Abstract

PURPOSE:To provide a remote controller which can be used in common to equipment with different specifications. CONSTITUTION:The remote controller 1 is provided with all the functions in a storage part 3 in advance so as to be used for plural different equipment. A main controller 5 transmits information including the function selection signal of a storage part 6 via a signal transmission line 8 from a transmission/reception circuit 7 to make the remote controller 1 select the function required for its own specification. Such information is received by the transmission/reception circuit 4 of the remote controller 1, and the function required for the main controller 5 can be selected by deciding and storing the function selection signal in the information by a judging part 2. Thereby, it is possible to eliminate burden on time and expenses such as the development of the remote controller at every mass production of main body equipment, and also, to eliminate complexity on maintenance management including a manufacturing process and a market.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller which can be commonly used for devices having different specifications and a transmission system for selecting its function.

[0002]

2. Description of the Related Art Conventionally, a main unit and a remote controller for remotely controlling the main unit have a 1: 1 relationship in principle, and a similar remote unit having a different specification had to use a remote controller having a different specification. .. Further, the transmission information from the main control unit to the remote controller is as shown in FIG. 5, and each information is only the input / output information which changes from time to time due to the operation of the equipment.

[0003]

However, in such a conventional example, even remote controllers having similar input / output specifications cannot be standardized because the operation specifications of the main body devices are different, so that the remote controller cannot be shared. There are problems that the number of types increases and management becomes complicated, and that costs are incurred each time the remote controller is developed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. A remote controller having a similar input / output specification is used in common, and transmission from the main control device to the remote controller is performed. It is an object of the present invention to solve the above problems by including function selection information other than input / output in the information and allowing the function of the remote controller to be initially selected within a fixed time from the start of transmission.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention.
First, the configuration will be described. For the purpose of being commonly used by a plurality of devices, a transmission / reception circuit 4 for transmitting, a remote controller 1 having a determination unit 2 and a storage unit 3 for determining and confirming transmission information, and a remote controller 1. A transmission / reception circuit 7 for transmitting a function selection signal, a main control unit 5 having a transmission information storage unit 6, and a signal transmission line 8 for transmission of both the remote controller 1 and the main control unit 5.

FIG. 2 shows an example of transmission information from the main controller 5 to the remote controller 1. In addition to the conventional input / output information, a function selection signal is provided (the order of other signals is not related), and the function of the remote controller 1 can be changed by a combination of "1" or "0" of these signals. Select. In the case of FIG. 2, since there are three types of selection signals, c, d, and e, there are 2 × types.
Up to 2 × 2 = 8 functions can be selected.

Further, FIG. 3 shows another example of transmission information for function selection. This is because there are many types of function selection, and when the signal cannot be sent together with the normal input / output information, the main controller 5
This is a system in which only the function selection signal is sent at the start of transmission from the remote controller 1 to the remote controller 1, and the normal input / output information is sent after a fixed time or after receiving the selection confirmation signal from the remote controller 1.

[0008]

[Operation] Next, the operation will be described. As shown in FIG. 1, the remote controller 1 is provided with all the functions in the storage unit 3 in advance so that it can be used for a plurality of different devices. On the other hand, the main controller 5 transmits information including a function selection signal shown in FIG. 2 or FIG. 3 from the transmission / reception circuit 7 via the signal transmission line 8 in order to make the remote controller 1 select a function required for its own specifications. To do.

In principle, the transmission of this information is performed from the beginning of the transmission because it is necessary to select the function of the remote controller 1 with the highest priority. Next, the remote controller 1 receives the information sent through the signal transmission line 8 by the transmission / reception circuit 4, and the function selection signal in the information is judged by the judgment unit 2 and stored therein, whereby the function required for the main controller 5 is obtained. Select.

FIG. 4 shows an example of the function judgment of the remote controller by the function selection signal. This is an example of using three types of signals in FIG. 2, and eight types of function selection from mode m to mode t are possible. When the main controller 5 wants the remote controller 1 to select the function of mode q, the selection signals “1” and “0” are selected.
The signal of "0" should be sent.

[0011]

As described above, according to the present invention, the function is selected within a certain period of time before the start of regular transmission between the remote controller and the main control unit, which have the functions required for a plurality of different devices in advance. Since the target function is selected initially according to the information, the remote controller can be versatile, and the time and cost burden of developing the remote controller each time the main unit is mass-produced can be saved and the remote controller can be manufactured. The effect is that the complexity of maintenance management including the stage and the market can be eliminated.
