The display 10 displays various kinds of information, and includes a plurality of sensor storage units 7, 7 ... For storing the sensors 1, 1.
And a load display section 12 corresponding to one load storage section 8 for storing the load 20. Specifically, this display 10 is formed by a touch panel 13 as shown in FIG. The touch panel 13 is capable of inputting predetermined items by touching a menu displayed on the screen with a finger, a pen, or the like, and can display various kinds of information.This input uses, for example, electromagnetic induction or infrared rays. It can be realized by reading the coordinates on the screen. This touch panel 13 is a name of a specific load 20 stored in the load storage unit 8, for example, "load 1 ventilation fan" at the upper part and all the sensors stored at the lower part in the sensor storage units 7, 7 ... Characters such as "1. temperature sensor", "2. flame sensor", "3. kettle sensor" which are names of 1, 1 ...

The operating device 14 includes sensors 1, 1 ... And loads 20, 20.
A touch panel that outputs a memory instruction release signal for setting the correspondence with the setting device 15 and is also the display device 10.
When a character such as “1. Temperature sensor”, “2. Flame sensor”, “3. Smoke sensor”, etc. of 13 is touched with a finger or the like, a memory instruction release signal for the sensor 1 is output to the setter 15.

The setting device 15 sets the load 20 in a corresponding relationship that operates in association with the detection signal of each sensor 1 based on the memory instruction release signal from the operation device 14. The setting result is stored in the memory. It is sent to and stored in the setting storage unit 9 of the device 6.

Further, in the touch panel 13, 13a is a page feed symbol, and when the page feed symbol 13a is touched with a finger or the like, the display 4 displays a load 20 different from the load 20 displayed on the load display section 12.

The reference value setting storage means 16 includes sensors 1, 1, ...
The operation reference value of the detection signal is set, which is also set on the touch panel 13. This operation reference value is the lower limit value of the detection signal that operates the load 20 that has a corresponding relationship with the sensor 1.Specifically, the sensor 1 is a temperature sensor that uses a thermistor and operates the ventilation fan that is the load 20. In this case, the lower limit current value at which the ventilation fan is to be operated is set as the operation reference value. Further, in the case of the smoke sensor, the reference value becomes 0 when the ventilation fan is operated when the detection signal is output. This setting is performed on the touch panel 13 as with the correspondence setting storage means 4. In this case, the screen of the touch panel 13 displays, for example, an operation reference value whose value is slightly different from the type of the sensor 1, and a finger or the like touches where the operation reference value to be set is displayed.
The operation reference value is set for the sensor 1. Note that the operation reference value is set as a value that is the detection signal of each sensor 1, 1 ... As it is, if it is difficult to understand with the current value (ampere), it is displayed with a value that is easy to understand using the conversion means, for example, temperature (° C). It is also possible to do so. Further, the reference value setting storage means 16 also stores the set operation reference value in the RAM or the like and outputs the reference value to the comparison means 17.

Output to the output means 18.

The output means 18 discriminates, based on the actuation signal of the comparison means 17, the load 20 having a correspondence relationship with the sensor 1 which has output the detection signal from the storage 6 of the correspondence setting storage means 4,
The output signal is output to the power supply control means 19 connected to the load 20.

Next, the operation of this load control system will be described with reference to the flowchart of FIG. First,
Install the sensors 1, 1 ... at the location you want to detect, such as the ceiling of the room, according to the type of each sensor, and input them to the controller 2.

In this state, the correspondence setting storage means
4 sets and stores the correspondence between the sensors 1, 1 ... And the loads 20, 20. First, the discriminator 5 of the correspondence setting storage means 4
... determine which sensors 1, 1 ... and loads 20, 20, ... are connected by the signals of the input means 2 and the output means 9, and the determined result is the sensor storage section 7, 7 of the storage device 6. ... and the load storage section 8,8. Display of touch panel 13
10 is in the load display section 12 when the information is obtained from the storage unit 1
The load 20 is displayed on the sensor display unit 11 for all types of sensors 1, 1 ... Connected to the input means 3. Next, on the operating device 14, by touching with a finger or the like the name of the sensor 1, 1 ... for which the corresponding relationship with the load 20 displayed on the load display section 12 is to be set, the memory instruction release signal for that sensor 1 is set. Sent to the device 15, the setter 15 detects the sensor 1,1 ...
The correspondence relationship of 0 ..., That is, which load 20 is operated by the detection signal of which sensor 1 is set, and is transmitted to and stored in the setting storage unit 9 of the storage device 6. Repeat this operation to select all the sensors 1, 1 ... for which you want to set the corresponding relationship to the load 20 displayed on the load display unit 12, and when setting of one load 20 is complete, touch the page feed symbol 13a. The other load 20 is displayed on the load display unit 12, and the corresponding relationship of the load 20 is set,
It is sent to and stored in the setting storage unit 9 of the storage device 6.

Further, in the reference value setting storage means 16, each sensor is
Set the operation reference value of the detection signal of 1,1 .... This can also be set by operating the touch panel 13. When the setting in the operation reference value setting storage means 7 is completed, the initial setting is completed.

When the initial setting is completed, the comparison means 17 sequentially inputs the detection signals of the sensors 1, 1 ... Input by the input means 3 and compares them with the operation reference values set by the reference value setting storage means 16, When the detection signal reaches the operation reference value, the operation signal including the sensor specifying signal of the sensor 1 is transmitted to the output means 18. The output means 18 controls the power supply control means 19 connected to the load 20 corresponding to the sensor 1 that has output the detection signal that has reached the operation reference value based on the operation signal, to the storage device 6 of the correspondence setting storage means 4. It discriminates from the information in the setting storage section 9 and sends an output signal to the power supply control means 19. The power supply control means 19 controls energization of the load 20 connected thereto based on the output signal.

This is the correspondence between the sensors 1, 1 ... And the loads 20, 20 ...
Since it is possible to set the operation reference value of the detection signal, the setting state can be easily understood, so that the setting can be performed in a short time and erroneous setting can be suppressed.

Although the power supply control means has been described as one for connecting or disconnecting the electric circuit, a plurality of operation reference values of the detection signal of one sensor are set and the power supply control means is set according to the level of the detection signal. The amount of current may be controlled.
By doing so, more comfortable load control can be performed, such as changing the load capacity, for example, the rotation speed of the ventilation fan. Further, the reference value setting storage means sets the lower limit value of the detection signal, the comparison means detects whether or not the detection signal reaches the operation reference value, and when it reaches, outputs the operation signal to the output means. Depending on the type of sensor, the actuation signal may be output to the output means when the detection signal becomes equal to or lower than the upper limit value.

Further, it is not necessary to associate all the sensors with the loads, and it is possible to operate the loads without interlocking with the sensors. Further, although the touch panel is used for the setting in the correspondence setting storage means and the reference value setting storage means, the touch panel may be used for setting only one of them. Further, the discriminator of the correspondence relationship setting storage means discriminates what kind of sensor or load is connected based on the signals from the input means and the output means.
All may be input using a touch panel, key switches, or the like. Further, in the correspondence setting storage means, the display unit and the operating unit are shared by the touch panel, but they may be separately provided without being combined, and the display unit is a liquid crystal and the operating unit is a combination such as a key switch. Is also possible.
