Abstract

PURPOSE:To improve the operability of a main controller and to prevent power- off of a CRT display from being forgotten by turning on automatically the power source of the CRT display as a display part only when the main controller is operated and turning off automatically this power source when the main controller is not operated. CONSTITUTION:When a detector 9 of a main controller 1 detects a person, the detector 9 outputs a detection signal to a CPU7. Then, the CPU7 turns on the power source of the CRT in a display part 13 and scans a key matrix 16 by an input control part 17 to start the key input. When a password consisting of a combination of an operation key group 20 is inputted and coincides with a prescribed password, prescribed data is transmitted to a display control part 14. The current state of a terminal equipment in a certain room is displayed on the display part 13 by a function key group 18 and a room key group 19, and the terminal equipment is operated in accordance with displayed operation procedures. Further, when the detector 9 does not detect persons, the power source of the display part 13 is turned off to stop scanning of the matrix 16.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to a system for independently controlling the operation of a main controller in a home control device.

Conventional Mura 4-Sei and Its Problems In the main controller of a home control device that operates terminal equipment and monitors its status continuously 24 hours a day, regardless of whether it is operated by a human or not, the power supply on the main controller body side is always on. In order to keep the power energized, the CR that serves as the display section
The power supply for the T-display has either been provided with a switch separate from the main controller to turn it on and off during operation, or kept energized at all times without providing a separate switch.

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 of turning the power switch of the CRT display on and off each time the operation is performed has been included. However, this method was not easy to use and caused users to forget to press the power switch on the CRT display. The latter, which does not have a switch and is kept energized all the time, is a CRT.
This was disadvantageous in terms of display life and energy conservation. In addition, a detection means was provided to detect a human being, and in all cases where a human being was detected, the power to the CRT display was turned on, allowing the main controller to be operated unconditionally.

Therefore, even when the CRT display is not in its intended use, the CRT display remains on and the main controller can be operated, making it vulnerable to mischief by children and the like.

Invention No. 1, Objective No. 1, solves the problems of the prior art, and is capable of automatically turning on the CRT display, which is the display section, only when the main controller is operated, and turning it off when the main controller is not operated. By doing this, we can improve the operability of the main controller, prevent people from forgetting to turn off the CRT display, and prevent mischief operations.

Structure of the Invention In order to achieve the first objective, the present invention is to achieve the following points: 7, a means for manually inputting keys, a display means using a CRT display as a display section, a detection means for detecting whether there is a person in front of the main controller, and a software password setting mode. 7- How to set up the code,
Alternatively, a password setting means can be used to set the password using hardware, and each method can be configured using
If a person enters the detection range on the front of the main controller, it will immediately turn on the current of the CRT display and start scanning the keys, and the password set during the detection will be displayed on the key. When the main controller is manually operated, the subsequent operation of the main controller is performed as 'iIJ'.

When the operation is completed or interrupted and the detection means continues to detect the presence of a person for a certain period of time, the CRT display's N source is automatically turned off and key scanning is stopped. It is done.
