Description

BLE-based Safety Management Monitoring System (BLE)

The present invention relates to a BLE-based facility safety management monitoring system, and more particularly, to a BLE-based facility safety management monitoring system capable of monitoring safety management of various facilities through a BLE-based sensor and a portable terminal or a management server .

In general, construction structures are subjected to loads generated over time, such as aging, wind, earthquake, and vehicle, which are generated irregularly over time, and the behavior of structures also changes with time and acting loads.

However, if the state of the structure is kept constant, the natural frequency, damping coefficient, mode shape, etc. of the target structure, which is expressed as the dynamic behavior characteristic of the structure, are kept constant and this structure is called the integral structure.

However, aging and other damages cause changes in factors such as mass and stiffness, which reflect the characteristics of the structure, and these changes cause changes in the dynamic characteristics of the prototype structure.

Therefore, if a system capable of monitoring the dynamic characteristics of the structure at all times is constructed, the state of the structure can be evaluated in real time and safety can be ensured.

In addition to the above-mentioned construction structures, it will be more important to secure the safety by monitoring in real time the state of the structure and the operation abnormality in the case of the structures such as the cable car operation facilities and the large multi-monitor in the stadium.

In addition, there will be a necessity to secure security security by real-time monitoring of opening / closing of a door in a facility or opening / closing of a window.

Various types of safety management monitoring systems have been proposed according to security needs such as security threats due to the backwardness of a large structure or detection of an error signal that may affect smooth operation of the large structure or unauthorized external intrusion into a structure.

In these cases, a separate monitoring system is required because there is a limitation in checking or checking directly by the administrator or the operator. However, in order to have a comprehensive monitoring system applicable to various situations, a lot of installation and management costs are required, There have been many difficulties in

Therefore, it is urgently required to propose a safety management monitoring system in which safety management of various structures, real-time motion detection or security management can be managed with small cost.

Referring to FIG. 1, a safety management monitoring system 100 according to an exemplary embodiment of the present invention includes at least one BLE sensor 10 for monitoring at least one facility to be managed, And a portable terminal 20 for receiving and collecting data measured by the BLE sensor 10 and analyzing the collected data to confirm an abnormality or a current state of the facility to be managed in real time.

The safety management monitoring system 100 according to the present embodiment includes only the BLE sensors 10 and the portable terminal 20. In this case, the safety management monitoring system 100 according to the present embodiment is not limited to the mountainous area where the communication network is difficult to construct, The BLE sensor 10 and the portable terminal 20 directly communicate with each other without sensing the current state of the facility directly by the operator or the manager so that the sensing data of the BLE sensor 10 is transmitted to the portable terminal 20 ).

In other words, in the case of a cable car driving system in a mountainous region, since the existing communication network is difficult to construct, the BLE sensor 10 according to the present embodiment is installed in the cable car driving system 10 for monitoring a stable cable car driving system such as power transmission of a cable car, So that monitoring can be easily performed.

On the other hand, the BLE sensor 10 is attached to a facility to be managed, and the presence or absence of a door or a window included in the facility, presence or absence of a specific actuator included in the facility, presence or absence of a user in the facility, , Whether or not parts are loosened such as bolts installed at specific locations of the facilities, and distance measurements of cracks or cracks in facilities, and calculates sensing data for each BLE sensor 10.

Accordingly, the sensing data calculated by the BLE sensor 10 is transmitted to the portable terminal 20 and used for overall monitoring including safety management, security management, and operation management of the facility.

The BLE sensor 10 includes an on-off sensor 11 for determining ON / OFF data including presence / absence of a facility to be managed, presence / absence of operation or presence / absence of user access, a distance between a crack or a crack, And a distance sensor 12 for measuring the distance between facilities or the distance between the facility and the user and calculating the distance information.

Here, the on-off sensor 11 is a sensor that calculates sensing data with two result values of YES or NO, and the distance sensor 12 calculates and calculates the information value of the separation distance.

The on-off sensor 11 includes a pin type sensor 11a for detecting the release of a large bolt fastening installed in a facility, a magnetic type sensor 11a for detecting access to the access restricted area and the controlled area of the facility, A sticky type sensor 11c for detecting the loosening of a large bolt fastening installed in a facility or a sticky type sensor 11c attached to the facility with a security seal label for dangerous materials and explosives and detecting the detachment or damage thereof.

In addition, the on-off sensor 11, such as an infrared sensor including a transmitter for irradiating infrared rays and a receiver for receiving the infrared rays, may be configured to perform various functions in various forms.

In addition, the distance sensor 12 includes a crack sensor 12a for measuring a distance between cracks or cracks in a facility, and a sensor for measuring a distance between one or more moving facilities or a facility and a moving user And a spacing position sensor 12b.

The crack sensor 12a includes a slider body 12aa disposed at one side where cracks or cracks are generated, a PIO port 12ab spaced apart from the slider body 12aa, A spring member 12ac which is fastened to one end of the spring member 12ab and a spring member 12ac which is disposed on the other end where the spring member 12ac is in contact with or not in contact with the movement of the spring member 12ac, And a power supply terminal 12ad.
