[Detailed description of the invention]

Industrial Application Field The present invention connects a plurality of control signal generating devices and a plurality of terminal devices that can communicate with each other on the same transmission channel, and transmits data from the control signal generating device to the transmission channel. The present invention relates to a transmission control device that controls the terminal device using signals. Configuration of a conventional example and its problems Figure 1 shows the configuration of a conventional example of a home automation system, in which 1 is a terminal which is a control signal generating device, modules 2, 3, 4 which are a plurality of terminal devices, They are connected via a transmission communication path 5. Loads 6, 7, and 8 are connected to each of the modules 2, 3, and 4, respectively, and the signals generated by the terminal 1 are transmitted to each of the modules 2, 3, and 4 through a transmission communication path 5. The loads 6, 7, and 8 are controlled by transmitting the signals. In this system, the state of each module 2, 3, and 4 is preset to one state when the power is restored from a power outage, and it has the drawback that the state when the power is restored from a power outage cannot be arbitrarily selected. . Each module 2 when power is restored from a power outage,
Control modes 3 and 4 include one that maintains the state of the load before the power outage and returns, and one that returns with the load in a non-conducting state to ensure safety. In this method, one or the other was selected in advance, and it was not possible to arbitrarily select one of them. In addition, each module 2 when the power is restored from a power outage,
The operating modes of 3 and 4 are the loads 6, 7, and 8 before the power outage.
Depending on the type of load, it may lead to a fire or other danger, especially if a power outage occurs while you are out. There was a safety issue. On the other hand, if the operating mode of each module 2, 3, 4 is set to make the loads 6, 7, 8 non-conductive when the power is restored from a power outage, the following problem occurs. In other words, safety can be ensured when the power is restored after a power outage, but it is not dangerous in the case of a short power outage or if the connected loads 6, 7, and 8 are in a conductive state when the power is restored from a power outage. This was inconvenient because it did not maintain the load state before the power outage. OBJECTS OF THE INVENTION In view of the above drawbacks of the present invention, it is an object of the present invention to provide a transmission control device having means for arbitrarily selecting the operation mode of each module when the power is restored from a power outage. Structure of the Invention To achieve this object, the transmission control device of the present invention provides a state selection means that can arbitrarily select whether or not to output a simultaneous control signal that controls all terminal devices at the same time when power is restored from a power outage. A control signal generating device that has a function to restore the connected devices to the state before the power outage when the power returns from a power outage, and a function that receives the simultaneous control signal sent by the control signal generator when the power returns from a power outage. a plurality of terminal devices each having operation selection means for arbitrarily selecting whether or not to operate a load in accordance with the control signal; and a transmission communication path that connects the control signal generating device and the terminal device to each other. It consists of DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows the configuration of a transmission control device for a home automation system in an embodiment of the present invention. In Figure 2, 9
is a terminal which is a control signal generating device, 10,1
1 and 12 are terminal devices that are remotely controlled by signals from terminal 9; 13 and 1 are modules;
4 and 15 are loads that are connected to the modules 10, 11, and 12 and are remotely controlled. Terminal 9 has a control signal output circuit 16 and a transmission circuit 17
and a power outage detection device 18 that detects the occurrence of a power outage, and each module 10, 11, when the power is restored from a power outage.
It is equipped with a state selection switch 19 (hereinafter referred to as state selection means) at the time of power restoration, which is a selection means that can arbitrarily select whether or not to output a simultaneous control command to 12. It is connected to a certain electric light line 24. Note that a plurality of terminals 9 may be provided so that they can communicate with each other. The module 10 includes a communication means 20 and a calculation means 2.
1, when the latching relay 22 and the terminal 9, which return the load 13 to the state before the power outage when the power is restored from a power outage, transmit a simultaneous control signal, whether or not to operate the load 13 in accordance with this control signal; That is, it is comprised of an operation selection switch 23 (hereinafter referred to as operation selection means) which is selection means for arbitrarily selecting whether or not to accept a simultaneous control signal. Moreover, the modules 11 and 12 also have a similar configuration. 24 is terminal 9 and module 1
This is a power line that is a transmission communication path connecting 0, 11, and 12. The operation of the transmission control device configured as described above will be explained below. First, the terminal 9 is connected to each module 10, 11, 12 via a power line 24, and a control signal generated by a control signal output circuit 16 is sent to the modules 10, 11, 12 via a power line 24 by a transmitting circuit 17. Output for 12. Modules 10, 11, 12 receive this control signal via communication means 20. At this time, the calculation control means 21 selects the operation selection means 2.
3, and if it is open, the latching relay 22 is controlled to close the loads 13, 14, 15.
is controlled according to the contents of the control signal, and if it is in the closed state, the contents of the control signal are ignored. Load 1 connected to modules 10, 11, 12 in this way
3, 14, and 15 are controlled to be in an ON state or an OFF state. Here, the operation when a power outage occurs will be explained. When a power outage occurs, the modules 10, 11, and 12 are brought into a non-voltage state by the latching relay 22 while maintaining the states of the loads 13, 14, and 15 before the power outage, respectively. Then, the power failure detection device 18 in the terminal 9 detects a power outage state of the power line 24,
A control signal is sent to the control signal output circuit 16 when the power is restored from a power outage. In response to this signal, the control signal output circuit 16 generates a simultaneous control signal containing a simultaneous non-conducting command to make all loads non-conductive at once. This simultaneous control signal is sent to the transmitting circuit 17.
The signal is sent from the terminal 9 to each module 10, 11, 12 via the power line 24.
Here, whether or not to send out the simultaneous control signal from the terminal 9 can be arbitrarily selected by switching the state selection means 19. In other words, when you want to send a simultaneous control signal to each module, leave it open, and when you do not want to send it, leave it closed. Each module 10, 11, 12 transmits the simultaneous control signal to the communication means 20 of each module 10, 11, 12.
is received, and the arithmetic control means 21 operates the latching relay 22 to detect the connected loads 13,1.
4 and 15 are controlled so that they are in a non-conductive state. Here, for example, whether or not the module 10 accepts this simultaneous control signal can be arbitrarily selected by setting the operation selection means 23 of the module 10 to open or close. That is, when the simultaneous control signal is to be accepted, the operation selection means is set to open, and when the simultaneous control signal is not to be accepted, it is set to closed. The same applies to the module 11 and the module 12. An example of the use of the transmission control device operating as described above will be described with reference to the table. Each module 10,1
Loads 13, 14, 15 connected to 1, 12
is dangerous if it remains ON when the power is restored from a power outage, or when the loads 13, 14, and 15 are
If there is a safety problem if it is in the ON state,
The state selection means 19 is opened and set to transmit a simultaneous control signal. At the same time, each module 1
The settings of the operation selection means 23 of 0, 11, and 12 are also set by the latching relay 22 upon receiving this simultaneous control command.
The arithmetic control means 21 is set to be open so that the arithmetic control means 21 operates to bring the circuit into a non-conducting state. In this way, when the power is restored from a power outage, the loads 13, 14, 15 connected to each module 10, 11, 12 can be turned off, thereby ensuring safety. On the other hand, if a load is connected to each module 10, 11, 12 that is not dangerous even if it is ON when the power is restored, or when the power is restored after a short power outage, the load state before the power outage may be restored. If desired, by setting the state selection means 19 to close so that the simultaneous control signal is not transmitted from the terminal 9, the loads 13, 14, and 15 can be recovered from the power outage in the load state before the power outage. . In addition, when the power is restored, the loads 13, 14, and 15 connected to each module 10, 11, and 12
If the ON state includes both dangerous and non-hazardous items, the state selection means 19 should be opened to open the setting of the operation selection means for the module connected to the load that is dangerous if the ON state is restored when the power is restored. By setting the operation selection means of modules connected to loads that are not dangerous even if they are in the ON state when the power is restored, each module 10, 1
When the power is restored, the loads can be restored in a state that is compatible with the safety of the loads 13, 14, and 15 connected to the power supplies 1 and 12. As described above, according to this embodiment, the state selection means 19 and the operation selection means 23 are arbitrarily switched and combined in various ways to adapt to the usage load, and to supply power from a power outage in a state adapted to the conditions of use. Each load can be restored at the time of restoration, and safety is also ensured.

[Table] “Dangerous load” and “safe load” are
Indicates when it is in the ON state. In this embodiment, a power line is used as a transmission communication path connecting the terminal 9 and each module 10, 11, 12, but a dedicated transmission communication path may be provided separately from the power line. Further, in this embodiment, the state selection means 19 is set so that the simultaneous control signal is transmitted when the state selection means 19 is open, but it may be set in the opposite manner. Similarly, the setting of the operation selection means may be reversed to that of the embodiment, and may be closed when it is desired to receive a simultaneous control signal. Effects of the Invention As described above, the present invention provides a control signal generating device having a state selection means that can arbitrarily select whether or not to output a simultaneous control signal containing a simultaneous disconnection command when the power is restored from a power outage; By having a plurality of terminal devices that have operation selection means that can arbitrarily select whether or not to accept this simultaneous control signal, it is possible to recover the load from a power outage in a load state that is appropriate to the load and conditions of use. It can improve usability and at the same time ensure safety, and its effects are great.
