Note that where explanations are repeated, they may be omitted as appropriate. Also, in the drawings, the same or equivalent parts are given the same reference symbols, and explanations will not be repeated.

[0011] [Embodiment 1] A first embodiment of the present invention will be described below with reference to Fig. 1 to Fig. 13. First, a communication device 1 of the present embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing a telemetry system SYS including a communication device 1 of the present embodiment.

[0012] As shown in FIG. 1, the telemeter system SYS includes a communication device 1, a meter 2, a center device 3, and a center-side network control device 4. For example, the telemeter system SYS may include a plurality of communication devices 1, a plurality of meters 2, the center device 3, and the center-side network control device 4. The telemeter system SYS collects information indicating the measurement results of the meter 2. The measurement results of the meter 2 indicate the measurement values ​​measured by the meter 2. The meter 2 is an example of a "measurement device."

[0013] The meter 2 is a measuring device relating to resources or energy. The measurement target of the meter 2 is, for example, gas, water, or electricity. The meter 2 is installed for each consumer, such as, for example, a private home, a company, or various facilities. That is, the meter 2 measures, for example, the amount of gas, water, or electricity used, and outputs a measurement value as the measurement result. Below, an example will be described in which the meter 2 is a gas meter that measures the amount of gas used.

[0014] Meter 2 (gas meter) is installed in the gas pipe PG (see FIG. 3). Gas that is the object of measurement by meter 2 (gas meter) flows through the gas pipe PG. Note that the object of measurement by meter 2 (gas meter) may be LP gas (liquefied petroleum gas) or city gas. Meter 2 (gas meter) measures the amount of gas used by measuring the flow rate of gas flowing through the gas pipe PG.

[0015] The communication device 1 transmits information indicating the measurement result of the meter 2. In this embodiment, the communication device 1 transmits information indicating the measurement result of the meter 2 to the center-side network control device 4. The communication device 1 is installed for each meter 2. The communication device 1 is installed, for example, in a gas pipe PG. Alternatively, the communication device 1 is installed on a wall surrounding the meter 2.

[0016] The communication device 1 may transmit information indicating the measurement result of the meter 2 to the center-side network control device 4 via the parent device. The communication device 1 communicates with the parent device by, for example, a specific low-power radio (special low-power radio).

[0017] The communication device 1 is connected to the meter 2 so as to be able to communicate with the meter 2. In this embodiment, the communication device 1 is wired connected to the meter 2 by an electric wire PL. The electric wire PL includes a signal line and a ground line. The communication device 1 may be wirelessly connected to the meter 2. In other words, the communication device 1 may perform wireless communication with the meter 2.

[0018] The communication device 1 performs wireless communication with a center-side network control device 4. For example, the communication device 1 and the center-side network control device 4 may be connected to a wide-area wireless network Ne such as a PHS (Personal Handy-phone System) network, a FOMA (Freedom Of Mobile Multimedia Access) network, an LTE (Long Term Evolution) network, a 4G (4th generation mobile communication system) network, or a 5G (5th generation mobile communication system) network, and may perform wireless communication with each other via the wide-area wireless network Ne. Note that the communication device 1 and the center-side network control device 4 may be connected by wire.

[0019] The center device 3 is connected to the wide area wireless network Ne via a center side network control device 4. The center side network control device 4 controls communication between the communication device 1 and the center device 3 via the wide area wireless network Ne. The center device 3 collects information indicating the measurement results of the meter 2. Hereinafter, the information indicating the measurement results of the meter 2 may be referred to as the "measurement results."

[0020] Specifically, when the communication device 1 transmits the measurement result to the center-side network control device 4 via the wide area wireless network Ne, the center-side network control device 4 transmits the measurement result received from the communication device 1 to the center device 3. The center device 3 stores the measurement result received from the center-side network control device 4 for each meter 2. In other words, the center device 3 stores the measurement result for each consumer. The center device 3 includes, for example, a database server.

[0021] Next, the communication device 1 of the present embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the configuration of the communication device 1 of the present embodiment.

The processor of the control unit 91 controls each element of the communication device 1 by executing various computer programs stored in the storage device of the storage unit 92.

[0024] The operation unit 94 receives instructions for the communication device 1. The operation unit 94 includes, for example, a dip switch and a push switch. The dip switch receives, for example, an instruction to switch the operation mode of the communication device 1. The push switch causes the control unit 91 to execute the instruction received by the dip switch.

[0025] The notification unit 93 notifies various information related to the communication device 1. The notification unit 93 notifies various information to a worker performing installation or maintenance work on the communication device 1. For example, the notification unit 93 notifies the field strength of radio waves received by the communication device 1. Alternatively, the notification unit 93 may notify the field strength of radio waves transmitted by the communication device 1. The notification unit 93 includes, for example, an LED (Light Emitting Diode) or an LCD (Liquid Crystal Display).

[0026] The wireless communication unit 95 is connected to the wide area wireless network Ne and performs wireless communication via the wide area wireless network Ne. The wireless communication unit 95 includes, for example, a wireless communication module that complies with the communication protocol of the wide area wireless network Ne. The wireless communication unit 95 performs communication with the center side network control device 4 by transmitting and receiving radio waves via an antenna (not shown).

[0027] The connection unit 96 has at least one port. An electric wire PL is connected to the connection unit 96. The connection unit 96 is wiredly connected to the meter 2 via the electric wire PL. The control unit 91 acquires the measurement result from the meter 2 via the connection unit 96. The control unit 91 controls the wireless communication unit 95 to transmit the measurement result to the center-side network control device 4. As a result, the wireless communication unit 95 transmits the measurement result to the center-side network control device 4.

[0028] Next, the communication device 1 of this embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing the communication device 1 of this embodiment. More specifically, Fig. 3 shows the communication device 1 disposed in a gas pipe PG.

[0029] In this specification, the front-rear direction, the left-right direction, and the up-down direction are defined for ease of understanding. In this embodiment, the side where the front cover 113 (see FIG. 4) is arranged is the front side (front side) of the communication device 1, and the opposite side is the rear side (rear side) of the communication device 1. Also, the side where the upper attachment part 131 (see FIG. 4) is arranged is the upper side of the communication device 1, and the side where the lower attachment part 132 (see FIG. 4) is arranged is the lower side of the communication device 1. Alternatively, when the communication device 1 is viewed from the front side, the side where the front cover 113 (see FIG. 4) is arranged is the lower side of the communication device 1, and the opposite side is the upper side of the communication device 1. Also, the side where the left attachment part 141 (see FIG. 6) is arranged is the left side of the communication device 1, and the side where the right attachment part 142 (see FIG. 6) is arranged is the right side of the communication device 1. Alternatively, the right side when the communication device 1 is viewed from the front side is the left side of the communication device 1, and the opposite side is the right side of the communication device 1. However, the front-rear, left-right, and up-down directions are defined merely for the convenience of explanation, and the definitions of these directions are not intended to limit the orientation of the communication device of the present invention when used or assembled.

[0030] As shown in Fig. 3, the housing 11 can be disposed in a pipe for supplying resources or energy. The pipe for supplying resources is, for example, a gas pipe PG or a water pipe. The pipe for supplying energy is, for example, a gas pipe PG or an electric conduit. An electric conduit is a pipe in which electric wires for supplying power are disposed. The housing 11 is made of, for example, a synthetic resin.

[0031] In this embodiment, the housing 11 is disposed in the gas pipe PG. More specifically, the housing 11 is disposed in the L-shaped portion PGL of the gas pipe PG. The L-shaped portion PGL is a portion of the gas pipe PG that is bent in an L shape. In other words, the L-shaped portion PGL is a portion of the gas pipe PG that is bent at a right angle.

[0032] The L-shaped portion PGL has a vertical pipe PG1, a horizontal pipe PG2, and a bent portion PG3. The vertical pipe PG1 extends in the vertical direction. The horizontal pipe PG2 extends in the horizontal direction. The bent portion PG3 bends from the vertical direction to the horizontal direction. Alternatively, the bent portion PG3 bends from the horizontal direction to the vertical direction. The vertical direction is approximately parallel to the vertical direction. The horizontal direction is approximately parallel to the horizontal direction. The vertical pipe PG1 is an example of a "first pipe." The horizontal pipe PG2 is an example of a "second pipe."

[0033] One end of the vertical pipe PG1 is connected to one end of the bent portion PG3. One end of the horizontal pipe PG2 is connected to the other end of the bent portion PG3. The vertical pipe PG1 extends vertically from one end of the bent portion PG3. The horizontal pipe PG2 extends horizontally from the other end of the bent portion PG3. In the example shown in FIG. 3, one end of the bent portion PG3 faces downward, and the vertical pipe PG1 extends downward (first direction) from the bent portion PG3. In addition, the other end of the bent portion PG3 faces left, and the horizontal pipe PG2 extends leftward (second direction) from the bent portion PG3.

[0034] 3, the communication device 1 further includes a bundling member 12. The bundling member 12 bundling the housing 11 to a pipe for supplying resources or energy. In this embodiment, the bundling member 12 bundling the housing 11 to the L-shaped portion PGL of the gas pipe PG. The bundling member 12 is, for example, a cable tie.

[0035] In detail, the bundling member 12 includes a first bundling member 121 and a second bundling member 122. The first bundling member 121 bundling the housing 11 to the vertical pipe PG1. The second bundling member 122 bundling the housing 11 to the horizontal pipe PG2. Therefore, the housing 11 is attached to the vertical pipe PG1 and the horizontal pipe PG2 by the first bundling member 121 and the second bundling member 122. As a result, the housing 11 is attached to the L-shaped portion PGL of the gas pipe PG. By attaching the housing 11 to the L-shaped portion PGL of the gas pipe PG, the communication device 1 can be attached to the gas pipe PG in an upright position. Here, the upright position indicates that the top and bottom of the communication device 1 are aligned vertically.

[0036] Next, the communication device 1 of the present embodiment will be described with reference to Figs. 4 to 13. Fig. 4 is a front view of the communication device 1 of the present embodiment. Fig. 5 is a right side view of the communication device 1 of the present embodiment. Fig. 6 is a rear view of the communication device 1 of the present embodiment. Fig. 7 is a top view of the communication device 1 of the present embodiment. Fig. 8 is a bottom view of the communication device 1 of the present embodiment.

[0037] 4, the housing 11 has a housing main body 111, a first attachment portion 13, and a second attachment portion 14. The housing main body 111 has, for example, a substantially rectangular shape when viewed from the front. The first attachment portion 13 and the second attachment portion 14 are coupled to the housing main body 111.

[0038] The first mounting portion 13 is attached to the vertical pipe PG1 described with reference to Fig. 3. The second mounting portion 14 is attached to the horizontal pipe PG2 described with reference to Fig. 3. The first mounting portion 13 and the second mounting portion 14 are disposed at positions where the second mounting portion 14 contacts the horizontal pipe PG2 when the first mounting portion 13 contacts the vertical pipe PG1. The first bundling member 121 described with reference to Fig. 3 bundles the first mounting portion 13 to the vertical pipe PG1. The second bundling member 122 described with reference to Fig. 3 bundles the second mounting portion 14 to the horizontal pipe PG2.

[0039] Next, the communication device 1 of the present embodiment will be further described with reference to Fig. 4 and Fig. 5. As shown in Fig. 4 and Fig. 5, the housing main body 111 has a main body part 112 and a front cover 113. The front cover 113 is detachable from the main body part 112.

[0040] Main body 112 is a hollow box-shaped member that houses electronic components such as a communication circuit and a control circuit. The front surface of main body 112 is stepped. An upper portion of the front surface of main body 112 is exposed to the outside. A lower portion of the front surface of main body 112 is covered with front cover 113.

[0041] A dip switch, push switch, LED, battery, etc. are arranged on the lower part of the front surface of main body 112. Therefore, the dip switch, push switch, LED, battery, etc. are arranged outside main body 112. Front cover 113 covers the parts arranged outside main body 112, such as the dip switch, push switch, LED, battery, etc.

[0042] Next, the communication device 1 of this embodiment will be further described with reference to Fig. 4. As shown in Fig. 4, the first mounting portion 13 includes a first protrusion 13a. The first protrusion 13a protrudes vertically from the housing main body 111. The first bundling member 121 described with reference to Fig. 3 bundles the first protrusion 13a to the vertical pipe PG1. Since the first mounting portion 13 includes the first protrusion 13a, the task of bundling the first mounting portion 13 to the vertical pipe PG1 using the first bundling member 121 is facilitated.

[0043] In this embodiment, the first attachment portion 13 includes an upper attachment portion 131 and a lower attachment portion 132. The upper attachment portion 131 is disposed on an upper portion of the housing body 111. The lower attachment portion 132 is disposed on a lower portion of the housing body 111. The upper attachment portion 131 is disposed in the center of the housing body 111 in the left-right direction (horizontal direction). Similarly, the lower attachment portion 132 is disposed in the center of the housing body 111 in the left-right direction (horizontal direction). The first protrusion 13a of the upper attachment portion 131 protrudes upward from the housing body 111.

[0044] As shown in FIG. 4, the upper mounting portion 131 and the lower mounting portion 132 may include a through hole H. In this embodiment, the through hole H penetrates the first protrusion 13a. The through hole H is used when mounting the communication device 1 on a wall. Specifically, when mounting the communication device 1 on a wall, a fastening member is inserted into the through hole H from the front side of the communication device 1 and fastened to the wall. As a result, the communication device 1 is mounted on the wall.

[0045] As shown in Fig. 4, the second mounting portion 14 includes a second protruding portion 14a. The second protruding portion 14a protrudes laterally from the housing main body 111. The second bundling member 122 described with reference to Fig. 3 bundling the second protruding portion 14a to the horizontal piping PG2. Since the second mounting portion 14 includes the second protruding portion 14a, the task of bundling the second mounting portion 14 to the horizontal piping PG2 using the second bundling member 122 becomes easier.

[0046] In this embodiment, the second attachment portion 14 includes a left attachment portion 141 and a right attachment portion 142. The left attachment portion 141 is disposed on the left side of the housing body 111. The right attachment portion 142 is disposed on the right side of the housing body 111. The left attachment portion 141 is disposed in the center of the housing body 111 in the up-down direction. Similarly, the right attachment portion 142 is disposed in the center of the housing body 111 in the up-down direction. The left side of the housing body 111 refers to one side of the housing body 111 in the lateral direction. The right side of the housing body 111 refers to the other side of the housing body 111 in the lateral direction (the opposite side to the one side).

[0047] The second protrusion 14a of the left side mounting portion 141 protrudes leftward from the housing body 111. The second protrusion 14a of the right side mounting portion 142 protrudes rightward from the housing body 111. The left side mounting portion 141 is an example of a "first side mounting portion." The right side mounting portion 142 is an example of a "second side mounting portion."

[0048] Next, the communication device 1 of this embodiment will be further described with reference to Figs. 5 and 6. As shown in Figs. 5 and 6, the first attachment portion 13 is disposed on the back surface 112a of the main body portion 112. More specifically, a part of the first attachment portion 13 is coupled to the back surface 112a, and the remaining part protrudes from the main body portion 112 (housing main body 111). For example, the main body portion 112 and the first attachment portion 13 may be integrally formed. Note that the back surface 112a of the main body portion 112 constitutes the back surface of the housing main body 111. The back surface 112a of the main body portion 112 is an example of an "arrangement surface".

[0049] In this embodiment, a lower portion of the upper mounting portion 131 is connected to the rear surface 112a, and an upper portion of the upper mounting portion 131 protrudes from the main body portion 112 (housing main body 111). Also, an upper portion of the lower mounting portion 132 is connected to the rear surface 112a, and a lower portion of the lower mounting portion 132 protrudes from the main body portion 112 (housing main body 111).

[0050] Next, the communication device 1 of this embodiment will be further described with reference to Figures 4 and 5. As shown in Figures 4 and 5, the first attachment portion 13 has a first stopper portion 13b. The first stopper portion 13b protrudes in a direction perpendicular to the vertical direction (up-down direction) and restricts the movement of the first binding member 121 described with reference to Figure 3 in the vertical direction (up-down direction).

[0051] As shown in Fig. 5, in this embodiment, the first stopper portion 13b protrudes forward. Specifically, the first stopper portion 13b is coupled to the first protruding portion 13a and protrudes forward from the front surface of the first protruding portion 13a. In other words, the first stopper portion 13b protrudes on the side opposite to the first contact surface S1 side described with reference to Fig. 6. The first bundling member 121 described with reference to Fig. 3 bundles the first protruding portion 13a to the vertical pipe PG1 between the first stopper portion 13b and the housing main body 111.

[0052] 4 and 5, the first stopper portion 13b of the upper mounting portion 131 may be disposed on the upper end side of the first protrusion portion 13a of the upper mounting portion 131. The first binding member 121 binds the first protrusion portion 13a of the upper mounting portion 131 to the vertical piping PG1 between the first stopper portion 13b of the upper mounting portion 131 and the upper surface of the housing body 111.

[0053] 4 and 5, the first stopper portion 13b of the lower mounting portion 132 may be disposed on the lower end side of the first protruding portion 13a of the lower mounting portion 132. The first binding member 121 binds the first protruding portion 13a of the lower mounting portion 132 to the vertical piping PG1 between the first stopper portion 13b of the lower mounting portion 132 and the lower surface of the housing body 111.

[0054] According to this embodiment, the first attachment portion 13 has the first stopper portion 13b, so that the first binding member 121 is less likely to come off the first protruding portion 13a. Therefore, the attitude of the communication device 1 can be stabilized.

[0055] Next, the communication device 1 of this embodiment will be described with reference to Figs. 6 to 8. As shown in Figs. 6 to 8, the second attachment portion 14 is disposed on the back surface 112a of the main body portion 112. Specifically, the second attachment portion 14 further has an attachment main body portion 14c, and the attachment main body portion 14c is joined to the back surface 112a of the main body portion 112. The second protrusion portion 14a protrudes in the lateral direction (left-right direction) from the attachment main body portion 14c. Note that the main body portion 112 and the second attachment portion 14 may be integrally formed.

[0056] In this embodiment, the mounting body 14c of the left mounting portion 141 is joined to the left side of the rear surface 112a, and the second protrusion 14a of the left mounting portion 141 protrudes from the left side surface of the mounting body 14c. The mounting body 14c of the right mounting portion 142 is joined to the right side of the rear surface 112a, and the second protrusion 14a of the right mounting portion 142 protrudes from the right side surface of the mounting body 14c.

[0057] Next, the communication device 1 of this embodiment will be further described with reference to Figures 4, 7, and 8. As shown in Figures 4, 7, and 8, the second attachment portion 14 has a second stopper portion 14b. The second stopper portion 14b protrudes in a direction perpendicular to the lateral direction (left-right direction) and restricts the movement of the second binding member 122 described with reference to Figure 3 in the lateral direction (left-right direction).

[0058] As shown in Figures 7 and 8, in this embodiment, the second stopper portion 14b protrudes forward. Specifically, the second stopper portion 14b is connected to the second protruding portion 14a and protrudes forward from the front surface of the second protruding portion 14a. In other words, the second stopper portion 14b protrudes on the side opposite to the second contact surface S2 side described with reference to Figure 6. The second binding member 122 described with reference to Figure 3 binds the second protruding portion 14a to the horizontal pipe PG2 between the second stopper portion 14b and the mounting body portion 14c.

[0059] 4, 7, and 8, the second stopper portion 14b of the left mounting portion 141 may be disposed on the left end side of the second protrusion portion 14a of the left mounting portion 141. The second binding member 122 binds the second protrusion portion 14a of the left mounting portion 141 to the horizontal piping PG2 between the second stopper portion 14b of the left mounting portion 141 and the left surface of the mounting body portion 14c.

[0060] 4, 7, and 8, the second stopper portion 14b of the right mounting portion 142 may be disposed on the right end side of the second protrusion portion 14a of the right mounting portion 142. The second binding member 122 binds the second protrusion portion 14a of the right mounting portion 142 to the horizontal piping PG2 between the second stopper portion 14b of the right mounting portion 142 and the right surface of the mounting body portion 14c.

[0061] According to this embodiment, since the second attachment portion 14 has the second stopper portion 14b, the second binding member 122 is less likely to come off the second protruding portion 14a. Therefore, the attitude of the communication device 1 can be stabilized.

[0062] Next, the communication device 1 of this embodiment will be further described with reference to Figs. 6 to 8. As shown in Figs. 6 to 8, the first attachment portion 13 has a first contact surface S1. The first contact surface S1 contacts the vertical pipe PG1 described with reference to Fig. 3. In this embodiment, the first contact surface S1 is the rear surface of the first attachment portion 13. The first contact surface S1 is bent at a first bent portion BD1 extending along the vertical direction (up-down direction). Specifically, the first contact surface S1 is bent in a V-shape. The first contact surface S1 contacts the vertical pipe PG1 on both the left and right sides of the first bent portion BD1. In other words, the first contact surface S1 is bent so as to surround the vertical pipe PG1.

[0063] Specifically, as shown in FIG. 6, the first contact surface S1 includes a left contact surface S11 and a right contact surface S12. The portion of the first contact surface S1 that is to the left of the first bent portion BD1 is the left contact surface S11. The portion of the first contact surface S1 that is to the right of the first bent portion BD1 is the right contact surface S12. As shown in FIGS. 7 and 8, the left contact surface S11 is an inclined surface that slopes diagonally left rearward from the first bent portion BD1. The right contact surface S12 is an inclined surface that slopes diagonally right rearward from the first bent portion BD1. Therefore, the left contact surface S11 and the right contact surface S12 face each other in the right-right direction behind the first bent portion BD1.

[0064] According to this embodiment, the first contact surface S1 is bent in a V-shape, so that the vertical pipe PG1 comes into contact with two points of the first contact surface S1 regardless of the diameter of the vertical pipe PG1. Specifically, the vertical pipe PG1 comes into contact with the left contact surface S11 and the right contact surface S12. Therefore, the posture of the communication device 1 can be more stable than a configuration in which the first mounting portion 13 and the vertical pipe PG1 come into contact at one point. For example, when the first contact surface S1 is arc-shaped, there is a possibility that the first mounting portion 13 and the vertical pipe PG1 come into contact at one point. Specifically, when the diameter of the arc-shaped first contact surface S1 is larger than the diameter of the vertical pipe PG1, the first mounting portion 13 and the vertical pipe PG1 come into contact at one point. Therefore, according to this embodiment, the posture of the communication device 1 can be more stable than a configuration in which the first contact surface S1 is arc-shaped.

[0065] Next, the communication device 1 of this embodiment will be further described with reference to Figs. 5 and 6. As shown in Figs. 5 and 6, the second mounting portion 14 has a second contact surface S2. The second contact surface S2 contacts the horizontal pipe PG2 described with reference to Fig. 3. More specifically, the mounting body portion 14c has the second contact surface S2. The second contact surface S2 is the rear surface of the mounting body portion 14c. As shown in Fig. 6, the second contact surface S2 is bent at a second bent portion BD2 extending along the horizontal direction (left-right direction). More specifically, the second contact surface S2 is bent in a V-shape. The second contact surface S2 contacts the horizontal pipe PG2 on both the upper and lower sides of the second bent portion BD2. That is, the second contact surface S2 is bent so as to surround the horizontal pipe PG2.

[0066] Specifically, as shown in FIG. 6, the second contact surface S2 includes an upper contact surface S21 and a lower contact surface S22. A portion of the second contact surface S2 that is above the second bent portion BD2 is the upper contact surface S21. A portion of the second contact surface S2 that is below the second bent portion BD2 is the lower contact surface S22. As shown in FIG. 5, the upper contact surface S21 is an inclined surface that slopes obliquely upward and rearward from the second bent portion BD2. The lower contact surface S22 is an inclined surface that slopes obliquely downward and rearward from the second bent portion BD2. Therefore, the upper contact surface S21 and the lower contact surface S22 face each other in the up-down direction rearward from the second bent portion BD2.

[0067] According to this embodiment, the second contact surface S2 is bent in a V-shape, so that the horizontal pipe PG2 comes into contact with two points on the second contact surface S2 regardless of the diameter of the horizontal pipe PG2. Specifically, the horizontal pipe PG2 comes into contact with the upper contact surface S21 and the lower contact surface S22. Therefore, the posture of the communication device 1 can be more stable than a configuration in which the second attachment portion 14 and the horizontal pipe PG2 come into contact at one point. For example, when the second contact surface S2 is arc-shaped, there is a possibility that the second attachment portion 14 and the horizontal pipe PG2 come into contact at one point. Specifically, when the diameter of the arc-shaped second contact surface S2 is larger than the diameter of the horizontal pipe PG2, the second attachment portion 14 and the horizontal pipe PG2 come into contact at one point. Therefore, according to this embodiment, the posture of the communication device 1 can be more stable than a configuration in which the second contact surface S2 is arc-shaped.

[0068] Next, the communication device 1 of this embodiment will be described with reference to Fig. 9. Fig. 9 is a diagram showing the communication device 1 arranged on the L-shaped portion PGL of the gas pipe PG. In the example shown in Fig. 9, the lower attachment portion 132 is attached to the vertical pipe PG1, and the right attachment portion 142 is attached to the horizontal pipe PG2.

[0069] 9, when the lower mounting portion 132 is attached to the vertical pipe PG1, the first bundling member 121 bundles the first protrusion 13a of the lower mounting portion 132 to the vertical pipe PG1. When the right mounting portion 142 is attached to the horizontal pipe PG2, the second bundling member 122 bundles the second protrusion 14a of the left mounting portion 141 to the horizontal pipe PG2.

[0070] Next, the communication device 1 of this embodiment will be described with reference to Fig. 10 to Fig. 13. First, the communication device 1 of this embodiment will be described with reference to Fig. 10. Fig. 10 is a diagram showing the communication device 1 disposed in the first L-shaped portion PGL1 of the gas pipe PG. For ease of understanding, the first stopper portion 13b and the second stopper portion 14b described with reference to Figs. 4 to 9 are omitted in Figs. 10 to 13.

[0071] 10, in the first L-shaped portion PGL1, one end of the bent portion PG3 faces downward and the other end of the bent portion PG3 faces left. Therefore, the vertical pipe PG1 extends downward (first direction) from the bent portion PG3. Also, the horizontal pipe PG2 extends left (second direction) from the bent portion PG3.

[0072] When the communication device 1 is disposed on the first L-shaped portion PGL1, the lower mounting portion 132 is attached to the vertical pipe PG1, and the left mounting portion 141 is attached to the horizontal pipe PG2. More specifically, the first bundling member 121 binds the first protrusion 13a of the lower mounting portion 132 to the vertical pipe PG1. The second bundling member 122 binds the second protrusion 14a of the left mounting portion 141 to the horizontal pipe PG2.

[0073] Fig. 11 is a diagram showing a communication device 1 disposed in the second L-shaped portion PGL2 of the gas pipe PG. As shown in Fig. 11, in the second L-shaped portion PGL2, one end of the bent portion PG3 faces upward, and the other end of the bent portion PG3 faces left. Therefore, the vertical pipe PG1 extends upward (third direction) from the bent portion PG3. In addition, the horizontal pipe PG2 extends leftward (second direction) from the bent portion PG3.

[0074] When the communication device 1 is disposed on the second L-shaped portion PGL2, the upper mounting portion 131 is attached to the vertical pipe PG1, and the left mounting portion 141 is attached to the horizontal pipe PG2. More specifically, the first protrusion 13a of the upper mounting portion 131 is fastened to the vertical pipe PG1 by the first fastening member 121. Moreover, the second protrusion 14a of the left mounting portion 141 is fastened to the horizontal pipe PG2 by the second fastening member 122.

[0075] Fig. 12 is a diagram showing a communication device 1 disposed in the third L-shaped portion PGL3 of the gas pipe PG. As shown in Fig. 12, in the third L-shaped portion PGL3, one end of the bent portion PG3 faces upward, and the other end of the bent portion PG3 faces right. Therefore, the vertical pipe PG1 extends upward (third direction) from the bent portion PG3. In addition, the horizontal pipe PG2 extends rightward (fourth direction) from the bent portion PG3.

[0076] When the communication device 1 is disposed on the third L-shaped portion PGL3, the upper mounting portion 131 is attached to the vertical pipe PG1, and the right mounting portion 142 is attached to the horizontal pipe PG2. More specifically, the first bundling member 121 binds the first protrusion 13a of the upper mounting portion 131 to the vertical pipe PG1. Furthermore, the second bundling member 122 binds the second protrusion 14a of the right mounting portion 142 to the horizontal pipe PG2.

[0077] Fig. 13 is a diagram showing a communication device 1 disposed in a fourth L-shaped portion PGL4 of a gas pipe PG. As shown in Fig. 13, in the fourth L-shaped portion PGL4, one end of the bent portion PG3 faces downward, and the other end of the bent portion PG3 faces right. Therefore, the vertical pipe PG1 extends downward (first direction) from the bent portion PG3. In addition, the horizontal pipe PG2 extends right (fourth direction) from the bent portion PG3.

[0078] When the communication device 1 is disposed on the fourth L-shaped portion PGL4, the lower mounting portion 132 is attached to the vertical pipe PG1, and the right mounting portion 142 is attached to the horizontal pipe PG2. More specifically, the first bundling member 121 binds the first protrusion 13a of the lower mounting portion 132 to the vertical pipe PG1. The second bundling member 122 binds the second protrusion 14a of the right mounting portion 142 to the horizontal pipe PG2.

[0079] The first embodiment of the present invention has been described above with reference to Figs. 1 to 13. According to this embodiment, the communication device 1 can be attached to the vertical pipe PG1 and the horizontal pipe PG2. Therefore, the communication device 1 does not rotate around the vertical pipe PG1 as a central axis. Moreover, the communication device 1 does not rotate around the horizontal pipe PG2 as a central axis. Therefore, the attitude of the communication device 1 can be made more stable.

[0080] Furthermore, according to this embodiment, since the communication device 1 is attached to the vertical pipe PG1 and the horizontal pipe PG2, the communication device 1 can be easily set to an upright position.

[0081] Furthermore, according to this embodiment, even if the gas pipe PG around the meter 2 is bent, the communication device 1 can be disposed in the gas pipe PG.

[0082] Furthermore, according to this embodiment, the communication device 1 can be arranged in the first L-shaped portion PGL1 to the fourth L-shaped portion PGL4. Therefore, no matter in which direction the gas pipe PG around the meter 2 is bent, the communication device 1 can be arranged in the gas pipe PG.

[0083] In this embodiment, the upper attachment portion 131 is disposed at the center in the left-right direction (horizontal direction) of the housing body 111, but the upper attachment portion 131 may be disposed on the right or left side of the center of the housing body 111. Similarly, the lower attachment portion 132 may be disposed on the right or left side of the center of the housing body 111.

[0084] In this embodiment, the left attachment part 141 is disposed at the center of the housing body 111 in the up-down direction, but the left attachment part 141 may be disposed above or below the center of the housing body 111. Similarly, the right attachment part 142 may be disposed above or below the center of the housing body 111.

[0085] [Embodiment 2] Next, a second embodiment of the present invention will be described with reference to Fig. 14. However, differences from the first embodiment will be described, and a description of the same points as in the first embodiment will be omitted. The second embodiment differs from the first embodiment in the configuration of the first attachment portion 13.

[0086] Fig. 14 is a front view of the communication device 1 of this embodiment. As shown in Fig. 14, in this embodiment, the first protrusion 13a has a first notch 13c1 and a second notch 13c2.

[0087] The first notch 13c1 and the second notch 13c2 face each other in the horizontal direction (left-right direction). The first notch 13c1 and the second notch 13c2 extend in the horizontal direction (left-right direction). More specifically, the first notch 13c1 is formed on the left side of the first protruding portion 13a and recessed to the right from the left surface of the first protruding portion 13a. Similarly, the second notch 13c2 is formed on the right side of the first protruding portion 13a and recessed to the left from the right surface of the first protruding portion 13a.

[0088] In this embodiment, the first binding member 121 described with reference to FIG. 3 is fitted into a pair of left and right notches (first notch 13c1 and second notch 13c2) when binding the first protruding portion 13a to the vertical pipe PG1.

[0089] Above, the second embodiment of the present invention has been described with reference to Fig. 14. According to this embodiment, the first bundling member 121 can be fitted into a pair of left and right notches (first notch 13c1 and second notch 13c2). Therefore, the first bundling member 121 is less likely to come off the first protruding portion 13a. Therefore, the attitude of the communication device 1 can be stabilized.

[0090] Although the communication device 1 shown in FIG. 14 has the first stopper portion 13b, if the first protrusion 13a has a pair of left and right notches (first notch 13c1 and second notch 13c2), the first stopper portion 13b may be omitted.

[0091] Similarly to the first protrusion 13a, the second protrusion 14a may have a pair of upper and lower notches. By having the second protrusion 14a have a pair of upper and lower notches, the second binding member 122 is less likely to come off the second protrusion 14a. This makes it possible to stabilize the attitude of the communication device 1. In this case, the second stopper portion 14b may be omitted.

[0092] In the present embodiment, the first protrusion 13a has a pair of left and right notches, but the first protrusion 13a may have a band-passing hole for passing the first binding member 121 instead of or in addition to the pair of left and right notches. Similarly, the second protrusion 14a may have a band-passing hole for passing the second binding member 122 instead of or in addition to the pair of upper and lower notches.

[0093] [Embodiment 3] Next, a third embodiment of the present invention will be described with reference to Figures 15 to 18. However, differences from the first and second embodiments will be described, and a description of the same aspects as the first and second embodiments will be omitted. The third embodiment differs from the first embodiment in the configuration of the second attachment portion 14.

[0094] FIG. 15 is a rear view of the communication device 1 of this embodiment. FIG. 16 is a front view of the communication device 1 of this embodiment. As shown in FIG. 15 and FIG. 16, in this embodiment, the second protrusion 14a does not protrude from the housing main body 111. That is, as shown in FIG. 15, the entire second protrusion 14a and the second stopper portion 14b face the rear face 112a of the main body portion 112. In other words, the entire second protrusion 14a and the second stopper portion 14b overlap with the rear face 112a of the main body portion 112 in the front-rear direction.

[0095] Fig. 17 is a bottom view of the communication device 1 of the present embodiment. Fig. 18 is a right side view of the communication device 1 of the present embodiment. As shown in Figs. 17 and 18, the second protrusion 14a and the second stopper portion 14b form a gap between the second protrusion 14a and the rear surface 112a of the main body portion 112. The presence of a gap between the second protrusion 14a and the second stopper portion 14b and the rear surface 112a of the main body portion 112 makes it possible to fasten the second protrusion 14a to the horizontal pipe PG2 using the second fastening member 122 described with reference to Fig. 3.

[0096] The third embodiment of the present invention has been described above with reference to Fig. 15 to Fig. 18. According to this embodiment, similarly to the first and second embodiments, the attitude of the communication device 1 can be stabilized.

[0097] [Embodiment 4] Next, a fourth embodiment of the present invention will be described with reference to Figures 19 to 21. However, differences from the first to third embodiments will be described, and descriptions of the same matters as the first to third embodiments will be omitted. The fourth embodiment differs from the first to third embodiments in that the communication device 1 includes a plurality of upper attachment parts 131 and a plurality of lower attachment parts 132.

[0098] Fig. 19 is a front view of the communication device 1 of this embodiment. Fig. 20 is a rear view of the communication device 1 of this embodiment. Fig. 21 is a bottom view of the communication device 1 of this embodiment. As shown in Figs. 19 to 21, the communication device 1 of this embodiment includes an upper mounting block 131BL and a lower mounting block 132BL.

[0099] The upper mounting block 131BL includes a first upper mounting portion 131A to a third upper mounting portion 131C. In addition, the upper mounting block 131BL has two third cutouts 13d and a through hole H.

[0100] The first to third upper mounting portions 131A to 131C are aligned in the horizontal direction (left-right direction). In this embodiment, the first to third upper mounting portions 131A to 131C are aligned in this order from left to right. The first protrusions 13a of the first to third upper mounting portions 131A to 131C each have the first notch 13c1 and the second notch 13c2 described with reference to FIG. 14.

[0101] The two third notches 13d each extend in the vertical direction (up-down direction). One of the two third notches 13d is formed at the boundary between the first upper mounting portion 131A and the second upper mounting portion 131B, and communicates with the second notch 13c2 of the first upper mounting portion 131A and the first notch 13c1 of the second upper mounting portion 131B. The other of the two third notches 13d is formed at the boundary between the second upper mounting portion 131B and the third upper mounting portion 131C, and communicates with the second notch 13c2 of the second upper mounting portion 131B and the first notch 13c1 of the third upper mounting portion 131C.

[0102] By providing the third notch 13d at the boundary between the first upper mounting portion 131A and the second upper mounting portion 131B, the first binding member 121 can be fitted into the second notch 13c2 of the first upper mounting portion 131A and the first notch 13c1 of the second upper mounting portion 131B. Similarly, by providing the third notch 13d at the boundary between the second upper mounting portion 131B and the third upper mounting portion 131C, the first binding member 121 can be fitted into the second notch 13c2 of the second upper mounting portion 131B and the first notch 13c1 of the third upper mounting portion 131C.

[0103] The lower mounting block 132BL includes a first lower mounting portion 132A to a third lower mounting portion 132C. In addition, the lower mounting block 132BL has two third cutouts 13d and a through hole H.

[0104] The first to third lower mounting portions 132A to 132C are aligned in the horizontal direction (left-right direction). In this embodiment, the first to third lower mounting portions 132A to 132C are aligned in this order from left to right. The first protruding portion 13a of each of the first to third lower mounting portions 132A to 132C has the first notch 13c1 and the second notch 13c2 described with reference to FIG.

[0105] The two third notches 13d each extend in the vertical direction (up-down direction). One of the two third notches 13d is formed at the boundary between the first lower mounting portion 132A and the second lower mounting portion 132B, and communicates with the second notch 13c2 of the first lower mounting portion 132A and the first notch 13c1 of the second lower mounting portion 132B. The other of the two third notches 13d is formed at the boundary between the second lower mounting portion 132B and the third lower mounting portion 132C, and communicates with the second notch 13c2 of the second lower mounting portion 132B and the first notch 13c1 of the third lower mounting portion 132C.

[0106] By providing the third notch 13d at the boundary between the first lower mounting portion 132A and the second lower mounting portion 132B, the first binding member 121 can be fitted into the second notch 13c2 of the first lower mounting portion 132A and the first notch 13c1 of the second lower mounting portion 132B. Similarly, by providing the third notch 13d at the boundary between the second lower mounting portion 132B and the third lower mounting portion 132C, the first binding member 121 can be fitted into the second notch 13c2 of the second lower mounting portion 132B and the first notch 13c1 of the third lower mounting portion 132C.

[0107] The fourth embodiment of the present invention has been described above with reference to Fig. 19 to Fig. 21. According to this embodiment, the first mounting portion 13 for mounting the vertical pipe PG1 can be selected from the first upper mounting portion 131A to the third upper mounting portion 131C and the first lower mounting portion 132A to the third lower mounting portion 132C in accordance with the shape of the bent portion PG3 of the gas pipe PG. Therefore, the communication device 1 can be disposed in the L-shaped portion PGL of the gas pipe PG.

[0108] Furthermore, according to this embodiment, the first mounting portion 13 for mounting the vertical piping PG1 can be selected from among the first upper mounting portion 131A to the third upper mounting portion 131C and the first lower mounting portion 132A to the third lower mounting portion 132C, thereby enabling the installation position of the communication device 1 to be adjusted to a position with a better communication environment.

[0109] In addition, although the communication device 1 of this embodiment has multiple upper mounting portions 131 and multiple lower mounting portions 132, the communication device 1 may have multiple upper mounting portions 131 and one lower mounting portion 132, or may have one upper mounting portion 131 and multiple lower mounting portions 132.

[0110] Further, in this embodiment, the number of upper attachment portions 131 and the number of lower attachment portions 132 are the same, but the number of upper attachment portions 131 and the number of lower attachment portions 132 do not have to be the same.

[0111] In addition, in this embodiment, the communication device 1 includes three upper attachment portions 131, but the communication device 1 may include two upper attachment portions 131, or may include four or more upper attachment portions 131. Similarly, the communication device 1 may include two lower attachment portions 132, or may include four or more lower attachment portions 132.

[0112] [Embodiment 5] Next, a fifth embodiment of the present invention will be described with reference to Fig. 22 and Fig. 23. However, differences from the first to fourth embodiments will be described, and descriptions of the same aspects as the first to fourth embodiments will be omitted. The fifth embodiment differs from the first to fourth embodiments in that the communication device 1 includes a plurality of left attachment portions 141 and a plurality of right attachment portions 142.

[0113] Fig. 22 is a front view of the communication device 1 of this embodiment. Fig. 23 is a rear view of the communication device 1 of this embodiment. As shown in Figs. 22 and 23, the communication device 1 of this embodiment includes a first left attachment portion 141A to a third left attachment portion 141C and a first right attachment portion 142A to a third right attachment portion 142C.

[0114] The first left mounting portion 141A to the third left mounting portion 141C are aligned in the vertical direction (up-down direction). In this embodiment, the first left mounting portion 141A to the third left mounting portion 141C are aligned in this order from top to bottom. Similarly, the first right mounting portion 142A to the third right mounting portion 142C are aligned in the vertical direction (up-down direction). In this embodiment, the first right mounting portion 142A to the third right mounting portion 142C are aligned in this order from top to bottom.

[0115] The fifth embodiment of the present invention has been described above with reference to Fig. 22 and Fig. 23. According to this embodiment, the second mounting portion 14 for mounting the horizontal pipe PG2 can be selected from the first left mounting portion 141A to the third left mounting portion 141C and the first right mounting portion 142A to the third right mounting portion 142C in accordance with the shape of the bent portion PG3 of the gas pipe PG. Therefore, the communication device 1 can be disposed in the L-shaped portion PGL of the gas pipe PG.

[0116] Furthermore, according to this embodiment, the second mounting portion 14 for mounting the horizontal piping PG2 can be selected from among the first left side mounting portion 141A to the third left side mounting portion 141C and the first right side mounting portion 142A to the third right side mounting portion 142C, thereby enabling the installation position of the communication device 1 to be adjusted to a position with a better communication environment.

[0117] In addition, although the communication device 1 of this embodiment has multiple left side mounting portions 141 and multiple right side mounting portions 142, the communication device 1 may have multiple left side mounting portions 141 and one right side mounting portion 142, or may have one left side mounting portion 141 and multiple right side mounting portions 142.

[0118] In addition, in this embodiment, the number of left attachment portions 141 and the number of right attachment portions 142 are the same, but the number of left attachment portions 141 and the number of right attachment portions 142 do not have to be the same.

[0119] In addition, in this embodiment, the communication device 1 includes three left side mounting portions 141, but the communication device 1 may include two left side mounting portions 141, or may include four or more left side mounting portions 141.
