Description

Description Building management system and method

The present invention constantly monitors the quality change of a building and can promptly respond to the detected quality abnormality. In addition, the same system can be used to change the environment due to an intruder into a building such as a house. Monitoring and monitoring of building management systems and methods. Background art

Conventionally, for quality inspection of buildings such as houses, bridges, and tunnels, since the buildings are used after inspections, inspections are performed without destroying the inspection target and without causing changes that would hinder use. So-called non-destructive inspection is adopted.

Therefore, surface defects such as cracks and scratches are generally detected by manual inspection or by image analysis inspection of continuous scanning images taken while traveling on an inspection vehicle in the tunnel. Internal defects are detected by hammering inspection with a hammer or ultrasonic inspection using ultrasonic waves. These inspections are regularly performed, and based on the inspection data, the degree of damage to the building is determined, a repair plan is established, and the quality of the building is managed.

However, in such a quality management system, if a serious defect occurs, it will be left without any measures until the next inspection, and the defect will spread during that time, leading to the collapse of the entire building There was fear.

In addition, the above-mentioned quality inspections and their analysis require a high degree of specialty, especially in the case of residential houses, the owner needs to make a repair plan after contacting the analysis results from an inspection specialist, Response was difficult.

In addition, since it is necessary to change the inspection method according to the type and location of the defect, it is necessary to perform multiple types of inspections to increase the accuracy of determining the degree of damage and the damage position, which increases the cost of inspection. Problem. Here, the ultrasonic inspection is an application of the Doppler effect of ultrasonic waves. That is, a measuring wave is transmitted into the member to be measured from a transmitting point provided at the same position as the measuring point, and the time for the measuring wave to reciprocate in the member to be measured is measured. If there is a defect, the measuring wave hitting the defect will be reflected and return to the measuring point in a short time, but this return time and the return time of the measuring wave reflected and returned from the end of the member to be measured will be The time difference is determined, and the time difference is analyzed to determine the type, position, size, etc. of the defect.

However, in the Doppler effect method, since the reflected wave is measured, depending on the type, position, and size of the defect, the sound wave may be scattered or transmitted without being reflected, and the defect may not be detected. However, there was a problem that the accuracy of defect detection was significantly reduced. In addition, since the accuracy of defect detection largely depends on the homogeneity of the members, it is applicable if the member to be measured is a homogeneous material such as concrete or metal material. It is difficult to apply to materials such as glued lumber where the material varies greatly at the position. As a result, there has been a problem that the inspection of the wood and the glued laminated wood for defects must rely on the experience and intuition of an inspection specialist, and the inspection accuracy is low. In addition, the deterioration of wood and glulam quality is not due to defects such as scratches, but to water leakage in the material due to long-term use, increased water content in the material due to water leakage, and propagation of bacteria by the water. However, there is a problem that it is not possible to accurately detect the wetted portion and the corroded portion despite the large influence of the corrosion caused by the corrosion.

On the other hand, the presence of an intruder in a building such as a house has been detected in the main monitoring locations such as entrances and exits of buildings, windows and other high-level rooms such as document rooms. Sensors such as infrared sensors and acoustic sensors and surveillance cameras were installed to check for intrusion at the main monitoring position.

However, if an intruder enters from an entrance other than the main monitoring position, or if the intruder acts outside the detection range of the sensing sensors or in the blind spot of the surveillance camera, the presence of the intruder cannot be detected at all. was there. Therefore, in order to reliably detect an intruder, it is necessary to provide a large number of sensing sensors and surveillance cameras, and there has been a problem in that the cost of equipment and installation is high.

The present invention will be described in more detail with reference to the accompanying drawings. First, an overall configuration of a building management system according to the present invention will be described with reference to FIGS.

In this embodiment, a description is given mainly of a wooden house made of ordinary wood, glued laminated lumber made by bonding a large number of sawn boards or timbers with an adhesive, but concrete houses and high-rise It can be applied to large buildings such as buildings, roads, bridges, and tunnels. By applying the system and method according to the present invention, the quality of various buildings and changes in the environment are constantly monitored and prompt responses can be made. Quality degradation and intruders Damage can be kept to a minimum.

As shown in FIGS. 1 to 4, in a building management system 1, a plurality of sound wave transmitting / receiving devices 2 are provided in a wooden house 11, and a sound wave transmitting / receiving device 3 constituting the sound wave receiving / transmitting device 2 and The sound wave receiving device 4 is attached to both ends of a member to be measured 12 composed of a main structural member including a column 12a and a horizontal member 12 such as a base, a girder, or a beam.

In the present embodiment, the sound wave transmitting device 3 and the sound wave receiving device 4 are integrated into a single sound wave receiving / transmitting device 2 so that the transmitting function and the receiving function can be switched as required. As a result, the number of measurement points required for transmitting and receiving sound waves can be reduced, and the number of wirings extending from the sound wave transmitting / receiving device 2 can be reduced, and troubles such as costs and disconnection of wiring work occur. Can be suppressed. Of course, the sound wave transmitting device 3 and the sound wave receiving device 4 may be arranged separately.

Such a sound wave transmitting / receiving device 2 is connected to a sound wave control device 5, and the sound wave control device 5 controls the waveform and frequency of a transmitted sound wave output from the sound wave transmitting device 3 into the member 12 to be measured. It is possible to control sound wave characteristics, display waveform data of transmitted sound waves (hereinafter referred to as “result data”), and transmit the result data to a network 6 such as the Internet by an output device. The performance data also includes waveform data of a received sound wave input from the measured member 12 to the sound wave receiving device 4 and a difference data obtained by quantifying a difference between the received sound wave and the transmitted sound wave.

Here, a sound wave used in the present invention and a measuring method thereof will be described. Note that the sound wave to be used is preferably an inaudible sound having a frequency of 20 KHz or more, since the sound wave exhibits remarkable directivity as compared with the audible sound, but is not particularly limited. The attenuation method is applied as the sound wave measurement method. With the attenuation method, a transmitting point is provided on one side of the member to be measured and a measuring point is provided on the other side, and the measurement wave is propagated through the member to be measured, and the transmitted ultrasonic wave output from the transmitting point and the transmission to the measuring point It detects the difference from the input received ultrasonic wave. If there is a change in the quality of the member to be measured, the attenuation rate fluctuates. For example, as shown in Fig. 5, at the quality change position 55 where corrosion and water wetting occur, the attenuation curve 15 of the corroded material has a lower sound pressure and greater attenuation than the attenuation curve 13 of the normal material. Conversely, the damping curve of water-wet material 14 has a lower sound pressure than that of normal material. High and low attenuation. In other words, actual data on the attenuation of abnormal materials such as corrosive materials and wet materials (hereinafter referred to as “standard data”) is accumulated, and compared with the actual data of the member to be measured. It is possible to detect that there is an abnormal part in the measuring member, and to further estimate the cause of the occurrence.

Unlike the Doppler effect method, this attenuation method uses not a reflected wave but a transmitted wave propagating from one side to the other of the member to be measured, so that a variety of defects can be detected. In addition to such normal defects that exist locally, it is also possible to reliably detect the effects of moisture, corrosion, and the like that are widely distributed throughout the member to be measured. In addition, the attenuation method observes a simple change in the attenuation of the measurement wave propagating in one direction, so even if the material varies in position such as wood or glued laminated wood, the attenuation change of the measurement wave due to defects, moisture, etc. Is remarkable, so that the defect, moisture, and the like can be detected with good quality.

That is, in a building management system 1 that collects and analyzes management information on a quality change of a building, a sound wave transmitting device 3 and a sound wave receiving device 4 are provided with a main measured member 12 of the building interposed therebetween, A sound wave controller 5 that can quantify the difference between the detected transmitted sound wave and the received sound wave is provided, so that the attenuation method can be applied to the collection and analysis of management information. A wide variety of quality changes in buildings, such as increases and erosion, can be detected with a single system, and inspection costs can be reduced. In particular, it can be detected with high accuracy even in wooden houses made of heterogeneous wood and laminated wood.

Further, in the building management system 1 that collects and analyzes management information on the quality change of the building, in the building management system 1, the sound wave is a propagation means for transmitting the sound wave between both ends of the main member 12 to be measured in the building 1. A transmitting device 3, a sound wave receiving device 4, a sound wave control device 5 which is a control means for controlling propagation of sound waves, and an output device which is an output means for transmitting actual data of transmitted sound waves and received sound waves to a network such as the Internet. , The attenuation method can be applied to the collection and analysis of building management information, and it is possible to detect the occurrence of defects, increase in moisture, erosion and other quality changes, and to network the management information. The management information can be shared via a network and the range of use can be expanded. Now, the sonic wave control device 5 is connected to a network 6, and the network 6 includes a portable terminal 8 such as a mobile phone or a personal computer 8 of a user 7 using the wooden house 11, The management information analyzer 10 of the information management center 9 that provides a building management service is connected.

The management information analyzer 10 is capable of analyzing the standard data obtained from the deteriorated members, for example, defects such as cracks and nests, increased moisture due to rain leaks, and abnormal members that have been corroded by propagation of bacteria. It can be compared with the actual data of the material to be measured, and the data of the analysis result, the probable cause and the countermeasure plan (hereinafter referred to as “analysis data”) can be output. The terminal 8 is configured to be able to freely display management information such as analysis data.

That is, as described above, in the building management system 1 that collects and analyzes the management information on the quality change of the building, the building includes a plurality of sound wave transmitting devices 3 and a sound wave receiving device with the member to be measured 12 interposed therebetween. The sound wave transmitting device 3 and the sound wave receiving device 4 are provided with a sound wave control device 5 for controlling sound wave reception and transmission, and a management information analysis device 10 of an information management center 9 and a user of the management information. 7 and connected to the terminal 8, and in the storage device, the actual data of the transmitted sound wave and the received sound wave of the member to be measured, and the transmitted sound wave and the received sound wave of the abnormal member whose quality has deteriorated due to the occurrence of a defect or wetness of water. And the analysis data obtained from the standard data and the performance data are stored, and management information such as the analysis data and performance data can be displayed on the terminal. With the sound wave transmitting device 3 and the sound wave receiving device 4, changes in the quality of the building can be constantly or frequently monitored, and the user 7 can check the actual data output from the sound wave control device 5, The analysis data output from the information analyzer 10 can be accessed overnight from the terminal 8, so even if a serious defect occurs, it can be repaired quickly to prevent the building from tilting or collapsing. be able to. In addition, the user 7 can directly access the analysis data that is easy to understand without any specialized knowledge, and independent and promptly without waiting for the communication of the analysis results from the inspection specialist as in the past. You can make a repair plan.

Further, in a building management system that collects and analyzes management information on a quality change of the building, the building includes a plurality of sound wave transmitting devices 3 with a member to be measured 12 interposed therebetween. A sound wave receiving device 4 is provided, and the sound wave transmitting device 3 and the sound wave receiving device 4 are connected to a network 6 such as the Internet via a sound wave control device 5 for controlling transmission and reception of sound waves. The management information analysis device 10 of the information management center 9 is connected to the terminal 8 of the user 7 of the management information. Data, standard data obtained from transmitted sound waves and received sound waves of abnormal members whose quality has deteriorated due to defects or wetness, etc., and analysis data obtained from the standard data and the actual data are stored. Since the management information such as the analysis data and the performance data can be displayed on the terminal 8, the management information such as the analysis data and the performance data can be exchanged on the network 6, and can be exchanged with the user 7. It is also possible to share management information between multiple users 7 in addition to the information management center 9 and more quickly and accurately respond to changes in building quality and the environment. It becomes.

If necessary, the management information analyzer 10 may be a related company such as a construction company that built the building, a loan company that the user 7 borrowed the construction cost, or a guarantee company that contracted a guarantee for the building. It is also possible to connect the company terminal 3 2 such as a personal computer 3 via the network 6 or the dedicated line 3 3, whereby management information can be quickly transmitted to the related company 3 1, The relationship between the related companies 3 1 and the users 7 will be closer, and a repair plan can be made accurately and promptly.

Further, as the ultrasonic wave used for the wooden house 11 made of materials such as inhomogeneous wood and laminated wood, a phase-inverted composite ultrasonic wave having a stable attenuation rate is preferable.

The phase-inverted composite ultrasonic wave is a synthetic ultrasonic wave obtained by superimposing a phase-inverted ultrasonic wave whose phase is inverted with the ultrasonic wave on a sine wave. For example, superimposing a 90 KHz sine wave and a 60 KHz antisine wave can produce 90 KHz, 60 KHz, and 30 KHz composite ultrasonic waves. In other words, a special ultrasonic wave can be synthesized by changing the output of the original ultrasonic wave.

The half-phase wave generated in the synthetic ultrasonic wave has a very small energy loss while in the synthetic ultrasonic wave, and propagates stably to the defect position with almost no attenuation. Then, when reaching the defect, the synthesized ultrasonic wave is scattered, so that after the defect position, the above-mentioned half-phase wave must propagate only by its own energy, and gradually becomes Decays. That is, since the attenuation change of the ultrasonic wave at the defect position is large, the position of the defect can be detected more accurately from the attenuation change position.

In other words, in a wooden house 11 made of wood, laminated wood, etc., applying the attenuation method makes it possible to detect the occurrence of defects, increase in moisture, erosion and other quality changes, and furthermore, the attenuation rate is stable. By applying the phase-inverted composite ultrasonic wave, the detection accuracy can be further improved.

The terminal 8 has a built-in executable browser, which is a program for searching for a server, so that the user 7 can freely access the management service home page from the terminal 8.

In such a configuration, the result data transmitted from the sound wave controller 5 to the management information analyzer 10 is stored in the result database 20a, and the result data 20a is set to the standard The actual data and the standard data are read from the database 20b, respectively, and the actual model data and the standard data are read from the analytical model data read from the evening base 20d into the main memory 19 with respect to the actual data and the standard data. Based on the data program, the central processing unit 18 performs detailed analysis of the actual data. The result is stored in the analysis database 20c as analysis data. As a result of this detailed analysis, when it is determined that the building is in an abnormal state, the address of the corresponding terminal 8 is determined from the destination address database 20e based on the user information sent together with the actual data. Investigation, and automatically transmits analysis data such as the probable cause to the terminal 8.

If it is determined that the building is in an abnormal state, the analysis data is used by the user of the management information. Since the information is automatically transmitted to the terminal 8 of 7, the user 7 does not need to frequently access the homepage for the management service, which can reduce the labor and time required for the user 7 for building management, and furthermore, the user 7 The occurrence of abnormalities can be known with almost no time lag, and prompt responses can be made. The sound wave control device 5 is also provided with a storage device (not shown). Like the management information analysis device 10, standard data, analysis model data, and transmission destination address data are accumulated on a data base. The configuration is such that it is possible to determine whether or not the performance data from the sound wave transmitting / receiving device 2 may be abnormal. Therefore, only when it is judged that there is a possibility of abnormality, the management information analyzer 1 is automatically extracted from the destination address database. You can check the address of 0 and send the result data overnight.

At this time, the result data may be transmitted to the management information analysis device 10 of the information management center 9 and simultaneously to the terminal 8 of the user 7. As a result, the user 7 can know the occurrence of the abnormality without waiting for the detailed analysis by the management information analyzer 10, and can take a quicker response.

Further, the sound wave control device 5 automatically transmits all the result data from the sound wave transmitting / receiving device 2 to the management information analysis device 10 without judging whether or not there is a possibility of abnormality. The determination of the possibility of abnormality and the detailed analysis may be performed. As a result, the processing load on the management information analyzer 10 increases, but it is not necessary to provide a large-scale storage device 20 in the sound wave controller 5.

Conversely, the sound wave control device 5 may be configured to enable not only determination of the possibility of abnormality but also detailed analysis. In this case, the processing load on the management information analysis device 10 can be reduced, and the building management service can be operated with a simple device.

That is, since the storage device 20 is provided in at least one of the sound wave control device 5 and the management information analysis device 10, if there are few target buildings, the sound wave control device 5 determines whether there is a possibility of abnormality. In this way, the processing load of the detailed analysis is distributed, and when the number of target buildings increases, the possibility of abnormalities is also centrally processed by the management information analyzer 10 together with the detailed analysis, reducing the equipment cost of the acoustic wave control device 5. If the user 7 wants reliable quality control even if the service price is high, detailed analysis can be performed by both the sound wave controller 5 and the management information analyzer 10 and the scale and form of management This makes it possible to operate the system appropriately.

Next, a procedure for registering user information and analyzing management information when using the building management system 1 having the above configuration will be described with reference to FIGS. 7 to 11. FIG.

First, as shown in FIGS. 7 and 9, the user 7 performs a user registration process 41 from the terminal 8. In the user registration process 41, when the user 7 accesses the server such as the management information analyzer 10 connected to the network 6 using the terminal 8 (step 42), the HTML document Is read (step 43), and the main screen of the management service home page is displayed on the display such as the liquid crystal display of the mobile phone of the terminal 8. Is shown. Then, when an application button (not shown), which is an image for displaying a hyperlink, is selected, the display jumps from the main screen to the management application screen 22 (step 44). The management application screen 22 includes a user information input section 23 for inputting user information such as name, address, telephone number, and e-mail, and a return button for displaying a hyperlink image. Various buttons such as 24, advance button 25, and transmission button 26 are arranged. By selecting return button 24 or advance button 25, it is possible to jump to another screen freely. Then, the user information is input to the user information input section 23 (step 45), and when the input is completed, the transmission button 26 is selected to transmit the user information (step 46). Then, the user information is written and stored in the destination address database 20 e in the storage device 20 via the network 6 (step 47).

Then, as shown in FIGS. 8, 10, and 11, when a quality abnormality is detected in the wooden house 11, a management information analysis process 48 is performed. In the management information analysis processing 48, the sound wave control device 5 judges whether there is a possibility of abnormal quality (step 49), and when it is judged that there is a possibility, accesses the management information analysis device 10. (Step 50), and the result data is transmitted to the management information analyzer 10 (Step 51). When the result data is transmitted, the result data screen 27 is started up, and abnormal result data is displayed on the data display section 28 thereof. As described above, the management information analyzer 10 performs detailed analysis of the actual results (step 52), extracts the address of the terminal 8 of the user 7 (step 53), and analyzes the data to the terminal 8 as described above. The automatic transmission (step 54) is performed in order. A quality judgment screen 29 is displayed on the terminal 8, the estimated cause of the occurrence of an abnormality is posted on a judgment display section 30 in the quality judgment screen 29, and the user 7 is notified of the quality abnormality in the building. The occurrence and the probable cause of the occurrence can be immediately known.

It should be noted that the quality measurement of the member to be measured is not always performed, but a signal for starting the measurement (hereinafter, referred to as a “measurement signal”) is periodically transmitted from the management information analyzer 10 or the like to the sound wave controller 5 or the like. Alternatively, a timer is provided in the sound wave control device 5, and the sound wave transmitting device 3 and the sound wave receiving device are provided. The device 4 may be operated periodically. As a result, it is possible to prevent problems such as shortening of the life of the measuring device due to complicated measurement and inability to secure required power for a long time.

Further, a signal (hereinafter, “data calling signal”) requesting transmission of the actual data and the analysis data to the acoustic wave control device 5 and the management information analyzer 10 may be transmitted. When the overnight call signal is transmitted, the sound wave control device 5 and the management information analysis device 10 receive the signal, and based on the transmission information sent together with the overnight call signal, The analysis data is extracted from the analysis database 20c in the storage device 20, and the source address is extracted from the destination address database 20e, and the analysis data corresponding to the source is automatically transmitted. You do it. This allows the user 7 and the information management center 9 to access the analysis data as needed, and the user 7 can review the analysis data to select a repair plan, However, it is possible to estimate the repair cost by examining the applicable analysis data, and to present the estimate to the user 7.

In other words, in a building management system 1 that collects and analyzes management information on changes in the quality of a building, a plurality of sound wave transmitting devices 3 and a plurality of sound wave receiving devices 4 that sandwich a member to be measured in the building transmit outgoing sound waves. And the result data of the received sound wave, and the result data is compared with the standard data in the storage device 20 to analyze the quality state of the building, and the obtained analysis data is stored in the storage device 20. When the data call signal is transmitted after the data is stored in the management information analysis device 10, the analysis data is automatically transmitted to the terminal 8 of the management information user 7 or the management information analysis device 10 of the information management center 9. And the information management center 9 can access the analysis data as needed at any time, so that the analysis data can be shared and the range of use can be expanded.

In particular, when the data call signal is transmitted from the terminal 8 of the management information user 7, the analysis data can be freely obtained from the management information analyzer 10 of the user 7 information management center 9, and the repair plan Can be accurately determined.

When the data calling signal is transmitted from the management information analyzer 10 of the information management center 9, the information management center 9 can freely obtain the analysis data from the terminal 8 of the user 7, and the user 7 Can provide various services.
