Description

Method and system for recovering from motion errors

[0001] The present disclosure relates to a method and system for recovering an operation error of a vehicle data collection terminal, and more particularly, to a method and system for recovering an operation error by determining the operation status of a monitored module by a monitoring module of a vehicle data collection terminal, and initializing the monitored module in response to determining that the operation status of the monitored module is a malfunction.

[0002] Typically, terminals that control vehicles or collect vehicle data typically include a broadband communication module (e.g., WCDMA, LTE LoRa) for server connectivity, an MCU (Micro-Controller Unit) module for controlling terminal functions, and a short-range communication module (e.g., BLE, WiFi) for connectivity with the driver's smartphone or other short-range devices. Furthermore, because vehicle data collection terminals are mounted on vehicles and move with them, they can malfunction or stop working, just like mobile communication devices.

[0003] Conventional technologies utilize a central control system, such as a server, to detect malfunctions in specific modules and remotely issue a reset command. However, this approach is limited when a problem occurs in a broadband communication module. In other conventional technologies, if a module malfunctions, the entire vehicle data collection terminal, not just the module in question, is reset. This approach requires a long reboot time, during which the vehicle data collection terminal cannot perform any functions.

[0004] The present disclosure provides a method and system (device) for recovering from an operation error to solve the above-described problem.

[0005] The present disclosure can be implemented in various ways, including as a method, a device (system), or a computer program stored on a readable storage medium.

[0006] According to one embodiment of the present disclosure, a method for recovering from an operation error may include a step of determining, by a monitoring module of a vehicle data collector terminal, an operation status of a monitored module of a vehicle data collector terminal, and a step of initializing the monitored module in response to the monitoring module determining, by the monitoring module, that the operation status of the monitored module is a malfunction.

[0007] According to one embodiment of the present disclosure, the step of determining the operating status of the monitored module may include a step of determining, by the monitoring module, whether an alive signal is received from the monitored module, and a step of determining, by the monitoring module, whether the monitored module is malfunctioning based on whether the alive signal is received.

[0008] According to one embodiment of the present disclosure, the step of determining whether the monitored module is malfunctioning may include the step of requesting, by the monitoring module, transmission of an alive signal to the monitored module in response to a delay in reception of the alive signal, and the step of determining the operating state of the monitored module as malfunctioning when the monitoring module fails to receive a response to the request for transmission of the alive signal.

[0009] According to one embodiment of the present disclosure, a waiting time of a monitoring module receiving an alive signal and a repetition number of an alive signal transmission request are preset, and when the monitoring module does not receive an alive signal during the waiting time, it is determined that reception of the alive signal is delayed, and a step of requesting the monitoring module to transmit an alive signal can be performed repeatedly by the repetition number.

[0010] According to one embodiment of the present disclosure, each of the monitoring module and the monitored module may include a power pin for receiving power from a power supply and an initialization pin for receiving an initialization command signal for initializing the module.

[0011] According to one embodiment of the present disclosure, the step of initializing the monitored module may include the step of transmitting, by the monitoring module, an initialization command signal to an initialization pin of the monitored module.

[0012] According to one embodiment of the present disclosure, a vehicle data collection terminal includes a first module, a second module, and a third module that are interconnected, and when the first module is a monitored module, the third module may be a monitoring module, and when the second module is a monitored module, the first module may be a monitoring module, and when the third module is a monitored module, the second module may be a monitoring module.

[0013] According to one embodiment of the present disclosure, when the operating status of each of the first module and the second module is determined to be a malfunction, the third module can initialize the first module, and the initialized first module can initialize the second module.

[0014] A computer program stored in a computer-readable recording medium may be provided to execute a method according to one embodiment of the present disclosure on a computer.

[0015] A system for recovering from an operation error according to one embodiment of the present disclosure comprises a power supply unit for supplying power, a monitored module, and a monitoring module for determining an operation state of the monitored module, wherein the monitoring module can be configured to initialize the monitored module in response to determining that the operation state of the monitored module is a malfunction.

[0016] A system for recovering from an operation error according to one embodiment of the present disclosure comprises a power supply unit for supplying power, a first module, a second module connected to the first module, and a third module connected to the first module and the second module, wherein the first module determines an operation state of the second module, the second module determines an operation state of the third module, and the third module determines the operation state of the first module, and in response to determining that the operation state of the second module is a malfunction, the first module initializes the second module, in response to determining that the operation state of the third module is a malfunction, the second module initializes the third module, and in response to determining that the operation state of the first module is a malfunction, the third module initializes the first module.

[0017] According to some embodiments of the present disclosure, operational errors can be recovered using core components inherent in vehicle data collection terminals, without the need for additional chips or circuits for malfunction detection. This reduces the power consumed by the vehicle data collection terminal to recover from operational errors. Furthermore, the cost of building an operational error recovery system can be reduced.

[0018] According to some embodiments of the present disclosure, when initializing the entire vehicle data collection terminal due to a malfunction, the time required to recover from a malfunction can take tens of seconds. However, by initializing only the specific module in which the malfunction occurred, the time required to recover from the malfunction can be shortened to tens of milliseconds (ms). Accordingly, the time required for function interruption due to recovery from the malfunction can be reduced, thereby improving the performance of the vehicle data collection terminal. Furthermore, since the monitoring module monitors the monitored module in a cyclical structure, the operation errors of all modules can be recovered as long as the operation status of all modules is not malfunctioning.

[0019] The effects of the present disclosure are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs (referred to as “one skilled in the art”) from the description of the claims.

For example, the system may be comprised of one or more server devices. As another example, the system may be comprised of one or more cloud devices.

[0035] In the present disclosure, 'each of the plurality of As' or 'each of the plurality of As' may refer to each of all components included in the plurality of As, or may refer to each of some components included in the plurality of As.

[0036] FIG. 1 is a schematic diagram illustrating the configuration of a vehicle data collection terminal (100) capable of self-recovering operational errors according to one embodiment of the present disclosure. As illustrated, the vehicle data collection terminal (100) may include a first module (110), a second module (120), a third module (130), and a power supply unit (140) that supplies power. In addition, the first module (110), the second module (120), the third module (130), and the power supply unit (140) may be connected to each other.

[0037] The likelihood of a vehicle data collection terminal malfunctioning due to a simultaneous failure of its core components—the MCU module, the broadband communication module, and the short-range communication module—is extremely low. In other words, a malfunction in one or two of the MCU module, the broadband communication module, and the short-range communication module could cause the entire vehicle data collection terminal to malfunction. Accordingly, the present invention provides a method for recovering from a vehicle data collection terminal malfunction by interconnecting three modules and cyclically monitoring the operational status of each module.

[0038] In one embodiment, the first module (110), the second module (120), and the third module (130) may be core components of the vehicle data collection terminal (100). For example, the first module (110) may be a broadband communication module for interfacing with a server. In addition, the second module (120) may be an MCU (Micro-Controller Unit) module for controlling the functions of the vehicle data collection terminal (100). Additionally, the third module (130) may be a short-range communication module for interfacing with a driver's smartphone or a short-range device. The above-described first module (110) to third module (130) are merely examples and are not limited thereto, and the first module (110) to third module (130) may include various modules.

[0039] In one embodiment, the monitoring module and monitored module of the vehicle data collection terminal (100) may be configured in a cyclical structure. For example, if the first module (110) is a monitored module, the third module (130) may be a monitoring module. Furthermore, if the second module (120) is a monitored module, the first module (110) may be a monitoring module. Recursively, if the third module (130) is a monitored module, the second module (120) may be a monitoring module.

[0040] In one embodiment, the monitoring module can determine the operational status of the monitored module. Specifically, the monitoring module can determine whether an alive signal is received from the monitored module. Based on whether the alive signal is received, the monitoring module can determine whether the monitored module is malfunctioning. An example of the monitoring module determining whether the monitored module is malfunctioning is described in detail below with reference to FIG. 4.

[0041] In one embodiment, in response to determining that the operational status of the monitored module is a malfunction, the monitoring module may initialize the monitored module. In this case, the monitoring module may transmit an initialization command signal to the monitored module. Here, the initialization command signal may refer to a signal for resetting the power of the module. For example, if the second module (120) fails to transmit an alive signal to the first module (110) due to an operational error, the first module (110) may transmit an initialization command signal to the second module (120), thereby initializing the second module (120). Alternatively, the monitoring module may transmit the initialization command signal of the monitored module to the power supply unit (140). Accordingly, the power supply unit (140) may temporarily cut off the power supplied to the monitored module, thereby initializing the monitored module.

[0042] This configuration allows for the recovery of operational errors using core components inherent in vehicle data collection terminals, without the need for additional chips or circuits for malfunction detection. This reduces the power consumed by vehicle data collection terminals to recover from operational errors. Furthermore, the cost of building an operational error recovery system can be reduced.

[0043] FIG. 2 is a block diagram showing the internal configuration of a vehicle data collection terminal (100) according to one embodiment of the present disclosure. As illustrated, the vehicle data collection terminal (100) may include a power supply unit (210), a monitoring unit (220), and a monitored unit (230). Here, each of the monitoring unit (220) and the monitored unit (230) may include at least one of the modules included in the vehicle data collection terminal (100) (e.g., the first module (110), the second module (120), the third module (130) of FIG. 1, etc.). In addition, a specific module may be a monitoring unit (220) and at the same time a monitored unit (230). For example, referring to FIG. 1, the first module (110) may be a monitoring unit (220) for the second module (120), and at the same time a monitored unit (230) for the third module (130).

[0044] In one embodiment, the power supply unit (210) can supply power to the monitoring unit (220) and the monitored unit (230). Specifically, the power supply unit (210) can supply power to the monitoring unit (220) and the monitored unit (230) through the power pin (222) of the monitoring unit (220) and the power pin (232) of the monitored unit (230). In addition, the power supply unit (210) can also cut off power to the monitoring unit (220) and the monitored unit (230). Accordingly, the power supply unit (210) can also initialize the monitoring unit (220) and the monitored unit (230).

[0045] In one embodiment, the monitoring unit (220) can monitor the monitored unit (230). That is, the monitoring unit (220) can determine the operating status of the monitored unit (230). Specifically, the monitored unit (230) can transmit an alive signal to the monitoring unit (220). The monitoring unit (220) can determine whether the monitored unit (230) is malfunctioning based on whether or not it receives an alive signal from the monitored unit (230).

[0046] In one embodiment, the monitoring unit (220) and the monitored unit (230) may each include initialization pins (224, 234). When the monitoring unit (220) determines that the operating status of the monitored unit (230) is malfunctioning, the monitoring unit (220) may transmit an initialization command signal to the initialization pin (234) of the monitored unit (230) to initialize the monitored unit. In response to receiving the initialization command signal, the monitored unit (230) may initialize itself. Alternatively, the monitored unit (230) may be initialized by temporarily cutting off the power supplied from the power supply unit (210).

[0047] FIG. 3 is a diagram illustrating an example of a method for a monitoring module to determine the operating status of a monitored module in a cyclical structure according to one embodiment of the present disclosure. In one embodiment, the monitoring module and the monitored module of a vehicle data collection terminal may be configured in a cyclical structure. For example, if the first module (310) is a monitored module, the third module (330) may be a monitoring module. Additionally, if the second module (320) is a monitored module, the first module (310) may be a monitoring module. Recursively, if the third module (330) is a monitored module, the second module (320) may be a monitoring module.

[0048] In one embodiment, the monitoring module can determine the operating status of the monitored module. Specifically, the monitoring module can receive an alive signal (312, 322, 332) from the monitored module. If the operating status of the monitored module is malfunctioning, the monitored module may fail to transmit the alive signal (312, 322, 332). Therefore, the monitoring module can determine whether the monitored module is malfunctioning based on whether or not the alive signal (312, 322, 332) is received from the monitored module. An example of determining whether or not the monitored module is malfunctioning is described in detail below with reference to FIG. 4.

[0049] For example, if the first module (310) does not receive the alive signal (322) from the second module (320), the first module (310) may determine the operating state of the second module (320) as a malfunction. Similarly, if the second module (320) does not receive the alive signal (332) from the third module (330), the second module (320) may determine the operating state of the third module (330) as a malfunction. In addition, if the third module (330) does not receive the alive signal (312) from the first module (310), the third module (330) may determine the operating state of the first module (310) as a malfunction.

[0050] In one embodiment, in response to determining that the operational status of the monitored module is malfunctioning, the monitoring module can initialize the monitored module. Specifically, the monitoring module can transmit an initialization command signal to the monitored module. In this case, the monitored module can receive the initialization command signal via the initialization pin. Accordingly, the monitored module can initialize itself. Alternatively, the monitored module can be initialized by temporarily cutting off power supplied from the power supply via the power pin.

[0051] For example, if the first module (310) determines that the operating status of the second module (320) is a malfunction, it can transmit an initialization command signal (314) to the second module (320). Similarly, if the second module (320) determines that the operating status of the third module (330) is a malfunction, it can transmit an initialization command signal (324) to the third module (330). In addition, if the third module (330) determines that the operating status of the first module (310) is a malfunction, it can transmit an initialization command signal (334) to the first module (310).

[0052] In one embodiment, the operating status of two of the three modules (310, 320, 330) may be malfunctioning. For example, the operating status of each of the first module (310) and the second module (320) may be malfunctioning. In this case, in response to determining that the operating status of the first module (310) is malfunctioning, the third module (330) may initialize the first module (310). In addition, the first module (310), which is initialized and operating normally, may initialize the second module (320) in response to determining that the operating status of the second module (320) is malfunctioning.

[0053] In FIG. 3, the direction in which the monitoring module monitors the monitored module is depicted as clockwise, but this is not limited thereto. For example, if the first module (310) is a monitored module, the second module (320) may be a monitoring module.

[0054] With this configuration, while initializing the entire vehicle data collection terminal due to a malfunction can take tens of seconds to recover from a malfunction, by initializing only the specific module where the malfunction occurred, the time required to recover from the malfunction can be shortened to tens of milliseconds (ms). Accordingly, the time for function interruption due to recovery from a malfunction can be reduced, thereby improving the performance of the vehicle data collection terminal. Furthermore, since the monitoring module monitors the monitored module in a cyclical structure, any module's operating status can be recovered from a malfunction as long as it is not malfunctioning.

[0055] FIG. 4 is a flowchart illustrating an example of a method in which a monitoring module (410) determines and initializes an operating state of a monitored module (430) according to one embodiment of the present disclosure. In one embodiment, the monitored module (430) may transmit an alive signal (436) to the monitoring module (410). Specifically, the monitored module (430) may determine whether a transmission period of the alive signal has been reached (432). If the transmission period of the alive signal has been reached, the monitored module (430) may transmit an alive signal to the monitoring module (410). In addition, the monitored module (430) may determine whether transmission of the alive signal has been completed (434). If the monitored module (430) has not completed transmission of the alive signal, the monitored module (430) may retransmit the alive signal (436) to the monitoring module (410).

[0056] In one embodiment, the monitoring module (410) can determine whether to receive an alive signal from the monitored module (430) (412). If the monitoring module (410) receives an alive signal from the monitored module (430), the monitoring module (410) can continue to determine whether to receive an alive signal from the monitored module (430).

[0057] In one embodiment, if the monitoring module (410) does not receive an alive signal from the monitored module (430), the monitoring module (410) may determine whether reception of the alive signal from the monitored module (430) is delayed (414). Specifically, the monitoring module (410) may wait for reception of the alive signal for a preset waiting time. If the monitoring module (410) receives an alive signal within the waiting time, the monitoring module (410) may continue to determine whether reception of the alive signal from the monitored module (430) is delayed.

[0058] In one embodiment, the monitoring module (410) may request the monitoring module (430) to transmit an alive signal in response to a delay in receiving an alive signal (416). In this case, the monitoring module (430) may transmit an alive signal to the monitoring module (410) as a response signal to the alive transmission request. In addition, the monitoring module (410) may request the monitoring module (430) to transmit an alive signal a preset number of times. Additionally, the monitoring module (410) may determine whether a response to the alive signal transmission request (i.e., an alive signal) has been received (418). If the monitoring module (410) receives a response to the alive signal transmission request, it may continue to determine whether the monitoring module (430) has received an alive signal.

[0059] In one embodiment, if the monitoring module (410) fails to receive a response to the request for transmitting an alive signal, the monitoring module (410) may determine that the operating status of the monitored module (430) is malfunctioning. Accordingly, the monitoring module (410) may transmit an initialization command signal (420) to the monitored module (430). The monitored module (430) may initialize itself in response to the initialization command signal (420). Alternatively, the monitored module (430) may be initialized by temporarily cutting off power supplied from the power supply unit through the power pin.

[0060] FIG. 5 is a flowchart illustrating an example of a method (500) according to one embodiment of the present disclosure. In one embodiment, the method (500) may be performed by at least one processor of a vehicle data collection terminal. The method (500) may begin with the processor determining the operating status of a monitored module of the vehicle data collection terminal by the monitoring module (S510). Specifically, the processor may determine, through the monitoring module, whether an alive signal is received from the monitored module. Furthermore, the processor may determine, through the monitoring module, whether a malfunction of the monitored module is occurring based on whether an alive signal is received.

[0061] Thereafter, in response to the monitoring module determining that the operational status of the monitored module is malfunctioning, the processor may initialize the monitored module (S520). Here, each of the monitoring module and the monitored module may include a power pin that receives power from the power supply and an initialization pin that receives an initialization command signal for initializing the module. In this case, the processor may transmit an initialization command signal to the initialization pin of the monitored module through the monitoring module.

[0062] In one embodiment, a vehicle data collection terminal may include a first module, a second module, and a third module that are interconnected. If the first module is a monitored module, the third module may be a monitoring module. Furthermore, if the second module is a monitored module, the first module may be a monitoring module. If the third module is a monitored module, the second module may be a monitoring module. Here, if the operating status of each of the first and second modules is determined to be malfunctioning, the third module may initialize the first module, and the initialized first module may initialize the second module.

[0063] FIG. 6 is a flowchart illustrating an example of a method (600) according to one embodiment of the present disclosure. In one embodiment, the method (600) may be performed by at least one processor of a vehicle data collection terminal. The method (600) may begin with the processor setting values ​​necessary for the monitoring module to perform monitoring (S610). Specifically, the waiting time of the monitoring module receiving the alive signal and the number of repetitions of the alive signal transmission request may be preset.

[0064] Thereafter, the processor can receive an alive signal from the monitored module via the monitoring module (S620). In this case, the processor can determine whether the reception of the alive signal is delayed (S630). Specifically, if the monitoring module does not receive the alive signal within a preset waiting time, it can be determined that the reception of the alive signal is delayed.

[0065] In response to a delay in receiving an alive signal, the processor may request the monitored module to transmit an alive signal (S640). Thereafter, the processor may confirm a response to the request for transmitting an alive signal from the monitored module (S650). Here, the step of requesting the monitored module to transmit an alive signal may be repeated a preset number of times.

[0066] In one embodiment, the processor may determine that the operational status of the monitored module is malfunctioning if the monitoring module fails to receive a response to the alive signal transmission request. In this case, the processor may initialize the monitored module through the monitoring module (S660).

The medium may be one that continuously stores a computer-executable program or one that temporarily stores it for execution or download. In addition, the medium may be various recording means or storage means in the form of a single or multiple hardware combinations, and is not limited to a medium directly connected to a computer system, but may also be distributed over a network.

In addition, examples of other media may include recording or storage media managed by app stores that distribute applications, sites that supply or distribute various software, servers, etc.
