Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an address setting method suitable for comprehensively controlling a plurality of electronic devices.

[Summary of the invention]

The present invention relates to an address setting method suitable for comprehensively controlling a plurality of electronic devices, and relates to a system in which a plurality of controlled devices are connected to a control device in a so-called daisy chain. When a different address is set for each address, when a signal for the setting is given from the control device to the controlled device, the signal is sequentially processed in a predetermined manner by each controlled device, making it easy to use. This allows address settings to be performed manually.

[Prior Art] A plurality of controlled devices (electronic devices such as AV devices) are serially connected to a control device such as a controller (
A system is known in which each AV device is connected in a daisy chain (daisy-chain connection) and the operation of each AV device is controlled by a controller.

In this case, an address is assigned (set) to each AV device, and a command signal for instructing a specific AV device to operate from the controller is transmitted together with the address.

Therefore, the addresses set for each AV device must be different.

[Problem to be solved by the invention]

Therefore, the category of AV equipment (for example, TV, VT)
One possible method is to set addresses for each VTR (R, television camera, etc.), but if two VTRs are provided, for example, there is a problem in that it is not possible to set addresses to distinguish between the two.

It is also conceivable to provide a dip switch or the like in each AV device and set the address using the dip switch, but this would complicate the configuration of the AV device and require manual address setting each time. A
When the number of V devices increases, the task becomes extremely troublesome.

An object of the present invention is to provide an address setting method in which each controlled device is set to a different address by simply providing an address setting signal from a control device to the controlled device.

[Means to solve the problem]

In order to achieve the above object, an address setting method according to the present invention includes a plurality of controlled devices (300) (500) capable of transmitting and receiving various signals to and from a desired control device (100).
(700) and (900) are serially connected to the control device (100), and each controlled device (30
0) (500) (700) A signal system is provided in which the various signals transmitted to the final stage controlled device (900) are fed back to the control device (100) via (500) (700) (900), and each controlled device Equipment (300) (500) (700) (90
0), in which a unique address n is set for each of the controllers (100) to a desired controlled device (300).
), when the address setting signal is given to the desired controlled device (300) and the controlled devices (500) (700) (900) connected to the subsequent stages, the address setting signal is It is characterized in that predetermined processing is performed sequentially.

[Effect]

In the address setting method according to the present invention, when an address setting signal is given from a control device to a desired controlled device, the controlled device and subsequent controlled devices perform predetermined processing on the address setting signal. It is done sequentially.

Therefore, for the predetermined processing performed by each controlled device,
By introducing the process of setting a unique address for each controlled device, each controlled device will have a different address.

〔Example〕

Hereinafter, preferred embodiments of the address setting method according to the present invention will be described with reference to the drawings.

FIG. 1 shows a system to which the present invention is applied, in which a controller (control device (100)) is connected to controlled devices (television (300), VTR (5)).
00).

VTRB (700), video camera (900)
) are connected serially.

In this case, each controlled device has a controller (10
A transmitting/receiving device (10) for transmitting and receiving signals with the control device 0) or other controlled devices is built-in.

Note that the transmitting/receiving device (10) is mainly composed of a microcomputer, etc., and is, for example, a V T RA (500
), the device (10) built in the V TRB (700
) is the process of transmitting the processed data to V T RA (
500) control processing such as playback operation, recording operation, etc. is performed.

Also, controller (100), TV (300)
, V T RA (500), V T RB (
700) and the video camera (900) are sequentially connected to bidirectional communication lines (Ll), (LZ), (L:l),
(L, ), and the output signal of the video camera (900) is transmitted through those communication lines (Ll), (LX), (L
a) is fed back to the controller (100) via (L4).

The devices (10) are thus serially connected in sequence,
TV (300) etc. are devices installed in each! (10
) is generally controlled by a controller (100).

So, I bought a VTRB (700) and a video camera (
The configuration of the device (10) will be described by taking as an example a case where the device (900) is controlled by the controller (100).

As understood from FIG. 2, the first terminal (3) and the second terminal (5) provided in the device (10) each have a data (command) signal input/output port (3a). ).

(3b), (5a), (5b) and control signal input/output ports (3c) to (3g), (5c) to (5
g) are installed in parallel.

Then, the command signal output from the controller (100) is input to the boat (3b), and the boat (S
IN) (9b) and stored in the buffer (9B).

In this case, the data signal is a packet signal,
Desired processing is performed on the packet signal stored in the buffer (98) by the CPU (9A), and the signal is output from the boat (SOLIT) (9a).

And between the boat (9a) and the boat (3a),
A switch section (11) is provided that performs a switching operation in which the output signal of the boat (3a) is input from the boat (9a) or the boat (5b).

The switch unit (11) is connected to the boat (3a) when another device (10) is connected after the device F (10).
, (5b), and if they are not connected, short-circuit between the boats (3a) and (9a).

That is, a high-level voltage (for example, 5V) is applied to the boat (3f) of the rear stage W (10), and this voltage is applied to the microcomputer (9) via the boats (3f) and (5d). input into the boat (9g), C
In the PU (9A), a control signal for switching the switch is output from the boat (9f) on the condition that the input at the boat (9g) is high level, so the control signal causes the boats (3a) and (5b) to be output from the boat (9f). The switch section (11) is operated to short-circuit the switch section (11).

On the other hand, when the device (10) is not connected to the latter stage, the voltage at the boats (5d) and (9g) is at a low level, so the switch section (11) short-circuits the boats (3a) and (9a). let

In this case, the packet signal output from the boat (9a) is output from the boat (5a) via the signal line (L), and is also output from the boat (5a) via a line branched from the signal line (L). 3a) is also output.

Furthermore, when the voltage of the boat (9g) is at a high level,
The switch part (13) switches the boat (5d) and the boat (
9d) is short-circuited and is at low level,
The ports (3d) and (9d) are short-circuited.

Therefore, the equipment placed in the final stage! (10) Boat (
The control signal input from 3d) is sent to the previous stage device (1) via boat (9d), boat (9c), and boat (3c)
0) is input to the boat (5d).

Furthermore, the control signal is the same as that of the previous stage! In (10), Bo) (5d), Bo) (9d), Boat (9
c) and the controller (1
00).

The control signal fed back to the controller (100) in this way is transmitted to each device (10) from the controller (100).
) is used to determine whether it is in a state where it can receive data.

Note that a control signal for interrupt processing is input from the boat (3e), and the control signal for interrupt processing is input to the boat (I) of the microcomputer (9).
NT) (9e).

In addition, for the latter device (10), the boat (3e)
The control signal branched from baud) (5f), baud (
3e) and taken into the boat (9e).

In the device (10) configured as described above, a packet signal from the controller (100) is input from the boat (3b) and stored in the buffer (9B), and after predetermined processing is performed, the packet signal is input from the boat (9a). ), the boat (5a), and the boat (3) of the downstream device (10) via the cable (30).
b).

In the subsequent device (10), the packet signal output from the boat (9a) is input to the boat (5b) of the previous device (10) via the boat (3a) and the cable (30), and the packet signal is input to the boat (5b) of the previous device (10). is fed back to the controller (100) via.

That is, when a packet signal is output from the controller (100), it is temporarily stored in the buffer (9B) of each microcomputer (9), and if necessary, predetermined processing is performed by the CPU (9A). and later equipment (10
), and the packet signal that has been transmitted to the final stage is fed back to the controller (100) again.

Therefore, all the equipment can be installed just by performing predetermined operations with the controller (100)! A packet signal is transmitted to the device (10), and the device (10) adjusts the VV according to the packet signal as necessary.
T RB (700) performs control such as operating the video camera (900).

The system in this embodiment is configured as described above. Next, a method of setting addresses for each controlled device will be explained.

In this example, we will explain the case where no address is set in the initial state. For example, if the address of the television (300) is known on the controller (100) side, a command (packet signal ) may also be sent.

As can be understood from Fig. 3, the command (address setting signal) is a command (broadcast; B, C,) in which the command is sent to all controlled devices (area (
A)) has contents for the device (10) to set its address to the value n (area (C)) (area (B)).

Furthermore, when the device (10) sets its own address to the value n, a process is performed in which the contents of the area (C) are set to the value (n+N) and the command is transferred to the next controlled device (
(predetermined processing).

Therefore, n=1. If N=1, TV (300)
, V T RA (500), V T RB
(700) and the video camera (900) sequentially address address 1. Address 2. Address 3. Set to address 4.

In this case, the device W (10) of the video camera (900) sends back a command to set the address to the value 5 to the controller (100). Number of control devices (
value 5 - value 1 - value 4).

In addition, if all controlled devices have the same address in the initial state, specify that address instead of using a broadcast command (that is, use the contents of area (A) as the address value). Just send the command.

As explained below, in this embodiment, the controller (100
) to the television (300), and then the device (10) sequentially sets each controlled device to a different address, making address setting extremely easy.

Next, a method of setting an address such that the address of the k-th controlled device is the value n will be explained.

In this embodiment, addresses are not set for controlled devices that do not require address settings, so this is convenient, for example, when it is desired to control the television (300) and VTR (500) for the time being.

In this case, as understood from Figure 4, the command is
Number (kl) corresponding to the specified controlled device (area D
)have.

In addition, each device (10) interprets it as a command sent to itself when the content of area (D) is (direct 0), and if the value is not 0, it changes the content of area (D) to a value. (-1) is added to the area (D) and is transferred to the next controlled device.

Therefore, when the transfer is performed (k-1) times, the desired controlled device f (kth) is specified, and the address of the controlled device is set to the value n.

In addition, since the controlled device for which an address has been set notifies the controller (100), it is possible to confirm the address setting and to check for controlled devices for which no address has been set. In the setting method, address setting is performed a number of times corresponding to the number of controlled devices.

As explained above, in this embodiment, the controller (1
Since a desired controlled device is set to a desired address by simply sending a command from 00), the setting operation is easy.

In the above two embodiments, the content of the processing performed by the device (10) (such as how to change the address value n) can be set on the controller (100) side, so that various addresses can be changed. You can configure the settings.

Further, as the controller (100), the device t
It is also possible to use (10).

〔Effect of the invention〕

As can be understood from the above explanation, in the address setting method according to the present invention, when an address setting signal is given from the control device to a desired controlled device, the controlled device and subsequent controlled devices set the address. Predetermined processing is sequentially performed on the setting signal.

Therefore, for the predetermined processing performed by each controlled device,
By introducing the process of setting a unique address for each controlled device, each controlled device will have a different address.

In other words, addresses can be set by simply operating the control device.
