Storage unit, a transmission unit that converts a code read from the storage unit into a required high-frequency signal according to a signal from the security detection unit, and sends the high-frequency signal, and a first control unit that controls the security detection unit, the storage unit, and the transmission unit. A security detecting means, a receiving section for receiving and demodulating a high frequency signal from the security detecting means, a memory section for storing a security signal corresponding to each code, and a signal for passing through the receiving section from the memory section. A discriminating section for discriminating a security signal corresponding to the read data, an alarm section for outputting an alarm based on the signal from the discriminating section; Shin unit, a memory unit, there is provided a cordless security device constructed in the security alarm means consisting of a second control unit for controlling the judgment unit and the alarm unit.

[0005]

With the above construction, in the cordless security device according to the present invention, when an abnormality such as a fire, a gas leak, or crime prevention occurs, the code indicating the cause and the location of the abnormality is a high frequency signal for a cordless telephone. Is converted to and sent. The high frequency signal is received by the base unit of the cordless telephone, the code is demodulated, the corresponding security signal is determined, and the required alarm is output.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cordless security device according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram of essential parts of an embodiment of a cordless security device according to the present invention. In the figure, A is security detection means and B is security warning means. First, the security detection means A is provided, for example, at a location where a fire or gas leak is likely to occur, or a window or door where a suspicious person can easily enter. A security detector 1 detects a fire, gas leak, intrusion of a suspicious person, or the like, and outputs a signal. A storage unit 2 stores an identification code representing the security detection means and a code set according to the cause of the abnormality, the place where the abnormality occurred, and the like. A control unit 3 reads the identification code and the code from the storage unit 2 according to the signal from the security detection unit 1 and inputs them to the transmission unit 4. The transmitting unit 4 first confirms an empty channel, and then converts the input identification code and code into a high frequency signal defined for a cordless telephone,
It is transmitted via the antenna 5.

The security warning means B is provided, for example, in the base unit of the cordless telephone. Reference numeral 11 denotes an antenna which receives a high frequency signal for cordless telephone from the security detecting means A. A receiving unit 12 demodulates an identification code, a code and the like from a high frequency signal input via the antenna 11. A memory unit 13 stores each identification code and a security signal corresponding to each code. A discriminating unit 14 compares and discriminates the identification code extracted from the signal demodulated by the receiving unit 12 with the identification code read out from the memory unit 13, and also extracts the code from the demodulated signal and extracts it from the memory unit 13. The corresponding security signal is determined by comparing with the read data. An alarm unit 15 outputs a required alarm signal based on the security signal from the determination unit 14. A control unit 16 controls each unit of the security warning means B.

Next, the operation of the cordless security device will be described. The security detection unit 1 includes, for example, a fire sensor such as a smoke sensor or a heat sensor, a gas leak sensor, a glass breakage sensor (detecting a sound such as glass breaking) provided in a window, or a door opening sensor provided in a door or the like. A security sensor is provided, and when an abnormality is detected, a signal is output from the security detection unit 1 and input to the control unit 3. Control unit 3
In response to this signal input, first, the identification code indicating the security detection section 1 is read from the storage section 2, the free channel is confirmed, and then the identification code is converted into a required high frequency signal for a cordless telephone via the transmission section 4. It is converted and transmitted from the antenna 5. Then, in response to a response from the security warning means B, a code (set depending on the cause of the abnormality and installation location) is read from the storage unit 2 via the control unit 3 and converted into a required high frequency signal for the cordless telephone via the transmission unit 4. It is converted and transmitted through the antenna 5.

The high frequency signal from the antenna 5 is transmitted to the antenna 11
Is received, is input to the receiving unit 12, and is demodulated. From the signal demodulated by the receiving unit 12, a code is extracted via the control unit 16 and input to the determination unit 14, compared with the data read from the memory unit 13 via the control unit 16, and the security signal corresponding to the code is determined. .. Then, the signal from the determination unit 14 is input to the alarm unit 15 via the control unit 16 to cause a fire, a gas leak, a window
An alarm is output when an abnormality such as a door occurs.

The output of the alarm unit 15 is notified by, for example, a specific alarm sound determined according to the cause of the abnormality, or by a synthesized voice set according to the cause of the abnormality and the place of occurrence. At this time, based on the signal from the determination unit 14, automatically dial the telephone number of the callee set in advance,
The occurrence of an abnormality may be reported by synthetic voice or the like.
Also, when the base unit has an answering machine function, by switching to answering machine recording, when the security sensor detects an abnormality, the synthetic voice is recorded to investigate the cause of the abnormality during absence. May be used as a clue.

[0011]

As described above, in the cordless security device according to the present invention, the signal based on the abnormality detection by the security sensor is converted into the high frequency signal for the cordless telephone and transmitted, and is received by the base unit of the cordless telephone. It demodulates and warns the cause and location of the abnormality, and there is no need to lay wiring for signal transmission from the security sensor. Therefore, it is particularly effective when installed in an existing building.
