Alternatively, since the wireless sensor performs an interlocking operation with other wireless sensors, the interlocking signal is wirelessly connected to the other sensors directly or indirectly via the wireless repeater. Is transmitted (for example, refer to Patent Document 1).

  In order to construct a sensing system using such a wireless sensor, various signals such as a transmission signal and an interlock signal transmitted from the wireless sensor are normally received by a wireless repeater or the like. Thus, it is necessary to determine the arrangement of these wireless sensors and wireless repeaters. However, since the signal strength and reception distance of the signal are affected by the structure and materials of the building and various obstacles, a wireless sensor or a wireless repeater is actually installed in the building where the sensing system is actually built. After placement, it was necessary to perform a communication test to confirm whether or not the signal transmitted from the wireless sensor was correctly received by the wireless repeater or the like.

  In such a conventional communication test, specifically, a plurality of workers went to the building, and one worker placed a wireless sensor at a planned installation position (for example, a specific position on the ceiling surface). In this state, the inspection switch for starting the inspection process provided in the wireless sensor is operated, and the other operator displays an indicator light such as a wireless relay arranged at a position away from the wireless sensor. The signal transmitted by the inspection process from the wireless sensor was confirmed by the wireless repeater or the like.

  Embodiments of a wireless sensor test method and a test jig according to the present invention will be described below in detail with reference to the accompanying drawings. However, the present invention is not limited by these embodiments.

[Embodiment 1]
First, the first embodiment will be described. In this form, the intensity of the signal transmitted from the wireless sensor and received by the receiving jig is measured by looking at the display on the receiving jig.

(Overview of sensing system and test method)
First, an outline of a sensing system and a test method according to the present embodiment will be described. The sensing system includes at least one wireless sensor (hereinafter simply referred to as a sensor) 1 and a receiving device (not shown) that receives a signal transmitted from the sensor 1. As a receiving device, a wireless repeater or a receiver is applicable. As a wireless repeater, there are one that transmits the signal received wirelessly from the sensor 1 to the receiver by wire, and one that wirelessly retransmits the signal received wirelessly from the sensor 1 (repeater). Can be mentioned. Alternatively, the sensing system can be configured such that a plurality of sensors 1 can communicate with each other wirelessly, and in this case, each sensor 1 also functions as a receiving device. Below, the case where the communication test in the case of receiving the signal transmitted from the sensor 1 with a wireless repeater is demonstrated.

  FIG. 1 is an explanatory diagram for explaining a test situation of the sensor 1 according to the present embodiment. Here, description will be made on the assumption that the sensor 1 is installed at any of a plurality of planned installation positions (hereinafter, transmission-side planned positions P1 to P3) set on the ceiling surface of the monitoring area. However, the transmission-side scheduled positions P1 to P3 do not necessarily need to be set in advance before the test, and can be set or changed each time according to the test result. In addition, here, description will be made on the assumption that a receiving device such as a wireless repeater is installed at a planned installation position (hereinafter referred to as a scheduled reception side position P4) away from the planned transmission side positions P1 to P3. In particular, here, a description will be given of a case where a reception-side planned position is set inside a storage box 2 fixed to a wall surface or the like (when a wireless repeater is stored inside the storage box 2).

  The storage box 2 includes a storage box (hereinafter referred to as a transmission-type storage box 2) made of a radio wave transmitting material (resin, glass, wood, etc.) and a radio wave opaque material (metal, etc.). There are storage boxes (hereinafter referred to as impervious storage boxes 2, for example, metal equipment storage boxes and fire hydrant boxes), and different test methods are adopted depending on which storage box 2 is used. In the following, the test method employed when using the transmissive storage box 2 is referred to as “transparent test method”, and the test method employed when using the non-transmissive storage box 2 is referred to as “non-transmissive test”. It is referred to as “method”. However, when there is no need to distinguish between the transmission-type storage box 2 and the non-transmission-type storage box 2, these are simply referred to as “storage box 2”, and the transmission-type test method and the non-transmission-type test method Are not collectively distinguished from each other, they are simply collectively referred to as “test methods”.

  In this test method, the operator roughly arranges the sensor 1 using the transmission side jig 3 at the transmission side predetermined position P1. On the other hand, the worker places the receiving side jig 4 at the receiving side scheduled position P4. Then, when the operator transmits a signal to the sensor 1, this signal is received by the receiving jig 4, and the intensity of the received signal is measured by the receiving jig 4, and the measured intensity Is displayed. Then, by reading this intensity by the operator, the received signal intensity when the sensor 1 is arranged at the transmission-side planned position P1 can be confirmed. Next, the operator arranges the sensor 1 at the other transmission side planned position P2 using the transmission side jig 3, causes the sensor 1 to transmit a signal, and the operator displays the signal on the reception side jig 4. By reading the measured intensity, it is possible to confirm the signal intensity when the sensor 1 is arranged at the transmission side predetermined position P2. Similarly, the signal is transmitted every time the sensor 1 is arranged at different transmission-side planned positions P1 to P3, and the intensity displayed on the reception-side jig 4 is read each time the signal is transmitted, and the signal intensity is the best. The communication test is terminated by specifying the transmission-side planned positions P1 to P3. And the sensor 1 can be fixed to the transmission side predetermined positions P1-P3 with the best signal strength specified by this communication test.

  In this test method, as the sensor 1, the actually installed sensor 1 may be used, or the test sensor 1 may be used. However, even if the test sensor 1 is used, a sensor that can transmit the same signal as that of the actually installed sensor 1 is used. On the other hand, it is not necessary to actually use the wireless repeater, and the receiving side jig 4 is used instead of the wireless repeater.

(Transmission side jig)
Next, the configuration of the transmission side jig 3 will be described. FIG. 2 is a side view of the transmission side jig 3, and FIG. 3 is a side view of the sensor 1 housed in the housing portion 30 of the transmission side jig 3. The transmission side jig 3 is a test jig for testing the sensor 1 and can be operated in a state where the sensor 1 can be accommodated. Specifically, the transmission-side jig 3 is configured to include a housing part 30 and a support bar 31.

  The accommodating part 30 is an accommodating means for accommodating the sensor 1, and includes an accommodating part main body 30a and a fixing part 30b. The housing portion main body 30a is a bowl-shaped hollow body having an internal space in which the sensor 1 can be housed, and the upper surface in FIG. 2 is an opening surface. The sensor 1 can be taken in and out. An insertion hole 30c for inserting a later-described inspection string 11b of the sensor 1 is formed in the housing main body 30a. Moreover, the fixing | fixed part 30b closes the opening surface of the accommodating part main body 30a so that opening and closing is possible, is a plate-shaped body, and is being rotatably fixed to the accommodating part main body 30a. Then, in a state where the sensor 1 is fixed to the surface of the fixing portion 30b on the side of the accommodating portion main body 30a with a screw or the like, the sensor 1 is closed by the fixing portion 30b by closing the opening surface of the accommodating portion main body 30a. Placed inside. Here, the housing part main body 30a and the fixing part 30b are made of a radio wave transmitting material, and a signal transmitted from the sensor 1 is transmitted through the housing part main body 30a and the fixing part 30b to the outside. Is done. Further, the storage unit main body 30a and the fixing unit 30b are formed of a transparent or translucent material (transparent or translucent resin, glass, etc.), and the state of the sensor 1 disposed inside the storage unit main body 30a. Can be visually observed from the outside.

  The support rod 31 is a support means for supporting the accommodating portion 30 and is formed as an elongated rod-like body. The accommodation portion 30 is fixed to one end (the upper end in FIG. 2) of the support rod 31 with a screw or the like (not shown). In addition, a holding portion 31a for holding the support rod 31 by an operator is provided at the other end of the support rod 31 (lower end in FIG. 2). The support bar 31 is formed with a length from the operator's trunk to the ceiling surface so that the sensor 1 accommodated in the accommodation unit 30 can be disposed in the vicinity of the ceiling surface. The support bar 31 is made of a radio wave transmitting material in order to prevent the propagation of the radio wave transmitted from the sensor 1 from being affected.

(sensor)
Next, the configuration of the sensor 1 will be described. FIG. 4 is a block diagram showing an electrical configuration of the sensor 1. This detector 1 is configured as a smoke detector (scattered light type) fire detector, and is configured in the same manner as a conventional smoke detector (scattered light type) fire detector unless otherwise specified. ing. Specifically, as shown in FIGS. 3 and 4, the sensor 1 is configured by housing a sensor body 11 inside a sensor cover 10. The sensor body 11 includes a smoke detector 12 having a light emitting unit 13 and a light receiving unit 14, a control unit 15, and a storage unit 16. When no smoke is present in the smoke detector 12, the light emitted from the light emitter 13 is not received by the light receiver 14, and when smoke is present in the smoke detector 12, the light emitter 13 The emitted light is scattered by the smoke particles and received by the light receiving unit 14. The control unit 15 calculates the smoke concentration based on the amount of light received by the light receiving unit 14, and if the smoke concentration is equal to or higher than a certain concentration, the control unit 15 determines that a fire has occurred. (Detection signal) is transmitted wirelessly. The storage unit 16 stores a sensor ID for uniquely identifying the sensor 1. The control unit 15 also includes an electric circuit for generating a radio signal.

  Further, as shown in FIG. 4, the sensor 1 is provided with an antenna 17, an indicator lamp 18, and a battery 19. The antenna 17 is a transmission means for performing wireless transmission, and the transfer signal is wirelessly transmitted through the antenna 17. The indicator lamp 18 is an output means for notifying the occurrence of a fire and the like, and is provided so as to be exposed to the outside from the sensor cover 10, and blinks when it is determined that a fire has occurred. The battery 19 is a power supply means, and power is supplied from the battery 19 to each part of the sensor 1.

  As a signal transmitted from the sensor 1 configured as described above, in addition to the above-described transmission signal, there is a voltage decrease signal transmitted when the voltage of the battery 19 decreases below a predetermined voltage. The transmission of the transfer signal and the voltage drop signal is selected from a plurality of predetermined frequencies (here, two frequencies of one channel and two channels) by a switch (not shown) provided in the sensor 1. Done at two frequencies. In addition, the sensor ID stored in the storage unit 16 is included in the transfer signal and the voltage drop signal.

  As the sensor 1 configured as described above, two types of sensors 1 are prepared: a transmission continuation type sensor 1 and a transmission sequential type sensor 1. The transmission-continuous type sensor 1 is a dedicated sensor configured for testing the sensor 1, and is a sensor that continuously transmits a transmission signal when operated in a predetermined method. . Although this operation method is arbitrary, for example, the sensor main body 11 is provided with a magnetic sensor (not shown), and whenever the magnet is brought close to the sensor 1 from the outside, the magnetic force of the magnet is detected by the magnetic sensor. Thus, the state of the sensor 1 is alternately switched between a sleep state (a state in which the battery 19 is saved without transmitting a transmission signal) and a transmission state (a state in which the transmission signal is transmitted). In the transmission state, for example, the transmission signal is continuously transmitted for 2 seconds and then paused for 2 seconds. Similarly, the transmission and the pause are switched every 2 seconds until the pause state is reached. Unlike the transmission sequential type sensor 1, this sensor 1 outputs a transfer signal regardless of the inspection process, so that the inspection switch 11a and the inspection string 11b described later are unnecessary. This transmission-continuous type sensor 1 is used in a transmission type test method.

  On the other hand, the transmission sequential type sensor 1 is a general-purpose sensor configured for ordinary fire monitoring, and a test is performed using an inspection function provided in the sensor 1 conventionally. . 3 shows the transmission sequential type sensor 1 in a state of being accommodated in the accommodating portion 30, and an inspection switch for starting an inspection process is provided on the bottom surface (upper surface in FIG. 3) of the sensor 1. 11a is provided, and when the inspection switch 11a is turned on, the control unit 15 of the sensor body 11 executes a predetermined inspection process. Sends a report signal by radio. The sensor 1 is provided with an inspection string 11b. The inspection string 11b is for operating the inspection switch 11a at a position away from the sensor 1, one end of which is fixed to the bottom surface of the sensor 1, and the other end of which is the transmission side jig 3. It is pulled out to the outside of the housing part 30 through an insertion hole 30 c provided in the housing part 30, and hangs down in the vicinity of the center position in the longitudinal direction of the support bar 31. Here, since a part of the inspection string 11b is suspended from the inspection switch 11a, the inspection switch 11a can be turned on via the inspection string 11b by pulling the other end of the inspection string 11b downward in the figure. it can. The transmission sequential type sensor 1 is used in an opaque test method.

(Receiving side jig)

When the sensor 1 has been registered with respect to the reception side jig 4, the device registration lamp 42 is lit and received. When the sensor 1 is not registered with the side jig 4, the light is turned off. When the sensor 1 is being registered with the reception side jig 4, the sensor 1 is in a predetermined state (hereinafter referred to as registration waiting state). Will flash.

  The signal intensity indicator lamps 43 a to 43 m are output means for outputting the intensity of the signal received from the sensor 1. Here, a plurality of (in this case, 13) signal intensity indicator lamps 43a to 43m are provided, and a predetermined color (here, the three signal intensity indicator lamps 43a to 43c are red, and the four signal intensities are provided. The indicator lights 43d to 43g emit orange light, the three signal intensity indicator lights 43h to 43j emit yellow light, and the three signal intensity indicator lights green light 43k to 43m). FIG. 7 shows a display method based on the intensity of the signal received from the sensor 1. When the signal strength (in practice, received power, the same applies hereinafter) is −106 dBm or less, it is determined that the signal strength is less than a predetermined signal strength, and none of the signal strength indicator lamps 43a to 43m is lit. . When the signal intensity is −105 dBm or more and −103 dBm or less, it is determined that the signal intensity = D, and the red signal intensity indicator lamp 43a is turned on.

Here, the channel selection switch 44, the registration switch 45, and the reset switch 46 are used as push buttons. The peak hold switch 47 is configured as a dip switch.

  The antenna terminal 48 is a connection terminal for connecting an external antenna (not shown) to the reception-side jig 4 when performing the non-transmission type test method. In other words, the non-transmission type test method is a test method performed assuming that the reception device is accommodated in the non-transmission type storage box 2. In this case, the reception device is accommodated in the non-transmission type storage box 2. The external antenna provided on the outside of the opaque housing 2 is connected to the receiving device by a coaxial cable or the like, and a signal from the outside of the opaque housing 2 is received by the receiving device via the external antenna. It is envisaged that Therefore, in order to perform the non-transmission type test method in a state in which such a reception environment is reproduced, the external antenna is also connected to the reception-side jig 4 accommodated in the non-transmission type storage box 2 for this connection. The antenna terminal 48 is used. The specific configuration of the external antenna is arbitrary. For example, when the non-transmissive housing box 2 is a fire hydrant housing box, the external antenna is placed inside the resin cover of the indicator lamp provided in the fire hydrant housing box. An antenna is arranged.

  In FIG. 6, an antenna 49 is a receiving unit that receives a signal transmitted from the sensor 1. The battery 50 is a power source that supplies power to each part of the receiving jig 4.

It is assumed that the operation without control is executed by the control unit 52. In this test method, basically, it is assumed that two workers perform the test, and the worker who operates the transmission side jig 3 and the sensor 1 is designated as the transmission side worker and the reception side treatment. Workers who operate the tool 4 are referred to as receiving workers.

(Test method-Transmission type test method-Channel selection process)
First, the transmission type test method will be described. First, a channel selection process is performed (SA1). This channel selection step is a step of selecting a channel for receiving a signal from the sensor 1. Specifically, when the reception side worker presses the channel selection switch 44 of the reception side jig 4, the control unit 52 of the reception side jig 4 selects the channel selected at that time (at the time of the first operation, the factory shipment The channel selected at the time) is acquired from the storage unit 51, and the signal intensity indicator lamps 43a to 43m corresponding to the acquired channel (when the A channel is selected, the signal intensity indicator lamp 43m and the B channel are selected). If it is, the signal strength indicator lamp 431) is turned on to notify the receiving side operator of the selected channel. When it is necessary to change the channel, if the reception side operator presses the channel selection switch 44 again while the signal strength indicator lamps 43m and 43l are lit, the control unit 52 of the reception side jig 4 selects at that time. A new channel is stored in the storage unit 51, and the signal intensity indicator lamps 43m and 43l corresponding to the newly stored channel are turned on to receive the channel change. Notify the side worker. This completes the channel selection process.

(Test method-Transmission test method-Sensor registration process)
Next, a sensor registration process is performed (SA2). This sensor registration process is a process of registering the sensor 1 to be tested in the reception side jig 4 so that only the intensity of the signal transmitted from the registered sensor 1 is displayed on the reception side jig 4. is there. Specifically, when the reception-side worker operates the registration switch 45 of the reception-side jig 4 by a predetermined method (for example, by pressing and holding for 1 second or longer), the control unit 52 of the reception-side jig 4 The tool 4 is put into the registration waiting state and the device registration lamp 42 is blinked to notify the receiving side worker that the receiving side jig 4 is put into the registration waiting state.

  In this registration waiting state, if the transmission side operator operates the inspection switch 11a of the sensor 1 to be tested within a range where the signal reliably reaches the reception side jig 4, the control unit 15 of the sensor 1 The inspection process is executed, and a signal including its own sensor ID is transmitted. When the control unit 52 of the receiving side jig 4 receives the signal transmitted from the sensor 1 in the channel selected in the channel selection step, the control unit 52 acquires the sensor ID from the signal, and acquires the acquired sensor ID. The sensor ID of the sensor 1 to be tested is stored in its own storage unit 51, the registration waiting state of the reception jig 4 is terminated, and the device registration lamp 42 is turned on, whereby the reception jig 4, the receiver 1 is informed that the sensor 1 has been registered. This completes the sensor registration process.

  In addition, when changing the registered sensor 1 to another sensor 1 after performing registration in this way, the receiving side operator operates the registration switch 45 again in the same manner, so that Similarly, other sensors 1 can be registered. Further, when the receiving side operator 4 operates the registration switch 45 by a predetermined method (for example, long press for 1 second or more) while the receiving side jig 4 is in the registration waiting state, the receiving side jig 4 is at that time. If there is a sensor 1 registered in the, the registered content is deleted. In addition, the receiving side jig | tool 4 displays the intensity | strength of the received signal irrespective of the transmission origin apparatus, when the registration of the sensor 1 is not performed. Therefore, for example, when there is no wireless sensor using the same radio frequency other than the sensor 1 to be tested in the reception area of the receiving side jig 4, this registration operation is omitted and the test is performed. It can be performed.

(Test method-Transmission type test method-Transmitting side arrangement process)
Next, a transmission side arrangement process is performed (SA3). This transmission side arrangement process is a process of arranging the sensor 1 at the planned installation position. Specifically, after the transmission-side worker accommodates the transmission-continuous type sensor 1 in the accommodating part 30 of the transmission-side jig 3, the transmission-side worker holds the support bar 31 and brings the sensor 1 near the ceiling surface. By lifting, the sensor 1 is placed at a predetermined position on the transmission side (for example, P1 in FIG. 1). This completes the transmission side arrangement process.

(Test method-Transmission type test method-Signal transmission process)
Next, a signal transmission process is performed (SA4). This signal transmission step is a step of operating the sensor 1 to transmit a signal from the sensor 1. Specifically, the transmission-side worker sets the sensor 1 in a transmission state by operating the transmission-continuous sensor 1 by a predetermined method. For example, when the transmission state is set by bringing a magnet close to the sensor 1, the fixing portion 30b is set after the magnet is moved close to the sensor 1 fixed to the fixing portion 30b of the transmission side jig 3. Thus, the housing main body 30a is closed, and the sensor 1 is lifted near the ceiling surface. Alternatively, when the magnetic force of the magnet reaches the sensor 1 via the housing part 30, the housing part main body 30a is closed by the fixing part 30b, and then the magnet is brought close to the sensor 1 to be in a transmission state. 1 may be lifted near the ceiling surface. This completes the signal transmission process. Thus, either the transmission side arrangement step and the signal transmission step may be performed first or may be mixed with each other.

(Test method-Transmission type test method-Receiving side arrangement process)
Next, a receiving side arrangement process is performed (SA5). In this receiving side arrangement process, the receiving side jig 4 that receives the signal transmitted from the sensor 1 and displays the intensity of the received signal is installed, and the receiving device that receives the signal transmitted from the sensor 1 is installed. It is a process of arranging at a planned position. Specifically, the reception-side worker arranges the reception-side jig 4 inside the transmission type storage box 2. At this time, the reception-side worker turns off the peak hold switch 47 of the reception-side jig 4 so that the signal intensity indicator lamps 43a to 43m of the reception-side jig 4 can be seen from the outside of the transmissive container 2 ( For example, it is assumed that the door of the transmission container 2 is left open). The reason why the signal intensity indicator lamps 43a to 43m of the receiving side jig 4 are visible from the outside of the transmission type storage box 2 is that the transmission type storage box 2 transmits signals. Since the same result can be obtained when the test is performed with the receiving-side jig 4 sealed inside, and when the test is performed with a part of the transmission-type storage box 2 opened, the transmission-type storage By performing a test with a part of the box 2 opened (in a state where the signal intensity indicator lamps 43a to 43m are visible from the outside of the transmissive storage box 2), the signal intensity indicator lamps 43a to 43m can be easily confirmed. This is to increase the test work efficiency. This completes the receiving side arrangement process. This reception side arrangement step may be performed prior to the transmission side arrangement step and the signal transmission step, or may be performed simultaneously with the transmission side arrangement step and the signal transmission step.

(Test method-Transmission type test method-Signal strength measurement process)
Next, a signal intensity measurement step is performed (SA6). This signal strength measuring step measures the intensity of the signal displayed on the receiving side jig 4 after the transmitting side arranging step, the receiving side arranging step, and the signal transmitting step, and thereby a sensor based on the strength. This is a step that makes it possible to determine the test result of 1. Specifically, the signal from the sensor 1 arranged in the transmission side arrangement step and transmitted in the signal transmission step passes through the transmission type accommodation box 2 and reaches the reception side jig 4, and passes through the antenna 49. Is received by the receiving jig 4. The control unit 52 of the receiving side jig 4 determines whether or not the sensor ID included in the signal matches the sensor ID stored in its own storage unit 51, and if it matches, the signal intensity is measured. The unit 52a measures the intensity of the signal and turns on the signal intensity indicator lamps 43a to 43m according to the measured intensity. On the other hand, if they match, no processing is performed. This signal is transmitted from the sensor 1 every 2 seconds, and its intensity may change depending on various conditions. When the intensity changes in this way, each time, the signal depends only on the latest intensity. The intensity indicator lamps 43a to 43m are turned on (here, since the peak hold switch 47 is turned off in the receiving side arrangement step, peak hold is not performed). Then, the reception side worker reads this intensity to determine the test result of the sensor 1 (confirms the signal intensity when the sensor 1 is arranged at the transmission side predetermined position P1). This completes the signal strength measurement process.

  Thereafter, the transmission side worker performs a second transmission side arrangement process (SA7), and arranges the sensor 1 at a transmission side scheduled position (for example, P2 in FIG. 1) different from the first transmission side arrangement process. In this case, the sensor 1 can be easily and quickly moved by moving the support bar 31 while the sensor 1 is housed in the container. Thereafter, a second signal strength measurement step is performed (SA8), and the signal strength when the sensor 1 is arranged at the second transmission side predetermined position is confirmed. Thereafter, similarly, the transmission side arrangement step and the signal intensity measurement step are arranged, and in the transmission side arrangement step, the sensor 1 is arranged at a predetermined transmission side position (for example, P3 in FIG. 1) different from the previous transmission side arrangement step. On the other hand, the signal strength when the sensor 1 is arranged at each scheduled position on the transmission side is sequentially confirmed by repeating alternately (not shown in FIG. 8). Then, based on the signal intensity at each confirmed transmission-side planned position, whether or not the installation environment of the sensor 1 is appropriate (whether a signal intensity equal to or higher than a predetermined signal intensity is obtained) and the most preferable installation of the sensor 1 The position (installation position with the highest signal intensity) is determined, and the transmission test method is completed.

(Test method-Impervious test method-Sensor registration process, channel selection process, transmission side arrangement process)
Next, the opaque test method will be described. First, the channel selection process (SA1), the sensor registration process (SA2), and the transmission side arrangement process (SA3) are performed in the same manner as in the transmission test method. However, in the transmission side arrangement process, the transmission sequential type sensor 1 is accommodated in the accommodating portion 30 of the transmission side jig 3, and the other end of the inspection string 11b of the sensor 1 is accommodated through the insertion hole 30c. It is pulled out to the outside of the part 30 and is in a state of being hung down in the vicinity of the center position in the longitudinal direction of the support bar 31. The peak hold switch 47 of the sensor 1 is turned on.

(Test method-Impervious test method-Signal transmission process)
Next, a signal transmission process is performed (SA4). Specifically, the transmission-side worker pulls the other end of the inspection string 11b of the sensor 1, thereby turning on the inspection switch 11a via the inspection string 11b and causing the sensor 1 to start an inspection process. In this inspection process, the control unit 15 of the sensor 1 intermittently transmits a transfer signal for a predetermined time (for example, 30 seconds). The reason why intermittent transmission is performed in this way is that it is necessary to provide a downtime due to restrictions of the Radio Law.

(Test method-Impervious test method-Receiving side arrangement process)
Next, a receiving side arrangement process is performed (SA5). Specifically, the reception-side worker arranges the reception-side jig 4 inside the impermeable storage box 2. At this time, the reception-side worker completely accommodates the reception-side jig 4 inside the non-transparent accommodation box 2. The reason why the receiving side jig 4 is completely accommodated in the non-transmission type storage box 2 is that the non-transmission type storage box 2 does not transmit a signal, so Since the result may be different between the case where the test is performed with the tool 4 sealed and the case where the test is performed with a part of the impermeable container 2 opened, a part of the impermeable container 2 is This is because the test is performed accurately by performing the test in a state in which the signal strength indicator lamps 43a to 43m are not visible from the outside of the non-transparent type storage box 2 without being opened. However, an external antenna is connected to the antenna terminal 48 of the reception side jig 4 so that the reception side jig 4 can receive signals. This completes the receiving side arrangement process. This reception side arrangement step may be performed before the transmission side arrangement step, or may be performed simultaneously with the transmission side arrangement step, but needs to be performed before the signal transmission step.

(Test method-Impermeability test method-Signal strength measurement process)
Next, a signal intensity measurement step is performed (SA6). Specifically, the signal from the sensor 1 arranged in the transmission side arrangement step and transmitted in the signal transmission step is received by the reception side jig 4 via the external antenna. The control unit 52 of the reception side jig 4 performs only when the sensor ID included in the signal matches the sensor ID stored in the storage unit 51, as in the case of the signal strength measurement step of the transmission test method. The intensity of the signal is measured, and the signal intensity indicator lamps 43a to 43m are turned on according to the measured intensity. This signal is continuously transmitted from the sensor 1 for 30 seconds, but its intensity may change depending on various conditions. Here, since the peak hold switch 47 is turned on, the maximum signal strength specifying unit 52b always specifies the maximum strength among the signal strengths measured by the signal strength measuring unit 52a. The signal intensity indicator lamps 43a to 43m are turned on so that the specified maximum intensity is displayed. For example, when the intensity of the signal measured by the signal intensity measuring unit 52a changes from −99 dBm to −81 dBm and further changes to −105 dBm, the signal intensity indicator corresponding to the maximum intensity of −81 dBm. 43i is lit. Then, after the transmission of the signal from the sensor 1 is completed, the reception side worker takes out the reception side jig 4 from the non-transparent type storage box 2 and displays the maximum displayed on the signal intensity display lamps 43a to 43m. By reading the intensity, the signal intensity when the sensor 1 is arranged at the planned position on the transmission side is confirmed. This completes the signal strength measurement process.

  After that, the transmission side worker performs the second transmission side arrangement process (SA7), and after arranging the sensor 1 at a transmission side planned position (for example, P2 in FIG. 1) different from the first transmission side arrangement process, A second signal transmission step is performed (SA8). Further, the reception-side worker performs the second reception-side arrangement step (illustration of steps after the second reception-side arrangement step in FIG. 8 is omitted). At this time, the reception side operator resets the maximum intensity display by the signal intensity indicator lamps 43a to 43m by operating the reset switch 46 by a predetermined method (for example, long pressing for 1 second or more). The jig 4 is housed again in the impermeable container 2. Thereafter, a second signal strength measurement step is performed to check the signal strength when the sensor 1 is arranged at the second transmission side scheduled position. Thereafter, similarly, the transmitting side arranging step, the receiving side arranging step, and the signal intensity measuring step are performed in such a manner that the sensor 1 is placed in the transmitting side arranging step different from the previous transmitting side arranging step (for example, in FIG. The signal intensity when the sensor 1 is arranged at each scheduled position on the transmission side is sequentially confirmed by repeating the process sequentially while arranging in P3). Then, based on the signal intensity at each confirmed transmission-side planned position, whether or not the installation environment of the sensor 1 is appropriate (whether a signal intensity equal to or higher than a predetermined signal intensity is obtained) and the most preferable installation of the sensor 1 The position (installation position with the highest signal intensity) is determined, and the non-transmissive test method is completed.

(effect)
As described above, according to the first embodiment, the sensor 1 is disposed so as to be movable with respect to the transmission-side planned position, and the reception-side jig 4 is disposed at the reception-side planned position of the receiving device. By measuring the intensity of the signal displayed in 4, the test result of the sensor 1 can be determined based on the intensity, so that the sensor 1 is actually fixed to the scheduled position on the transmission side. It is possible to perform the test without any problem, and the test work efficiency can be improved. In addition, when the sensor 1 is actually fixed to the planned position on the transmission side, it may be necessary to fix the sensor 1 by a method of damaging the ceiling surface, such as screwing. By using the fixing method, the test can be performed without damaging the ceiling surface. In addition, the sensor 1 can be fixed at a height at which the ceiling is to be stretched even in the middle of construction where the ceiling is not yet stretched, and the test can be performed before the ceiling is stretched. .

  Further, when performing a communication test on the assumption that a receiving device is installed in a transmissive container 2 made of a radio wave transmitting material, the signal intensity indication from the outside of the container is displayed on the receiving side jig 4. By conducting the test so that it can be seen, the intensity of the signal can be measured without taking out the receiving jig 4 from the transmissive container 2, and the sensor 1 is sequentially moved to a plurality of predetermined positions on the transmitting side. Since the signal strength can be easily measured each time the movement is performed, the test work efficiency can be improved.

  Further, when performing a communication test on the assumption that a receiving device is installed in the non-transmissive container 2 made of radio wave opaque material, the receiving side jig 4 is provided so that the installation environment of the receiving device can be reproduced. Even when it is completely housed in the non-transmissive container 2, after the signal is transmitted from the sensor 1 to the receiver jig 4, the receiver jig 4 is taken out from the non-transmissive container 2 and the reception is performed. Since the maximum intensity recorded by the side jig 4 can be specified, an accurate communication test can be performed.

  In addition, since a plurality of signal intensity indicator lamps 43a to 43m that are turned on or blinking according to the intensity of the signal measured by the signal intensity measuring unit 52a are provided, by visually observing the plurality of signal intensity indicator lamps 43a to 43m. It becomes possible to grasp the intensity of the signal easily and quickly, and the test work efficiency can be further enhanced.

  Further, after the sensor 1 is accommodated in the accommodating portion 30, it can be easily arranged at the planned arrangement position by the support rod 31, and the test is performed without actually fixing the sensor 1 to the planned position on the transmission side. It is possible to increase the test work efficiency.

[Embodiment 2]
Next, a second embodiment will be described. In this form, a signal indicating the intensity of the signal received by the receiving side jig is wirelessly transmitted. However, the configuration in the second embodiment is the same as the configuration in the first embodiment except for a portion to be specially described, and description thereof is omitted by adding the reference numerals used in the first embodiment as necessary. To do.

(sensor)
First, the configuration of the sensor 6 according to the second embodiment will be described. FIG. 9 is a block diagram showing an electrical configuration of the sensor 6. The sensor 6 includes a control unit 60. The control unit 60 is configured in substantially the same manner as the control unit 15 of the sensor 1 in the first embodiment, but differs in that a maximum intensity notification unit 60a is provided. Based on the signal transmitted from the reception side jig 4, the maximum intensity notification unit 60a informs the transmission side worker of the maximum intensity of the signal transmitted from the sensor 6 and measured by the reception side jig 4. It is a maximum intensity notification means for notification.

  As a specific method of this notification, it is preferable to use an existing output means provided in the sensor 6, for example, through a speaker (not shown) for outputting a fire alarm sound. A predetermined voice message corresponding to the maximum intensity (for example, “the maximum intensity is −90 dBm”) may be output, or an indicator lamp 18 for performing a fire alarm display is determined according to the maximum intensity of the signal. You can also use flashing or lighting with the method. In the following, the case where the indicator lamp 18 is blinked by a predetermined method corresponding to the maximum intensity of the signal will be described. Specifically, the number of indicator lamps 18 corresponding to the signal intensity level shown in FIG. Flash once at a predetermined interval for level 1 and 13 times for level 13).

  As the sensor 6, similarly to the first embodiment, a transmission continuation type sensor may be used in the transmission type test method, and a transmission sequential type sensor may be used in the non-transmission type test method. However, in this embodiment, in any of the test methods, a transmission continuation type sensor can be used, and the use of the transmission continuation type sensor can improve the test work efficiency. Since this is possible, the description will be made on the assumption that a transmission continuation type sensor is used.

(Receiving side jig)
Next, the configuration of the receiving side jig 7 according to the second embodiment will be described. FIG. 10 is a block diagram showing an electrical configuration of the receiving side jig 7. The receiving side jig 7 includes a control unit 70. The control unit 70 is configured in substantially the same manner as the control unit 52 of the reception side jig 4 in the first embodiment, but differs in that a maximum intensity transmission unit 70a is provided. The maximum intensity transmitting unit 70 a is a transmitting unit that wirelessly transmits a signal indicating the maximum intensity of a signal transmitted from the sensor 6 and received by the receiving-side jig 7. This signal is performed on the channel set by using the channel selection switch 44.

(Test method)
Next, a test method performed using the transmission side jig 3, the sensor 6, and the reception side jig 7 will be described. Here, unlike the first embodiment, a case where one worker performs a test will be described. However, unless otherwise explained, the explanation can be made by assuming that the reception side worker and the transmission side worker of the first embodiment are also combined with one worker, and thus repeated explanation is omitted.

(Test method)
Next, the test method will be described. In the present embodiment, the transmission type test method and the non-transmission type test method can be performed by substantially the same method. Specifically, the operator performs a channel selection process, a sensor registration process, a transmission side arrangement process, a signal transmission process, and a reception side arrangement process in the same manner as in the first embodiment. In this reception side arrangement step, the operator turns off the peak hold switch 47 of the reception side jig 7. In the case of the transmission type test method, the reception-side jig 7 is stored in the transmission-type storage box 2 as in the case of the first embodiment, and the signal intensity indicator lamps 43a to 43m of the reception-side jig 7 are transmitted. Although it may be in a state visible from the outside of the mold storage box 2, the receiving side jig 7 is accommodated in the transmission type storage box 2 in a sealed manner in both the transmission type test method and the non-transmission type test method. Also good.

  Next, a signal intensity measurement process is performed. In this signal intensity measurement process, the control unit of the receiving side jig 7 stores the sensor ID included in the signal transmitted from the sensor 6 in its own storage unit 51, as in the first embodiment. The signal strength measuring unit 52a measures the strength of the signal and turns on the signal strength indicator lamps 43a to 43m according to the measured strength. Let Further, in the present embodiment, the maximum signal strength specifying unit 52b always specifies the maximum strength among the signal strengths measured by the signal strength measuring unit 52a, and the maximum strength transmitting unit 70a A signal indicating the maximum intensity of the received signal is wirelessly transmitted via the antenna 49. At this time, the signal transmitted from the sensor 6 and the signal transmitted from the receiving side jig 7 and received by the sensor 6 have a level of the signal transmitted from the sensor 6 inside the circuit of the sensor 6. It is assumed that the phenomenon becomes so strong that the signal transmitted by the sensor 6 cancels the received signal, and the sensor 6 cannot receive the signal transmitted from the receiving jig 7. . As a countermeasure, the sensor 6 provides a pause time for the transmission time, and during this pause time, a signal indicating the maximum intensity is transmitted from the reception side jig 7 via the antenna 49, or the sensor 6 The radio frequency of the signal transmitted from 6 to the receiving jig 7 and the signal transmitted from the receiving jig 7 to the sensor 6 are different.

  On the other hand, when the signal transmitted from the receiving jig 7 is received via the antenna 17, the maximum intensity notification unit 60 a of the sensor 6 indicates the maximum intensity (sensing) of the signal indicated by the received signal. The indicator lamp 18 is displayed according to the maximum intensity of the signal transmitted from the device 6 and received by the receiving jig 7. Therefore, the operator can confirm the maximum intensity of the signal by looking at the display of the sensor 6 without looking at the receiving jig 7. This completes the signal strength measurement process.

  Thereafter, the transmission side worker performs the second transmission side arrangement process, and after arranging the sensor 6 at a transmission side planned position (for example, P2 in FIG. 1) different from the first transmission side arrangement process, A signal strength measurement process is performed, and the signal strength when the sensor 6 is arranged at the second scheduled position on the transmission side is confirmed. Thereafter, similarly, the transmitting side arranging step and the signal intensity measuring step are arranged, and in the transmitting side arranging step, the sensor 6 is arranged at a predetermined transmitting side position (for example, P3 in FIG. 1) different from the previous transmitting side arranging step. However, the signal strength when the sensor 6 is arranged at each of the transmission-side planned positions P1 to P3 is sequentially confirmed by repeating alternately.

(effect)
As described above, according to the second embodiment, the intensity of the signal transmitted from the sensor 6 and received by the reception side jig 7 can be displayed on the sensor 6, so that only the operator on the transmission side can display it. Since the signal intensity can be easily measured each time the wireless sensor 6 is moved sequentially to a plurality of scheduled positions on the transmission side, the test work efficiency can be further improved.

[Modifications to Embodiment]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can do. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and the present invention solves the problems not described above or has the effects not described above. There are also cases where only some of the described problems are solved or only some of the described effects are achieved.

(About the sending side jig)
The transmission side jig 3 is configured to completely accommodate the sensors 1 and 6 in the accommodating portion 30, but is configured to expose a part of the sensors 1 and 6 from the accommodating portion 30 to the outside. However, since it does not affect the transmission intensity of the signal, the external exposure may be possible. Moreover, you may enable it to operate the inspection switch 11a other than the inspection string 11b. For example, an opening is formed in the fixed portion 30b, only the inspection switch 11a is exposed from the opening to the outside of the fixed portion 30b, and the storage portion 30 is pressed against the ceiling surface from below, so that the inspection switch 11a may be turned on, and in this case, a signal can be transmitted simply by placing the sensors 1 and 6 at the planned placement positions via the support rod 31.

(About sensor)
As the sensors 1 and 6, it has been described that two types of sensors, a transmission continuation type sensor and a transmission sequential type sensor, are prepared. A switching unit may be provided, and the switching unit may be operated to switch between the transmission continuation type sensor and the transmission sequential type sensor as necessary.

(Receiving side jig)
In the second embodiment, it has been described that only the signal indicating the maximum intensity of the signal transmitted from the sensor 6 and received by the receiving jig 7 is transmitted to the sensor 6, but instead of the maximum intensity, Alternatively, in addition to the maximum intensity, a signal indicating the intensity of each signal measured by the receiving side jig 7 may be transmitted to the sensor 6. Further, as a configuration for enabling the transmission side to confirm the intensity of the signal transmitted from the sensor 6 and received by the reception side jig 7, a configuration other than the configuration described in the second embodiment may be adopted. For example, the receiving jig 7 may compare the intensity of the signal transmitted from the sensor 6 with a predetermined threshold value and output a sound corresponding to the comparison result. For example, a continuous buzzer sound is output when the signal intensity is greater than or equal to a predetermined threshold, and an intermittent buzzer sound is output when the signal intensity is less than the predetermined threshold. In this case, it is possible to confirm the intensity of the signal by listening to this sound on the transmission side. Further, the signal intensity output and the maximum intensity output in the receiving side jigs 4 and 7 have been described as being performed by the signal intensity indicator lamps 43a to 43m, but may be performed by other output means. For example, a liquid crystal monitor may be provided to display the intensity numerically, or a speaker may be provided to output the intensity as a sound or a voice message (for example, “maximum intensity is −90 dBm”).

(About workers)
In the first embodiment, it is assumed that two workers perform the test, but it is also possible to perform the test by one worker. For example, in the transmission test method, each step is performed as follows: One worker may sequentially perform while moving as necessary. However, if the signal intensity indicator lamps 43a to 43m of the receiving side jigs 4 and 7 cannot be seen from the planned arrangement positions of the sensors 1 and 6, the receiving side jig 4 is the same as in the non-transmission type test method. , 7 may be turned on so that the signal intensity at the receiving side jigs 4, 7 can be confirmed after the signals are transmitted from the sensors 1, 6.
