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

(Constitution)
First, the configuration of the sensor according to the present embodiment will be described. FIG. 1 is a side view when the sensor according to the embodiment of the present invention is being tested, and FIG. 2 is a block diagram showing the sensor. In FIG. 1, a part of the sensor 1 is actually hidden behind the test jig 22 and cannot be seen, but it is drawn by a solid line for convenience. The sensor 1 of FIG. 2 is a prevention device, and includes, for example, 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.

(Configuration-Physical quantity detector)
The physical quantity detecting unit 11 is a physical quantity detecting means for detecting a physical quantity related to an abnormal fire. The specific type and configuration of the physical quantity detection unit 11 are arbitrary, but can be configured by using, for example, a smoke detection space or a smoke detection means for detecting the concentration of smoke that has entered the smoke detection space. As the smoke detecting means, 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 are used as a scattered light type or a dimming type. Can be configured.

(Structure-Magnetic field detector)
The magnetic field detection unit 12 is a magnetic field detection means for detecting a test signal input from a predetermined proximity region outside the sensor 1. The specific type and configuration of the magnetic field detection unit 12 are arbitrary, but for example, a test signal is provided at a predetermined position of the test jig 22 provided at the tip of the support rod 21 of the test device 2 shown in FIG. It is assumed that a magnet that outputs magnetism (for example, a permanent magnet) is provided, and when the test jig 22 is brought close to the sensor 1, the magnetic field generated by magnetism, which is a test signal output from the magnet, is detected. In addition, it can be configured by using a Hall IC (detection means) or the like. Here, for example, it will be described that only one Hall IC of the magnetic field detection unit 12 is provided at a predetermined position in the sensor 1.

(Configuration-Information output unit)
The information output unit 13 is an information output means for outputting information related to the sensor 1. The specific type and configuration of the information output unit are arbitrary, but for example, the indicator lamp 131 and the like shown in FIG. 1 can be provided. The indicator lamp 131 is a light emitting means that emits light to the outside of the sensor 1, and can be configured by using, for example, a light source such as an LED. Here, since the test jig 22 of FIG. 1 has a tubular shape having a hollow portion penetrating, the indicator lamp 131 passes through the hollow portion even when the test jig 22 is close to the sensor 1. The user will be able to visually recognize the indicator lamp 131.

(Configuration-Recording unit)
Returning to FIG. 2, the recording unit 14 is a recording means for recording a program and various data necessary for the operation of the sensor 1, and is configured by using, for example, a flash memory. However, any recording medium can be used instead of the flash memory.

(Configuration-Control unit)
The control unit 15 is a control means for controlling the sensor 1, and specifically, a CPU, various programs interpreted and executed on the CPU (basic control programs such as an OS, and specific functions started on the OS). It is a computer configured with an internal memory such as a RAM for storing the program and various data) and an application program for realizing the above. In particular, the control program according to the embodiment is installed in the sensor 1 via an arbitrary recording medium or network to substantially configure each part of the control unit 15.

In terms of function concept, the control unit 15 includes, for example, a test unit 151. The test unit 151 is a test means for testing the sensor 1 based on the test signal detected by the Hall IC of the magnetic field detection unit 12, and specifically, the pretest signal of the Hall IC of the magnetic field detection unit 12. It is a means of selecting at least one of a plurality of types of tests based on the detection duration and performing at least one selected type of test. The processing performed by each unit of the control unit 15 will be described later.

(processing)
Next, the test process executed by the sensor 1 of FIG. 2 configured in this way will be described. FIG. 3 is a flowchart of the test process (steps are abbreviated as “S” in the following description of each process). The "test process" is a process related to a test, and specifically, a process for performing a sensitivity test or an alarm test. The timing of executing this test process is arbitrary, but for example, it will be described from the point where the test process is started, assuming that the test process is started and executed when the power of the sensor 1 is turned on.

In SA1 of FIG. 3, the test unit 151 determines whether or not to perform the test. Specifically, although it is arbitrary, for example, whether or not the output value of the Hall IC of the magnetic field detection unit 12 is monitored and the Hall IC detects a magnetic field of a predetermined level or more for a predetermined time (for example, 0.5 seconds or the like) or more. Is determined, and the determination is made based on the determination result. When it is determined that the Hall IC has not detected a magnetic field of a predetermined level or higher for a predetermined time or longer, it is determined that the test signal has not been accepted because the test signal has not been detected continuously for a predetermined time or longer. , It is determined that the test is not performed (NO of SA1), and SA1 is repeatedly executed until it is determined that the test is performed. Further, when it is determined that the Hall IC has detected a magnetic field of a predetermined level or higher for a predetermined time or longer, it is determined that the test signal has been received because the test signal has been continuously detected for a predetermined time or longer, and the test is performed. After the determination (YES of SA1), the process proceeds to SA2.

Here, for example, as shown in FIG. 1, when the user brings the test jig 22 of the test device 2 close to the sensor 1 for a predetermined time or longer, a predetermined level generated by the magnetism output from the magnet of the test jig 22 Since the above magnetic field is applied to the Hall IC for a predetermined time or longer, it is determined that the test signal has been received and the test is performed.

In SA2 of FIG. 3, the test unit 151 outputs information (status related to the test) indicating that the sensor 1 has received the test signal. FIG. 4 is a diagram showing the light emission timing of the indicator lamp, (a) shows a normal time when the test is not performed, (b) shows a case where the sensitivity test is performed, and (c). ) Indicates the case where a notification test is performed. In FIG. 4, as shown in FIG. 4A, large and small pulses indicate the time at 1-second intervals, and the timing at which the large pulse (hereinafter, large pulse) emits light is indicated. Other than this large pulse (that is, a small pulse (small pulse) and a portion where the pulse is not shown) indicate the timing at which light is not emitted. Further, the light emission of the indicator lamp 131 is controlled by the control unit 15 in the same manner as in the conventional case. For example, it will be described below assuming that the indicator lamp 131 blinks green at intervals of 3 seconds by emitting green light at the timing of the large pulse shown in the figure at the normal time shown in FIG. 4 (a). ..

The processing of SA2 in FIG. 3 is specifically arbitrary, but for example, the test signal can be changed by changing the light emitting mode of the indicator lamp 131 to a light emitting mode indicating that the sensor 1 has received the test signal. Outputs information indicating acceptance. Specifically, the indicator light 131 blinks 5 times at 1-second intervals. Here, for example, at the timing T11 of FIG. 4B, when the user determines that the test jig 22 is brought close to the sensor 1 and the test is performed by the SA1, the subsequent five large pulses are used. At the timing, the indicator light 131 is made to emit light in red 5 times, so that the indicator light 131 blinks in red 5 times. In this case, the user can grasp that the sensor 1 has received the test signal by visually recognizing the emission color and emission pattern of the indicator lamp 131.

In SA3 of FIG. 3, the test unit 151 selects a test. Specifically, although it is optional, for example, it is assumed that the sensor 1 has a function of performing a sensitivity test and an alarm test, and any test is selected. Specifically, the Hall IC of the magnetic field detection unit 12 is monitored, the time during which the Hall IC continues to detect the magnetic field from the time when the test signal is received is specified, and when the specified time is less than the type determination time, the sensitivity Select the test, and if the specified time is equal to or longer than the type determination time, select the alarm test. The "time during which the Hall IC continues to detect the magnetic field" here corresponds to the "time for detecting the test signal". Here, the “type determination time” is a time that serves as a reference for selecting a test, and specifically, is a time that serves as a reference for determining a test intended by the user. It is 9 seconds or the like corresponding to the time interval T12 shown in 4 (b). The "when the test signal is received" here is, for example, as shown in FIG. 4 (b), the timing corresponding to the first large pulse among the five large pulses (that is, the indicator lamp 131). Will be described below as corresponding to the timing of the first light emission when the light is emitted five times in red.

Here, for example, at the timing T11 of FIG. 4B, when the user brings the test jig 22 close to the sensor 1 and then moves the test jig 22 away from the sensor 1 at a timing during the time interval T12. Since the time that the Hall IC continues to detect the magnetic field is less than the time for determining the type, the sensitivity test is selected. Further, for example, when the user brings the test jig 22 close to the sensor 1 at the timing T11 of FIG. 4C, and then moves the test jig 22 away from the sensor 1 at a timing after the lapse of the time interval T12. Since the time that the Hall IC continues to detect the magnetic field is equal to or longer than the time for determining the type, the alarm test is selected.

In SA4 of FIG. 3, the test unit 151 conducts a test. Specifically, although it is optional, for example, the test selected by SA3 is performed. Since the specific contents of the sensitivity test and the alarm test performed here are known, only the outline will be described.

Specifically, when the sensitivity test is selected in SA3, the zero point of the sensor 1 is specified by an arbitrary method, it is determined whether or not the specified zero point is within the specified range, and the determination result is displayed by the indicator lamp 131. Output via. The output method of the determination result is arbitrary, but for example, when the zero point is within the specified range, the timing of the large pulse after the time interval T12 in FIG. 4B is to output the normal determination result. (That is, FIG. 4 (a) returns to the normal light emission). On the other hand, for example, when the zero point is not within the specified range, the indicator lamp 131 is made to emit red light at the timing of a large pulse after the time interval T12 in FIG. 4B in order to output an abnormal determination result. As a result, it blinks red at intervals of 3 seconds.

Further, when the alarm test is selected in SA4, the process of outputting the alarm signal is performed in the same manner as when the detector 1 detects a fire, and when the alarm signal is output normally, FIG. 4C shows. At the timing indicated by the large pulse of T13, the indicator light 131 is made to emit light in red (that is, the indicator light 131 is continuously turned on in red). It should be noted that the light emission of the indicator lamp 131 is maintained until a known reset operation is performed.

In these cases, the user can grasp the type of the test performed by the sensor 1 and the result of the test by visually recognizing the emission color and the emission pattern of the indicator lamp 131. This completes the test process.

(Effect of embodiment)
As described above, according to the present embodiment, at least one of a plurality of types of tests is selected based on the detection duration of the test signal by the Hall IC of the magnetic field detection unit 12, and at least one selected type. By performing the above tests, for example, various tests can be performed. Further, for example, since the test can be selected by a simple operation of moving the test jig 22 of the test device 2 that outputs the test signal closer to or further away from the sensor 1, the intended test can be performed on the ceiling or the like. It is possible to perform it reliably and easily without removing it from the installation location.

Further, by performing the test when the test signal is continuously detected for a predetermined time or longer, it is possible to prevent the test from being performed against the intention of the user due to, for example, disturbance.

Further, by emitting the indicator lamp 131 in a light emitting mode corresponding to the situation related to the test with the sensor 1, the situation related to the test with the sensor 1 is notified, for example, the situation related to the test is notified to the user. It becomes possible to recognize.

In addition, by notifying the reception of the test signal, the type of the test performed by the sensor 1, or the result of the test performed by the sensor 1, for example, various situations related to the test can be notified to the user. It becomes possible to recognize.

Further, the plurality of types of tests include at least a sensitivity test and a reporting test, so that, for example, various functions of the sensor 1 can be tested.

Further, by detecting a signal based on magnetism as a test signal, for example, a test can be performed with a test jig 22 equipped with a magnet that does not require a power supply or the like and is relatively inexpensive and easy to handle. Therefore, the sensor 1 is tested. It is possible to reduce the cost for this.
