  FIG. 5 schematically shows a state when the playground equipment diagnosis system 100 of FIG. 4 is used for diagnosis of the playground equipment 5 that is a management target and a diagnosis target. FIG. 6 is an enlarged view of a portion surrounded by a broken line in FIG.

  5 and 6, the vibration generator 2 and the vibration detector 3 are attached to a belt-like fixed belt 6 for the purpose of ensuring ease of handling and measurement stability. A diagnostic belt 7 is configured. Here, when the vibration generating device 2 and the vibration detecting device 3 are closely fixed to a fixed column 51 (described later) to be diagnosed, the vibration generating device 2 and the vibration detecting device 3 attach the fixing column 51 to the fixing belt 6. The structure is adjustable so as to face each other.

  As shown in FIG. 5, the play equipment 5 to be diagnosed includes a chair 50 made of a predetermined member, a plurality of fixing columns 51 for fixing the play equipment 5 to the ground, and a beam that supports the chair 50 in a hollow state. 52, small beams 53 and 54 for preventing wobbling of the fixed column 51 and the beam 52, a fastener 55 for connecting the fixed column 51, the beam 52 and the small beam 53 and 54, and the beam 52 so that the chair 50 can swing. It is a wooden swing provided with the chain | strand 56 linked with.

  In the play equipment 5, both end portions (upper end portion 51A and lower end portion 51C) of the fixed column 51 and both end portions of the beam 52 and the small beams 53 and 54 are exposed to the outside, and the lower end 51C of the fixed column 51 is It is in contact with the ground. Further, the fastener 55 is driven into the fixed column 51, the beam 52, and the small beams 53 and 54, and a member (not shown) for fixing the chain 56 that supports the chair 50 so as to be swingable is driven into the beam 52. ing.

  Here, both ends of the fixed column 51, the beam 52 and the small beams 53 and 54, and the places where the fasteners 55 and the fixing members are driven are usually easily deteriorated due to the influence of the external environment. Due to the use of these, defects (cracks, cracks, decay, etc.) that reduce the strength of the play equipment 5 are likely to occur at these locations. In particular, since the lower end portion 51C of the fixed column 51 is in contact with the ground, it can be said that it is the most prone part of the playground equipment 5. Further, as illustrated in FIG. 7, for example, the fixed column 51 generally has a node 51D, and water easily collects in the periphery 51E of the node 51D, and the periphery 51E of the node 51D easily rots. In addition, although not shown, there is a possibility that cavities are generated everywhere in the play equipment 51 due to insect bites by termites and the like.

  As described above, in the play equipment 5, various defects that reduce the strength of the play equipment 5 may occur in various parts. In the daily inspection and diagnosis of the play equipment 5, confirmation is made by visual inspection, palpation, auscultation, and the like. It can be said that it is extremely difficult to accurately grasp the danger of the playground equipment 5 before an accident due to the playground equipment 5 occurs only by using a subjective method. Therefore, if any signs of danger are seen in the playground equipment 5, a method of immediately stopping the use of the playground equipment 5 or removing it may be considered. However, in such a case, in reality, there is no possibility of an accident due to the playground equipment 5, or there is almost no possibility that the playground equipment 5 has been stopped or removed even though there is almost no accident. Is very expensive. It is also conceivable to disassemble or scrape the members of the play equipment 5 and to inspect the depth and strength of corrosion cracks in detail using advanced precision equipment. However, in such a case, the members of the playground equipment 5 are disassembled or shaved every time the inspection is performed, so that the inspection may cause the playground equipment 5 to be defective, as well as cost and labor. There is a problem that it is not possible to carry out inspection on a daily basis due to excessive application. Moreover, there is a possibility that the play equipment 5 cannot be used for a long time every time it is inspected, and the role as the play equipment 5 cannot be sufficiently achieved.

  On the other hand, it can be said that the playground equipment diagnosis system 100 of the present embodiment can solve these problems all at once and is extremely useful. Hereinafter, the operation of the playground equipment diagnosis system 100 will be described.

  FIG. 8 shows a playground equipment diagnosis procedure in the playground equipment diagnosis system 100 of the present embodiment. In this figure, in order to make it easy to understand the exchange between the playground equipment diagnosis contractor B, the playground equipment diagnosis apparatus 4, the vibration generator 2 and the vibration detection apparatus 3 using the playground equipment diagnosis system 100, the playground equipment diagnosis contractor B and the playground equipment diagnosis apparatus 4 The flow is shown for each of the vibration generator 2 and the vibration detector 3.

  In performing the playground equipment diagnosis, the playground equipment diagnosis contractor B first installs the diagnostic belt 7 on the playground equipment 5 (step S101). For example, as shown in FIG. 2, the diagnostic belt 7 is wound around the upper end 51A, the center 51B, and the lower end 51C of the fixed column 51. At this time, the diagnostic belt 7 is wound so that the vibration generator 2 and the vibration detector 3 are firmly attached to the fixed column 51.

  Next, the playground equipment diagnosis company B requests the playground equipment diagnosis apparatus 4 to start the playground equipment diagnosis program 42A (step S101). For example, an icon displayed on the display unit 44 is clicked with the mouse. Then, the playground equipment diagnosis program 42A is activated (step S103), and information input of the playground equipment 5 is requested (step S104). For example, an input form is displayed on the display unit 44.

  Next, the playground equipment diagnosis contractor B inputs the information on the playground equipment 5 (for example, the type and material of the playground equipment 5, the installation site of the diagnostic belt 7, etc.), and requests the execution of diagnosis (step S105). For example, after filling each item in the input form displayed on the display unit 44 using a mouse or a keyboard (for example, the type of playground equipment 5, the material, the installation site of the diagnostic belt 7, etc.), the diagnosis execution button is moved with the mouse. click.

  Then, in the playground equipment diagnosis device 4, the vibration condition of the vibration generator 2 is determined based on the input information of the playground equipment 5, and a vibration generation signal corresponding to the condition is output (step S106). For example, when a swing is used as the type of the play equipment 5, cypress is used as the material, and the upper end 51A, the center 51B, and the lower end 51C of the fixed column 51 are input as the installation site of the diagnostic belt 7, the center is 1500 Hz. A vibration generation signal is generated that requests that the operation of continuously sweeping within a predetermined frequency band is sequentially performed in the order of the upper end portion 51A, the central portion 51B, and the lower end portion 51C. 2 is transmitted.

  The vibration generating signal transmitted from the playground equipment diagnosis device 4 is received by the vibration generating device 2, and the vibration transmitting unit 21 is vibrated under the vibration condition corresponding to the received vibration generating signal (step S107). For example, vibration that continuously changes within a predetermined frequency band centered on 1500 Hz occurs in the order of the upper end 51A, the center 51B, and the lower end 51C.

  The vibration in the vibration transmitting unit 21 propagates through the fixed column 51 and is detected by the respective vibration detection units 33 installed at the upper end portion 51A, the central portion 51B, and the lower end portion 51C of the fixed column 51. An electrical signal corresponding to the direction and magnitude of vibration at the portion where the unit 33 is disposed is output from the vibration detection device 3 (step S108).

  At this time, if there is a defect that reduces the strength of the playground equipment 5 in the propagation path inside the fixed column 51, the vibration detector 33 detects vibrations having a frequency distribution different from the case where there is no such defect. Is done. In addition, the vibration detection unit 33 may output from the vibration detection unit 3 a signal obtained by performing some signal processing on the electrical signal by the signal processing unit 32.

  The electrical signal transmitted from the vibration detection device 3 is received by the playground equipment diagnostic device 4, and frequency analysis (for example, wavelet transform) is performed on the received electrical signal to derive measurement data (step S109). . Thereafter, the obtained measurement data is compared with reference data 42B prepared in advance, the state of the fixed column 51 is diagnosed, and the diagnosis result is output to the display unit 44 (step S110).

  For example, the measurement data obtained when frequency analysis is performed on the electrical signal obtained by the vibration detection unit 33 of the lower end 51C when the vibration transmission unit 21 of the lower end 51C is vibrated greatly from the reference data. On the other hand, if the other measurement data is substantially the same as the reference data, and the amount of the deviation does not exceed a predetermined threshold value, some defect has occurred in the lower end portion 51C of the fixed column 51. However, the playground equipment diagnosis device 4 determines that the defect is not sufficient to replace the fixed column 51, and some defect has occurred in the lower end portion 51C of the fixed column 51. However, the replacement of the fixed column 51 is unnecessary at present. Is displayed on the display unit 44. Conversely, when the amount of deviation exceeds a predetermined threshold, the playground equipment diagnosis device 4 determines that a serious defect has occurred in the lower end portion 51C of the fixed column 51 and the fixed column 51 needs to be replaced. Then, a diagnosis result indicating that the fixed column 51 needs to be replaced due to a serious defect occurring in the lower end portion 51C of the fixed column 51 is displayed on the display unit 44.

  Further, for example, measurement data obtained when frequency analysis is performed on the electrical signal obtained by the vibration detection unit 33 of the lower end 51C when the vibration transmission unit 21 of the lower end 51C is vibrated is the reference data. When other measurement data is almost the same as the reference data, when the measurement data is normalized with the reference data, and the normalized measurement data does not exceed the predetermined threshold The playground equipment diagnosis device 4 determines that the lower end 51C of the fixed column 51 is not defective enough to replace the fixed column 51, but some defect occurs in the lower end 51C of the fixed column 51. However, a diagnosis result indicating that the replacement of the fixed column 51 is not necessary at present is displayed on the display unit 44. Conversely, when the measurement data after normalization exceeds a predetermined threshold value, a serious defect has occurred in the lower end portion 51C of the fixed column 51, and it is necessary to replace the fixed column 51. The diagnosis result determined by the device 4 and indicating that the fixed column 51 needs to be replaced due to a serious defect occurring at the lower end 51C of the fixed column 51 is displayed on the display unit 44.

  As described above, in the playground equipment diagnosis system 100, the frequency analysis is performed on the electrical signal corresponding to the vibration of the predetermined portion (fixed column 51) of the playground equipment 5 output from the vibration detection device 3, and thus obtained. The state of the predetermined part (fixed column 51) of the playground equipment 5 is diagnosed by comparing the measurement data with the reference data 42B prepared in advance. That is, in this embodiment, it is not necessary to disassemble or scrape the members of the playground equipment 5, and it is not necessary to use sophisticated precision equipment. In addition, anyone can easily test without requiring subjective judgment. Thereby, daily safety evaluation of playground equipment can be performed quantitatively and objectively.

  Next, operations of the playground equipment management device 1 and the terminal device 4 according to the present embodiment will be described with reference to FIGS. 9 to 12. For convenience of explanation, (A) a procedure for registering the playground equipment 5 as a fixed asset and (B) a procedure for managing the playground equipment 5 will be described separately.
