In existing access control systems, infrared detection, ultrasonic detection or camera detection are usually used to manage access to libraries, archives, warehouses, stores, etc., and to identify the tags of items held by batches of users and to prevent theft of items. However, the detection methods of these access control systems have limitations.

For example, in a system that uses camera technology to identify and manage access control, the human presence detection algorithm is complex and difficult to implement. If there is insufficient light, the camera will find it difficult to detect and track the human body, and the anti-interference ability is weak. At the same time, camera detection also has the risk of privacy leakage. For another example, in a system that uses infrared and ultrasonic technology to identify and manage access control, it is difficult to distinguish between objects and humans, and often fails to read item tags due to recognition errors. In addition, infrared and ultrasonic equipment are large and inconvenient to install.

Embodiment 1

On the one hand, this embodiment provides an ultra-high frequency intelligent security access control device, including: a receiving antenna, a transmitting antenna and a radar module, the radar module includes a crystal oscillator, a memory and a radar chip; the radar module is respectively connected to the receiving antenna and the transmitting antenna or the radar chip integrates the receiving antenna and the transmitting antenna; the radar chip is respectively connected to the crystal oscillator and the memory; the radar module is used to non-contactly detect the presence status and the direction of entering and leaving the door when a moving body passes through the access control through ultra-high frequency radar signals.

It should be noted that, as shown in FIG1 , the ultra-high frequency intelligent security access control device adopts the technology of millimeter wave radar, and realizes the wireless perception of the status of people in a specific place through the human motion perception and human motion direction perception realized by radar technology. The moving body refers to a moving human body or object. In the embodiment, human motion is given priority to explain, and the motion and direction of the human body entering and leaving the door are perceived by radar technology. The ultra-high frequency intelligent security access control device is mainly composed of a receiving antenna, a transmitting antenna and a radar module, and the radar module includes a crystal oscillator, a memory and a radar chip. The radar chip uses a 24GHZ/60GHZ/77GHZ millimeter wave radar chip, such as S32R41, ADT6101-60GHZ of Anda Technology or CAL77S322-AC-77GHZ of Calterah, etc. It can also be other types of radar chips from other manufacturers, and no excessive enumeration and limitation and cumulative description are made here.

Regarding the setting of the transmitting antenna and the receiving antenna, on the one hand, in order to better detect the position of the human body through the radar and subsequently detect the direction of the human body entering and leaving the door, the receiving antenna and the transmitting antenna of the ultra-high frequency intelligent security access control device can be multiple or one. In the best case, there are multiple receiving antennas and transmitting antennas, because multiple groups of receiving antennas and transmitting antennas are conducive to receiving more accurate human position information with higher accuracy. The combination of antennas can be one transmitting antenna and two receiving antennas, two transmitting antennas and two receiving antennas, three transmitting antennas and four receiving antennas. Of course, the number of transmitting antennas and receiving antennas can also be the same, but the optimal configuration is that the number of receiving antennas is more than the number of transmitting antennas. On the other hand, the radar module is connected to the receiving antenna and the transmitting antenna respectively, that is, the receiving antenna and the transmitting antenna can be welded on the PCB printed circuit board together with the crystal oscillator, the radar chip, and the memory. The radar chip can also integrate the receiving antenna and the transmitting antenna, that is, the transmitting antenna and the receiving antenna are integrated in the radar chip in advance, rather than welded on the PCB board. The advantage of the antenna setting of the latter method is that, under the configuration that requires multiple groups of receiving antennas and transmitting antennas, the integration is higher, and the product size of the ultra-high frequency intelligent access control device can be minimized, which is more conducive to installation and use.

The product diagram of the radar module is shown in Figure 3, which is used to detect the presence of a moving body through a door control through UHF radar signals. When a moving body such as a human body passes through a door control, the radar module can detect the presence of the human body through UHF radar signals without contact. The specific method is that the UHF radar signal is received and transmitted through multiple combined radar transmitting antennas and receiving antennas. The memory will pre-store a software strategy for the judgment logic of whether the human body exists at the door control. The software strategy for judging whether the human body exists can avoid environmental noise or interference signals and accurately judge the presence of the human body or whether it passes through the door control. The radar chip can accurately sense the movement of the human body when passing through the door control by reading the software strategy for judging the presence of the human body in the memory, and achieve the purpose of anti-interference and high accuracy.

Specifically, the radar module is connected to the receiving antenna and the transmitting antenna respectively, including: the receiving antenna, the transmitting antenna and the radar module are respectively integrated on a printed circuit board.

Specifically, the radar chip integrated with the receiving antenna and the transmitting antenna comprises: a crystal oscillator, a radar chip and a memory are respectively integrated on a printed circuit board, and the receiving antenna and the transmitting antenna are integrated in the radar chip.

It should be noted that for the setting of the transmitting antenna and the receiving antenna, one approach is to solder the receiving antenna and the transmitting antenna together with the crystal oscillator, the radar chip, and the memory on the PCB printed circuit board. Another approach is to integrate the receiving antenna and the transmitting antenna into the radar chip before leaving the factory, that is, to pre-make the transmitting antenna and the receiving antenna inside the radar chip instead of soldering them on the PCB board. The advantage of the latter antenna setting is that, in the configuration that requires multiple sets of receiving antennas and transmitting antennas, the integration is higher, which can minimize the product size of the UHF intelligent access control equipment and is more conducive to installation and use.

Preferably, it also includes a radio frequency identification module, which is connected to the radar module; when the radar module detects that a moving object passes through the access control, the radio frequency identification module is used to read the tag information of the moving object.

Specifically, the radio frequency identification module includes L UHF antennas, where L>1, and the UHF antennas are used to receive tag information of the moving object.

It should be noted that the RFID module can be integrated with the radar module in one product, as shown in Figure 4, which is a product diagram of an access control device with an integrated RFID module. The RFID module can have one or more antennas. As shown in Figure 2, the optimal number of antennas is 4. The optimal number of antennas is the result of multiple laboratory verifications by R&D personnel. The optimal ratio of the number of antennas does not limit the number of antennas.

Specifically, it also includes a DC power supply, which is connected to the radar module and the radio frequency identification module respectively.

It should be noted that, as shown in FIG. 2 , the security access control device also includes a radio frequency identification module, which can be a mainstream RFID device on the market, used to read the information of the electronic tags on the items carried by the user, so as to facilitate the monitoring of the information of the items entering and leaving the warehouse in stores, libraries, warehouses and other places. The radar module and the radio frequency identification module communicate through GPIO (General Purpose Input Output) or/and serial port connection, and the radar module and the radio frequency identification module are connected and powered by a 12V DC power supply. When the radar module uses the ultra-high frequency radar signal, it receives and transmits through multiple combined radar transmitting antennas and receiving antennas. When the radar chip determines that the human body passes through the access control by reading the software strategy for determining the presence of the human body in the memory, it determines the direction of the human body entering or leaving the door, and the security access control device triggers the radio frequency identification module to read and record the electronic tags on the items carried by the human body. In addition, the radio frequency identification module can read the tag information of multiple items at the same time, and accurately determine whether the goods have left the supermarket, whether the goods have been paid, and other information, and then upload the relevant information to the background server.

Specifically, there are N receiving antennas, where N is a positive integer not less than 1; there are M transmitting antennas, where M is a positive integer not less than 1.

It should be noted that, for the setting of the transmitting antenna and the receiving antenna, in order to better detect the position of the human body through radar and subsequently detect the direction of the human body entering and leaving the door, the receiving antenna and the transmitting antenna of the ultra-high frequency intelligent security access control device can be multiple or one. In the best case, there are multiple receiving antennas and transmitting antennas, because multiple groups of receiving antennas and transmitting antennas are conducive to receiving more accurate human position information with higher accuracy. The combination of antennas can be a combination of one transmitting antenna and two receiving antennas (i.e., M=1, N=2), two transmitting antennas and two receiving antennas (i.e., M=2, N=2), three transmitting antennas and four receiving antennas (i.e., M=3, N=4), etc. Of course, the number of transmitting antennas and receiving antennas can also be the same, but the optimal configuration is that the number of receiving antennas is more than the number of transmitting antennas, so that the position of the human body and the direction of the human body entering and leaving the door can be accurately detected by radar.

Specifically, the ultra-high frequency radar signal is a 24 GHZ, 60 GHZ, or 77 GHZ radar signal.

It should be noted that the ultra-high frequency radar signal is transmitted and received by the radar chip through the transmitting antenna and the receiving antenna. The radar chip in this solution uses a 24GHZ/60GHZ/77GHZ millimeter wave radar chip, such as S32R41, ADT6101-60GHZ of Anda Technology or CAL77S322-AC-77GHZ of Calterah. It can also be other radar chip types from other manufacturers. No excessive enumeration or summary will be made here.
