Description

Excavator management method and system {Method and system for managing the excavator}

The present invention relates to a method and system for managing an excavator, and more particularly, to a method and system for managing an excavator for preventing accidents due to undeclared excavation work by checking the position of the excavator.

The social and economic impact of the Daegu subway gas explosion in 1995, which caused a large number of human and property damage, had a significant social and economic impact, so safety management measures were established for underground facilities. However, large and small underground facility accidents are repeated every year. Inadequate management of underground facilities (pipes) such as damage to old pipes may also be the cause of these underground facility accidents, but most of them are caused by excavator construction. In order to prevent underground piping accidents due to excavation work, the current gas piping management is to be managed by one safety officer per 15km. Those who intend to carry out excavation works such as digging, new construction, and demolition of buildings, report in advance, and the law requires that the construction be carried out in the presence of the safety management officer. As a result, the number of reports of excavation work in 2018 increased by 0.5% from the previous year to 229,000, which seems to have entered the settlement stage. However, the number of unreported excavation works discovered by the safety management while patrolling the pipeline is over 200 every year, and it is estimated that there are far more unreported excavation works that are not detected. Among the 30 gas pipe damage accidents due to excavation work that occurred in the last 5 years, 77% of the accidents occurred while performing the construction without reporting the excavation to the excavation information support center. It is still high. In the end, in order to reduce the occurrence of accidents due to excavation work, measures to prevent accidents due to unreported and unauthorized excavation work that have not been reported are required.

We propose an excavator management method and system that can prevent accidents caused by excavation work, including undeclared unauthorized excavation work, in advance.

Excavator management method according to an embodiment of the present invention is performed by a server, comprising the steps of periodically receiving the location information of at least one excavator; monitoring whether the excavator is located in a restricted area; And when detecting the excavator located in the restricted area comprises the step of notifying it to the manager.

The monitoring may include: identifying the restricted area based on underground facility location data; and determining whether the location information of the excavator is located in the restricted area.

The restricted area is an area within a standard radius from the underground facility.

The step of notifying comprises: checking the elapsed time since the excavator enters the restricted area; and issuing a dispatch command to the excavator position when the elapsed time exceeds a reference time.

The notifying step further includes notifying the excavator that has entered the restricted area.

A transmitter device for an excavator according to an embodiment of the present invention is a device for communicating with an excavator management server, comprising: a GPS module for receiving location information by communicating with a plurality of artificial satellites; a communication module for periodically transmitting the location information to the server; a control unit for controlling the overall operation based on the operation of transmitting the location information to the server and the information received from the server; and a power supply unit for supplying power required to the GPS module, the communication module, and the control unit.

The sending device for the excavator further includes an alarm unit for transmitting a notification from the server to the driver of the excavator.

Excavator management system according to an embodiment of the present invention is provided in the excavator and at least one excavator transmitter for periodically transmitting its location information; a server for determining whether the excavator is in a restricted area based on the location information received from the excavator transmitter and notifying the manager; and a repeater for relaying communication between the excavator transmitter and the server having different communication methods.

The present invention can prevent an underground facility accident caused by an excavator in advance by fundamentally controlling and managing illegal or unreported excavator construction.

In addition, it is possible to accurately determine the working status of all registered excavators within the restricted area, and it is possible to prevent valuable lives and enormous property damage at low cost.

FIG. 2 shows a temporary scenario of the operation of the excavator management system shown in FIG. 1 .

Referring to FIG. 2 , the currently monitored excavator 210 is located near the area where the gas pipe 220 is buried, but is still located outside the restricted area (see FIG. 2A ). In this example, the area within 3 m of the gas pipe was set as a restricted area. Thereafter, when the excavator 210 being monitored enters the restricted area while moving, it notifies the manager and the server 110 specifies the excavator 210 as a significant monitoring target (see FIG. 2b ). In addition, the server 110 may notify the excavator 210 driver of this. The server 110 may inform the driver of the excavator 210 that the excavator has entered the restricted area by using an alarm means such as a buzzer or a warning light. Thereafter, if the excavator 210 is out of the restricted area within the reference time, the server 110 may stop the operation of the alarm means and exclude it from the monitoring target (see FIG. 2C ). In this example, the reference time was set to 1 minute.

Figure 3 shows another scenario of the operation of the excavator management system shown in Figure 1; Unlike the scenario of FIG. 2 , the excavator does not deviate from the restricted area within the reference time.

Referring to FIG. 3 , the currently monitored excavator 310 is located near the area where the gas pipe 320 is buried, but is still located outside the restricted area (see FIG. 3A ). In this example, the area within 3 m of the gas pipe was set as a restricted area. Thereafter, when the excavator 310 being monitored enters the restricted area while moving, it notifies the manager and the server 110 specifies the excavator 310 as a significant monitoring target (see FIG. 3b ). In addition, the server 110 may notify the excavator 310 driver of this. The server 310 may use an alarm means such as a buzzer or a warning light to inform the driver of the excavator 310 that he has entered the restricted area. Thereafter, if the excavator 310 is still in the restricted area until the reference time has elapsed, the manager may be notified of this, and a dispatch command may be issued to the site safety team to the location of the excavator 310 (see FIG. 3c ). ). The on-site safety team 330 quickly moves to the location of the excavator 310 to check whether the excavation work is in progress. In this example, the reference time was set to 1 minute.

As described with reference to FIGS. 1 to 3, the excavator management system according to an embodiment of the present invention automatically compares the position of the excavator with the position of the underground facility to prevent the excavator from approaching the underground facility in advance. In addition, when the excavator enters a preset restricted area, the first alarm is transmitted, and if the excavator stays in the restricted area for a certain period of time despite the first alarm, the management headquarters will dispatch to the site to crack down. In addition, since the real-time location of the excavator is transmitted directly to the management headquarters, it is possible to shorten the on-site dispatch time.
