In this way, when the entire building, etc. is unattended, the general shared security area and the specific shared security area are not in an unguarded state, ensuring the security of the building, and the specific security area has a specific shared security area. Since the area remains in the release mode, unnecessary information such as abnormality information is not detected when there is a person in the specific security area.

Hereinafter, the present invention will be described in more detail based on embodiments shown in the accompanying drawings. FIG. 1 schematically shows a building 10 which is the entire guard area. Independent blocks B1, ... B5, which are multiple independent security areas with different working hours and different business departments, etc. General shared blocks which are general shared security areas commonly used by people belonging to building 10 B0, belonging to a specific block TB1 and a specific block that is a specific security area used by a specific person, such as a manager room where a manager is stationed, a nap room used at night, a data center where a specific person works, etc. It consists of a specific shared block TB0, which is a specific shared security area that is shared by a specific person using the block.

Each independent block B1,... B5 and specific block TB1 are provided with local control devices LC1,. Each local control device LC is installed outside the corresponding block in this embodiment, but may be installed inside the corresponding block.
Each block is provided with sensors S0,... S8 for detecting intruders.
As shown in FIG. 2, each of these local control devices LC is centrally controlled by one control device CC. The control device CC is connected to the host computer HC in the control center of the security system by a transmission line.

  The local controller LC will be described with reference to FIG. Each local control device LC is composed of a well-known CPU, ROM, RAM, etc., and is connected to other devices via an interface 13 or a peripheral control circuit (including an I / F or I / O function) 14. ing. A display device 16 which is a notification device composed of various LEDs, a liquid crystal display and a CRT, an input device 18 composed of an operation touch panel, etc., and a card reader 20 for reading a magnetic card are connected to a peripheral control circuit 14, and an electric lock device 22 and a detection device 24 including a sensor for detecting an abnormality are connected to the interface 13.

The sensors S1 to S5 are connected to the local control devices LC1 to LC5, the sensor S6 is connected to the local control device LC6, and the sensors S0, S7 and S8 are connected to a control device CC which will be described later.

The display device 16 is a device for notifying a person in each block, and an audio device can be used instead of a visual means. The card reader 20 is an example of a mode setting device. In this embodiment, the security state of the block (hereinafter referred to as “set”) and the security release (hereinafter referred to as “released” or “not set”) will be described, but there are other patrol security modes. May be.

The control device CC will be described with reference to FIG. The control device CC is composed of CPU, ROM, RAM, etc., and the display device 28 and the input device 30 are connected via the peripheral control circuit 26, and the local control device LC and the communication device 34 are specified via the interface 25. The sensors S0, S7 and S8, which detect abnormalities in the common block and the common block, are connected to the detection device 24, and the communication device 34 is connected to the host computer HC of the control center. The time measuring means is timed by the CPU.

Below, this security mode setting method and a security system are demonstrated according to the flowchart shown in FIG.
The flowchart shown in FIG. 5 is a program in the control device CC. In step 40, it is determined whether or not the number of independent blocks that are not in the set state, that is, in the released state, is a predetermined number PN, for example, in this embodiment, the number of independent blocks is 5, so that it is 2 blocks or less. For example, in FIG. 1, it is assumed that only the independent blocks B1 and B2 have people, so that the security mode is in a released state, and the other independent blocks B3, B4 and B5 are in a set state.

In this case, in step 42, a dunning message is transmitted to each local control device LC1 and LC2 of each independent block B1 and B2. In each independent block B1 and B2, the above reminder message is displayed on the display device 16, and the people in each independent block B1 and B2 are those who leave the building 10 at the end except those who are in the specific block TB1. Know that there is a possibility.

In step 44, it is checked whether there is an independent block that has not been set in independent blocks B1 and B2. If both independent blocks remain unset, the independent state that was already set in step 46 It is checked whether there is an independent block newly released from the blocks B3, B4, and B5. That is, it is checked whether the number of unset independent blocks is larger than PN (= 2). As a result, if the number of unset independent blocks is larger than 2, all the reminder messages for independent blocks B1 and B2 are cleared in step 48. Then, the process returns to step 40 again.

If any of the unset independent blocks B1 and B2 is set in step 44, it is determined in step 50 whether all the independent blocks B1 to B5 are set. Here, if the independent block B1 is set, the process proceeds to step 50.
The control device CC connects the individual control blocks B1 to B5 and the local control devices LC1 to LC6 of the specific block TB1 to the control device CC, and the mode states of the independent blocks B1 to B5 and the specific block TB1 are, for example, Since each local control device LC is polled at intervals of several tens of milliseconds, the above-described control becomes possible.

For the mode setting of each of the independent blocks B1 to B5 and the specific block TB1, the local control device LC sets the security mode compared to the previous state by inserting the magnetic card of the card reader 20, for example. In other words, when the magnetic card is operated by the local control device LC while the security mode is set, the security release mode is set. When the previous state is the security release mode and the magnetic card is operated by the local controller LC, the security mode is set.

Next, when the last unset independent block B2 is set, all the independent blocks B1 to B5 are set, so that a timer T for measuring a predetermined time is started in step 52.

The last person of the independent block B2, which is the last set in the independent block, walks toward the exit door D1 through the general shared block B0 and exits from the exit door D1. When the timer T expires in step 54, the control device CC sets a general shared block B0 in step 56. Therefore, if the sensors S0 and S8 installed in the general shared block B0 thereafter detect an abnormality, the control device CC transmits it to the host computer HC via the notification device 34.

In step 58, the control device CC determines whether or not the specific block TB1 is set. If the specific block TB1 is set, the specific shared block TB0 is set in step 60, and if the specific block TB1 is in the released state, the specific shared block TB0 also maintains the released state.
The time T is set, for example, until the last person of the independent block B2 sets the independent block B2 in the set state and then leaves the building 10 via the exit door D1.
When the specific block TB1 is set, all the independent blocks B1 to B5 and the specific block TB1 are in the guard state, and when the specific block TB1 is in the released state, each independent block except the specific block TB1 and the specific shared block TB0 Blocks B1 to B5 and general shared block B0 are in a guarded state.

The first visitor enters the office the next morning through exit door D1. At this time, opening of the exit door D1 is detected by the sensor S0 and transmitted to the control device CC. In response to this detection signal, a delay timer (not shown) starts operating, and when the magnetic card is inserted into the card reader 20 connected to the local control device LC of the independent block and the security mode is canceled, it belongs to itself. The independent block is released, and the general shared block B0 specific shared block TB0 is also released.
Since the general shared block B0 has already been released, the delay timer does not operate even if a subsequent visitor opens and closes the exit door D1. The time of the delay timer and the time of the timer T may be the same or different.

In the present embodiment, the specific block TB1 has been described at one place, but a plurality of specific blocks TB1 may be provided. In this case, it may be determined in step 58 whether all the specific blocks TB1 are set.
Although the mode setting device has been described with a magnetic card, it goes without saying that a numeric keypad or other function buttons may be used.
