Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiver interlocking system.

[0002]

2. Description of the Related Art FIG. 2 is a system diagram showing a conventional example of a receiver interlocking system. From the receiver that receives the fire signal from the interlocked device such as fire detector, send the device interlocking data that shows the interlocking control pattern of the interlocking device such as fire door and smoke prevention equipment, and connect to other receivers. As an inter-receiver interlocking system that interlocks the interlocking device based on the device interlocking data, a system as shown in FIG. 2 has been conventionally proposed. The inter-receiver interlocking system includes a first receiver 1a to which an interlocked device such as the sensor 2 is connected,
Although it has a second receiver 1b to which the interlocking device 3 is connected, conventionally, the device interlocking data is directly transmitted between the first receiver 1a and the second receiver 1b. Since they cannot be exchanged, a relay device is attached to each receiver, and device interlocking data is exchanged between the receivers via the relay device. That is, in the conventional example, the first repeater 5a is transmission line connected to the first receiver 1a, the second repeater 5b is transmission line connected to the second receiver 1b, and the first repeater 5a is connected. 5a and the second repeater 5b are connected by a signal line. However, the device-interlocked data is exchanged between the repeaters by a non-voltage contact output. Conventionally, a maximum of 128 contact outputs can be assigned to one repeater. Incidentally, both the sensor and the interlocking device are actually connected to each receiver, but for convenience of explanation, the interlocking device connected to the first receiver 1a and the second receiving device are connected. Illustration of the sensor connected to the machine 1b is omitted.

In the inter-receiver interlocking system having the above structure, when the detector 2 connected to the first receiver 1a detects a fire and outputs a fire signal, the first receiver 1a causes the fire to occur. At the same time as receiving the signal, the device-interlocking data is sent from the first repeater 5a to the second repeater 5b, and the device-interlocking data is transmitted to the second receiver 1b. The second receiver 1b interlocks with the interlocking device 3 connected to itself based on the device interlocking data.

Further, as described above, it is also possible to interlock control the interlocking device connected to the first receiver 1a from the second receiver 1b.

[0005]

However, in the inter-receiver interlocking system having the conventional structure, as many relays as the number of the contact outputs for interlocking control are required, which is very costly and the interlocking control pattern is required. When adding or changing, it is necessary to change the wiring, and it is very difficult to add or change the interlocking control pattern. In addition, when there are a plurality of repeaters, the space for installing the repeaters becomes a problem that cannot be ignored.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a receiver interlocking system which does not require a repeater.

The present invention will be described below with reference to the drawings showing its embodiments. The same components as those in the conventional example are designated by the same reference numerals.

FIG. 1 is a system configuration diagram showing a receiver interlocking system according to an embodiment of the present invention. As shown in Figure 1,
The inter-receiver interlocking system according to the embodiment of the present invention detects a fire and outputs a fire signal, for example, the detector 2
And a first receiver 1a to which a transmitter or the like is connected, and a second receiver 1b to which the interlocking device 3 related to fire, such as a fire door, smoke prevention equipment, or alarm equipment is connected, and the fire signal It comprises a central unit 4 for receiving the received signal from the first receiver 1a and transmitting device interlocking data for interlocking control of the interlocking device 3 to the other second receiver 1b. . In reality, both the sensor and the interlocking device are often connected to each receiver, but for convenience of description, the interlocking device connected to the first receiver 1a and the interlocking device are connected to each other. 2 The linked devices such as a sensor connected to the receiver 1b are not shown. The inter-receiver interlocking system of the embodiment of the present invention can also interlock and control interlocking devices connected to the first receiver 1a from the second receiver 1b.
The details will be described below. In the embodiment of the present invention,
The linked device will be described by using the "sensor 2" as a representative.

The central unit 4 has a central processing unit 4a for registering device interlocking data relating to interlocking control patterns of a plurality of sensors 2 (devices to be interlocked) and a plurality of interlocking devices 3.
It is composed of a display means 4b such as a CRT for displaying the registration screen of the device interlocking data and fire information and the like, and a data selecting means 4c such as a mouse and a keyboard for setting the device interlocking data. Between the central processing unit 4a and the first receiver 1a and between the central processing unit 4a and the second
The receiver 1b is connected with a communication cable typified by RS232C, etc., and data can be exchanged between them.

As described above, the central processing unit 4a registers the interlocking control pattern of each sensor 2 (interlocked device) and each interlocking device 3 as device interlocking data. In the inter-receiver interlocking system of the embodiment of the present invention, the registration operation of the device interlocking data is performed on the screen of the CRT or the like. That is, when registering the device interlocking data, the central processing unit 4a causes all the sensors 2 (interlocked devices) and interlocking devices 3 that form the inter-receiver interlocking system to be displayed on the display means 4b. On the screen, the desired specific sensor 2 and the interlocking device 3 to be operated when the specific sensor 2 detects a fire are selectively set by the data selecting means 4c. Has become. Thereby, the specific sensor 2 and
The interlocking device 3 to be interlocked with the fire detection of the specific sensor 2 is associated on the screen of the display means 4b. At this time, the "specific sensor 2" and "the specific sensor 2" are associated with each other.
Of the interlocking device 3 which should be interlocked with the fire detection of "the device 2" and the interlocking device 3 showing the interlocking control pattern of the sensor 2 and the interlocking device 3 by accumulating in the memory of the central processing unit 4a. It is designed to register linked data. In this way, by linking the interlocking devices 3 to be interlocked with all the sensors 2, the device interlocking data for all the sensors 2 (interlocked devices) is registered. Further, the addition or change of the device interlocking data can be similarly performed on the screen.

As described above, since the central device 4 stores all the device interlocking data relating to the interlocked devices such as the sensor 2, the interlocked device and the interlocked device 3 are stored.
It becomes extremely easy to manage the interlocking control pattern with.

The inter-receiver interlocking system of the embodiment of the present invention is
For example, it operates in the order of to shown below. A specific sensor 2 (linked device) detects a fire and outputs a fire signal. The first receiver 1a to which a specific sensor 2 is connected
(Or the second receiver 1b) receives the fire signal and displays a fire. The first receiver 1a (or the second receiver 1b) transmits the fire signal to the central processing unit 4a. The central processing unit 4a specifies the sensor 2 that has output the fire signal from the contents of the fire signal, and searches the memory for desired device-interlocked data regarding the specified sensor 2. While displaying a fire on the screen of the display means 4b,
When the desired device interlocking data regarding the specified sensor 2 is retrieved, the device interlocking data is sent to the second receiver 1b (or the first receiver 1a). The second receiver 1b (or the first receiver 1a)
Controls the operation of the corresponding interlocking device 3 connected to itself based on the received device interlocking data.

Although the inter-receiver interlocking system in this embodiment is composed of two receivers 1a and 1b, it goes without saying that the inter-receiver interlocking system may be composed of three or more receivers. In this case, the device interlocking data retrieved by the central processing unit 4a is distributed and transmitted for each receiver. Further, since the central device 4 manages all of the devices, it is necessary to add a linked device such as the sensor 2 or the like, an interlocked device 3 or a receiver to expand the system. This can be easily dealt with by rewriting and changing the data stored in the central unit 4.

[0016]

According to the present invention configured as described above, a repeater, which has been indispensable in the past, becomes unnecessary, and space saving can be realized by the amount of the repeater. Further, by registering the device-interlocked data on the screen, the registration operation of the device-interlocked data becomes extremely easy, and addition and change of the device-interlocked data become extremely easy.
