Description

[Detailed description of the invention] Technical field The present invention relates to a vehicle-mounted video/audio device.

Background Art Traditionally, radio receivers and cassette decks have been widely known as in-vehicle audio equipment, but recently digital audio discs (hereinafter referred to as DADs), which can be used even in places with vibrations, have become popular.
With the development of the f-rake, it became possible to install a disc player in a car, which was previously considered impossible. On the other hand, regarding video equipment, in-vehicle television receivers are already commercially available, and video recorders and video disc players can also be used for in-vehicle use.

It would be convenient if many of these audio and video devices could be installed together in a car, since there are many information sources, but if each device had its own operation section and display section, operability and visibility would be poor. Problems will also arise in terms of driving safety. In addition, 1. Since there is only one space available inside an automobile, it is impossible to arrange all the devices near the driver's seat.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an in-vehicle video/audio device that improves operability and space factor by collectively controlling the system using a common operation section and control section. With the goal.

The in-vehicle video/audio device according to the present invention includes a plurality of video/audio devices with different functions, a common operation unit for remotely controlling these devices, operation mode information of the plurality of devices,
A common display section that displays video information and operation information of the operation section is connected by a communication line, and the plurality of video/audio devices are collectively controlled via this communication line.

Example Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, for example, a trunk room 2 of an automobile 1 contains audio equipment such as a cassette deck 3, a DAD, etc.
It includes a player 4, an AM/FM receiver 5, a video device such as a TV receiver 6, a host computer that centrally controls these devices, an amplifying section 8 that amplifies audio signals output from each device, and the like. The main body of the device is stored.

The operation section 9 of each of these devices is separated from the main body of the device and divided into areas near the driver's seat 10, for example, a meter panel section 11 and a console section 12, so that the driver's seat 10 can select the device, command the operation mode, etc. It is located.

In order to simplify operation, the minimum number of keys necessary for operating each device is regularly arranged on the operation unit 9, and by sharing many of these keys for operating each device, the number can be reduced. And the dedicated space can be reduced. An operating section 13 having substantially the same function as the operating section 9 on the driver's seat 10 side is also provided on the back of the driver's seat IO so that it can be operated not only in the driver's seat 10 but also in the rear seat.

The display unit 4 consisting of CILT, dot matrix or multilayer liquid crystal is separated from the main body of the device and the operation unit 9,
For example, it is integrated into the storage unit 15 and displays operation information of the operation unit 9, operation mode information of each device stored in the trunk 2, video information from the TV receiver 6, etc. . The speaker 16 is arranged behind the rear seat. In addition, in FIG. 1, the operation section 9
Although the display section 4 and the display section 4 are provided separately, it is also possible to configure both 9 and 14 in one piece and arrange them near the driver's seat 10, as shown in FIG.

In FIG. 3, a cassette deck 3, a DAD player 4, and an AM/FM receiver 5 are arranged in a trunk room 2.
, the TV receiver 6, the preamplifier 8A and the graphic equalizer 8B constituting the amplifier section 8 are each controlled by a controller 3α,
They are connected by a common interface path line 17 via 4α, 5α, 6α, 8α and 8h. An operating section 9 and a display section 14 disposed near the driver's seat are also connected to the pass line 17 via a key manual encoder 9A and a display controller 14α, respectively. The path line 17 is composed of a plurality of signal lines such as a data bus and an address bus, and is centrally controlled by a host computer. Each of the above unit controllers has a bidirectional path line 17.
At the same time, it outputs necessary information data to the pass line 17. The host computer 7 controls whether each unit controller is in the data reception state or the data transmission state, and only one unit (equipment) on the path line is always in the data transmission state, and two or more units are in the data transmission state. It is managed so that data is not sent at the same time. All units other than those in the sending state are set to receive mode.

On the device main body side, the cassette deck 3 has an O-1 change function that stores multiple cassette tapes, selects one of them, and automatically sets it to the playback position, and receives a control signal issued from the host computer. The configuration is such that the input controller 3α is used to select the output mode and operation mode.
459, etc., but it will not be described in detail here because it is not the gist of the present invention. Similarly, DAD player 4
has an auto-change function that accommodates a plurality of discs and selects one of them and automatically sets it in the playback device, and the controller 4α is configured to select the disc, select the operating mode, etc. ing. As a DAD grayer having an auto-change function, the one proposed by the applicant in Japanese Patent Application No. 56-67396 or the like can be used. In this way, cassette deck 3 and I) AD7°
If the layer 4 has an auto-change function, it is extremely convenient because it saves the effort of changing cassette tapes and discs, and allows continuous performance automatically by simply operating the operating section 9 from the driver's seat 10.

Audio signals output from the cassette deck 3, I) AD player 4, and AM/FM receiver 5 are supplied to a speaker 16 through an amplifier 8 consisting of an audio amplifier 8A, a graphic equalizer 8B, and an audio amplifier 8C. '1゛■The audio signal output from the receiver 6 is outputted from the amplifier section 8 by /? It is supplied to the speaker 16 via Waranzo 8C,
Further, the video signal output from the TV receiver 6 is supplied via a video signal line 18 to a display controller 14a that controls the display unit 14. This allows the display unit 14 to display general television broadcast images.

As shown in FIG.
A group of function keys 9α for selecting any one of the receivers 6, cassette deck 3 or I) AD7' layer 4 PLAY, 5TOP operation or AM/FM receiver 5
A group of mode keys 9h for switching AM/FM, and a group of select keys for selecting the cassette number of the cassette deck 3, the disc number of the DAD Soraya 4, the preset station of the AM/FM receiver 5, or the channel of the TV receiver 6. 9c, a tuning key 9d for tuning the AM/FM receiver 5, a polygon key 9C, and a power switch 9.
f is provided, and the operated key emits light.

It is also possible to install a video disc player, video tape recorder, etc. on the device main body, and even if there are a large number of devices, it is possible to efficiently identify the devices by focusing on the data on the pass line 17. It becomes possible to communicate. If you want to display information from each device even if it is still receiving data, you can superimpose the information signal on the TV video signal and display the information at any position on the screen of the display unit 14. It can also be displayed. Furthermore, the storage location of the main body of the device is not limited to the inside of the trunk compartment 2, but may be under the seat, in the back seat, or the like.

Next, the basic operation of the one-piece system will be explained.

All operations of this system are performed manually using the keys on the operating section 9, so there is no need to increase the number of operating sections even if the equipment is additionally expanded. When commanding the mode, when a key is operated, the key manual encoder 9A generates a data signal according to the key manual input, and at the same time requests the host computer 7 for permission to use the pass line 17, and the host combination -
According to the command on evening 7, the above-mentioned key manual data code is output to the pass line.

All other device controllers are in the receiving state, so
Each of the above data codes is decoded, it is determined whether the data is the own command or not, and if the data is the own command, the mode is changed to the corresponding mode. For example, when using 8 bits as a data line, the upper 3 b
It can be used as a header to access the controller of each device. Furthermore, the lower 5 bits are assigned to the instruction code. top 3
If the bit starts with "001", the header of the data is for the deck controller 3a, for example, and this causes the deck controller 3α to be assigned to the lower 5
The bit data is decoded, and the cassette deck 3 operates accordingly. In addition, the deck controller 3a,
In response to the operation, the display data is displayed using the same method.
No Z line 1 under the command of host combination P-Tuff
Output to 7. In that case, the display data will be, for example, 8-hat data where the header starts with "°' o o o".The display unit 14 will display based on the same data.In addition, if the display data cannot be sent at once sends data repeatedly as necessary.The audio signal system is
Conventionally, it is connected as a signal line.

Note that the usage of the data lines shown in the above embodiment is merely an example, and the number of bits, code allocation, etc. may be optimized depending on the situation. Since the operating section 9 is composed only of a key switch and an encoder circuit, it can be made smaller and lighter, which increases the degree of freedom in mounting and allows it to be mounted freely on the inside of a door, etc.

Effects As explained above, according to the present invention, a common system control line can be used! <Since we use a pass line and centrally control the host computer via this pass line, it is easy to add and expand the system, and since you can freely set everything other than the operation section and display section, the system can be expanded easily. Even if the device becomes multi-functional, the operating section and display section can be shared, making centralized control and display possible. Furthermore, since it has a versatile pass line configuration, even if new equipment is developed in the future, it can be easily incorporated into the system.
