Description

Black Box Inspection System {System for Inspecting Black Box}

One embodiment of the present invention relates to a black box inspection system.

The contents described below merely provide background information related to the present embodiment and do not constitute prior art.

Recently, as the use of a black box has become popular, it is a trend that most vehicles are equipped with a black box. The black box captures and stores a driving image while the vehicle is turned on, or captures and stores a parking image while the vehicle is parked even when the vehicle is turned off.

Since the black box needs to capture high-definition images in order to identify objects (licensing plates, etc.) in the captured images, the file size of the captured images increases and takes up a lot of storage capacity. When the black box stores a driving video or a parking video, due to the storage capacity of the internal storage, the previously stored video is deleted and a new video is stored.

Conventional black boxes are directly inspected by inspectors to determine whether or not they are out of order. For example, the inspector manually inspected whether buttons on the black box were pressed well and whether screen recording was successful.

In the conventional black box inspection method, as shown in FIG. 1, the inspector directly checks whether the corresponding function operates normally while viewing the rear LCD of the black box and pressing buttons in a predetermined order.

The operator proceeds with the next inspection step by step while pressing the button of the black box directly by hand. If the operator confirms the occurrence of a defect, the inspection must be started from the beginning while pressing the button on the black box again. Since the operator checks the version information of the black box directly with the naked eye, there is a high possibility of human error. Since one worker inspects one black box, there is a problem that the inspection cost increases because the input of workers is required to increase production.

This embodiment transmits a plurality of preset inspection items to a plurality of TMDs as a command in a state where a plurality of TMDs and a plurality of black boxes are connected one-to-one, so that a plurality of black boxes can be simultaneously inspected, and a command is received. To provide a black box inspection system that can reduce the work space of the black box and shorten the inspection time by automatically inspecting inspection items corresponding to commands in a black box and checking the inspection results. has a purpose

According to one aspect of the present embodiment, a black box inspection device for generating and transmitting commands corresponding to a plurality of inspection items set to a preset type in order to inspect a plurality of black boxes; a black box connected to the jig to receive the command and transmit a response and result corresponding to the command; Provides a black box inspection system comprising a; TMD (Test Module Device) connected to the black box one-to-one and relaying the command, the response, and the result between the black box and the black box inspection device. .

As described above, according to the present embodiment, in a state where a plurality of TMDs and a plurality of black boxes are connected one-to-one, a plurality of preset inspection items are transmitted as commands to the plurality of TMDs to simultaneously inspect a plurality of black boxes. The black box that receives the command automatically inspects the inspection item corresponding to the command and checks the inspection result, thereby reducing the work space of the black box and shortening the inspection time. It works.

The black box inspection system according to the present embodiment includes a black box inspection device 210, a TMD 220, and a black box 230. Components included in the black box inspection system are not necessarily limited thereto.

The black box inspection device 210 refers to a device that inspects inspection items preset in the black box 230 via the TMD 220 . The black box inspection device 210 communicates with a plurality of TMDs 220 using Transmission Control Protocol (TCP). The black box inspection device 210 communicates with the TMD 220 through UART (Universal Asynchronous Receiver/Transmitter) communication.

The black box inspection device 210 generates and transmits commands corresponding to a plurality of inspection items set to a preset type in order to inspect a plurality of black boxes 230 .

The black box inspection device 210 checks whether the front camera, rear camera, screen recording, recording screen playback, speaker, microphone, screen, LED, LCD, voice recognition, and voltage measurement are defective. The black box inspection device 210 can be connected to a plurality of TMDs 220 . The black box inspection device 210 can simultaneously check defects in a plurality of black boxes 230 using a plurality of TMDs 220 .

The black box inspection device 210 is connected to a plurality of TMDs 220, classifies the plurality of black boxes 230 by serial numbers (SN), outputs them on the screen, and displays a separate process for each inspection item. output the UI

The black box inspection device 210 automatically inspects inspection items in order based on preset programming. The black box inspection device 210 transmits a command to check inspection items to the black box 230 according to preset programming. The black box inspection device 210 receives a response packet and a result packet corresponding to a command for checking inspection items from the black box 230 . The black box inspection device 210 checks inspection items based on a response corresponding to a command.

The black box inspection device 210 is connected using a separate jack connecting the rear camera of the black box 230. The black box inspection device 210 communicates by connecting to one pin that is not actually used while connecting the rear camera of the black box 230.

When the black box inspection device 210 is connected to the black box 230, it transmits and receives signals for inspecting the black box 230 and inspection items.

The black box inspection device 210 inspects the black box 230 using a type of inspection program installed in a computer. The black box inspection device 210 transmits a command to inspect inspection items to the black box 230 in the order of a plurality of lists corresponding to the inspection items using an inspection program. The black box 230 performs a test corresponding to the command received from the black box test device 210 to generate a test execution result, generates a response signal including the test performance result, and sends it to the black box test device 210. send.

The black box inspection device 210 checks whether or not there is a defect among inspection items based on the response signal received from the black box 230 . The black box inspection device 210 is connected to the black box 230 one-to-one. The black box inspection device 210 transmits an inspection start command to perform inspection of the black box 230 .

When the black box inspection device 210 transmits a command to check an inspection item to the black box 230, the command type is divided into sync and async and transmitted.

Sync among the command types means a command type that completes inspection by immediately receiving a response (examination result) corresponding to the command from the black box 230 . Among the command types, sink refers to a command type that can move on to the next check item only when a response is received.

The black box inspection device 210 transmits a sync type command to the black box 230 and then receives a response corresponding to the sync type command from the black box 230 to process a command corresponding to the next inspection situation. there is. For example, the black box checking device 210 transmits a sync type command to check the model test start to the black box 230 . After receiving the sync type command, the black box 230 immediately generates a response including a result of checking the model test start and transmits it to the black box inspection device 210 .

The black box inspection device 210 receives a response corresponding to a sync type command from the black box 230 and immediately checks whether a corresponding inspection item is defective. When the black box inspection device 210 transmits a sync type command to the black box 230, the inspection of the corresponding inspection item is completed only when a response corresponding to the sync type command is received from the black box 230.

Among command types, Async means a command type that completes inspection by receiving a response (examination result) corresponding to a command from the black box 230 with a delay beyond a preset threshold. Async among command types means a command type that can move on to the next checkpoint without immediately receiving a response (even if it is received later).

Even if the black box checking device 210 transmits an A-sync type command to the black box 230 and does not receive a response corresponding to the A-sync type command from the black box 230, the sync type corresponding to the next inspection situation commands can be processed. For example, when the black box inspection device 210 transmits an as-sync type command for key press check to the black box 230, the black box 230 determines whether the corresponding key is pressed until the inspector directly presses the button. While waiting, when the button is pressed, a corresponding response is generated and transmitted to the black box inspection device 210. For example, when the black box inspection device 210 transmits an as-sync type command for checking gravitational acceleration to the black box 230, the black box 230 waits until the inspector moves the black box 230, , When a motion is detected, a corresponding response is generated and transmitted to the black box inspection device 210.

Among command types, Async is basically not completed when a response is not received from the black box 230 . Among command types, Async sets a timeout. The black box checking device 210 waits for a timeout period when there is no response from the black box 230 corresponding to the Async type command after transmitting the Async type command to the black box 230. .

The black box inspection device 210 performs negative processing (NG) on the inspection item when the timeout time corresponding to the Async type command elapses. When the black box inspection device 210 performs negative processing (NG) on the inspection item, the progress of the corresponding process is temporarily stopped and then the inspection is performed again. The black box inspection device 210 operates by repeating the re-inspection a preset number of times.

Since the black box inspection device 210 takes waiting time to execute an Async type command, an order is arranged based on a preset algorithm so that time is not overlapped according to all inspection items. The black box inspection device 210 arranges an Async type command in the middle of all inspection items.

For example, when the black box inspection device 210 transmits a reset command among the inspection items of commands to the black box 230, the black box 230 does not immediately perform a reset but for a timeout period (20 to 30 seconds). While waiting, a response corresponding to the command of the Async Time is received from the black box 230 .

Among the inspection items of commands, reset means a command to turn the power off and then turn it on again. The black box inspection device 210 may transmit reset among inspection items of a command to the black box 230 in a sync type or an as sync type.

When the black box inspection device 210 transmits the reset to the black box 230 as an as-sync type command, the black box 230 waits without immediately performing a reset, and all sync-type commands requested to be processed earlier If processed, it performs a reset.

When the black box checking device 210 transmits the reset to the black box 230 as an as-sync type command, the black box 230 does not immediately reset and waits for the sync-type command requested to be processed previously to be processed. Even if it is, if a predetermined time elapses, the reset is performed.

When the black box checking device 210 transmits the reset to the black box 230 as a sync type command, the black box 230 performs the reset regardless of the previously requested command.

The black box inspection device 210 may inspect the black box 230 in the shortest time by combining a sync type command and an as sync type command according to a preset algorithm. The black box inspection device 210 combines a sink type command and an as sink type command corresponding to a command to determine an essential malfunction among commands to determine the total failure of the black box 230 according to a preset algorithm to black out the black box in the shortest time. Box 230 can be inspected.

The black box inspection device 210 combines sink-type commands and as-sync-type commands corresponding to commands for determining selective malfunction among commands for determining total failure of the black box 230 according to a preset algorithm to obtain the shortest possible time. The black box 230 can be inspected.

The black box inspection device 210 selects only commands responsible for a specific function among commands for determining overall failure of the black box 230 . The black box inspection device 210 sets the type of a command responsible for a specific function to sync or as-sync so that a defect specific to a specific function can be quickly identified. The black box inspection device 210 arranges commands responsible for a specific function set to sync or async according to a preset algorithm so that the black box 230 can be quickly inspected.

The black box inspection device 210 generates a command to directly check a recorded image while the SD card is inserted into the black box 230 . The black box checking device 210 generates a command for checking the video and audio by replaying the recorded video while the SD card is inserted into the black box.

The black box inspection device 210 generates an Async type command having a first waiting period 1110, a second waiting period 1120, and a third waiting period 1130 and transfers it to the black box 230.

The TMD 220 is connected to the black box 230 one-to-one and relays commands, responses, and results between the black box 230 and the black box inspection device 210. When connected to the black box 230, the TMD 220 communicates with one of the connection terminals of the rear camera of the black box 230 using a data cable. The TMD 220 receives a command from the black box inspection device 210 through UART (Universal Asynchronous Receiver/Transmitter) communication, converts the UART into LIN (Local Interconnect Network) communication, and transmits the command to the black box 230.

The TMD 220 transmits a command to the black box 230 using a command packet.

When the TMD 220 is connected to the black box 230, it is connected in a 1-wire communication method using one remaining pin among the rear camera connection terminals of the black box 230. The TMD 220 converts the command received from the black box inspection device 210 from UART to LIN using an automated system. The TMD 220 is connected to the rear camera connection port of the black box 230 with a cable to transmit commands.

The TMD 220 transmits a command to the black box 230, receives a response corresponding to the command from the black box 230, and then applies a handshaking method of determining OK or NG.

The TMD 220 converts UART communication into Local Interconnect Network (LIN) communication and communicates with the black box 230. The TMD 220 serves to relay a command transmitted from the black box inspection device 210 to the black box 230 and a response transmitted from the black box 230 to the black box inspection device 210.

The black box 230 is attached to the jig 310. The black box 230 receives a command from the TMD 220 using a cable connected to the rear camera connection port and then converts LIN into UART. When connecting the black box 230 with the TMD 220, communication is easily possible by connecting a cable to a rear camera connection port of the black box 230 without removing the case of the black box 230.

The black box 230 is coupled to the jig 310 to receive a command and then transmits a response and result corresponding to the command. The black box 230 receives a command from the TMD 220 through LIN communication and converts it into UART communication.

When the command corresponding to the command packet is normally received, the black box 230 generates an ACK packet and transmits it to the TMD 220. When the command corresponding to the command packet is not normally received, the black box 230 generates a NACK packet and transmits a signal to the TMD 220 . When the command is normally received, the black box 230 performs an inspection corresponding to the command packet, generates a result packet, and transmits a signal to the TMD 220.

When receiving a command including a reset among test items, the black box 230 does not immediately perform a reset by turning the power off and then on again, and waits until all sync type commands requested to be processed are processed before resetting the black box 230. or when a predetermined period of time elapses even if a sync type command requested to be processed in advance is not processed, a reset is performed.

The black box 230 receives an Async type command having a first waiting period 1110, a second waiting period 1120, and a third waiting period 1130 from the black box inspection device 210.

When there is no response to the Async type command, the black box 230 waits until a first waiting interval 1110, which is a general reaction waiting interval until a response occurs. The black box 230 secondarily waits until the first waiting period 1110 when there is no response, until the reset occurs until the second waiting period. The black box 230 thirdly enters the third waiting period when there is no response up to the second waiting period 1120 and operates to defer the response check after reset.

The black box 230 adjusts the second waiting period 1120 to be shorter than the initial setting value when more than n (a preset number) of Async type commands enter the second waiting period 1120 .

The black box 230 groups Async-type commands for which there is no response after a reset is performed into an Async group. The black box 230 re-performs the test request while delaying the as-sync group in a gradually increasing delay unit.

When the black box 230 receives a new input of an Async type command from the black box checker 210 while delaying the processing of a response to the Async group by a gradually increasing delay unit, the delay unit gradually increases. Immediately, without waiting for as long as possible, re-request to check the Async group.

The black box 230 applies an additional check optimization mode so that when there is no response to the Async-type command (first Async-type command), a new Async-type command (second Async-type command) is applied. ), requests a response to the newly received Async-type command (second Async-type command) until there is a response to the preceding Async-type command (first Async-type command). I never do that.

The jig 310 includes a cradle and a plurality of cables. The jig 310 includes a cradle with a groove capable of holding the black box 230 and cables (audio, power, microphone) capable of operating the black box 230. The cradle forms an open space in which the black box 230 can be attached and detached upward, and forms a separate mounting space in which the black box 230 can be mounted at the bottom. When recording the screen in the black box 230, the jig 310 causes a beep sound to be output from a speaker in order to check whether audio is recorded.

The jig 310 includes a cradle, a power cable, a data cable, and a microphone. The cradle forms a groove through which the black box 230 is mounted. The power cable supplies power to the black box 230. The data cable is connected to the black box 230 to transmit and receive data. The microphone receives the sound output from the black box 230.

The black box inspection device 210 manages inspection specifications (min/max) for each script to prevent errors in determining results. The black box inspection device 210 inspects the black box 230 via the TMD 220 as follows.

When NG occurs in the response received from the black box 230 via the TMD 220, the black box inspection device 210 shortens the re-test time by performing retries as many times as the preset number of times.

The black box inspection device 210 transmits a sync type command for an item with a short inspection time to the black box 230 via the TMD 220, and then responds to the sync type command from the black box 230. The response is received and processed immediately.

The black box inspection device 210 transmits an Async type command for an item that takes a long time to inspect to the black box 230 via the TMD 220, and then sends an Async type command from the black box 230. While waiting until the response corresponding to the command is received, it reduces the overall inspection time by first processing other inspection situations based on the sync type command.

The black box inspection device 210 inspects power on/off control, voltage/current measurement, and speaker volume amplitude measurement for the black box 230 via the TMD 220.

Configuration sets protocol operation method, security setting, data format (format), interface, and API in protocol implementation. The TMD (220) converts the LIN communication method to the UART (115200, 8bit, none, 1bit, none) communication method in configuration. The TMD 220 configures the TMD Command as tmd, ack, nack, and result in the configuration. In the TMD (220) configuration, the starting character is }, the last character is \r\n, and each parameter is separated with a space. In TMD (220) configuration, the starting character of ack and result is $, and the last character is \r\n, and each parameter is separated with a space. The TMD 220 sets the ack and result delivery interval to 1500 ms in the configuration.

The TMD 220 transmits a command to the black box 230 using a command packet.

The black box 230 generates an ACK packet corresponding to the command packet and transmits a signal to the TMD 220 . When a command is normally received from the TMD 220, the black box 230 generates an ACK packet and transfers it to the TMD 220. A timeout for an ACK Packet is set to 5 seconds.

The black box 230 generates a NACK packet corresponding to the command packet and transmits a signal to the TMD 220 . The black box 230 generates a NACK packet and delivers it to the TMD 220 when a test item defined in the command received from the TMD 220 does not exist. The timeout for the NACK Packet is set to 5 seconds.

The black box 230 generates a result packet corresponding to the command packet and transmits a signal to the TMD 220. The black box 230 uses the timeout when a timeout is designated among the inspection items. The black box 230 transmits a result packet together with a defined error code when the test result is negative (ng).

If the inspection state is board, it means the state of inspection in the PCB state. If the inspection state is set, it means the state of inspection in the finished product state where the assembly of the mechanism is completed. If the test state is set (Auto), it means the test state that automatically determines positive (OK) / negative (NG) through the measuring device in the finished product state. If the inspection status is Manual (Set (Manual)), it means that a person visually judges the finished product and inspects it by pressing the OK/Negative (NG) button.

If the type is Sync, it means a processing method that is completed only when a command is delivered and then a check result corresponding to the command is received. If the type is Async, it means a processing method in which a command is transmitted, another check item (Sync Command) is processed, and the result of the Aysnc test is received and completed.

A positive (OK) condition means a case in which a result is delivered before a set delay and satisfies a preset specification. The negative (NG) condition means that if the result is not delivered after waiting for the set delay, the timeout expires and the result value is different from the preset specification.

11 is a diagram showing a waiting section installed in an Async type command according to the present embodiment.

The black box inspection apparatus 210 generates commands corresponding to a plurality of inspection items set to the as-sync type and transmits them to the black box 230. The black box inspection device 210 generates an Async type command having a first waiting period 1110, a second waiting period 1120, and a third waiting period 1130.

The first waiting period 1110 refers to a general reaction waiting period until a response is generated by an operator performing an operation corresponding to the command after receiving a command.

The second waiting period 1120 refers to an additional waiting period when there is no response until the first waiting period 1110 after receiving a command. The second waiting period 1120 means a period of waiting for a response until a reset occurs. Even if the black box 230 receives a command including a reset within the second waiting period 1120, it waits without performing a reset until the second waiting period 1120 elapses.

The third waiting period 1130 refers to a period in which a reset is postponed until after a command is received and no response is generated.

When the black box 230 receives an A-sync type command and there is no response corresponding to the A-sync-type command, it first processes a response corresponding to the sync-type command.

The black box 230 waits until the first waiting period 1110, the second waiting period 1120, and the third waiting period 1130 when there is no response to the as-sync type command, and after reset, the black box 230 performs the as-sync function. Delays the processing of commands of the type.

In other words, in order for a response to the Async type command to exist, the operator must directly check the Async type command output to the black box 230 and then manipulate the button of the black box 230, so that the third waiting period ( 1130), the Async-type commands postponed after that may be processed at once.

In the process of receiving and processing a plurality of commands from the black box inspection device 210, the black box 230 receives n (preset number) or more commands of the Async type and enters the second waiting section 1120. , the second waiting period 1120 is shortened adaptively.

In other words, in the black box 230, when five (preset number) or more of the A-sync-type commands enter the second waiting section 1120, the black box 230 checks the A-sync-type commands and then the black box 230 ) buttons are judged to be in a state where they cannot be operated. Since the black box 230 cannot operate the buttons of the black box 230, it is determined that there is no need to wait as long as the second waiting period 1120, and the second waiting period 1120 is adjusted to be shorter.

12 is a diagram illustrating a method of grouping and processing unprocessed Async-type commands according to the present embodiment.

The black box 230 receives a command including a reset from the black box inspection device 210 . The black box 230 performs a reset according to a command including a reset from the black box inspection device 210 . The black box 230 groups Async-type instructions deferred after reset into an Async group.

The black box 230 re-performs the test request while delaying the as-sync group in a gradually increasing delay unit. The black box 230 delays response processing for an as-sync group in units of a first delay.

When the time of the first delay unit elapses, the black box 230 checks whether a response to a plurality of A-sync type commands included in the A-sync group is input.

The black box 230 checks whether responses of a plurality of A-sync types included in the A-sync group are input after the time of the first delay unit has elapsed. The black box 230 processes a response to the remaining A-sync-type commands included in the A-sync group when there is no response to the first A-sync type command among commands included in the A-sync group. The response process for the as-sync group is delayed again by the second delay unit (delay increased from the first delay unit) without checking .

The black box 230 checks whether responses of a plurality of A-sync types included in the A-sync group are input after the time of the second delay unit has elapsed. The black box 230 processes a response to the remaining A-sync-type commands included in the A-sync group when there is no response to the first A-sync type command among commands included in the A-sync group. The response process for the as-sync group is delayed again by a third delay unit (delay increased from the second delay unit) without checking .

When the black box 230 checks whether responses of a plurality of A-sync types included in the A-sync group are input after a gradually increasing time in units of delay has elapsed, the first command, i.e., a first command among the commands included in the A-sync group, is input. If there is a response to the A-sync type command, responses to the remaining commands among the commands included in the A-sync group are sequentially checked.

When the black box 230 receives a new input of an Async type command from the black box checker 210 while delaying the processing of a response to the Async group by a gradually increasing delay unit, the delay unit gradually increases. Immediately, without waiting for as long as possible, re-request to check the Async group.

If there is a response to the newly input Async-type command, the black box 230 immediately responds to the remaining Async-type commands included in the Async group without delaying the time in units of delay. request again

13 is a diagram illustrating a command processing method when there is an unprocessed Async type command according to the present embodiment.

The black box 230 may apply an additional check optimization mode when there is no response to the Async type command.

The black box 230 applies the additional check optimization mode to respond to the first Async type command even if a second Async type command is newly received when a response to the first Async type command does not exist. When exists, the response to the command of the second Async type is not checked.
