In addition, Figure 9 is a table showing the type of the waveform and signal and the cover signal transmitted during the operation of the building monitoring and control system according to the present invention.

6, 8, and 9 will be described in more detail the operation of the building monitoring and control system using the wireless communication shown in FIG.

(1) Wireless card access detection and authentication process (C1)

The main device 100 installed inside the building periodically transmits a first long wave LF1 including a synchronization signal in order to detect the approach of the wireless card 200.

When the user having the wireless card 200 approaches the main device 100, for example, within 1 m, the wireless card 200 receives the first long wave LF1. The wireless card 200 receiving the first long wave LF1 turns on the internal power supply circuit.

The wireless card 200 then transmits the 80-bit first microwave VHF1 including the ID code. In this process, the wireless card 200 is synchronized by the first long-wave LF1 to generate a periodic code in a random (RANDOM) manner. Subsequently, the wireless card 200 loads the unique data stored in any one of the plurality of channels in a periodic code and transmits the first data to the first microwave VHF1. As a channel for transmitting the unique data to the wireless card 200, for example, 10 channels may be provided to select any one of them.

According to a preferred embodiment of the present invention, the wireless card 200 generates a new code every time by means of a period code, a mode code, and a checksum bit in addition to an ID code of 32 bits, which is referred to herein as an ALLFREE CODE.

Further, according to a preferred embodiment of the present invention, by changing the period by a random cycle code, it is prevented from being repeatedly transmitted in the same period.

The main device 100 receives the first microwave VHF1 transmitted from the wireless card 200 to detect the ID code. Then, the detected ID code and the ID code previously stored in the memory are compared with each other. In this specification, this is referred to as primary ID verification. As a result of the primary ID checking, if the mutual ID matches, the main device 100 converts the period code among the signals included in the first microwave VHF1 into a long wave ID and transmits the second long wave LF2 including the same. As a result of the primary ID check, if they do not coincide with each other, the initial state, that is, the door lock state is returned.

The wireless card 200 compares a long wave ID carried in the second long wave LF2 with a periodic code generated by a random method when transmitting the first microwave. In this specification, this is called secondary ID verification. As a result of the secondary ID check, if the mutual ID matches, the second microwave VHF2 including the ID code and the unlock request signal is transmitted. Subsequently, the device enters the standby (STAND-BY) state to maintain only the long-wave receiving circuit.

At this time, the door lock detection switch 310 is provided to define the door lock position by driving the motor of the door lock means. In more detail, when the door lock detecting switch 310 detects UNLOCK, the motor is stopped to prevent the motor from being overloaded.

When the door locking means is released, the door controller 300 transmits the fourth microwave VHF4 including the lock release confirmation signal. The main device 100 receives the fourth microwave VHF4 and checks the unlock state of the door. According to an embodiment of the present invention, the main device 100 voices the unlock state of the door. After unlocking, the door open / close detection switch 140 installed in the door detects whether the door is opened or closed by the user and reports to the main device 100.

In the door unlock state, when the door open / close detection switch 140 reports that the door is not opened within a predetermined time, the door control device 300 automatically locks the door and the main device 100 receives a door lock message. Output through the speaker. According to an embodiment of the present invention, the predetermined time for determining whether the door is open is set to 10 seconds.

In the door unlocking state, when the door open / close detection switch 140 reports that the door is opened within a predetermined time, the door open / close detection switch 140 reports that the door is closed while maintaining the open state. ) Checks whether the wireless card 200 is in a proximal position through bidirectional communication with the wireless card 200. If it is determined that the wireless card 200 does not exist, the door control device 300 drives the motor installed in the locking means to lock the door. Subsequently, when the door lock detection switch 310 detects a door lock state, the door control device 300 stops the motor so that the motor is not overloaded.

When the lock is activated, the door lock transmits the fourth microwave VHF4 including the lock signal and receives the signal from the main device to inform the speaker that the door is closed.

On the other hand, when the wireless card 200 moves away from the main device 100 or the building by a predetermined distance, for example, 3 m or more, communication between the main device 100 and the wireless card 200 is cut off. In this case, the main device 100 enters an initial state and sends a door lock command to the door control unit 300. Therefore, when the user wants to lock the door by going out, the door is automatically locked without performing a separate locking operation.

According to a preferred embodiment of the present invention, since most of the communication is wireless, it is not necessary to install a key holder or a sensing unit outside the door. Accordingly, it is not possible to determine where the door control unit 300 or the door locking means is installed in the building only by the exterior of the building. Therefore, there is little possibility that the door locking means and the door control part 300 will be physically damaged by an external shock or by the intention of a third party.

According to the present invention, most data communication between the wireless card 200 and the main device 100 is performed by two-way wireless data communication. At this time, since the wireless card 200 undergoes an authentication process for confirming whether the wireless card 200 is already registered valid, even if any wireless card 200 except the valid wireless card 200 comes close, the main device 100 or Other devices cannot be released from their initial state, ie locked state. Therefore, the operation such as opening or unlocking the door is not performed without the wireless card 200 registered in advance with respect to the main device 100.

(3) indoor home appliance control process

FIG. 7 illustrates indoor home appliances using a building monitoring and control system including a main device 100 for a building, a phone control unit 150, a home appliance control unit 410, 420, 430, and a wireless intrusion detection unit 110. It is a flowchart for explaining the process of controlling.

When the user calls the telephone control unit 150 through an external telephone line and inputs a control signal, the telephone control unit 150 performs a control signal verification process for confirming whether the input signal is a control signal of a selected method. (H1)

As a result of the determination by the telephone control unit 150, if it is determined that the input signal is a general voice signal instead of the control signal of the selected method, the changeover switch 153 is switched to the normal telephone. Accordingly, when the general telephone is to be talked to via the external telephone line, communication between the external telephone line and the ordinary telephone proceeds.

If it is determined that the input signal is a control signal of the selected method, the phone controller 150 enters the home automation mode and performs the control unit control process (H2).

In the home automation mode, the DTMF transceiver 152 converts the control signal and the control unit designation signal from the input signals into digital signals. The second microprocessor 151 processes the digital signal from the DTMF transceiver 152 and transmits the processed digital signal to the first microprocessor 101 through the serial port. The main device 100 converts a control unit designation signal into a device specific code among the received control signals. Subsequently, the fifth ultra-high frequency VHF5 including the power supply control signal and the device specific code is transmitted.

Each home appliance control unit 410, 420, 430 installed in the receptacle receives the fifth high frequency (VHF5) signal transmitted by the main device, checks the device unique code, and then turns on / off the power supply according to the power control signal. Can be turned off.

In addition, the device can perform an intrusion detection alarm and an external automatic telephone function in conjunction with an internal home appliance control process.

In case of intrusion without a normal authentication process, the intrusion detection sensor 110 such as a motion detection sensor installed indoors detects this and transmits the sixth microwave VHF6 including the detection signal to the main device 100. do. The determination of whether an intrusion is performed without a normal authentication process or the like may be assumed, for example, when the intrusion is detected while the door is locked.

The main device 100 receives the sixth microwave VHF6 transmitted by the intrusion detecting device 110 to operate the voice alarm device 120 so that an alarm sounds.

In addition, the main device 100 outputs an emergency phone number and an alarm message previously stored in the memory 102 to the phone controller 150. In order to call an emergency telephone number, it is preferable to record in advance the same telephone number as the home automation telephone number used when the user controls the indoor household appliances from the outside.

The telephone control unit 150 receives an emergency telephone number and an alarm message from the main device 100 and switches the changeover switch 153 to the home automation mode to enable control via an external telephone. Then, a telephone number capable of controlling home appliances from outside, that is, an emergency telephone number, is called and an alert message is sent.

In the above description, the present invention has been mainly described with respect to the use of controlling the door of the building and controlling indoor home appliances.
