Description

Belt conveyor real-time transport volume monitoring using an 80 GHz band radar sensor and an optimal control system for front and rear mechanical equipment using this data {Belt Conveyer Cargo Conveying Control System Using 80 GHz Radar Sensor}

The present invention relates to an optimal control system for mechanical equipment installed at the front and rear ends of a belt conveyor. More specifically, it relates to real-time monitoring of belt conveyor transport volume using a radar sensor in the 80 GHz band and optimal control of mechanical equipment at the front and rear ends using this data. It's about the system.

The present invention is not limited to recycled aggregate and is applicable to plant systems equipped with all crushing and sorting facilities.

In general, recycled aggregate refers to aggregate made so that it can be used as a construction material through a physical or chemical treatment process of construction waste. It is used in the construction of waste concrete, waste bricks, waste blocks, etc. generated during the dismantling of buildings. It is produced by crushing and sorting waste.

Meanwhile, the produced recycled aggregate can be used for cement concrete or subbase. At this time, in the case of recycled aggregate for cement concrete, the particle size range is narrow between 2.5 mm and 25 mm, so the particle size range can be easily adjusted using the recycled aggregate production method of producing single particle size.

However, in the case of recycled aggregate for subbase, the particle size range is very wide between 0.08㎜ and 75㎜, so the recycled aggregate production method of producing a single particle size cannot meet the particle size specified in the specifications, so 2 to 3 types of recycled aggregate by particle size (single particle size) are used. (Coarse aggregate, medium aggregate, fine aggregate, etc.) produced by is mixed and used according to the specifications.

Figure 1 shows a process diagram of a conventional method for producing recycled aggregate for a subbase.

Construction waste input into the recycled aggregate production equipment is crushed by sequentially passing through a jaw crusher, a double jaw crusher, and a cone crusher. The shredded construction waste has different checkers and is separated by particle size in the process of passing through screens arranged in a multi-stage structure. are selected.

In order to use the aggregate selected by particle size as recycled aggregate for the subbase, the mixing ratio is determined to meet the specifications and the recycled aggregate by particle size is mixed at a certain ratio.

Meanwhile, when mixing recycled aggregates of different particle sizes, a mixing method using the bucket capacity ratio of heavy equipment has been used conventionally.

For example, recycled aggregate produced in the particle size range of 8 mm to 40 mm is mixed with stone dust produced in the particle size range of 8 mm or less, and 200 to 300 parts by weight of stone dust of 8 mm or less is used for 100 parts by weight of recycled aggregate of 8 mm to 40 mm. When trying to produce recycled aggregate for subbase by mixing at a negative ratio, it is produced by mixing 2 to 3 buckets of stone dust of 8 mm or less with one bucket of 8 mm to 40 mm recycled aggregate. However, this method has a large error, so the mixed There is a problem in that particle size control frequently fails because the aggregate does not fall within the particle size range.

Another method is a method using a hopper and a belt feeder, and the concept of mixing recycled aggregate using a hopper and a belt feeder is disclosed in Figure 2.

This method mixes two types of recycled aggregate using the speed ratio of the belt feeders (21, 22), and places the belt feeders (21, 22) at the outlet of the hopper (11, 12) where the recycled aggregate by particle size is stored. The recycled aggregate discharged is transported to the mixing area, and the speed of the two belt feeders (21 and 22) is varied depending on the mixing ratio.

This method can adjust the particle size distribution more precisely than the method using buckets of heavy equipment, but it has the problem of requiring a lot of equipment cost because it requires the use of a hopper and belt feeder separately from the recycled aggregate production device.

Furthermore, in order to measure real-time transport volume on a belt conveyor that transports cement, etc. in bulk, a belt scale is mounted in the middle of the conveyor or a method of measuring it in a hopper at the discharge port at the end of the conveyor is used. did.

However, in this case as well, the expensive belt scale imposes a large economic burden, and weighing in a hopper at the end has the problem of being difficult to apply because the facility is complex and takes up a lot of space.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.

Referring to FIG. 3, the belt conveyor transport volume control system 100 according to this embodiment optimizes the front and rear mechanical facilities including the belt conveyor 101, which is transported from one side to the other with the cargo loaded on the upper surface. The control system 100 is equipped with a radar sensor unit 110, an operation processing unit 120, and a control unit 130 of a specific structure to detect the belt conveyor in real time and operate the mechanical equipment installed at the front and rear ends of the belt conveyor. It is possible to provide an optimal control system for front and rear mechanical equipment that can optimally control.

Hereinafter, each component constituting the optimal control system 100 for front and rear mechanical equipment according to this embodiment will be described in detail with reference to the drawings.

The radar sensor unit 110 according to this embodiment is mounted on the upper part of the belt conveyor 101 at a predetermined height in a direction perpendicular to the belt surface, and the height of the cargo loaded and transported on the belt surface is set to 80 GHz. After detection in real time using a high-band radar sensor, the detected data can be transmitted to the calculation processing unit 120.

At this time, the calculation processing unit 120 mounted on one side of the belt conveyor 101 calculates the weight of the cargo and the transport amount of the cargo based on the data obtained from the radar sensor unit 110, and then sends the calculation result to the control unit ( 130).

Specifically, the calculation processing unit 120 according to the present embodiment detects the loading height of the transported object 10, calculates the cross-sectional area of the transported object 10, multiplies the transport speed value of the belt and the specific gravity value of the transported object, and calculates the per hour Transport volume can be calculated.

In some cases, the front and rear mechanical equipment optimal control system 100 according to this embodiment may be configured to further include a physical state detection sensor.

Specifically, the physical state detection sensor is a component mounted adjacent to the radar sensor unit 110, and can detect the physical state of the transported object and transmit the detected data to the calculation processing unit 120. At this time, the calculation processing unit 120 may calculate the transport amount per hour of the transported object based on the data detected through the physical state detection sensor.

At this time, the physical state data detected from the above-mentioned physical state detection sensor is data regarding the moisture content of the transported material, particle size, loading condition (piece size), and degree of particulate matter scattering.

Additionally, the radar sensor unit 110 can detect the loading status of the transported object. Specifically, it is detected whether the loaded items are evenly and stably placed in the center or whether the loaded items are concentrated on one side.

Based on the data acquired through the calculation processing unit 120, the control unit 130 changes the load provided on the belt surface of the belt conveyor 101 or changes the mechanical equipment installed at the front and rear ends of the belt conveyor 1010.

For example, if the load provided on the belt surface of the belt conveyor 101 is less than the allowable amount of the mechanical equipment installed at the rear end, the load amount of the mechanical equipment installed at the front end is increased. On the other hand, if the load provided on the belt surface of the belt conveyor 101 exceeds the allowable amount of the mechanical equipment installed at the rear end, the load amount of the mechanical equipment installed at the front end is reduced.

At this time, a position fixing protrusion 104c is formed on the lower surface of the belt 104 to prevent lateral deviation of the belt, and a position fixing groove 105c may be formed on the roller 105 at a corresponding position.

The radar sensor unit 110 according to the present embodiment mentioned above preferably uses radar waves in the 80 GHz band that penetrate particulate matter floating in the air.

Laser radio waves in the 80 GHz band do not cause reflection by particulate matter floating in the air, such as dust, and can more accurately and effectively detect the target to be detected.

As shown in FIG. 3, the mounting position (L1) of the radar sensor 111 of the radar sensor unit 110 is compared to the entire belt length (L2) from the position where the cargo is loaded on the belt surface of the belt conveyor 101. It is preferable that the positions are spaced apart by 10 to 50% of the length. If the radar sensor unit 110 is installed too close to the position where the cargo is loaded on the belt surface of the belt conveyor 101, the cargo loaded on the belt surface may move or roll away before being placed in place, causing the location to change. The data cannot be detected accurately. Therefore, the position of the radar sensor unit 110 is applied within the above-mentioned range so that the data to be detected can be detected using the radar sensor unit 110 after the cargo loaded on the belt surface is in position to some extent. desirable.

Specifically, the radar sensor unit 110 may be configured to include a rail support unit 112, a sliding rail unit 113, and a position change driving unit 114 of a specific structure.

As shown in FIG. 4, the rail support unit 112 may have a structure that extends upward by a predetermined height from both sides of the belt of the belt conveyor 101 to support the sliding rail unit.

The sliding rail part 113 is a component mounted on the top of the rail support part 112, and has a rail structure extending a predetermined length in a direction parallel to the extension direction of the belt, so that the radar sensor 111 can be slid to change the position. It can be mounted.

The position change driving unit 114 can change the position of the radar sensor 111 mounted on the upper part of the sliding rail unit 113 according to a control signal from the control unit 130.

In this case, as mentioned above, it can be easily used when changing the position of the radar sensor unit 110 to more easily and accurately detect the transported object.

In addition, the physical state of the cargo may change depending on the work environment, the weather on the day of work, etc., and of course, the position of the radar sensor unit 110 can be changed to an optimal position accordingly.
