The present invention relates to an illuminance and luminance measuring apparatus, and more particularly, to an illuminance and luminance measuring apparatus in a tunnel for determining an illumination time or a lamp replacement time by measuring illuminance and luminance of a lighting facility in a tunnel. will be.

In general, measurements should be made in accordance with the Safety Design Standards of the Ministry of Construction and Transportation in Road Tunnels, "Design Standards for Lighting Facilities in Road Tunnels, KSC 7612,7613". The manual measurement method using a detector is used. For this reason, manual illuminance and luminance measurement methods require a lot of measurement time, the movement of vehicles must be controlled, and the measurement time is not free for the safety of measurement engineers even when the vehicle is controlled.

In addition, there is an inconvenience that the technician must record the measured values directly on a certain form paper by hand.

Therefore, the manual illuminance and luminance measurement method detects illuminance and luminance and may incorrectly input the tunnel illuminance and luminance detected when the technician records the tunnel illuminance and luminance for each measurement area while controlling the flow of vehicle traffic in the tunnel. Since the recorded tunnel illuminance and luminance must be calculated, the tunnel illuminance and luminance error are inevitably large.

On the other hand, recently, a technique for automatically measuring periodic illuminance and luminance by mounting a fixed measuring sensor in a tunnel has been proposed, but since foreign substances such as dust generated in the tunnel are accumulated in the measuring sensor, accurate measurement can be made. There was a problem of disappearing.

The present invention is proposed to improve the above-mentioned problems in illuminance and luminance measurement in the conventional tunnel, and the measurement sensor is normally stored in the enclosure so as to prevent adverse effects caused by foreign substances, while only being exposed to the outside during measurement work. The purpose of the present invention is to improve the reliability of illuminance and luminance measurement by providing a device that can be used.

The measuring device of the present invention for achieving the above object is fixedly installed in the tunnel, the enclosure formed with an entrance on one side; A sensor tray configured to allow entry and exit to the outside through an entrance and exit formed in the enclosure; An opening and closing door integrally formed at an end of the sensor tray for opening and closing of the entrance and exit; A measurement sensor configured in the sensor tray for measuring peripheral illumination and luminance; A tray driver for reciprocating the sensor tray in a horizontal direction; A rotating rod configured to be connected to the sensor tray by a hinge axis so that one side of the measuring sensor can move up and down within a predetermined height range; In addition to controlling the operation of the tray drive unit is characterized in that a configuration including a controller that stores the data measured by the measurement sensor.

In the tunnel illuminance and luminance measuring device of the present invention, since the measurement sensor for measuring the illuminance and luminance in the tunnel is always stored inside the enclosure, it is selectively exposed to the outside only during the measurement operation, The adverse effect caused by this can be prevented, thereby improving the measurement reliability.

In particular, as the measurement sensor is exposed to the outside and the driving is made to a certain height, it is possible to improve the measurement reliability.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to the schematic structure of the illuminance and luminance measurement apparatus in the tunnel according to the first embodiment of the present invention through FIGS. 1 to 4, the enclosure 10 fixed in the tunnel has an entrance 11 at one side wall. Is formed in the housing 10, the sensor tray 30 is configured to allow access to the outside through the doorway 11, integral with the end of the sensor tray 30 for opening and closing of the doorway (11) Furnace opening and closing door 20 was provided, the sensor tray 30 is configured with a measuring sensor 40 for measuring the ambient illumination and luminance. In particular, one side of the measuring sensor 40 is preferably configured with a horizontal sensor 41 to confirm that the measuring sensor 40 can always maintain a horizontal state.

In addition, an MCU (Machine Control Unit) controller 60, which controls the operation of the tray driving unit and stores data measured by the measurement sensor 40, is installed inside the enclosure 10. The antenna 62 is configured to connect wirelessly to transmit data signals to an external central control apparatus or the like.

On the other hand, as a tray drive for reciprocating the sensor tray 30 in the horizontal direction, the guide block 52 is mounted on the bottom surface of the rear end of the sensor tray 30, and the guide block 52 is driven in the form of a screw engagement It can be seen that the driving motor 50 is configured such that the screw 51 is horizontally penetrated and the horizontal and horizontal reciprocating movement of the sensor tray 30 is performed by driving the driving screw 51 in the forward / reverse direction.

Then, at the interruption of the tray 30, the rotating rod 35 for raising and lowering the measuring sensor 40 within a predetermined height range was connected to the hinge shaft 31, and the rotating shaft 35 was connected to the hinge shaft 31. ) Is configured with an elastic spring 32 for supporting a predetermined elastic force, and pressurizes the rotation rod 35 when the sensor tray 30 enters the inside of the housing 10 to the entrance 11 side. The guide roller 12 for lowering is comprised.

In addition, the entrance and exit 11 can be seen that the cleaning brush 13 is provided so that the foreign matter on the measurement sensor 40 in the process of moving the sensor tray 30 can be automatically removed.

In the drawing, reference numeral 36 is a sensor plate on which the measurement sensor 40 and the horizontal sensor 41 are seated, and 61 represents a connection cable connecting the sensor tray 30 and the controller 60.

The effects of the operation of the present invention illuminance and luminance measuring device constituting such a structure will be described.

The device of the present invention is installed inside the tunnel so that the measurement sensor 40 is normally stored inside the housing 10 so that the accumulation of external dust and foreign substances is prevented, and the measurement sensor 40 is periodically exposed to the outside. As a result, it is used to measure illuminance and luminance at each position of the tunnel.

That is, in the measurement operation, when the driving motor 50 is driven by the control signal of the controller 60, as the driving screw 51 is rotated, the guide block 52 screwed with the driving screw 51 is The sensor tray 30 is moved horizontally outward.

Then, as the movement of the sensor tray 30 is made, the pressing force of the rotating rod 35 pressed by the guide roller 14 is released, so that the rotating rod 35 is driven by the elastic force of the elastic spring 32. It is raised around the hinge axis 31 and thus the measuring sensor 40 is at an elevated position.

As such, the exposure of the measurement sensor 40 to the elevated position prevents shadow interference caused by the housing 10 or the like, thereby measuring illuminance and luminance inside the tunnel.

In addition, since the horizontal state of the measuring sensor 40 is measured by the horizontal sensor 41, the measuring operation can be performed in a more stable state, thereby maximizing measurement reliability.

And, the data obtained through the measurement work is transmitted to the central control unit (not shown) through the communication equipment of the controller 60, or stored in the internal storage to the data to confirm the change in the illumination and luminance in the tunnel. Can be used.

That is, in this case, the driving screw 51 is rotated in the reverse direction by the driving of the driving motor 50, so that the sensor tray 30 is moved into the housing 10 by the action of the guide block 52. In this movement process, the rotating rod 35 is pressed by the guide roller 12 so that the lowering of the measuring sensor 40 is achieved by rotating in the downward direction about the hinge shaft 31.

In addition, due to the cleaning brush 14 installed at the entrance 11 in the process of the internal movement of the sensor tray 30, foreign matters such as dust on the measuring sensor 40 can be automatically removed, so that the measurement reliability of the sensor It can be seen that to maximize.

When the sensor tray 30 is moved to its original position, the opening / closing door 20 configured at one end of the sensor tray 30 closes the entrance 11 so that the inflow of foreign matter such as dust from the outside is blocked. Will be achieved.

Therefore, the device of the present invention is selectively exposed to the outside only during the measurement work in the state that the measuring sensor 40 is always stored inside the housing 10, thereby preventing adverse effects due to dust or foreign matter and thus It can be seen that the measurement reliability can be improved.

On the other hand, Figure 5 shows a schematic diagram of a device remote monitoring system according to another embodiment of the present invention.
