Is converted. Note that the first conversion unit 27 converts the security signal S based on a protocol form uniquely determined by the manufacturer of the control device 20 into RS-232 standard RS-232 standard.
Converted to C form.

The second converter 28 is connected to the first converter 27, and the second converter 28 converts the first signal S1 converted by the first converter 27 into the communication network. At step 16, the data is converted into a protocol form that can be transmitted. That is, the second converter 28 converts the RS
The first signal S1 of the H.-232C format is transmitted by a TCP (Transmission control pr
otocol) / Second signal S in IP (Internet protocol) format
2 is converted. Further, the DHCP unit 29 is connected to the second conversion unit 28, and the DHCP unit 29 transmits the second signal S2 converted into a TCP / IP format through the communication network 16 by a DHCP connection. It has become. Further, the encrypting unit 30 is connected to the DHCP unit 29, and the encrypting unit 30 transmits the second signal S2.
Is generated as a security signal SX.

Next, as an example of the security management of the house 11 in the security system 10, the movement of a resident (human) during bathing is detected by the abnormality detection sensor 19 (bathroom sensor), and based on the detection result, A mode of notifying the security agency 14 will be described.

First, the abnormality detection sensor 19 operates to determine the movement of a person who is taking a bath based on the algorithm described above. Then, the abnormality detection sensor 19
When the detection result corresponds to the detection result set as the abnormal state (detecting the state of stopping the movement of the human in the bathroom), a security signal S is sent to the control device 20 (control unit 26).
Is output. Next, the control unit 26 of the control device 20 converts the security signal S emitted from the abnormality detection sensor 19 into a first signal S1 of the RS-232C format by the first conversion unit 27, and then converts the signal S1. Output to the second conversion unit 28.

Subsequently, the second converter 28 converts the input first signal S1 into a second signal S2 of a TCP / IP format, and then converts the signal S2 into a DHCP unit 29.
Output to Then, in the DHCP unit 29,
An IP address is obtained from a DHCP server (not shown) connected to the communication network 16, and a DHCP connection is made to the communication network 16 based on the IP address. Further, the DHCP unit 29 outputs the second signal S2 to the encryption unit 30, and the encryption unit 30 encrypts the input second signal S2 to generate the security signal SX.
Thereafter, the control unit 26 outputs the security signal SX to the communication network 16 via the cable modem 21, and the security signal SX is transmitted to the personal computer 22 of the security agency 14 via the communication network 16. In addition, the control unit 26 transmits a unique identification signal previously assigned to each control device 20 to the personal computer 22 of the security agency 14 via the communication network 16 together with the security signal SX.

On the other hand, in the security agency 14, the house 1
The security signal SX transmitted from the PC 1 is received via the communication network 16, and the security signal SX is input to the personal computer 22 via the DSU 25, the router 24 and the hub 23. In the personal computer 22, the security signal SX is decoded into a second signal S2 (a signal in the form of TCP / IP) converted by the second conversion unit 28 by a decoding unit (not shown). Also, the personal computer 22 converts the decoded second signal S2 into the first signal S1 (signal in the form of RS-232C), and the abnormality detection sensor 19 emits the first signal S1. It is converted into a security signal S.

As a result, the security signal S generated by the abnormality detection sensor 19 of the house 11 is transmitted to the personal computer 2 of the security agency 14.
2 is written. That is, the personal computer 22 performs a process reverse to the process in which the control device 20 of the house 11 converts the security signal S into the security signal SX. And
The personal computer 22 sends the home 11 based on the identification signal.
Recognizing that there has been a report from the (abnormality detection sensor 41), the security agency 14 carries out measures such as contacting the house 11 or dispatching a guard.

When the emergency button 18 is pressed, similarly to the security signal S emitted by the abnormality detection sensor 19,
The control device 20 converts the security signal SX into a security signal SX, and the security signal SX is transmitted to the personal computer 22 of the security agency 14 via the communication network 16. Then, a guard of the security agency 14 checks the situation from a resident of the house 11 through a telephone line connected to the control device 20.

When the resident of the house 11 moves in and out, the controller 20 (control unit 26) also outputs an entry / exit signal issued by the controller 20 in the same manner as the security signal S.
The signal is converted into a CP / IP signal. Then, the converted entry / exit signal is transmitted to the personal computer 22 of the security agency 14 via the communication network 16.

And the user can use the security system 10 with a sense of security.

(6) The control device 20 converts only the security signal S generated when the detection result of the abnormality detection sensor 19 corresponds to the detection result set as the abnormal state in advance into a TCP / IP signal. The data is transmitted to the security agency 14. Therefore, the load on the control unit 26 that converts the security signal S can be reduced, and the burden on the personal computer 22 of the security engine 14 can be reduced without transmitting unnecessary signals to the security engine 14. it can.

(7) The control device 20 is provided with a DHCP unit 29 for making a DHCP connection to the communication network 16. Therefore, it is possible to cope with the DHCP connection on the Internet using the communication network 16 and to cope with the transmission and reception of information from the unspecified number of users through the communication network 16 unlike the fixed IP connection. Also, the security device 17 (control device 2) owned by the user (security target) of the security system
No need to assign an IP address (fixed IP address) to 0) in advance. Therefore, in the security agency 14, if the control device 20 is connected to the communication network 16, all of the control device 20 becomes a security target and the security range can be greatly expanded.
