Description

A traffic detector device and vehicle information with high and low speed weight}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high speed, low speed dual purpose axle, vehicle information, and traffic detection device.

In general, as a method of measuring vehicle information and traffic volume, non-contact sensors such as microwave detectors, ultrasonic sensors, and lasers are installed on a road on which a vehicle travels to investigate vehicle information and traffic volume traveling on a road. The cost of installing a detector and a laser is increased, and the information obtained through the non-contact sensor appears completely different depending on the condition of the road, the weather, the surrounding environment, and the type of road (asphalt road, concrete road, etc.). There was a problem that it was difficult to measure information and traffic volume.

Thus, as described above, without using a sensor installed on the road in a non-contact manner, as shown in Patent Registration No. 10-731808, only a loop circuit sensor or a piezo sensor circuit is installed on the road, and between the axles measured by each sensor. Vehicle information was obtained by measuring only the distance or the vehicle length.

However, when only the distance between the vehicle axle and the vehicle length is measured as described above, even if a vehicle having a similar displacement has different vehicle information according to the distance between the vehicle axles, there is a problem that the vehicle information cannot be properly understood.

In addition, the piezo sensor for measuring the vehicle information and weight is to check the vehicle information by the vibration generated by the driving of the vehicle, when the vehicle is running at a low speed, the vibration is hardly generated by the speed of the vehicle so that the piezo There was a problem that the sensor does not properly grasp the vehicle driving on the road.

In addition, since the speed of the vehicle passing through the piezo sensor is high, the tire is not in contact with the narrow narrow piezo sensor or is instantaneously contacted, which causes the piezo sensor not to properly grasp vehicle information.

Meanwhile, in order to grasp vehicle information, a device called a trapdle was installed in the toll gate to grasp vehicle information passing through the toll gate.

As described above, the tracks installed in the toll gate measure only the vehicle width, the number of wheels, and the distance between the toll gates, distinguish the vehicle information through the toll gate, and collect charges according to the vehicle type.

In addition, when there are many freight vehicles passing through the toll gate by passing the freight vehicle passing through the toll gate only to one place that overcharges, there is a problem that the freight vehicles passing through the toll gate are stagnated.

In addition, since the tracks installed in the toll gate only measure the width of the vehicle, the distance between the axles, and the like, there is a problem in that it is not possible to determine whether the freight vehicle is overloaded, so that a weighing platform for measuring the weight of the freight vehicle must be separately installed.

According to the present invention, vehicle widths, tire widths, distances between axles, and vehicle weights of vehicles traveling on general roads, highways, and toll gates are comprehensively measured at one location using a weight measuring unit and a contactless switch, thereby driving vehicle information. And high-speed, low-speed multi-purpose condenser, vehicle information, and traffic detection system that can check the traffic volume as a whole, and accurately determine whether the vehicle is overloaded to prevent damage to the road due to the vehicle's overload.

By comprehensively measuring in one place, it is possible to collectively check the vehicle information and the traffic volume driving on the road, and to accurately determine whether the vehicle is overloaded, and to prevent the damage of the road due to the vehicle's overload. have.

In addition, vehicle information and traffic volume can be checked regardless of the speed of the vehicle driving on the road, and the toll gate can be passed to other lanes to measure the weight of the vehicle at the toll gate. By accurately measuring the vehicle information passing through and the weight of the vehicle at the same time, to accurately collect the charge according to the vehicle information passing through the toll gate, there is an advantage that can prevent the vehicle push phenomenon in the toll gate.

In addition, it is a useful invention having the advantage of preventing overloading of the vehicle by dividing the charge according to the vehicle weight and the type of vehicle in detail into various types.

In addition, as the wheels of the vehicle are in contact with both the pad and the solid state switch of the weighing unit, the contact area of the vehicle wheel becomes wider, and thus there is an advantage of accurately measuring the vehicle information and the vehicle weight.

Looking at the configuration of the high speed, low speed combined lift and vehicle information, traffic detection device of the present invention for achieving the above object as follows.

And a piezoelectric sensor circuit 18 (referred to as a band-shaped sensor circuit), and it is preferable to combine a plurality of pads 15 coupled to the frame 11.

Here, the solid state switch 20 is a piezoelectric sensor 21, as shown in Figure 4 is not a band-shaped sensor circuit is coupled to a plurality of piezoelectric sensor 21 and the circuit board 22 combined non- The contact switch 20 is referred to.

Weighing apparatus for re-measuring the vehicle weight with respect to the vehicle overload and the communication unit 19c for transmitting the data measured by the image photographing unit (19b) and the weight measuring unit 10 and the solid state switch (20) 19d) (the commonly used condenser) and the central control unit 19 is installed, and the mobile terminal (H) (mobile condenser, indicator, fixed condenser, etc.) which can be conveniently checked while the administrator is moving. It is preferable to manufacture it further).

Herein, the mobile terminal H transmits and receives data to and from the indicator h1 (notebook, etc.) that can be used by a manager, such as the central control unit 19, and the communication unit 19c of the central control unit 19. (h2), a screen display device h3 such as a monitor, and a movable concentrator h4.

Hereinafter will be described the most preferred embodiment of the present invention.

First, an arbitrary point of a road (general road, highway, toll gate, etc.) is cut by a predetermined size, and then the frame 11 is installed on the cut road.

In addition, a strain gauge 12 for detecting a vehicle weight is installed in the installation groove 13 of the pad 15 according to the degree of bending of the pad 15, and a plurality of the pads 15 are provided on the upper side of the frame 11. Arrange dogs throughout the roadway.

Here, when the pad 15 is installed in the frame 11, it is coupled using a bolt (not shown in the figure) for firm coupling, and the frame 11 and the pad 15 are grooved by bolts. It is obvious that (h) is formed.

In addition, after the piezoelectric sensor 21 and the circuit board 22 for controlling the numerical values measured by the piezoelectric sensor 21 are coupled to the frame 11 installed on the road, the contactless switch 20 is manufactured. The solid state switch 20 is arranged on the frame 11 in the frame 11 at regular intervals (for example, 1 cm, 2 cm, etc.).

In addition, the piezoelectric sensor 21 may be replaced by a commonly used roof coil (not shown).

Here, after fabricating the contactless switch 20, it is preferable to perform epoxy molding to prevent the contactless switch 20 from malfunctioning due to moisture or moisture.

Then, the pad 15 and the pointless switch 20 are installed in the frame 11, and the loop sensor circuit 17 or the piezo sensor circuit 18 is installed in the front and rear directions of the frame 11 in the road traveling direction. Install).

Here, the loop sensor circuit 17 or piezo sensor circuit 18 refers to a band-shaped circuit sensor that is generally installed on the road.

The solid state switch 20 is a switch that does not have a mechanical contact, and uses a switching characteristic of a semiconductor device that produces a state where a resistance value is close to 0 (ON) and a state near infinity (OFF). Diodes, Hall elements, etc. are used, and there are many advantages in characteristics and maintenance compared to general switches, and especially when switching to flammable gas when high speed interruption is required for electronic circuits. Say the appropriate switch.

In addition, the weight measuring unit 10 and the contactless switch 20 is installed on the road, and an image photographing unit 19b and a weight measuring unit for photographing a vehicle traveling on the road with a screen display unit 19a such as an electric sign. 10) and the communication unit 19c for transmitting and receiving the measured data on the contactless switch 20, and the weighing apparatus 19d (generally used) that can re-measure the vehicle weight with respect to the overload core vehicle. It may further include a central control unit 19 that is installed, such as a vehicle weight measuring device, weighing table, a weight lifter, etc., and a portable terminal (H) (mobile type lifter) that allows the administrator to check the status of the vehicle. , A fixed scale lifter, an indicator, etc., also called a statutory meter).

After the weight measuring unit 10 and the contactless switch 20 are installed on the road as described above, when the vehicle passes, the front axle of the vehicle is the front of the weight measuring unit 10 and the contactless switch 20. After passing through the loop sensor circuit 17 or the piezo sensor circuit 18 installed in the vehicle, the loop sensor circuit 17 or the piezo sensor circuit 18 detects the front axle of the vehicle while generating electromotive force by vibration according to the vehicle weight. The width or tire width is measured.

In addition, the front wheel of the vehicle passing through the loop sensor circuit 17 or the piezo sensor circuit 18 becomes excessively above the solid state switch 20. At this time, the solid state switch 20 is fixed to the entire frame 11 at a predetermined interval. The contactless switch 20 installed by the width of the vehicle wheel detects the vehicle.

Here, the piezoelectric sensor 21 of the contactless switch 20 should detect the vibrations transmitted to the road to detect the tire width and the vehicle width of the vehicle accurately by a certain pressure or more.

Thus, the solid state switch 20 is provided with a circuit board 22 for controlling the piezoelectric sensor 21 for detecting the vibration.

This is because the piezoelectric sensor 21 detects even a small vibration of the vehicle, and thus cannot accurately measure the width or tire width of the vehicle.

Thus, when the piezo sensor 21 detects the vibration of the vehicle, it detects the vibration by a certain weight (for example, to detect the weight of the vehicle 100kg or more), so that the width and tire width of the vehicle accurately Measure it.

For example, if five piezoelectric sensors 21 of the piezoelectric sensors 21 are arranged at a predetermined interval due to vibration in a vehicle and detect the vibration of the vehicle, the piezoelectric sensors 21 generate electromotive force. The circuit board 22 installed in the solid state switch 20 detects vibration caused by the load transmitted to the piezoelectric sensor 21 to stop operation of the piezoelectric sensor 21 that detects vibration of 100 kg or less. By controlling only the piezoelectric sensor 21 which detects the vibration of kg or more, it functions to accurately measure only the wheels located above the piezoelectric sensor 21 to accurately measure the width of the vehicle and the tire width.

When the wheel of the vehicle passes through the loop sensor circuit 17 or the piezo sensor circuit 18 and passes through the contactless switch 20, the vehicle wheel is positioned on the pad 15 of the weighing unit 10. As the pad 15 is bent, the strain gauge 12 formed in the installation groove 13 of the pad 15 senses the degree of bending of the pad 15 to measure the vehicle weight.

Here, the pad 15 is formed with a bending groove 14, so that the weight of the vehicle is transmitted only to the center of the pad 15, so that the weight of the vehicle positioned above the pad 15 can be accurately measured. do.

Then, as shown in FIG. 6, after the vehicle passes the weight measuring unit 10, the weight is measured while passing through the loop sensor circuit 17 or the piezo sensor circuit 18 installed at the rear of the weight measuring unit 10. The vehicle width and the tire width are measured in the same manner in the loop sensor circuit 17 or the piezo sensor circuit 18 installed in front of the unit 10 and the contactless switch 20 in the same manner.

Then, the front axle of the vehicle is measured in the same manner as described above, and as the vehicle moves forward, the rear axle of the vehicle is measured in the same manner as described above.

Thus, by measuring the vehicle information and the vehicle weight according to the distance and vehicle width, tire width, etc. according to the time of the front and rear axles of the vehicle, and outputs the vehicle information and the vehicle weight measured through the screen display unit 19a such as an electronic sign B. The driver may check and transmit the data output on the screen display unit 19a to the administrator through the communication unit 19c so that the vehicle information and the vehicle weight can be checked even at a long distance.

In addition, after measuring the vehicle weight, the overload core vehicle is moved to a separately loaded weighing apparatus 19d (also called a legal weighing instrument such as a general weighing scale or a scale lifter) to re-measure the vehicle weight. do.

On the other hand, although the manager may check the vehicle information and the vehicle weight while staying in the central control unit 19, the manager directly refers to the mobile terminal H (mobile scaler, fixed scaler, indicator, etc., also called a statutory meter). After carrying or fixed on one side of the road, the vehicle can pass through the vehicle information and vehicle weight can be measured.

The portable terminal H is also called a fixed legal meter or a mobile legal meter.

In addition, the central control unit 19 is further provided with an image photographing unit 19b, it is possible to utilize the traffic volume survey data by photographing the vehicle traveling on the road or passing through the toll gate.

In this case, the mobile terminal H transmits and receives data with the indicator h1 (notebook, etc.) that can be used by a manager, such as the central control unit 19, and the communication unit 19c of the central control unit 19. The communication device h2, a screen display device h3 such as a monitor, and a mobile concentrator h4 are included.

In addition, the weight measuring unit 10 and the contactless switch 20 are installed in the toll gate so that the vehicle passing through the toll gate can be accurately collected for each class of vehicle (in the past, the fee was divided into six types). do.

For example, even if the vehicle's displacement and the same type of vehicle are collected separately by the fee according to the weight (divided into 11 types according to the car type and the weight), it is possible to accurately charge the usage fee according to the road driving.

In addition, the manager who manages the road based on the information generated through the above method can conveniently maintain and manage the road (general national road, highway, toll gate, etc.) by checking the traffic volume such as the vehicle information driving according to the type of road. It will be possible.

In addition, when the weight measuring unit 10 and the contactless switch 20 are installed at each gate of the toll gate as described above, the truck does not need to pass through only one gate to the van, even if the traffic of the van increases. In addition, the loading of the gate can prevent the vehicle from sliding.
