In general, the operator transmits the position tracking information and the safety loop information during the operation. In particular, the position tracking information attaches a sensor (MEMS pressure sensor, an altitude sensor) capable of acquiring environmental information to the transmitter of the operator and checks whether the worker moves. Adopted a sensor that can measure (3-axis acceleration sensor) is configured to determine whether the worker's movement.

By interlocking the MEMS sensor as described above, not only the worker's position information but also various environmental information around the worker can be obtained, thereby analyzing the environment information in a server and finally contributing to worker safety.

The location tracking information and the safety loop information can be obtained by dual configuration of the TOA-type wireless hardware and the RSSI-type wireless hardware. With the dual configuration as described above, the system is configured to separately transmit and receive the location tracking information and the safety loop information. It was. In other words, if this dual method is adopted, and the primary situation does not receive one of the location tracking information or the safety loop information due to the deterioration of the surrounding situation, it is possible to continuously receive the other information and analyze the worker's condition secondarily. To ensure that

The system of the present invention analyzes the safety collar information and the location tracking information of the worker in the workplace to check whether the safety equipment is worn when the worker enters the workplace in a dangerous area, and if it is determined that the safety equipment is not worn, the system is transmitted to the manager and the worker through the server computer. It is intended to have a function to prevent safety accidents by giving warnings and alarms.

In general, the conventional location tracking system for worker safety has been able to acquire the location tracking information by using the GPS and RSSI method, and in particular, whether or not to wear safety equipment such as worker hard hat by obtaining the information by RSSI method In the present invention, the TOA method is applied to differentiate the conventional method so that the location tracking information can be estimated without time synchronization between APs for collecting location tracking information, and the location tracking information is input in advance. It is configured to analyze risk information through the server and transmit it wirelessly to workers to wear safety equipment when working in hazardous areas.

To this end, an acceleration sensor and an altitude sensor (pressure sensor) for measuring environmental information are equipped to allow an administrator to accurately analyze a worker's position even when working at high altitudes.

In order to solve the above problems, the construction site is divided into a plurality of cells according to the size of the construction site and the surrounding conditions. A plurality of APs are installed in each cell, and the distance between the AP and the transmitter attached to the worker is measured, and also attached to the worker. When working at a certain height using one altitude sensor is configured to sound a warning alarm to determine the danger. Here, the number of APs installed to measure the distance from the transmitter attached to the operator is correct, but the number of APs installed here is taken as an example.

The system of the present invention calculates the distance to the operator by recognizing the transmitter T1 attached to the operator to transmit the position tracking information, the transmitter T2 attached to the operator to transmit the safety loop information, the safety loop information and the position tracking information The work site is divided into a plurality of areas, and a plurality of APs (wireless internet routers) composed of a plurality of cells capable of setting respective areas and worker information generated from the transmitters T1 and T2 are received to receive final location tracking information. And a base station that receives safety loop information, and the worker's location information and safety loop information connected to the base station and received from the transmitter, so that the worker works in a hazardous area without wearing safety gear or If you are in a regional location, alert administrators and workers It is connected to the server system and the server system characterized in that it comprises a display unit for displaying a warning alarm or the like.

In addition, the position tracking information of the present invention is characterized by using a triangulation method.

In addition, the plurality of AP of the present invention is characterized in that four or more.

In addition, the transmitters T1 and T2 of the present invention are configured in dual to receive location tracking information and safety ring information.

The system of the present invention can not only maximize the efficiency of the workplace through the safety management of workers at large and small workplaces in the country, but also has the effect of preventing accidents that may occur in the workplace by improving stability.

2 is a diagram showing a transmitter design worn by the operator of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a system according to the present invention.

The system of the present invention is basically divided into a transmitter and a receiver. The transmitter includes a transmitter T1 for tracking location tracking information and a transmitter T2 for transmitting safety loop information. Such a transmitter system includes a function of transmitting and receiving information wirelessly. The receiver system needs an AP that can set a location recognition area, and four are designed to form one cell as shown. The base station transmits and receives information of the transmitter and collects final location tracking information and safety loop information, and a management server analyzing the information.

As shown in the figure, the system of the present invention is installed in the workplace divided into four APs by dividing the workplace, if the worker is located in the workplace, and receives a signal generated from the transmitter attached to the operator, the distance between each AP is It is measured by triangulation. After measuring the distance between each AP, the server computer calculates the location tracking information based on the measured data, that is, the location tracking information and the safety loop information. Mark the location to identify the location. At this time, the AP is accurate if a large number of installation, but in the present invention, four examples are given. In other words, the signal generated from the worker transmitter is received from AP1 to AP4, the distance from the transmitter attached to the worker is calculated from each AP, and each boundary is marked so that a place where the signals received from the four APs overlap in common. It is recognized by the worker where he works. On the other hand, since the general workplace is often working on the ceiling, the outer wall, etc. than the floor surface in the present invention, it is possible to recognize the risk information of the worker working at a certain height by embedding the altitude sensor, if it is determined that the dangerous situation, Configure the alarm to sound.
