Description

[Detailed description of the invention] The present invention connects a plurality of relay panels in parallel to a central control device,
This invention relates to an L-wedge device in which an abnormality such as a fire is determined from the detection data of seven LTI sensors connected to each relay board 1ii by a plurality of analog sensors (1 signal connected to a J line).

In the past, a horn such as a warm-polished machine was connected to the signal line to the relay board Z, and multiple relay boards were connected to the transmission line of the central control equipment (defense port). , l This monitoring device - [1, , -11, polling from the central control unit] first calls the middle 1 board, and then calls the Similarly, the detection gap of the analog sensor is specified for medium heat control 4: device 7). go to village,
Repeat the sampling of each medium narrow 1 (sequentially to the mouth IJ, medium i1: ?I3 leaf extension) and 2 narrow sensor 1 no.

However, with this monitoring method, multiple analog logs are collected on the board 11, and the central control unit (central control unit) → ] - This means that the relay board is called. When there are a large number of analog sensors, it takes J
There was a problem that the lean shilling cycle became longer.
.

On the other hand, let's use another monitoring method to set the 4 non-bringing period to 0 - C1 each medium fog! The detection data from the non-recording temperature analyzer L is individually non-bringed, and when it is determined that there is an abnormality in the sampling temperature, an abnormality flag is set at J3 on the relay board, and the central control unit , only monitors the flag status of the relay board, and when the intermediate fire control device detects an abnormal flag, it detects the data reception status from the relay board that generated the abnormal flag, and checks the raw silk board that generated the abnormal flag. , "; unilaterally transmits the limbed detection data to the central control unit [6], and (transmits the detected data to the central control unit g) 'Cf -The entire process was completed.

However, this monitoring method (32), 1 relay panel

If A is interrupted, then central control! ! (Fixed in the reception standby state for data reception from the relay board with the abnormality flag turned 9 until the data transmission is completed, and the central controllers i and 7 hold it.) There was a problem that the control function was impaired and -C occurred.

The present invention was made in view of the problems of the 41st Confucian Song Dynasty, and it shortens the → humbling circumference 111J of detection data by analog sensors, and also detects abnormalities in the relay board and sends them to the central control unit. The purpose of this invention is to provide a supervising station that can quickly perform data transmission processing without depending on the state of the relay qt.

To achieve this objective, the present invention provides a central control system.

Each of the relay boards connected in parallel with one transmission line from the station is equipped with a function to generate an abnormality flag when detecting the winnower 11- by sequentially sampling the detection signals from the plurality of analog sensors. In the steady monitoring state, the central control unit only refers to the flag information of each relay board, and when it detects an abnormal flag, it interrupts the relay 'AA' that is generating the abnormal flag and uses polling from the central control unit 'I'. Announcer 1 of the relay board, which determined the transfer, inputs "Il"r output a'-event as if polling Grenry.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

Historically, in order to avoid transmitting analog sensor detection data with immediate commands from the central government, even if there was a relay board, the data reception process could not be done between 11 and 1. , the central control unit can smoothly perform the process of determining whether there is a fire or the like and the operation of the various control equipment 11 associated with the fire.

Further, when another control device 6 becomes abnormal, it is possible to stop the transmission process Jj1 at any time and perform control processing to deal with the normal state of the other control device 6.

It should be noted that the threshold value of the setting circuit 15 provided in the relay board 81) shown in FIG. Therefore, each analog sensor-'J9a-9

The flag information shown in Figure 1C is imitated as an abnormality flag, and this abnormality flag is detected by the central control unit. 11 commands, the relay board receives an interrupt command (J), switches to the process according to the commands from the central controller, and sequentially receives an interrupt command from the central controller. In order to be able to send back the detection data of the sensor, it is necessary to set up a mid-phase board and send it to the central controller in 7 hours.
4. It is possible to input the detection data of the No. 1 input port that is connected to the saw relay QH and input the detection data of the No. can.

Historically, the detection data from the analog sensor with 3 = 17 in the central control device was detected by the address code generated at the relay panel. [Because J Glenn's polling causes line 4f, an error occurs in the relay board and the detection data is not transmitted normally.
'The central control unit is not fixed in the reception standby state, and operates normally. Never.

Furthermore, because the interrupt command from the medium-heat control device can increase the roasting data of one person, Azulog Lenz, by +5T, the manual operation of the central control device allows a specific Noah III/) Lenz to be roasted. You can also specify the address code to read the detected data.
