Description

The present invention relates to a radiant heat detecting device and a radiant heat measuring device using a radiant sensor, and more specifically, to a radiant heat measuring technique capable of detecting not only the amount of radiant heat but also the direction (vector) of radiant heat.

In measuring radiant heat, conventionally, a black thermometer in which a thermometer is housed in the center of a black sphere having an emissivity of 1 is generally used.

However, since the black thermometer receives the radiant heat from the surroundings with a hollow black globe and measures the temperature at the center thereof, it is not possible to know from which direction the radiant heat is generated.

For example, in a room in winter, warm radiant heat arrives from the direction in which the heater is located, and cold radiant radiation arrives at a window with low heat insulation performance, but this difference cannot be detected (measured). There is also a problem that the reaction is slow because the temperature is measured by a thermometer.

Further, according to the radiant sensor (thermal radiant flux sensor) proposed in Patent Document 1, only the radiant heat applied to the surface can be detected quickly and with high sensitivity without attaching an infrared filter window or the like. Regarding the direction of radiant heat, the measurer had no choice but to judge in which direction the radiant sensor was directed.

Next, some embodiments of the present invention will be described with reference to FIGS. 1 to 9, but the present invention is not limited thereto.

First, referring to FIG. 1, the radiant heat measuring device according to this embodiment displays the measurement result based on the sensor unit 1 that detects the radiant heat and the radiant heat data detected by the sensor unit 1 as a basic configuration. It is provided with a measuring instrument main body 2 to be used.

The sensor unit 1 (radiant heat detection device) includes a plurality of radiant sensors 10a to 10n. Since the radiation sensors 10a to 10n have the same configuration, when it is not necessary to distinguish between them, the radiation sensors 10 are collectively referred to as the radiation sensors 10. In the present invention, each radiation sensor 10 is attached to a three-dimensional support (preferably a heat sink) in different directions, as will be described later.

For each radiation sensor 10, a "radiation sensor RF series (see Patent Document 1 above)" manufactured by CAPTEC is suitable. This radiant sensor is thin and flexible with a thickness of 0.3 mm (it can be curved to a radius of 30 mm), and outputs a voltage proportional to radiant heat with a response time of about 0.05 seconds.

The measuring instrument main body 2 includes an input unit 21, a control unit 22, a memory 23, a display unit 24, and an operation unit 25. In this embodiment, the input unit 21 has a multiplexer function, sequentially switches the radiant heat signal (output voltage) from the radiant sensors 10a to 10n, performs A / D conversion, and gives the radiant heat signal to the control unit 22.

A CPU (Central Processing Unit) or a microcomputer may be used for the control unit 22. The control unit 22 is given direction information from the operation unit 25 in which direction the radiation sensors 10a to 10n are directed.

The memory 23 includes a ROM area in which an execution program or the like for the control unit 22 is written, and a work RAM area for work. The display unit 24 is preferably a liquid crystal display panel, but a printer may be used.

Next, the first embodiment of the sensor unit (radiant heat detection device) 1 will be described with reference to FIGS. 2 and 3. The sensor unit 1a according to the first embodiment includes a hexahedral heat sink 12 as a support, and radiation sensors 10 (10a to 10f) are provided on each surface (four surfaces in the circumferential direction and two surfaces of the upper surface and the lower surface). ) Is attached. Each radiation sensor 10 is always kept at a constant temperature by the heat sink 12.

The support that supports the sensor preferably has a heat sink function that keeps the temperature of the radiant sensor 10 substantially constant, but the radiant heat sensor 10 used in this embodiment uses a heat sink for a short time. Practical level measurement is possible without it. Therefore, the support does not necessarily have to be a heat sink, and may be a hollow body or a medium entity having no heat sink function.

The heat sink 12 is preferably water-cooled, but air-cooled may be adopted. The heat sink 12 may be integrally formed by, for example, aluminum die casting, or may be formed into a hexahedron by combining heat sink blocks that are predeterminedly divided.

Further, when the heat sink blocks are combined to form a hexahedron, the radiation sensor 10 may be attached to each heat sink block in advance and combined. Further, it is not necessary to provide the radiation sensor 10 on all the surfaces, and according to the first embodiment, the present invention also includes an embodiment in which the radiation sensor 10 is provided only on the four surfaces in the circumferential direction.

In the first embodiment, a support column 13 for supporting the sensor unit 1a is provided on the lower surface of the sensor unit 1a, and water supply pipes 13a and 13b for circulating cooling water to the heat sink 12 are provided in the support column 13. It has been inserted. Instead of the support column 13, the sensor unit 1a may be suspended by a cable or the like.

The control unit 22 is given direction information (direction in charge) of each radiation sensor 10 in advance from the operation unit 25. For example, assuming that the radiation sensors 10a to 10d are in charge of a range of 90 ° divided into four equal parts in the horizontal plane, the radiation sensor 10e is in charge of the upward range, and the radiation sensor 11f is in charge of the downward range, the direction information of each radiation sensor 10 is the control unit 22. Given to.

As a result, when the control unit 22 acquires the amount of radiant heat from each radiant sensor 10 via the input unit 21 and displays it on the display unit 24, the direction information of the radiant sensor 10 is added and displayed.

As an example, in a winter room, if there is a heating device on the radiant sensor 10a side and the radiant sensor 10c on the opposite side is directed to a window with low heat insulation performance, there is warm radiant heat from the radiant sensor 10a side. On the other hand, it can be seen that heat is taken away to the window side to which the radiation sensor 10c is directed (cold radiation that makes people feel cold).

Next, the sensor unit (radiant heat detection device) 1b according to the second embodiment will be described with reference to FIG. The sensor unit 1b has a spherical heat sink (not shown), the upper hemisphere is divided into four equal parts, radiation sensors 10a to 10d are attached to the four equal surfaces thereof, and the lower hemisphere is similarly divided into four equal parts. , Radiation sensors 10e to 10h are attached to the four surfaces.

According to this, the amount of radiant heat from each direction can be displayed vectorically by giving the control unit 22 direction information (direction in charge) for each of the radiant sensors 10a to 10d and the radiant sensors 10e to 10h in advance. it can. As an example, FIG. 5 shows a vector display example of the amount of radiant heat detected by the radiant sensors 10a to 10d provided in the upper hemisphere.

Next, the sensor unit (radiant heat detection device) 1c according to the third embodiment will be described with reference to FIGS. 6 and 7. In the sensor unit 1c, the heat sink 12 has a disk shape, for example, a radiation sensor 10 is arranged on a part of the peripheral surface thereof, a rotating shaft 32 driven by a motor 31 is attached to the center of the heat sink 12, and the radiation sensor 10 is rotated. It is movable along an arc centered on the shaft 32. As another example of the heat sink, the heat sink 12 may have a triangular shape, a radiation sensor 10 on one surface thereof may be arranged, and the apex portion of the diagonal thereof may be supported by the rotation shaft 32. Further, the rotation shaft 32 may be manually rotated.

According to this, one radiant sensor 10 can measure radiant heat over a range of 360 °. In this case, the rotation shaft 32 is provided with, for example, a rotation position detecting means including a perforated disk and an optical sensor, and the rotation position detection means gives the control unit 22 the rotation position information of the radiation sensor 10, as shown in FIG. As described above, the radiant heat detected over a range of 360 ° in the horizontal plane can be displayed in a vector manner.

When the heat sink 12 is a water-cooled type, the water supply pipe for circulating cooling water is pulled out from the heat sink 12, so that the radiation sensor 10 preferably rotates reciprocally within a range of 360 °.

Next, the sensor unit (radiant heat detection device) 1d according to the fourth embodiment will be described with reference to FIGS. 8 and 9. The sensor unit 1d uses a gyro mechanism 40 to enable detection of radiant heat in all directions.

As shown in FIG. 8, the gyro mechanism 40 includes two first and second rotating shafts 41 and 42 and two first and second frames 43 and 44 as a basic configuration. .. The rotation axes 41 and 42 are oriented so as to be orthogonal to each other.

On the other hand, the first frame 43 is vertically erected, and the first rotating shaft 41 is horizontally attached to the upper end thereof. The second frame 44 is rotatably supported on the first rotating shaft 41 in a substantially U shape. The second rotating shaft 42 is attached to the second frame 44 so as to be orthogonal to the first rotating shaft 41.

The radiation sensor 10 is arranged on a part of the peripheral surface of the disk-shaped heat sink 12 as described in FIG. 6 in the third embodiment, and the center of the heat sink 12 is supported by the second rotating shaft 42. ing.

According to the gyro mechanism 40, the radiation sensor 10 can rotate 360 ° in a vertical plane with the first rotation axis 41 as the horizontal rotation axis, and is orthogonal to the second rotation axis 42 about the second rotation axis 42. Since it can rotate 360 ° in a plane, radiant heat can be detected in all directions.

FIG. 9 shows an example of vector display of radiant heat detected in all directions by the radiant sensor 10. This vector display includes rotation position information in the horizontal plane and rotation position information in the vertical plane of the radiation sensor 10.

In particular, in the case of the third embodiment and the fourth embodiment in which the radiant sensor 10 is movable, the amount of radiant heat detected by the radiant heat sensor 10 is A / D converted to Bluetooth (registered) on the heat sink (support) 12. It is preferable to have a function of transmitting data wirelessly such as (trademark) and a function of receiving the data on the measuring instrument main body 2 side. Of course, this data transmission / reception function may be applied to the first embodiment and the second embodiment.

Further, although the hexahedron is divided into eight in the first embodiment and the spherical surface is divided into eight in the second embodiment, the present invention is not limited to this. Further, also in the third embodiment and the fourth embodiment, for example, two radiation sensors may be supported on the peripheral surface of the disk-shaped heat sink 12 at an interval of 180 °.
