Abstract

PURPOSE:To easily discriminate the alarm based on essential abnormalities from that based on operations in a central unit by displaying the discrimination obtained by comparing a counted time with start and end times, and the part concerned with a part issuing the alarm at the time of issuing the alarm. CONSTITUTION:Transmission lines 31-3n connect the central unit CTE 2 and supervisory controllers SCEs 11-1n which have alarm issuing functions. The CTE 2 receives the alarm, and a CRT 4 or a printer 5 displays the alarm and the control situation. The SCEs 11-1n control plural air conditioners 711-71m and 7n1-7nm, and simultaneously supervise and control them partially according to a command from the CTE 2. If ACs 711-7nm develop abnormalities or the operating situation changes, the effect is transmitted as supervisory data to the CTE 2, and the attached CRT 4, the PRT 5, or a display 8 such as character displays displays said situation.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to air conditioning equipment installed in large-scale structures,
4. This invention relates to a method for distinguishing and displaying an alarm generated by maintenance, inspection, or various construction work on managed equipment, etc., from the original alarm.

[Conventional technology]

In large-scale structures such as buildings, factories, and warehouses, monitoring and control equipment for various types of equipment is distributed, and in response to alarms sent from these equipment, warnings are centrally displayed on a central equipment. Warnings are also sent out during maintenance, inspection, and various types of work, so these can also be displayed on the cathode ray tube display or printer in the central unit.

[Problem that the invention seeks to solve]

For this reason, when an alarm display goes off, the staff at the central equipment cannot immediately determine whether the alarm is due to an operation such as maintenance 2 inspection or various construction work, or an actual abnormality, and the staff at the central equipment cannot immediately determine whether the alarm is due to an operation such as maintenance 2 inspection or various construction work, or whether it is due to an original abnormality. The only way to make a distinction is to compare it with a table, etc., which creates a problem that makes it difficult to judge the content of the warning.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention is constructed by the following means.

In other words, when performing an operation that sends out an alarm to a monitored part of a plurality of monitoring and control devices, each of which has monitoring and alarm sending functions and is distributed, the alarm is sent centrally. The start and end time of the operation and the relevant part are registered in the central unit to be displayed, and when an alarm occurs, the central equipment compares the measured time with the start and end time of the operation and compares the relevant part and the part where the alarm occurred. By comparing the above, it is possible to identify whether the problem is caused by the operation, and display based on this identification.

[Effect] Therefore, when an alarm occurs in response to an operation, it is displayed to distinguish it from the original alarm, and it can be immediately determined that the alarm is based on the operation.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to figures showing examples.

Figure 2 is a block diagram of the entire configuration, in which monitoring and control equipment (hereinafter referred to as 5CE) 1 to 11 are distributed in 6D and Pilding premises, etc., and a central computer such as an electronic computer that comprehensively controls them. In addition to the equipment (hereinafter referred to as CTE) 2 provided, a transmission line 3.

It is designed to display F-reports and control status.

Note that each of 5CEt□ to 1n is a plurality of air conditioners (hereinafter referred to as AC) 7.1 to 7□. In addition to controlling Tn□ to 7 nm, these are the areas to be monitored, and CTE2
While performing local control of each individual according to commands from
If an abnormality or a change in the operating status occurs in AC71□~TlllTl, this is sent to CTE2 as monitoring data, and these conditions are sent to CRT4. PR
The information is displayed using a display device such as a T5 or a character display (hereinafter referred to as DP8).

5CE1□~1n are the ACTs targeted for each.
The configuration is determined depending on the type of 11 to 7 nm and the number of devices. Large ones come with CRT4 and PRT5, small computers etc. are used, and small ones come with DP1.
3 is included and uses a microprocessor etc.

In addition, when an operation such as maintenance 1 inspection, repair, expansion work, etc. is performed on any of the monitored parts of each 5CE11 to 1fL, and an alarm is sent from the part as a result, according to the operation schedule, If you use the keyboard (hereinafter referred to as KB) 6 that comes with CTE2 to register the start and end time of the operation and the relevant part in advance as shown in the table below, CTE2 will be able to calculate the time and start operation in response to the occurrence of an alarm. and the end time, and
By comparing the area to be operated and the area where the alarm is generated, it is determined that the alarm is caused by the operation, and a display based on this is displayed on the CRT 4 or PRT 5.

FIG. 1 is a flowchart of the control status by the processor (hereinafter referred to as CPU) in CTE2, where (4) shows registration control, 03) shows display control, and (5) shows (03) based on the previous table. In response to "Register operation schedule" 101 by operating KB6, "Save operation schedule to memory" 1 while the CPU is in CTEZ
Do 02.

Also, in (B), is there a re-report? If J 201 is Y (YES), the time measured by the CPU or the time signal from the outside is compared with the operation start and end times in the memory, and the [During the operation?
J 202 is determined, and if this is also Y, further, by comparing the corresponding monitoring target part in the memory and the alarm generation part, "Monitoring target part during operation?" 203 is determined, and according to this Y. Identifies that an alarm occurs due to the operation, and based on this, displays the "operation alarm display" 211 on the CRT4 or P
Go to Br3.

On the other hand, step 202 or 203 is N (No).
If not, the IF notification due to the actual occurrence of the abnormality is sent, and the "normal alarm display" 212 is performed in the same manner as in step 211.

FIG. 3 shows that in response to steps 211 and 212, the CRT
4 or printed and displayed by PBr3, the year, month, day, 11°, 1st, 12 are displayed based on the timekeeping function, and the time, 13. Status of "W alarm occurrence J14" in response to abnormality, display code 15

Note that these display contents are sequentially stored in the memory, and can be displayed all at once if necessary.

FIG. 4 is a flowchart corresponding to the first factor (B) showing another embodiment.1) The time measured by the CPU or by the time signal from the outside matches the operation start time in the memory. is judged as “operation start time?” 301, and if this is Y (YES), “operation start display for the relevant part” 30
2 is performed under the control of CRT4 and PBr3.

Next, check the match between the measured time and the operation end time in the memory using [Operation end time?]. Judging by J 311, if this is also Y, “operation end display for the relevant part” 3
12 is performed in the same manner as step 202.

Fig. 5 shows an example of a display corresponding to Fig. 4, and shows the start and end times of maintenance and the name of the part concerned in Fig. 3.

Therefore, according to the display on the CRT4, it is possible to immediately determine whether an "alarm has occurred" or "operation is normal" in response to an operation, and the same can be said even if the printed display on the PBr3 is checked immediately or after the fact. It can be easily determined whether or not.

In addition to registration by KH2, each 5CT1, ~1n
It is also possible to provide an input means such as a keyboard for each operation, and use these operations to perform maintenance, inspection, maintenance, etc. from a separate management computer.
The same applies to transferring general maintenance programs including various construction works to CrB2, and CrB2 automatically registers operations accordingly, and displays the displayed contents stored in the memory of CrB2 as a daily report. etc., when printing all at once, items based on operations may be deleted, and displays based on operations may be displayed in different colors.

In addition, when registering, only the start and end times of the operation and the operated part are stored in the memory, while the relationship between the operated part and the monitored part is smoothly stored in the memory as a table, and the CPU registers. The part to be monitored may be determined from a table according to the operated part, and 5CE
I, to 1n can be modified in various ways, such as being similarly applicable not only in the same building, but also in buildings located on the same campus, or in dispersed buildings.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, a warning based on a scheduled operation is displayed in a manner that distinguishes it from an If notification based on an original abnormality. Discrimination can be easily and immediately performed, the possibility of misidentification is completely eliminated, and a remarkable effect can be obtained in various monitoring alarm displays.
