DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring and control system for centrally managing by turning on / off or dimming many indoor and outdoor lighting loads.

[0002]

2. Description of the Related Art FIG. 11 is a block diagram showing a configuration example of a conventional remote monitoring control system. Reference numeral 101 denotes a dimming terminal 103a, 103b, an on / off terminal 104, and a monitoring terminal (wall switch) 105, 106 through time division multiplex transmission of monitoring data and control data through a transmission line 102.
And dimming control and lighting of the dimming load 107.
A central control unit for controlling the light-off; 102, transmission lines for time-division multiplex transmission of monitoring data and control data;
Reference numeral 3b denotes a dimming terminal for dimming the dimming load 107 based on a control signal received from the central control device 101, and 104 denotes an AC dimming load for lighting or the like based on a control signal received from the central control device 101. On / off terminals that turn on and off when the power is turned on / off, 105 and 106 are monitoring terminals that notify the central control unit 101 of monitoring data such as the on / off state of attached switches, and 107 is a dimming terminal. Dimming terminals 103a and 103b for dimming lighting and the like, and 108 dimming terminals 103a and 103b
This is a setting device that wirelessly sets addresses and function data in the monitoring terminals 105 and 106 and the like.

In the above system, the central control unit 10
An address is set for each terminal so that 1 can control each terminal separately. Also, the monitoring terminals 105, 1
Reference numeral 06 sets the function of the attached switch and the like in addition to the address. The setting unit 108 performs such settings as addresses and functions for each terminal device. The setting unit 108 performs a setting operation by transmitting setting data wirelessly (or by wire) to each terminal device.

The communication speed between the setting unit 108 and the terminal to be set takes into consideration the case where the normal processing performed by the terminal with the central control unit 101 etc. is busy. Instead, the communication speed is fixedly set to a low communication speed that can be received by the processing device of the set terminal. However, when the set terminal enters the setting mode, the central controller 101
Since the communication with the server is temporarily stopped, the communication is not busy, and the setting data can be transmitted and received at a higher communication speed. Nevertheless, since data is transmitted and received at the slow communication speed as described above, it takes time to set the data, and the communication suspension time with the central control device 1 becomes longer, and the communication of the terminal to be set becomes longer. There was a problem that the time required to return to the system was long.

In order to avoid this problem, the setting device 10
It is sufficient to set the communication speed of 8 higher, but this means that if the terminal to be set happens to be busy, a communication error occurs, it is difficult to access the terminal to be set, and data cannot be set. There was a defect.

By the way, in the above-mentioned system, when the light-off switch 154 of the monitoring terminal 105 is pressed, the monitoring data indicating this pressing is transmitted through the transmission line 102 to the central control unit 1.
01 is transmitted. Based on the monitoring data, the central control device 101 sends, for example, a dimming load 1 to the dimming terminal 103a.
A dimming terminal 103a that receives a control signal that dims 07 at 0%, dims the dimming load 107 at 0%, and turns off (dims) the dimming load 107. . However, in this case, since the dimming load 107 performs the dimming operation, even a small amount of power is consumed, and
When there are a large number of power supplies, this power consumption cannot be ignored, and there is a problem that power is wasted.

Therefore, in order to avoid the above problem, a monitoring terminal 106 is provided, and when the light-off switch 154 of this terminal 106 is pressed, monitoring data indicating this pressing is transmitted to the central control unit 101, Central control unit 10
1 receives the monitoring data from the monitoring terminal 106 and sends a control signal for turning off the light to the on / off terminal 104. In response to this, the ON / OFF terminal device 104 turns off the AC power, cuts off the power supply to the dimming load 107, and turns off (turns off the power). In this case, the dimming load 10
7, the dimming load 107 is turned off.
Thus, power is not consumed thereafter, thereby contributing to power saving.

As described above, in the conventional remote monitoring and control system, the dimming load is controlled by the dimming control by the monitoring terminal 105.
Turning off the light 7 causes a problem that power is wasted wastefully. In order to avoid this, the monitoring terminal 10 turns off the light control load 107 by turning off the power to the light control load 107.
6 is provided, the monitoring terminals 105 and 106 are provided in the system.
This requires two types of monitoring terminals, and the system is complicated and expensive.

In an office where the remote monitoring control system is installed as described above, an air-conditioning heat exchange unit of the air-conditioning system is installed in each area where the dimming load 107 is installed. The dimming load 107 is bright and dark, and it can be checked at a glance whether or not it is turned off. Therefore, it is rare to forget to turn off the lighting. However, since the air-conditioning heat exchange unit has a small operation display unit, forgetting to turn off often occurs. However, there is a problem in that electric power is wasted and wasteful electricity bills increase.

Therefore, in order to avoid such a problem, the remote monitoring control system and the air conditioning control system are connected to the upper central monitoring panel by communication, and the central monitoring panel controls the remote monitoring control system and the air conditioning control system. Perform monitoring. As a result, there is a system in which the central monitoring panel transmits a fan coil control signal to the air conditioning control system in accordance with the lighting state of the lights to perform air conditioning control, thereby preventing the air conditioning from being forgotten to be turned off. However, such a system is possible in a large-scale building where a higher-level central monitoring panel is installed, and in small and medium-sized buildings, not only is the equipment cost expensive, but also the operation management is difficult, Many cases cannot be introduced.

[0011]

In the conventional remote monitoring and control system as described above, the dimming terminals 103a, 103
b, the communication speed between the setting unit 108 for setting data by communication to the monitoring terminals 105 and 106 and the set terminal is set to be low, so that there are few communication errors, but the data setting is slow and the There was a problem that the return of the terminal to the system was delayed. Also, when turning off the dimming load,
In a system in which dimming and extinguishing is performed only by the monitoring terminal 105, power is consumed even when extinguishing, and there is a problem that there is no power saving effect. So, to avoid this problem,
Turning off the power supply to the dimming load 107
If the monitoring terminal 106 for turning off the light is provided, two types of monitoring terminals such as the monitoring terminals 105 and 106 are required in the system, and there is a problem that the system is complicated and expensive. Further, there is a problem in that the air conditioning heat exchange units installed in various areas such as offices in which the remote monitoring and control system are installed are often forgotten to be turned off, so that electric power is wasted and wasteful electricity costs increase.

The present invention has been made to solve the above-mentioned problems, and can set data in a short time without causing a communication error. The primary objective is to provide a remote monitoring and control system that simplifies the system by turning off the light and turning off the power, and works to turn off the dimming terminal and stop the air conditioning to prevent forgetting to turn off the air conditioning. It is a second object of the present invention to provide a remote monitoring and control system capable of performing such operations.

[0013]

According to a first aspect of the present invention, there is provided a transmission line for performing time division multiplex transmission of data; a dimming load; and dimming control of the dimming load by a dimming control signal on the transmission line. A dimming terminal; a monitoring terminal for sending monitoring data such as an operation state of a switch on the transmission line; and a dimming terminal based on monitoring data sent from the monitoring terminal through the transmission line. A central control unit for transmitting a control signal to be controlled on the transmission line; a setting unit for setting data by changing the communication speed to the monitoring terminal or the dimming terminal on the way according to the busy state of the terminal; ;

With this configuration, when the monitoring terminal or the dimming terminal is busy communicating with the central controller via the transmission line or the like, the setting data is used to transfer the address data or the function data to the central control device. When setting the monitoring terminal or the dimming terminal, if the communication speed is high, the monitoring terminal or the dimming terminal cannot receive the setting request data from the setting device, a communication error occurs, and the data setting is performed. Does not shift to operation. In order to avoid this, if the communication speed is set to be low, even the busy monitoring terminal or the dimming terminal can shift to the setting operation from the setting device without a communication error. However, when setting data in the monitoring terminal or the dimming terminal that is not busy, if the communication speed is slow, the setting operation takes a long time, and the data cannot be set efficiently. Therefore, the communication speed when setting data in the monitoring terminal or the dimming terminal has an optimum speed, and furthermore, since this depends on the busy state of the monitoring terminal or the dimming terminal, If the communication speed between the setting device and the monitoring terminal device or the dimming terminal device is changed in the middle according to the busy state, data can be set efficiently, and the data setting can be performed in a short time without a communication error. Will be

The monitoring terminal or the dimming terminal according to the second aspect of the present invention, upon receiving a data setting request from the setting device, temporarily stops communication with the central control device through the transmission line. When the data setting by the setting device is completed, the communication with the central control device is restarted.

With this configuration, when the monitoring terminal or the dimming terminal receives the data setting request from the setting device, it temporarily stops communication with the central control device through the transmission line. Since the monitoring terminal or the dimming terminal can thereafter concentrate on only the data setting process, data can be transmitted / received to / from the setting device at a high speed, and the data setting can be completed in a short time. it can. Thereafter, the communication with the central control device is resumed, the monitoring terminal or the dimming terminal can return to the system in a short time, and even if the communication with the central control device is temporarily stopped, there is not much trouble. Absent.

According to the third aspect of the present invention, the communication speed is initially low and then changed to a high speed.

With this configuration, if the communication speed between the setting device and the monitoring terminal device or the dimming terminal device is low at first, even if these terminals are busy, no communication error occurs. , The setter may access the monitoring terminal or the dimming terminal and place these terminals in a setting mode. Thereafter, if the monitoring terminal or the dimming terminal delays communication with the central control device or stops the communication until the data setting is completed, these terminals are not busy. Therefore, even if the communication speed between these terminals and the setting device is increased, the setting process can be performed efficiently without a communication error, and the data setting can be completed in a short time. For this reason, the monitoring terminal or the dimming terminal can slow down the communication with the central control device, or can shorten the time during which the terminal is stopped,
The system can be returned in a short time, and there is no problem.

According to a fourth aspect of the present invention, there is provided a transmission line for time-division multiplex transmission of data; a dimming load; a dimming terminal for dimming the dimming load by a dimming control signal on the transmission line;
An on / off terminal for turning on / off the power to the dimming load by a control signal on the transmission line; a monitoring terminal for sending monitoring data such as an operation state of a switch on the transmission line; Dimming the switch function,
Or a setting device for setting any of the functions of power-off and light-off; monitoring data indicating that the dimming / light-off switch of the monitoring terminal has been pressed is sent from the monitoring terminal via the transmission line. Then, a dimming control signal for controlling the dimming terminal is sent out on the transmission line to dimming the dimming load by 0%, or a power-off switch of the monitoring terminal is turned off. When monitoring data indicating is transmitted through the transmission line, a central control device that performs control to send an off control signal for turning off the on / off terminal to the transmission line and cut off power supply to the dimming load. And;

With this configuration, when the function of the switch of the monitoring terminal is set to dimming and extinguishment by the setting device, and when this switch is pressed, the dimming and extinguishing switch is sent from the monitoring terminal. Monitoring data indicating that the button has been pressed is sent to the central controller via the transmission line.
Accordingly, the central control unit sends out a light-off control signal for controlling the light control terminal on the transmission line, so that the light control terminal dims the light control load by 0% and turns off the load. I do. However, in this case, even if the dimming load is off, a small amount of power is consumed because the dimming operation is performed. Therefore, in order to avoid this, the setting function sets the switch function of the monitoring terminal to power off and off. In this case, when the switch of the monitoring terminal is pressed, monitoring data indicating that the power off / off switch has been pressed is sent from the monitoring terminal to the central control device through the transmission line. Accordingly, the central control unit sends out a control signal for controlling the on / off terminal to be off on the transmission line, so that the on / off terminal shuts off the power supply to the dimming load and turns off the load. I do. In this case, no power is consumed and power is saved.

The change of the setting of the switch function of the monitoring terminal according to the present invention is performed by changing the address data of the switch by the setting device.

With such a configuration, the central control unit identifies the function of the monitor terminal by the address data set in the switch (usually a plurality of switches) of the monitor terminal.
Perform the corresponding control. Therefore, if the setting device sets the address data for giving the dimming / extinguishing function to the switch of the monitoring terminal device, this switch becomes dimming / extinguishing. Further, if the setting device sets address data for providing a power-off / light-off function to the switch of the monitoring terminal, this switch is used for power-off / light-off.

FIG. 2 is a perspective view showing an example of the appearance of the setting device 8 shown in FIG. A display unit 81 such as an LCD for displaying setting data and received data is arranged on an upper portion of the upper surface of the setting device 8, and an input unit 82 as an operation key group for transmitting setting data and the like is arranged below the display unit 81. . 86 is a power key. The monitoring terminal 5 is provided with switches 51 to 54, and LEDs are provided on both sides of each switch to indicate a control state result by pressing each switch.

FIG. 3 is a block diagram showing a detailed configuration example of the monitoring terminal 5 and the setting unit 8 shown in FIG. The monitoring terminal 5 includes a processing unit 31 that performs data setting processing and communication processing,
A variable communication speed infrared transmission / reception unit 32 for transmitting / receiving data to / from the setting device 8, an L disposed beside the switch

It has a power supply unit 37 for supplying the rectified voltage obtained by the rectification unit 36 to the inside of the terminal device. The setting unit 8 includes an input unit 82 for inputting data to the processing unit 83, a processing unit 83 for performing a setting process, an infrared transmission / reception unit 84 of a variable communication speed for transmitting / receiving data to / from the monitoring terminal 5, a setting unit. And a battery 85 for supplying power to the container 8.

Next, the operation of this embodiment will be described. The central controller 1 in FIG. 1 performs dimming based on the addresses set in the dimming terminals 3a and 3b, the monitoring terminals 5 and 6, and the function data set in the monitoring terminals 5 and 6. Dimming, turning off, and lighting control of the load 7 are performed. The addresses and functions described above are set by the setting unit 8 when the system is constructed or when the layout of the dimming load 7 is changed.

Here, the operation when data is set in the monitoring terminal 5 by the setting device 8 will be described with reference to FIGS.
This will be described with reference to FIG. First, when the power key 86 of the setting device 8 in FIG. 2 is turned on, power is supplied from the battery 85 in FIG. 3 to each part of the setting device 8, and the setting device 8 is activated. Thereafter, when the key of the input unit 82 is operated to transmit the setting request data, the processing unit 83 which has received the key operation creates the setting request data and transmits it to the step 20 in FIG.
At 1, the data is transmitted from the infrared transmitting / receiving section 84 to the monitoring terminal 5. When the power is initially turned on, the infrared transmitting / receiving section 84
Is set in advance to be in the slow mode, and the infrared transmitting / receiving unit 32 of the monitoring terminal 5 is also normally set in the slow mode.

When the infrared transmission / reception section 32 of the monitoring terminal 5 receives the above-mentioned setting request data in step 101, the processing section 31 creates response data indicating that the setting mode is set, and transmits this in step 102 to the infrared transmission / reception. The transmission is performed from the unit 32 to the setting unit 8, and the transmission interface 35 is controlled to temporarily stop the communication with the central control device 1 in step 103. Thereafter, the processing unit 31 switches the communication speed of the infrared transmission / reception unit 32 to the high mode in step 104.

On the other hand, when the infrared transmission / reception unit 84 of the setting unit 8 receives the response data from the monitoring terminal 5 at step 202, the processing unit 83 switches the communication speed of the infrared transmission / reception unit 84 to a high mode at step 203. . Thereafter, the processing unit 83 transmits, for example, the address data input from the input unit 82 from the infrared transmitting / receiving unit 84 to the monitoring terminal 5 in step 204. Processing unit 31 of monitoring terminal 5
After the address data received by the infrared transmitting / receiving unit 32 is stored in the internal electrically rewritable non-volatile memory or the like in step 105, response data indicating that the address setting is completed is created, and this is stored in step 106. Is transmitted from the infrared transmission / reception unit 32 to the setting device 8 to end the processing.

On the other hand, when the infrared transmitting / receiving section 84 of the setting device 8 receives the response data from the monitoring terminal 5 in step 205, the processing section 83 ends the processing. On the other hand, when the data setting process described above is completed, the processing unit 31 of the monitoring terminal 5 immediately controls the transmission interface 35 to start communication with the central control device 1 and returns to the system. Then, the communication speed is switched to the slow mode, and the processing shifts to the normal processing operation.

Here, it is assumed that the communication speed in the slow mode is set to a speed that the processing unit 31 can sufficiently receive even if the monitoring terminal 5 is busy. The communication speed in the fast mode is the speed accepted when the processing unit 31 performs only the setting operation, that is, 10 times the communication speed in the slow mode.
It is assumed that it is set to about twice.

FIG. 5 is a timing chart showing the data transmission / reception timing between the setting device 8 and the monitoring terminal device 5 at the time of the data setting described above. First, the setting device 8 transmits the setting request data 61 to the monitoring terminal device 5 at a low communication speed. Thereafter, the response data 62 from the monitoring terminal 5 is transmitted at a low communication speed.
Is transmitted to the setting device 8. Next, the setting data 63 is transmitted from the setting device 8 to the monitoring terminal 5 at a high communication speed. Thereafter, the response data 64 is transmitted from the monitoring terminal 5 to the setting device 8 at a high communication speed. That is, the setting request data 61
The response data 62 is transmitted and received at a low speed, but the subsequent setting data 63 and response data 64 are transmitted and received at a high communication speed. The above setting operation is the same even if the terminal to be set is the monitoring terminal 6 or the dimming terminals 3a and 3b.

According to the present embodiment, the setting request data 6
1 is transmitted from the setting unit 8 at a sufficiently low communication speed even if the target terminal is busy, so that the terminal can be set to the setting mode without a communication error. In addition, once the target terminal stops communication with the central control device 1 and enters the setting mode, data communication between the setting device 8 and the target terminal is performed at a high communication speed. Can be performed in a short time, and the terminal device to be set can be returned to the system in a short time. The same effect can be obtained even if the communication between the setting device 8 and the terminal device to be set is wired.

FIG. 6 is a block diagram showing a second embodiment of the remote monitoring control system of the present invention. In this example, one type of monitoring terminal device 9 is provided which can set the dimming load 7 to dimming extinguish or power off and extinguish by setting by the setting device 8. Further, an on / off terminal 4 for turning on / off the AC power to the dimming load 7 is provided. Other configurations are the same as those of the first embodiment shown in FIG.

FIG. 7 is a plan view showing a detailed example of a switch portion of the monitoring terminal 9 shown in FIG. 91-94 is 1
These are the switches of the fourth to fourth circuits. The first circuit is an up switch for the dimming terminal, the second circuit is a stop switch for the dimming terminal, the third circuit is a down switch for the dimming terminal, and the fourth circuit is an on / off switch for the dimming terminal. Or an on / off switch of an individual or group switch for turning on / off the power to the dimming load 7 controlled by the dimming terminal 3a, and which function is set by the setting unit 8. It should be noted that on both sides of each switch are LEDs 60 indicating the state of the dimming load 7 when the switch is pressed.

Next, the operation of this embodiment will be described. When the switch 91 of the monitoring terminal 9 is pressed, data for increasing the illuminance is transmitted from the monitoring terminal 9 to the central controller 1 via the transmission line 2. Central controller 1 receiving this
Transmits the control data for increasing the illuminance to the dimming terminal 3a, so that the dimming terminal 3a controls the dimming load 7 to increase the illuminance of the load. Further, when the switch 93 of the monitoring terminal 9 is pressed, the illuminance of the dimming load 7 similarly decreases.

Here, the switch 94 of the monitoring terminal 9 is an on / off switch for the dimming terminal as described above, or an on / off switch of an individual or group switch for turning on / off the power of the dimming load 7. Is set in advance by the setting device 8 so as to have any of the functions. That is, when the setting request is transmitted from the setting device 8 to the monitoring terminal 9, the monitoring terminal 9 enters the setting mode. Then, by operating the setting device 8 and setting the address of the switch 94 to, for example, 1-4 as shown in FIG. 8, a processing unit (not shown) in the monitoring terminal 9 (corresponding to the processing unit 31 in FIG. 3) The address of the switch 94 is set to 1-4, and the address is stored and set in an electrically rewritable memory or the like. Thus, the switch 94 is a switch for dimming and extinguishing the dimming load 7 of the dimming terminal 3a and dimming and lighting. If the address of the switch 94 is set to, for example, 2-4 as shown in FIG. 8, a processing unit (not shown) in the monitoring terminal 9 sets the address of the switch 94 to 2-4, and converts this to an electrically rewritable memory or the like. And set it. Accordingly, the switch 94 is a switch for turning on and off the AC power to the dimming load 7 of the dimming terminal 3a, and turning on and off the load 7 thereafter.

The central controller 1 performs control based on the addresses set in the switches 91 to 94 of the monitoring terminal 9. That is, if the address of the switch 94 is 2-4 and the switch 94 is pressed, and the dimming load 7 of the dimming terminal 3a is lit, the central controller 1 turns on and off through the transmission line 2. By transmitting control data of a power-off instruction to the terminal device 4 and turning off the on-off terminal 4,
The supply of AC power to the dimming load 7 is cut off and turned off. When the switch 94 has an address of 1-4 and the switch 94 is depressed and the dimming load 7 of the dimming terminal 3a is turned on, the central controller 1 transmits the signal through the transmission line 2. The control data for the light-off instruction is transmitted to the light control terminal 3a, and the light control load 7 is turned off by dimming the light control load 7 by 0%.

According to the present embodiment, the switch 94 of the monitoring terminal 9 is turned on / off for the dimming terminal, or the power of the dimming load 7 controlled by the dimming terminal 3a is turned on.
Since the setting of any of the ON / OFF switches of the individual or group switches to be cut off can be changed by the setting device 8 as needed, the dimming load 7 can be dimmed and turned off by one type of monitoring terminal 9. Alternatively, a system capable of turning off and turning off the power can be constructed with an inexpensive and simple configuration. In particular, if the switch 94 is an on / off switch of an individual or group switch for turning on and off the power of the dimming load 7, no wasteful power is consumed when the dimming load 7 is turned off. effective.

FIG. 9 is a block diagram showing a third embodiment of the remote monitoring control system of the present invention. The remote monitoring control system controls the dimming terminals 3a1, 3a2 to 3c1, 3c2, the monitoring terminals 5a1, 5a2 to 5c1, 5c2 and the dimming terminals controlled by the respective dimming terminals on the transmission line 2 connected to the central controller 1. It has an optical load 7. In such a remote monitoring control system, the dimming load 7 controlled by the dimming terminals 3a1 and 3a2 is installed in the area A of the building, and the monitoring terminals 5a1 and 5a2 are installed. The same applies to the other areas B and C. The air conditioning system includes control terminals 13a to 13c connected to a transmission line 12 connected to the air conditioning control device 11, and these control terminals 13a to 13c.
The air conditioner has heat exchange units 14a, 14b, 14c for turning on and off the AC power to the fan coil. The air-conditioning heat exchange units 14a, 14b, and 14c are installed in area A, area B, and area C of the building, respectively.

Normally, the air-conditioning heat exchangers 14a, 14b, 1
4c, the control terminals 13a, 1
3b, 13c and the transmission line 12.
Here, for example, it is assumed that the air-conditioning heat exchange unit 14a in the area A is performing an air-conditioning operation, and that the dimming load 7 in the area A is lit. Thereafter, the switch of the monitoring terminal 5a1 is operated, and all the dimming loads 7 connected to the dimming terminal 3a1 are turned off.
Is operated, and all the dimming loads 7 connected to the dimming terminal 3a2 are turned off. Central control unit 1
Monitors whether all the dimming loads 7 arranged in one area are turned off, and as described above, the area A
When it is known that all the dimming loads 7 have been turned off, the air conditioning control device 11 issues a command to stop the operation of the air conditioning heat exchange unit 14a in the area A.

When the air-conditioning control unit 11 receives from the central control unit 1 a command to stop the operation of the air-conditioning heat exchanging unit 14a in the area A, the air-conditioning heat exchanging unit 14a in the area A is in operation. The coil-off instruction data is transmitted to the control terminal 13a through the transmission line 12. Control terminal 13a
Receives the fan coil off instruction data, shuts off the AC power supplied to the fan coil of the air conditioning heat exchange unit 14a, and stops the operation of the air conditioning heat exchange unit 14a.
The same applies to the air-conditioning heat exchange units 14b and 14c in other areas. When all the dimming loads 7 in those areas are turned off,
When the air-conditioning heat exchange unit in the area is operating, the central control unit 1 controls to stop the operation.

FIG. 10 is an example of a table for stopping and controlling the air conditioning heat exchange units 14a, 14b and 14c by the central controller 1, which is stored in a memory (not shown) in the central controller 1. FIG. 10A shows that none of the dimming loads 7 is turned off in the areas A, B, and C. Thereafter, when the dimming load 7 of the dimming terminal 3b2 in the area B is turned off, the CPU in the central controller 1
(Not shown) rewrites the table and
(B). From this table, area B
It can be seen that all of the dimming loads 7 are turned off, so that the central controller 1 issues a command to the air conditioning controller 11 to stop the operation of the air conditioning heat exchange unit 14b in the area B.

For example, if the operation of the air conditioning heat exchange unit 14a is stopped by the operation unit of the air conditioning heat exchange unit 14a while the dimming load 7 in the area A is lit, the air conditioning control unit 11 The operation of the air conditioning heat exchange unit 14a is stopped. Therefore, the central controller 1 performs only control to stop the operation when the dimming loads 7 in a certain area are all turned off and the air conditioning controller in this area is operating.

According to the present embodiment, when all the dimming loads 7 in a certain area are turned off and the heat exchange unit for air conditioning in this area is operating, the central control unit 1 of the remote monitoring and control system uses the air conditioning. In order to perform the control for stopping the operation of the heat exchange unit for air conditioning, the air conditioning heat exchange unit that is operating without being turned off even when there are no people in the area, such as when all the dimming loads 7 are turned off, is eliminated. Therefore, wasteful electric power can be consumed, and wasteful electricity bills can be eliminated. Further, in this example, since the remote monitoring control system and the air conditioning control system are linked, there is no need to install a central monitoring panel, and the facility cost is reduced and the operation cost is reduced, thereby obtaining the above effects. Can be.

In the above embodiment, the central control unit 1 of the remote monitoring and control system controls the operation of the air-conditioning heat exchange unit which is forgotten to be turned off via the air-conditioning control unit 11 of the air-conditioning control system. The same effect can be obtained even if the central control device 1 also serves as the air conditioning control device 11.

As described above, according to the first aspect of the present invention, the monitoring terminal or the dimming terminal changes the data by changing the communication speed halfway according to the busy state of these terminals. Data setting can be performed in a short time without a communication error.

According to the second aspect of the present invention, since the monitoring terminal or the dimming terminal temporarily stops communication with the central control device during data setting, data can be set at a high communication speed during this time. Since the data can be set in a short time and the communication between the terminal and the central control device can be restarted in a short time, the system can be returned to the terminal in a short time.

According to the third aspect of the invention, since the communication speed between the monitoring terminal or the dimming terminal and the setting device is initially reduced, a communication error hardly occurs, and thereafter, the communication speed is increased. Therefore, data can be set in a short time.

According to the fourth aspect of the present invention, the setting device provides
By setting the switch of the monitoring terminal to either dimming off or power off, the dimming load can be dimmed by 0% to turn off the load, or the dimming load can be turned off. Turning off the lights with a power saving effect
This can be done with different types of monitoring terminals, and can increase the flexibility of the system without making the system complicated or expensive.

According to the fifth aspect of the present invention, by changing the switch function of the monitoring terminal by changing the address data, the function of the switch can be easily set.
