Description

[Detailed description of the invention]

[Industrial Application Field] The present invention is designed to detect alarms generated when maintenance, inspection, or various construction work is performed on air conditioning equipment, various management equipment, etc. installed in a large-scale structure. The present invention relates to a method of displaying a warning by distinguishing it from an original warning. [Prior art] In large-scale structures such as buildings, factories, and warehouses, devices for various facilities are distributed and arranged.
These devices are equipped with an alarm sending function, and the central device centrally displays alarms.Alarms are also sent during maintenance, inspections, and various construction works, so this is also a central device. It is displayed on a cathode ray tube display or a printer. [Problem to be solved by the invention] For this reason, when an alarm is displayed, the person in charge of the central equipment cannot determine whether it is due to maintenance, inspection, various construction operations, etc., or whether it is due to an original abnormality. This cannot be done immediately, and the only way to make a determination is to compare each operation with a schedule, etc., creating a problem in which it is difficult to judge the content of the alarm. [Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention is constituted by the following means. In other words, when an operation is performed to send out an alarm to one of a plurality of devices, each of which has an alarm sending function and is arranged in a dispersed manner, the start of the operation and the central device that centrally displays the alarm are sent. The end time and monitoring points related to the operation are registered in advance, and when an alarm occurs in the central device, the alarm is calculated by comparing the measured time with the start and end time of the operation, and comparing the related monitoring point with the alarm generation point. It is assumed that the object is identified as an object to be operated, and a display is performed based on this identification. [Function] Therefore, when an alarm is generated in response to an operation, it is displayed and distinguished from the original alarm, and it can be immediately determined that the alarm is based on the operation. [Example] Hereinafter, details of the present invention will be explained with reference to figures showing examples. Figure 2 is _a block diagram of the entire configuration _.
are arranged in a distributed manner, and a central equipment (hereinafter referred to as CTE) 2 such as a computer that comprehensively controls them is provided, and transmission lines 3 1 to ₁ are connected between each ACE ₁ to 1 _o and CTE 2. 3 connected by _o ,
CTE2 performs general control by transmitting and receiving data via transmission lines _{31 to 3o} between CTE2 and ACE11 to _1o , while each of _ACE11 to _1o has an alarm sending function. The CTE 2 receives the alarm, and displays the alarm and the control status using a cathode ray tube display (hereinafter referred to as CRT) 4 or a printer (hereinafter referred to as PRT) 5. Note that each ACE _{1 1} to 1 _o is composed of a plurality of air conditioners (hereinafter referred to as AC) 7 ₁₁ to 7 _1n to 7 _o1 to 7 _on and local controllers (hereinafter referred to as DCT) 8 ₁ to 8 _o . AC7 ₁₁ - 7 _on are the monitoring points, and DCT 8 ₁ - 8 _o performs local control individually according to commands from CTE 2, and detects abnormalities or operating conditions at each monitoring point. If a change occurs, this is sent to the CTE 2 as an alarm or monitoring data. In addition, when maintenance, inspection, repair, expansion work, etc. are performed on any of the ACE11 _{to 1o} , and as a result, an alarm is sent from the relevant part, the operation shall be carried out according to the operation schedule. If you use the keyboard (hereinafter referred to as KB) 6 attached to CTE 2 to register the operation start and end times and related monitoring points in advance as shown in the table below,
In CTE2, when an alarm occurs, it is identified that it is caused by an operation by comparing the measured time with the operation start and end times, and the related monitoring target point and the alarm generation point. The display is based on the CRT4 or PRT5.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, an alarm based on a scheduled operation is displayed while being distinguished from an alarm based on an original abnormality, so that it is possible to distinguish between an alarm based on an original abnormality and an alarm based on an operation. can be carried out easily and immediately, the possibility of misidentification is completely eliminated, and a remarkable effect can be obtained in various monitoring alarm displays.

Claims (1)

[Claims] 1. When performing an operation to send an alarm to any one of a plurality of devices, each of which has an alarm sending function and which are arranged in a distributed manner, the operation is sent to a central device that centrally displays the alarm. Start and end times and monitoring points related to the operations are registered in advance, and when an alarm occurs in the central device, comparison of the measured time with the start and end times and comparison between the monitoring point and the alarm generation point is performed. A method for identifying and displaying alarm contents, characterized in that it is identified by comparison that the operation is caused by the operation, and a display is performed based on the identification.
