Abstract

<P>PROBLEM TO BE SOLVED: To eliminate the need of connecting wires by using batteries for all the electric sources of various types of sensors and remote controllers that are employed. <P>SOLUTION: Radio signals are sustainably sent from sensors to perform monitoring. In addition, portable type remote controllers are employed to control the whole of a system. A controller that has received abnormal signals from each sensor and remote controller makes a call to a predesignated telephone number to report the abnormal condition. At this time, the controller checks if the signals received have been sent from an apparatus in which each sensor and remote controller are registered or not to prevent any malfunction of the apparatus. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention employs Microchip KEELOQ code hopping technology.

All sensors use batteries, eliminating wiring work and simplifying installation.

All communication methods between the sensor, remote control and control unit are performed wirelessly.

A switch for confirming whether the telephone line for reporting can be used is provided.

I wanted to prevent the malfunction of the control unit when using a variety of sensors wirelessly.

There is no sensing function for telephone line disconnection.

Therefore, this invention eliminates malfunctions even when multiple machines are used together by adopting code hopping technology. This can be resolved by checking the code between the control unit and each sensor and remote control at the initial setting.

Added line disconnection detection function to the control unit.

wrap up

the purpose

All security sensors and remote controls that use batteries use batteries and require no wiring. The sensors continuously emit radio signals for monitoring. The entire system is controlled by a portable remote control.

Constitution

As shown in Figure 3, the control unit, each sensor, and the remote control communicate wirelessly, and in case of an emergency, up to eight pre-recorded messages are automatically sent to the specified phone number.

The invention's effect

As is apparent from the above, the present invention installs this device to quickly detect crimes, fires, abnormalities in the elderly at home by emergency calls of sensors and remote controllers, and to sound a siren and to a designated telephone number. Make emergency calls to minimize disasters.

Fig. 2 shows an example of the sensor, A is a door sensor that detects the opening and closing of the door, B is a window sensor that detects intruders from the window with infrared rays, and C is a smoke detector. Detects smoke from fire, etc. D is an infrared sensor that detects human intrusion.

When each sensor detects an abnormality, it will transmit to the control unit wirelessly, and the control unit will automatically notify the phone number registered in advance.

Abnormality notifications can be sent manually to the control unit not only from the sensor but also from a portable remote controller, allowing emergency notifications from the control unit. This is possible by operating the buttons on the remote control when it occurs, and is considered a means of emergency call.

Block diagram of control unit (main body) according to the present invention

This control unit has four switches A to D. Switch A records the contents of the report while pressing this switch. The recording time at this time is about 15 seconds. Switch B is a reset switch. By pressing this switch, the registered ID of each sensor, remote control, etc., will be deleted. Switch C is a setting switch. Used when registering the phone number of the switch D is a switch that detects whether the telephone line is disconnected or not.
The above four switches are mounted on the control unit. Example of the product of the present invention

As mentioned above, the diagram of A to E device is shown. A is a door opening / closing sensor with a magnet, B is an infrared sensor with a narrow detection range, installed on a window, etc. C is a smoke detection device, detects smoke when a fire occurs, D is general Detects human intrusion with a simple infrared sensor, E receives the radio transmitted when each sensor detects an abnormality in the control unit and makes an emergency call to the specified contact while sounding a siren . It is a simple block diagram of the product of the present invention

As shown in the figure, all sensors and remote controllers communicate with the control unit wirelessly, and the control unit reports to a general phone or mobile phone using a general line.

Claims (1)

  An emergency call system that uses Microchip's KEELOQ code hopping technology in the control unit to eliminate malfunctions of the same model and control the control unit as a portable remote control.
