Abstract

PROBLEM TO BE SOLVED: To provide an abnormality detection device which is easily installed, can detect the occurrence of abnormality without contact and also can be repetitively used, when a light emitter is replaced after the detection of abnormality by using a pawl member which is actuated by the state change of a detection object and the light emitter which emits the light when it is depressed by the pawl member. SOLUTION: A light emitter 1 is fixed to a casing 6 of a sensor main body via an upper cover 5, and a water-absorbing sheet 7 is used to prevent a water absorbing swelling member 3 from leaking to a water-absorbing port 4. A pawl member 2 can move upward by the swelling of the member 3. When an inundation phenomenon occurs, the water enters through the port 4 and reaches the member 3 through the sheet 7. The member 3 can swell only in the upper direction, and accordingly the member 3 swelled by the water pushes up the member 2 and bends the light emitter 1 to make it emit light and to detect the inundation phenomenon. Furthermore, this abnormality sensor itself can be used repetitively, when the member 3 and the light emitter 1 are replaced with new ones respectively, after the inundation phenomenon has been detected.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, one embodiment of a water intrusion detection sensor among the abnormality detection sensors of the present invention will be described with reference to the drawings. 1 (A) and 1 (B) are longitudinal sectional views of one embodiment of the water intrusion detection sensor of the present invention. (A) shows a normal state (before flooding), and (B) shows a state at the time of flooding. In the figure, 1 is a luminous body,
2 is a nail member, 3 is a water-absorbing swelling material, 4 is a water-absorbing port,
The luminous body 1 is fixed to a casing 6 of the sensor main body with an upper lid 5. A water absorbing sheet 7 is provided so that the water absorbing swelling material 3 does not leak to the water absorbing port 4. The claw member 2 is provided so as to be able to move upward by swelling of the water-absorbing swelling material 3. The water immersion detection sensor of the present invention is installed in a state where it is desired to monitor water immersion or liquid leakage with the water suction port 4 facing downward in the state of FIG. It may be fixed to the installation floor as needed, but need not be particularly fixed. When water is immersed at this location, water enters through the water absorbing port 4 and passes through the water absorbing sheet 7 to reach the water absorbing swelling material 3. Since the water-absorbing swelling material 3 can only swell upward, the water-absorbing swelling material 3 swelled with water
Pushes up the claw member 2 to be in the state (B), and bends the luminous body 1 to emit light, thereby detecting the inundation.

The swelling material used in the immersion detecting sensor of the present invention may be any material that swells as far as the claws can be moved when absorbing water. A water-absorbing polymer is preferred from the viewpoint of swelling property and ease of replacement after water immersion, and a water-absorbing polymer such as starch, cellulose, or synthetic polymer can be used without any particular limitation. Vinyl alcohol copolymer, acrylic acid polymer, acrylic acid
Synthetic polymer materials such as acrylamide copolymers and modified polyethylene oxides are preferred. Specifically, for example, Sumikagel (trade name, manufactured by Sumitomo Chemical Co., Ltd.), Aquaric (trade name, manufactured by Nippon Shokubai Chemical Co., Ltd.), Sunwet (trade name, manufactured by Sanyo Chemical Industry Co., Ltd.), Arasorb (trade name, Arakawa Chemical Industry Co., Ltd.), Aqua Keep (trade name, manufactured by Iron and Steel Chemical Industry Co., Ltd.), Poise SA (trade name, manufactured by Kao Corporation) and the like. Those having a water absorption capacity of 500 times or more in pure water are particularly preferable. Further, as the luminous body used for the water immersion detection sensor of the present invention, a phosphor is preferably used, but is not limited to this, and any luminous body that emits light when pressed and deformed by the claw member may be used. Can be. Preferably, a phosphor (for example, Lumicalite (trade name, manufactured by Nippon Chemical Emission Co., Ltd.) or the like) that emits fluorescence when two kinds of liquids enclosed by being folded are mixed is used.

The main body of the immersion detection sensor of the present invention is made of ABS.
(Acrylobutadiene styrene) resin material, stainless steel,
Aluminum or aluminum alloys are particularly preferred. The shape of the main body can be selected according to the installation location and the like, such as a prism or a cylinder. The lower part of the main body has a water inlet, and the size, shape, number, and the like of the water inlet can be appropriately selected according to the situation of inundation to be detected, the installation location of the sensor, the type of swelling material, and the like. FIG. 1C shows a bottom view of the above embodiment. As shown in FIG. 1 (C), an arbitrary shape can be selected as necessary, such as forming a groove from the side surface at the water inlet on the bottom surface. In the main body casing, a swelling material is sealed so as not to leak into the water suction port. Further, as a material of the claw member having a claw member operated by swelling of the swelling material, for example, an ABS resin material, aluminum or the like is preferable. Both ends of the luminous body are fixed to the main body so as to cross the upper part of the main body and just above the claws.

The immersion detecting sensor of the present invention is economical if the swelling material and the luminous body are replaced by new ones after detecting the immersion, since the sensor itself does not need to be replaced every time the immersion is detected. Also,
The luminous body and the swelling material can also be easily obtained by removing the upper lid.

As an abnormality detection sensor of the present invention or as an alternative to the detection sensor, the mechanism for operating the claw member is not limited to the expansion and contraction of the swelling material in the above-described example of the immersion detection sensor. Any type, such as pressure, may be used as long as the light emitting body can emit light with the claw member. For example, in the case of spring pressure, in normal times, the spring is contracted and held with a stopper, and the stopper is released by a change in the state of the detection target at the time of abnormality, and the stopper is released by this state change A mode in which the spring extends to cause the light emitting body to emit light can be considered.
In the case of air pressure, a mode in which the claw member is momentarily pushed up by the air pressure of the compressor to cause the light emitter to emit light is possible. When these spring pressures or pneumatic pressures are used, the replacement after the abnormality is detected may be performed only by the light emitter, and there is no need to replace the member that operates the claw, such as the swelling material in the above-described example of the immersion detection sensor.

The abnormality detection sensor of the present invention can emit light due to an abnormality such as an increase in the concentration of chlorine gas, an increase in the concentration of carbon dioxide gas, or an increase in temperature by means of the various operating mechanisms described above. It can be used to detect cable fire, lack of oxygen in a room, abnormal temperature, etc. When detecting a temperature abnormality, it is preferable to operate the claw member by a temperature change or a pressure change due to the temperature change or expansion and contraction of the metal, but according to the expansion and contraction of the metal,
This is more preferable because the metal expands as it is due to abnormal temperature and operates the claw member. Such metals include
Needless to say, a crystal structure having a large expansion / shrinkage ratio is preferable. The illuminant, the main body, and its preferable aspects of the various abnormality detection sensors of the present invention are the same as those described for the waterlogging detection sensor of the present invention.

An abnormality detection device according to the present invention includes an abnormality detection sensor as described above, light detection means for detecting light emission of the abnormality detection sensor, and signal processing means for detecting an abnormality in a sensor installation location based on the light detection result. Having. Examples of the light detection means that can be used in the abnormality detection device of the present invention include image input means such as a black and white camera and a color camera. Illumination is usually required to acquire hue data by a color camera or the like in a dark place, but in the abnormality detection device of the present invention, the abnormality detection sensor emits light by itself when an abnormality occurs, so the monitoring location is rented. There is no need to use lighting to acquire image data even in dark places such as
It can be easily installed and used in bright places, dark places, indoors and outdoors.

The signal processing means in the present invention recognizes light emission of the sensor from the light detection result and detects an abnormality. For example, the inside of the light detection processing area including the detection sensor is constantly monitored by the light detection means, and the brightness and the hue are changed in the changing portion where the color and the brightness may change and in the background portion where the change does not occur. An abnormality can be detected by comparing the average values of Which data of luminance or hue is used and how can be selected depending on the brightness of the installation location of the sensor, the color used as the background, and the emission color of the light emitting body. When the sensor is installed in a dark place, usually, any of luminance, hue, or a combination thereof can be suitably used, and hue is used for determining the area of the changing part and the background part, and luminance data is used for the comparison judgment. It is preferable to use them. In the case of light,
Data that can be accurately compared is selected according to the combination of the background color of the light detection processing area and the emission color of the sensor and the degree of brightness. This signal processing means will be described in more detail in the following description of the embodiment of the abnormality detection system.

Next, as an embodiment of the abnormality detection system of the present invention, an example of a flood detection system will be described with reference to FIGS. FIG. 2 is a block diagram showing a configuration of an example of the water intrusion detection system of the present invention. In the figure, 10 is FIG.
, A camera, 100 is a signal processing means, 110 is a general public line, 120 is a modem,
Reference numeral 30 denotes a center system. Sensor 10, camera 2
0 and the signal processing means 100 are in a rental room for monitoring inundation,
The center system 130 is installed in a management center that remotely manages monitoring points collectively. The information processed by the signal processing means 100 based on the image data acquired by the camera 20 is sent to the management center side via the public line 110 at the time of detecting inundation, converted by the modem 120 and taken into the center system 130. Is converted into a visually recognizable form and displayed on the display. FIG. 3 shows a flow of processing in the inundation detection system having the configuration of FIG.
This will be described with reference to the block diagram of FIG. The image data input to the camera 20 is digitized by the A / D conversion unit 30,
The data is sent to the processing area determination unit 50 through the video switching unit 40. The processing area determination unit 50 extracts a region including the sensor 10 from image data acquired by the camera 20 based on predetermined information, and the luminance extraction unit 60 extracts a luminance (Y) signal for each pixel in this region. And outputs the result to the digitization processing unit 70.

FIG. 4 shows a block diagram of the processing in the numerical processing section 70. First, the numerical information processing unit 70 receives, from the window creation unit 71, the area information of the changing part and the background part in the light detection processing area extracted by the processing area determination unit 50 described above. The areas of the changing portion and the background portion are determined in advance by a change in the color (R, G, B) signal when the sensor emits light. In the average value calculation unit 73, the luminance extraction unit 60
The average value α of the luminance signal for each pixel of the changing portion and the average value β of the luminance signal for each pixel of the background portion are obtained from the input luminance value and the area information input from the window creation section 71. Β is output to the reference value determination unit 74 and the illuminance determination unit 76.

FIG. 5 shows the data extraction and the calculation of the average value of the luminance signal. In FIG. 5A, 10 is a sensor,
Reference numeral 20 denotes a camera, X denotes a light detection processing area determined by the processing area determination unit 50, and Y and Z denote window creation units 71.

The inside of the monitoring frame Y including the sensor 10 is a changing portion, and the inside of the reference frame Z is a background portion. L is the distance from the camera 20 to the sensor 10 and performs light detection processing in the range of the angle 2θ. (B)
2 shows an enlarged and schematic part of the processing area X. Each square indicates a pixel in the processing area X, and the luminance extraction unit 60 extracts luminance data for each pixel. Average value calculation unit 73
From the luminance data of each pixel and the information of the set frame, 1 in the monitoring frame Y is set to the average coarse luminance α and the reference frame Z.
The average β of the brightness of one pixel in the pixel is calculated, and the reference value determination unit 74
And to the illuminance determination unit 76. The data of the pixel at the boundary over the two regions is not included.

After calculating the average value, the reference value determination unit 74 calculates | α−β | as the reference value A for determination from the input α and β as shown in FIG. Output to the judgment unit 80. The illuminance determination unit 76 obtains the illuminance of the sensor 10, that is, the illuminance of the detected part when the camera 20 detects the luminance, from the input β and the first relational data in the reference image data memory 72. To the threshold correction unit 77. Further, the image of the background portion is stored in the reference image data memory 72 as a reference image, and a difference between the stored portion and the corresponding portion of the image when the color changes is calculated. Output to the unit 77.

In the threshold correction unit 77, the input illuminance and
Based on the distance L from the sensor 10 to the camera 20 (see FIG. 5A), the second relational data in the reference image data memory 72, and the above-described difference accumulation value, whether or not there has been a luminance change, A correction value of a threshold value serving as a criterion for determining whether or not the state is set is calculated. This correction is performed because the threshold value changes due to the weather, the surrounding illuminance, the emission color of the light-emitting body, and the like. The threshold value determination unit 75 corrects a preset threshold value with the input correction value, and outputs the corrected threshold value THL to the luminance comparison determination unit 80.

In the luminance comparing and judging section 80, the judgment reference value A inputted from the reference value decision section 74 and the threshold value decision section 7
Then, a comparison is made between the magnitudes of the threshold values THL input from No. 5 and a result indicating whether or not the detection of inundation is determined is output to the alarm circuit 90 (see FIG. 3). Then, as shown in FIG.
In the case of 0, when a result indicating that inundation is detected is input, an alarm signal is output to the outside, the current image is digitally output from the video switching unit 40, and the image compressed by the band compression unit 81 is converted by the modem 82. To the management center side via the public line 110 (see FIG. 2). Center system 13
Numeral 0 indicates that the transmitted data can be converted and displayed, for example, a personal computer, a computer and a VDT terminal, and the transmitted image data and an alarm signal are converted to display an image. At the same time, an alarm is sounded as necessary.

In the above example, a system for remotely monitoring inundation in a leased room using a public line has been described. However, the inundation detection sensor, the inundation detection device, and the inundation detection system according to the present invention detect inundation in a leased room. It is not limited to
It can be used for detecting inundation of any monitoring target indoors and outdoors. Also, the configurations of the waterlogging detection device and the waterlogging detection system of the present invention are not limited to the above examples. For example, in the above example, the data obtained by the camera 20 is converted and output by the A / D conversion unit 30, but some cameras internally output signals by digitizing them. May be used. In this case, A /
No D conversion unit 30 is required. In the signal processing, the color signal was used to determine the area of the changing part and the background part, and the luminance signal was used to compare the two areas. However, both of the color and the luminance could be used. It is preferable to select according to the emission color of the light emitter used for the sensor. When the luminance signal is used for the comparison determination, the camera of the image input means may be black and white, so that the cost of the apparatus can be reduced. Although the average value of the signal of each pixel in the area is used for comparison, other methods such as taking a value with a large number of pixels can be used. The same applies to the determination of the threshold value and its correction. Further, in the example of FIG. 5, two separate frames, a monitoring frame and a reference frame, are set,
Although the comparison is performed between them, for example, it is also possible to set only the monitoring frame in the processing area and perform the comparison inside and outside the monitoring frame.

Further, in the above example, when the alarm signal is output, the image captured by the camera 20 monitoring the sensor 10 is externally output and transmitted to the management center. For example, a camera capable of separately capturing the whole of the monitoring facility is installed. In addition, it is possible to use a surveillance camera properly, such as capturing an image from the camera and transmitting the image when an alarm signal is output. External transmission of information such as images is performed at least when flooding occurs, but it is of course possible to transmit and display the information. The warning by the warning signal can be performed by an arbitrary method such as a warning sound, a warning display on a monitor screen, and lighting of a warning lamp. These alarms can also be issued on the rented room side where the sensor is located so that they can be seen outside.

As described above, the inundation detection system has been described as an embodiment of the present invention. In the above-mentioned inundation detection system, a temperature abnormality detection sensor, an oxygen deficiency detection sensor, a cable fire detection sensor, etc. of the present invention are used instead of the inundation detection sensor. By using the abnormality detection sensor described above, an abnormality detection system that detects these various abnormalities can be provided.

[0026]

There is little malfunction due to ambient vibration and the like, and an excellent effect that an abnormality can be detected in a non-contact manner from a place distant from the monitoring target is exhibited. In addition, the abnormality detection device of the present invention is simple to install and can detect the response of the sensor even in a dark place. The effect of the environmental conditions described above can be eliminated and the device can be suitably operated. According to the abnormality detection system of the present invention, the occurrence of an abnormality in a monitoring place can be constantly monitored,
Since the system accurately detects abnormalities and immediately notifies a remote management center or the like, there is an excellent effect that sufficient equipment management can be efficiently performed.
