Abstract

The present invention discloses a work vehicle risk management system comprising: a detection tag carried by the guide; a sub-anchor placed on the work vehicle that transmits a detection signal when the detection tag is detected within a critical distance via near-field wireless communication; a main anchor placed on the work vehicle that receives the detection signal and outputs a first alarm indicating a collision risk and a separation distance; and a safety management server that collects location information of the worker and the work vehicle using signals transmitted and received between the detection tag, the sub-anchor, and the main anchor, including the detection signal. According to the present invention, workers, including the guide, can be protected from the causes of danger caused by the work vehicles at a site where multiple work vehicles are present.

Description

Construction Machinery Risk Management System and Method The present invention relates to a work vehicle risk management system and method, and more specifically, to a system and method for managing work vehicles, such as forklifts used in the field, to prevent safety accidents in advance. The contents presented in this section are intended merely to provide background information for the present invention and do not constitute prior art. Occupational Safety and Health Standards provide criteria for the placement of guides who direct construction machinery and the like as safety managers. A guide or signalman refers to a person who directs the movement of equipment and vehicles at or near the site when deemed necessary during a risk assessment. However, when there are multiple guides and work vehicles forming a team, accidents frequently occur in which the guide focuses their attention on the work vehicle they are managing, failing to recognize the approach of other work vehicles and colliding with them. As a technology related to the present invention, the intelligent heavy equipment safety remote control system disclosed in the Korean Registered Patent Publication discloses a system comprising a UWB tag for a worker, a UWB tag for heavy equipment, a facility UWB anchor and UWB tag, and an approach alarm module. While this related technology is limited to generating an alarm when the UWB tag for the worker approaches within a certain distance, the present invention is distinguished from the other invention in that it is a system that prevents collisions between work vehicles and guides belonging to different groups when a work vehicle and a guide form a group and multiple groups of work vehicles and guides exist within a workplace. FIG. 1 is a network relationship diagram of a work vehicle risk management system according to one embodiment of the present invention. Figure 2 is a block diagram of the main anchor depicted in Figure 1. Figure 3 is a block diagram of the safety management server depicted in Figure 1. FIG. 4 is a flowchart of a work vehicle risk management method according to one embodiment of the present invention. Before describing the present invention in detail, it should be understood that the terms and words used in this specification should not be interpreted as being limited to their ordinary or dictionary meanings, and that the inventor of the present invention may appropriately define and use the concepts of various terms to best describe their invention, and furthermore, that these terms and words should be interpreted in a meaning and concept consistent with the technical spirit of the present invention. In other words, it should be understood that the terms used in this specification are used merely to describe preferred embodiments of the present invention and are not intended to specifically limit the content of the present invention, and that these terms are defined in consideration of various possibilities of the present invention. In addition, it should be noted that in this specification, singular expressions may include plural expressions unless the context clearly indicates a different meaning, and that even if they are expressed in a similarly plural form, they may include the meaning of the singular. Throughout this specification, where it is stated that a component "includes" another component, unless specifically stated otherwise, this may mean that it does not exclude any other component but may include any other component. Furthermore, it should be noted that in cases where it is stated that a component "exists inside or is installed in connection with" another component, this component may be installed in direct connection or contact with the other component, or it may be installed at a certain distance apart, and in the case where it is installed at a certain distance apart, there may be a third component or means for fixing or connecting the component to the other component, and a description of this third component or means may be omitted. On the other hand, if it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there is no third component or means. Likewise, other expressions describing the relationship between each component, such as “between” and “right between”, or “adjacent to” and “directly adjacent to”, should be interpreted as having the same intent. In addition, it should be understood that in this specification, terms such as “one side,” “other side,” “one side,” “other side,” “first,” “second,” etc., are used to clearly distinguish one component from another component, and that the meaning of the component is not restricted by such terms. In addition, position-related terms such as "up," "down," "left," and "right" used in this specification should be understood as indicating the relative position of the corresponding component in the drawing, and unless an absolute position
