Abstract

PROBLEM TO BE SOLVED: To provide a microcomputer type control system that electrically detects door opening/closing of a toilet, analyzes its signal with a computer, controls lighting and an air fan of the toilet, when an abnormal situation occurs, issues a warning, and makes phone notification as necessary.SOLUTION: A microcomputer type control system: electrically detects opening/closing of a door; controls lighting by analyzing the detection with a computer; prompts a toilet user to surely close the door during use and surely close the door after use; when the prompt is not observed, regards the situation as an abnormal state occurrence after a certain period of time lapses; and issues a warning and automatically operates a built-in mobile phone by adding a drive box so as to be able to notify a third party of the situation. In addition, even when the toilet has not used over a certain period of time, the control system regards the situation as another abnormal state occurrence and performs similar operations.

Description

  This system electrically detects the opening and closing of the toilet door, analyzes the signal with a computer, controls the toilet lighting and ventilating fan, and if necessary, sounds an alarm or makes a telephone call when an abnormal situation occurs. It is something to do.

This system comprises a main body integrated with a light bulb, a door sensor , and a drive box , and realizes the function [0001].

The drive box is a device that receives a signal from the main body, drives a ventilation fan, sounds an alarm buzzer, and reports an abnormal situation to a third party by a built-in mobile phone , microcomputer board, and automatic push button mechanism . is there. (See Figure 1)

  The door sensor uses a function of sticking a one-yen coin-sized magnet piece to the door and detecting that the door is closed with a proximity switch attached to the door frame.

  In an environment where the function of [0004] cannot be used (when the door has a backlash, a sliding door, a curtain, or the like), the light emitted from the light emitting LED is reflected on the door as a door sensor. A reflective optical sensor module that detects the opening and closing of the door by returning to the light receiver is used.

  The drive box sounds an alarm buzzer and uses a function of automatically making a call using a mobile phone installed therein, a microcomputer board that operates the mobile phone, and an automatic push button mechanism.

  The mobile phone has a function of registering a phone number with a one-touch key and making a call with a simple operation. If the other party responds, a function that allows a built-in microphone to hear an alarm buzzer is used. . (See Figure 3)

Conventional toilet lighting systems mainly use human sensors and timers, which are a type of pyroelectric sensor, and when a sensor is installed at the entrance of the toilet, the light is turned on just by approaching it. May end up.

Even if the presence sensor is installed in the toilet, it cannot detect people who are still in the toilet or who cannot move, so these people use the toilet for a long time. If an abnormal situation occurs, such as when the light turns off or the user becomes unable to move due to a seizure, it is analyzed and recognized by a computer, an alarm is sounded, and a telephone call is made I can't.
It is not possible to analyze and recognize the alarm, sound an alarm, or make a phone call.

The door sensor alone cannot recognize a state where the toilet has not been used for a long period of time .

  Toilet users always use the doors closed, so the lights will not turn off while the toilet is being used except during a power outage. (Refer to [Claim 3])

  Because it is controlled by opening and closing the door, the lighting inside the toilet will not light up if you just approach the entrance of the toilet from the outside. (Refer to [Claim 1])

  Since the microcomputer analyzes the state where the door is left open and blinks the light for warning, it turns off after a certain period of time, so the light will not remain on. (See [Claim 3] and [Claim 4])

  In response to a ventilation fan drive signal from the main body to the drive box, the ventilation fan can be turned on for a certain period of time during and after use of the toilet.

  An alarm buzzer can be sounded in response to an abnormal occurrence signal from the main body to the drive box. (See [Claim 5] and [Claim 6])

  Upon receiving an abnormal event occurrence signal from the main unit to the drive box, the mobile phone, built-in microcomputer board and automatic push button mechanism call a preset telephone number to notify the third party of the abnormal event occurrence. can do. (See [Claim 5] and [Claim 6])

Block diagram of the system The system consists of a main body integrated with the light bulb, a door sensor connected to it, a drive box, a ventilation fan, and a buzzer that can be installed by removing the existing light bulb for toilet lighting. Block diagram of the main unit The main unit is supplied with AC100V power from the existing lamp socket, generates DC5V power for the microcomputer, receives the input signal from the door sensor, controls the light bulb for lighting by the microcomputer, and drives the ventilation fan Signals and abnormal situation occurrence signals are output to the drive box. Drive box block diagram The drive box is provided in the following four specifications A, B, C, and D, and these functions can be used as required. A. Only the ventilation fan control is performed, and the ventilation fan for AC100V is driven via a relay in response to a ventilation fan drive signal from the main body. B. Only the alarm buzzer is sounded. Upon receiving an abnormal state occurrence signal from the main body, the AC 100V buzzer is driven via a relay. C. Those having the specifications of A and B It is equipped with a mobile phone and its charger, a control microcomputer board, an automatic push button mechanism, and a DC5V power supply, and can notify a third party of the occurrence of an abnormal situation by telephone.

Claims (6)

A device that automatically detects the opening and closing of the toilet door and computer analyzes it with a microcomputer to control the toilet lighting , drive the ventilation fan, sound an alarm, and automatically call a third party. A method of recognizing the following states A, B, C, and D from the opening and closing of the door and the lighting control.
A. Initial state : The door is closed and the light is turned off.
B. During the use of the toilet: from the time the door is opened (for the first time to use the toilet) to the next time it is closed, until it is opened again (for going out after adding a service), and the second time it is closed State between.
C. Open the first door : (The first time you try to use the toilet) The door is left open and cannot be closed.
D. Second door open : The door is open and unclosed (again, after trying to get out).   When the first door is left open for a certain short time (usually about 10 seconds), the light is flashed several times to alert the toilet user and the door is closed during that time The lamp is turned on when it is determined that the toilet is in use, and if it is not closed after that, it automatically turns off, prompting the toilet user to always close the door during use, and lighting when not in use. A way to keep it from sticking.   Similarly, when the second door has been left open for a certain short time (usually about 10 seconds), the light is flashed several times and closed during that time to alert the toilet user. When the toilet is not in use, it is urged to always close the door after use by turning off the light and automatically turning off if the door does not close afterwards. A way to keep the lights on.   A method of issuing an alarm by determining that an abnormal situation has occurred when the states B, C, and D of [Claim 2] continue for a certain period of time (usually about 30 minutes).   A method of issuing an alarm by determining that an abnormal situation has occurred when the door has not been opened and closed for a certain period (usually about one day).
