The control unit (5) is a power supply switching device 21 for supplying and cutting off DC power input from the outside, as shown in FIG. A power protection unit 22 controlling the power applied from the power switch 21 to flow stably; Receives a signal from the fan and heater control circuit 23 and the limit switch 11, the temperature sensor 12 to control the fan and the heater to operate by the power applied from the power switch 21, the power switch Each of the device 21 and the power protection device 22 is composed of a CPU board 24 that receives a signal and controls the operation of the general equipment.

The CPU board 24 controls the operation by self-diagnostic function and fan and heater contact control regarding door state, temperature, battery charge / discharge state, power failure state, etc., and is provided in the communication device protection device 8 with an overcurrent blocking function. It protects the power supply from the surge and shock current, transmits the self-diagnosis and control result to the vehicle controller, and controls the power supply stably by monitoring the power failure.

As shown in FIG. 5, the power supply unit 4 includes a power battery 31 and a DC-DC regulator 32. The DC-DC regulator 32 includes a rectifier circuit, an overcharge / discharge protection circuit, and a DC. It consists of a DC converter. In addition, the power supply unit 4 may be provided with a solar panel.

Here, the solar panel is an independent power source for continuously supplying power to the power battery 31 when the AC power is short-circuited. That is, the solar panel can be fixed to the upper end of the connecting pipe 43 connected to the structure anchor 42 embedded in the pedestal 400, which will be described later, and can be fixed to the outside of the body if necessary A structure can be installed and attached to the top of the structure. The solar panel is connected to the DC-DC regulator 32 to charge the power battery 31.

The power supply unit configured as described above converts commercial power (AC) into DC power, and also converts DC power input through the solar panel of the main body into DC power, and protects the battery from overcharging and overdischarging. Extends and supplies stable power through the battery even if the power is shorted.

The communication device protection device 8 according to the present embodiment includes a ground copper plate for ground connection of the device in the main body 1, a terminal block for connecting DC power, a surge breaker, a relay switch, and a surge introduced through a communication line. It consists of a surge protector for communication that protects circuits / equipment, and a surge protector for power that protects circuits / devices from surges coming from the power line.

In addition, the temperature sensor 12 sets the operation of the heater to 30 ° and the fan operating temperature to 15 ° to control the heater and the fan does not operate between the operating range of the heater and the fan, that is, 15 ~ 30 ° will be. In addition, the fan is configured to cool by heat transfer instead of cooling by air circulation inside and outside the main body, thereby effectively protecting the main body from rain, dust, dust, and the like.

As shown in FIG. 6, the seat 400 is partially embedded with a movement latch 41 for coupling to a main body at a square end, and a structure anchor 42 for connecting an external communication line and a power line to one side thereof. Is provided, the other side has a structure in which the power supply line, the communication line, the grounding line connecting pipe 43 is drawn out from the basement to the inside of the main body.

Referring to the working state of the present invention configured as described above are as follows.

First, the housing 300 is made of a cabinet form, but is made of a closed type completely closed with the outside, by simply connecting the main body (1) to the mobile clasp 41 provided on the base 400 to enable a simple field installation do. In addition, the communication cable embedded in the basement is introduced into the main body 1 through the pipe 43 embedded in the base (4000), thereby making it very simple to connect the wire and power lines.

The control unit 5, the power supply unit 4, and the communication device protection device 8 are mounted in the rack 3 in the main body 1 in a state in which the housing 300 is installed on the base 400. The constant temperature, humidity, It performs dustproof, waterproof, soot and oil blocking, self-diagnosis and control, and collects vehicle detection information according to rapidly increasing traffic demand.

That is, the CPU board 24 of the controller 5 receives the temperature and the temperature limit signal inside the enclosure detected by the temperature sensor 12 and the limit switch 11 to control the temperature inside the enclosure, The control signal is applied to turn on the lighting 15 according to whether the opening and closing of 1a) is performed. In addition, the CPU board 24 monitors data related to data collection and communication related to a battery charge / discharge state and a power failure state and diagnoses itself. In addition, the contact control of the fan and the heater 7 allows the temperature inside the enclosure 300 to be always maintained within a predetermined temperature range, and protects the power by controlling the operation of the power switch 21.

Also, upon request from the vehicle controller or periodically, the self-diagnosis and control results are transmitted from the vehicle controller mounted inside the enclosure to the regional controller or the traffic control center so that smooth traffic flow can be achieved.

On the other hand, during maintenance or replacement of the housing 300 in the vehicle detection process, the opening and closing door (1a) to open and rotate the rack frame (2) counterclockwise to work. Therefore, during installation and maintenance work on the roadside, the operator can safely work on the front of the rack while watching the road situation at the same position as the work on the back of the rack.

In addition, by continuously supplying power to each device in the housing 300 in a battery operation method using a commercial power source and a solar panel it is possible to ensure a stable operation of the vehicle detector.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, according to the present invention, by enclosing the enclosure completely, it is possible to reliably block contaminants such as dust, dust, etc. generated on the road, thereby preventing malfunction of the internal device of the enclosure. It has the effect of stably collecting vehicle detection information by performing self-diagnosis and traffic related control functions for internal devices.

In addition, since the rack frame in the enclosure is rotatably installed, not only can the replacement and maintenance of the enclosure be secured, but also the congestion of the road caused by the maintenance can be eliminated. Has a simple different effect.
