When the sensor issues a notification, the notification indicator lights, so the inspector reads the value of the densitometer when the notification indicator lights.

JP-A-4-599

  By the way, when inspecting the smoke detector using the smoke detector test apparatus of Patent Document 1, the inspector reads the value of the densitometer when the alarm indicator lamp is lit, and the value of the densitometer is a predetermined value. When it is within the range, it is determined that the smoke sensor is acceptable, and when the value of the densitometer is outside the predetermined range, it is determined that the smoke sensor is unacceptable. Furthermore, it is necessary to write down the value of the densitometer as necessary. For this reason, there is a problem that the work of the inspector becomes complicated.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a smoke detector test apparatus capable of smoothly performing a pass / fail determination of a plurality of smoke detectors.

  In order to solve the above-described problems and achieve the object, a smoke detector test apparatus according to the present invention includes a storage unit having a test space in which a plurality of smoke detectors to be tested are stored, and the test space. A smoke generating unit for generating simulated smoke, a control unit for determining whether or not the smoke detector senses the pseudo smoke within a predetermined range, and a display unit for displaying a determination result by the control unit And the display section has a determination result display area provided corresponding to the plurality of smoke detectors, and the control section displays the determination result in the determination result display. Display in the area.

  According to the smoke detector test device of the present invention, a light emitting unit is provided in the determination result display area, and the control unit includes the light emitting unit corresponding to the smoke detector that has passed the determination result. The light emitting unit corresponding to the smoke detector that is in a lighting state and the determination result is not acceptable may be in a blinking state or a light-off state.

  According to the smoke detector test apparatus of the present invention, the display unit may be constituted by a liquid crystal panel.

  According to the smoke detector test apparatus of the present invention, the control unit includes number information for identifying the smoke detector that has been notified in response to each smoke detector detecting and reporting pseudo smoke. A storage unit that records and records the concentration detection value in the test space at the time of reporting, and the control unit stores the concentration detection value stored in the storage unit within the predetermined range; It may be determined whether or not.

  According to the smoke detector test apparatus of the present invention, the storage unit may store the determination results of the plurality of smoke detectors.

  According to the smoke detector test device of the present invention, the smoke detector test device may further include an inner lid portion capable of closing the opening for opening the test space.

  According to the present invention, the control unit automatically determines whether the smoke detector is acceptable or not, and the determination result is displayed in the determination result display area. Therefore, since the inspector can instantly confirm the pass / fail judgment results of the plurality of smoke detectors, the smoke detector can be inspected smoothly. In addition, since the automatic determination is performed by the control unit, it is possible to suppress the difference in the determination result by the inspector as compared with the case where the inspector reads the value of the densitometer and makes the pass / fail determination as in the conventional case. Therefore, a more accurate inspection result can be obtained.

  In addition, since the light emission unit is provided in the determination result display area, the inspector recognizes that the smoke detector whose light emission unit is lit is passed, and the light emission unit is in a blinking state or is turned off. It becomes possible to recognize the sensor as failing. In other words, it is possible to instantly recognize whether or not the light is emitted from the light emitting unit.

  In addition, since the display unit is configured by a liquid crystal panel, the determination result display area can be displayed in a liquid crystal display. As a result, arbitrary display is possible. For example, when the smoke detector is acceptable, for example, a character “OK” is displayed. When the smoke detector is not acceptable, for example, a character “NG” is displayed. Can be displayed. That is, the degree of freedom in displaying the determination result is increased.

  In addition, the control unit detects the smoke information detected by each smoke detector and issues the number information for identifying the detected smoke detector and the detected concentration value in the test space when the notification is issued. Therefore, it is not necessary for the inspector to write down the density detection value of each smoke detector. Therefore, it is possible to smoothly shift to the next inspection.

  In addition, since the storage unit can store the determination results of the plurality of smoke detectors, the inspector can check the determination results of the smoke detectors after inspecting all the smoke detectors. Therefore, it is possible to perform the inspection smoothly.

  Moreover, since the middle cover part which can block | close the opening part which open | releases test space is further provided, it becomes possible to set it as the structure which installs a smoke detector in a middle cover part. This makes it possible to test more smoke detectors simultaneously.

The operation display panel 47 is disposed on the front side of the accommodation space P, and includes a display unit 40 on which test results are displayed, and an operation panel 41 capable of inputting information related to the test.

  As shown in FIG. 8, the upper lid portion 50 is rotatably supported by the housing portion 10 by the restriction member 51. That is, the accommodating part 10 and the upper cover part 50 are separate bodies. Further, the first wall portion 11 and the third wall portion 13 are disposed to face each other while intersecting the extending direction of the rotation axis of the upper lid portion 50. Further, the upper lid portion 50 is opened by the regulating member 51 so that an angle α formed on the opening 16 side between the end surface 50a of the upper lid portion 50 and the upper surface 10a of the housing portion 10 is less than 180 ° in a side view. It is configured to rotate as shown by an arrow in FIG. 8 and to be in a closed state (state shown by a one-dot chain line in FIG. 8) in which the upper lid portion 50 is placed on the upper surface of the accommodating portion 10. That is, when carrying the smoke detector test apparatus 1 before or after the inspection, it is possible to make it compact by closing the inner lid portion 20 and closing the upper lid portion 50.

  In addition, the angle α formed on the opening 16 side between the upper lid portion 50 and the accommodating portion 10 is not particularly limited, but is preferably in the range of 105 ° to 120 °. In the present embodiment, the angle α is 110 °. It is.

  As shown in FIG. 8, the operation panel 41 is disposed in the accommodation space P rather than the end surface 50 a of the upper lid portion 50 in a side view. That is, since the operation panel 41 is located inside the end surface 50a of the upper lid portion 50, it is possible to prevent the operation panel 41 from being pushed when the upper lid portion 50 is closed.

  The control unit 42 is electrically connected to the first mounting bases 60a and 60b, the second mounting base 62, and the inner lid mounting bases 21a and 21b via the wiring 43, and operates the operation panel 41. Thereby, it is possible to supply electric power to each attachment base 60a, 60b, 62, 21a, 21b.

  The control unit 42 is connected to the smoke generation unit 30 via the wiring 43, and can operate to operate the operation panel 41 to supply power to the smoke generation unit 30. When electric power is supplied to the smoke generator 30, the smoke generating agent is heated and pseudo smoke is generated.

  The control unit 42 is electrically connected to the fan 70 via the wiring 43, and can operate to operate the operation panel 41 to supply power to the fan 70. The fan 70 is driven to rotate when electric power is supplied.

  As shown in FIG. 1, the wiring 43 extends from the lower portion of the operation panel 41 toward the housing portion 10. When closing the upper lid part 50, the wiring 43 is accommodated in the gap 10 b in the vicinity of the third wall part 13 in the accommodating part 10, so that the wiring 43 is not sandwiched between the upper lid part 50 and the accommodating part 10.

  FIG. 9 shows a block diagram of the smoke detector test apparatus 1 of the present embodiment. The smoke detector test apparatus 1 includes smoke detectors 2A to 2E, a concentration detector 64, a display unit 40, a smoke generator 30, a fan 70, and a controller 42. The control unit 42 includes a reception unit 44, a storage unit 45, and a determination unit 46.

When the smoke detectors 2 </ b> A to 2 </ b> E detect and notify the pseudo smoke, the reception unit 44 receives number information for identifying the smoke detectors 2 </ b> A to 2 </ b> E, and stores the received number information in the storage unit 45. As this number information, a number corresponding to the position of the mounting base may be used. When ID information for individually identifying the smoke detector is obtained, this ID information may be used.
In the number information of the present embodiment, the smoke detector 2A corresponds to the number “1”, the smoke detector 2B corresponds to the number “2”, the smoke detector 2C corresponds to the number “3”, The smoke detector 2D corresponds to the number “4”, and the smoke detector 2E corresponds to the number “5”. That is, the position of the mounting base and the number are associated with each other. As described above, when the smoke detectors 2A to 2E are notified, the number information 1 to 5 for identifying the smoke detectors 2A to 2E is sent to the receiving unit 44.

The storage unit 45 receives the density detection signal from the density detection unit 64. Since the unit of smoke density used for the operation test of the smoke detector is expressed in terms of the light extinction rate per meter, it is more preferable to store the value obtained by converting the density detection signal into the light extinction rate. Hereinafter, unless otherwise specified, it is assumed that the density detection value is converted into a light reduction rate. The storage unit 45 stores the number information 1 to 5 identifying the smoke detectors 2A to 2E sent from the receiving unit 44 and the density detection value sent from the density detection unit 64 in association with each other. Specifically, the density detection value is read as needed from the density detection unit 64 and can be displayed on the display unit 40 as the current density. The control unit 42 writes the current density detection value and the number information for identifying the smoke detectors 2A to 2E that have been reported in association with each other at the timing at which the smoke detectors 2A to 2E have reported, and writes them in the storage unit 45. The density detection value stored in the storage unit 45 and associated with the number information can be displayed on the display unit 40 by the control unit 42.
In addition, the number information and the concentration detection value associated with the number information can be stored in a recording medium or output to the outside of the smoke detector test apparatus 1. The control unit 42 can also store the inspection date, the inspector, and the like in the storage unit 45.

The determination unit 46 compares whether or not the concentration detection value when the smoke detectors 2A to 2E detect and report the pseudo smoke is within the reference range with the determination reference value, and determines the smoke detectors 2A to 2E. It is determined whether or not the sensitivity is normal. That is, the determination unit 46 performs automatic determination.
The determination unit 46 determines that the smoke detectors 2A to 2E are normal when the density detection value is within the determination reference value, and determines that the smoke detectors 2A to 2E are not normal when the density detection value is smaller or larger than the determination reference value. In addition, there are 1 type, 2 types, and 3 types of smoke detectors, and the nominal operating concentrations are 5%, 10%, and 15%, respectively, and the judgment reference value for each type is stored in the storage unit 45. ing.

  Based on the determination result of the determination unit 46, the display unit 40 displays a determination result as to whether or not the smoke detectors 2A to 2E detect pseudo smoke within a predetermined range. As shown in FIG. 10, the display section 40 is provided with a display field 40a for displaying the density detection values of the smoke detectors 2A to 2E corresponding to the numbers. In addition, a pass / fail indicator lamp (light emitting unit) 65 is provided in the position corresponding to each number, that is, in the determination result display area. In the display unit 40, only the display column 40a may be a screen where the display is switched, for example, a liquid crystal display or a segment display, or the entire display unit 40 including a number may be a liquid crystal display or a segment display. .

The pass / fail indicator lamp 65 is normally turned off, but lights when the sensitivity of the smoke detectors 2A to 2E is normal, and blinks when the sensitivity of the smoke detectors 2A to 2E is not normal.
When the density detection value when each smoke detector 2A to 2E is issued is within the reference range, the control unit 42 lights the pass / fail indicator lamp 65. On the other hand, when the density detection values when the smoke detectors 2A to 2E are issued are out of the reference range, the control unit 42 blinks the pass / fail indicator lamp 65. For example, the pass / fail indicator lamp 65 may be a lamp (bulb) or a liquid crystal display.

  When all the smoke detectors 2 </ b> A to 2 </ b> E are notified, the control unit 42 stops the supply of electric power to the mounting bases 60 a, 60 b, 62, 21 a, 21 b, the smoke generation unit 30, and the fan 70.

Next, a method for inspecting a smoke detector using the smoke detector test apparatus 1 will be described with reference to a flowchart shown in FIG.
First, the inspector T removes the five smoke detectors installed on the ceiling or the like in the building. As shown in FIG. 12, the inspector T hangs the shoulder belt 5 on the shoulder so that the sensitivity test apparatus is located in front. As shown in FIG. 1, five smoke detectors are attached to the first attachment bases 60a and 60b, the second attachment base 62, and the inner lid attachment bases 21a and 21b, respectively (step S1). Further, each of the attached smoke detectors inputs using the operation panel 41 of one type, two types, or three types.

  Next, as shown in FIG. 4, when the inspector T closes the inner lid 20, the magnet switch 22 is turned on, and the controller 42 determines that the inner lid 20 has been closed. The inspector T operates the operation panel 41, and the control unit 42 supplies power to each of the mounting bases 60a, 60b, 62, 21a, 21b, the smoke generation unit 30, and the fan 70 (step S2). ). When the smoke generating unit 30 is heated, the water-soluble liquid as a smoke generating agent is vaporized. As shown by an arrow F in FIG. 5, the vaporized pseudo smoke passes along the lower portion of the base 18 toward the first wall portion 11 and rises along the first wall portion 11 by the rotation of the fan 70. The raised pseudo smoke passes through the mesh-shaped rectifying plate 19, a part of the pseudo smoke enters from the smoke intrusion entrance 2a of the smoke detectors 2B, 2C, 2D, and 2E, and the remaining pseudo smoke passes through the gap G. And enters from the smoke inlet 2a of the smoke detector 2A.

  When the smoke detectors 2A to 2E detect pseudo smoke, the smoke detectors 2A to 2E output an alarm signal. At this time, the number information for identifying the smoke detectors 2A to 2E that have been issued is sent to the storage unit 45 via the reception unit 44, and the concentration detection value detected by the concentration detection unit 64 is sent to the storage unit 45. . Then, the number information for identifying the smoke detectors 2A to 2E and the density detection value are associated with each other and stored in the storage unit 45 (step S3).

  Specifically, when the smoke detector 2A outputs a notification signal, the control unit 42 stores the smoke detector signal of the smoke detector 2A and the concentration detection value when the smoke detector 2A has generated a notification. Write to 45. Thereby, the smoke detector 2A, that is, the number “1” and the density detection value 5 are associated with each other and stored in the storage unit 45. The control unit 42 determines whether all five smoke detectors 2A to 2E have been issued (step S4).

  If the control unit 42 determines that all five smoke detectors 2A to 2E have not been issued (NO in step S4), the control unit 42 returns to step S3.

  Subsequently, when the smoke detector 2C outputs a notification signal, number information for identifying the smoke detector 2C and a density detection value when the smoke detector 2C has issued are sent to the storage unit 45. The smoke detector 2C, that is, the number “3” and the density detection value 9 are associated with each other and stored in the storage unit 45.

  Subsequently, when the smoke detector 2B issues a report, the number “2” and the density detection value 11 are associated with each other and stored in the storage unit 45. Subsequently, when the smoke detector 2D issues a report, the number “4” and the density detection value 15 are associated with each other and stored in the storage unit 45. Subsequently, when the smoke detector 2E issues a report, the number “5” and the density detection value 16 are associated with each other and stored in the storage unit 45. In this way, all the five smoke detectors 2A to 2E are notified, and the number information for identifying the notified smoke detectors 2A to 2E corresponds to the concentration detection value detected by the concentration detector 64. Attached and stored in the storage unit 45.

  Next, when the control unit 42 determines that all five smoke detectors 2A to 2E have been issued (YES in step S4), the control unit 42 causes the mounting bases 60a, 60b, 62, 21a, and 21b to be detected. Then, the supply of electric power to the smoke generator 30 and the fan 70 is stopped (step S5).

  Next, the control unit 42 compares the detected density value with the determination reference value sent by the density detector 64 (step S6). For example, one type of reference determination value is set in a range from 3 to 7, two types of reference determination values are set in a range from 6 to 14, and three types of reference determination values are set in a range from 8 to 22. When there are two types of smoke detectors 2A to 2C and three types of smoke detectors 2D and 2E, the control unit 42 detects the concentration detection values of the smoke detectors with numbers “1”, “2”, and “3”. Is determined from 6 to 14, and it is determined whether the density detection values of the smoke detectors with numbers “4” and “5” are from 8 to 22. As a result, it is determined that the sensitivities of the smoke detectors 2B, 2C, 2D, and 2E with the numbers “2”, “3”, “4”, and “5” are normal (pass) (YES in step S6). As shown in FIG. 13, the control unit 42 displays the density detection values corresponding to the numbers 2, 3, 4, and 5 in the display column 40a, and lights the pass / fail indicator lamp 65 (step S7-1).

  On the other hand, since the density detection value of the number “1” is 5, the control unit 42 determines that the sensitivity of the smoke detector 2A is not normal (failed) (NO in step S6), and corresponds to the number 1. The pass / fail indicator lamp 65 is blinked (step S7-2). In addition, the control part 42 may memorize | store the pass / fail determination result of smoke detectors 2A-2E in the memory | storage part 45, and can record it on a recording medium as needed, or can output it outside.

  When the pass / fail result of the smoke detectors 2A to 2E is displayed, the inner lid portion 20 is opened, the smoke detectors 2A to 2E are removed from the mounting bases 60a, 60b, 62, 21a, and 21b, and returned to a predetermined position. Thus, the inspection of the sensitivity of the smoke detectors 2A to 2E is completed.

  According to the present embodiment, the control unit 42 automatically determines whether or not the smoke detectors 2A to 2E are accepted, and the determination results of the smoke detectors 2A to 2E are displayed on the pass / fail indicator lamp 65 provided in the determination result display area. Is done. Therefore, since the inspector can instantly confirm the pass / fail judgment result of the plurality of smoke detectors 2A to 2E, the smoke detectors 2A to 2E can be inspected smoothly. In addition, since the automatic determination is performed by the control unit 42, the difference in the determination result by the inspector can be suppressed as compared with the conventional case where the inspector reads the value of the densitometer and makes a pass / fail determination. . Therefore, a more accurate inspection result can be obtained.

  In addition, since the pass / fail indicator lamp 65 is provided in the determination result display area, the inspector recognizes that the smoke detectors 2A to 2E with the pass / fail indicator lamp 65 in the lighting state are passed, and passes the pass / fail indicator lamp. It becomes possible to recognize that the smoke detectors 2A to 2E with the number 65 in the blinking state or the unlit state are rejected. That is, it is possible to instantly recognize pass / fail by the light emission state of the pass / fail indicator lamp 65.

  Moreover, the display part 40 may be comprised with the liquid crystal panel. In this case, the determination result display area can be displayed on the liquid crystal, and arbitrary display is possible. Therefore, when the smoke detectors 2A to 2E pass, for example, “OK” is displayed in the corresponding determination result display area. When the smoke detectors 2A to 2E are rejected, for example, the character “NG” can be displayed in the determination result display area. That is, the degree of freedom in displaying the determination result is increased.

  In addition, the control unit 42 performs a test when the smoke detectors 2A to 2E detect the pseudo smoke and issue the number information for identifying the detected smoke detectors 2A to 2E in response to the notification. Since it has the memory | storage part 45 which matches and records the density | concentration detection value in the space S, it is not necessary for an inspector to write down the density | concentration detection value of each smoke detector 2A-2E. Therefore, it is possible to smoothly shift to the next inspection.

  Moreover, since the memory | storage part 45 can memorize | store the determination result of several smoke detectors 2A-2E, respectively, after an inspector test | inspects all the smoke detectors 2A-2E, smoke detectors 2A-2E are examined. The determination result can be confirmed. Therefore, it is possible to perform the inspection smoothly.

Note that the first belt mounting portion 3 on the inner lid portion 20 side may not necessarily be disposed on the near side of the second belt mounting portion 4, and the first belt mounting portion 3 may be the second belt mounting. It may not be arranged on the bottom 15 side from the part 4. That is, if the first belt attaching portion 3 is fixed to the first wall portion 11 and the second belt attaching portion 4 is fixed to the third wall portion 13, the inspector T is shouldering the shoulder belt 5. The smoke detectors 2A to 2E can be inspected smoothly.
Although the smoke detector test apparatus 1 is configured to include the inner lid portion 20 and the upper lid portion 50, the inner lid portion 20 is not necessarily provided, but as shown in the present embodiment, the inner lid portion 20 is provided. It is possible to install the smoke detectors 2A to 2E on the inner lid portion 20. Thereby, it becomes possible to test | inspect more smoke detectors 2A-2E simultaneously.

Moreover, although the accommodating part 10 was made into the rectangular shape in planar view, it is not restricted to this, A trapezoid or a polygon more than a pentagon may be sufficient. In the case of a polygon of pentagon or more, the wall portion increases according to the number of sides, but the first belt attaching portion 3 is provided on the first wall portion facing and the second belt attaching portion is provided on the third wall portion. 4 should just be provided.
The smoke detectors 2A to 2E are not particularly limited, and a normal smoke detector or a petit type detector can be inspected.

  In addition, when the concentration detection value when the smoke detectors 2A to 2E are notified is within the reference range, the pass / fail indicator lamp (light emitting unit) 65 is turned on and the smoke detectors 2A to 2E are notified. When the detected density value is outside the reference range, the pass / fail indicator lamp 65 is blinked, but the present invention is not limited to this. For example, the pass / fail indicator lamp 65 may be left at 2 when the detected density value when the smoke detectors 2A to 2E are issued is out of the reference range.

  Moreover, although the display on the display unit 40 is configured to display the determination results of all the smoke detectors 2A to 2E collectively, the determination results of the smoke detectors 2A to 2E may be displayed one by one. In this case, the determination result of a desired smoke detector may be displayed by operating the operation panel 41. In addition, the determination result of the smoke detector may be sequentially displayed at predetermined time intervals in order from the smoke detector 2A.

  When the magnet switch is in the OFF state, that is, when the inner lid portion 20 is not closed, even if the operation panel 41 is operated, the control unit 42 causes the mounting bases 60a, 60b, 62, 21a, and 21b to be smoked. The generator 30 and the fan 70 may be configured not to be supplied with electric power.

Further, in order to associate the smoke detector being inspected with the displayed number, a number may be assigned near the mounting base.
In the above embodiment, the display unit 40 is attached to the upper lid unit 50, but the display unit 40 may be provided in the storage unit 10. For example, the display unit 40 may be provided on the upper part of the inner lid part 20, or the inner lid part 20 may be configured as a double door so that a smoke detector can be attached to the back side of the first inner lid. The display unit 40 may be provided on the inner lid. After the inner lid portion 20 is configured to be about half the length of the above embodiment, a top plate is provided on the upper surface of the test space S where the inner lid portion 20 is not closed, and the display unit 40 is provided thereon. You may do it.

  In addition to the above embodiment, a fixing portion may be provided in the upper lid portion 50 and the accommodating portion 10 and a mechanism for applying a force to the upper lid portion 50 in the opening direction may be provided. For example, a torque hinge that applies a force in the opening direction to the hinge portion between the upper lid portion 50 and the accommodating portion 10 may be employed. By providing such a mechanism, it is possible to prevent unintentional closing of the upper lid portion 50, and smoke detection caused by closing the upper lid portion 50 while the inner lid portion 20 is opened and the smoke detector is attached. It is possible to prevent contact between the container and the upper lid 50. Further, a wall surface may be erected from the back side of the inner lid part to function as a protective plate. The protective plate is in the downward direction when the inner lid portion 20 is closed and is accommodated in the test space S, is in the upward direction when the inner lid portion 20 is opened, and is present on the closing path of the upper lid portion 50. It is possible to prevent contact between the smoke detector and the upper lid 50 that is generated when the upper lid 50 is closed while the sensor is attached.

  The pass / fail table format of each sensor is different, but the concentration display also has a different display format at the time of pass and fail, for example, it lights up when it passes and flashes when it fails. You may make it. Further, the pass / fail indicator lamp may be a two-color indicator lamp, and pass / fail may be determined by color.

At the end of the test, the determination result and the density at the time of determination may be stored, printed, and / or stored in an external storage medium.
The address data of the sensor may be read by communicating with the sensor. At this time, the address data may be displayed on the display unit. Further, the address data of the sensor that has been recently removed from the field sensitivity tester may be displayed. In this way, since the address of the sensor that has been removed after the test is known, the possibility of installation errors can be reduced when the sensor is returned. The address display unit may be provided near the sensor mounting base.
