The features, objects, and functions of the present invention will be further disclosed below. However, the following are only examples of the present invention. When the scope of the present invention cannot be limited by it, that is, any equivalent changes and modifications made in accordance with the scope of the patent application of the present invention will still be the essence of the present invention. Without departing from the spirit and scope of the present invention, it should be regarded as a further embodiment of the present invention.

Please refer to FIG. 1, which is a functional block diagram of a door lock device according to an embodiment of the present invention. As shown in FIG. 1, the door lock device 1 includes a wireless transmission unit 10, a processing unit 12, and a lock unit 14. The processing unit 12 is electrically connected to the wireless transmission unit 10, and the processing unit 12 can exchange signals with the lock unit 14. In practice, the processing unit 12 is not necessarily electrically connected to the lock unit 14 in a wired manner, and the processing unit 12 may also transmit signals to the lock unit 14 in a wireless transmission manner. In one example, the wireless transmission unit 10, the processing unit 12, and the lock unit 14 can be installed on the door or the door frame at the same time. The wireless transmission unit 10 and the processing unit 12 can also be installed in the same casing, and the locks can be separately installed. The unit 14 is disposed on a door or a door frame, which is not limited in the present invention. The functions of the above-mentioned components are explained separately below.

The wireless transmission unit 10 has a wireless transmission range for transmitting an authentication request signal and receiving an authentication return signal. The authentication return signal includes personnel identity information and image file information. In practice, the wireless transmission unit 10 may be a transceiver module used by short-range transmission technologies such as wifi, Bluetooth, and zigbee, so that the wireless transmission range will be approximately 300 meters, which is not limited in this embodiment. For example, the wireless transmission range can be 30 cm, 50 cm, 1 m, 3 m, 5 m, 10 m, 30 m, 50 m, 100 m, etc. You can adjust the wireless transmission unit 10's The transmission power or the transmission direction of the wireless signal is limited, thereby changing the wireless transmission range of the wireless transmission unit 10.

In addition, in one example, the authentication request signal can be used to trigger the activation of the application program, and the application program returns the personal identity information and image file information to the wireless transmission unit 10 as an authentication return signal. Personal identity information is related to the personal information of the inspected person, for example, it can include name, work number, identification number or other relevant information that can identify who the inspected person is. In addition, the personal identity information can also be related to the extended information of the inspected personnel, for example, it can also include emergency contacts, mobile phone numbers, addresses, professional skills, licenses, blood types, attendance status, or information that can be linked to the inspected personnel. The image file information may include the image file itself or information derived from the image file itself.

As an example of actual operation, the wireless transmission unit 10 may send an authentication request signal to a specific mobile device (not shown), for example, a mobile phone of a person under test, and trigger an application that is pre-installed in the mobile device (not shown) ). For example, the application can read the preset name, work number, identity card number or other information that can identify the person being inspected from the mobile device, or the application can pop up the authentication interface and ask for the name, work number, identity card number, or Other information that can identify the person being inspected. In addition, the app can also turn on the camera of the mobile device and ask the person to be inspected to take a specific object with them. This embodiment does not limit that the application can be an application installed in a mobile device or an application installed in a remote server.

The processing unit 12 determines whether the authentication return signal meets the set conditions, and selectively generates a door lock signal accordingly. In practice, the processing unit 12 can verify whether the inspected person has the right to enter a specific area by using the personal identity information. Even if the inspected person has the authority, it also needs the aforementioned image file information. Meet the set conditions. In one example, the setting conditions may be that the identity information of the person meets the authority and that the image file itself exists, but the processing unit 12 does not recognize the content of the image file itself. In another example, in addition to the image file itself, the processing unit 12 identifies whether the content of the image file itself contains the designated object. When the processing unit 12 determines that the identity information of the person meets the authority and the image file itself contains the designated object, Then the set conditions are met. In a narrow sense, the designated object may refer to an item that the inspected person carries and wears. In a broad sense, the designated object may refer to the image file itself. This embodiment does not limit the form of the designated object.

In yet another example, the application can identify whether the content of the image file itself contains the specified object, and the recognition result is wrapped in the authentication return signal as the image file information. When the processing unit 12 determines that the identity information of the person meets the authority, and the content of the image file information indicates that the image file itself contains the specified object after being identified, it meets the set conditions.

The setting condition is related to the setting position of the door lock device 1. For example, if the door lock device 1 is installed at a construction site or an entrance of a construction site, the designated object may be a helmet, a reflective vest, or a safety rope. If the door lock device 1 is provided at the entrance of the clean room, the designated objects may be clean clothes, shoes, headgear, masks, gloves, and the like. Therefore, the setting conditions may be different according to the requirements and specifications of the area to be regulated. When the set conditions are met, the processing unit 12 generates a door lock signal, and the lock unit 14 is controlled by the door lock signal and is set to a locked state or an unlocked state. The lock unit 14 may be an electronic lock or a mechanical lock. As long as it has the function of access control, this embodiment does not limit the form of the lock unit 14.

This embodiment does not limit the authentication request signal to only one mobile device, nor does it limit the acquisition of personnel identity information and image file information from a single mobile device. For example, the authentication request signal may also be sent to one or more cameras, and the camera that receives the authentication request signal is required to photograph the inspected person, or the designated object that the inspected person carries with him. In other words, personal identity information and image file information can be obtained from different devices. Please refer to FIG. 2, which is a functional block diagram of a door lock device according to another embodiment of the present invention. 2 is the same as FIG. 1, and the door lock device 2 also includes a wireless transmission unit 20, a processing unit 22, and a lock unit 24. The processing unit 22 is electrically connected to the wireless transmission unit 20, and the processing unit 22 can exchange signals with the lock unit 24. The difference between FIG. 2 and FIG. 1 is that the door lock device 2 is more electrically connected to the object detection unit 26, and the authentication return signal mainly includes personnel identification information. The function of identifying the designated object is processed by the object detection unit 26 instead, and the identification The way of specifying objects does not limit the use of image recognition technology. In addition, the door lock device 2 employs an environmental detection unit 28 and is used to detect the state of the surrounding environment and generate an environmental signal accordingly.

In detail, the processing unit 22 determines whether the authentication return signal returned by the wireless transmission unit 20 meets the set conditions, and generates a control signal when the authentication return signal meets the set conditions. In other words, when the processing unit 22 judges that the personal identity information has the access authority, the set conditions are met, and the processing unit 22 can generate a control signal. When the object detection unit 26 receives the control signal from the processing unit 22, it detects whether there is a designated object within its detection range and generates a detection result signal accordingly. In one example, in order to prevent the object detection unit 26 from detecting at any time and causing unnecessary waste of power, it is designed to further activate the object detection unit 26 after the processing unit 22 determines that the personal identity information has access authority.

In one example, the object detection unit 26 may be a camera for capturing images of people. Of course, in order to maintain the photographing resolution, the camera has a framing range, and the framing range is the detection range. When the object detection unit 26 captures an image of a person, it is transmitted to the processing unit 22. When the processing unit 22 recognizes the specified object from the image of the person based on the detection result signal, a door lock signal is generated, so that the lock unit 24 is set to the unlocked state. Conversely, when the processing unit 22 does not recognize the designated object from the person image according to the detection result signal, the door lock signal is not generated, and the lock unit 24 is still set to the locked state.

In another example, the object detection unit 26 is a barcode scanner, and the object is designated as a barcode. The barcode scanner should have a scanning range, which is the detection range. The object detection unit 26 can scan the barcode in the scanning range and send it to the processing unit 22. When the processing unit 22 determines that there is a bar code in the detection range according to the detection result signal, a door lock signal is generated, so that the lock unit 24 is set to the unlocked state. Conversely, when the processing unit 22 determines that there is no barcode in the detection range according to the detection result signal, the door lock signal is not generated, and the lock unit 24 is still set to the locked state. In practice, taking the door lock device 2 at the entrance of a construction site or construction site as an example, a bar code can be pasted or displayed on the appearance or prominent place of a safety helmet, reflective vest or safety rope. The inspected person can check the identity before entering the restricted area. Later, it is necessary to scan the barcode on the above equipment to ensure that the inspected personnel have the correct equipment to carry or wear to reduce work safety issues.

In yet another example, the object detection unit 26 is a wireless tag detector, and the object is designated as a tag. The wireless tag detector should have a wireless detection range, that is, the detection range. The object detection unit 26 may search for a tag in the wireless detection range and send it to the processing unit 22. When the processing unit 22 determines that there is a tag in the detection range according to the detection result signal, a door lock signal is generated, so that the lock unit 24 is set to the unlocked state. Conversely, when the processing unit 22 determines that there is no tag in the detection range according to the detection result signal, the door lock signal is not generated, and the lock unit 24 is still set to the locked state. In practice, taking the door lock device 2 at the entrance of a construction site or construction site as an example, the tag can be embedded and fixed on a hard hat, reflective vest or safety rope. After the identity of the inspected person is checked, the wireless tag detector is It can automatically find the proper labels to ensure that the inspected personnel are carrying or wearing the correct equipment to reduce work safety issues.

The environment detection unit 28 is not limited to being installed in or outside the control area, and it is not limited to whether the processing unit 22 is wired or wirelessly connected. In practice, the position that can be detected by the environment detection unit 28 determines the setting position, or can be set Where special attention is needed. As an example, the door lock device 2 is installed at a construction site or at an entrance of a construction site. The environmental detection unit 28 may be installed on a floor under construction or in a particularly dangerous place, such as the windward side of a high-rise building, or a basement where gas is easily accumulated.

Taking a practical example, when the wind speed is too high, which increases the danger of high-altitude operations, it is generally not easy to find immediately. In this embodiment, the environmental detection unit 28 can be used to detect the wind speed. By setting the environmental detection unit 28 Environmental signals related to wind speed are generated in terrain air vents, suspension bridges, engineering elevators, personnel hanging places or other areas with strong winds. When the environmental signal indicates that the wind speed is too high to be suitable for operation, the processing unit 22 stops allowing personnel to enter the control area, so that the lock unit 24 remains locked. In addition, when constructing in tunnels or underground buildings, the environment detection unit 28 can also be installed in a place where gas is easily accumulated, and the environment detection unit 28 can be used to detect the presence of harmful gases and generate environmental signals related to harmful gases . When the environmental signal indicates that the concentration of harmful gas is too high to be suitable for operation, the processing unit 22 stops letting people enter the controlled area, so that the lock unit 24 remains locked. That is, the processing unit 22 can directly control the lock unit 24 to maintain the locked state regardless of whether the object detection unit 26 checks the equipment or regardless of the result of the equipment inspection because the environmental signal does not meet the set conditions.

In addition, the processing unit 22 may also adjust the equipment standard of the inspected person according to the environmental signal, that is, the standard of the equipment carried or worn by the inspected person may be changed. For example, when the environmental signal indicates that the concentration of harmful gas is high, the processing unit 22 may additionally list gas masks and oxygen cylinders as necessary equipment. If the detection result signal indicates that the person being inspected is wearing or carrying a gas mask or oxygen gas correctly Bottle to allow personnel to enter the control area and set the lock unit 24 to the unlocked state. If the detection result signal indicates that the person being inspected is not wearing or carrying a gas mask or an oxygen cylinder correctly, stop allowing the person to enter the control area and keep the lock unit 24 locked.

Here, although the environment detection unit 28 is not shown in the previous embodiment, for convenience of explanation, the functions of the environment detection unit 28 are also described in this embodiment, but in practice, the environment detection unit 28 can also be used in conjunction with the previous embodiment. operating. For example, when the environmental signal indicates that the concentration of harmful gases is high, the processing unit of the previous embodiment can additionally identify whether the content of the image file itself contains a gas mask or an oxygen cylinder. When the processing unit determines that the identity information of the person meets the authority and the image file After being identified, in addition to the equipment that should be worn or carried, it also includes a gas mask and an oxygen cylinder to meet the set conditions.

In summary, different from the traditional access control equipment that only decides whether to release based on the identity of the inspected person, the present invention provides a door lock device. If it is installed at the entrance of a construction site or construction site, it can allow the inspected person to verify the identity by using a mobile device. You can also let the inspected person check whether they are carrying sufficient safety equipment, or use the object detection unit to check whether the inspected person is carrying sufficient safety equipment. If the safety equipment is not complete, the inspected personnel can be notified to make up or wear, which can better maintain the safety of the inspected personnel or related places.
