DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic equipment such as audio equipment and video equipment, and more particularly to an electronic equipment capable of easily analyzing the cause of a failure.

[0002]

2. Description of the Related Art Conventional electronic devices, such as audio equipment and video equipment, generate a warning sound when an operation error occurs. For example, when the cassette loading is stopped while using a cassette deck mounted on a vehicle, a warning sound is generated to notify an operation error.

[0003]

As described above, in a conventional electronic device, when an operation error occurs, only an alarm sound is generated. Therefore, it is possible to confirm in what state the operation error has occurred. There was a problem that could not be done.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide an electronic apparatus having a simple configuration that can easily grasp the cause of a failure or abnormal state when it occurs. It is.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides one or a plurality of devices and one or more of device status information such as the operation time, the number of operation errors, and the operation mode of the devices. It is characterized by comprising means for detecting a plurality of devices, storage means for storing the detected device status information, and display means for displaying the stored device status information.

[0006]

The present invention has the above-described configuration, and can display device status information such as the operation time, the number of operation errors, and the operation mode of the device on a display device. It is possible to grasp the durability and the like.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. The present embodiment is an example of a vehicle-mounted audio device including a radio receiver, a cassette deck, and a compact disc (CD) player. FIG. 1 schematically shows a vehicle-mounted audio device according to the present embodiment. In FIG.
Reference numeral 1 denotes a radio receiver, reference numeral 2 denotes a cassette deck, reference numeral 3 denotes a CD player, and reference numeral 4 denotes a control circuit for controlling each of the above-mentioned devices. The control circuit 4 comprises a microcomputer or the like. Reference numeral 5 denotes a key input device for giving an operation command to each of the devices, and the key input device 5 is composed of a plurality of operation buttons. The key input device 5 includes, for example, an operation button for selecting each of the above devices, a reception band (A
M, FM), an operation button for instructing playback, stop, fast-forward (FF, REW), etc. of the cassette deck 2, and an operation button for instructing playback, stop, fast-forward, etc. of the CD player 3. Etc. Reference numeral 6 denotes a display device, which displays a reception band and a reception frequency of the radio receiver 1, an operation mode of the cassette deck 2 and the CD player 3, and the like. Reference numeral 7 denotes a storage device for storing device status information such as the operation time and the number of operation errors of the device detected by the control circuit 4.

FIG. 2 shows the processing in the control circuit 4 of the above embodiment. In FIG. 2, initialization is performed in step A, and a mode is selected in step B. The selection of this mode is performed based on a key input from the key input device 5. Step C is a process for controlling the radio receiver 1. In this step C, for example, when the AM band of the radio receiver is selected by the key input device 5, control for receiving an AM broadcast is performed. Step D is processing for controlling the cassette deck 2, step E is processing for controlling the CD player 3, and step F is processing for performing self-diagnosis.

The control circuit 4 detects the operation time, the number of operation errors, and the like of the device (radio receiver 1, cassette deck 2, CD player 3) selected by operating the key input device 5, and detects the detection. The result is stored in the storage device. In the present embodiment, the following items are detected. (1). Radio reception mode a. The radio reception time is counted by counting the time from when the AM button and the FM button of the key input device 5 are turned on to when the mode is switched to another mode, and the radio reception time is accumulated and stored in the storage device 7. . b. In the radio reception mode, the electric field intensity of the currently received radio broadcast is measured at regular intervals (for example, every hour) and stored in the storage device 7. (2). Cassette mode a. After the operation button for playing the cassette deck is turned on, or after the cassette is transferred to the playback position by the cassette loading mechanism, the play time from when the stop button and the eject button are operated is counted. The time is accumulated and stored in the storage device 7. b. During the elapse of a certain time by operating the eject button, the number of errors in which the cassette could not be ejected is counted,
It is stored in the storage device 7. c. The number of errors in which the reproduction operation has not been started even after a certain period of time has elapsed after the cassette has been inserted into the cassette insertion slot is counted and stored in the storage device 7. (3). CD mode a. After the operation button for playing the CD player 3 is turned on, or after the CD is transferred to the playback position by the loading mechanism, the CD play time from when the stop button and the eject button are operated is counted. The CD play time is accumulated and stored in the storage device 7. B. The number of communication errors between the CD player 3 and the control circuit 4 is counted and stored in the storage device 7.

As described above, the operation time, the number of errors, and the electric field strength of each device are detected and stored in the storage device 7 of the control circuit 4.

FIG. 3 shows a display example in the self-diagnosis processing (step F) in FIG. Key input device 5
When the predetermined two operation buttons are simultaneously operated, the self-diagnosis processing (step F) in FIG. 2 is started. In this state, nothing is displayed on the display device 6 as shown in FIG. Next, when the operation button for displaying data on the display device is operated, “0” is displayed on the display device 6 and the display device enters an input waiting state. Here, when displaying the play time of the CD player, two specific operation buttons of the key input device 5 are operated. By this operation, the CD play time stored in the storage device 7 is read, and FIG.
As shown in (C), after “0”, the CD play time “7”
3 "is displayed. In this way, it can be understood that the cumulative play time of the CD player 3 is 73 hours.

By repeating the above operation, the use time and the number of errors of the radio receiver 1, the cassette deck 2, and the CD player 3 can be displayed on the display device 6. By grasping this display data, It is possible to know the failure location and durability of each device.

Although the above embodiment is directed to a plurality of audio devices such as a radio receiver, a cassette deck, and a CD player, the present invention may be applied to a single device, or to a television receiver, a navigation system, or the like. The present invention may be applied to a video device, and may be added to a vehicle-mounted CD changer, a power amplifier, and the like.

[0014]

As described above, the present invention has the above-described configuration. According to the present invention, it is possible to easily understand the failure location and durability of the equipment, to easily repair the equipment, and to improve the future use of the equipment. This has an advantage that can be reflected in the design.
