PROBLEM TO BE SOLVED: To reduce information transmission quantity by stopping transmission to a slave station judged not to require control data based on reply data and sending same data and address to slave stations whose reply data are the same. SOLUTION: A master station 1 sends same control data D10 to all slave stations 1, 2,...n and each of the slave stations 1, 2,...n receives the same control data D10 and process them and sends an address A1j to the master station as reply data. The master station 1 receives the address A1j and processes it and sends the address A1j and data D1j for control to other slave stations than the slave station whose address is A10 The master station 1 receives the reply address A1j from each of the slave stations 1, 2,...n and sends the control address and data to the received address A1j till reply data except the address A10 are not in existence. The information quantity to be sent is reduced by sending the same data and address to the slave stations.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a master station, a master station and a master station.
Regarding the remote control method in the system composed of a plurality of slave stations each having one load connected through the transmission line of the book, in particular, the master station sends the same control data to each slave station, Alternatively, when an address, which is the same response data for multiple slave stations, is received from each slave station, multiple slave stations are simultaneously controlled by the same address by sending control data consisting of the address and data to the slave station group. The present invention relates to a simultaneous control method for a plurality of slave stations of a remote control system.

In a remote control system, when the load connected to each slave station is controlled according to the control of the master station,
It is required that the load be controlled as fast as possible and that the master station control the load with as little information as possible.

For this reason, conventionally, the master station judges from the response data received from each slave station in a time division manner, and the control data indicating a method for controlling the load is transmitted to each slave station in a time division manner. Although a method is provided, it takes time to change the operation method of the load and the amount of data, that is, the amount of information, transmitted from the master station to the slave station group is large, so the slave station can be sent as fast as possible from the master station. It is necessary to control with as little information as possible.

The same operation as above from 00 is repeated.

However, the master station (1) has all the slave stations 1,
2, ..., l, ..., n (21,22, ..., 2l, ..., 2
If n) is controlled with respect to the same control target event, the same control area is transmitted to all the slave stations having the same response data, and the same control data is transmitted.
Even for the slave station that is determined from the response data that the control data is unnecessary, the transmission area on the transmission frame is taken and transmitted.

[0012]

Therefore, the master station (1)
, All slave stations 1, 2, ..., L, ..., n (21, 2,
2, ..., 2l, ..., 2n) for the same controlled event, all slave stations having the same response data have the same transmission area on the transmission frame and the same control data. Therefore, there is a problem in that the same control data will be transmitted many times.

Further, even for the slave station judged from the response data that the control data is unnecessary, since the transmission area on the transmission frame is taken and transmitted, there is a problem that an unnecessary transmission area is required.

The present invention is intended to solve such a problem of the prior art, and one transmission area is taken on a transmission frame for all the slave stations having the same response data. Control data is transmitted, and from the master station (1), slave stations 1, 2, ..., 1, n, (21, 22, ..., 2l,
,, 2n) to reduce the amount of information to be transmitted,
For the slave station that is determined to be unnecessary control data from the response data, by transmitting without transmitting the transmission area on the transmission frame, the information transmission amount is reduced, and by reducing the information transmission amount, It is an object of the present invention to provide a remote control system capable of controlling a load as fast as possible.

Send control data consisting of address and data.

Therefore, in the case of the first aspect of the present invention,
In the transmission frame having the frame structure of the conventional example, the master station has all the slave stations 1, 2, ..., 1, ..., N (21, 22, 22).
, 2l, ..., 2n), compared to the case where control data is constantly transmitted in a time-division manner, from the master station (1) to the slave station 1,
2, ..., l, ..., n (21,22, ..., 2l, ..., 2
It is possible to reduce the amount of information transmission to be transmitted in n).

In the second mode of the present invention, the master station receives the address A _oo , which is the response data, from one or more slave stations which are judged to be unnecessary for the next control data. Address A _oo, which is this response data, is the slave station 1 of the master station (1).
2, ..., l, ..., n (21,22, ..., 2l, ..., 2
Even if the control target event for n) is changed, the same value is obtained.

, 2l, ..., 2n), each time the controlled object event is changed, the following control data is received from one or more slave stations which are determined to be unnecessary, and different addresses as response data are received. Then, the master station (1) becomes the slave stations 1, 2, ..., 1,
, N (21,22, ..., 2l, ..., 2n), the number of addresses received as response data from one or more slave stations that are determined to be unnecessary for the next control data is small. I'm sorry.

As described above, in the case of the second mode of the present invention, as compared with the case of the first mode of the present invention, the one or more slave stations for which the following control data is determined to be unnecessary Therefore, the number of addresses received as response data can be small, so
The number of addresses to be stored in the memory of the master station (1) can be small, which can reduce the memory usage. Therefore, the circuit configuration of the master station (1) can be simplified.

In the third mode of the present invention, the master station transmits control data only to slave stations other than the address A _io . This is because the master station (1) transmits the address and data for control only to the slave stations other than the address A _io in the first embodiment of the present invention. 2, ..., l, ..., n (21,22, ..., 2l,
, 2n), the transmission area of the control data to be transmitted is reduced by the address for control, so that the information transmission amount can be reduced.

In the fourth mode of the present invention, the master station transmits one address for control and one or more data corresponding to one or more addresses to slave stations other than the address A _io . This is because the master station (1) transmits the address and data for control only to the slave stations other than the address A _io in the first embodiment of the present invention. 2, ..., l, ..., n (21,22, ..., 2l,
, 2n), the transmission area of the control data to be transmitted is reduced by one address for control and the other addresses for control, so that the information transmission amount can be reduced.
