Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method for registering a code required when switching the system from a warning mode to a release mode in a home security system.

<Prior Art> In a home security system, if the alert state or alarm state is easily canceled by an outsider, the mechanism cannot be maintained. Therefore, if a code is registered in advance when the system is put into the alert state, that is, when the system is placed in alert mode, the system cannot be changed from alert mode to release mode and the alarm sound cannot be stopped without inputting that code. It has been done. However, in the conventional method,
In the case of numerical codes, etc., the code must be input every time the user switches from alarm mode to release mode, which is not only difficult for users to use, but also difficult for children and the elderly to operate. There were drawbacks.

<Object of the Invention> An object of the present invention is to eliminate the drawbacks of the above-mentioned prior art and provide a code and registration method that can be easily used in a home security system.

<Structure of the Invention> The present invention has a warning mode and a release mode. During the warning mode, abnormalities such as window opening/closing transmitted from various parts of the house are processed by a central controller and an alarm is issued. This method is also used in a home security system that can switch from a warning mode to a release mode using a mode changeover switch, and is a method for pre-registering a code necessary for switching from the warning mode to a release mode, in which each digit is 0 to 0. An in-home security system characterized in that a code is formed by a combination of multiple digit numbers consisting of any one of the numbers 9, and a predetermined specific combination of each number combination is not coded. This is a cryptographic registration method in

<Example> Fig. 1 is a block diagram of an in-house security system in which the code registration method of the present invention is used, and Fig. 2 is a block diagram of the main FIiJFI! of the operation panel of the central controller. J. FIG. 3 is a flowchart showing the operation of canceling the warning mode.

For example, a fire transmitter E that outputs a signal that does not indicate a fire, a large i transmitter F that outputs a signal that does not indicate an intrusion, etc.
A gas leak transmitter G that outputs a signal indicating a gas leak, and other transmitters that transmit various abnormalities are installed, and each transmitter has a sensor, and when an abnormality is detected, each transmitter It sends a weak radio wave to the central controller A along with the code assigned to it. Central controller A is CI) U and ROM.

A microphone and processor consisting of RAM memory, an interface for input/output equipment, a receiver that amplifies and detects radio waves received by the antenna and inputs the signals, and an abnormality indicator lamp K that displays the abnormal state and type of abnormality.

An alarm device that emits a 1F alarm such as a buzzer to household members, a stop switch M that turns off the abnormality indicator lamp and stops the alarm sound, and a mode switch 7-chi N that switches the 11-equipment system between warning mode and release mode. , and its display run 10
The input switch 1) has the functions of setting the time and registering the number 111), and a display section Q thereof.

When a radio wave is received from the transmitter, it is converted into a logic signal and then decoded by a microprocessor, and when the security system is in alert mode, it lights up the indicator lamp K corresponding to the abnormality and sounds an alarm. . In addition, central controller A outputs a signal to the power line,
Sub-controller B receives the signal and does not sound the same type of alarm as central controller A, and if necessary, central controller A drives outdoor bell C or doorbell D to emit an alarm. It doesn't ring. On the other hand, when the security system is in the release mode, no abnormality indicator lamp or alarm sound is emitted even if a window is opened. To explain the registration of a cipher, the central controller A has a storage unit for registering the cipher, a judgment circuit that judges whether the registered cipher is a ``no cipher'' cipher, and an input signal. A judgment-1 path is provided to determine whether the code matches the registered code, and the code is formed by a combination of a plurality of digits, each digit of which is one of the numbers 0 to 9.

For example, if the code is composed of three digit numbers and you want to register number 110 (123), first press the code registration switch P of the input switch P, then press the number keys 1, 2, 3.
If you press in this order, the display on the display Q will change from the time display to the code r.
Display 123J. Then, when the code registration switch P1 is further pressed, the code (123) is written as 1. Registered in the α section. If you switch the mode to alert mode in this state, you will not be able to change from alert mode to release mode 1 or stop the alarm sound unless you input the code (123) before operating the swifts N and L. . - F. In the present invention, a specific combination of numerical values, for example (000), is defined as a "no code" code. When this code (000) is registered as a code in the same manner as described above, (000) is registered in the storage unit, but in reality it is only registered as "no code". Therefore, if the alarm mode is entered in this state, it can be canceled by directly switching the mode switch N.

However, if you enter a number other than (000) as the code number at this time, you will not be able to enter the unlocked state. To further explain the process according to the flowchart in Fig. 3, when the mode changeover switch N is switched when the mode is currently in alert mode, it is first determined based on the signal whether or not a code was entered manually at the time of switching, and the code is input. If so, it is determined whether the cipher matches an already registered cipher, and if they match, the alert mode is canceled. If they do not match, it will not be canceled and the alert mode will continue. On the other hand, if no code is input when switching modes, it is determined whether the already registered code is (000), that is, "no code", and if it is (000), alert mode 1' is canceled. .

If it is not (000), the alert mode continues. Note that the cipher can be changed while in unlock mode.

Effects〉 The present invention has the above-described configuration, and when registering cryptography, “
Since we have set up a "no code" number, the security system can be used with or without a code, so it can be used freely depending on the situation, regardless of age or gender. .

Claims (1)

[Claims] It has a warning mode and a release mode. During the warning mode, the central controller processes abnormalities such as window opening/closing transmitted from various parts of the house and issues an alarm, and the mode changeover switch switches from the warning mode to the release mode. This method is used in a switchable home security system and registers in advance a code necessary to switch from the alert mode to the release mode, the code being a multi-digit code in which each digit is a number from 0 to 9. A method for registering a code in a home security system, characterized in that a code is formed by a combination of numbers, and a predetermined specific combination of each number combination is not coded.
