受信することを特徴とする。The selective broadcast communication method of the present invention is a system in which a plurality of data transmitting/receiving devices are connected to a bus, and data is broadcasted and received among the data transmitting/receiving devices and data is transmitted/received to a designated data transmitting/receiving device through the bus as a whole. The data transmitting/receiving device on the sending side assigns an identification number to the transmission request data,
After each data transmitting/receiving device transmits a list of identification numbers of the transmission request data required by each data transmitting/receiving device to all data transmitting/receiving devices other than this transmitting data transmitting/receiving device, the transmitting data transmitting/receiving device broadcasts the transmission request data. send,
The receiving side data transmitting/receiving device is characterized in that it selectively receives only data that matches the identification number of the transmission request data that has been received in advance.
〔実施例〕 次に、本発明について図面を参照して説明する。〔Example〕 Next, the present invention will be explained with reference to the drawings.

。In the system of this embodiment, the data transmitting/receiving devices 1 and 2 are connected to the bus 9.
It becomes combined with. The data transmitting/receiving device 1 classifies the transmission request data 3 into destination data transmitting/receiving devices, assigns identification information numbers 4, 5, and 6, and creates an identification information management table 7 having identification information of transmission data for each data transmitting/receiving device. The identification information management table group 8 is created by collecting the information.

る。Next, the operation of this embodiment will be explained. When a request to transmit data 3 is generated, the data transmitting/receiving device 1 obtains the identification information management table 7 corresponding to the data transmitting/receiving device to be transmitted from the identification information management table group 8, and sends it to all the data transmitting/receiving devices via the bus 9. The identification information management table 7 corresponding to is transmitted. Transmission target data transmitting/receiving device 2
The corresponding identification information management table 7 is received and stored. Next, the data transmitting/receiving device 1 divides the data 3 into units of identification information, adds the identification information, and performs a circular transmission. In the data transmitting/receiving device 2, if the received identification information number is 4 or 6 as shown in FIG. If the identification information number is 5, it does not exist when compared with the identification information management table 7, so no data is imported. In this way, in this embodiment, only the data corresponding to identification information numbers 4 and 6 are captured.
以上説明したように本発明は、データの識別情報をあら

より、同一データを複数回送信する必要がなくなるので
、データ送信時間を短縮できる効果がある。As described above, the present invention has the effect of shortening the data transmission time because it is not necessary to transmit the same data multiple times by transmitting data identification information to the transmission target data transmitting/receiving device in advance.
