DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intruder surveillance system, and is particularly suitable for security of private houses, apartment houses, offices, etc., which have relatively few entrances.

[0002]

2. Description of the Related Art Conventional intruder surveillance systems employ windows, doors, ceilings, and the like of properties such as private houses, apartment houses, offices, factories, and warehouses.
When a sensor is installed on a wall or the like and the sensor detects an abnormality, if the monitoring mode of the controller is in the alert mode, the abnormality is reported to the security company's control center via a telephone line, etc. When the monitoring mode of the device is in the alert release mode, even if the intrusion sensor detects an abnormality, it is determined that the problem is caused by an internal person, and no alarm is issued. For this reason, in a private house, even if you enter from a non-living room such as a toilet or bathroom away from your room while you are at home, you will not notice it, or if you enter a living room over a balcony in a multi-family house, you will not emit any alarm If you live alone, leaving the sash windows on the balcony side open at night was dangerous. In addition, the basic requirement for changing the monitoring mode of a property such as a private house, an apartment house, an office, a factory, and a warehouse from the warning release mode to the warning mode is that a sensor installed in the property can detect an abnormality. In addition, all sensors installed in the property had to be monitored normally. That is, all doors, windows, etc. are closed, and in the case of a facing type sensor consisting of a light emitter, a light receiving device, etc. The condition was to make the whole unmanned. For this reason, for example, in the case of a private house, it is troublesome that it takes time and effort to switch to the alert mode only by leaving the house for a short time, such as shopping a little in the neighborhood. Also, for security equipment providers, installing a sensor for closing confirmation for each window, for example, a magnet sensor,
The number of uses increased, and it was not only time-consuming but also detracted from aesthetics, which was a cause of complaints. Also, since the sensors installed in the property were not able to be monitored at all times, there was anxiety about whether they would actually work in an emergency. In addition, in order to set only a part of the property to the alert release mode and set the others to the alert mode, it is necessary to perform an operation such as a partial alert release mode or a partial alert mode.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional monitoring system.
The purpose of this is that when going out for a short time, such as shopping a little in the neighborhood, the troublesome confirmation of closing is not performed, so that simply passing through the entrance will switch to the alert mode, and even in the alert release mode, The purpose is to issue an alarm when a person enters from a non-living room. Therefore, operations such as the partial alert release mode and the partial alert mode are not necessarily required. In addition, the number of magnet sensors installed can be reduced, and the installed sensors can be monitored by the customer at all times, thereby eliminating anxiety about the sensors.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a monitoring device for receiving output information of a sensor connected to a monitoring line and monitoring for an abnormality, a warning mode, and a warning release. In an intruder monitoring system comprising a controller for transferring output information of the sensor to a control center through a telephone line or the like based on each monitoring mode such as a mode, the sensor identifies a moving direction of a human body. The monitoring device includes a movement direction identification sensor, the monitoring device includes means for specifying output information of the sensor, means for processing and controlling the specified information, and means for outputting an alarm. Processing and determining the output information of the sensor based on the program, and controlling the alarm output based on the determined monitoring mode. That. Further, the sensors are classified into sensors related to the switching of the monitoring mode and sensors not related to the switching of the monitoring mode, and are monitored by independent monitoring lines. FIG. 1 is a block diagram of an embodiment showing a configuration of an intruder monitoring system of the present invention. Reference numeral 1 denotes a monitoring line.
a represents a sensor S involved in switching the monitoring mode.
1, S2 and S3 are connected, and the sensors include a movement direction identification sensor for identifying a movement direction of a human body. Sensors M1, M2, and M3 that are not involved in the switching of the monitoring mode are connected to the monitoring line 1b. 2 is a monitoring device, which specifies output information of each sensor sent through the monitoring line, processes the specified output information based on a predetermined program, and determines a monitoring mode, The alarm output is controlled based on the determined monitoring mode.

[0005]

The program for determining the monitoring mode can be created by the moving direction identification sensor for identifying the moving direction of the human body and the means for specifying the sensor information from the monitoring line. Can be processed to switch the monitoring mode to the alert mode or to switch to the alert release mode, so that the operation for switching to the alert mode in the past becomes unnecessary. Further, even in the alert release mode, it is possible to detect an intruder from a non-living room and intimidate with an alarm or the like, or to notify a person inside. Further, the sensors are grouped into sensors related to the switching of the monitoring mode and sensors not related to the switching of the monitoring mode, and are monitored. The means for specifying the sensor information is simplified, and the detection accuracy for specifying the sensor information is improved. In addition, if you want to close the door completely, such as by leaving the property unattended for a long period of time, and confirm that the door is closed, then set the controller to the alert mode, you can manually set the controller to the alert mode. It is easy to distinguish between the alert mode (attended) when going out for a short time and the alert mode (unattended) when going out for a long time after leaving unattended. In addition, when a sensor related to the switching of the monitoring mode is activated, it becomes easy for the customer to confirm with a warning sound or a lamp display.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The operation of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram of an embodiment showing the configuration of an intruder monitoring system according to the present invention. FIG. 7 shows an example in which this configuration is applied to an apartment house. Reference numeral 1 denotes a monitoring line, and a sensor related to switching of the monitoring mode is connected to the monitoring line 1a. S1 and S3 are moving direction identification sensors for identifying the moving direction of the human body, and S2 is for detecting the movement of the human body. It is a space sensor. In a normal monitoring state in which the sensor has not detected an abnormality, the monitoring line 1a forms a closed circuit with the terminating resistor RT. A sensor that is not involved in switching the monitoring mode is connected to the monitoring line 1b.
1, M2 and M3 are magnet sensors. In a normal monitoring state in which the sensor has not detected an abnormality, the monitoring line 1b forms a closed circuit with the terminating resistor RT. A monitoring device 2 includes a sensor information specifying unit 4, a processing control unit 5, and an alarm output unit 6. The sensor information specifying unit 4 specifies sensor information from a monitoring line. Controls the alarm output means 6 and the controller 3 based on the determined monitoring mode by processing the specified sensor information based on the program and determining the monitoring mode.

Various means for specifying sensor information have been proposed. As an example, a case where various resistance values are transmitted as a medium for transmitting sensor information will be described.
Since the sign of the sensor connected to the monitoring line in FIG. 1 corresponds to the sign of the sensor installed in the apartment house in FIG. 7,
This will be described with reference to the installation drawing of FIG. The moving direction identification sensor S1 is installed at the entrance, and the output of the sensor S1 is a resistance R1 when the human body moves from the inside to the outside,
When moving from outside to inside, the resistor R2 is output. The moving direction identification sensor S3 is installed in a Japanese-style room so that intrusion from a sash window can be detected, and the output of the sensor S3 is
When the human body moves from inside to outside, resistance R3
When the human body moves from the outside to the inside, the resistor R4 is output. The space sensor S2 is installed in the living room at the center, and outputs a resistance R5 when detecting the movement of the human body. The magnet sensor M1 is installed on the door of the entrance, and outputs the resistance R1 when the door is opened. Also, the magnet sensors M2, M
3 are installed on the left and right sides of the sash window, and output the resistors R2 and R3 when the sash window is opened. The output resistances R1, R2, and R3 of the magnet sensors M1, M2, and M3 are the same as the output resistances of the movement direction identification sensors S1 and S3. It is. In addition, if a sensor that keeps the output state like a magnet sensor outputs many at the same time on the same monitoring line, it becomes impossible to specify the resistance value, and which magnet sensor is operating in the above-mentioned state. Since it does not make sense to specify, it is more advantageous to monitor independently of the sensors involved in switching the monitoring mode. Also, by making them independent, the types of resistance values specified on the same monitoring line can be reduced, and the width between the resistance values can be widened, so that the detection accuracy for specifying the resistance values can be improved. it can. As described above, the sensor information can also be specified by specifying the resistance value of the monitoring line. FIG. 2 shows an example of the sensor information specifying means 4 of the monitoring device as disclosed in Japanese Patent Application No. 7-306329 by the present applicant. The case where the “method for specifying the operation detector in the monitoring system” will be described, but the sensor information specifying unit 4 is not limited to the above.

As shown in FIG. 2, the amplifying circuit of the sensor information specifying means 4 includes an operational amplifier A, and a detection resistance value inserted in series with a monitoring line is provided between the inverting input terminal of the operational amplifier A and the ground. And the feedback resistor Rf connected between the output terminal and the inverting input terminal of the operational amplifier A is sequentially selected from among the resistors of the feedback resistor group 41 so that the variable gain amplification by the operational amplifier A is performed. Form a circuit. The feedback resistor group 41 includes a terminating resistor RT and resistors having the same resistance values as the output resistors R1 to R5 of the sensors S1, S2, S3 and the sensors M1, M2, M3, and the feedback resistor Rf is connected to the switching element SW2 (SW
21 to SW25). If the line resistance of the monitoring line cannot be ignored, the line resistance is corrected. However, since the correction of the line resistance is not the main purpose of the present description, the line resistance can be ignored in the present embodiment. The sensor information specifying means 4 includes an A / D converter 42 for converting the output voltage of the variable gain type amplifier circuit into a digital signal in addition to the variable gain type amplification by the operational amplifier A, and a judging means 43 for judging the result. A switching element SW1 (SW11, SW12) for capturing a monitoring line; a driving circuit 45 and a driving circuit 46 for driving the switching elements SW1 and SW2; and an address / decoder 44 for sequentially selecting the driving circuits 45 and 46; The alarm output means 6 is provided. In the above configuration, the switching element SW
2 is switched in accordance with the address / decoder 44, so that all the resistors of the feedback resistor group 41 are selected as the feedback resistor Rf of the variable gain amplifier circuit by the operational amplifier A, and an output voltage determined by the respective amplification factors is obtained. . When the resistance value of the monitoring line matches the resistance value of the feedback resistor Rf of the variable gain type amplifier circuit, the output voltage of the variable gain type amplifier circuit becomes equal to the monitor voltage VK,
The resistance value of the monitoring line can be specified by the address at this time. The specified information is stored in the CP of the process control unit 5.
Input to the port of U51, the output of CPU51 is output to the alarm output means 6 and the controller 3. The CPU 51 controls the entire monitoring device and the controller 3; 54 is an address bus;
2 stores the processing control program shown in FIGS. 4 to 6 and FIG. 8, and the monitoring mode is determined based on the processing control program.

FIG. 3 shows an example of sensor information specified as an address. From address 0000 to address 0111, the switching element SW1 is SW
11 is selected, and while the SW11 is selected, the switching elements SW2 are sequentially selected from SW21 to SW25. From address 1000 to address 1111
Up to this point, SW12 is selected as the switching element SW1,
While the SW12 is selected, the switching element S
As for W2, SW21 to SW25 are sequentially selected. In FIG. 3, for example, when the output of the variable gain amplifying circuit by the operational amplifier A becomes equal to the monitor voltage VK at the address 0000, the resistance value of the monitor line 1a is specified as RT, which is the value of the monitor line 1a. Sensors S1, S2 and S
3 shows that all are normal and no abnormality is detected. When the output of the variable gain amplifier circuit becomes equal to the monitoring voltage VK at the address 0001, the resistance value of the monitoring line 1a is specified as R1, which indicates that the moving direction identification sensor S1 has output the resistance R1. This indicates that the human body has moved from inside to outside at the entrance.
In this embodiment, no switching element is provided for the addresses 0110 and 0111 because there is no resistance value to be specified. Therefore, the addresses 0110 and 0111 specify the terminating resistor RT in the same manner as the address 0000. Disconnection, short-circuit, for a specified address or all addresses, if the output of the variable gain amplifier circuit is lower than the voltage that defines the disconnection of the monitoring line, disconnection abnormality, higher than the voltage that defines the short circuit If it does, it will be detected as a short-circuit abnormality. Next, when the output of the variable gain amplifier circuit by the operational amplifier A becomes equal to the monitor voltage VK at the address 1000, the resistance value of the monitor line 1b is specified as RT, and the sensors M1 and M1 of the monitor line 1b are specified.
M2 and M3 are all normal and indicate that no abnormality is detected. When the output of the variable gain type amplifier circuit becomes equal to the monitor voltage VK at the address 1001,
The resistance value of the monitoring line 1b is specified as R1, which indicates that the magnet sensor M1 has operated, that is, the door of the entrance has been opened. Address 1100, 110
1 is specified when the resistance value of the monitoring line 1b is R4 or R5, but can be specified since the sensor having the output resistance value of R4 or R5 is not used for the 1b line in this embodiment. There is no. As described above, the address has been described as an example of 4 bits. However, since the number of monitoring lines can be increased by increasing the number of bits, it is possible to specify even a sensor having the same output resistance value, and be alert. Even if the number of rooms increases, it will be possible to respond sufficiently.

FIG. 7 shows a case where the monitoring system is constructed with the basic configuration. FIG. 9 shows the simplest installation example of the intruder monitoring system of the present invention, and FIG. 8 shows an operation flowchart. The sensor used as shown in FIG. 9 is composed of two movement direction identification sensors S1 and S3.
FIG. 8 shows an example of the installation example of FIG.
In the operation flowchart executed by 51, an operation for switching from the alert release mode to the alert mode is described. First, the initial mode is the alert release mode (S40).
1) When the human body crosses the moving direction identification sensor S1 at the entrance, the sensor S1 detects that the human body has moved from inside to outside (S402), and the timer starts (S404). At the same time, a warning is displayed by a buzzer, lamp, etc. (S405),
At the same time as the timer expires (S406), the mode is switched to the alert mode (manned) (S408). If the user returns to the living room across the sensor S1 with a lost item or the like before the timer expires (S407), the process returns to the alert release mode (S401). Conversely, if the sensor S1 detects that the human body has moved from outside to inside in the alert release mode (S402), the sensor S1 is notified with an abnormal alarm (such as a chime) (S403). Further, the operation flow chart when the customer goes out of the balcony and returns to the room in the alert release mode with the above sensor configuration or when an intruder enters from the balcony is the same as that in FIG. If it is intruded, it issues an abnormal alarm (intermittent sound, etc.). When the controller is set in the alert mode using an operating device such as a magnetic card, there is a difference that the closing confirmation is not performed by the magnet sensors M1, M2 and M3, but the function of detecting and reporting an intruder is equivalent. It is. As described above, the case where the present invention is applied to an apartment house has been described as an example, but it is possible to increase the number of address bits even in a case where there are multiple entrances and exits in a private house, an office, etc. is there.

[0014]

Since the present invention is configured as described above, it has the following effects.

Conventionally, it has not been possible to discriminate between an intruder and a customer, but it is now possible to discriminate by specifying a moving direction of a human body and an activated sensor. Thus, when going out, the user can go out without any troublesome operation, regardless of whether the property is manned or unattended, and can automatically switch to the alert mode.

If the sensor detects the presence of a person inside after the property is switched to the alert mode while the property is manned, the alert is automatically returned to the alert release mode, so that an abnormality report by an inside person does not occur.

[0017] Even in the alert release mode, it is possible to notify a visitor from the entrance by an alarm sound such as a chime to notify an intruder from a non-room. Thus, it is possible to intimidate an intruder with an intermittent sound or a lamp display, or to notify the presence of an intruder.

When it is desired to enter the unattended security mode in order to leave the property unattended for a long period of time, it is possible to perform a conventional security mode operation requiring confirmation of closing and manual operation.
In this case, if a man is detected inside, it is determined that the person is an intruder and an abnormality is notified. Therefore, the security mode (attended) when going out for a short time and the security mode (unattended) when going out for a long time can be used properly, which is very convenient.

When a sensor related to the monitoring mode is activated, a warning sound or a lamp is displayed, so that the customer can always monitor, giving a sense of security and reliability. In addition, since the trouble is immediately pointed out for the device provider, the device can be operated in the best condition, and the maintenance becomes extremely easy.

In addition, it is possible to construct an intruder monitoring system that does not use a magnet sensor at all, and it is possible to provide a low-cost security system to a customer and also to solve a problem that is difficult in aesthetics. .
