2 is a door model to recognize a hard hat and safety equipment

3 is a flowchart of a process of photographing in the entry and exit process after RFID recognition

Conventionally, anyone who has only one lock, bar code, biometric (fingerprint, etc.), smart card, etc. is allowed to enter the control area, and it was a way of taking and storing only the camera, but the control of places where safety is important is strengthened. As a result, it is necessary to find out where access is necessary to own a hard hat or safety equipment, and to find out who entered and at what time. However, current control is difficult to control necessary. The present invention is required to have both safety equipment and a hard hat that must be carried in a dangerous area at the same time for the purpose of strengthening the safety of people entering the control area is allowed access to the access area, which is again photographed and stored in the camera to be.

It is a system that keeps safety by immediately generating a warning sound when safety equipment or a hard hat escapes a person's body even after entry. To do this, when the electronic tag is attached to the hard hat and safety equipment to access the control area, the wireless signal is transmitted to the main device next to the entrance, and it is recognized again by the DB of the server by the network. It will be very helpful for safety management by permitting access only if you have a hard hat and safety equipment necessary in dangerous areas such as opening and recording doors with a camera to confirm the entrance of two or more people at the same time. The present invention is a patent pursuing safety by allowing only the person who is allowed for safety at the time of entrance into the danger zone and having to have a hard hat and safety equipment to enter and wear on the body even after entry and exit.

The present invention is a way to allow access only if you have a hard hat and two or more of the safety equipment and not a card, such as a card possessed by the accessor. It is a system that detects the signal of the electronic tag when entering and exits by attaching the electronic tag of different value to the necessary safety equipment and checks whether the occupants have all the necessary safety equipment and automatically opens the door. The possession of safety equipment is a non-contact RFID tag, not a contact type, and when it arrives near the entrance area, the frequency generated from the electronic tag is recognized by the RFID reader installed next to the door to check the accessor with satisfactory conditions and automatically open the door. If you need to remove the box and need more management, you can search the application and D / B on the computer or server connected through the network to check and record the registered person, and open the door. In addition, the camera is equipped with a camera to prevent the door from being opened once and multiple people enter and exit automatically. As the person appears on the camera, the camera automatically starts shooting. It immediately informs the central control center that the door is opened. You can find out how many people went in and out. And in areas where safety equipment should not be released from the body due to inconvenience during work in dangerous areas, tag antennas (readers) installed everywhere detect whether the safety helmet and safety equipment are recognized at the same time as soon as the movement of the passenger is detected. . If the safety equipment is not recognized because it is uncomfortable or troublesome, the buzzer will be sounded immediately and the control room will be notified so that the user can take action.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

When an accessor approaches the door, it is generated from the electronic tag attached to the safety helmet 101 and the safety equipment 102 for safety. When the signal is detected by the antenna (reader) 104 attached to the door, the controller immediately controls the signal. Transmitting to 105 to detect the signal coming from two or more devices to recognize the accessor possessing both to identify the registered licensor and shows how the device 106 automatically locked open.

As a method of opening the door, the electronic tag signal attached to the safety equipment (101, 102) possessed by the antenna (tag reader) 104 recognizes that the two signals from the connected control 105 to open the door immediately In order to manage the identity and time of the visitor and the like by D / B, the server 203 connected to the network 204 is identified and recorded, and divided into a system for opening the door. Since it is a dangerous area among these two methods, it is necessary to keep track of the names of the visitors and the time. Therefore, the control 105 does not process the data, but transmits the data to the personal computer 205 or the server computer 203 via the network 204 to the program. It is being established as a system that records and manages relevant information such as name and time of visitor.

The opening and closing of the door lock device 106 is based on an electrical signal, which is connected to the control 105 and can be controlled by a program, and thus has an automatic opening and closing method and does not require a key or the like as in the past. In addition, when the person recognizes the person after opening and closing the door in preparation for the situation that more than two people in the opening and closing once the door is automatically started recording in the camera 201 installed in the door and stored in the VTR recording device 202, the door is locked Stop recording when it is no longer detected.

Because it is a dangerous area, people can be recognized by the electronic tag antennas (readers) 104 located throughout the danger area so that even after entering and leaving the body, the safety helmet 101 and the safety equipment 102 defined by the body cannot be removed. Determine if both hard hat 101 and safety equipment 102 are recognized. The electronic tag used for this is a normal RFID tag, and the effective distance according to the equipment is usually 1 to 6M. It is selected according to the site situation and the structure of the door, and when an accessor comes near the door, the frequency from the tag is RFID antenna (reader) (104). ), And transmit the unique ID value registered for each tag to the connected controller. Simple places that do not require access records are registered in the controller's built-in D / B and immediately open the door if they are correct.If access is required and there are multiple doors, network the controllers in each door to the network. It collects the server computer in the control room and manages the data required for management such as access time, who is allowed by the program of the server computer. According to the method of registering the accessor according to the control room, any computer or controller 105 connected to the network or the RFID reader 104 may log in with an administrator ID and register the tag and safety equipment of the employee.

Here, the safety equipment does not matter who owns it, and the recognition of the person uses a method of recognizing the employee ID or tag attached to the employee's hard hat. Therefore, this patent can apply two or three or more tags, or apply the rules of safety regulations. In order to prevent the safety helmet or safety equipment from falling into the human body in order to protect the safety of the occupants in the hazardous area, a wireless repeater called an access point (AP) for detecting and detecting signals from RFID tags If the two RFID tag signals registered at the entrance and exit are not detected together, one of the two is separated from the human body and an alarm sounds and the central sensing center is immediately notified so that the safety equipment is never dropped from the human body. .

Therefore, it is a system that guarantees the safety of people by preventing the safety equipments from falling off the human body at any time in and out of the danger zone.

This system is installed inside the door to manage the history of dangerous areas by recording the recorded video of the exiting person, who went out from the tag value, and the time that went out. to be.

The present invention is a system that can be accessed only if you have a safe hat and safety equipment when entering and entering the danger zone and never have safety equipment allowed in the danger zone. It is also a system that ensures safety equipment never leaves the body since it is a dangerous area even after entry.

First, promote safety when entering dangerous areas.

Second, even after entering and exiting, it detects the signal from the RFID tag attached to the prescribed equipment so that no matter how uncomfortable, the human body wears a safety hat and safety equipment so that the safety system is maintained.

Third, when a person opens the door for security of more than one, and a person is detected by the camera installed in the inside, automatic recording starts and records until there is no movement of the person. This ensures that you can later compare the recording time with the roster of people and see if only one person has entered.
