Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the operation, automation, and energy saving of the main controller in Baum control devices i, 7.

Conventional configuration and its problems In the main controller of a home control device that operates terminal equipment and monitors the status continuously 24 hours a day, regardless of whether it is operated by a human or not, the main controller main controller body side power , is always energized, so either a separate switch from the main controller is provided to turn it on and off during operation, or the power for the CRT display, which serves as the display section, is always energized without a separate switch. Ta.

In this configuration, in the former case where a separate switch is provided, the CRT display only needs to be turned on during operation, so a method was used in which the power switch of the CRT display was turned on and off each time the operation was performed. . However, this method is not easy to use and is also the cause of forgetting to turn off the power switch of the CRT display. The latter, which is not provided with a switch and is kept energized at all times, is disadvantageous in terms of the lifespan of the CRT display and energy conservation. In addition, the method of installing a detection means and immediately turning on the power of the display means when a person is detected means that the detection section will detect the person just by being in front of the person or the main controller. The CRT display turned on and crashed.

Furthermore, when any key is pressed without providing a detection means,
The method of turning on the display means had the problem that unless a preheating current was constantly flowing through the tube, it would take time for the display to appear due to the time required by the heat amplifier of the cathode ray tube.

OBJECTS OF THE INVENTION The present invention solves such conventional problems by automatically turning on the display means when the main controller is operated, and turning it off when the main controller is not operated or after the operation is completed.
The aim is to improve the operability of the main controller and save energy.

Structure of the Invention In order to achieve this object, the final IJ'I performs the exchange of take between the terminal device and the main controller.
tA means, a key manual input means, a CRT display serving as a display section, a display control section for storing the display contents and outputting the displayed contents as a video to the CRT display; a display means consisting of a power supply control section that controls the power supply of each part; a detection means that detects whether a person is present in front of the main controller;
The main controller consists of a memory consisting of OM, RAM
Immediately, the power supply control section of the display means causes a preheating current to flow through the cathode ray tube of the CRT display, and at the same time turns on the power supply of the display control section and the display memory. Further, in order to immediately display the display contents, the display take is transferred to the display memory in advance. When any key being detected is pressed, the CRT tape serving as the display section is turned on. As a result, the display contents are displayed on the CRT display, and the main controller can be operated from now on. When the operation is completed or interrupted and the presence of a person is not detected by the detection means for a certain period of time, the power supply control section of the display means turns off the power to the display section, display control section, and display memory. Key capture by the input means stops.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In FIG. 1, a main controller 1 and a terminal controller 2 are connected to a common signal line 4 via a communication means 3. The communication means 3 each have a different address, and perform bucket disassembly, generation, and error checking based on communication vision (pro-drill), and mutually send and receive takes via the signal line 4. (The S line 4) has a parallel structure, and direct transmission and reception of take is possible between any communication means 30. The terminal device 5 exchanges operation details and status information with the terminal controller 2. The take transmitted from the main controller 1 to the terminal device 5 is converted into a bucket signal by the communication means 3 in the main controller 1 and transmitted to the signal line 4. The packet signal is transmitted to the destination terminal controller 2, and the communication means CNC receives and disassembles the bucket signal when the addresses match. This disassembled signal is then transmitted to the terminal device 5. Status information from the terminal device 5 is also transmitted to the main controller 1 by similar means.

Next, a circuit block diagram of the main controller 10 is shown in FIG. In the figure, a communication means 3, a detection means 9, a display means 12, an input means 15, a memory 8 and a CPU 7 are connected via an internal bus 6.

The CPU 7 controls each means based on a program stored in the memory 8. The detection means 9 includes a detection unit 1 that includes a sensor that detects the presence of an object.
0 and a detection control section 11.

The detection control unit 11 inputs the confidence of the detection unit 10, and when it detects an object or a human being, immediately sends a detection (l) to the CPU 7.
:'i is output, and continues to be output even if it is not detected continuously for a certain period of time or more. The display means 12 includes a display section 13 made of a CRT display, a display control section 15, a display memory 14, and a power supply control section 16. The display control unit 15 inputs the display content take for one screen from the memory 8 through the CPU 7 controller, and inputs the display content take from the memory 8 to the display memory 1.
4, the IJ converts the display content in the display memo 4, which is a digital take, into a video image and outputs it to the display section 13. The power supply control unit 16 includes a CPU 7
Based on the finger of the table/J-ma part 13, the breathing current of the plaque tube of the CRT display, which is the CR which becomes the display part 13.
Turns on and off the power of the T display, display control unit 15, and display memory 14. The input means 17 includes a key matrix 18, and an input control section 19 that includes an encoder and a decoder and performs key scanning. FIG. 3 shows a front view of the operation panel of the main controller, and FIG. 4 shows the functional gear R#2o and the room key group 21. In these figures, a CR which is a display section 13 is shown on the operation panel surface.
A sensor for detecting an object serving as a T display and a detection unit 10, a group of function keys 20 for selecting the terminal device 5 by function,
A group of room keys 21 to be selected for each room, a group of function keys 20,
Operation keys 1 for inputting operation details such as temperature, time, operation mode, etc. to the terminal device 5 selected by the room key group 21;
A21 is provided.

In the above configuration, the operation of each part will be explained based on an operation example of the main controller 1 to the roller 1. When a person enters the detection range of the detection unit 1o of the operation panel of the main controller 1, the detection unit 1o detects the object, and the detection control unit 11
If it detects that the object is a human, a detection value - ri is immediately output to the CPU 7.

CPU 7r/i, upon receiving the detection signal, the power supply control unit 1
6, an instruction is issued to cause a breech current to flow through the plaque tube of the CRT display, which will become the display section 13, and to turn on the power to the display control section 15 and the display memory 14. Further, predetermined display contents are transferred in advance from the memory 8 to the display memory 14, and the input control section 19 is caused to scan the key matrix 18 to start storing the keys.

When any key is pressed during detection, the display section 13
The RT display is turned on to display predetermined display contents recorded and enlarged in the display memory 14 in advance. After that, the main controller can be operated. For example, if a terminal device 5 with a function consisting of a room consisting of a function key group 20 and a room key group 21 is selected, the current status information of the terminal device 5 is input to the main controller 1 via the communication means 3. , are displayed on the display unit 13 in characters or graphic ink. Next, if you want to perform some operation on the terminal device 5, use the operation key group 20 to select the terminal device 5.

Input operations for setting values such as heating operation at a set temperature of 25° C. from 1: to 00 are performed according to the operating procedure shown on the display unit 13. Through the above operations, the operation of the terminal device 5,
Reservations for operations are made, and when the time comes, a take commanding an operation is sent and received via the communication means 3. When the operation is completed or interrupted and the person disappears from the curved surface of the operation panel and goes out of the detection range, and the detection unit 10 does not detect the presence of the person for a certain period of time or more, the detection control unit 11 Stop outputting the detection signal. When the detection signal stops, the CPU 7 instructs the power supply control section 16 to turn off the currents of the display section 13, display control section 15, and display memory 14, and stops the scanning of the key matrix 18 by the input control section 19.

As described above, the power on and off of the display means 12 is automated, the operability is improved, and it is possible to prevent forgetting to turn off the CRT tape. Furthermore, since the power to the display means is turned off except during operation, energy savings can also be achieved.

As described above, the home control device of the present invention is provided with a detection means for detecting the presence of a person, and immediately after the detection, the display control unit and the display memory are powered on, and the display content is stored in the display memory. At the same time as preparation □, a preheating current is applied to the gratin tube of the CRT display that will become the display section. Furthermore, the inputting of the keys of the input means is started. Here, when an arbitrary key is pressed, the CRT display is turned on, and the display contents prepared in advance are immediately displayed, and the main controller can be operated thereafter. If no human being is detected for a certain period of time, the power to the CRT display, display control unit, and display memory is turned off, and the key input of the input means is stopped. With the above configuration, the CRT display, which is the display section, can be automatically turned on only when an operation is performed, and turned off after the operation is completed, without having to provide a specific switch.
No more forgetting to turn off the T-display. Furthermore, in order to detect a person before the key input operation is performed, the display means, which had been turned off, is placed on standby during operation (f, I) (in the gratin tube of the CRT display). A preheating current is applied to heat up the display, the display control unit and the display memory are turned on, and the display contents are prepared in the display memory. Even if it is not displayed, it can be displayed immediately during operation, so the main controller can save energy without impairing operability.
