  Next, referring to FIG. 6, an example of the embodiment of the method for specifying the position of smoke generation of the present invention will be described.

  As shown in FIG. 6, the method of specifying a smoke generation position according to the present invention is, for example, the above-mentioned movable smoke in a computer room R or the like provided with a fixed smoke detection device 100 which is a fixed device. It can carry out using detection device 1.

  Here, the fixed smoke detection device 100 will be briefly described. The fixed type smoke detection apparatus 100 is aspirated through the sampling pipe 102 and the sampling pipe 102 having the sampling hole for suctioning the air in the computer room R circulated as indicated by the arrow by the air conditioner 103. A computer room which is provided with a suction type smoke detector main body 101 for detecting smoke in the air, which is disposed in the flow path of the air flow circulated in the space under the floor in the computer room R, and which is a protected space. It is provided in R as a fixed device at all times. The equipment configuration and the like of the smoke detection device main body 101 in the fixed smoke detection device 100 can be the same as the smoke detection device main body 5 in the movable smoke detection device 1 described above.

  In the computer room R, when smoke is generated from the computer of any of the racks 104, the fixed smoke detection device 100 first detects the smoke. If the smoke detected by the fixed smoke detection device 100 is at a stage where it can not be confirmed with the naked eye, the position of smoke generation that can be identified by the fixed smoke detection device 100 is up to the protective range. By using the movable smoke detection device 1, the generation position of smoke can be specified within a narrow range.

  That is, when smoke is generated in the computer room R, the stationary smoke detection device 100 provided as a fixed device at all times detects the generation of smoke, and as shown in FIG. The storage portion 7 of the first embodiment is held on the body by the shoulder strap 8 and the grip portion 4b of the sampling tube 4 is gripped, and smoke is detected in that state, the entire smoke detection device 1 movable in the computer room R. By moving the position or the position of the sampling tube 4 itself, the smoke source position is specified. Specifically, the smoke detector 1 is moved toward the respective racks 104 while detecting smoke, or the position of the sampling tube 4 itself is moved within each rack 104 to The generation position of the smoke is specified based on the detected amount of smoke displayed on the display unit 5a. Thereby, even if the generated smoke can not be confirmed with the naked eye, the generation position of the smoke can be specified within a narrow range. The smoke detector main body 5 of the movable smoke detector 1 has a lower sensitivity than the smoke detector main body 101 of the fixed smoke detector 100 in advance (for example, 2.5 times the smoke concentration at which the fixed type operates). Can be set to perform the step of identifying the location of smoke generation by the mobile smoke sensing device 1 described above.

  In the example shown in FIG. 6, at the tip of the sampling pipe 4 of the movable smoke detection device 1, a blowoff portion 4c is provided which is blown downwind by the air flow in the protected space, as will be understood in detail by the enlarged view. It has become By providing the blow-off portion 4c, the direction of the air flow in the protected space (including the direction of the air flow in each rack 104) can be confirmed, and smoke is detected with the sampling hole 4a directed to the windward side It is possible to move the whole of the movable smoke detection device 1 or the sampling tube 4 itself. In addition, even when the generation position of smoke is specified, it is possible to easily confirm that the object of investigation is upwind.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to said embodiment, A various change etc. are possible within the range of the summary of this invention.

  For example, in the computer room R, the fixed smoke detection device 100 may be addressable, and a plurality of the same may be provided, and the fixed smoke detection device 100 operates the range in which the mobile smoke detection device 1 is moved. After narrowing down to the protective range of the device 100, the step of identifying the location of smoke generation by the mobile smoke detection device 1 may be performed.

  Also, when performing the step of specifying the position of smoke generation by the movable smoke detection device 1, it may be performed while changing the detection sensitivity of smoke, for example, as described above, the sensitivity adjustment means Responding to the increase in the amount of smoke detected as it approaches the generation position, changing the smoke detection sensitivity low and changing the magnification of the display scale by the display unit 5a, thereby making the smoke generation position smoother It may be possible to narrowly specify.

  Also, when performing the step of specifying the smoke generation position by the movable smoke detection device 1, the position of the sampling pipe 4 is moved, and after stopping for a predetermined time at that position, it is judged whether it is the fire generation position or not. You may do so. In that case, for example, a timer and an acoustic unit are provided in the holding unit 4b of the sampling tube 4, and when the movement of the sampling tube 4 is stopped, the timer is started and the operator is notified by voice etc. You may

  In addition, when performing the step of specifying the generation position of smoke by the movable smoke detection device 1, the amount of smoke detected may be notified to the operator by voice (for example, the smoke detection device main body 5 An audio output unit may be provided to change the volume of the signal sound according to the amount of detection of smoke and output it, and the operator may be notified accordingly.
