DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of a security terminal device according to the present invention. The security terminal device 1 is a sensor S1 for detecting a large number of intruders arranged in a building B which is a facility to be protected. Through S8. In the present embodiment, the building B, which is the facility to be guarded, has three tenants, and each tenant has a first guard area B1,
It is divided into a second security area B2 and a third security area B3, the sensors S1 and S2 are arranged in the first security area B1, and the sensors S3 and S4 are arranged in the second security area B2. S5 to S8 are arranged in the third security area B3.

In the security terminal device 1, these sensors S1 to S8 are used to detect the presence or absence of intrusion in each security area.
Are input to the grouping device 2. The grouping device 2 is connected to a terminal block 3 provided with a large number of input terminals X1, X2, X3, ..., Xn for connecting output lines from sensors, and these input terminals X1 to Xn. An output terminal Y which receives the output from each sensor and provides the output for each sensor group grouped according to the information for grouping given in advance.
, Ym, and a matrix circuit 4 having Ym.

That is, by the matrix circuit 4,
A large number of sensors S1 to S8 are grouped in security area units, and when any sensor in the first security area outputs an abnormal signal, the first abnormal signal A1 representing this group is output to the output terminal Y1. In the same manner, the second abnormal signal A2 representing this group is output to the output terminal Y2 by outputting an abnormal signal from any one of the sensors in the second security area, and the sensor in the third security area is output. By outputting any one of the abnormal signals, the third abnormal signal A3 representing this group is output to the output terminal Y3.

Each abnormal signal output from the matrix circuit 4, that is, the grouping device 2, is input to the transmitter 5. The transmitter 5 has a configuration of m input channels in the illustrated example, responds to the first to mth abnormal signals that can be input, and distinguishes between these signals to notify a monitoring center (not shown) via a telephone line or the like. This is a known structure for transmitting a signal. In FIG. 1, the security area B, which is each security area
In order to independently start and release the guards 1, B2, and B3, the operation boxes provided corresponding to the respective guard areas are omitted from the drawing.

FIG. 2 shows an example of a detailed circuit of the grouping device 2. The input terminals X1 to Xn are provided with corresponding buffer amplifiers C1, C2, ..., C.
The output terminals Y1 to Ym are connected to the horizontal matrix lines L1 to Ln extending in one direction through n, and
The vertical matrix lines M1 to Mm are arranged so as to extend in the other direction substantially orthogonal to the horizontal matrix lines.

At each point where the horizontal matrix line and the vertical matrix line intersect, a connecting terminal for a jumper wire for connecting the two intersecting lines is provided as shown in the drawing. Any of the matrix lines and any of the vertical matrix lines can be arbitrarily connected by using a jumper wire.

In the case of the embodiment shown in FIG. 1, the sensor S
In order to obtain the representative signal from the output terminal Y1 by grouping 1 and S2 into one group, the jumper wire J is connected to the connection terminals T1 and T2.
1, J2 are connected. Similarly, the connection terminal T3
Jumper wires are connected to T8 to T8 respectively.
Grouping of sensors is performed.

According to this structure, the sensors connected to the input side of the matrix circuit 4 can be arbitrarily divided into groups by only selectively attaching the jumper wires to the respective connection terminals of the matrix circuit 4, which has the following advantages.

(1) Regardless of how the security areas B1, B2, B3 are divided, it is possible to cope with the installation or change of the security area immediately by installing the jumper wires. (2) No problem occurs even if only one security area is very wide or narrow. (3) When a sensor is added in the guarded area, the output of the sensor can be connected to an appropriate input terminal and the jumper wire can be attached thereafter, so that the addition of the sensor can be handled very flexibly.

Although one embodiment of the security terminal device according to the present invention has been described above, the security terminal device according to the present invention can be similarly applied to the case where one tenant is divided into a plurality of security areas. It is obvious that the same effect can be obtained. For example, in the example shown in FIG. 1, when the partition wall D between the first security area B1 and the second security area B2 is removed to make them one security area,
It is only necessary to remove the jumper wires of the connection terminals T3 and T4 and attach the jumper wires to the connection terminals TA and TB. On the contrary, the same applies to the case where one room is partitioned by a partition or the like and divided into two warning areas.

In the example of the sensor grouping device 2 constructed by using the matrix circuit described in the present embodiment, the information for grouping is provided by attaching the jumper wires to the connection terminals. The present invention is not limited to this configuration, and can have other appropriate configurations. For example, the input terminals X1 to Xn and the output terminal Y1
It is also possible to adopt a configuration in which the correspondence relationship between Ym and Ym is defined using a microprocessor. In this case, the representative signal may be output in response to the sensor output according to a computer program based on appropriate information for grouping, for example, electrical information.

[0019]

As described above, according to the present invention, even if the number of sensors that must be provided in each guard area is significantly different, this can be easily dealt with, and the guard area can be changed, Even if the number of sensors increases or decreases due to the expansion, if the total number of sensors required by this change is within the range of the number of input terminals, this can be easily accommodated, so the hardware can be used efficiently, and it is not necessary or wasteful. It is possible to build a security system with high cost performance.
