1 is a configuration diagram of an unmanned overload control system according to an embodiment of the present invention, and FIG. 2 is a detailed configuration diagram of a load-bearing machine system according to an embodiment of the present invention.

Referring to FIG. 1 , the unmanned overload control system 100 may include a load-bearing machine system 110 , a vehicle recognition and information collection system 120 , a vehicle information display system 130 , and the like.

Here, in relation to the present invention, at least one of the vehicle recognition and information collection system 120 and the vehicle information display system 130 may not be included in the unmanned overload control system 100 . On the other hand, other components not shown may be further included to configure the unmanned overload control system 100 .

In addition, in FIG. 1 , for example, each component system constituting the unmanned overload control system 100 is illustrated as a single configuration, but is not limited thereto. For example, a plurality of axle loader systems 110 shown in FIG. 1, at least one vehicle recognition and information collection system 120, and at least one vehicle information display system 130 are combined to form the unmanned overload control system 100 ) can also be implemented.

The shaft weight system 110 includes an axle weight measurement sensor unit 111 , a wheel position reading sensor unit 112 , a vehicle detection and classification sensor unit (loop) 113 , and a temperature sensor unit for shaft weight correction 114 . ), the data control device 115 may be configured to include at least one or the like.

1 and 2, the configuration of the accumulator system 110 will be described in more detail as follows. Here, for convenience, one lane will be described as an example. In addition, the configuration of the weight bearing system 110 for each lane may or may not be the same. For example, in relation to speed enforcement, a normal overtaking lane and a driving lane may not have the same structure of the heavy-duty machine 110 .

The axle weight measurement sensor unit 111 senses an axle weight (overloaded axle) and a total weight (total overload) of the vehicle being driven. In FIG. 2, two of the first axial load measuring sensor and the second axial load measuring sensor are shown, but the present invention is not limited thereto. Each axial load measuring sensor acquires a sensing value according to the lateral response characteristic of the sensor. In the above, the lateral direction means a lateral direction with respect to a vehicle traveling direction. In addition, the sensed value according to the lateral response characteristic of the sensor may indicate a sensed value according to left-biased, middle, and right-biased. It is possible to reduce the measurement error by correcting the measured value through the axial load measuring sensor based on the sensed value according to the lateral response characteristic of the sensor.

The sensor of the axial weight measurement sensor unit 111 may use, for example, any one of the sensors of the drawing shown in FIG. 3 . In this case, the characteristics according to each sensor are different, and the same sensor may be used for both the first axial load measuring sensor and the second axial load measuring sensor shown in FIG. 2 , and different sensors may be used.

The sensor of the piezo film type has signal characteristics after installation of the package as shown in Fig. 3(a), and as shown in Fig. 3(b), the precision is about +-7%, low cost, and the temperature and lateral It has a sensor characteristic with a high directional impact error, and as shown in FIG. More than -15%, shaft weight has a system accuracy of more than +-25%.

The sensor of the piezoceramic type has signal characteristics after installation of the package as shown in Fig. 3(a), and as shown in Fig. 3(b), the precision is about +-7%, low to mid-priced, and temperature and lateral It has a sensor characteristic with a high directional impact error, and as shown in FIG. The axle weight has a system accuracy within +-20 to 25%.

The piezo-Qualz type sensor has signal characteristics after installation of the package as shown in (a) of FIG. 3, and as shown in FIG. It has a sensor characteristic with a low directional impact error, and as shown in FIG. Within, the shaft weight has a system accuracy within +-10 to 14%.

Any one of the above three sensors can be selected. It is desirable to determine the sensor by paying attention to the fact that the sensor only shows the response of the deformation of the pavement due to the traffic load, and the pavement may have different deformation depending on the characteristics even under the same load, and that it always behaves with the temperature change.

In general, the response processing for the above-described sensor may be performed as follows. Taking a fixed axle as an example, it is possible to measure the weight of a vehicle by converting the size (height) of the signal under load into weight, which is similar to the measurement principle of a general scale. Alternatively, the integral area of the signal waveform sensed by the sensor is converted into weight, which may improve accuracy in response to a speed change.

The wheel position reading sensor unit 112 functions to assist the sensor measurement value, detect an avoidance vehicle, and the like. An example of such a sensor may be a wandering sensor. At this time, instead of measuring through one extended wondering sensor in one lane, a plurality of wondering sensors are installed to correspond to each wheel of the vehicle, for example, to reduce or eliminate mutual interference between the left and right wheels through the wondering sensor, It is possible to read the lateral running position of each wheel, read the track of each wheel axis, and distinguish between single and double wheels of each tire. Through this, by analyzing the lateral load distribution characteristics, it is possible to classify the vehicle type by heightening it, and it is also possible to analyze the vehicle leaving the lane.

The vehicle detection and classification sensor unit (loop) 113 functions to process vehicle speed and basic vehicle model information. In FIG. 2 , a first loop and a second loop are illustrated, and each loop may be disposed before the axial load measuring sensor based on the vehicle traveling direction. However, the present invention is not limited thereto. In addition, each loop may be formed to have an appropriate width according to each lane.

The axial weight correction temperature sensor unit 114, referring to FIG. 1, may correct the sensor value by comparing the upper temperature and the lower temperature through the temperature sensor. For example, when the upper temperature is higher than the lower temperature, the measurement error of the measured value can be reduced by calculating the sensor value as excessive and, in the opposite case, calculating the sensor value as insufficient and correcting the measurement value.

The data control device 115 includes at least one of a terminal box 115 and a collection device 210 , referring to FIG. 2 . Taking the collecting device 210 as an example for convenience, the terminal box 115 is connected to each sensor unit to receive the sensing value of the corresponding sensor unit, and the sensed value of each sensor unit thus received is transmitted to the collecting unit 210 . Here, the collection device 210 may collect sensing data of all terminal boxes connected through any one of the terminal boxes. However, the present invention is not limited thereto. For convenience, in FIG. 2 , one shaft weight measurement sensor unit 111 , one wheel position reading sensor unit 112 , one vehicle detection and classification sensor unit 113 , and one shaft weight correction temperature sensor unit installed in each lane. (114), but is not necessarily limited thereto. For example, in FIG. 2, two terminal boxes are shown, a first terminal box and a second terminal box, and the sensing data of the first terminal box is received from the second terminal box and transmitted together to the collection device 210, but directly from each terminal box. The sensing data may be transmitted to the collection device 210 . Meanwhile, the terminal box 115 may be omitted, and sensing data may be transmitted directly from each sensor unit to the collection device 210 . On the other hand, the collection device 210 is described as being connected to the terminal box by wire at a predetermined distance, but is not limited thereto. In addition, although the terminal box(s) is installed as it is, the collecting device 210 does not exist, and sensing data may be transmitted to a remotely located collecting device based on wired/wireless communication.

The collection device 210 may be implemented in the form of, for example, a remotely located control terminal, a control device, or a server.

In other words, each component in the unmanned overload control system 100 or the accumulator system 110 may perform data communication with each other using at least one communication protocol. In this case, for the data communication, a dedicated communication protocol may be defined and used according to an embodiment. However, the present invention is not limited thereto, and data communication may be performed using various communication protocols currently developed or developed in the future (including existing communication protocols). In addition, the communication protocol between each component is not necessarily the same, and if necessary, data may be appropriately converted and used according to the communication protocol according to the embodiment.

Through pattern recognition, it is possible to extract a vehicle to avoid enforcement, and it is also possible to improve the vehicle type classification function. Through this, it is possible to develop or upgrade the performance of an unmanned or non-stop overload control system.

As described above, the deviation adjustment in the conventional heavy-duty system is performed after the manager connects the terminal directly to the weight-bearing control device at the site where the weight-bearing machine is installed, acquires driving test data in the test vehicle, calculates the deviation adjustment value, and then It was a method that was reflected in the accumulator control system. Therefore, a lot of time and manpower was consumed in the above method.

Accordingly, in the present invention, without a separate site manager, by performing data communication through wireless communication between the test vehicle 410 and the load-bearing machine control device 420 in the field, deviation adjustment can be made automatically.

First, referring to FIG. 4 , the load-bearing machine deviation adjustment system is an embodiment in which a test vehicle 410 and a load-bearing machine control device 420 are implemented, and separate wireless communication devices 415 and 425 are provided respectively.

Through this, according to an embodiment of the present invention, data is exchanged between the test vehicle 410 and the load-bearing machine control device 420 through wireless communication, and the load-bearing machine control device 420 calculates a deviation adjustment value. This can automatically adjust the deviation.

In the above, wireless communication refers to data communication performed through various communication networks such as public wireless communication network, self wireless communication network, mobile communication network, 3G, LTE, LTE-A, and the like. Briefly, the wireless communication means performing data communication between components through a wireless communication network.

According to the embodiment, in a specific case, for example, when security is required, a dedicated wireless communication network supporting a communication protocol defined separately for a security network or a weight shift adjustment system according to the present invention may be used. On the other hand, a wired network may be used between some of the components in the load-bearing machine deviation adjustment system.

Meanwhile, the first wireless communication device 415 of the test vehicle 410 of FIG. 4 may be implemented, for example, in a vehicle-mounted, fixed or detachable form.

The first wireless communication device 415 includes both fixed and portable devices, and may be described as a terminal.

Meanwhile, the first wireless communication device 415 is, for example, any one of a smart phone, a smart pad, a laptop computer, etc. including a sensing module capable of sensing location data such as a Global Positioning System (GPS), or a configuration thereof. can

Alternatively, the first wireless communication device 415 may be a dedicated wireless communication device for adjusting the deviation of the accumulator for the present invention. According to an embodiment, the second wireless communication device 425 may also be the same.

On the other hand, the first wireless communication device 415 may use a dedicated application for adjusting the deviation of the accumulator system according to the present invention. Therefore, the first wireless communication device 415 is automatically paired with the second wireless communication device 425 of the load-bearing machine control device 420 by downloading and installing the application in advance, and then executing the application to receive a separate input or Data may be exchanged with each other without user action, and deviation value calculation, deviation adjustment, etc. may be automatically performed by the load-bearing machine control device 420 . However, the present invention is not limited thereto. For example, a web service type, a cloud service type, etc. related to the present invention may be used instead of the application. According to an embodiment, the second wireless communication device 425 may also be the same.

Referring to FIG. 7 , the deviation adjustment process of the accumulator control device 420 using wireless communication according to an embodiment of the present invention may be performed as follows.

Here, the wireless communication device 415 of the test vehicle 410 only broadcasts data, receives the data broadcast from the load weight control device 420, parses it, and uses it to adjust the deviation. .

Alternatively, the first wireless communication device 415 transmits to a pre-entered destination, but it is preferable that the load-bearing machine control device 420 track the movement of the test vehicle 410 . For example, the first wireless communication device 415 may transmit data in units of seconds.

In addition, although not shown, a dedicated channel is used for data transmission/reception between the test vehicle 410 and the load weight control device 420, or a separate transmission/reception signal or data frame is promised in advance. It can also be determined and used to adjust the deviation of the accumulator based on it.

When the test vehicle 410 information is received through the second wireless communication device 425 (S702), the load-bearing machine control device 420 in the field starts tracking the movement of the test vehicle 410 (S703), Based on the information provided by the test vehicle 410, an estimated time to reach the axle weight sensor detecting unit 111 is calculated (S704).

In the above, the expected arrival time of the axle weight sensor detecting unit 111 of the test vehicle 410 may be calculated using the latitude and longitude coordinates previously input to the axle weight control device 420 .

The test vehicle 410 compares and selects whether the vehicle information provided by the test vehicle 410 matches the vehicle information provided by the test vehicle 410 from the vehicle information of the axle weight control device 420 at the time of passing the axle weight sensor detecting unit 111 . (Matching) is possible (S705).

When the selection (matching) of the test vehicle 410 is completed with the data detected by the load-bearing machine control device 420 through the step S705, the load-bearing machine control device 420 transmits the detection data through the second wireless communication device 425. and the number of deviation selections can be transmitted (S706).

When the number of trips previously input to the first wireless communication device 415 of the test vehicle 410 and the number of selections transmitted from the load-bearing machine control device 420 match each other, a test end message is sent to the load-bearing machine controller 420 . By transmitting the data, the test of the corresponding lane may be terminated (S707).

When the test end message is received, it is possible to calculate a correction coefficient based on the test measurement data detected by the pivot control device 420 and adjust the deviation reflecting this (S708).

Transmission and reception in the above step may vary depending on the viewpoint.

In FIG. 4 described above, the second wireless communication device 425 is an embodiment of the case where it is attached to or connected to the load weight control device 420 . On the other hand, FIG. 5 is an embodiment of the case in which the second wireless communication device 425 in FIG. 4 has a built-in load weight control device 420 . In this case, the second wireless communication device may be modularized like a wireless communication (support) module.

Alternatively, referring to FIG. 6 , data transmission/reception between the wireless communication devices in FIG. 4 or data transmission/reception between the wireless communication (support) module of the first wireless communication device 415 and the accumulator control device 420 as shown in FIG. 5 is performed. This is an embodiment for a case of indirectly performing through the server 430 rather than directly.

For example, the server 430 is remotely located hardware and may be referred to as a processor, and receives data between the aforementioned test vehicle 410 and the heavy lifting machine control device 420 to i) only other It is possible to generate control data through simple transmission to the configuration, or ii) data comparison, analysis, and the like and deliver it to the configuration.

In addition, in the above-mentioned FIG. 6 , the server 430 may be replaced with or passed through a relay for wireless communication support between the test vehicle 410 and the load-bearing machine control device 420 .

In addition, in connection with the present invention, the above-described embodiments of Figs. 4 to 6 can be appropriately combined to implement a wireless communication-based heavyweight deviation adjustment system. For example, if the case of FIGS. 4 to 5 is impossible depending on the communication environment, the case of FIG. 6 may be tried and used. The opposite is also true. Alternatively, both cases of FIGS. 4 or 5 and 6 may be used for the purpose of mutual verification or improvement of data reliability.
