As shown in FIGS. 1 to 6, the present invention is a detector X including sensors 12 to 52 that detect changes in the external environment, and the sensors 12 to 52 are connected to an opening B formed in the housing A. Sensor accommodating portions 90a to 90e for accommodating the sensors 12 to 52 are formed so as to be detachable, and the sensor accommodating portions 90a to 90e include attachment portions 91a to 91e to which the sensors 12 to 52 and other devices 100 can be attached and detached.

  The opening B is covered with a lid C, and windows a to e for visually recognizing the sensors 12 to 52 are formed in the lid C. Transparent members a1 to e1 are fitted in the windows a to e, respectively.

  In the present embodiment, a sensor array system X including a sensor unit 10 having sensors 12 and including a plurality of such sensor units will be described. The sensor array system X may be any device as long as it is a portable aspect or an aspect that is installed indoors or outdoors on a wall surface. This embodiment demonstrates the case where it is set as the aspect of portability.

  In the present embodiment, a case where the sensor array system X includes five sensor units 10 to 50 will be described.

  Adjacent sensor units are connected by a pipe 60 through which ambient atmospheric gas flows, and a gas flow passage 70 is formed for flowing ambient atmospheric gas from the upstream sensor unit 10 to the downstream sensor unit 50 in order. The

For example, in the sensor unit 10, the sensor block 11 is formed with a locking hole portion connected to the pipe 60 on the upstream side where the atmospheric gas sucked from the intake port 1 flows in and on the downstream side where the atmospheric gas flows out. . That is, the sensor block 11 is formed with an upstream side locking hole portion 11a into which atmospheric gas flows and a downstream side locking hole portion 11b from which atmospheric gas flows out. In the said upstream side locking hole part 11a and the downstream side locking hole part 11b, each connects with the 1st piping 61 and the 2nd piping 62 (FIG. 5).
The pipe 60 is locked in the locking hole by the O-ring 16.

  The sensor unit 10 is supported by a sensor block 11, and detects a sensor 12 that detects a change in the external environment, a flow sensor 13 that measures the flow rate of the atmospheric gas, a sensor buffer 14 that buffers the atmospheric gas, and sucks the atmospheric gas. A pump 15 is provided. The atmospheric gas that has flowed into the sensor block 11 passes through the branch path 71 branched from the gas flow path 70 and flows into the sensor 12, and flows down through the flow sensor 13 and the sensor buffer 14.

  The other sensor units have the same configuration, that is, the sensor unit 20 includes a sensor block 21, a sensor 22, a flow sensor 23, a sensor buffer 24, and a pump 25. The sensor block 21 includes an upstream side locking hole 21a and a downstream side. A locking hole 21b is formed. The second piping 62 is connected to the upstream locking hole 21a, and the third piping 63 is connected to the downstream locking hole 21b.

  The sensor unit 30 includes a sensor block 31, a sensor 32, a flow sensor 33, a sensor buffer 34, and a pump 35, and an upstream locking hole 31 a and a downstream locking hole 31 b are formed in the sensor block 31. A third pipe 63 is connected to the upstream side locking hole 31a, and a fourth pipe 64 is connected to the downstream side locking hole 31b.

  The sensor unit 40 includes a sensor block 41, a sensor 42, a flow sensor 43, a sensor buffer 44, and a pump 45, and an upstream locking hole 41 a and a downstream locking hole 41 b are formed in the sensor block 41. The fourth pipe 64 is connected to the upstream side locking hole 41a, and the fifth pipe 65 is connected to the downstream side locking hole 41b.

  Further, the sensor unit 50 includes a sensor block 51, a sensor 52, a flow sensor 53, a sensor buffer 54, and a pump 55, and an upstream locking hole 51a and a downstream locking hole 51b are formed in the sensor block 51. The fifth pipe 65 is connected to the upstream side locking hole 51a. Since the sensor unit 50 is the most downstream unit, the downstream locking hole 51b may be configured so that the atmospheric gas does not flow downstream. Therefore, the downstream side locking hole 51b may be sealed, and the downstream side locking hole part may not be provided.

The atmospheric gas that has flowed into the sensor blocks 21 to 51 passes through the branch paths 72 to 75 branched from the gas flow path 70 and flows into the sensors 22 to 52, respectively, and flows through the flow sensors 23 to 53 and the sensor buffers 24 to 54, respectively. Flow down.
It is possible to output a signal including information such as the flow rate from the flow sensors 23 to 53. At this time, monitoring is performed by connecting to an external device that can receive the signal and display information such as the flow rate. Thus, clogging of piping due to dirt or the like, failure of the pump unit, etc. can be detected at an early stage.

  The atmospheric gas discharged from the pumps 15 to 55 is discharged from the exhaust port 2 to the outside of the sensor array system X via the out buffer 80.

  Each of the sensor units 10 to 50 includes sensors 12 to 52 that detect changes in the external environment. As such a sensor, a gas sensor such as an oxygen sensor, a CO sensor, a city gas sensor, and an LP gas sensor can be used, but is not limited thereto.

  The gas sensor may be in any form as long as it detects the gas to be detected. For example, an oxygen sensor can detect oxygen gas, a CO sensor can detect carbon monoxide gas generated by incomplete combustion, and a city gas sensor can detect a leak gas such as hydrocarbon gas. A semiconductor sensor element, a contact combustion sensor element, an electrochemical sensor, and the like can be used.

  The sensor array system X receives an alarm signal from the calculation means when a later-described calculation means (not shown), for example, determines that the sensor 12 continuously detects the gas to be detected that is higher than or equal to the alarm level. It is connected with the sound emission part (not shown) which emits. The sound emitting unit may be incorporated in the sensor array system X.

The calculation means includes a concentration calculation unit (not shown) that calculates the detected gas concentration based on the output of the sensor 12 that detects the detected gas. Further, when the sensor 12 continuously detects the detected gas concentration equal to or higher than the alarm level, the calculation means controls to transmit an alarm signal to the sound emitting unit and issue an alarm by the sound emitting unit.
In the sensor array system X of the present invention, a display unit (not shown) for displaying the result of the calculation means may be provided in the housing so that the detected gas concentration and the like can be displayed.

  For example, the sensor 12 is accommodated in the sensor accommodating portion 90a. The sensor accommodating portion 90a can be accessed by opening the lid portion C covering the opening B. Moreover, the sensor accommodating part 90a is provided with the attaching part 91a which can attach or detach the sensor 12 and the other apparatus 100. FIG.

As long as the attachment part 91a is an aspect which can attach or detach the sensor 12 and the other apparatus 100, what kind of aspect may be sufficient as it. For example, the sensor 12 is supported by the sensor block 11, and the branch path 71 and the sensor 12 are connected via a cylindrical member 92a that connects them. That is, the sensor 12 has an engaging recess 12a for engaging the cylindrical member 92a.
Accordingly, the other device 100 may be configured to be connected via the tubular member 92a after the sensor 12 is detached. For this reason, the other device 100 may have an engaging recess 100a for engaging the cylindrical member 92a.

  The other sensors 22 to 52 are also housed in the sensor housing portions 90b to 90e, respectively, similarly to the sensor 12, and the branch paths 72 to 75 and the sensors 22 to 52 are connected via cylindrical members 92b to 92e that connect them. Connected. That is, the sensors 22 to 52 have engagement recesses 22a to 52a for engaging the cylindrical members 92b to 92e. Therefore, the mounting portions 91b to 91e in the sensor housing portions 90b to 90e are also configured so that other devices 100 can be attached and detached.

  The other device 100 is not particularly limited, and may be a measuring device such as a flow meter, for example. For the purpose of detecting a special gas species, the other device 100 may be a pyrolysis furnace (unit) or the like, or a dummy sensor or a sealing material.

  As in this configuration, the sensor housing portions 90a to 90e are formed so that the sensors 12 to 52 can be attached and detached from the opening B, and the attachment portions 91a to 91e that can attach and remove the sensors 12 to 52 and the other devices 100 are provided. The sensors 12 to 52 can be easily attached and detached from the opening B, and after the sensors 12 to 52 are attached and detached, another device 100 can be easily attached and detached from the opening B. Therefore, for example, when the other device 100 is a measuring device such as a flow meter, a desired measurement can be easily performed simply by removing the sensors 12 to 52 and attaching the measuring device to the mounting portions 91a to 91e. Can do.
