DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the basic configuration of a fire receiver A having an automatic registration function of a disaster prevention terminal according to the present invention. In this fire receiver A, various disaster prevention terminals are assigned to the main CPU unit 2 via a plurality of terminal processing units 1 (1a to 1d), and a plurality of operation panel units 3 (3a) assigned by function. ~ 3f) via the operation panel 4
Are connected to the address and data buses, respectively. Further, the main CPU section 2 is connected to a system terminal device registration memory 5 composed of an EEPROM or the like, and can store individual data set in each terminal device processing unit 1.

Here, the terminal processing unit 1 is connected to various disaster prevention terminals such as a fire detector 10, a smoke preventive device 20, and various alarm devices 30 provided in the monitoring line L. In addition, the operation panel 4a, which has an operation indicator light for displaying the operation status of each disaster prevention terminal, and the control status of each district (for example, each floor) with respect to the fire occurrence in the building, etc. District lights 4b to display, sound bell 4c to generate alarm sound,
A trouble display section including a unit registration switch 4d for storing individual data of each terminal processing unit 1 in the system terminal registration memory 5 by the operation, a liquid crystal screen for displaying a registration abnormality of the system terminal registration memory 5, an LED, and the like. 4e, a registration monitor display unit 4f for displaying detailed data of registration abnormality and monitoring status of each disaster prevention terminal.

In each of the terminal processing units 1,
Unique data for multiplex transmission within the panel, unit type (fire detector, smoke control device, various alarm devices, fire alarm, common smoke control device, etc.), individual data such as monitoring line number, etc. It is designed to be set by connecting a dip switch or a jumper wire provided in the unit of No. 1 and incorporated into the fire receiver A. The addresses assigned to each terminal device processing unit 1 are the fire detector 10 and the smoke control device 2
0 and various alarm devices 30 are prioritized in order, for example, 1, 2, and 3 are assigned in order from the lowest numbered address (for example, when the fire detector processing unit is not connected, The address of the smoke control equipment processing unit may be 1.).

With the above structure, the fire receiver A according to the present invention.
Automatically registers the disaster prevention terminal, and thereafter controls the disaster prevention terminal based on the registration data. The basic operation will be described below. Normally, the terminal device processing unit 1 monitors each disaster prevention terminal device and notifies the main CPU unit 2 of the information when an abnormal signal is received from these disaster prevention terminal devices. On the other hand, in the main CPU unit 2, the operation status is displayed on the operation display unit 4a via the operation panel unit 3 in accordance with the operation of the fire detector 10, the smoke proof device 20, or the like.
The district lights 4b are turned on and the acoustic bell 4c is rung so that various troubles in the monitoring line can be understood.

In the main CPU section 2, when the unit registration switch 4d is operated when the power is turned on or the like, all the terminal processing units 1 which can be incorporated are sequentially accessed by polling processing, and each terminal is processed. Setting data such as an address, a unit type, and a monitoring line number preset in the instrument processing unit 1 is automatically registered in the system terminal instrument registration memory 5.

At this time, referring to the address of the terminal processing unit 1 registered in the system terminal registration memory 5, if the registration is incorrect, the trouble display section 4 is displayed.
The registration abnormality of the registration data is displayed in e (Claim 1). If it is determined that the registration is wrong, it means that there is a duplicate registration of the address number between the fire detector or smoke prevention equipment processing unit and the alarm equipment processing unit, and the fire detector or smoke prevention equipment. This is when an address number that is younger than the lowest address number assigned to the device processing unit is missing. Here, the determination of duplicate registration is performed between different terminal processing units 1, but the same processing is also performed between the same terminal processing units 1.

An example of registration in the system terminal registration memory 5 is shown in FIG. (A) is an example of duplicate registration, in which the terminal device processing unit 6 has an address number “3” and the terminal device processing unit 10 has an address number “4”.
(B) is an example of a missing number, and the address numbers "1" and "2" that are younger than the youngest assigned address number "3" are missing numbers.

When the trouble display section 4e displays a registration error, the address of the terminal processing unit 1 is set correctly, or the terminal processing unit 1 of the correct type is installed and the unit registration switch 4d is operated again. Registration in the system terminal registration memory 5 is performed. However, when there is an error due to a missing number, the monitoring process is continued only for registered data, and when the terminal device processing unit 1 with the missing address number is incorporated, the unit registration switch 4e is operated. Alternatively, the monitoring control processing may be performed on the incorporated terminal processing unit 1 without performing the above.

When no registration abnormality is displayed on the trouble display section 4e, the main CPU section 2 performs monitoring control processing of each disaster prevention terminal for the registered data. At this time, when data is transmitted once with each terminal processing unit 1 in the initial processing, for example, the number of monitoring lines actually provided in the terminal processing unit 1 is the monitoring line registered in the system terminal registration memory 5. If the numbers are different,
The supervisory control process may be performed by the number of lines with the larger number.
