Description

Construction site data collection system using wireless devices

The present invention relates to a construction site data collection system using a wireless device.

Recently, a variety of techniques for tracking the location and movement path of an object as well as authentication by attaching a tag to an object have been used. This is to increase the efficiency of management and management by tracking the flow of inventory management, logistics, and construction equipment. In particular, since the tag attached to the transfer object performs wireless communication between the mobile node and the fixed node without a separate action for recognition and the recognition and location tracking are performed in real time, its utility can be said to be very wide.

On the other hand, the wireless recognition technology is widely used as a person's ID card in the form of an RFID tag. For example, in the form of a card or tag, it is applied to employee cards, resident cards, and train passes. These ID cards are mainly used for access authentication or use rights, and have many advantages that existing magnetic cards do not have.

As such, the use of wireless recognition technology is expected to expand further because of its fast recognition speed and great user convenience. However, the existing technologies used as authentication tags are mainly installed at gates or entrances to controlled areas and are limitedly applied only to authentication of access. For example, there is no follow-up management after an employee or operator is authenticated at the entrance and passed. Therefore, it is necessary to introduce more effective wireless recognition technology for accurate cost calculation and efficient process management.

By allowing the worker to carry the wireless recognition unit, it is possible to identify the working status of each worker as well as to authenticate the identity for access. This makes it possible to calculate very accurate labor costs for some types of work. In particular, this is the case for workplaces that require a lot of manpower, such as a construction site, but require external manpower for each work area or type of work.

Wireless recognition devices used in construction sites may include beacons, worker's smart phones, separate personal terminal devices, and the like.

As a prior art, Korean Patent Registration No. 10-1884309, 'a system and method for providing a construction site management service using a beacon' is disclosed. The prior art discloses the contents of collecting the work history of the worker using a beacon and CCTV, generating a work report, and providing safety information to the worker.

As another prior art, Korean Patent Application Laid-Open No. 10-2016-0112048, 'a construction industry site safety management system using a beacon' is disclosed. In the prior art, a beacon is attached to a helmet, and it is possible to quickly and easily enter the site entrance gate when going to work, and it is possible to check whether access is permitted when entering a hazardous area, and if there is no movement of the helmet, status information is sent to the site manager It is transmitted immediately, and if the position of the helmet does not move according to time or the position of the helmet is shifted for a certain period of time, a system that can immediately transmit the status to the site manager is initiated.

However, the prior art is focused only on using the reception of the beacon signal in confirming the position of the worker, but it is insufficient to confirm all the information about the worker only with the beacon in a wide construction site.

In addition, in recent construction sites, although many materials and construction equipment are used in addition to workers (labor workers), it is very difficult to grasp accurate information about them, and most construction sites still process a lot of information manually. am.

Accordingly, in recent years, a technology for accurately collecting information about workers, materials, and construction equipment using various wireless devices and wireless networks at construction sites, and automating the process of collecting such information is required. there is a situation. In addition, many construction companies are now increasingly interested in technology for accurately estimating the standard construction cost, and ultimately, a technology capable of accurately estimating the standard construction cost using the information on the construction site is required.

Hereinafter, a construction site data collection system according to the present invention will be described with reference to the drawings. Terms used below are defined as follows.

'Worker' means a laborer who performs preset work within a construction site. 'Material' means construction materials used at the construction site, and it is explained on the premise that they are in a state of being separated by a preset unit, and the quantity can be divided in a box unit or a pallet unit. 'Construction equipment' is used in a comprehensive sense that includes all construction equipment used at the construction site. can be divided into

Construction site data collection system

A construction site data collection system according to the present invention will be described with reference to FIGS. 1 and 2 .

The present invention includes a beacon 100 , a tracker 200 , a repeater 300 , a network server 400 , and a central processing server 500 . 1 schematically shows two paths through which beacon information is transmitted to the network server 400 and the central processing server 500 . The first path is a path through the repeater 300 through the tracker 200, and the second path is a path through the mobile communication network base station through the LTE router.

Hereinafter, the first path will be described as a reference, but the second path will be described first. The second route assumes that the worker has a personal mobile device (smartphone, smart tablet, etc.). That is, without possessing a separate tracker 200, using a personal mobile device (not shown), worker access information, tower crane operation data, heavy equipment operation information, ready-mixed concrete operation information, etc. are provided to the network server 400 and the central processing server It can be passed to (500). At this time, the tower crane, heavy equipment, and ready-mixed concrete driver corresponds to the case of possessing a personal mobile device, and by using their personal mobile device, the information acquired through the LTE network, which is an external network, is transmitted to the network server 400 . am.

The beacon 100 may be provided at a preset location, material, and construction equipment within the construction site, and each of them is configured to transmit beacon information including the beacon ID in a state in which a unique beacon ID is assigned. The beacon 100 is configured to be wirelessly connected to the tracker 200 to be described later in a Bluetooth Low Energy (BLE) method. The beacon 100 transmits beacon information in the above-described BLE method, and the beacon information may not be transmitted to the tracker 200 at a relatively long distance, and is omni-directional, so that the tracker 200 at a short distance Beacon information can be transmitted. At this time, the tracker 200 may determine the beacon information signal strength transmitted from the beacon 100. In general, the closer the distance between the beacon 100 and the tracker 200, the greater the beacon information signal strength. It can be passed as a value (although it may depend on the location of the obstacle, of course). In addition, the beacon information transmitted from the beacon 100 may further include information on the amount of power of the beacon 100 . That is, it means information about the state of the battery built into the beacon 100 . The tracker information transmitted from the tracker 200 may include both information on the amount of power of the beacon 100 and information on the amount of power and charging of the tracker 200 . For reference, the power supply of the beacon 100 is usually maintained for more than 2 years, and the power supply of the tracker 200 is maintained for about 48 hours.

It is assumed that the construction site described in this specification is a construction site of a collective building. In the so-called apartment construction site, it is preferable that a plurality of beacons 100 are provided for each household. The location of the beacon 100 in each household may be located inside the wall pad, and may be buried together when concrete is poured inside each household. Mainly, by placing the beacon 100 embedded in the wall located in the center of each household, it is preferable to arrange the beacon 100 and the tracker 200 so that the worker can receive it at least at any location within a specific household.

Usually, the battery life built into the beacon 100 is about 2 years, and the above period can cover all construction stages. As described above, each beacon 100 is given a unique beacon ID. In order to distinguish the positions of a plurality of beacons 100, these beacon IDs need to be stored and managed in the labor management module 510 in advance. there is This process is preferably performed collectively through a separate beacon ID granting device.

The beacon 100 may be divided into a unit household location beacon, an entry/exit location beacon, an elevator hall location beacon, a basement location beacon, and the like, based on the installation location in the collective building. As described above, a unit household location beacon means a beacon installed in each individual unit household (meaning it is embedded in a wall pad or a wall located in the center of each household), and the entrance location beacon is the entrance/exit location on the first floor of each building. It means a beacon installed on the side.

Here, 'entrance' means the hoist entrance arranged in each building. It is common for workers, construction equipment, and materials to move using a hoist, and after the hoist entrance, it is linked with the elevator hall location beacon so that their movement can be identified. However, according to the designer's or manager's choice, it is specified that it can be arranged in a location adjacent to the hoist entrance. The hoist entrance may be located separately from the east entrance, and the east entrance may have a structure connected to the stairwell. At this time, a separate tracker may be provided at the entrance to the east.

The elevator hall location beacon means a beacon installed on each floor of the elevator hall. Here, in addition to the elevator hall location beacon, a separate beacon may be provided in the middle of the stairway connecting each floor. Workers frequently move through the stairwell, and if the distance between the stairwell and the elevator hall is relatively long, it may be difficult to check the movement of the workers moving to the stairwell. It may be provided for each stairway connecting the floors (meaning that it is provided in the middle of each floor).

A basement location beacon means a beacon installed in the basement or underground parking lot.

Here, one basement location beacon may be disposed in each preset area within the basement floor, and it is important to arrange them so that a blind spot in which a signal of beacon information generated from an individual basement location beacon is not received is not generated. The basement location beacon can also be embedded in the floor or ceiling of the basement (it can also be installed on columns, beams, etc. arranged in the basement).

The tracker 200 is a personal terminal configured to be able to receive beacon information transmitted from the beacon 100 in a nearby location. The tracker 200, like the beacon 100, is also paid to individual workers in a state in which a unique tracker ID is assigned. The tracker 200 generates tracker information based on the beacon information. That is, tracker information having a preset data structure is generated by collecting beacon information, and this tracker information is transmitted to the repeater 300 .

When describing the communication method of the tracker 200, the tracker 200 is wirelessly connected to the beacon 100 and the BLE method and is configured to receive beacon information from the beacon 100 located at a close distance, respectively. Unlike this, it is connected to the repeater 300 in a low power wide-area (LPWA) method and is configured to transmit tracker information to the repeater 300 . In this case, the tracker 200 and the repeater 300 may be connected in a LoRa network, Wi-Sun, or WAN method. That is, the tracker 200 and the beacon 100 are different in terms of functionality. Specifically, the tracker 200, unlike the beacon 100, further includes a GPS sensor module 260, a gyro sensor module 270, an emergency call button 280, and the like, and reconfigures the received beacon information (or reprocessing) and transmitting to the repeater 300 is included.

The tracker 200 may be conceptually divided into three broad categories. First, the tracker for the worker (200c) possessed by the worker, the tracker for the equipment provided in the construction equipment itself (200b), the tracker for the driver (200a) possessed by the driver who drives the construction equipment, and fixed installed at a preset position It is divided into a tracker (200d) for the dragon. Here, the fixed tracker (200d), for example, may be located on the hoist side of each building, and when the material is moved to a specific entrance by the fixed tracker (200d), it is possible to grasp the movement information of the material. The tracker 200b for equipment is typically a tracker mounted on a forklift, and in order to grasp the material loaded in a state fixed to the pallet on the fork of the forklift, it may be provided at a position adjacent to the fork. there is. In addition, if necessary, the tower crane may also be equipped with a tracker at a specific location.

On the other hand, the tracker 200, unlike the beacon 100, may require a separate power supply. Power supply may be performed in real time, or may be performed periodically. Specifically, the fixed tracker (200d) provided in the hoist can be stably configured to receive power from the hoist. It is preferable that the tracker 200b for equipment mounted on construction equipment including a tower crane or forklift is electrically connected to the construction equipment to receive power from the construction equipment. If, the tracker for equipment (200b) is difficult to supply power from the construction equipment, the tracker for the driver (200a) can replace the role of the tracker for equipment (200b). That is, when identifying the movement of construction equipment, the tracker information transmitted from the equipment tracker 200b is primarily used, but when the power of the equipment tracker 200b is not sufficient, the operator of the construction equipment It may be configured to use the tracker information transmitted from the identified driver's tracker (200a).

Referring to FIG. 3 , the internal configuration of the tracker 200 will be described.

The tracker 200 includes a signal receiving module 210 , an arithmetic processing module 230 , a signal transmitting module 250 , a GPS sensor module 260 , and a gyro sensor module 270 .

The signal receiving module 210 performs a function of receiving beacon information transmitted from the beacon 100 . As described above, the signal receiving module 210 is configured to receive beacon information in a BLE manner. The signal receiving module 210 is configured to receive the beacon information from the beacon 100 in a period of a first preset time, and in one embodiment, is configured to receive the beacon information in a period of 20 seconds. Of course, when the tracker 200 is not adjacent to the beacon 100, there may be a section in which the beacon information cannot be received. In order to prevent this, it is preferable to be installed as a whole at the construction site of the beacon 100 . In addition, when the signal receiving module 210 does not receive the beacon information, it is preferably configured to receive the GPS information. That is, the beacon information or the GPS information may be received by the regular signal receiving module 210 .

The operation processing module 230 performs a function of generating or converting tracker information based on the beacon information. The arithmetic processing module 230 is configured to receive beacon information from the signal receiving module 210, and processes the beacon information in a preset manner, thereby generating tracker information. In this regard, a plurality of trackers 200 may be located at a construction site where the construction site data collection system according to the present invention is used, and all information sensed or received by each tracker 200 is transmitted to the repeater 300 . In the case of transmission, an overload problem may occur in the repeater 300 and the network server 400 . Accordingly, the tracker 200 of the present invention is processed to have a specific data structure, and then is transmitted to the repeater 300 . At this time, the specific data structure is configured in the form of TLV (Time, Length, Value) and has a size less than a preset size (preferably less than 50 bytes), and the specific data structure consists only of information optimized for the construction site.

The signal transmission module 250 means a communication module that receives the tracker information converted by the operation processing module 230 and transmits it to the repeater 300 . At this time, the signal transmission module 250 is set to transmit the tracker information switched to the repeater 300 at a second preset period of time, preferably, it can be configured to transmit the tracker information in a period of 2 minutes. there is.

When described with reference to the foregoing, the tracker 200 receives beacon information by the signal receiving module 210 at intervals of 20 seconds, all of which are collected by the arithmetic processing module 230 . When 6 beacon information is collected over 2 minutes, the tracker information having the TLV data structure is transmitted to the repeater 300 . For convenience of explanation, the first time is 20 seconds and the second time is 2 minutes, as an example, but the first and second times may be changed to an optimal value according to the designer's selection and needs is to specify

The GPS sensor module 260 performs outdoor positioning of the tracker 200 at a preset third time period, and transmits the GPS information of the tracker 200 to the calculation processing module 230 at a preset second time period. is configured to This is because the location where the beacon signal is not received is highly likely to be outside, and GPS information may be received from outside. Specifically, the GPS sensor module 260 performs outdoor positioning of the tracker 200 at a third time period, and transmits GPS information to the calculation processing module 230 . At this time, the third time may be formed to be the same as the first time in the beacon 100 described above, but may be formed differently from the first time, which may be optimally set according to the selection of a designer or manager. can

The gyro sensor module 270 is configured to sense motion information of the tracker 200 . Here, the exercise information refers to the overall exercise. Representatively, the step information of the operator may be calculated using the gyro sensor module 270 . If the step information (meaning the step) is not 0, it means that the current operator is moving. When the step information is 0, it means that the current operator is not moving, and there is a possibility that the operator's safety abnormal situation has occurred. A separate call module (not shown) may be built in the tracker 200, and through the call module, the manager can make an emergency call with the operator in the above situation. In addition, it may be configured to provide an alarm or a notice to the manager.

In addition, the tracker 200 further includes an emergency call button. The emergency call button is configured to be operable by the operator in possession, and when the operator presses the emergency call button, the operator's tracker information is configured to be transmitted to the repeater 300 immediately. As described above, the default setting is that the tracker information is collected at a first time period and transmitted to the repeater 300 at a second time period. By manipulating it, it can be used as a means of notifying the manager of an emergency situation. Through this, the manager can determine the current worker's location and then check the worker's structure and safety status. That is, it performs a function of immediately and forcibly transmitting the tracker information transmitted to the repeater 300 to the repeater 300 in a second period of time.

On the other hand, the specifications of the tracker 200 that can be used in the present invention are as follows.

The repeater 300 of the present invention constitutes a LoRa network. The repeater 300 is also called a 'gateway' or a 'scanner', and performs a function of receiving tracker information and transmitting it to the network server 400 . The repeater 300 may be configured in a Wi-SUN, WAN network method in addition to the tracker 200 and LoRa method.

The network server 400 is configured to receive tracker information from the repeater 300 through a wireless network, and includes a database 420 that stores the received tracker information. The network server 400 performs a function similar to an NMS server (Network Management System Server) provided by an external communication network operator. The network server 400 may manage the presence or absence of abnormalities of the beacon 100 , the tracker 200 , and the repeater 300 . This is configured to determine whether there is an abnormality using the received tracker information. In addition, the network server 400 performs a function of performing validation of the transmitted tracker information. If the structure of the tracker information is delivered in a broken state or an error, these are not delivered to the central processing server 500, but are judged as 'abnormal', and only meaningful and normal tracker information is delivered to the central processing server 500 do.

The central processing server 500 performs overall analysis or calculation related to the construction site using the transmitted tracker information. The central processing server 500 is connected to the database 420 included in the network server 400 and performs an operation in a predetermined manner on the tracker information stored in the database 420 .

The central processing server 500 includes a labor management module 510 , a material management module 530 , and an equipment management module 550 . The labor management module 510, the material management module 530, and the equipment management module 550 load one or more tracker information stored in the database 420 in a preset manner, respectively, but the beacon ID and beacon information By processing the tracker information including the number of receptions in a predetermined manner, it is configured to provide divided labor data, material data and equipment data.

The labor management module 510 , the material management module 530 , and the equipment management module 550 are all processed using tracker information, and the details provided are as follows.

The labor management module 510 provides detailed information on the number of dispatched workers by company, work type, team, and job type, aggregates the worker commuting status and input productivity, and provides worker movement information. It is possible to check the high-risk input history of workers and the time spent in each moving location (individual households, basement floors, stair floors, etc.)

The material management module 530 manages invoice management and material loading and consumption. Invoice management is performed by invoice registration and invoice material mapping monitoring, and material loading and consumption management is performed by material arrangement management, inventory management, incoming invoice detail management, ready-mixed concrete pouring plan and status monitoring.

The equipment management module 550 performs on-site equipment status management and equipment usage status monitoring functions. Site equipment status management separates paid and paid construction equipment and manages construction equipment usage status monitoring mainly manages the use of tower cranes and forklifts.

Tracker information processing process in central processing server

A process of processing tracker information in the central processing server 500 will be described with reference to FIGS. 3 to 5 .

As described above, the tracker 200 of the present invention receives a beacon signal from the beacon 100 at a cycle of 20 seconds, and transmits tracker information at a cycle of 2 minutes. If one cycle is 2 minutes, a total of 6 beacon information is collected, and the collected 6 beacon information is converted into tracker information and sent to the central processing server 500 .

Referring to FIG. 5 first, the worker is currently performing work in room number 1011. Since the signal of beacon information is transmitted in the BLE method, it is difficult to be transmitted in a vertical direction, but there is a possibility that it is transmitted in an adjacent horizontal direction. That is, it means that the beacon information of the beacons 1012 , 1013 , and 1014 of the beacons 1012 , 1013 , and 1014 can be transmitted to the worker 1011 . Of course, the operator of No. 1011 will have the largest beacon information signal strength transmitted from the closest beacon 1011 of No. 1011.

When the operation processing module 230 of the tracker 200 performs beacon information having different beacon IDs from a plurality of beacons at the same time, among them, the beacon information having the largest beacon ID signal strength of beacon information is used as a representative value. decide After performing this process a total of 6 times at intervals of 20 seconds, the tracker information is transmitted to the repeater 300 through the signal transmission module 250 .

4, the central processing server 500, when the tracker information includes a combination of beacon information having at least two or more different beacon IDs, the beacon ID with the highest frequency among beacon information having different beacon IDs. Beacon information is determined as a representative value. In the case of FIG. 4, the tracker information consists of a total of 6 beacon information, 4 beacon 1, 1 beacon 2, and 1 beacon 3. The tracker information determines the beacon information of the beacon ID, which has the highest frequency in the central processing server 500, as a representative value, where beacon 1 is determined as the representative value.

Interpreting the above result, it is calculated that the worker with a specific tracker ID stayed in the space where the beacon 1 101 is located for 2 minutes. The tracker 200 continuously repeats this process, and uses not only the worker in the construction site, but also the material and It is also possible to check the movement of construction equipment. That is, it is not the principle of sensing the location in real time, but the principle of estimating the movement inversely using the beacon 100 , the tracker 200 and the central processing server 500 . In this way, it is possible to solve the inaccuracy of calculation, which is a problem in the conventional method that relies only on GPS signals.

On the other hand, the GPS sensor module 260 performs outdoor positioning of the tracker 200 at a preset third time period (eg, 20 seconds), and provides GPS information of the tracker 200 to the calculation processing module 230 . to convey Under normal circumstances, the tracker 200 is configured to alternatively receive beacon information or GPS information. It should be noted that the alternative meaning here only means that it is selectively determined according to the position of the tracker 200, and does not mean that the operator selects. When the tracker 200 is located outdoors and the beacon 100 does not exist in an adjacent position, GPS information is received every 20 seconds. It can be seen that this applies when the worker performs outdoor work. Contrary to this, when the tracker 200 is located indoors, a GPS signal cannot be transmitted and received. In this case, the location of the tracker 200 can be determined from the beacon 100 .

Calculation processing module 230, when switching to tracker information at a period of a preset second time (2 minutes), when GPS information and beacon information are acquired at the same time, converts only beacon information to tracker information to repeater 300 send to That is, the beacon information takes precedence over the GPS information, and the beacon information is more trusted than the GPS information.

Device registration module process

The device registration module 570 of the present invention will be described with reference to FIG. 2 . The process performed in the device registration module 570 needs to precede the processes in the labor management module 510 , the material management module 530 , and the equipment management module 550 to be described later. The device registered in the device registration module 570 includes all of the beacon 100 , the tracker 200 , and the repeater 300 . That is, the term 'device' used herein is a concept distinct from the aforementioned 'construction equipment', and means devices for transmitting and receiving information, such as the beacon 100, the tracker 200, and the repeater 300. .

Information about the beacon 100 having a unique beacon ID and the tracker 200 having a unique tracker ID are both input to the device registration module 570 . For input, information about the beacon 100 , the tracker 200 , and the repeater 300 may be input using a PC and a notebook computer or a mobile device (smartphone, tablet) connected to the device registration module 570 .

Specifically, it is input at which location (household, entrance, elevator hall, specific part of construction equipment, etc.) the beacon 100 having a specific beacon ID is installed. In addition, after the beacon 100 is installed, it may be configured to register a location with a mobile device, and the mobile device and the corresponding beacon 100 are wirelessly connected in a BLE method, so that information on the beacon 100 is transmitted to the mobile device. may be transmitted to the device registration module 570 through

In addition, the beacon 100 may be configured to be activated through a connection with a mobile device carried by the worker. That is, it means that the beacon 100 is set not to transmit beacon information before, but is configured to transmit beacon information from this time by activation processing by the operator.

On the other hand, all beacons 100 attached to the above-described materials, construction equipment, tower cranes and hoists, etc., the location registration of the beacon 100 is performed in the above-described manner. At this time, the device registration module 570 may be divided into sub-categories according to the location where the beacon 100 is installed. That is, the manager may inquire only the information on the beacon 100 disposed in each household, or may select and inquire only the information on the beacon 100 attached to the material.

Process of labor management module

The provision of labor data by the labor management module 510 of the present invention will be described.

In addition, it performs the function of interworking with an existing system. In order to provide labor data, it is preferable for each worker to work with the tracker 200 attached to the helmet.

The collection of tracker information for the labor management module 510 is premised on the following process.

First, the beacon 100 is installed for each location. Beacons are installed in the order of unit household, stairway, basement, east entrance, hoist, and gang form. For unit household, stairway, and basement beacons, the mobile app is used to map building, floor, room, and area information and location.

An embodiment of the tracking process of the worker by the labor management module will be described with reference to FIG. 6 and Table 1 below.

In relation to the attendance management of workers, if the worker passes the biometric authentication system installed at the entrance and exit of the construction site after biometric verification of the new worker and the delivery and mapping of the tracker, the attendance information is checked through biometric authentication (access authentication). Here, as an example of biometric authentication, iris recognition may be used.

In relation to the work management of the workers, the location monitoring of the workers is performed by using the collection of beacon information and tracker information received through the LoRa network built during the movement of unit households, stairs, and basement floors, and when working.

Worker's leave management is the opposite of attendance management, and after releasing biometric identification and tracker mapping, the tracker is retrieved, and this process is configured to be monitored.

Referring to FIG. 7 , the roles of the beacon 100 and the tracker 200 will be described, for example, until the worker performs the work in the individual household of the collective building.

A worker equipped with a tracker 200 assigned a unique tracker ID enters the hoist entrance, and in the process of getting on and off the hoist, sequentially from the elevator hall location beacons (1001, 1002, 1003, 1004, 1005) of each floor to receive beacon information. As a modification, a separate tracker 200 may be provided inside the hoist, and it is possible to clearly determine whether the hoist is raised or lowered through the tracker 200 provided inside the hoist. When an operator gets off the 5th floor and enters an individual household on the 5th floor, by receiving beacon information from a beacon located in the individual household, the movement of the operator can be accurately calculated.

As another modification, a tracker is provided inside the hoist, and a location beacon may be installed at the front door and the rear door of the hoist, respectively. By the location beacon, it is possible to clearly determine whether to get on or off and the stay time. The tracker located inside the hoist is configured to receive beacon information from the elevator hall location beacon, so that it can be more clearly determined on which floor the hoist is stopped. At this time, the tracker 200 provided inside the hoist may be configured to receive a wireless signal when the front door and the rear door of the hoist are open. Through this, it is possible to calculate the exact time the operator stayed on the hoist.

Process of material management module

Review the interference in the yard to minimize the interference through the preliminary review of the yard location. When reviewing the import plan, check the required materials in connection with BIM, order and review defective materials.

Invoice management manages material import through the intelligent AI OCR scan method, and separates it into ready-mixed concrete, rebar, and general invoices in consideration of the characteristics of each material. The management of the yard is separately managed by installing beacons on materials with high material importance and frequency, such as pallets.

Material beacon management inputs key information such as material information, invoice information, and location.

Inventory management uses a mobile app to check real-time quantity and transmits to the server, and ready-mixed concrete management utilizes the ready-mixed concrete drivers' mobile devices (eg, smartphones), and checks real-time ready-mixed concrete status information throughout the entire pouring process. The pour management process can consist of pre-preparation, shipping, warehousing, pouring, and completion.

The rebar management utilizes an accumulator to compare the weight specified in the invoice of the rebars brought in and the actual measured weight, review the reliability of the rebar volume being imported, manage the volume of rebars by using the tower crane control system, and control the amount of rebar consumed. review the reliability of
