For example, each of switches 210 and 211 is a two-state toggle switch. The transceiver 22 has both a transmitter and a receiver, and is configured to transmit and receive signals by wire or wireless communication. In the example of Fig. 2, the transceiver 22 is a wired device connected to the communication line Ls. The storage device 23 stores information (data) used by the controller 20, and the information includes an identification code for operating the terminal 2 and an identification code of at least one operation control terminal associated with the operation terminal 2, wherein the operation terminal 2 is the operation switch 210. . That is, the storage device 23 stores a correspondence (for example, a table) between an operation input (signal) from the operation switch 210 and an identification code of at least one operation control terminal in addition to the identification code of the operation terminal and the like. However, not limited thereto, the identification code of the operation terminal of the present invention may be a code (for example, a MAC address) held by the transceiver 22.

In the embodiment, in response to the operation input of the control mode 211, the controller 20 sets the control mode of the controller 20 to the operation mode or the registration mode. Similarly, in response to the operation input (or the operation input from the operation switch 210), the controller 20 generates a mode setting command for setting at least each control mode of the controller of the operation control terminal 1 to an operation mode or a registration mode. . The controller 20 then transmits at least the mode setting command to at least each of the operational control terminals 1 via the transceiver 22.

The control mode of the device 20 is the registration mode. The controller 20 also generates a mode setting command for setting each control mode of the controller of the operation control terminal 1 to the registration mode.

At the operation control terminal 1, each controller 10 sets its own control mode to the registration mode in accordance with a mode setting command from the corresponding transceiver 12 (its own transceiver). Thereby, each control mode of the controller of the terminal is set to the registration mode. In the registration mode, if an operation control input longer than the time threshold for registration is obtained from the operation control switch 110, any controller 10 transmits the identification code through the transceiver 12.

At the operation terminal 2, if the identification code of at least one operation control terminal is received from the transceiver 22, the controller 20 associates the identification code to the operation switch 210 to store the associated identification code in the storage device 23. Accordingly, one or more required operational control terminals can be associated to the operational switch 210. Therefore, if another mode setting command for setting to the operation mode is obtained through the control mode switch 211, the control mode of each controller is set to the operation mode.

First practical example

Figure 3 shows a practical example of the present invention. In this example, the load control system is formed by a plurality of operation control terminals 1 (four or more in FIG. 3) and a plurality of operation terminals 2 (two or more in FIG. 3), wherein Each of the operation control terminals 1 is connected to a load 17, and the operation terminal 2 is connected to the operation control terminal 1 through the signal line Ls of the two-wire system. For example, each load 17 is a light-emitting load and is connected to a commercial AC power source (AC) via a wire Lp. However, not limited thereto, for example, the load of the present invention may be an electric device such as an air conditioner, a fan, an electric curtain, or the like.

The operation control terminal 1 includes three different terminals, that is, an operation control terminal 1A, an operation control terminal 1B, and an operation control terminal 1C (or 1D). The terminal 1A has an operation control switch (110) S11 and has a function of turning the load 17 on and off in response to an operation control input from the switch S11 (referred to herein as "individual on/off function"). The terminal 1B has operation control switches (110) S21 and S22, and individually responds to the operation control inputs from the operation control switches S21 and S22 to turn on and off the individual (two) loads 17 for individual on/off functions. The operation control terminal (1C) or (or 1D) has operation control switches (110) S31-S33 (or S41-S43), and each has an operation control input from the switch S31 (or S41) to be turned on and off. The function of the load 17 (referred to herein as the "lighting/darkening function") and the function of increasing and decreasing the light output of the load 17 in response to operational control inputs from switches S32 and S33 (or S42 and S43).

The operation terminal 2 includes two different terminals. One is an operation terminal 2A having operation switches (210) S51-S53, and the other is an operation terminal 2B having operation switches (210) S61 and S62. The operator terminal also has a function (referred to herein as a "remote control" function) that responds to any operational input of the operational switch and controls any operational control terminal by a packet including control commands transmitted through the signal line Ls. The load of 17.

Each of the operation control terminal 1 and the operation terminal 2 is buried in a wall of the house or the like by a flush plate and a fixing frame of the buried pipeline.

In FIG. 1, the transceiver 12 is configured to transmit the packet encoding and digital modulation of the format of FIG. 4A to transmit the packet through the signal line Ls; and simultaneously receive the packet through the signal line Ls to decode and digitally demodulate the packet. The destination terminal and the source terminal are identified by a unique identification code assigned to each of the operation control terminals 1. The identification code can be a unique physical address that is configured by the hardware manufacturer to the hardware, such as a MAC address, or any address configured by the user or the like. In short, each of the operation control terminal 1 and the operation terminal 2 in the load control system (the same network) must be configured with a unique identification code. The packet to be transmitted includes a preamble for establishing synchronization, a control bit for setting a data, a destination address, a source address, information such as a control command or the like, and for error detection. Check sum. The first practical example uses the multiple transmission method of CSMA/CD.

A console (keypad) 11 monitors an operational control input of an operational control switch 110. The console 11 provides an operational control input (operation control signal) to the controller 10 when the operational control input is obtained. The operational control open relationship consists of a push switch, such as a tact switch or the like, and an operating handle (lid) for pressing the push button switch. The push button switch has a generally open contact point that is open (closed) when the push button switch is not pressed through the operating handle, and is closed (turned on) when the push button switch is pressed through the operating handle. That is, in response to the opening or closing of the operation control switch 110 (S11; S21 or S22; S31, S32 or S33; or S41, S42 or S43), the console 11 provides a corresponding operational control input to the controller 10. In one example, the operational control switch can provide two different operational control inputs to the controller 10. One of the operational control inputs is provided when the operational control switch is pressed for a relatively long period of time, and the other is provided when the operational control switch is pressed for a relatively short period of time.

The controller 10 includes a central processing unit (CPU) and is configured to receive an operational control input from the console 11 to provide a control signal corresponding to the operational control input to the driver 14. The driver 14 is configured to supply or stop supplying energy to the load 17 via a commercial alternating current (AC) power source in response to the control signal. In the case where the operation control terminal 1C (or 1D) has a lighting/darkening function, the driver 14 further adjusts the power per unit time of the power supply (AC) supplied to the load in response to the control signal, thereby increasing or decreasing the light output of the load 17. . The supply of energy to the load 17 can be supplied or stopped using a relay. A semiconductor device such as a triac or the like can be used to adjust the power fed in.

The storage device 13 includes a rewritable non-volatile semiconductor memory (such as EEPROM or flash memory) and stores information such as a multicast address, an identification code, and the like for identifying each load 17 or the like. When the user configures a unique identification code to the operation control terminal 1, the identification code is also re-stored in the storage device 13. The indicator 15 is set to indicate the operational state (lighting or extinguishing) of the load 17. For example, the indicator 15 has a light-emitting device (LD11; LD21 and LD22; LD31; or LD41) such as a light-emitting diode, and a driving circuit for allowing the light-emitting diode according to the control signal of the controller 10. Turn it on or off. As shown in FIG. 3, the light emitting diodes (LD11; LD21 and LD22; LD31; or LD41) are adjacent to the operation control switches (S11; S21 and S22; S31; or S41). The power source 16 is set to convert AC power of the commercial AC power source into DC power to provide DC power to each portion of the operation control terminal 1.

The operation of the operation control terminal 1 will be described below. At the operation control terminal 1A, when the operation control switch S11 is manipulated (pressed), the console 11 (switch S11) supplies an operation control input (operation control signal) to the controller 10. The controller 10 provides a control signal to the driver 14 for inverting the operational state of the load 17 (stops providing energy when the load 17 is illuminated and provides energy to the load 17 when not illuminated). The driver 14 turns the relay on or off in accordance with a control signal from the controller 10 to reverse the operational state of the load 17. After supplying the control signal to the driver 14, the controller 10 provides a control signal to the indicator 15 for inverting the state of the light-emitting device LD11 (turning off the light-emitting device LD11 when it is lit, and starting the light-emitting device when it is not lit) LD11). Thereby, the light-emitting device LD11 is turned on or off by the drive circuit of the indicator 15 by the control signal. At the operation control terminal 1B, when the operation control switch S21 is manipulated (pressed), the operational state of the corresponding load 17 and the state of the corresponding light-emitting device LD 21 are reversed. When the operation control switch S22 is manipulated (pressed), the operational state of the corresponding load 17 and the state of the corresponding light-emitting device LD 22 are reversed.

At the operation control terminal 1C (or 1D), when the operation control switch S31 (S41) is manipulated (pressed), the operational state of the load 17 and the state of the light-emitting device LD 31 (or LD 41) are respectively inverted. When the operation control switch S32 (or S42) is manipulated (pressed) when its corresponding load 17 is illuminated, the controller 10 supplies a control signal to the driver 14 in response to the operation control input from the console 11 to increase the load. 17 light output (dimming level). The driver 14 increases the unit time power fed to the load 17 in accordance with the control signal. If the operation control switch S33 (or S43) is manipulated (pressed) when its corresponding load 17 is illuminated, the controller 10 responds to the operational control input from the console 11 and supplies a control signal to the driver 14 to reduce the load 17 Light output (dimming value). The driver 14 reduces the unit time power fed to the load 17 in accordance with the control signal. In an example, if the operation control switch S32 or S33 (or S42 or S43) is manipulated (pressed) when the corresponding load 17 is not illuminated, the light output of the load 17 will increase or decrease after it is illuminated. . In an example, when the load 17 is not illuminated in response to an operational control input from the operational control switch S31 (or S41), the controller 10 stores the dimming value of the load 17 just before being unlit in the storage device 13. . Therefore, when the operation control switch S31 (or S41) is manipulated, the controller 10 drives the load 17 through the driver 14 in accordance with the dimming value stored in the storage device 13. Thereby, the load 17 is illuminated with the previous dimming value.

In FIG. 2, the transceiver 22 is configured to encode and digitally encode the packet having the format of FIG. 4A to transmit the packet through the signal line Ls; and simultaneously receive the packet through the signal line Ls to decode and digitally demodulate the packet. The destination terminal and the source terminal are identified by a unique identification code assigned to each of the operation control terminals 1.

A console (keypad) 21 monitors an operation input of the operation switch 210. When the operation switch S51, S52 or S53 (or S61 or S62) is manipulated (pressed), the console 21 provides a corresponding operation input (signal) to the controller 20. The operation open relationship consists of a push switch, such as a tact switch or the like, and an operating handle (lid) for pressing the push button switch. The push button switch has a generally open contact point that is open (closed) when the push button switch is not pressed through the operating handle, and is closed (turned on) when the push button switch is pressed through the operating handle. That is, in response to the opening or closing of the operation switch 210 (S51, S51 or S532; or S61 or S62), the console 21 provides a corresponding operational input to the controller 20.

Controller 20 includes a central processing unit (CPU) and is configured to receive operational inputs from console 21 to generate a control signal corresponding to the operational input. The storage device 23 includes a rewritable non-volatile semiconductor memory (such as EEPROM or flash memory) and stores images corresponding to each of the operation switches S51, S52 and S53 in a group or a group of states ( Each of S61 and S62) controls the identification code of the terminal 1; the multicast address; each identification code of the other operation terminal 2; and information such as the status of each load 17 in the collective control (lump control).

The indicator 25 is set to indicate the operational state of the load 17 corresponding to the operation switches S51, S52 and S53 (or S61 and S62). For example, the indicator 25 has light-emitting devices LD51, LD 52 and LD 53 (or LDs 61 and LD 62), such as light-emitting diodes, and a drive circuit for driving the light-emitting devices. When in a collective control, such as all the loads 17 in the group control or type control are illuminated (operated), the drive circuit responds to the control signal from the controller 20, and the corresponding illumination device LD51, LD 52 or LD 53 (or LD61 and LD62) is turned off. When all or part of the load 17 within the group control or type control is not illuminated (not operating), the drive circuit responds to the control signal from the controller 20 to turn on the corresponding illumination device. As shown in FIG. 3, the light-emitting devices LD51, LD52 and LD53 (or LD61 and LD62) are adjacent to the operation switches S51, S52 and S53 (or S61 and S62), respectively. The power source 26 is set to convert AC power of the commercial AC power source into DC power to provide DC power to each portion of the operation terminal 2.

The collective control will be described below in conjunction with FIG. Collective control includes group control and type control (also referred to as "scene control" for the luminous load of this example. In group control, all loads 17 included here are controlled by a group. In order to have the same operational state, in the type control, all the loads 17 are controlled by a group, but have individual operation states. In the first practical example, the operation switches S51-S53 of the operation terminal 2A correspond to The group control, and the operation switches S61 and S62 of the operation terminal 2B correspond to the type control. For example, in the group control corresponding to the operation switch S51, the load connected to all the operation control terminals of the signal line Ls (1A- The 17D of 1D is collectively lit or unlit. The identification codes of the operation control terminals 1A-1D in the group are related to the operation switch S51, and are stored in the storage device 23 of the operation terminal 2A. The type control of S61 (referred to herein as "first type control") includes all of the operation control terminals 1A-1D (first type group). In the first type control, the operation control terminals 1A and 1B are operated. Each load 17 is lit, and the operation Each load 17 of the control terminals 1C and 1D is adjusted to a dimming value of 50% and 70%, respectively. The identification code of the operation control terminals 1A-1D and the control command of each load 17 (such as a dimming value or A similar control content is associated with the operation switch S61 and stored in the storage device 23 of the operation terminal 2B. The type control corresponding to the operation switch S62 (referred to herein as "second type control") includes an operation control terminal. 1C and 1D (second type group). In the second type control, the load 17 of the operation control terminals 1C and 1D are respectively adjusted to have dimming values of 70% and 30%. Operation control terminals 1C and 1D The identification code and the control command of each load 17 (such as a dimming value or the like) are associated with the operation switch S62 and stored in the storage device 23 of the operation terminal 2B. By the way, all connections are made. Any one or more of the operation control terminals to the signal line Ls may be spontaneously included in a group control group or type control group. In the operation terminal 2, from any operation control terminal 1A Each load state of -1D is stored in storage device 23.

The operation of the group control will be described below. At the operation terminal 2A, when the operation switch S51 is manipulated, the console 21 provides an operation input (operation signal) to the controller 20. Next, the controller 20 acquires, from the storage device 23, the identification codes of the operation control terminals 1A to 1D associated with the operation switch S51 and each state of the load 17 to which they are connected. If each state of the load 17 is the same, the controller 20 generates a control command to invert each state of the load 17. If a portion of the load 17 is in the on state and the other is in the off state, the controller 20 generates a control command to set the load 17 to the same state. The controller 20 generates a packet by setting a control command to the data, setting the multicast address to the destination address, and setting the identification code of the operation terminal 2A to the source address (referred to herein as a "group packet" (group). Packet)"). The controller 20 then transmits the packet through the signal line Ls. As shown in FIG. 4B, the data may include command content, controlled objects, and control content. The command content includes a mode setting command for setting to an operation mode (load control), a registration mode, or the like. The control command includes at least one control content (eg, a charge or a turn off command for a load 17), and the at least one control content is combined with an identification code of the corresponding controlled object (eg, any one of the operation control terminals 1A-1D) . Therefore, when the packet includes a control command, at least one corresponding controlled object is also included in the packet. In the first practical example, a packet whose destination address includes a multicast address is transmitted to all terminals (operation control terminal 1 and other operation terminal 2) in the load control system. When the operation control terminal 1 includes a plurality of operation control switches, the identification code of the operation control terminal includes a plurality of identification codes (referred to herein as (a) "combination identification code"), and each combination identification code is an operation. The combination of the identification code of the control terminal itself and the identification code associated with the corresponding operational control switch. In an example, the operation control terminal 1B includes two identification codes, one of which is a combination of the identification code of the operation control terminal 1B itself and the identification code associated with the corresponding operation control switch S21, and the other is the operation control terminal 1B. A combination of its own identification code and an identification code associated with the corresponding operational control switch S22. The identification code of the operation control terminal (the identification code of the operation control terminal itself) can be set to any one of the destination address, the source address, and the controlled object, but the combination identification code can only be set as the controlled object. For example, the identification code of the operation control terminal itself and the identification code associated with the operation control switch can be set as the source address (or destination address) and the controlled object, respectively.

At the operation control terminals 1A-1D, each controller 10 receives a group packet through a corresponding transceiver 12. If the data of the group packet includes the identification code of the corresponding operation control terminal 1, each controller 10 provides a control signal to the corresponding driver 14 for driving the corresponding load 17 according to the control content combined with the identification code. The driver 14 turns the relay on or off according to the control signal to provide or stop providing energy to the load 17. After a predetermined waiting time has elapsed after receiving the control command, each controller 10 transmits a load status notification packet (referred to herein as a response packet) through the corresponding transceiver 12 and the signal line Ls. The waiting times of each of the operation control terminals 1A to 1D are different from each other. The destination address of the response packet is set as the source address of the group packet (the identification address of the operation terminal 2A). The source address of the response packet is set to the corresponding identification address of the operation control terminal 1. The response packet data includes a load status (status code), which is the latest status of the corresponding load 17. Further, each controller 10 changes the display (symbol) of the corresponding indicator 15 in response to a load state (e.g., a lighted or extinguished state).

At the operating terminal 2A, the controller 20 receives a response packet through the transceiver 12 and stores the load status in the response packet in the storage device 23. If each response packet is received from the operation control terminals 1A-1D included in the group corresponding to the operation switch S51, the controller 20 changes the display of the pointer 25 in response to each load state. For example, the controller 20 turns off the light-emitting device LD51 when all of the loads 17 are lit, and turns on the light-emitting device LD51 when all of the loads 17 are not lit. Therefore, the indicator 15 can display that all the loads 17 are operating (lighting) by turning off the light-emitting device LD51, and can also display that all the loads 17 are not operated (not illuminated) by turning on the light-emitting device LD51. Therefore, under the collective control, it is not necessary to provide a display device to individually display the load state, and the required judgment function can still be achieved.

If the controller 20 cannot receive a response packet (referred to herein as a "missing terminal") from any of the operation control terminals 1A-1D, the controller 20 transmits the packet through the transceiver 22 to the signal line Ls (at This is called "reminder packet". The destination address of the reminder packet is set to the identification code of the disconnected terminal (for example, 1D). The source address of the reminder packet is set to the identification code of the operation terminal 2A. The data for the reminder packet includes a control command for the packet requesting the load status notification. If the packet of the load status notification is received from the disconnected terminal, the controller 20 stores the load status in the packet in the storage device 23. Otherwise, for example, the controller 20 displays an abnormal (faulty) state by repeatedly switching the light-emitting device LD 51. After the controller 20 obtains a packet of the load status notification from each of the operation control terminals 1A-1D, the controller 20 transmits a packet (referred to herein as a "forward packet") via the transceiver 22. The information of the forwarding packet includes control commands for transferring the acquired load status to other operating terminals 2 (e.g., 2B). The destination address of the forwarding packet is set to a second multicast address. The second multicast address is an identification code only for operating the terminal 2, and is not used to operate the control terminals 1A-1D. The source address of the forwarding packet is set to the identification code of the operation terminal 2A. In the other operation terminal 2B receiving the forwarding packet, the controller 20 stores the latest load status in addition to storing the previous load status in the storage device 23, and then transmits a packet for receiving the acknowledgment (ACK packet) by unicast. (ACK packet)). At the operation terminal 2A, if the controller 20 cannot receive the ACK packet from the operation terminal 2B, the controller 20 retransmits the transfer packet to the operation terminal 2B by unicast.

The operation of the type control (second type control) will be described below with reference to FIG. At the operation terminal 2B, when the operation switch S62 is manipulated, the console 21 provides an operation input (operation signal) to the controller 20. In response to the operation input (ie, the operation switch S62), the controller 20 acquires at least one identification code (for example, 1C and 1D) of the operation control terminal associated with the operation switch S62 and at least one operation control terminal from the correspondence relationship in the storage device 23. The control content (for example, the dimming value of each of the operation control terminals 1C and 1D). The controller 20 then generates a control command in response to the control content of the at least one operation control terminal. For example, the controller 20 generates a control command for driving the load 17 of the operation control terminal 1C at 70% of the dimming value, and driving the load 17 of the operation control terminal 1D at the dimming value of 30%. The controller 20 then transmits a packet (referred to herein as a "pattern packet") to the signal line Ls via the transceiver 22. The type of packet information includes the generated control commands. The destination address of the type packet is set to the multicast address. The source address of the type packet is set to the identification code of the operation terminal 2B. The type packet does not include each identification code and control content of the second group of operation control terminals 1A and 1B.

At the operation control terminals 1A-1D, each controller 10 receives a type packet through the corresponding transceiver 12. In operating the control terminals 1A and 1B, their identification codes are not included in the type packet, so each controller 10 ignores the control command of the type packet, but transmits the load through the corresponding transceiver 12 and the signal line Ls. Packets for status notifications (response packets). The packet status of the load status notification includes the latest load status. In operating the control terminals 1C and 1D, their identification codes are included in the type packet, so each controller 10 provides a control signal to the corresponding driver 14 for adding the corresponding content according to the control content (dimming value). The identification code drives the corresponding load 17. Each of the drivers 12 adjusts the unit time power fed to the load 17 in accordance with the control content. Similarly, after operating the control terminals 1C and 1D, after a predetermined waiting time has elapsed after receiving the control command, each controller 10 transmits a packet of the load status notification (response packet) through the corresponding transceiver 12. The destination address of the response packet is set as the source address of the group packet (the identification address of the operation terminal 2B). The source address of the response packet is set to the identifier of the corresponding operation control terminal. The response packet data includes the latest status (dimming value) of a corresponding load 17. In addition, each controller 10 changes the display of the corresponding indicator 15 in response to the latest state.

At the operation terminal 2B, if the controller 20 receives the response packet through the transceiver 22, the controller 20 stores the load status contained in the response packet in the storage device 23. If all of the response packets are received from the second type group (1C and 1D) of the corresponding operation switch S62, the controller 20 turns on the light-emitting device LD62 to display the second type control. Upon receiving each response packet from the operational control terminals 1A-1D, the controller 20 generates a packet (referred to herein as a "transfer packet") for transmitting the forwarding packet through the transceiver 22 and the signal line Ls. The forwarding packet information includes control commands for forwarding the latest load status obtained from the response packet. The destination address of the forwarding packet is set to the second multicast address. The source address of the forwarding packet is set to the identification code of the operation terminal 2B. At the other operating terminal (e.g., 2A) that receives the forwarding packet, the controller 20 stores the latest load status in addition to storing the previous load status in the storage device 23. The operation of the first type control is basically the same as the operation of the second type control.

In the load control system, the load 17 connected to the terminal 1 can be directly driven by the operation control switch 110 of the operation control terminal 1. By processing the operation switch 210 of the control terminal 2, the load connected to the at least one operation control terminal of the terminal 2 through the signal line Ls can be remotely controlled. The operation terminal 2 transmits a packet including the control command to the at least one operation control terminal 1 through the signal line Ls, thereby avoiding the entire system failure caused by the damage of the signal line Ls or the operation of any one of the control terminal 1 and the operation terminal 2. situation. When a plurality of operation control terminals are remotely controlled by collective control, packets including control commands are transmitted to a plurality of operation control terminals 1 by multicasting instead of unicast, and thus can be controlled in a collective manner. A plurality of operation control terminals. Therefore, compared with the traditional central control system, both stability and load control response can be improved.

The registration procedure of the correspondence relationship of the collective control will be described below with reference to FIGS. 7 and 8.

In the case where the operation terminal 2B has registered the second type control, if the control mode switch 211 is manipulated, the console 21 provides an operation input (operation signal) to the controller 20. In response to the operational input, controller 20 changes its own control mode from an operational mode to a registration mode. In one example, the control mode switch 211 is a slide switch having a common contact and three contacts. Any contact can be connected to a shared contact. At these three contacts (position), the central contact (position) corresponds to the operating mode, and the two ends (position) of the contact correspond to the registration mode. One of the two ends of the contact is used to register the group control, and the other end is used to register the type control. However, not limited thereto, the control mode switch 211 may be a slide switch having a common contact and at least two contacts of the corresponding operation mode and the registration mode (for example, group control or type control), or any to be registered. It can be used to replace the operation switch of a unique control mode switch. For example, when the time of being manipulated (pressed) is longer than the time threshold for mode switching, the operation switch S62 can be used as the control mode switch 211.

In the registration mode, if the operation switch S62 is manipulated, the console 21 provides an operation input (signal) to the controller 20. The controller 20 displays the operation switch S62 to the user in the registration mode by repeatedly switching the light-emitting device LD 62. The controller 20 also transmits a packet (referred to herein as a "mode packet") to the signal line Ls via the transceiver 22. The data of the mode packet includes a mode setting command for setting the control mode of the controller 10 of each operation control terminal 1 to a registration mode. The destination address of the mode packet is set to a multicast address. The source address of the mode packet is set to the identification code of the operation terminal 2B.

In the operation control terminal 1 that receives the mode packet, each of the controllers 10 changes its own control mode to the registration mode according to the mode setting command. In an initial registration mode, none of the operation control terminals 1 are in the second type group. In this case, if a desired operation control switch 110 is pressed for a period longer than the time limit for registration, the operation control switch 110 can be incorporated into the second type group. For example, at the operation control unit 1C, if the operation control switch S31 is pressed for a period longer than the time limit for registration, the console 11 provides a time longer than the time limit for registration. The operational control is input to the controller 10. The controller 10 should operate the control input, change the registration (entry/nonentry) for the second type group to enter, and transmit a packet by unicast through the transceiver 12 and the signal line Ls ( This is referred to herein as a "registration packet". The information of the registration packet includes the changed result for displaying the entry into the second type group. The destination address of the registration packet is set to the identification code of the operation terminal 2B. The source address of the registration packet is set to the identification code of the operation control unit 1C. The controller 10 also displays the changed result to the user via the indicator 15. For example, in the case of entering the second type group, the controller 10 repeatedly switches the light emitting device LD31 in a relatively long period of time (first period). In the case of no entry, the controller 10 repeatedly switches the light-emitting device LD31 in a relatively short period of time (a second period shorter than the first period). At the operation terminal 2B, the controller 20 temporarily stores the changed result of the storage device 23 (requirement for entering the second type group).

Therefore, at the operation control unit 1D, if the operation control switch S41 is pressed for a period longer than the time limit for registration, the console 11 provides an operation control longer than the time threshold for registration. Input to controller 10. The controller 10 should operate the control input, change the registration (entry/nonentry) for the second type group to enter, and transmit a packet by unicast through the transceiver 12 and the signal line Ls ( This is called "registration packet". The information of the registration packet includes the changed result for displaying the entry into the second type group. The destination address of the registration packet is set to the identification code of the operation terminal 2B. The source address of the registration packet is set to the identification code of the operation control unit 1D. The controller 10 also displays the changed result to the user via the indicator 15. For example, in the case of entering the second type group, the controller 10 repeatedly switches the light emitting device LD41 in a relatively long period of time (first period). In the case of no entry, the controller 10 repeatedly switches the light-emitting device LD41 in a relatively short period of time (a second period shorter than the first period). At the operation terminal 2B, the controller 20 temporarily stores the changed result of the storage device 23 (requirement for entering the second type group).

Therefore, at the operation terminal 2B, if the user manipulates the control mode switch 211, the console 21 provides an operation input (operation signal) to the controller 20. Based on the changed result stored in the storage device 23, the controller 20 associates the identification codes of the operation control terminals 1C and 1D to the controlled object group (the second type group), and stores the associated identification code in the storage device 23 . The controller 20 then changes its own control mode from the registration mode to the operation mode. The controller 20 also transmits a packet (mode packet) through the transceiver 22 and the signal line Ls. The data of the mode packet includes a mode setting command for setting the control mode of each controller of the operation control terminal 1 to the operation mode. The destination address of the mode packet is set to a multicast address. The source address of the mode packet is set to the identification code of the operation terminal 2B. Upon receiving the operation control terminal 1 of the mode packet, each controller 10 changes its own control mode to the operation mode according to the mode setting command. In this case, regardless of whether the second type group is entered/not entered, each controller 10 does not store any material (the identification code of the operation terminal 2B, and the like) in the corresponding storage device 13. After the operation terminal 2B and the operation control terminal 1 are changed to the operation mode, each controller switches the corresponding light-emitting device. Likewise, the registration procedure can be implemented for controlled object groups other than the second type group.

In the operation mode, when the brightness of the load 17 of each of the operation control terminals 1C and 1D is adjusted via any one of the corresponding operation control switches (S32 and S33, or S42 and S43), the operation switch S62 of the operation terminal 2B is The controller 20B of the operation terminal 2B transmits the packet by unicast through the transceiver 22 when it is pressed for a period longer than the time limit for registration. The destination addresses of the packets are respectively set to the identification codes of the operation control terminals 1C and 1D associated with the operation switch S62 from the storage device 23 in the second type group. The information for each packet includes control commands or requests for the latest load status (dimming value). The source address of each packet is set to the identification code of the operation terminal 2B.

Upon receiving the packet's operation control terminals 1C and 1D, each controller 10 transmits a load status notification packet (response packet) through the corresponding transceiver 12 and the signal line Ls. The information in response to the packet includes the latest load status (dimming value) stored in the corresponding storage device 13. The destination address of the response packet is set to the identification code of the operation terminal 2B. The source address of the response packet is set to the identifier of the corresponding operation control terminal.

Upon receiving the response packet, the controller 20 stores the load status (dimming value) from the operation control terminals 1C and 1D in the storage device 23 under the second type control, respectively, as the control content of the corresponding load 17. . In an alternative example, the controller 20 of the operation terminal 2B acquires the load state (dimming value) of the operation control terminal 1 from the storage device 23, and stores the load state in the storage device 23 under the type control, as the load 17 Control content. That is, when each of the operation control terminals 1 drives the corresponding load 17, each terminal transmits the latest load state to the operation terminal 2B, and then the storage device 23 stores the latest load state of the operation control terminal 1 in advance. In the operation terminal 2A under the group control, since the control content (dimming value) of the load 17 is not required, the aforementioned operation is not essential.

Incidentally, when any of the controllers of the operation terminal (for example, 20 of 2B) and the controller 10 of the operation control terminal are in the registration mode, even if any other operation switches of the operation terminal 2 (for example, S51 of 2A) , S52, or S53) is manipulated, and the controller 20 of the terminal (e.g., 2A) does not generate a packet including a control mode for remote control (group control). In the registration mode, if the other operating terminal 2A generates a packet, the amount of traffic increases, which may affect the packet transmission between the operating terminal 2B and the operation control terminal 1 for registration. Therefore, in order to avoid affecting the registration, the aforementioned other operation terminals (for example, the operation terminal 2A) are prohibited from transmitting a packet including the control mode for the remote control. However, if such traffic increase does not affect the transmission capability of the system, the aforementioned other operational terminals (e.g., 2A) may transmit a packet including a control mode for remote control. In this case, the controller 10 of each of the operation control terminals 1 can be set to discard the packets from the other operation terminals described above.

Even in the registration mode, each of the operation control terminals can directly drive the corresponding load 17 in response to the operation control input from the corresponding operation control switch. Since it is impossible to increase the amount of traffic when each operation control terminal 1 drives the corresponding load 17 in response to the operation control input from the corresponding operation control switch.

Therefore, in the registration mode, the controller 10 of each of the operation control terminals 1 recognizes a first operation control input regarding the processing time of the corresponding operation control switch (S11; S21 or S22; S31; or S41) (for example, The punctuality is relatively short; and a second operational control input having a relatively long processing time (e.g., punctuality) with respect to the corresponding operational control switch (S11; S21 or S22; S31; or S41). Each controller 10, upon receiving the first operational control input, performs a process of controlling the corresponding load (its own load 17) and, when receiving the second operational control input, for the controlled target group, Register the program for switching selection (entry/no entry).

In the operation mode, the controller 10 of each of the operation control terminals 1 responds to the operation control input from the corresponding console 11 (S11; S21 or S22; S31; or S41), and executes the program for driving the corresponding load 17 without using When the operation control input is obtained (at the time point), the operation controls the time of the input. Therefore, the controller 10 of each of the operation control terminals 1 changes a response procedure between the operation mode and the registration mode. That is, in the registration mode, each controller 10 responds to the processing time between when the corresponding operation control switch (S11; S21 or S22; S31; or S41) is pressed to the release point, and recognizes two operation controls. Input (first and second operational control inputs). In the operation mode, each controller receives an operation control input when a corresponding operation control switch (S11; S21 or S22; S31; or S41) is pressed. The operational control input corresponds to a first operational control input in the registration mode.

In the first practical example, after an operation terminal 2 switches to the registration mode, if any of the operation control switches of the operation control terminal 1 are manipulated to provide a second operation control input to the corresponding controller 10, the controller 10 substitutes Switching for entry/non-entry of controlled object groups. Thereby, the storage device 23 of the operation terminal 2 can re-store the correspondence between the operation control input and the identification code. Therefore, even if the user does not have professional knowledge, the user can easily register the correspondence for collective control. In the registration mode, the controller 10 of each of the operation control terminals 1 is not used to control the corresponding load 17 even if an operation control input is received from the corresponding console 11. Therefore, it is possible to avoid the possibility that an error occurs when the registration process and the load control are executed at the same time (in the registration mode) (for example, the lighting load is not properly lit in the registration mode).

In the registration mode in which the identification code of the operation control terminal 1 is stored in the storage device 13 of the operation terminal 2, an operation control switch can be commonly used for load control and registration, and the operation control switch is immediately manipulated, thereby controlling the load 17. Therefore, in the case where the number of switches (operation control switches) is not required to be increased, the registration mode can be prevented from malfunctioning and the convenience can be improved. The user can also confirm the load status of each collective control object when performing registration, and the convenience can be improved. In the operation mode, when an operation control switch of the operation control terminal is processed, the corresponding load 17 is also immediately controlled, thereby improving convenience.

Second practical example

Fig. 9 shows a second practical example of the present invention. In this example, each of the operation terminals 2 is connected to a load (not shown) and is set to directly drive the load. That is to say, each of the operation terminals 2 and the operation control terminal 1 includes a drive. In other words, each of the operation terminals 2 (1A) can be classified as a main operation control terminal having a remote control function, and each of the operation control terminals 1 (1B, 1C, and 1D) can be classified as having no remote end. The secondary operation control terminal of the control function. In order to simplify the description, similar elements will have the same reference numerals as the first practical example.

The secondary operation control terminals 1B-1D are individually set in the same manner as the first practical example. The main operation control terminal 1A corresponds to the operation terminal 2 of the first practical example, and further includes the same configuration as the secondary operation control terminals 1B-1D.

In the main operation control terminal 1A, the operation switches (210) S51 correspond to the group control, and the operation switches S51 and S53 correspond to the aforementioned first and second type control, respectively. The operation switches S51-S53 are associated with a group under group control, or with the secondary operation control terminals 1B-1D included in a first or second type group under the first or second type control. The identification code is associated, as well as the control content (dimming value) of each load 17, which is stored in the storage device 23.

The operation of the main operation control terminal 1A will be described below with reference to FIG. When the operation switch S5 of the main operation control terminal 1A is manipulated, the console 21 supplies an operation input (operation signal) to the controller 20. By the correspondence stored in the storage device 23, the controller 20 acquires the identification code of the secondary operation control terminals 1B-1D related to the operation input, and the reception of the controlled object connected to the secondary operation control terminals 1B-1D. Controls the state of the object (load 17) (latest state). If the states are the same, the controller 20 generates a control command to reverse the state of the load 17. For example, if all of the load 17 associated with switch S51 is in the illuminated state, a control command to turn off load 17 is generated, and if load 17 is in the extinguished state, a control command to turn on load 17 is generated. If the states are different, the controller 20 generates a control command to set the load 17 to the same state. For example, if any one of the loads 17 is in the on state and the other is in the off state, the controller 20 generates a control command to set the load 17 to the on or off state. The controller 20 then transmits the packet through the transceiver 22 to the signal line Ls. The information of the group packet includes control commands. The destination address of the group packet is set to the multicast address. The source address of the group packet is set as the identification code of the primary operation control terminal 1A.

At the secondary operation control terminals 1B-1D, each controller 10 receives a group packet through a corresponding transceiver 12. If the data of the group packet includes the identification code of the corresponding secondary operation control terminal, each controller 10 provides a control signal to the corresponding driver 14 according to the combination of the control content and the identification code for driving the corresponding load 17. The driver 14 switches the relays according to the control signals to provide or stop providing energy to the load 17. After a predetermined waiting time has elapsed after receiving the control command, each controller 10 transmits a load status notification packet (response packet) through the corresponding transceiver 12 and the signal line Ls. The waiting times of each of the operation control terminals 1A to 1D are different from each other. The destination address of the response packet is set as the identification code of the primary operation control terminal 1A (the source address of the group packet). The source address of the response packet is set to the identifier of the corresponding secondary operation control terminal. The response packet data includes the latest status (lighted or extinguished) of the corresponding load 17. Further, each controller 10 changes the display (symbol) of the corresponding indicator 15 in response to the latest load state.

At the primary operating terminal 1A, the controller 20 receives a response packet through the transceiver 22, and then stores the load status in the response packet in the storage device 23. If each of the response packets is received from the secondary operation control terminals 1B-1D included in the group corresponding to the operation switch S51, the controller 20 changes the display of the pointer 25. For example, the controller 20 turns off the light-emitting device LD51 when all of the load 17 associated with the operation switch S51 is lit; and turns on the light-emitting device LD51 when all the loads 17 associated with the operation switch S51 are not illuminated. If the controller 20 cannot receive the response packet ("missing terminal") from any of the secondary operation control terminals 1B-1D, the controller 20 transmits the packet through the transceiver 22 to the signal line Ls ("Reminder packet" (reminder packet)"). The destination address of the reminder packet is set to the identification code of the disconnected terminal (for example, 1D). The source address of the reminder packet is set as the identification code of the primary operation terminal 1A. The data for the reminder packet includes a control command for the packet requesting the load status notification. If the packet of the load status notification is received from the disconnected terminal (1D), the controller 20 stores the load status in the packet in the storage device 23. Otherwise, for example, the controller 20 displays an abnormal (faulty) state by repeatedly switching the light-emitting device LD 51.

The operation of the type control (second type control) will be described below with reference to FIG. At the main operation control terminal 1A, when the operation switch S53 is manipulated, the console 21 provides an operation input (operation signal) to the controller 20. The controller 20 obtains the identification code of the secondary operation control terminals 1C and 1D associated with the operation input and the control content of the load 17 connected to the terminals 1C and 1D by the correspondence stored in the storage device 23 in response to the operation input ( Dimming value). In response to the control content (second type control), the controller 20 generates a control command for driving the load 17 of the secondary operation control terminal 1C at 70% of the dimming value, and driving at 30% of the dimming value. The load 17 of the control terminal 1D is to be operated. The controller 20 then transmits the packet (type packet) to the signal line Ls through the transceiver 22. The type of packet information includes control commands. The destination address of the type packet is set to the multicast address. The source address of the type packet is set as the identification code of the primary operation control terminal 1A. The type packet does not include the identification code of the secondary operation control terminal 1B of the second type group.

At the secondary operation control terminals 1B-1D, each controller 10 receives a type packet through the corresponding transceiver 12. In the secondary operation control terminal 1B, the identification code is not included in the type packet (the control command (control content) in the combination type packet is not combined), so the controller 10 ignores the control command, but transmits the corresponding transmission and reception. The device 12 and the signal line Ls transmit a packet of the load status notification (response packet). The packet data of the load status notification includes the latest load status of the load 17. In the secondary operation control terminals 1C and 1D, their identification codes are included in the packets (combined with the control contents in the packets, respectively), so each controller 10 provides a control signal to the corresponding driver 14 for control according to the control. The content (dimming value) is added to the corresponding identification code to drive the corresponding load 17. Each of the drivers 14 adjusts the power per unit time fed to the load 17 in accordance with the corresponding control signal. After a predetermined waiting time has elapsed after receiving the control command, each controller 10 transmits a load status notification packet (response packet) through the corresponding transceiver 12 and the signal line Ls. The destination address of the response packet is set to the source address of the type packet (the identification code of the primary operation control terminal 1A). The source address of the response packet is set to the identifier of the corresponding secondary operation control terminal. The response packet data includes the latest status (dimming value) of a corresponding load 17. In addition, each controller 10 changes the display of the corresponding indicator 15 in response to the latest state.

At the primary operational control terminal 1A, the controller 20 receives the response packet through the transceiver 22 and stores the load status in the packet in the storage device 23. If the controller 20 receives all of the response packets from the secondary operation control terminals 1C and 1D in the second type group associated with the operation switch S53, the controller 20 displays the executed by turning on the light-emitting device LD 53. Second type control. The operation of the first type control is basically the same as the second type control.

In the second practical example, if the control mode switch of the main operation control terminal 1A is manipulated (pressed or slid), the controller 20 changes its own control mode. For example, changing from the operating mode to the registration mode. The controller 20 also multicasts a packet including a mode setting command through the transceiver 22 and the signal line Ls, including a mode setting command for specifying a registration mode. Upon receiving the secondary operation control terminals 1B-1D of the packets, each controller 10 changes its own control mode from the operation mode to the registration mode. In the registration mode, the identification code required for the secondary operation control terminals 1B-1D may be associated with a controlled object group of the primary operation control terminal 1A as described in the first practical example.

Third practical example

In Fig. 3, when the operation terminals 2A and 2B are changed to the registration mode at the same time, an error may occur. For example, the operation control terminal 1 to be associated with one of the operation terminals 2A and 2B may be associated with both. Therefore, when any one of the operating terminals is in the registration mode, it is preferable that the control mode of the other terminal cannot be changed to the registration mode. After the operation control terminal 1 connected to the signal line Ls changes its own control mode to the registration mode according to a mode setting command, the other operation control terminal 1 is connected and activated, and cannot receive the mode setting command, so the control cannot be performed. The mode changes to the registration mode. Therefore, after the transfer mode setting command, it is necessary to also change the control mode of the activated operation control terminal 1.

In the third practical example, if the controller 20 of each of the operation terminals (for example, 20 of 2B) changes its own control mode to the registration mode, each controller 20 repeatedly transmits the packet including the mode setting command. It is used to designate a registration mode for all operation control terminals and other operation terminals 2 at a fixed interval (for example, at intervals of several seconds) until another packet including the mode setting command is transmitted to be set to the operation mode. In order to simplify the description, similar elements have the same reference numerals as the first practical example.

The operation of the third practical example will be described below with reference to FIG. At the operation terminal 2B, if the control mode switch 211 of the console 21 is manipulated, the console 21 provides an operation input (operation signal) to the controller 20. The controller 20 then changes its own control mode from the operational mode to the registration mode. When the operation switch S62 of the operation terminal 2B is manipulated, the controller 20 generates a mode setting command for designating a registration mode. The controller 20 then transmits a registration mode notification packet (referred to herein as a "mode packet") to the signal line Ls via the transceiver 22, and includes a mode setting command. The data of the mode packet includes a mode setting command. The destination address of the mode packet is set to a multicast address. The source address of the mode packet is set to the identification code of the operation terminal 2B. The mode packet is repeatedly transmitted by the multicast method at a fixed interval.

At the operation control terminal 1, each controller 10 changes its own control mode from the operation mode to the registration mode according to the mode setting command in the mode packet, and simultaneously starts a counter (timer). For example, even if any one of the operation control terminals (for example, 1B) is started after the first mode packet transmission of the operation terminal 2B, the operation control terminal 1B can receive other subsequent mode packets. Thereby, the operation control terminal 1B can also change the control mode from the operation mode to the registration mode. Therefore, the storage device 13 of the operation control terminal 1B requests the multicast addresses of the other operation control terminals 1 and the operation terminal 2 stored in the storage devices 13 and 23. However, a broadcast address can also be used to broadcast mode packets in a broadcast manner instead of a multicast address.

In operating the control terminal 1, each controller 10 resets its counter as soon as it receives the mode packet. Each controller 10, when its counter value (measured time) exceeds a predetermined time (time threshold for automatic recovery) longer than the cycle time of repeatedly transmitting the module packet, The control mode is changed to the operation mode. For example, it can be judged that the operation terminal 2B interrupts the transmission of the mode packet. Therefore, even if the operation terminal 2B interrupts the transmission of the mode packet due to the damage, the controller 10 of each of the operation control terminals 1 can automatically change its control mode to the operation mode. Therefore, the malfunction of the system can be avoided.

In the case where one of the operation terminals 2 (for example, 2B) is in the registration mode, if the console 21 of the other operation terminal 2 (for example, 2A) provides an operation input (signal) to the controller 20, the controller 20 is When the operation input is obtained, the counter is started. The controller 20 ignores the operation input if the mode packet is received from the operation terminal 2B before the value of the counter exceeds the time threshold for automatic restoration. If the value of the counter exceeds the time threshold for automatic recovery, and the controller 20 does not receive the mode packet, the controller 20 changes the control mode from the operation mode to the registration mode. At the operation terminal 2A, the controller 20 instructs to change the operation error of the registration mode (error notification) by quickly switching the light-emitting devices LD51-LD53, and ignores the aforementioned operation input. However, it is not limited thereto, and for example, the error notification can also be implemented by making the buzzer sound.

In the third practical example, since the operation terminals (for example, 2A and 2B) do not change their control modes to the registration mode, it is possible to prevent the storage device 23 of each operation terminal 2 from storing an erroneous correspondence (controlled) Target group).

Incidentally, when any controller 20 of the operation terminal 2 (for example, 20 of 2B) and any controller 10 of the operation terminal 1 are in the registration mode, even if another operation switch operates the terminal 2 (for example, 2A) The operating switch is manipulated and the controller (eg, 20 of 2A) does not generate a packet for remote control (group control). If the amount of traffic in the system increases due to the packet controlled by the far end, the increased amount of traffic may affect the packet transmission between the operation terminal 2B and the operation control terminal 1. In order to avoid such an influence, the operation terminal 2 (for example, 2A) prohibits transmission of a packet for remote control in the registration mode. However, if the increased amount of traffic does not affect the aforementioned packet transmission work, the operation terminal 2A can transmit a packet for remote control in the registration mode, and the controller 10 of each operation terminal 1 can discard the packet.

Even in the registration mode, the controller 10 of each of the operation control terminals 1 can directly drive the corresponding load 17 in response to the operation control input from the corresponding operation control switch. Since it is impossible to increase the amount of traffic when each operation control terminal 1 drives the corresponding load 17 in response to the operation control input from the corresponding operation control switch.

The third practical example can be applied to the second practical example. In the case where the load control system includes the main operation control terminal, when each terminal changes its own control mode to the registration mode under the control of any one of the main operation control terminals, the controllers of other main operation control terminals may also The corresponding operation switch is responded to like the second operation control terminal 1B-1D, and is selected to enter or not to enter (register) the controlled target group.

Fourth practical example

In FIG. 3, the controller 20 of each of the operation terminals 2 updates a remote control (collective control) state and a state (display content) of the corresponding indicator 25 in response to the latest load state stored in the corresponding storage device 23. If the latest load state of the storage device 23 stored in an operation terminal 2 does not match the actual load state, the remote control (collective control) of the operation terminal 2 or the load state of the corresponding indicator 25 may malfunction. For example, in some power engineering, after a remote control correspondence has been registered for the operation terminal 2, such an inconsistency may occur when an operation control switch is manipulated and an operation terminal does not obtain energy.

In the fourth practical example, each of the controllers 20 of the operation terminal 2 executes a program for acquiring the latest load state from each of the operation control terminals 1 at the time of startup (when it is activated in response to the power distribution from the power source). Each controller 20 then updates the corresponding storage device 23 by storing the latest load status obtained by each of the operation control terminals 1.

The operation of the fourth practical example will be described below with reference to FIG. At the operation terminal 2A, when the controller 20 is activated, the controller 20 transmits a packet (referred to herein as "activation packet") to the signal line LS through the transceiver 22. The information for starting the packet includes a response request (a control command (request for order) that requires a response in order to confirm the existence). The destination address of the boot packet is set to a multicast address. The source address of the boot packet is set to the identification code of the operation terminal 2A.

At the operation control terminals 1A-1D, each controller 10 receives an activation packet through a corresponding transceiver 12. After a predetermined waiting time has elapsed after receiving the start packet (response request), each controller 10 transmits a load status notification packet (response packet) through the corresponding transceiver 12 and the signal line Ls. The destination address of the response packet is set to the source address of the boot packet (the identification address of the operation terminal 2A). The source address of the response packet is set to the corresponding identification address of the operation control terminal 1. The response packet data includes the latest status of the corresponding load 17 (latest load status). At the operation terminal 2B, the controller 20 receives the response packet through the transceiver 22. The controller 20 stores the source address of the boot packet (the identification code of the operation terminal 2A) in the storage device 20. The controller 20 then transmits an ACK packet to the signal line Ls via the transceiver 22. The destination address of the ACK packet is set to the source address of the boot packet (the identification code of the operation terminal 2A). The source address of the ACK packet is set to the identification code of the operation terminal 2B.

At the operation terminal 2A, if the controller 20 receives the response packets from the operation control terminals 1A-1D through the transceiver 22, respectively, the controller 20 stores each of the load states included in the response packet. If the controller 20 also receives the ACK packet from the operation terminal 2B through the transceiver 22, the controller 20 stores the destination address of the ACK packet (identification code of the operation terminal 2B) in the storage device 23 for transmitting the aforementioned forwarding packet. .

Each of the controllers 20 of the operation terminal can also acquire each load state from the operation control terminal 1, as shown in FIG. That is, when the controller 20A of the operation terminal 2 is activated, the controller 20 sets the identification code of the terminal stored in the storage device 23 as the destination address of the startup packet, and transmits it through the transceiver 22 and the signal line Ls. Start the packet. The controller 20 transmits the boot packets to the operation control terminals 1A-1D, respectively, in unicast. At the operation control terminals 1A-1D, each controller 10 transmits a load status notification packet (response packet) to the operation terminal 2A. At the operation terminal 2A, if the controller 20 receives the response packet from the operation control terminals 1A-1D through the transceiver 22, the controller 20 stores the load status in the response packet in the storage device 23. The controller 20 also transmits the boot packet to other operating terminals 2 (e.g., 2B) using multicast. In the operation terminal 2B, if the controller 20 receives the boot packet through the transceiver 22, the controller 20 stores the destination address of the boot packet (the identification code of the operation terminal 2A) in the storage device 23. In the operation terminal 2A, if the controller 20 receives the ACK packet from the operation terminal 2B, the controller 20 stores the destination address of the ACK packet (identification code of the operation terminal 2B) in the storage device 23.

In FIG. 13 or FIG. 14, for the operation terminal 2A, when the controller 20 cannot receive a response packet from a certain operation control terminal 1A-1D (herein referred to as "missing terminal"), control is performed. The device 20 transmits a packet (alert packet) through the transceiver 22 and the signal line Ls. The destination address of the reminder packet is set to the identification code of the disconnected terminal (for example, 1D). The destination address of the reminder packet is set to the identification code of the operation terminal 2A. The data of the reminder packet includes a control command for the packet requesting the load status notification. If the packet of the load status notification is received from the disconnected terminal, the controller 20 stores the load status included in the packet in the storage device 23. Otherwise, the controller 20 indicates a failure such as the operation control terminal 1D being detached or damaged (error notification) or the like by causing the light-emitting diode LD 51 to be turned on and off.

In the fourth practical example, an operation terminal 2 can acquire the latest state of each load connected to the operation control terminal 1 at the time of startup. Therefore, it is possible to avoid a failure that occurs when the load state stored in the storage device 23 of the operation terminal 2 does not match the actual load state. The correspondence between the identification codes including the operation control terminals 1A-1D is required in the remote control of the operation terminal 2, but the identification codes of the other operation terminals 2 are not used for remote control, but for transferring the load status. Therefore, if the storage device 23 includes a rewritable non-volatile semiconductor memory and a volatile semiconductor memory, and the correspondence required for remote control is stored in the non-volatile semiconductor memory, the system The convenience can be improved. If information for remote control (the identification code of other operating terminal 2) is not stored in the volatile memory, the required capacity of the volatile semiconductor memory can be reduced. However, if the information for the remote control (the identification code of the other operation terminal 2) is not required to be stored in the non-volatile semiconductor memory, the presence of the other operation terminal 2 can be confirmed at the time of startup.

In Fig. 13, if the controller 20 of the operation terminal 2A is activated, the controller 20 transmits the startup packet through the transceiver 22 and the signal line Ls by multicast. If the controller 10 of the operation terminals 1A-1D and the controller 20 of the operation terminal 2B receive the startup packet through the transceivers 12 and 22, the controllers 10 and 20 transmit the response packet and the ACK through the transceivers 12 and 22, respectively, through the transceivers 12 and 22. The packet is packetized to the operation terminal 2A. In general, multicast transmissions are less reliable than unicast transmissions. Therefore, as the response is requested, the packet should be transmitted in multicast. The response packet and the ACK packet shall be transmitted unicast as the assuredness is required instead of the response being requested. This achieves a good balance of signal transmission.

The fourth practical example can be applied to the second practical example. The controller 20, which mainly operates the control terminal 1A, transmits a start packet at the time of startup, thereby receiving the latest load state from each of the secondary operation control terminals 1B-1D. Therefore, it is possible to avoid a failure that occurs when the load state of the storage device 23 stored in the primary operation control terminal 1A does not match the actual load state.
