation mode of the communication terminal, where the operation mode of the communication terminal includes full-function operation and standby operation; Based on the analysis of the current operation mode of the communication terminal, the wired connection state of the communication terminal is detected according to the wired detection circuit; By tracking the changes in the wired connection status of the communication terminal, early warning processing is performed on the operation status of the communication terminal.

[0030] For communication terminals such as vehicle-mounted stations, they realize the functions of vehicle positioning and management. The operation status detection of the communication terminal needs to start from the functions it realizes, consider indicators such as positioning and power, and use this to analyze the current operation mode of the vehicle-mounted station. If it is in standby mode at this time, then detect and analyze the wired connection status and analyze the reason for the standby mode. This can achieve high-precision and real-time detection of the operation status of the communication terminal, which is convenient for subsequent timely maintenance and repair.

[0031] Wherein, based on the analysis of the received negative logic level transmission signal, the real-time positioning information of the communication terminal is obtained, which specifically includes the following steps: Setting a first communication parameter of the application processor, establishing a signal transmission connection with the positioning module, wherein the signal transmission is a negative logic relationship, the positioning module is a preset module of the communication terminal, and the positioning module performs initialization processing after being preset, and sets a first communication parameter corresponding to the application processor; Receive and parse the communication terminal positioning information or communication terminal positioning observation information sent by the positioning module to obtain the real-time positioning information of the communication terminal.

[0032] like Figure 1 As shown, the positioning module 11 of the communication terminal can be an external hardware device or an embedded device. Here, the specific form of the positioning module is not limited. For example, the positioning module can be a GPS positioning module, which receives satellite signals through its internal radio frequency antenna, and calculates the location information of the communication terminal through the propagation time difference (TOF) or arrival time (TOA) of the satellite signal, thereby enabling the acquisition of real-time positioning information of the communication terminal. At the same time, due to different types of positioning modules, the application processor may receive the positioning information of the communication terminal or the positioning observation information of the communication terminal; if the received positioning observation information of the communication terminal (i.e., pseudo-range data and carrier phase data) is the communication terminal, then the corresponding algorithm is used for processing to provide the real-time positioning information of the communication terminal.

[0033] In order to ensure that the positioning module and the application processor can correctly send and receive data, it is necessary to initialize the positioning module and set the first communication parameters for the application processor and the positioning module at the same time. The first communication parameters include baud rate, data bit, stop bit and check bit. With the above setting of the first communication parameters, the high-precision positioning module and the application processor can correctly send and receive data, ensuring the accuracy and reliability of positioning data transmission.

[0034] At the same time, for the serial communication standard between the application processor and the communication terminal, a negative logic relationship can be used. The negative logic relationship means that logic "1" represents a lower voltage and logic "0" represents a higher voltage. In a specific communication standard, logic "1" corresponds to a voltage of -5V to -15V, and logic "0" corresponds to a voltage of +5V to +15V. This negative logic relationship can ensure the stability and reliability of the positioning signal during the transmission process, thereby realizing effective data transmission between the communication terminal and the application processor within a shorter distance.

[0035] In addition, after obtaining the real-time positioning information of the communication terminal, the following steps are also included: Sending a status query command to the positioning module, wherein the status query command is used to inquire about the health status of the embedded antenna in the positioning module; Receive the status response returned by the positioning module, parse the status response, and give the status analysis result of the positioning module.

[0036] After acquiring the real-time positioning information of the communication terminal, the operating status of the high-precision positioning module can be ensured through the interaction between the application processor and the communication terminal to ensure the accuracy of the positioning information. In a specific embodiment, the interaction between the application processor and the communication terminal is the status query process. The application processor sends a status query command to the positioning module of the communication terminal. The format of the status query command can be a specific string or byte sequence, which is used to request the high-precision positioning module to return the health status of the embedded antenna. Of course, the logic sent by the status query command can also adopt a negative logic relationship, that is, logic "1" corresponds to a voltage of -5V to -15V, and logic "0" corresponds to a voltage of +5V to +15V.

[0037] The corresponding unit inside the application processor parses the received status response, identifies the health status of the antenna, and gives the status analysis result of the positioning module. If the status response indicates that the antenna connection is normal, the application processor can continue to receive and process the positioning information sent by the positioning module normally. If the status response indicates that the antenna connection is abnormal, the application processor can take corresponding measures, such as prompting the user to check the antenna connection, recording fault information, or entering fault mode.

[0038] like Figure 3 As shown, the real-time positioning information and power information of the communication terminal are integrated to give the current operation mode of the communication terminal, which specifically includes the following steps: providing an initial operation mode of the communication terminal through the positioning information of the communication terminal; Based on the acquired power information of the communication terminal, the initial operation mode of the communication terminal is corrected to give the current operation mode of the communication terminal.

[0039] The operation mode of the communication terminal includes at least two modes: full-function operation and standby operation. Among them, full-function operation means that the communication terminal is in normal working state, and all functions are activated and available; standby operation refers to a low-power consumption state when no communication or other operations are performed.

[0040] After acquiring the real-time positioning information of the communication terminal, the application processor performs cumulative tracking and analysis on the real-time positioning information, and gives whether the communication terminal is currently in full-function operation or standby operation mode through the change of the real-time positioning information of the communication terminal. For example, if the real-time positioning information does not change within the first threshold time, it is preliminarily determined that the communication terminal is in standby operation mode, otherwise, it can be considered that the communication terminal is in full-function operation mode.

[0041] Of course, the operation mode of the communication terminal may also include other modes, and the matching of the real-time positioning information and the operation mode of the communication terminal may also be limited by setting other threshold times, threshold values ​​of changes in real-time positioning information, etc. However, the change of the operation mode of the communication terminal by the threshold time and the threshold value of the change in real-time positioning information may be inaccurate in certain specific scenarios. For example, when a vehicle undergoing airport maintenance is undergoing maintenance work, the real-time positioning information will not change for a long time due to the maintenance scenario and difficulty. Therefore, after the initial operation mode of the communication terminal is given by the positioning information of the communication terminal, the initial operation mode of the communication terminal can also be corrected by the power information of the communication terminal to obtain the final operation mode of the communication terminal.

[0042] Therefore, based on the acquired power information of the communication terminal, the initial operation mode of the communication terminal is corrected to give the current operation mode of the communication terminal, which specifically includes the following steps: Obtain the power information of the communication terminal and provide the power health status of the communication terminal; Based on the power health status of the communication terminal, the initial operation mode of the communication terminal is corrected to give the current operation mode of the communication terminal.

[0043] Specifically, if Figure 4 As shown, obtaining the power information of the communication terminal and providing the power health status of the communication terminal specifically includes the following steps: Setting a second communication parameter of the application processor to establish a signal transmission connection with the power module, wherein the power module is a preset module of the communication terminal, the power module includes a power meter unit, an external power supply and a built-in power supply, and setting the second communication parameter corresponding to the application processor in the power meter unit; Sending an instruction to read the power information and a clock signal to the power meter unit, wherein the instruction to read the power information includes the power meter unit address, which is used for the power meter unit to perform address matching judgment, respond, and provide the communication terminal power information; Receive and analyze the communication terminal power information sent by the power module, and perform threshold analysis on the communication terminal power information; Based on the threshold analysis results, the working status of the external power supply and the built-in power supply are matched, and the power health status analysis results of the communication terminal are given.

[0044] like Figure 1 As shown, the power module 12 of the communication terminal includes an external power supply 122 and a built-in power supply 123, wherein the external power supply 122 mainly provides the power used by the communication terminal, and the built-in power supply 123 serves as a backup power supply. When the external power supply 122 fails, it provides a preset power supply, and the preset power supply can put the communication terminal in a standby operation mode.

[0045] In a specific embodiment, the preset power level is the threshold for threshold analysis of the power information of the communication terminal. If it is higher than the preset power level, it means that the external power supply is in working condition and the power health status of the communication terminal is good. If it is equal to the preset power level, or even no power is measured, it means that only the built-in power supply is working or both the external power supply and the built-in power supply are not working. At this time, the power health status of the communication terminal is poor and requires manual intervention for processing.

[0046] The power module 12 also includes a power meter unit 121, and the power module 12 transmits signals with the application processor 2 through the power meter unit 121. In the transmission between the power meter unit and the application processor, the application processor acts as a master device, and the power meter unit acts as a slave device. The hardware connection between the application processor and the power meter unit is through a serial data line and a serial clock line, and then the second communication parameters of the master device and the slave device are set respectively to establish signal transmission between the master device and the slave device. Among them, the second communication parameters include clock frequency and slave device address. As the master device, the application processor sends an instruction to read power information to the power meter unit, wherein the instruction to read power information includes the address of the power meter unit as a slave device; after receiving the instruction to read power information sent by the application processor, the power meter unit performs matching judgment through the power meter unit address in the instruction to read power information, responds, and feeds back the power information of the communication terminal to the application processor; the application processor parses the received data and gives the power health status analysis result of the communication terminal.

[0047] The application processor is connected to the fuel meter unit through a serial data line and a serial clock line. The application processor sends a command to read the fuel meter unit through the serial data line, and also receives the communication terminal fuel meter unit feedback from the fuel meter unit through the serial data line. At the same time, when the application processor sends a command to read the fuel meter unit through the serial data line, the application processor also sends a clock signal to the fuel meter unit through the serial clock line. If the preset time is exceeded and the communication terminal fuel meter unit feedback from the fuel meter unit is not received through the serial data line, the result of no communication response is fed back.

[0048] In a specific application scenario, the external power supply in the power module is connected to the communication terminal through a wired cable. At this time, the connection status of the wired cable plays a key role in the operation mode of the communication terminal. When the application processor obtains the current operation mode of the communication terminal, if it is finally determined to be standby operation, it will detect the wired connection status of the communication terminal based on the analysis results of the power health status of the communication terminal, and determine the operation status of the communication terminal by tracking the changes in the wired connection status of the communication terminal.

[0049] To detect the wired connection status of the communication terminal in real time, a wired detection circuit needs to be set up. Specifically, Figure 5 As shown, the wired detection circuit 21 includes a first detection circuit 211 and a second detection circuit 212; the first detection circuit 211 is connected to the first contact of the communication terminal socket 13, one end of the wired cable 3 is connected to the second detection circuit 212, and the other end of the wired cable 3 is used to connect to the second contact of the communication terminal socket 13, and when the other end of the wired cable 3 contacts the second contact of the communication terminal socket 13, the wired cable 3 is connected to the first detection circuit 211 through the second contact and the first contact; The first detection circuit 211 includes: a first detection line 2111 and a pull-up module 2112 connected to the first detection line 2111, one end of the first detection line 2111 is connected to the application processor pin 22, and the other end is connected to the first contact of the communication terminal socket 13, for transmitting a level signal to the application processor pin 22; The second detection circuit 212 includes: a DC power supply 2121, an identification resistor 2122 and a ground terminal. One end of the identification resistor 2122 is connected to the wired cable 3, and the other end is respectively connected to the negative electrode of the DC power supply 2121 and the ground terminal. The positive electrode of the DC power supply 2121 is connected to the wired cable 3.

[0050] The communication terminal is provided with a socket, and the type of the socket can be an aviation plug socket. The wired cable can use an aviation plug cable, and the aviation plug cable is connected to the aviation plug socket to realize the connection between the external power supply and the communication terminal. In order to realize the real-time detection of the wired connection status of the wired cable, a wired detection circuit is set. The wired detection circuit is divided into two parts, wherein the first wired detection circuit receives and analyzes the level signal and gives the wired connection status, and the second wired detection circuit can provide an external power supply and can review and verify the wired connection status according to the voltage drop across the identification resistor.

[0051] At this time, the first contact of the communication terminal socket is connected to the second contact, and the external power supply in the power module of the communication terminal is integrated into the second detection circuit, that is, the DC power supply in the second detection circuit.

[0052] Among them, Figure 6 As shown, there are at least two pull-up modules 2112, each of which includes: a DC constant voltage power supply 21121 and a pull-up resistor group 21122 corresponding to the DC constant voltage power supply 21121, each pull-up resistor group 21122 includes at least one pull-up resistor, and each pull-up resistor in each pull-up resistor group 21122 is in parallel relationship; Each DC constant voltage power supply 21121 is connected to a corresponding pull-up resistor group 21122 to form a pull-up module 2112 , and each pull-up module 2112 is connected to the first detection line 2111 in parallel.

[0053] The first detection line is connected to both the first contact of the communication terminal socket and the pull-up module. The pull-up module is set in the first detection circuit. When the second detection circuit is connected to the ground terminal, when the wired cable is not connected to the communication terminal socket, the DC constant voltage power supply gives a high level signal through the pull-up resistor group, and the level signal transmitted by the first detection circuit to the application processor pin is a high level; when the wired cable is connected to the communication terminal socket, the grounded second detection circuit gives a low level, and the level signal transmitted by the first detection circuit to the application processor pin is a low level.
