Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring control system having a level control terminal which can be used for dimming control of a lighting load, control of the angle of a blade of a blind or control of elevation of a blind. is there.

[0002]

2. Description of the Related Art Conventionally, a load is connected to a control terminal device having an address, and address data of a transmission signal transmitted from another device through a signal path is preset in the control terminal device. A remote monitoring control system has been proposed in which the control terminal controls the load based on the control data contained in the transmission signal when the address matches. In this type of remote monitoring control system, it is proposed to transmit a signal specifying a level (light output or opening / closing amount) so that the light output of a lighting load used as a load or the opening / closing amount of a blind can be controlled. ing.
For example, the operating side is provided with an up switch for designating a rise and a down switch for designating a descending direction for instructing the start and end of level control and the direction in which the level should change. There is one that transmits a signal indicating a level as data to a control terminal. With this configuration, a transmission signal including control data whose level sequentially changes at appropriate time intervals is transmitted to the control terminal device.

[0003]

By the way, the transmission signal is time-division multiplexed, and control data is sequentially transmitted to each control terminal. Therefore, if the operating side and the control side are in one-to-one correspondence, no particular problem occurs. However, when attempting to associate a plurality of control sides with one operating side, each control terminal Since the transmission signals including the control data having different levels arrive at different times at different times, the timing of the level change of the load controlled by each control terminal device varies. For example, if the lighting loads connected to the plurality of control terminals are each tried to be dimmed step by step, the timing of the change in the light output of each lighting load is deviated, which causes a feeling of strangeness. In other words, since different addresses are set in the control terminals, it is impossible for a plurality of control terminals to receive transmission signals at the same time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a level control transmission signal that can be received by a plurality of control terminals at the same time. It is to provide a remote monitoring control system including a control terminal.

[0005]

In order to achieve the above object, the invention of claim 1 has an individual address set for each and a group address set to the same address within a predetermined group, and a signal. When the address data contained in the transmission signal transmitted by time division multiplexing on the path matches one of the individual address and the group address, the multiple units that control the operation level of the load according to the control data contained in the transmission signal Group control terminal for transmitting a transmission signal including the group address as address data to the signal path when the operation section is operated, the level control terminal having the level control terminal and the operation section for instructing the operation level of the load. It is equipped with a vessel.

According to this structure, a level control terminal having two types of addresses, that is, an individual address and a group address, is provided, and a plurality of level control terminals have the same address for the group address. By designating the address and indicating the operation level, the same control data can be received at a plurality of level control terminals at the same time. As a result, even when collectively controlling a plurality of level control terminals, it is possible to control the loads all at once without causing a deviation in load control timing in each level control terminal.

According to a second aspect of the present invention, in the first aspect of the present invention, an individual level control terminal unit is provided which has an operating section for instructing an operation level of the load and is associated in advance when the operating section is operated. An individual operation terminal device for transmitting a transmission signal including an address as address data on the signal path is provided. That is, not only is control data transmitted to a plurality of level control terminals all at once using a group address, but individual loads are also used to individually provide control data to each level control terminal by using individual addresses. Can be controlled. as a result,
It is possible to perform simultaneous control by grouping a plurality of level control terminals and individual control for each level control terminal.

According to a third aspect of the present invention, in the second aspect of the invention, the signal path is a signal line connected to a transmission control device, and the level control terminal device, the group operation terminal device, and the individual device. The operation terminal device is branched and connected to the signal line, and the group operation terminal device and the individual operation terminal device transmit information regarding a load operation level to the transmission control device when the operation unit is operated. However, the level control terminal receives the transmission signal sent from the transmission control device to the signal path, and if the address data included in the transmission signal matches one of the group address and the individual address, the level control terminal includes the transmission signal. The load is controlled at the operation level designated by the control data.

This configuration is a preferred embodiment, in which data is exchanged between the individual operation terminal device or the group operation terminal device and the level control terminal device through the transmission control device. It becomes possible for the transmission control device side to collectively manage the transmission signals transmitted through the signal lines. For example, if the transmission control device manages the correspondence between the terminals on the operating side and the control side, the correspondence can be easily managed.

According to a fourth aspect of the present invention, in the invention of the third aspect, the individual operation terminal includes a level display section for displaying an operation level of a load, and a plurality of groups are operated by operating the operation section of the group operation terminal. When the operation level of the load connected to each level control terminal changes, the level display of each individual operation terminal with a corresponding relationship is displayed from each level control terminal. That is, the return data for matching with is sent at different times.

In this configuration, when the group operation terminals are operated and the load operation level is controlled by the plurality of level control terminals, the individual operation having a correspondence relationship with each level control terminal is performed. Since the load operation level can be displayed on the level display unit of the operation terminal, even when the group operation terminal is controlled, each individual operation terminal can know the operation level of the load. In other words, the operation level display on the individual operation terminal device can be linked by the operation of the group operation terminal device.

The invention of claim 5 is characterized in that, in the invention of claims 1 to 4, the load is an illumination load and the operation level is a light output. A sixth aspect of the present invention is characterized in that, in the first to fourth aspects, the load is a blind whose blade plate angle is electrically controllable, and the operation level is the blade plate angle. .

The inventions of claims 5 and 6 are preferred embodiments as a load.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention basically has a system configuration shown in FIG. 1 and performs control in the procedure as shown in FIG. 3 or 4. First, the basic configuration of the remote monitoring control system will be described. In the present embodiment, the operation side includes the individual operation terminal device 10a and the group operation terminal device 10b, and the control side includes the level control terminal device 20. The level control terminal 20 has a lighting load L as a load.
Is connected, and the light output of the lighting load L can be adjusted according to the operation on the operation terminals 10a and 10b. Therefore, the operating terminals 10a, 10b
Is an up switch US for instructing an increase in the light output, a down switch DS for instructing a decrease in the light output, a plurality of light emitting diodes arranged in a line, and a level for displaying the instructed light output according to the number of lighted diodes. Display LD
And an on / off switch S for instructing turning on / off of the lighting load L.

An appropriate number of individual operation terminals 10a, group operation terminals 10b, and level control terminals 20 are provided and connected to the transmission control device 30 via a two-wire signal line Ls. Individual addresses are set in the operation terminals 10a and 10b and the level control terminal 20, respectively, and a group address is also set in the level control terminal 20. The individual address is set differently in each of the operation terminals 10a and 10b and the level control terminal 20, and the group address is set to be the same in the plurality of level control terminals 20 to be grouped. There is. As described above, the main feature of the present invention is that the level control terminal 20 has two types of addresses, the individual address and the group address. Transmission control device 3
At 0, the operation terminals 10a and 10b and the level control terminal 20 are recognized using the above-mentioned individual address and group address.

The transmission control device 30 sends the signal line Ls to
The transmission signal Vs having the format shown in FIG. 2A is transmitted. That is, the synchronization signal SY indicating the start of signal transmission, the mode data MD indicating the mode of the transmission signal Vs, the address data AD for calling the operation terminals 10a and 10b and the level control terminal 20, and the lighting load L are controlled. The control data CD, the checksum data CS for detecting a transmission error, and the bipolar (the signal return period WT, which is a time slot for receiving the return signals from the operation terminals 10a and 10b and the level control terminal 20) ( It is a time-division multiplexed signal of ± 24 V), and data is transmitted by pulse width modulation (FIG. 2 (b)). In each of the operation terminals 10a and 10b and each of the level control terminals 20, when the address data AD transmitted by the transmission signal Vs received through the signal line Ls matches the preset address, the transmission signal Vs The control data CD is taken in from and the data is returned as a current mode signal (a signal sent by short-circuiting the signal line Ls via an appropriate low impedance) during the signal return period WT of the transmission signal Vs.

When data is transmitted from the transmission control device 30 to the desired operation terminals 10a and 10b and the level control terminal 20, the mode data MD is set to the control mode,

The a, 10b or the terminal 20 for level control receives the control data CD and returns a signal in which a parity bit is added to the control data CD during the signal return period WT. The transmission control device 30 confirms that the control data CD has been transmitted to the desired operation terminal 10a, 10b or the level control terminal 20 by matching the transmitted signal with the received signal in the signal return period WT. Further, the level control terminal device 20 controls the load according to the received control data CD (in the operation terminal devices 10a and 10b, the operation level is displayed on the level display portion LD according to the received control data CD).

On the other hand, the transmission control device 30 always sends out the transmission signal Vs in which the mode data MD is in the dummy mode at regular time intervals, and the operation terminals 10a and 10b and the level control terminal 20 perform transmission control. When some information is to be transmitted to the device 30, an interrupt signal as shown in FIG. 2C is generated in synchronization with the synchronization signal SY of the dummy mode transmission signal Vs. At this time, the operation terminals 10a and 10b and the level control terminal 20 set an interrupt flag to prepare for the subsequent exchange of information with the transmission control device 30. When the transmission control device 30 receives the interrupt signal, the mode data MD is set to the interrupt polling mode and the upper half bits of the address data AD (address data AD
Is 8 bits, the transmission signal is transmitted while sequentially increasing the upper 4 bits, and the operation terminals 10a and 10b and the level control terminal 20 that generated the interrupt signal are transmitted in the interrupt polling mode. When the upper 4 bits of the address data AD of the same coincide with the upper 4 bits of the address set in the operation terminals 10a and 10b and the level control terminal 20, the lower half of the address in the signal return period WT The bits are returned to the transmission control device 30. In this way, the transmission control device 30 collectively searches for the 16 operation terminals 10a and 10b and the level control terminals 20 that have generated the interrupt signal, so that the operation terminal 1 can be searched in a relatively short time.
0a, 10b, the terminal 20 for level control can be discovered. When the transmission control device 30 acquires the addresses of the operation terminals 10a and 10b and the level control terminal 20 that have generated the interrupt signal, the mode data MD is set to the monitoring mode, and the transmission signal having the acquired address data AD is signaled. It is sent to the line Ls, and the operating terminals 10a, 1
0b, the level control terminal 20 returns information to be transmitted in the signal return period WT. Finally, the transmission control device 30 controls the operation terminal device 10 that has generated the interrupt signal.
a, 10b, a signal for instructing an interrupt reset is sent to the level control terminals 20, and the operation terminals 10a, 1
0b, the interrupt flag of the level control terminal 20 is cleared. As described above, the operation terminals 10a, 10b,
Information transmission from the level control terminal 20 to the transmission control device 30 is performed by the transmission control device 30 from the operation terminals 10a, 1
0b, signal transmission to the level control terminal 20 four times (dummy mode, interrupt polling mode, monitoring mode, interrupt reset) completes. The transmission control device 30 has desired operation terminals 10a and 10b and a level control terminal 2
When trying to know the operating state of 0, the mode data M
It is only necessary to send the transmission signal with D as the monitoring data.

As is apparent from the above-described operation, in the transmission control device 30, when any of the up switch US, the down switch DS, and the on / off switch S provided in the operation terminals 10a and 10b is operated, the operation is performed. Terminal 10
Based on the operation data returned from a and 10b, the control data to be transmitted to the level control terminal 20 in which the correspondence with the operation terminals 10a and 10b is preset by the address is generated, and the control data is generated. Is transmitted to the signal line Ls, control data is transmitted to the corresponding level control terminal device 20, and the lighting load L is controlled.

Processes data exchanged with 0.

The addresses of the operating terminals 10a and 10b are stored in the address storage unit 15 which is an EEPROM which is a non-volatile memory. Further, in order to set an address in the address storage section 15, an optical transmission / reception circuit 16 capable of exchanging address data with the setter X using an optical wireless signal is provided. The setter X can set an address in the address storage unit 15 by an optical wireless signal, read the address stored in the address storage unit 15 and confirm it, and check the address stored in the address storage unit 15. It also has the ability to modify. An address corresponding to the individual address of the level operation terminal 20 is set in the individual operation terminal device 10a, and an address corresponding to the group address of the level operation terminal device 20 is set in the group operation terminal device 10b. The power supply for the internal circuits of the operation terminals 10a, 10b is obtained by full-wave rectifying and stabilizing the transmission signal Vs transmitted through the signal line Ls by the electric wire circuit 17.

On the other hand, as shown in FIG. 6, the level control terminal device 20 basically has a configuration similar to that of the operation terminal devices 10a and 10b, but the signal processing unit 23 receives the received signal. The dimming data is generated based on the control data of the signal Vs, the dimming data is given to the dimming CPU 22, the dimming CPU 22 controls the dimming control circuit 21, and the dimming control circuit 21 controls the inverter circuit or the phase control. The circuit is used to change the light output of the lighting load L and to turn on / off the power supply to the lighting load L. That is, the operation terminal device 10
When the up switch US and the down switch DS are operated in a and 10b, control data for increasing or decreasing the light output is sequentially input to the level control terminal device 20, and the lighting load L of the lighting load L is received every time the transmission signal Vs is received. The light output changes. In addition, the operation terminals 10a, 10
When the on / off switch S is operated in b,
The lighting load L is turned on or off by receiving the transmission signal Vs. Here, the configurations denoted by reference numerals 23 to 27 in FIG. 6 have the same functions as the configurations denoted by reference numerals 13 to 17 in FIG. However, the signal processing unit 23
Generates the dimming data as described above, and changes the light output of the illumination load L and then returns information indicating the light output, which is different in operation. Furthermore, the operating terminal 10a,
In 10b, only one address is stored in the address storage unit 15, but it is different in that two addresses are stored in the address storage unit 25 of the level control terminal device 20 if necessary. That is, the address storage unit 25 stores the group address in addition to the individual address.
The individual address is set differently in each level control terminal 20, and the group address is set in common with some other level control terminals 20.

The operation by the operation of the individual operation terminal 10a is as shown in FIG. Now, assuming that the up switch US is operated by one individual operation terminal 10a (1), an interrupt signal is generated to interrupt the operation of the transmission control device 30 (2). The transmission control device 30 finds the individual operation terminal device 10a that has generated the interrupt signal (3), and returns operation information to the effect that it controls to increase the light output of the lighting load L from the individual operation terminal device 10a. (Four) . Based on this information, the transmission control device 30 transmits a transmission signal Vs containing control data instructing to increase the optical output to the level control terminal 20 (5). Here, to which level control terminal device 20 the transmission signal Vs is sent is determined by the address of the individual operation terminal device 10 a and the level control terminal device 2.
Depending on the correspondence with the individual address of 0, the transmission control device 3

Upon receiving the transmission signal Vs, the level control terminal device 20 controls the lighting load L and then returns information on the dimming level after the control to the transmission control device 30 (6). This information is returned from the transmission control device 30 to the individual operation terminal 10a that first operated the up switch US (7), and the level display section L of the individual operation terminal 10a is returned.
D is displayed. Here, the up switch US has been described, but the down switch DS is also the same, and the only difference is that the control data of the on / off switch S instructs turning on / off of the lighting load L.

On the other hand, when the up switch US is operated by the group operation terminal 10b, the operations (1) to (3) are the same as those of the individual operation terminal 10a, as shown in FIG. become. Here, the group operation terminal 10b self-manages the display of the level display unit (including the display of ON / OFF of the lighting load L) DL, and at the time of operating the up switch US, the transmission control device 30 displays the current level together with the operation information. To (4). The transmission control device 30 sends a transmission signal Vs in which the address data is the group address of the level control terminal device 20 (5), and a plurality of level control terminal devices 20 having the same group address are set.
Therefore, the transmission signal Vs can be received at the same time. Further, the transmission control device 30 is the group operation terminal 1

When the light output of the lighting load L is controlled by each of the plurality of level control terminals 20 designated by the group address, each level control terminal 20 is ordered in a predetermined order of priority (for example, , CMSA / CD eliminates the collision), and returns the dimming level of the lighting load L in order (7) (9). Further, the transmission control device 30 displays the display data corresponding to the dimming level to the individual operation terminal 10a corresponding to each level control terminal 20 in the order in which the transmission signal Vs is received from the level control terminal 20. Transfer (8) (10).

Although the load is the lighting load L in the above description, any load may be used as long as it controls the operation level, and the load may be blind.
