Description

[Technical Field]

[0001] The present invention relates to a fire detector adapter for use with a fire detector. [Background technology]

[0002] When a fire detector installed in a building that is being monitored for fires detects an abnormality, malfunction, or false fire alarm, an environmental survey of the fire detector installation site may be conducted. In an environmental survey, a sensor that measures the environment is placed near the fire detector for a certain period of time to obtain data that shows the environment of the installation location, such as temperature and humidity. For example, data is obtained that shows that the temperature and humidity near the bathroom are higher than in a normal room.

[0003] On the other hand, as shown in Patent Document 1, smoke detectors and the like in fire detectors are generally attached to a detector base by rotating the fire detector so that the locking piece of the detector base attached to the ceiling or the like is clamped by a connecting spring provided on the fire detector.

DETAILED DESCRIPTION OF THE INVENTION

[0009] FIG. 7 shows a conventional installation state of a fire detector 1 on a ceiling panel C. FIG. 7 is a side view. Conventionally, a detector base 2 is fixed to the ceiling panel C, and the fire detector 1 is removably attached to the detector base 2. The outer periphery of the mounting portion of the fire detector 1 and detector base 2 is circular, and by pressing the fire detector 1 against the detector base 2 and rotating it in a twisting motion, a locking piece (not shown) on the detector base 2 engages with a connecting spring (not shown) provided on the fire detector 1, thereby achieving installation. In addition, by rotating the fire detector 1 in the opposite direction, the engagement between the connecting spring and locking piece is released, allowing the fire detector 1 to be removed from the detector base 2. [Example]

[0010] FIG. 1 shows a side view of the fire detector adapter 3 of the first embodiment installed. The detector base 2 is fixed to a ceiling panel C, as in the conventional example. The fire detector adapter 3 is detachably attached to the detector base 2, and the fire detector 1 is detachably attached to the fire detector adapter 3. The attachment structure between the detector base 2 and the fire detector adapter 3 is the same as the attachment structure between the detector base 2 and the fire detector 1 in the conventional example. The attachment structure between the fire detector adapter 3 and the fire detector 1 is also the same as the structure in the conventional example. In FIG. 1 and FIG. 3, which will be described later, the surface of the fire detector adapter 3 that is closer to the ceiling panel C and that comes into contact with the detector base 2 is provided with a base attachment portion 3b, which is a connection spring similar to that of the fire detector 1. The surface of the fire detector adapter 3 that is farther from the ceiling panel C and that comes into contact with the fire detector 1 is provided with a locking piece similar to that of the detector base 2, which is a detector attachment portion 3a. The fire detector adapter 3 can be sandwiched between a conventional detector base 2 and fire detector 1 and installed in an overlapping state, which prevents airflow from being obstructed to the fire detector 1 as compared to when an environmental measurement device is installed around the fire detector 1. The fire detector adapter 3 can be fitted with the fire detector 1, and is attached to the installation surface via the detector base 2 to which the fire detector 1 can be attached.

[0011] As shown in Figure 1, the fire detector adapter 3 has a roughly cylindrical shape with the same radius as the fire detector 1 and detector base 2. As mentioned above, the fire detector adapter 3 is installed so as to overlap the fire detector 1 and detector base 2, and therefore its shape fits within the external shape of the fire detector 1, so it has little impact on the design of the installation location.

[0012] The fire detector adapter 3 also allows airflow to flow in through multiple openings 38 formed in a cylindrical wall 37 that forms the outer peripheral side surface. Figure 2 shows a bottom view of the fire detector adapter 3 when attached to the ceiling panel C in Figure 1. Figure 2 is a view from the direction of the detector mounting portion 3a where the fire detector 1 is attached. The bottom surface of the fire detector adapter 3 is recessed and surrounded by the cylindrical wall 37, and is provided with a locking piece 39 that is clamped between the connecting spring of the environmental sensor and the fire detector 1. The environmental sensor is a sensor that can measure environmental factors different from the target sensed by the detection sensor 11 in the fire detector 1, and one or more environmental sensors are provided. If multiple environmental sensors are provided, it is preferable to provide sensors that can measure different environmental factors. In the example of Figure 2, three types of environmental sensors are provided, one each near the center.

[0013] The environmental sensors in Example 1 are a temperature sensor 31, a humidity sensor 32, and an acceleration sensor 33. The fire detector 1 is a smoke detector that measures scattered light from smoke. The environmental sensors measure temperature, humidity, and acceleration, which are environmental factors different from scattered light from smoke. Air near the installed fire detector 1 flows into the fire detector adapter 3 shown in FIG. 2 through the opening 38 shown in FIG. 1, and the temperature is measured by the temperature sensor 31 and the humidity is measured by the humidity sensor 32. In addition, vibrations transmitted to the fire detector 1 are measured by the acceleration sensor 33.

[0014] Fig. 3 shows a connection diagram of the fire detector adapter 3 in Example 1. The fire detector adapter 3 has a detector mounting portion 3a to which the fire detector 1 is attached, and a base mounting portion 3b to which the detector base 2 is attached. The wiring leading to the detection sensor 11 of the fire detector 1 passes through the fire detector adapter 3 and connects to the detector base 2. The oval in Fig. 3 indicates a detachable connection made by a locking piece and a connecting spring.

[0015] The fire detector adapter 3 is provided with environmental sensors, namely, a temperature sensor 31, a humidity sensor 32, and an acceleration sensor 33, and each of the environmental sensors is connected to a control unit 34. The control unit 34 is also connected to a transmission unit 36. The transmission unit 36 ​​transmits environmental data via wireless LAN. The transmitted environmental data is then sent to a management server (not shown) that manages the fire detector 1 via the Internet. The transmitted environmental data is then used as data for predicting deterioration of the fire detector 1, etc. In the first embodiment, the environmental sensors, control unit 34, etc. of the fire detector adapter 3 are not connected to wiring that connects to the fire detector 1.

[0016] The temperature sensor 31, humidity sensor 32, acceleration sensor 33, control unit 34, and transmission unit 36 ​​are driven by a battery 35 mounted on the fire detector adapter 3. By providing the battery 35 in the fire detector adapter 3 without using the power supply voltage of the fire detector 1, there is no need to receive an additional voltage supply from the fire receiver to drive the fire detector adapter 3.

[0017] <Variation 1> FIG. 4 shows a bottom view of the fire detector adapter 4 according to Modification 1, which is a modification of Example 1. In Modification 1, two environmental sensors, namely, two temperature sensors 41, two humidity sensors 42, and two acceleration sensors 43, are provided. The fire detector adapter 4 has openings on its outer periphery, similar to the opening 38 of the fire detector adapter 3 of Example 1 shown in FIG. 1 . The temperature sensors 41, the humidity sensors 42, and the acceleration sensors 43 are provided near the openings, near the cylindrical wall 47. When providing multiple sensors in this manner, arranging them facing each other or spaced apart can reduce the effect of the direction of the incoming airflow on the data. In the example shown in FIG. 4, the two temperature sensors 41 are provided at separate positions on the underside of the fire detector adapter 4. The same is true for the humidity sensors 42 and 43. Therefore, as in Example 1, outside air can easily reach the environmental sensors through the openings on the outer periphery of the fire detector adapter 4. In the first modification, if there is no need to provide two acceleration sensors that do not measure air, only one may be provided. [Example]

[0018] Fig. 5 shows a connection diagram of the fire detector adapter 5 in Example 2. The fire detector adapter 5 has a detector mounting portion 5a to which the fire detector 1 is attached, and a base mounting portion 5b to which the detector base 2 is attached. The wiring leading to the detection sensor 11 of the fire detector 1 passes through the fire detector adapter 5 and is connected to the detector base 2. The oval in Fig. 5 indicates a detachable connection portion using a locking piece and a connecting spring. The fire detector adapter 5 is attachable to the fire detector 1, and is attached to an installation surface via the detector base 2 to which the fire detector 1 can be attached.

[0019] The fire detector adapter 5 is provided with environmental sensors, namely, a temperature sensor 51, a humidity sensor 52, and a gas sensor 53, and each environmental sensor is connected to a control unit 54. The gas sensor 53 measures carbon dioxide concentration. The control unit 54 is also connected to wiring leading to the fire detector 1. The environmental sensors measure environmental factors different from the target detected by the detection sensor 11 in the fire detector 1. The fire detector 1 is a smoke detector that measures scattered light from smoke. The environmental sensors measure temperature, humidity, and carbon dioxide concentration, which are environmental factors different from scattered light from smoke.

[0020] The detection data output from the detection sensor 11 is input to the control unit 54. The control unit 54 corrects the detection data using environmental data such as temperature, humidity, and carbon dioxide concentration measured by the environmental sensors, and transmits the corrected data to a fire receiver (not shown) via the detector base 2. In this way, by detecting fires using the detection data from the detection sensor 11 of the fire detector 1 and the environmental data from the fire detector adapter 5, it is possible not only to investigate the environment of the installation location, but also to suppress false fire alarms by controlling the threshold value if false fire alarms are likely to occur, thereby making it possible to issue a reliable fire alarm.

[0021] In the second embodiment, as in the first embodiment, the temperature sensor 51, the humidity sensor 52, the gas sensor 53, and the control unit 54 are driven by the battery 55 mounted in the fire detector adapter 5. Also in the second embodiment, when a plurality of environmental sensors are provided, the sensors are arranged near the openings provided on the outer periphery of the fire detector adapter 5, thereby reducing the directionality of the inflow of airflow and enabling quick and accurate correction. [Example]

[0022] Fig. 6 shows a connection diagram of the fire detector adapter 6 in Example 3. The fire detector adapter 6 has a detector mounting portion 6a to which the fire detector 1 is attached, and a base mounting portion 6b to which the detector base 2 is attached. The wiring leading to the detection sensor 11 of the fire detector 1 passes through the fire detector adapter 6 and is connected to the detector base 2. The oval in Fig. 6 indicates a detachable connection portion using a locking piece and a connecting spring. The fire detector adapter 6 is attachable to the fire detector 1, and is attached to an installation surface via the detector base 2 to which the fire detector 1 can be attached.

[0023] The fire detector adapter 6 is provided with environmental sensors, namely a temperature sensor 61, a humidity sensor 62, and an acceleration sensor 63, and each environmental sensor is connected to a control unit 64. The environmental sensors measure environmental factors different from the target of detection by the detection sensor 11 in the fire detector 1. The fire detector 1 is a smoke detector that measures scattered light from smoke. The environmental sensors measure temperature, humidity, and acceleration, which are environmental factors different from scattered light from smoke.

[0024] The control unit 64 is also connected to a memory unit 66. Environmental data measured by the environmental sensor is stored in the non-volatile memory unit 66. The control unit 64 is also connected to an output terminal 68 via an output unit 67. When the fire detector adapter 6 is installed, the output terminal 68 is located between the detector base 2 and the fire detector adapter 6, and is hidden from the outside.

[0025] In the third embodiment, similarly to the first embodiment, the environmental sensor, the control unit 64, etc. of the fire detector adapter 6 are not connected to the wiring that connects to the fire detector 1 or the detector base 2. The temperature sensor 61, the humidity sensor 62, the acceleration sensor 63, the control unit 64, etc. are driven by a battery 65 mounted in the fire detector adapter 6.

[0026] The fire detector adapter 6 of the third embodiment is used to collect environmental data. In the third embodiment, the fire detector adapter 6 installed between the fire detector 1 and the detector base 2 collects environmental data using a temperature sensor 61, a humidity sensor 62, and an acceleration sensor 63, and stores the collected data in a non-volatile memory unit 66. When the data collection period ends, the fire detector adapter 6 is removed from between the fire detector 1 and the detector base 2 and connected to a personal computer (not shown). Then, in response to a transmission request from the personal computer, the environmental data is downloaded from the memory unit 66 of the fire detector adapter 6 to the personal computer via the control unit 64, output unit 67, and output terminal 68.

[0027] <Variation 2> In the fire detector adapter 6 of Example 3, the environmental data stored in the memory unit 66 is transferred to a personal computer via the output terminal 68. In Modification 2, the memory unit 66 is a removable non-volatile memory such as a small USB flash memory (registered trademark).The memory unit 66 is then removed from the fire detector adapter and connected to a personal computer, and the environmental data is transferred.

[0028] <Variation 3> As a third modification, a transmitter for Bluetooth (registered trademark), which is a short-range wireless communication, may be provided instead of providing the output terminal 68. In the third modification, when collecting environmental data, the portable personal computer is brought close to the installed fire detector adapter, and the environmental data is downloaded via Bluetooth in response to a transmission request from the personal computer. The third modification downloads the environmental data when the personal computer is brought close to the fire detector adapter, which differs from the first embodiment in that the environmental data is sent from a wireless LAN to the management server via the Internet.

[0029] In the above-described embodiment and modified example, a battery is provided as the power source for the fire detector adapter. However, the voltage of the wiring of the detector base may also be used as the power source. Furthermore, as a method for reducing the power consumption of the battery 35 of the fire detector adapter 3 of the first embodiment, the fire detector adapter 3 may not be constantly powered on, but may be configured to be powered on when data is output from the fire detector adapter 3 or when the acquired value in the fire detector 1 exceeds a certain level. This is also true for the other embodiments.

[0030] In the second embodiment, it has been described that non-fire alarms are suppressed using the data acquired by the fire detector 1 and the environmental data acquired by the fire detector adapter 5. In the first to third embodiments, the environmental data of the fire detector adapter can also be used to determine whether the installation location of the fire detector 1 is appropriate.

[0031] Furthermore, the specific configuration is not limited to the embodiments, and the present invention includes design changes within the scope of the gist of the present invention. Furthermore, the above-mentioned examples and modifications can be combined by utilizing each other's technology as long as there are no particular contradictions or problems in the purpose, configuration, etc. [Explanation of symbols]
