Description

  The present invention relates to an electronic apparatus, an apparatus inspection apparatus, an apparatus inspection method, a program, and a recording medium, and more specifically, an electronic apparatus having a display unit, an apparatus inspection apparatus and an apparatus inspection for inspecting the operation of the electronic apparatus. The present invention relates to a method, a program to be incorporated in the electronic device, and a computer-readable recording medium on which the program is recorded.

  Electronic devices are usually distributed after operation confirmation and adjustment of various set values in a production line. In the inspection process for confirming such operation and the adjustment process for adjusting various set values, depending on whether the inspection equipment side and the electronic device side are connected by wire or communicated by a wireless control signal such as infrared rays, The electronic equipment is controlled from the inspection facility side.

  In consideration of communication reliability, a wired connection may be employed. In addition, it is necessary for adjustment of setting values by connecting the inspection equipment side and the electronic device (product) side to the external bus by wire in the mechanized production line and making the connection mutually communicable. Various exchanges are possible.

  As an example of wireless connection in a production line, Patent Document 1 discloses a technique related to bidirectional communication in automatic production line facility control using a contactless data transmission method. In the automatic production line equipment control system described in Patent Document 1, production control is performed using bidirectional communication between a base plate on which a product to be produced is placed and moved on the line and a device outside the line. When exchanging information, in order to separate the forward and return signals of bidirectional communication, the phase of the signal waves of the forward and return paths is adjusted to be different at the transmission position with respect to the overlapping portion of the signals. Patent Document 2 discloses a technique for switching between a communication channel of an in-vehicle electronic device and a communication channel of an inspection device thereof according to the transport position of the vehicle.

  The two-way communication technology including Patent Documents 1 and 2 can be used in the inspection / adjustment process as described above. However, in the inspection process, only the processes that require two-way communication such as adjustment of set values are required. There are also processes that do not require two-way communication. For example, this is a process that only requires a simple instruction to be sent to the electronic device side, for example, to execute an operation transition such as a mode change. Then, in the process of simply transmitting such a simple instruction to the electronic device side, an attempt is made to establish a communication channel and perform two-way communication even with a wireless connection as well as with a wired connection. Then, it is necessary to connect once for each process, which is considerably large in terms of equipment.

  Therefore, in such a simple process, not only wired connection is not effective, but also wireless connection for bidirectional communication is not effective. Therefore, the production line is manned using unidirectional radio signals including infrared remote control signals (R / C signals). In a manned production line, even if an infrared R / C signal is used, it is possible for a person to determine whether or not a product (electronic device) is operating normally in each process. Therefore, the situation of shifting to the adjustment / inspection of each process with the reception error of the infrared R / C signal can be avoided in the case of a manned production line.

In addition, to reduce costs, controlling the electronic equipment to be inspected with such a unidirectional radio signal not only reduces the production line facilities but also reduces the number of personnel required for the production line. Will also be required. In order to satisfy such requirements, an automated production line (unmanned production line) is used, and in its adjustment / inspection process, wireless signals (especially unidirectional wireless signals such as infrared rays) are transferred to various operation transitions from the equipment side to the product side. R / C signal) may be used.

As described above, it is preferable that the inspection for performing the predetermined display in the present invention is an inspection as to whether to shift to the setting process before the actual inspection is performed. Further, when the display means is an image display means for displaying an image as in this example, it is preferable that the predetermined operation includes an operation related to display of the display means itself. The operation related to the display of the display means itself corresponds to simple channel switching.

  Further, instead of executing the predetermined display on the display unit 15, the electronic device 1 may be provided with an audio output unit and the control unit 12 may be provided with an audio output control unit so that predetermined audio is output. In this case, it can be realized by processing the noise of the conveyor of the production line.

  FIG. 1 is a block diagram showing a configuration example of an electronic apparatus and an apparatus inspection apparatus for inspecting the electronic apparatus according to an embodiment of the present invention, and FIG. 2 is displayed on a display unit of the electronic apparatus of FIG. FIG. 3 is a screen example before receiving the R / C signal, and FIG. 3 is a screen example after receiving the R / C signal displayed on the display unit of the electronic device of FIG.

  An electronic apparatus 1 illustrated in FIG. 1 includes a receiving unit 11 having a signal receiving unit, a control unit 12 having a control unit, and a display unit 15 having a display unit. The remote unit (remote transmitter) 10 receives the receiving unit 11. It can be controlled via The control unit 12 includes a display control unit 13 having display control means. In addition, the electronic device 1 includes various processing units 14 for executing a function that is an original purpose. In other words, the various processing units 14 are units that execute processing (target processing in the electronic device 1) that is the purpose of using the electronic device 1 and processing associated therewith, and are controlled by the control unit 12. However, when the electronic device 1 is a TV or a display monitor, the target process is mainly executed by the display unit 15.

  On the other hand, the device inspection apparatus 2 includes a transmission unit 21 and a display detection unit 22 and can detect a predetermined display displayed on the display unit 15 of the electronic device 1. A predetermined display example will be described later with reference to FIGS. Therefore, the display detection unit 22 is disposed at a position facing the display unit 15 on the production line of the electronic device 1. As the facing position, when the display unit 15 of the electronic device 1 is mounted and transported in parallel on the production line, the display detection unit 22 is provided so that a predetermined display on the display unit 15 can be confirmed. It is good to arrange | position a sensor part toward the production line side. Further, as the facing position, when the display unit 15 of the electronic device 1 is mounted on the production line and transported downward, the production line is displayed so that a predetermined display on the display unit 15 can be confirmed. It is preferable to provide a cut-out part (hole part) on the mounting base and arrange the display detection part 22 so that a predetermined display can be detected from the lower side. By causing the display unit 15 to flow downward, the distance between the display unit 15 and the display detection unit 22 can be kept constant with respect to each electronic device 1. It can be said that the display detection unit 22 is an identification unit or a light receiving unit that optically identifies and confirms the presence or absence of the predetermined display by the display unit 15 and the predetermined display image.

  The control unit 12 is configured by connecting a microcomputer (hereinafter referred to as a microcomputer) that controls each unit (including display control on the display unit 15) via a bus. The display unit 15 is configured by a display device and the like, and performs predetermined display according to the present invention based on a mode transition instruction or the like, and setting items and contents thereof to assist setting operation in an inspection process after predetermined display. Is displayed.

  Such a microcomputer includes a nonvolatile memory such as a ROM (Read Only Memory) for storing a program including a predetermined display program according to the present invention and a program for processing in the various processing units 14, and the present invention. A non-volatile memory for storing predetermined display data and adjustment values set by wired or wireless communication after a mode transition instruction is connected. Inside the microcomputer, an arithmetic processing unit such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit) and a volatile memory such as a RAM serving as a program execution area are provided.

  The predetermined display program includes a program for causing the arithmetic processing device to execute a display control step for controlling display on the display unit 15, and the display control step is for causing the electronic apparatus 1 to perform a predetermined operation. When the control signal is transmitted wirelessly from the device inspection apparatus 2 of the electronic device 1 and the transmitted control signal is received by the receiving unit 11, the display unit 15 is controlled to perform a predetermined display indicating reception of the control signal. To do.

  As a display example on the display unit 15 before receiving the R / C signal, the video 16 and the predetermined display video 17 may be displayed as illustrated in FIG. 2A, or simply as shown in FIG. Only the video 16 may be displayed as exemplified in FIG. Furthermore, the current mode and channel information may be displayed on the OSD (On Screen Display).

  The reason why the predetermined display video 17 is displayed even before reception of the R / C signal is to make it easy to identify the difference from the predetermined display video 18a to 18f after reception illustrated in FIG. Therefore, the predetermined display image 17 may not be displayed, but it is only necessary to be able to identify the difference between the image 16 that changes after reception and the predetermined display images 18a to 18f, and the image 16 itself is not displayed depending on the inspection process. In such a case, the non-display of the predetermined display video 17 is particularly effective. 2A is displayed at the time of waiting for a remote control signal after the transition from the normal mode to the process (inspection) mode.

  After receiving the R / C signal, predetermined display images 18a to 18f as illustrated in FIGS. 3A to 3F are displayed on the display unit 15. FIG. The predetermined display image 18a is, for example, a red rectangular image, the predetermined display image 18b is, for example, a green rectangular image, and the predetermined display image 18c is, for example, a blue rectangular image, and is color-coded based on a control signal from the transmission unit 21. In the device inspection apparatus 2, the display detection unit 22 may detect whether a predetermined display corresponding to the generated control signal is performed on the display unit 15. Moreover, the predetermined display image after reception may display characters as in the predetermined display images 18d to 18f illustrated in FIGS. In this case, in order to facilitate identification, it is preferable to display a character having a color that can easily identify a difference from the color after coloring a predetermined rectangular area as illustrated. Further, if only the control signals are received in a single order without distinction, the predetermined display image 18 is a white rectangular image, for example, and only a change in brightness as in the OPC sensor is detected. But it is possible.

  Further, it is necessary that the operation in the inspection process (adjustment / inspection process) and the operation performed by the user with the remote controller 10 after shipment can be distinguished by the control unit 12 made of a microcomputer or the like. In other words, if the control unit 12 cannot determine whether the current process is the inspection process or the time of use, a predetermined display will be made even during a user operation.

  In order to make this distinction possible, it is only necessary to provide an inspection mode dedicated to the inspection process in addition to the normal mode when used by the user, and to execute a predetermined display only in the inspection mode. Note that the normal mode described above includes a user adjustment mode in which the user himself / herself sets an adjustment value.

  For example, in the adjustment / inspection process in an automatic production line, when communicating between the equipment inspection device 2 side (equipment side) and the electronic equipment 1 side (product side), a dedicated mode for adjustment / inspection in the process is used. In the dedicated mode, unlike the normal mode, when the electronic device 1 receives the R / C signal, an operation is performed to change the display content at a specific display position on the display screen. This operation may be performed by utilizing an OSD function that the electronic device 1 has as an internal function, for example.

  More specifically, the display screen on the electronic device 1 side is specified when the electronic device 1 side has successfully received an infrared R / C signal for various adjustment / inspection operation transitions from the device inspection device 2 side. The display content of the display position is displayed for about 0.5 seconds from a black pattern illustrated in FIG. 2A, for example, as an RGB single color pattern as illustrated in FIGS. 3A to 3C. A return signal indicating that the infrared R / C signal has been normally received from the electronic device 1 side by detecting a change in display contents at a specific display position on the display screen on the electronic device 1 side by a color sensor on the two side To do. Further, instead of the RGB single color pattern, for example, a character such as “OK” illustrated in FIG. 3D is displayed, and a display character on the display screen is preliminarily registered with a pattern such as a CCD image by a sensor such as a CCD. By performing comparison (pattern matching), a return signal indicating that the infrared R / C signal from the electronic device 1 side has been normally received is obtained. By displaying characters, etc., in addition to making a return signal indicating that the infrared R / C signal from the electronic device 1 has been normally received, several types of equipment and products can be obtained by arranging several character signals in advance. Simple communication on the side is also possible.

  In other words, the control unit 12 performs an operation check of the electronic device (performs an operation check of the electronic device) in addition to the normal mode in which the electronic device 1 is controlled to execute a normal operation when used by the user. Control) in the inspection mode. And the display control part 13 is good to control to perform a predetermined | prescribed display with respect to the control signal received by the receiving part 11, only when driving in test | inspection mode. In this way, the predetermined display in the inspection mode can correspond to each control signal and can be a display different from that in the normal mode.

  As described above, in the present invention, when an infrared R / C signal (other than wired) is used for various operation transitions from the equipment side to the product side in the adjustment / inspection process of the automated (unmanned) line, the product side is in some form the equipment side. A certainty of communication is provided by returning a return signal. The return signal is returned from the product side to the equipment side using a display unit such as a display screen. In addition, according to the present invention, the electronic device is provided with a receiving unit for supporting a remote controller, and communication reliability can be provided without adding to the product separately. In addition, since the equipment inspection apparatus side does not become large-scale, the adjustment / inspection process of the automated (unmanned) line does not become large-scale.

  As described above, in the present invention, in the adjustment / inspection process of the automated (unmanned) line, infrared R / C signals (other than wired) can be used for various operation transitions from the equipment side to the product side, and control without connection is possible. Can do. That is, according to the present invention, when an electronic device having a display means is inspected on a production line, a simple control instruction such as operation transition is reliably performed wirelessly and unattended without adding a communication device to the electronic device. It becomes possible.

  Next, the electronic apparatus will be specifically described by taking a television receiver as an example. This television receiver displays video on a display device corresponding to the display unit 15 in FIG. 1 may be an image display unit that displays an image (video), and the electronic device 1 of FIG. 1 may be an image (video) display device. The predetermined operation here may include a basic screen display operation in the image display means.

  FIG. 4 is a block diagram showing a configuration example of a television receiver according to another embodiment of the present invention and a device inspection apparatus for performing the inspection thereof, and FIG. 5 is an external view of the television receiver in FIG. FIG.

  The television receiver 3 illustrated in FIG. 4 includes a tuner 31 that modulates a broadcast signal received by an antenna, an external input terminal 32 that inputs a video signal and an audio signal from an external device, and a tuner 31 and an external input terminal 32. The selector 33 for selecting the signal input in the above, the decoder 34 for demodulating the video signal selected by the selector 33, the video processing circuit 35 for correcting the video demodulated by the decoder 34, and the OSD An OSD processing circuit 36 that reads display data from the nonvolatile memory 38 and the like and superimposes it on the video corrected by the video processing circuit 35; and a liquid crystal panel 37 for displaying the video output from the OSD processing circuit 36. Further, a microcomputer 39 for controlling these devices and OSD display control is connected on the bus 41.

  Further, the microcomputer 39 includes a non-volatile memory 40 such as a ROM for storing a predetermined display program according to the present invention and a program including a processing program in another processing circuit, and the predetermined display data according to the present invention. And a nonvolatile memory 38 such as an EEPROM for storing various adjustment values, and a microcomputer 39 and a central processing unit such as a CPU and MPU and a volatile memory such as a RAM serving as a program execution area Is provided. Further, the microcomputer 39 is connected with a user operation unit (not shown) and a light receiving unit 42 for receiving a user operation signal from the remote controller 43.

  When the light receiving unit 42 receives a control signal from the light emitting unit 51 in the device inspection apparatus 5, the microcomputer 39 controls the liquid crystal panel 37 to perform a predetermined display by executing the predetermined display program. The predetermined display as illustrated in FIG. 3 displayed on the liquid crystal panel 37 is detected by the display detection sensor 52 of the device inspection apparatus 5 as a return signal of the control signal emitted by the light emitting unit 51. The predetermined display may be obtained by causing the power lamp 45 and the on-timer lamp 46, which are provided together with the light receiving unit 42, the brightness sensor 44, and the like, to blink on the front surface of the liquid crystal panel 37 at predetermined intervals or in predetermined patterns. .

  When the adjustment / inspection process for the television receiver 3 is a screen reversal operation confirmation process for checking whether the display screen is reversed horizontally and vertically, as an example of the mode transition contents, switching between left and right and up and down Is mentioned. As for the left / right / up / down switching, the display may be switched by performing a display rotated 90 ° clockwise from a normal display, and further a display rotated 90 ° clockwise. A direct transition to be reversed may be performed. Such a mode transition can be a return signal by displaying a black and white colored display in at least four grid-like areas as a predetermined display and detecting the display by the display detection sensor 52.

  In addition, in the following adjustment / inspection process in which the mode transition itself is difficult to detect as a display on the liquid crystal panel 37, it is preferable to separately prepare predetermined display data and display it with the transition.

  When the adjustment / inspection step is a step of checking the operation of the OPC (brightness sensor 44) for checking whether the screen brightness changes according to the brightness at the installation location, Examples include ON / OFF switching of OPC and writing of the voltage from the OPC detection cell into the memory inside the product (instead of the brightness of the screen, the detection cell voltage to the microcomputer).

  When the adjustment / inspection process is a time setting / backup function operation confirmation process for performing in-product backup during a short power failure or the like, an example of the mode transition content is an operation check next to this function. That is, time setting, writing of the time after power failure recovery to the memory inside the product, and the like can be mentioned. Here, since only the clock function is functioning internally during the backup operation, the backup function is confirmed based on whether or not this operation is normal.

  When the adjustment / inspection process is an auto-preset operation confirmation process for checking whether or not the channel transmitted from the RF signal from the antenna can be picked up, as an example of the mode transition contents, an auto-preset The start of operation can be mentioned. Note that the auto-preset operation itself is already incorporated into the television receiver 3 as software or firmware.

  When the adjustment / inspection process is an external AV input / output terminal inspection process for checking whether or not the signal from the external AV input terminal of the product is normally displayed, an example of mode transition content is AV Examples include switching of external AV inputs such as -1 / AV-2 / (AV-3) (in a direct transition mode instead of a toggle operation) and switching of input / output modes of the AV-2 terminal. In this case, it is also possible to detect the mode transition itself as a display on the liquid crystal panel 37 based on information OSD displayed on the upper right of the liquid crystal panel 37 or the like.

  When the adjustment / inspection step is a gain adjustment step at the time of antenna input for performing gain adjustment at the time of AGC (Auto Gain Control) -OFF of the AD converter at the time of an RF reception signal, The adjustment operation can be started. The gain adjustment operation itself is already incorporated into the television receiver 3 as software or firmware so as to be executable.

  When the adjustment / inspection process is a process of confirming a bright spot / black spot panel defect in which a panel defect of bright spot / black spot is inspected, as an example of mode transition contents, output of an inspection product internal pattern signal and signal switching Is mentioned.

  In the present invention, in the adjustment / inspection process of the automated (unmanned) line, the infrared R / C signal (other than wired) can be used for such a transition from the equipment side to the product side or other operations. Connection control is possible. In other words, according to the present invention, even in an image display device such as the television receiver 3, simple control instructions such as operation transition can be reliably performed wirelessly and unattended without adding a separate communication device to the electronic device. It becomes possible.
