In this technique, since it was necessary to bring the magnet of the test jig close to the Hall IC of the sensor, for example, a user would visually align or adjust the angle based on a part of the exterior of the sensor (for example, the position of an indicator light, etc.) and a part of the test jig (for example, a mark for alignment, etc.) and then bring the magnet of the test jig close to the Hall IC of the sensor.

[0006] However, the position of the Hall IC in the sensor (for example, the angle relative to the indicator light) may differ for each model due to space restrictions for mounting on the board, and positioning the test jig relative to the sensor may be time-consuming.

[0020] The term "detection means" refers to a means for detecting a magnetic field applied from outside the protection device, and is a concept that includes, for example, a single unit or a plurality of units. Note that "detecting a magnetic field" is a concept that includes, for example, detecting the presence of a magnetic field and detecting a change in a magnetic field.

[0021] The "testing means" refers to a means for testing the protection device based on the state of detection of the magnetic field by the detection means, and is a concept that includes, for example, a means for testing the protection device when the detection means detects a magnetic field above a predetermined level, and also includes a means for selecting at least one type of test from among multiple types of tests based on which of multiple detection means has detected the magnetic field, and for performing the selected at least one type of test.

[0033] [Specific details of the embodiment] Next, the specific contents of the embodiment will be described.

[0034] (Configuration-sensor) First, the configuration of a detector to which the test device according to the present embodiment is applied will be described. FIG. 1 is a side view of a detector according to the embodiment of the present invention when being tested, FIG. 2 is a block diagram showing the detector, and FIG. 3 is a bottom view of the detector attached to a ceiling. In addition, in FIG. 1 and FIG. 3, the Z axis indicates the vertical direction, and the X axis and the Y axis perpendicular to the Z axis indicate the vertical direction. In FIG. 1, a part of the detector 1 is actually hidden by the test jig 22 and cannot be seen, but is drawn with a solid line for convenience. The detector 1 in FIG. 1 is a prevention device, specifically, a disaster prevention device, and is installed on a ceiling, for example, and includes a physical quantity detection unit 11, a magnetic field detection unit 12, an information output unit 13, a recording unit 14, and a control unit 15 in FIG. 2 as an example.

[0035] (Configuration - Sensor - Physical quantity detection part) The physical quantity detection unit 11 in Fig. 2 is a physical quantity detection means for detecting a physical quantity related to an abnormal fire. The specific type and configuration of this physical quantity detection unit 11 are arbitrary, but for example, it can be configured using a smoke detection means for detecting a smoke detection space and the concentration of smoke that has entered the smoke detection space. The smoke detection means can be configured as a light scattering type or a light reducing type using at least a light emitting unit such as an LED and a light receiving unit such as a photodiode that receives light based on the light from the light emitting unit.

[0036] (Configuration - Sensor - Magnetic Field Detection Section) The magnetic field detection unit 12 in Fig. 2 is a magnetic field detection means that detects a magnetic field applied from outside the sensor 1. The specific type and configuration of this magnetic field detection unit 12 are arbitrary, but for example, it can be configured to include a Hall IC 121 in Fig. 3. The "Hall IC" 121 is the detection means described above, and is provided, for example, inside the cover of the sensor 1, and can be configured using a Hall element.

[0037] (Configuration - Sensor - Information output section) The information output unit 13 in Fig. 2 is an information output means that outputs information related to the sensor 1. The specific type and configuration of this information output unit are arbitrary, but for example, it can be configured to include an indicator light 131 in Fig. 3, etc. The indicator light 131 is a light-emitting means that emits light to the outside of the sensor 1, and can be configured using a light source such as an LED.

[0038] (Configuration - Sensor - Recording unit) 2 is a recording means for recording programs and various data necessary for the operation of the sensor 1, and is configured using, for example, a flash memory. However, any recording medium can be used instead of the flash memory.

[0039] (Configuration - Sensor - Control Unit) 2 is a control means for controlling the sensor 1, and specifically, is a computer including a CPU, various programs interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are started on the OS and realize specific functions), and an internal memory such as a RAM for storing the programs and various data. In particular, the control program according to the embodiment is installed in the sensor 1 via any recording medium or network, thereby substantially configuring each part of the control unit 15.

[0040] 2 conceptually includes, for example, a test unit 151. The test unit 151 is a test means for testing the sensor 1 based on the state of detection of the magnetic field by the Hall IC 121. Note that the processing performed by each unit of the control unit 15 will be described later.

[0041] (Configuration - Test Equipment) Next, a configuration of the test device 2 according to the present embodiment will be described. The test device 2 in Fig. 1 is a device that applies a magnetic field to the sensor 1 in order to perform a test, and includes, for example, a support rod 21 and a test jig 22.

[0042] (Configuration-Test Equipment-Support Rod) 1 is a supporting means for supporting a test jig 22. The specific type and configuration of this supporting rod 21 are arbitrary, but it may be configured as, for example, a long rod.

[0043] (Configuration-Test Equipment-Test Jig) 4 and 5 are perspective views of the test jig, FIG. 6 is a bottom view of the test jig, FIG. 7 is a bottom view of the test jig in a state where it is brought close to a detector on the ceiling, and FIG. 8 is a bottom view of the test jig when the rotation position is changed from that in FIG. 7. For convenience of explanation, in FIG. 4 to FIG. 6, a coordinate system similar to the coordinate system in the case where the test jig 22 is brought close to the detector 1 as shown in FIG. 1 is used for explanation. In FIG. 7, only the outer shape of the test jig 22 is shown, and the detailed shape is omitted. In FIG. 8, the test jig 22 in FIG. 7 is shown in a state where it is slightly rotated clockwise with the center of the test jig 22 as a reference.

[0044] Test jig 22 in Fig. 1 is used in proximity to detector 1. The specific type and configuration of test jig 22 are arbitrary, but for example, it is attached to the tip of support rod 21 by any method (for example, a mounting method using a mounting metal fitting), is cylindrical, and is made of a material that transmits a magnetic field, such as resin, and includes mounting hole 221, magnet 222, proximity surface 223, and hollow portion 224 in Fig. 4.

[0045] (Configuration-Test Equipment-Test Jig-Mounting Hole) The mounting holes 221 are mounting means for mounting the magnet 222 to the test jig 22, and for example, as shown in Figures 4 and 5, they are provided on the outer periphery of the test jig 22, and as shown in Figure 6, four mounting holes 221 are provided, and they are provided at positions where the angle formed between the center of the test jig 22 and two adjacent mounting holes 221 and the center is 90 degrees, and they hold the magnet 222 inside. Note that any method for holding the magnet 222 may be used, and for example, a method using a locking piece or the like that prevents the internal magnet 222 from falling out of the mounting hole 221 may be used.

[0046] (Configuration - Test equipment - Test fixture - Magnet) The magnet 222 is an output means that outputs magnetism from one or more locations selected from a plurality of locations on the proximity surface 223 to generate a magnetic field. The specific type and configuration of the magnet 222 are arbitrary, but for example, the magnet 222 is attached and fixed to the test jig 22 by being held inside the mounting hole 221, and four magnets are provided as shown in FIG. 6, and a permanent magnet that generates a magnetic field of any intensity level can be used. Note that the intensity level of the magnetic field generated by the magnet 222 is arbitrary, but for example, when the test jig 22 is used, it is used in proximity to the sensor 1 as shown in FIG. 1, and in this case, various rotation positions of the test jig 22 with respect to the sensor 1 (relative position in the circumferential direction of the test jig 22) are assumed as shown in FIGS. 7 and 8. Taking this assumption into consideration, the strength level of the magnetic field generated by each magnet 222 is determined so that, regardless of the relative position of the test jig 22 with respect to the sensor 1, when the test jig 22 is brought close to the sensor 1, the Hall IC 121 of the sensor 1 can detect a magnetic field of a strength level equal to or greater than a predetermined level (a level that allows the test section 151 of the sensor 1 to start testing).

[0047] (Configuration - Test equipment - Test fixture - Near surface) 4 and 5 is a surface that is in proximity to the sensor 1. The specific type and configuration of the proximity surface 223 are arbitrary, but for example, the proximity surface 223 has a shape that corresponds to the outer shape of the sensor 1.

[0048] (Configuration-Test Equipment-Test Jig-Cavity) 4 and 5 is a portion that penetrates the test jig 22. The specific type and configuration of this hollow portion 224 are arbitrary, but for example, it exposes and visibly displays the indicator light 131 in Fig. 7 provided on the lower side (-Z direction) of the sensor 1 in Fig. 1.

[0049] (test) Next, a test of the sensor 1 performed using the test device 2 thus configured will be described.

[0050] First, the user in FIG. 1 holds the support rod 21 of the test device 2 and presses the test jig 22 against the sensor 1 to bring it close to the sensor. In this case, various relative positions of the test jig 22 with respect to the sensor 1 in the circumferential direction of the test jig 22 are assumed, for example, as shown in FIG. 7 and FIG. 8, etc., but a magnetic field generated by a magnetism output from at least one magnet (for example, one or two magnets closest to the Hall IC 121) of the four magnets 222 is applied to the Hall IC 121, and the Hall IC 121 detects a magnetic field of a predetermined level or higher no matter what the relative position is. Then, the test section 151 of the sensor 1 performs a test because the Hall IC 121 detects a magnetic field of a predetermined level or higher. In this case, the light emission mode (light emission color and / or light emission pattern) of the indicator light 131 is arbitrarily changed to notify the status of the test (the fact that the sensor 1 has received a test signal, the type of test performed on the sensor 1, or the result of the test performed on the sensor 1). In this case, the user can visually check the indicator lamp 131 through the hollow portion 224 in FIG. 7 to ascertain the status of the test.

[0051] Note that the specific test performed here is arbitrary, and for example, if the testing section 151 is configured to select one of a plurality of types of tests (e.g., sensitivity test, alarm test, and fault test) according to the time that the Hall IC 121 continues to detect a magnetic field and perform the selected type of test, the user in Fig. 1 can perform a desired type of test by adjusting the timing of moving the test jig 22, which is close to the sensor 1, away from the sensor 1. This concludes the explanation of the tests.

[0052] (Effects of the embodiment) Thus, according to this embodiment, by outputting magnetism from one or more locations selected from multiple locations on the proximity surface 223, it is possible to reduce the effort required to position the test jig 22 relative to the sensor 1, for example, and therefore make it possible to test the sensor 1 efficiently.

[0053] Furthermore, by providing a plurality of magnets 222 fixed at a plurality of positions on the proximity surface 223, for example, since the magnets 222 are fixed to the test jig 22, a magnetic field can be stably output from a fixed position relative to the Hall IC 121 of the sensor 1, making it possible to reliably test the sensor 1.

[0054] Furthermore, by applying a magnetic field of a predetermined level or higher to the Hall IC 121 of the sensor 1 regardless of the relative orientation of the test jig 22 and the sensor 1, for example, the effort required for positioning the test jig 22 relative to the sensor 1 can be further reduced, making it possible to test the sensor 1 even more efficiently.

[0055] Furthermore, since the indicator light 131 of the detector 1 is exposed through the hollow portion 224 of the test jig 22, the indicator light 131 can be seen by a user performing a test using the test device 2, for example, so that the user can be made aware of the status of the test of the detector 1.

[0056] [Modifications to the embodiment] Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions described in the claims. Such modifications will be described below.

[0057] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and may vary depending on the implementation environment of the invention and the details of the configuration, and may solve only some of the problems described above or achieve only some of the effects described above.

[0058] (Regarding decentralization and integration) Furthermore, the above-mentioned configuration is a functional concept, and does not necessarily have to be physically configured as illustrated. In other words, the specific form of distribution or integration of each part is not limited to that illustrated, and all or part of it can be functionally or physically distributed or integrated in any unit. In this application, the term "system" is not limited to one configured by multiple devices, but includes one configured by a single device. In this application, the term "device" is not limited to one configured by a single device, but includes one configured by multiple devices.

[0059] (About magnets) In the above embodiment, the case where four magnets 222 are used as shown in Fig. 6 has been described, but the present invention is not limited to this. For example, two magnets, or five or more magnets may be used. The magnets 222 may be configured to be provided at any position in the circumferential direction of the test jig 22, regardless of the position of the mounting holes 221. For example, an electromagnet may be used as an output means instead of the magnets 222 or together with the magnets 222.

[0060] (For sensors with multiple Hall ICs) In the above embodiment, the sensor 1 in FIG. 7 is described as having one Hall IC 121, but a sensor having a plurality of Hall ICs may be assumed, and a test jig for testing the sensor may be configured. FIG. 9 is a bottom view of the test jig in a state where it is placed close to the sensor on the ceiling. The sensor 3 in FIG. 9 is configured similarly to the sensor 1 unless otherwise specified. The sensor 3 is a disaster prevention device, specifically, a disaster prevention device, and is configured to have, for example, two Hall ICs 321 and 322. A test section (not shown) of the sensor 3 is configured to select at least one type of test from among a plurality of types of tests based on which of the Hall ICs 321 and 322 detects a magnetic field of a predetermined level or higher, and to perform the selected at least one type of test. For example, the test section performs a sensitivity test when only the Hall IC 321 detects a magnetic field of a predetermined level or higher, performs an alarm test when only the Hall IC 322 detects a magnetic field of a predetermined level or higher, and performs a fault test when both the Hall ICs 321 and 322 detect a magnetic field of a predetermined level or higher.

[0061] The test jig 42 of the test device 4 of FIG. 9 is similar to the test jig 22 of the test device 2 of FIG. 7, except that only two magnets 4211 and 4212 are provided. These magnets 4211 and 4212 are magnetized so that, for example, when the magnets 4211 and 4212 are provided at positions facing the Hall ICs 321 and 322, only the facing Hall ICs detect a magnetic field of a predetermined level or higher. By using the test device 4 configured in this way, for example, by changing the rotation position of the test jig 42 with respect to the sensor 3 (the relative position in the circumferential direction of the test jig 42), it is possible to perform a desired test. For example, when the test jig 42 of FIG. 9 is rotated clockwise by about 80 degrees with the center of the test jig 42 as a reference, the magnet 4212 faces the Hall IC 321, and neither of the magnets 4212 and 4211 faces the Hall IC 322. In this case, since only the Hall IC 321 detects a magnetic field of a predetermined level or higher, the test section of the sensor 3 selects and performs a sensitivity test among the various tests. Also, for example, by appropriately rotating the test jig 42 in FIG. 9, when only the Hall IC 322 detects a magnetic field of a predetermined level or higher, the test section of the sensor 3 selects and performs an alarm test. Also, for example, by appropriately rotating the test jig 42 in FIG. 9, when both the Hall ICs 321 and 322 detect a magnetic field of a predetermined level or higher, the test section of the sensor 3 selects and performs a fault test. In this way, the user can appropriately rotate the test jig 42 in the state of being close to the sensor 3 by using a support rod (not shown) of the test device 4 to perform a desired test. By configuring in this manner, the rotational position of test jig 42 in close proximity to sensor 3 can be changed relative to sensor 3, so that one or more of the multiple magnets 4211, 4212 of test jig 42 selectively apply a magnetic field to one or more of the multiple Hall ICs 321, 322 of sensor 3. This makes it possible, for example, to use a single test jig 42 to perform multiple types of tests at the desired timing intended by the user.

[0062] In addition, it is also possible to use the test device 4 to perform desired tests on other sensors that operate by combining the operations of the test sections of the sensor 1 described in the above embodiment and the sensor 3 described in the modified example.

[0063] (Regarding the light receiving section and the processing section) Also, a light receiving unit and a processing unit may be provided for the test jig 22 of FIG. 4 and FIG. 5 of the above embodiment. The "light receiving unit" is a light receiving means that receives light from the indicator light 131 of the sensor 1 of FIG. 7 when the test jig 22 is brought close to the sensor 1. The specific type and configuration of this light receiving unit are arbitrary, but for example, it can be configured using a photodiode or the like, and can be provided in a part of the inner wall of the hollow part of FIG. 5 near the -Z side. The "processing unit" is a processing means that performs processing related to the sensor 1 based on the light receiving result of the light receiving unit. The specific type and configuration of such a processing unit are arbitrary, but for example, it can be configured in the same manner as the control unit 15 of the sensor 1, and it is a small-sized unit that can be provided inside the test jig 22 or on the outer periphery of the test jig 22. Then, for example, a battery or a cell is mounted on the test jig 22, and the above-mentioned components are configured to operate with the power supply voltage from the battery or cell. The processing unit may be configured to identify the state of the light received by the light receiving unit (i.e., the light emission state (light emission color and / or light emission pattern) of the indicator light 131) and, based on the identification result, determine the status of the test (the fact that the sensor 1 has received a user input for performing a test, the type of test performed by the sensor 1, or the result of the test performed by the sensor 1) or identify the identified light emission state. The test jig 22 may be provided with a speaker or a communication function, and the processing unit may be configured to output the determination result (i.e., the result of the test performed by the sensor 1, etc.) as audio from the speaker or to output the determination result to another device using the communication function. The processing unit may also be configured to output the identification result of the light emission state (for example, flashing green at three-second intervals or flashing red at one-second intervals, etc.) as audio from the speaker or to output the identification result to another device using the communication function.

[0064] With this configuration, for example, by performing processing related to the detector 1 based on the light receiving result of the light receiving section that receives the light of the indicator light 131 of the detector 1, it is possible to support, for example, the user's test operation of the detector 1, thereby improving convenience. Also, for example, by determining the test result of the detector 1, it is possible to allow the user to accurately recognize the test result. Also, for example, by identifying the light emission mode of the indicator light 131, it is possible to allow the user to accurately recognize the light emission mode of the indicator light 131.

[0065] (About the status output unit) A status output unit may be provided for the test device 2 of FIG. 1 of the above embodiment. The "status output unit" is a status output means that outputs the light emission status of the indicator light 131 of the detector 1 to the side opposite to the tip side of the support rod 21 (that is, for example, the side held by the user) when the test jig 22 is brought close to the detector 1. The specific type and configuration of the status output unit are arbitrary, but for example, the test jig 22 side can receive the light of the indicator light 131 of the detector 1 and can be configured using an optical fiber that guides the received light to the hand side of the support rod 21. In this case, when the detector 1 notifies the test status by the light emission of the indicator light 131, the light emitted is guided to the hand side of the support rod 21 by the optical fiber, so that the user can check the light emission state of the indicator light 131 at the hand side. By configuring in this way, for example, by outputting the light emission status of the indicator light 131 of the detector 1 to the side opposite to the tip side of the support rod 21, for example, the light emission status of the detector 1 can be visually confirmed at the user's hand.
