Hereinafter, the structure and installation method of the sensor unit 10 which is a constituent device of the monitoring system 1 will be described. FIG. 5 shows an enlarged perspective view of a single sensor unit 11 included in the sensor unit 10 shown in FIG. Although the sensor unit 11 will be described as an example, the basic structure is the same for the sensor units other than the sensor unit 11.

The sensor unit 11 has an appearance in which an antenna 91 for data transmission is attached to the case 90. A built-in sensor 92, an electronic board 93, a dry battery 94, and a magnet 95 are built in the case 90.

FIG. 7 is a perspective view showing a state in which the sensor unit 11 is installed on the cylinder 66. Since the contact area between the cylinder 66 and the case 90 of the sensor unit 11 is small, the sensor unit 11 is fixed to the cylinder 66 by a binding band 61 in FIG. 7. Compared with the case of fixing with only the magnet 95, the tightening work of the binding band 61 is required, but the binding band 61 is sufficient as the additional member, and the attachment is still easy, and the sensor unit 11 is mounted on the cylinder 66. Can be fixed in any position of.

As the installation method of the sensor unit 11, the installation by the magnet 95 and the installation by the binding band 61 have been described, but the installation is not limited to these. For example, the double-sided tape 63 (see FIG. 1) may be attached and installed, or the tape may be simply placed on a table or a shelf without using additional members for installation. When placed on a table or shelf, the sensor unit 11 can be stored in the storage box 64 (see FIG. 1) for stable installation. Further, the binding band 61 and the double-sided tape 63 can also be used for fixing the external sensor 50 (see FIG. 1).

The method of installing the sensor unit has been described above, but in the present embodiment, when the magnet 95 built in the sensor unit is used or when the sensor unit is directly placed, no additional mounting member or instrument is required. be. Further, even when a member for attachment is added, a binding band 61, a double-sided tape 63, a storage box 64, etc., which are inexpensive and easy to work and install, are adopted.

Further, all of the above-mentioned sensor unit installation methods are highly versatile, and even when the sensor units are installed in a large number of places, the above-mentioned installation method can be appropriately selected according to the installation position. , It is also possible to install all of the sensor units without difficulty.

That is, the installation method of the sensor unit according to the present embodiment is an inexpensive, easy-to-work, and highly versatile installation method, and it is possible to realize an inexpensive introduction of the monitoring system 1.
