Abstract

PROBLEM TO BE SOLVED: To make confirmable the state of terminal equipments in real time by restricting the equipment to which a state signal can be transmitted and preventing a data collision in communication. SOLUTION: The crime preventing receiver 1 transmits a transmission permitting signal only to terminal equipments 2-6 which permit the transmission of the state signal and inhibits the transmission of the state signal from the other terminal equipments 2-6. Thus, the state signal cannot be transmitted from the equipments which do not transmit the transmission permitting signal so that the data collision does not occur only when the equipment which permit transmission are restricted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security receiver applied to buildings and condominiums, and to a security monitoring system and an entrance / exit management system using the same.

[0002]

2. Description of the Related Art Conventionally, security receivers (center devices) have been installed in security rooms and management rooms of buildings and condominiums, while security sensors have been installed in passageways of buildings, in each room, and in windows thereof. Thus, a security monitoring system is configured. In such a security monitoring system, the security receiver monitors the operation state of the security sensor. When the security sensor operates, it is determined that there has been an intruder, and an alarm is issued from the receiver itself or a speaker in the building. Or output to a security company.

[0003] Such a security monitoring system operates in conjunction with the locking and unlocking of an electric lock provided at the entrance of each room.
An entry / exit management system may be configured. In this case, the security receiver sets the security alert by the security sensor in the room when the electric lock is locked, and cancels the security alert by the security sensor when the electric lock is unlocked. It has become. This allows the security receiver to manage the presence / absence state of each room and to make appropriate security settings. That is, when there is a user in the room, the security alert has been released, so there is no false alarm, and when the user in that room goes out,
Security alerts can be set automatically. In the security receiver, go out with forgetting to lock the door (locking the electric lock). If the security sensor does not detect the user for more than a predetermined time, the electric lock is remotely controlled and locked, and the security alarm is set. I can do it.

[0004]

However, the above-mentioned conventional security receiver, security monitoring system, and entry / exit management system have the following problems. Terminals connected to the security receiver, such as security sensors and electric lock control devices, use a contention-based security signal to detect state signals when the state changes between operation and normal, and between lock and unlock. Transmitting to receiver. Since this contention method is a method in which the transmitting side competes for the transmission right by sending a transmission request, as the number of terminals increases and the frequency of state changes increases, data collision on communication may occur. Occurred and the degree was high. Therefore, the transmission of the status signal is delayed, and the security receiver may not be able to confirm the status of the terminal device in real time.

On the other hand, a security receiver (center device) composed of a computer or the like displays a plan view of a building on a screen and displays a symbol of the terminal on the plan view, and the state of the terminal is displayed. Although it can be checked, the range that can be displayed at a time is limited, and it is not necessary to be able to immediately check the status of all terminals. The present invention has been made in view of such circumstances, and restricts a terminal that can transmit a status signal to prevent collision of data on communication and to check the status of the terminal in real time. It is an object of the present invention to provide a security receiver, a security monitoring system using the same, and an entry / exit management system.

[0006]

To achieve the above object, claims 1 to 3 of the present invention propose a security receiver. The security receiver according to claim 1, wherein a transmission permission signal is transmitted only to a terminal that permits transmission of a status signal, and transmission of a status signal from another terminal is prohibited. I do. As a result, no status signal is transmitted to the security receiver from a terminal that has not transmitted the transmission permission signal, and data collision does not occur if the terminals that permit transmission are restricted. .

According to a second aspect, in the first aspect, the security receiver includes display means for displaying a state of the terminal, and transmits a transmission permission signal only to the terminal displayed on the display. It is characterized by transmitting. Even if the terminal which is not displayed transmits the status signal, the status is not displayed on the security receiver, so that it is not necessary to transmit the status signal immediately. Therefore, the transmission permission signal is transmitted only to the displayed terminal. When the screen display is switched, the terminal that transmits the transmission permission signal is changed.

According to a third aspect, in the first or second aspect, only a terminal having a high frequency of transmission of a status signal is a target for transmitting a transmission permission signal, while a terminal having a low frequency of transmission of a status signal is The transmission of the status signal is always permitted without setting the transmission permission signal as the transmission target. This prevents data collision, limits the transmission target of the transmission permission signal, and reduces transmission control processing.

Claim 4 proposes a security monitoring system using the security receiver according to any one of claims 1 to 3, and at least any one of claims 1 to 3. Security receiver and connected to this security receiver,
It consists of a security sensor that operates when an intruder is detected. The security receiver outputs an alarm when the security sensor operates.

[0010] Claim 5 proposes an entry / exit management system using the security receiver according to any one of Claims 1 to 3, and at least one of Claims 1 to 3. The security receiver described above, a security sensor connected to the security receiver, which is activated when an intruder is detected, and an electric lock for controlling the locking and unlocking of an electric lock provided at the entrance of the section where the security sensor is installed. It is composed of a lock control device. When the electric lock is locked, the security receiver
While security alarm is set by the security sensor, when the electric lock is in the unlocked state, the security alert by the security sensor is released.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an example of a configuration of a security monitoring system or an entry / exit management system using a security receiver 1, and FIG. 2 is a diagram showing an installation state of a terminal in a room R in a building.

Here, a security receiver 1 (center apparatus) composed of a personal computer is installed in the manager's office, and a terminal installed in a passage in a building or each room is connected through a signal line L. ing. As a terminal device, an ID reading device 2 for reading an ID code from a predetermined ID card, and an entrance (door) of a section (room R) where the security sensor S is installed
Is connected to an electric lock control device 3 for monitoring the locked and unlocked state of the electric lock installed in the room and a security sensor S installed on a ceiling surface or a window in the room. When the state is input and there is a sensor input in the security alarm setting state, the sensor input device 4 that outputs an alarm signal is used for control such as interlocking with other systems,
An external output device 5 that outputs various status signals and an external input device 7 that inputs the status of various facilities and the like are connected.

In FIG. 2, if only the sensor input device 4 to which the security sensor S is connected is connected to the security receiver 1 (center device) via the signal line L, a security monitoring system is configured. The security receiver 1 monitors the state of the security sensor S via the sensor input device 4, and when the security sensor S operates, it determines that there has been an intruder, and the receiver 1
It outputs an alarm in itself or in a building or notifies a security company.

Further, as shown in FIG.
If an ID reader 2 and an electric lock controller 3 are connected via the signal line L in addition to the sensor input device 4, an entry / exit management system is configured. When entering this room R, I
An ID code (personal identification information) is read from a predetermined ID card by the D reading device 2, and when the read ID code matches the ID code of the user of the room R registered in advance, the electric lock control device 3 Release the lock. On the other hand, if the ID codes do not match, the electric lock keeps the locked state. Also, when the electric lock is locked, the ID card is read by the ID reading device 2.

Thus, in the security receiver 1, the presence / absence status of each room R can be managed, and the security sensor S is used in conjunction with the entry / exit of the room, specifically, in conjunction with the locking / unlocking of the electric lock. Security alerts can be set or canceled. When the electric lock is locked, the security receiver 1 sets a security alert by the security sensor S in the room R, while when the electric lock is unlocked, the security sensor S Release vigilance. Thereby, in the security receiver 1, when there is a user of the room R in the room R, the security alert is released, so that there is no false alarm. When the user of the room R goes out, the security alert is issued. Can be set automatically.

FIG. 3 is a block diagram showing the internal configuration of the security receiver 1. The security receiver 1 includes a CPU and the like, and includes a signal processing unit 10 that controls each unit, and a transmission control unit 1 that controls transmission between the terminals 2 to 6 through the signal line L.
1, a display unit 12 constituting a display means such as a CRT or a liquid crystal display, an operation unit 13 composed of a keyboard, a pointing device such as a mouse, and the like,
M and the like, and includes a storage unit 14 for storing data for managing a transmission target of a transmission permission signal described later, and a sound output unit 15 for outputting an alarm sound or the like from the speaker SP.

When the signal processing unit 10 receives the status signals from the terminals 2 to 6 via the transmission control unit 11, the signal processing unit 10 refers to the storage unit 14 based on the addresses and the like of the terminals 2 to 6, and Along with the states of the terminals 2 to 6, the symbols of the terminals 2 to 6 are displayed on the display unit 12. When an abnormality such as the operation of the security sensor S occurs, the sound output unit 15
As a result, a warning sound is output from the speaker SP.

In the present invention, the security receiver 1 transmits a transmission permission signal only to the terminals 2 to 6 that permit transmission of the status signal, and transmits the status signals from the other terminals 2 to 6. Prohibit transmission. As a result, the status signals are not transmitted from the terminals 2 to 6 that have not transmitted the transmission permission signal. In addition, in the security receiver 1, if the terminals 2 to 6 to which transmission is permitted are restricted, it is possible to prevent an increase in the amount of data transmitted at one time. Terminals 2 to 6 that allow
The status signal can be received in real time and the status can be confirmed. In addition, since the terminals 2 to 6 that are allowed to transmit the status signal are limited, it is not necessary to consider data collision, and the number of terminals 2 to 6 in the entire system can be increased.

FIG. 4 shows an example of the operation of the system of the present invention. In the figures, (a) to (h) show the security receiver 1
And the exchange of signals between two sensor input terminals 4 (sensor input terminal 1 and sensor input terminal 2). When the transmission of the status signal is permitted, the transmission permission signal is transmitted ((a), (f)), and when the transmission of the status signal is prohibited, the transmission prohibition signal is transmitted ((e)). After receiving the transmission permission signal, the sensor input terminal 4 can transmit the sensor signal until the transmission inhibition signal is received ((b), (d), (h)). No, and after receiving the transmission prohibition signal, the sensor signal cannot be transmitted ((c), (g)).

In (i) to (o), the security receiver 1
2 shows signal exchange between the sensor input terminal 4 and the external input device 6. Since the sensor input terminal 4 transmits an operation signal every time a human body is detected, the terminal input device 4 is a terminal device that frequently transmits a status signal.
A terminal device that transmits a status signal at a low frequency. Here, the external input device 6 is configured to transmit an alert set signal (security alert setting) and an alert reset signal (security alert release) by the security sensor S.

In the security receiver 1, only the terminals 2 to 6 having a high frequency of transmission of the status signal are targeted for transmitting the transmission permission signal, while the terminals 2 to 6 having a low frequency of transmission of the status signal.
Can always permit the transmission of the status signal without setting the transmission permission signal to be transmitted. That is, here, the transmission permission signal and the transmission prohibition signal are transmitted only to the sensor input terminal 4. The sensor input terminal 4 can transmit a sensor signal from the time when the transmission permission signal is received ((i)) to the time when the transmission prohibition signal is received ((m)) ((j), (l)). ), Sensor signals cannot be transmitted during other periods ((n)). On the other hand, the external input device 6 can transmit a status signal such as an alert set signal or an alert reset signal at any time without receiving a transmission permission signal or a transmission inhibition signal ((k), (o)). . By doing so, data collision can be prevented, and the transmission target of the transmission permission signal can be limited, so that the transmission control processing of the security receiver 1 can be reduced.

Next, FIG. 5 shows a display unit 1 of the security receiver 1.
2 shows an example of a screen display on the screen 2. On the screen, a part of the plan view of the building is displayed (in this figure, the “2F” portion), and the installation locations of the terminals 2 to 6 indicate the terminals 2 to 6.
Is displayed. The symbols also indicate the states of the terminals 2 to 6 at the same time. As shown in FIGS. 6A and 6B, opening and closing of a door (locking and unlocking of an electric lock) and a security sensor The normal state and operating state of S can be understood at a glance.

In the screen shown in FIG. 5, among the terminals 2 to 6, "sensor input terminal 1", "sensor input terminal 5",
The security sensor S managed by each of the "sensor input terminals 7" and the symbol of the electric lock (door) controlled by the "electric lock control device 2" are displayed. The security receiver 1 has terminals 2 to 6 displayed on the display unit 12.
It also operates to transmit a transmission permission signal only to. Terminals 2 to 6 that are not displayed transmit the status signal to the security receiver 1, but the status is not displayed.
There is no need to send a status signal immediately. Therefore, in the security receiver 1, only for the displayed terminal device,
Transmit the transmission permission signal. Of course, when the screen display is switched, the terminals 2 to 6 that transmit the transmission permission signal are changed. Also in this case, the terminals 2 to 6, which transmit the status signal at a low frequency, may transmit the status signal regardless of the screen display.

[0024]

As can be understood from the above description, in the security receiver according to the first to third aspects of the present invention, the transmission permission signal is transmitted only to the terminal that permits the transmission of the status signal. Is transmitted to prohibit the transmission of the status signal from another terminal, so that the terminals that can transmit the status signal can be restricted. Thus, the collision of data can be prevented, and the state of the restricted terminal can be confirmed in real time. Further, the number of terminals in the entire system can be increased without considering data collision.

In particular, since the security receiver transmits the transmission permission signal only to the displaying terminal, the state of the displaying terminal can be confirmed in real time. On the other hand, the terminal that is not displayed transmits the status signal, but the security receiver cannot confirm the status,
Even if the transmission of the status signal is prohibited, the effect is small. According to the third aspect of the present invention, since the security receiver sets only the terminal having a high frequency of transmission of the status signal as a target for transmitting the transmission permission signal, it prevents data collision and sets a target for transmitting the transmission permission signal. It can be limited and transmission control processing can be reduced.

A security monitoring system according to a fourth aspect of the present invention includes at least the security receiver according to any one of the first to third aspects and a security sensor. Status can be monitored. The entry / exit management system according to claim 5 includes at least the security receiver according to any one of claims 1 to 3, a security sensor, and an electric lock control device. , The interlock between the electric lock and the security sensor can be controlled, and the operating state of the security sensor and the locked / unlocked state of the electric lock can be monitored in real time.
