Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abnormality detecting method for detecting various abnormal phenomena occurring in building equipment.

[0002]

2. Description of the Related Art Generally, there are various building facilities such as outdoor parking facilities, power generation facilities, factories, office buildings and condominiums. Traditionally,
As a means of detecting abnormal phenomena in building equipment, it is generally known that sensors are individually arranged for various equipment installed in building equipment and the abnormality is detected by the detection function of the sensor itself. When the sensor detects an abnormality, only the device that is the source of the abnormality is forcibly stopped to prevent a disaster, such as a fire, resulting from this.

[0003]

However, in the above-mentioned conventional abnormality detecting method, since the sensor is arranged only for the equipments installed in the building equipment and the abnormality of the equipments is individually detected, Abnormalities such as wiring equipment (bus ducts, cables, etc.) that connect individual devices and relays could not be detected. In the conventional method,
Even if an abnormal phenomenon due to a failure of individual equipment can be detected,
It was not possible to detect up to the location where the anomaly occurred (the location of the equipment that caused the anomaly). Furthermore, in some equipment, if the bolts and screws are loosened, the noise may increase and may not actually be detected as a failure.Therefore, means for detecting abnormal phenomena before such a failure have been taken. There wasn't.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an abnormality detecting method capable of totally detecting an abnormal phenomenon of building equipment over a wider range.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and assumes various abnormal phenomena occurring in building equipment, and builds a sensor for detecting the abnormal phenomena. The detection data sent from each sensor is received by the controller, and the detection data is compared with each reference data stored in advance in the controller for comparison. Based on the result and the arrangement position of each sensor, an abnormal phenomenon occurring in the building equipment and an abnormal place are detected.

[0006]

In the method for detecting an abnormality in building equipment according to the present invention,
On the basis of the detection data from the sensors respectively arranged on the assumption of various abnormal phenomena occurring in the building equipment, the abnormal phenomenon occurring in the building equipment and the location where the abnormality occurs are detected.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a conceptual diagram for explaining an abnormality detection method for building equipment according to the present invention. In the figure, reference numeral 1 represents an overall image of building equipment, and various sensors 2, 3, 4, 5 are arranged inside the building equipment 1. These respective sensors 2, 3, 4 and 5 are respectively arranged at predetermined locations of the building equipment 1 in consideration of various abnormal phenomena occurring in the building equipment 1, and examples of this point will be given later. Will be described in detail.

Data lines 6 are derived from the individual sensors 2, 3, 4, and 5, and these data lines 6 are all connected to a controller 7. The controller 7 includes sensors 2 arranged in the building equipment 1,
Corresponding to 3, 4, and 5, reference data serving as a reference for determining an abnormal phenomenon is stored in advance. Further, a monitor 9, an external alarm device 10, and a data storage device 11 are connected to the controller 7 via a signal line 8.

Here, the sensors arranged in the building equipment 1 and the places where the sensors are arranged will be described. First, as the types of sensors, for example, a temperature sensor 2 using infrared rays, a sound sensor 3 used when measuring a noise level, a vibration sensor 4 capable of extracting vibrations by frequency, and an odor level are measured. The gas sensor 5 that can be used is one example.

The various abnormal phenomena occurring in the building equipment 1 include not only the failure of the equipment itself, which has been the object of the related art, but also, for example, abnormal overheating of the wiring equipment connecting the equipment. Examples thereof include abnormal noise and abnormal vibration of facility equipment due to loosening of bolts and the like, and abnormal odor due to overheating of facility equipment or wiring equipment.

Assuming such an abnormal phenomenon, the above-mentioned sensors are arranged at predetermined locations of the building equipment 1, for example, on the wiring path of the wiring equipment, at the connection portion with the equipment, and inside or near the equipment. To be done. At that time, the sensors to be installed should have abnormal phenomena expected at each location, such as temperature rise due to overheating of wiring equipment, increase in noise level and vibration due to loosening of bolts, etc. It is appropriately selected according to the level increase.

It should be noted that each of the various sensors 2, 3, 4, 5 is not provided in the building equipment 1, but only one sensor is provided.
The required number is arranged based on the selection result described above, and the arrangement positions thereof are also arranged at the above-mentioned predetermined positions on the assumption of an abnormal phenomenon that may occur in the building equipment 1. It is a thing.

In this embodiment, the system as described above detects an abnormal occurrence of the building equipment by the following method. First, the sensors 2, 3 arranged at predetermined locations of the building equipment 1,
Detection data from 4 and 5 is sent to the controller 7 through the data wiring 6 according to the detection function. The controller 7 receives the detection data sent from the sensors 2, 3, 4, 5 and compares the detection data with the reference data stored in advance for each type. For example, since the detection data sent from the temperature sensor 2 is of course data relating to temperature, the controller 7
Correspondingly, the reference data regarding temperature is taken out,
Both data are compared.

Next, if the detected data sent from the sensor in the above comparison result exceeds the allowable range of the reference data, the controller 7 judges that an abnormality has occurred in the building equipment 1, and immediately detects the abnormality. The detection data from the sensor and the position of the sensor are displayed on the monitor 9. As a result, an abnormal phenomenon that has occurred in the building equipment 1, such as an increase in temperature or noise, is detected from the detection data displayed on the monitor 9, and the location of the abnormality is detected from the position where the sensor is displayed on the monitor 9. Is detected.

When the external alarm device 10 is connected to the controller 7 as in the present embodiment, an alarm signal is sent to activate the external alarm device 10 to generate an alarm sound when an abnormality occurs in the building equipment 1. You can also notify the guards by.

The detection data is periodically sent from each of the sensors 2, 3, 4, 5 arranged in the building equipment 1, and the detection data received by the controller 7 is used as a reference. If the detected data is within the allowable range of the data, the detected data is stored in the data storage device 11 at any time, and the controller 7 itself continuously monitors the building equipment 1 for the occurrence of an abnormality.

[0017]

As described above, according to the abnormality detecting method of the present invention, the sensors are respectively arranged at predetermined locations of the building equipment in consideration of various abnormal phenomena occurring in the building equipment, and the respective sensors are provided. Since the abnormal phenomenon and the place where the abnormality occurs in the building equipment are detected based on the detection data sent from the equipment, not only the abnormality (fault) of the equipment equipment installed in the building equipment, but also the wiring connecting those equipment It becomes possible to detect abnormalities in building equipment comprehensively over a wider range than before, such as equipment abnormalities (overheating phenomenon, etc.) and equipment noise abnormalities due to loosening of bolts, etc. Further, in addition to the abnormal phenomenon that has occurred in the building equipment, even the abnormal place can be detected, so that it is possible to deal with a sudden occurrence of the abnormalities in the building equipment more quickly and appropriately than in the past.
As a result, it can be expected that the safety of building equipment against a disaster such as a fire is improved.
