Abstract

PURPOSE:To control plural terminal equipments simultaneously by outputting the command signal to a device control without giving an acknowledge reply when a destination address of a command signal is coincident with an address set to a detect ion address setting section. CONSTITUTION:An operation stop command packet sent to a destination except its own address is received by a detection address setting section 28 as a packet addressed to its own address, then the address corresponding to the address of other terminal equipment interface device is set. When the operation stop command packet is received, the communication control section 22 discriminates whether or not the destination address is coincident with the address set to its own address setting section 23 and in the case of dissidence, the address is compared with an address set to the detection address setting section 28, and when they are coincident, only the operation stop command signal is outputted to the device control section 25 without immediate acknowledge reply. Thus, plural terminal equipments are operated by having only to output the operation stop command signal from a remote controller to one terminal equipment interface device.

In order to operate and stop a plurality of devices 4 at the same time, it is necessary to output operation and stop instruction signals to each terminal device interface device 5, which poses the problem of cumbersome operation.

The present invention solves the above problems, and provides -1 terminals.
It is an object of the present invention to provide a terminal device interface device that makes it possible to operate a plurality of terminal devices simply by outputting No. 43 of a run/stop instruction to the device interface device.

Above 5 ways to solve the problem! In order to solve the problem, the present invention provides a plurality of terminal device interface devices connected to a common bus, which includes a self-address setting section that sets an address value for self-identification, and a terminal device n having a different address value. In order to receive an instruction signal sent to the device interface device as an instruction signal addressed to its own address, the terminal includes a detection address setting section that sets a detection address value corresponding to the other address value, and a terminal that controls the device. The equipment control unit that exchanges signals for output and monitor input, and when receiving an instruction signal addressed to its own address, performs an i-acknowledgement response, and when receiving an instruction signal addressed to a detection address, does not perform an acknowledgment response and performs the above-mentioned procedure. and a communication control section that outputs an instruction signal to the device control section.

Effect With the above configuration, when the communication control unit receives an instruction (No. 8 and the destination address matches the address set in the detection address setting unit), it sends an instruction signal to the device control unit without issuing an acknowledgment to the destination. Therefore, without causing any harm to the transmission of other terminal equipment interface devices connected to the common bus, the instruction signal to other terminal equipment interface devices having the detection address as their own address can be sent to the own address. It can be received as an instruction signal to the destination.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings. Note that the same components as those in FIG. 2 of the conventional example are designated by the same reference numerals, and description thereof will be omitted.

FIG. 1 is a block diagram of a terminal grip interface 菰jN showing one embodiment of the present invention. In FIG. 1, the bar reception circuit section 21 is connected to the home bus 3 of the common bus system via the information outlet 2, and modulates the signal transmitted from the communication control section 22 and outputs it to the home bus 3. The signal transmitted via the home bus 3 is demodulated and output to the communication control section 22. self? The dress setting section 23 consists of an 8-pit dip switch, and the communication ffdJ 61
The first unit 22 sets its own address for packet exchange of information via the home bus 3. The monitor input circuit section 24 receives a monitor signal) from the terminal 4 which is input from the gland 7.
The state of lightning is detected at the lightning E level and output as a monitor signal to the equipment control section 25. The control output circuit unit 26 outputs a pulse signal to the control output FA6 to control whether the terminal device 4 is operating or stopping! control to the target. The key force detection unit 27 constantly monitors the key force and outputs an operation/stop instruction signal to the device control unit 25 when the iJ3 key is pressed.

The detection address setting unit 28 receives operation/stop instruction packets sent from the 8-bit burp switch to destinations other than the own address as packets addressed to the own address, so that the detection address setting unit 28 receives the operation/stop instruction packets sent to destinations other than the own address as packets addressed to the own address. Set the address value corresponding to the address value. Communication control unit 2
2 decodes received packets, assembles packets to be transmitted, and transmits and receives signals with the communication control unit 22 of the other terminal equipment interface H1ff in a procedure of packet transmission and reception and its M1 acknowledgment. Further, when the communication control unit 22 receives a packet for operation or stop instruction, it first determines whether the destination address matches the address set in the self-address setting unit 23, and if they match, ! [Sends the response and operates the one-unit control unit 25,
Outputs a stop instruction signal. If it does not match the own address, then compare it with the address set in the detection address setting section 28 with ¥Qf"i:5. If it matches, the device control section 25 will start or stop the operation without responding. It outputs only the instruction signal.Also, the status monitor signal of the terminal device 4 inputted from the device control section 25 is assembled into a packet and transmitted.

In this way, it is possible to receive not only operation and stop instruction signals addressed to the self-address, but also operation and stop instruction signals addressed to the address set in the detection address setting section 28 as instruction signals addressed to the self-address.

Therefore, it is only necessary to output a run/stop instruction signal from the remote control bag Wt1 to one terminal device interface device.
It becomes possible to operate multiple terminal devices.

Effects of the Invention As described above, according to the terminal device interface device of the present invention, an instruction signal addressed to the address set in the detection address setting section can be received as an instruction signal q addressed to the own address. It is possible to perform the same operation as an instruction sent to another terminal device interface having the address set in the detection address setting section. Therefore, by sending an instruction signal from the remote control device to one terminal device-r interface device, multiple terminal devices can be connected to 1111.
