PERFORMANCE MANAGEMENT SYSTEM BASED ON SMART BRACELET

The utility model discloses a performance management system based on an intelligent bracelet, which belongs to the technical field of performance management and comprises the intelligent bracelet, a cloud server and a monitoring terminal. The intelligent wristband transmits vital sign information, monitored in real time, of the construction personnel to the cloud server; the cloud server judges whether each vital sub-sign parameter value is within an index range corresponding to the cloud server within the working time or not, and transmits an obtained first judgment result to the monitoring terminal; and the monitoring terminal executes a first performance management strategy according to the first judgment result. Monitoring vital sign information of the construction personnel through the smart wristband and transmitting the vital sign information to the cloud server, and determining performance of the construction personnel distributed in different intervals by the cloud server according to the received vital sign information; and the first judgment result is transmitted to the monitoring terminal, and the monitoring terminal executes a first performance management strategy according to the performance of different intervals. Therefore, the management effect of the construction industry is improved and the development of the construction industry is promoted.

One of the most important differences between this invention and the stated invention is that in this invention, the vital information of the workers is continuously transmitted to the server, and the project manager will give access to the project workers based on the tasks and job group, and in case of violation of any of the conditions, the relevant device will be turned off and an alert will be sent to the safety team.

An administrative wristband with sensors monitors workers and construction site information in real time, sending it to a server for processing. The wristband includes cameras, a GPS sensor, an altimeter, and an accelerometer. The data is used to analyze and check project progress. Additionally, the wristband includes a controller module, safety manager, and access control. The system also provides the user with the least risky and shortest path to reach the place of execution. A heart rate and temperature sensor, gas detection sensor, microphone, speaker sensor, and wristband charger base are included as well.

In most executive projects, the progress process is recorded manually and then entered into the relevant software by an operator, and due to various busy schedules and the need for manpower, these things are sometimes not done, which causes the project managers to not have accurate information about the physical progress of the project, and sometimes even the cases recorded by human resources have errors.

The workers' lack of knowledge about the high-risk environments of the project or the lack of visibility of the environment of the drivers of heavy machines will cause a stop and disruptions in the implementation process of the projects.

Failure to know the rules and safety tips related to any work or failure to comply with the conditions and rules of the construction site by the project staff, such as not having a helmet while doing the work, or lack of skill in working with a specific device and equipment will cause irreparable damage to the project.

One of the most common problems during the implementation of projects is the lack of accurate writing of the text by the supervisor and project workers due to the unavailability and lack of written conditions during the execution of the work, which causes various conflicts in evaluation and management. It becomes a project.

By using this wristband, all project employees can communicate with each other in the form of an integrated platform, and project managers can be informed about the exact execution process of the project and prevent possible injuries and damages by constantly checking the construction site’s conditions, which increases efficiency and reduces costs.

Solution of Problem

Project management is a process to achieve a considerable economical balance between three factors of cost, time, and quality during the execution of a project which gets help from special techniques and tools to do it.

The project management wristband is designed to improve the scope of project management and reduce the possible damages during it based on the Internet of things and artificial intelligence, and it will help managers as assistant-help to control the project better.

To examine the progress and safety of the process, this patent is divided into two parts administrative and executive. In the administrative part, it is required to enter the data carefully so the examination of the project’s process and safety inspection condition can be done accurately.

The administrative part is described as follows:

First, the project ground surveying is done by the surveying team, and a GIS map is inserted into the Revit software then the designing team will model the project in the software, after the modeling of the project, it is required to specify the details of each element (element name, type of element, definite weight and size, material, cost, designer’s identity, work break down structure) by using the designed plug-in for Revit software.

In the designed plug-in for Revit software, all the elements contain defined covering and structures which only demand the specification of structure and material. (to increase the speed of the process in the material designing section and structure of each element which is made for any family and object defined in the Revit software and defined in this amount by default, and will be applied if the designer needs changes. The exact location of each element is automatically put in that element’s detail.)

The executed samples of each element are thought to picture processing neural network (for example, concrete cover, plaster …) and the designed neural network identifies the executed elements coverings to analyze the project’s process percentage based on the accomplished physical work and it compares them with the final surfaces covering of the designed elements or element’s lower layers.

For example, an example of column A that is typed, its details are defined as follows {JSON object}:

A type column:

Size: 3* 0. 2*0. 2

The height from the ground floor of the project is 3 meters (second-floor column).

Material of the final body: Concrete

Project progress review conditions

If the building was not built, 0% progress

If the bars were built (rebar mesh) and the material was iron element, 35% progress

If it was molded and the material was the iron element, 55% progress

If the column concrete was poured and the element material was concrete, 80% progress

If the white work is done and the element material is plaster, 100% progress

Schedule (the duration of each section is determined based on the breakdown structure of the project's progress)

Start time: 5 October 2021

Required time for rebar weaving: 5 days

Duration of column shuttering: 3 days

Duration of concreting: 7 days

The required time for the skim coat column: is 2 days

The required time to execute each element: is 17 hours

The related occupational group to execute each element:

ordinary workers

safety examining condition (personal safety):

-The helmet is examined.

-The workwear is examined.

Safety tips (training):

-Put your helmet on.

-Put your workwear on.

Steel fixer:

safety examining condition (personal safety):

-The helmet is examined.

-The workwear is examined.

Safety tips (training):

-Put your helmet on.

-Put your workwear on.

-Put your gloves on.

Related workers to do this part:

-Name (ordinary worker) – ID number….

-Name (Steel fixer) – ID number….

-Name (Ordinary worker) – ID number…

Each element’s details of the project are entered in the designed plug-in as in the mentioned example, and similar elements are typed to increase the speed and make it easier.

To control the safety section of the workplace, some important elements and related safety conditions are defined permanently (these conditions are changeable by the executive team) and each person’s safety condition will be examined regularly using picture processing based on the defined conditions. Picture processing neural network (Corner Detection, Yolo, Open Cv) is thought based on the introduced elements in , and

As an example, the following conditions are defined for tower crane drivers and are examined regularly:

1- putting on a helmet

2- putting on a workwear

3- age under 40 years old

4- Workers should not use the device for more than 5 hours a day.

5- Only the related worker is allowed to turn on and off the related device.

6- If the height difference of the two tower cranes is less than 5 meters, first the alarm and then the devices must be turned off.

7- If the distance between the heavy machine driver and the worker is less than 5 meters, an alarm will be sent to the worker and the driver.

8- If the distance between the worker and dangerous areas is less than 3 meters, an alarm must be sent.

At the beginning of the day, the project members hold their fingerprints on the charger’s base or stand in front of the wristband’s camera, the magnetic lock of the wristband is opened, and pick up the wristband from the charger’s base to wear it and then, the camera number 1 will be examined the safety condition of the person based on the defined conditions, then the related activities will be displayed on its screen and the system will suggest the shortest or the least dangerous path to go to the workplace based on the ant colony optimization algorithm, if the worker gets close to the dangerous areas or heavy vehicles, the wrist band will be vibrating. To execute the defined safety conditions in the administrative section, the controller module will be installed on all of the electric devices and construction machines.

Camera number 2 pictures the whole people at the construction site, elements of the project, and other environmental factors, and sends them to the server. Also, camera number 2 is sensitive to fire and deep surface dips so it will send them to the settled team ON the construction site after spotting them. To analyze all the elements, if an element is not evaluated after a certain period, the route suggestion system suggests routes where the information of those elements can be received by the project members.

After the worker reaches the specified area, it is necessary to press the button to start the activity and while doing the work, the wristband records the heart rate, body temperature, number of steps, hours of inactivity of the worker, and geographical location of the worker and according to the defined conditions and wristband sensors, all safety related parameters are continuously checked, and if the points are not followed, his activity will not be calculated, and after 5 minutes, if the points are not followed, an alert will be sent to the safety team settled on the construction site, then the wristband will start to vibrate.

After the work is completed by the worker, based on the defined breakdown structure of each section, the checklist related to the performance of that activity is displayed to the worker, and the corresponding worker selects the completed options based on the completed tasks, and then uploads one or more photos of the work done and, if needed, it records explanations in audio format and uploads them to the system.

Workers and members of the project while doing daily work, can record their report by holding the answer button, additionally, all project stakeholders will be able to create discussion groups with different accesses in a unified platform and create in-line with the project and discuss with each other that all these correspondences and reports will be stored in the system. The communication method of all the project people will be through this wristband and the information of the wristbands will communicate with the cloud server through the 3G, 4G, 5G network or the internal WIFI network. To reduce errors in communication interruption Wristband with the cloud server, the information is stored on the external memory, and after connecting to the first network, the information is sent and the information on the external memory is deleted.

According to the defined access, the project members can access the project documents (executive plan, schedule, information on each element, etc.) Reduce the project and focus more on work.

All this information will be recorded in the system and the project managers can use this information to provide a more accurate and appropriate plan for future projects, and they will also be informed online about the amount of progress and the entered results.

According to the defined access, the project members can access the project documents (executive plan, schedule, information of each element, etc.) and it minimizes the things that workers and spectators should have with them so they can focus more on their work.

Moreover, other systems such as salary systems, insurance, and other systems can access system information through API. It should be noted that all this information will be uploaded to cloud servers.

Element’s processing is employed for a more specific calculation of the percentage of the project’s progress in addition to workers announcing their fulfilled tasks. Calculation of the progress percentage of each element of the project is received from the project members' receiver camera during the day and their passage through the project’s related routes.

To identify each element, first the picture, time, location of each person (RTK GPS), and height from the project’s surface are sent to the server. Then, the details in each picture are recognized by picture processing algorithms and artificial intelligence (Yolo, Open CVl, Neural Network), and finally, their center is pointed by using RTK GPS and Photogrammetry technique (Resection) and wor sensor’s data, the location of each element’s center in the picture is identified, then the percentage of each element’s physical progress is calculated based on elements’ defined location in technical maps (Output of Revit’s plug-in) and processing the covering, each element’s material and equivalent of the received information of the executed elements with technical map’s elements according to the defined rules.

It is demanded that at least 3 pictures of each element from 3 people be sent to the server in less than 3 hours. After averaging the received numbers, if the distance between the averaged calculated numbers is more than 5 percent, the number that has the highest distance is deleted. It is necessary to say, that the announced progress percentage by the worker and the calculated progress percentage in different lines are stored in the system, and if the announced percentage difference is more than 10 percent, this case sends a warning to the executive and administrative team so it gets examined accurately.

Senior managers of the project and safety section managers can implement the system’s output online such as fulfilled activities percentage, workers’ safety condition, location of each, and other important information to make administrative decisions.

The project manager can specify the number of processing each element during the day to increase the system’s function. For example, each element is examined 3 times a day. Also, the project manager can define some servers to increase the processing power of the system, and then define the related server for processing each worker’s information. Also, the project manager can modify the program to receive and process pictures from the wristband every 30 seconds.

Because the system is Android, spectators and engineers can install this system on their devices and use it. Furthermore, the designed software is installed on every set’s cloud servers which makes it available for other devices such as laptops, tablets, and smartphones to have access to this information and make some changes according to their level of accessibility.

is a flow chart for the administrative and safety section: After surveying the construction site, they will be inserted in the Revit software to be modeled and defined as conditions of the project and safety, occupational group, etc... Then, they will be uploaded into the system and if the system gets updated, this process will be repeated.

is a flow chart of the executive section: First, the lists of daily tasks are shown then the safety ones and their tips, the worker must be present at the construction site to begin the work so the device measures heart rate, body temperature, steps, etc..., after finishing the tasks, the workers submits them to the system so the project's progress will be calculated.

is a flowchart showing that the information received from the user’s wristbands is stored in the servers and then processed in the cloud servers.

Examples

By using this wristband, project management of construction sites will be easier and the security will increase. This wristband is used in construction sites and workshops, public and private organizations, etc., for example:

-Project managers can define specific safety standards for tower crane drivers, for example, if the total working hours of the worker exceeds 5 hours, the automatic device will be turned off, and if the height of the adjacent tower crane is less than 7 meters, the bracelet will start to vibrate. The device should be turned off if it is less than 5 meters.

-To increase personal safety, at the beginning of the day after workers enter the construction site, safety tips are displayed on the wristband display, and at the end, it is necessary to hold the confirmation button after the image processing operation and check compliance with safety tips, the worker is allowed it will take the entrance to the construction site.

[Table. 1] displays the safety equipment the wristband wants the users to wear during the project.

[Table. 2] displays the elements and objects defined in the designed plug-in for Revit software and picture processing neural network.

When a worker gets on the crane, he needs to click the start button on his wristband, and the machine can no longer be turned on and off using a switch or key.

The project managers must enter the project specifications and information in the system and then explain the construction site’s tasks based on this and determine the conditions for the analysis of each part, which can complete the projects more quickly and safely. This wristband helps managers view the current information of the project in an integrated and real-time manner and make decisions accordingly.

By using this wristband, workers are informed of their duties at the beginning of the day, and during work, the defined individual safety conditions are continuously checked, and at the end of the work, after pressing the end of work button, the end of the activity is recorded, and then on Based on the information received from camera number 2 of some people present in the system processing environment, the implemented activity will be carried out.

Project managers can define conditions based on built-in sensors to have more precise control over workers, for example, they can define conditions for drivers and workers if workers do not have helmets or glasses first. An alarm will be given to the driver and if they do not comply, their working hours will not be calculated and the bracelet will start to vibrate. After 5 minutes, an alert is sent to the safety team located at the construction site.

For example, the project safety manager can define the following conditions for the active groups in the project:

-Electrical and telecommunication workers: checking helmets, gloves, and safety shoes

-Welder and welder's assistant: examination of safety helmets and shoes, welding glasses

-Mining worker or well digger: Check helmet, rubber gloves, safety belt equipped with rescue rope

-Mechanical worker: Checking the lathe glasses, leather gloves, safety shoes
