Abstract

PURPOSE:To reduce remarkably signal transmission at multi-address by providing a data setting a group simultaneous mode, neglecting a low-order n-bit of an address data at the setting of the group simultaneous mode setting and applying multiple access to terminal devices having address of the neglected low-order n-bit. CONSTITUTION:Assuming that 256 addresses are shared as addresses for each terminal device 2, then an 8-bit address data AD is provided, the low-order 4-bit of the address data AD is neglected in such a case to access the terminal device 2 at the group simultaneous mode, then the addresses are divided into 16 groups at 16 addresses each shown in figure, and in sending a signal to all the terminal devices 2, 16 times of signal transmission are applied. Thus, the group simultaneous mode is provided as one of operating modes MD and at the setting of the group simultaneous mode, the low-order 4-bit of the address data AD is neglected and the address is accessed to apply group simultaneous call.

[Detailed Description of the Invention] [Technical Field] The present invention relates to a multiplex transmission system in which a main device and a plurality of terminal devices are connected in a common transmission-like manner, and which improves the signal transmission format. Generally, a multiplex transmission device f2iVi is configured to perform multiplex transmission using a system configuration as shown in FIGS. 3 to 5. Figure 3 shows the schematic configuration of the entire system.
It is constructed by connecting one main device (1) and a plurality of terminal devices (2) to a common transmission like (3). Main device (1
), a signal in the format shown in Fig. 4 is output cyclically, and the first to nth terminals (2) are sequentially accessed. It is shown in FIG. Here, the format of the transmission signal shown in FIG. 4 is configured as follows. Address data (AD) is a code to identify each terminal device (2), and only the terminal device (2) whose address data code matches its own address code will receive the data from the terminal device (2). It seems like it should stop. The operation mode (MD) defines the type of the data section that follows, and the data (MD) is determined by the value of this operation mode (MD).
DA) is used to switch between a signal for controlling a load such as a relay, and a signal for changing one mode by the operation of a terminal. The data length (BC) is the data that follows (
This is a signal indicating the length of D A), and Bc is an abbreviation for byte length. Error detection code (FCC) is a signal for detecting transmission errors in transmitted signals.
For example, a checksum code is used.

Thus, in a multiplex transmission apparatus having the above-mentioned configuration, cases may arise where it is desired to transmit exactly the same data to a large number of terminals (2). In other words, when it becomes necessary to change the operating mode on the system, or when it becomes necessary to set or reset the crime prevention state in the security system, the same data is sent to a large number of terminal devices (2). The need arises. However, in the conventional example described above, each terminal (2) is
Since the configuration is such that the same data is sent to each terminal device (2) individually, the signal transmission in the format of the conventional example shown in Fig. 3 is performed to each terminal device (2). There was a problem in that it took too much time to send in all the necessary terminal devices (2) IC4-2 because it had to be repeated.

The present invention provides data for setting a group simultaneous e-address for broadcasting to a plurality of terminals in the data sent from the main device, and when setting this group simultaneous e-address, the lower n of address data is provided. By ignoring bits and making it possible to broadcast to terminals with the ignored lower n-bit addresses, it is possible to simultaneously transmit the same information to multiple terminals configured with higher-order addresses. It is possible to greatly shorten the signal transmission during broadcasting, and by providing 2n bits of bit data, '1''1 of this bit data can be
By determining the address of the terminal device with the lower n bits ignored above, the terminal device in the group set for broadcasting can be arbitrarily selected and controlled or not controlled. The purpose of this invention is to provide a multiplex transmission system that makes it possible to perform multiple transmission.

The present invention has the overall configuration as shown in FIG. 3, and is similar to the prior art example in that it normally accesses the cyclic terminal device (2) as shown in FIG. However, the difference is that the signal transmission format in Figure 4 has been changed as shown in Figure 1, and the address structure for each terminal (2) is divided into groups as shown in Figure 2. are doing. First, the grouping of addresses in FIG. 2 will be explained. Assuming that 256 addresses are allocated as addresses for terminal device (2) this winter, it will have 8-bit address data (AD), but at this time, the lower 4 bits of address data (AD) will be ignored. If terminal device (2) is accessed in group simultaneous mode, it can be divided into 16 addresses each having 16 addresses as shown in Fig. 2. Therefore, all terminal devices (2) K Even when performing signal transmission on the other hand, it is possible to perform signal transmission 16 times.

Furthermore, in this embodiment, as shown in FIG. 1, bit pattern data indicating a bit pattern in the case of group simultaneous calling is added, and in this embodiment, address data (AD) is
Since the lower 4 bits of the data are ignored, 16 bits and 2' = 16 bits of bit pattern data are added per group. That is, the bit pattern data has 16 bits corresponding to the number of terminal addresses in the group for simultaneous calling specified by the address data (AD) and E-do data (MD), and each bit corresponds to the respective address VC1. There is a one-to-one correspondence, and when address data (AD) is set to 16 in Figure 1, a group of 16 channels (1
6 to 31), only the +6 and +9.30 channels are not controlled, and the remaining terminals are controlled all at once, and the bit position of the channel to be controlled is set to "l". Only the terminal device (2) of the channel of this '1' signal receives the data signal (DA).

Since the present invention is configured as described above, it is possible to simultaneously send a broadcast signal to a plurality of terminals specified by the upper bits of the address data when a group is broadcast simultaneously, and Data transmission to each terminal device can be carried out all at once, greatly reducing the time required for signal transmission.Furthermore, bit pattern data can be used to individually select and control each terminal device within a group. This has the effect that control can be determined, and that it is possible to perform control similar to fine-grained individual control rather than using a simultaneous control method.
