In order to facilitate understanding of the embodiments of the present invention, a control method system of an access control system based on the internet of things, which is shown in fig. 1, is first described in detail as an example of a control method system of an access control system based on the internet of things, which is applicable to the embodiments of the present invention. Fig. 3 is a schematic diagram of a control method system of an access control system based on the internet of things, which is applicable to the control method of the access control system based on the internet of things according to the embodiment of the present invention.

As shown in fig. 1, the control method system of the access control system based on the internet of things may include: a plurality of terminal devices.

The terminal device may be a terminal having a wireless transceiving function or a chip system provided in the terminal. The terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (SELF DRIVING), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (SMART GRID), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (SMART CITY), a wireless terminal in smart home (smart home), a vehicle-mounted terminal, an RSU with a terminal function, or the like. The terminal device of the present application may also be an in-vehicle module, an in-vehicle component, an in-vehicle chip, or an in-vehicle unit that is built in a vehicle as one or more components or units, and the vehicle may implement the method provided by the present application through the in-vehicle module, the in-vehicle component, the in-vehicle chip, or the in-vehicle unit. The communication between terminals may be a communication between terminals, which may also be referred to as side-by-side communication.

The terminal device is provided with a plurality of antenna panels (pannel), such as a first antenna panel and a second antenna panel. Each of the plurality of antenna panels may transmit or receive a plurality of beams in a different direction, referred to as the plurality of beams of the antenna panel.

A beam refers to a special transmitting or receiving effect with directivity formed by a transmitter or receiver of a network device or terminal through an antenna array, similar to a beam formed by a flashlight converging light into one direction. The signal is sent and received in a beam mode, so that the transmission data distance of the signal can be effectively improved. The beams used for communication between terminals may also be referred to as sidelobes.

The beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technique may specifically be a digital beamforming technique, an analog beamforming technique, or a hybrid digital/analog beamforming technique, etc.

The beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, the terminal feeds back the measured resource quality, and the network device can know the quality of the corresponding beam. During data transmission, the beam can also be indicated by its corresponding resource. For example, the network device indicates a transmission configuration indication-state (state) through a transmission configuration number (transmission configuration index, TCI) field in downlink control information (downlink control information, DCI), and the terminal determines a beam corresponding to the reference resource according to the reference resource included in the TCI-state.

In a communication protocol, the beams may be characterized specifically as digital beams, analog beams, spatial filters (spatial domain filter), spatial filters (SPATIAL FILTER), spatial parameters (SPATIAL PARAMETER), TCI-states, etc. The beam used to transmit the signal may be referred to as a transmit beam (transmission beam, or Tx beam), spatial transmit filter (spatial domain transmission filter), spatial transmit filter (spatial transmission filter), spatial transmit parameters (spatial domain transmission parameter), spatial transmit parameters (spatial transmission parameter), and the like. The beams used to receive the signals may be referred to as receive beams (or Rx beams), spatial receive filters (spatial domain reception filter), spatial receive filters (spatial reception filter), spatial receive parameters (spatial domain reception parameter), spatial receive parameters (spatial reception parameter), and the like.

It will be appreciated that embodiments of the application are described in terms of beams in general, but that beams may alternatively be understood as other equivalent concepts and are not limited to the concepts mentioned above.

It can be further understood that the embodiment of the application is described by taking the example that the terminal equipment is access control sensing equipment.

Fig. 2 is a schematic flow chart of a method according to an embodiment of the present invention. The control method of the access control system based on the Internet of things is applicable to the system and relates to interaction among a plurality of access control sensing devices. The specific flow is as follows:

S201, the first access control sensing device receives the sending beams from the access control sensing devices through the receiving beams of the first access control sensing device.

The first access control sensing equipment is provided with an antenna panel, so that the antenna panel is used for carrying out beam forming, and transmitting and receiving beams in different directions. Similarly, the multiple access control sensing devices are respectively provided with an antenna panel, so that the antenna panels are used for carrying out beam forming, and corresponding transmitting beams are transmitted to different directions. On this basis, the first access control sensing device may perform a beam management procedure, that is, the first access control sensing device receives, using each receiving beam of the first access control sensing device, a plurality of transmitting beams of the plurality of access control sensing devices, so as to determine a beam quality of the transmitting beam received by each receiving beam, such as a reference signal receiving Power (REFERENCE SIGNAL RECEIVING Power, RSRP). In this way, the first access control sensing device may determine a receiving beam with the best beam quality in the sending beams received by each receiving beam of the first access control sensing device, where the receiving beam with the best quality and the sending beam corresponding to the receiving beam with the best quality are a beam pair, which is called a beam management flow.

S202, the first access control sensing device determines the positions of a plurality of access control sensing devices according to the receiving beam and the sending beam.

According to a possible design scheme, the first access control sensing device determines respective positions of the access control sensing devices according to the beam quality of a transmitting beam of each access control sensing device in the plurality of access control sensing devices and the beam direction of a receiving beam used by the first access control sensing device for receiving the transmitting beam of each access control sensing device, namely, dynamic positioning is realized through the beams, positioning is more flexible, and even if the positions are adjusted, the positioning can be carried out through the beams again to determine the latest position.

The following is a detailed description:

First, the first entrance guard sensing device may determine, according to beam quality of at least two transmission beams of each entrance guard sensing device, an included angle between each transmission beam of the at least two transmission beams and at least two reception beams used by the first entrance guard sensing device to receive the at least two transmission beams, and determine at least two included angles altogether.

For example, the first access control sensing device may determine, according to beam quality of a first transmission beam of the at least two transmission beams, that an included angle between the first transmission beam and a first reception beam of the at least two reception beams used by the first access control sensing device to receive the first transmission beam is ±α° at an intersection position; the better the beam quality of the first transmission beam, for example, the larger RSRP, that is, the smaller the attenuation of the transmit and receive energy of the first transmission beam and the first reception beam, that is, the more the first transmission beam and the first reception beam are directed toward each other, in other words, the larger the included angle. Conversely, the worse the beam quality of the first transmit beam, e.g., the larger RSRP, the greater the transmit/receive energy attenuation of the first transmit beam and the first receive beam, i.e., the greater the angle between the first transmit beam and the first receive beam. Similarly, the first access control sensing device may also determine, according to the beam quality of a second transmit beam of the at least two transmit beams, that an included angle between the second transmit beam and a second receive beam of the at least two receive beams used by the first access control sensing device to receive the second transmit beam is ±β° at an intersecting position.

Then, the first access control sensing device may determine a position of each access control sensing device according to at least two included angles and beam directions of at least two receiving beams.

For example, the first entrance guard sensing device may determine that the included angle is- α ° and the included angle is- β °, that the included angle is- α ° and the included angle is +β °, that the included angle is +α ° and the included angle is- β ° have no intersection point in an extension line direction of the included angle, and that the included angle is +α ° and the included angle is +β ° have a first intersection point in the extension line direction of the included angle, based on the beam directions of the included angles being ±α°, the included angle being ±β°, and the at least two received beams. Thus, the first entrance guard sensing device can determine the position of the first intersection point as the position of each entrance guard sensing device.

The first sending beam is the sending beam with the best beam quality in all sending beams of each entrance guard sensing device received by the first receiving beam; the second transmitting beam is the transmitting beam with the best beam quality in all transmitting beams of each entrance guard sensing device received by the second receiving beam.

It can be appreciated that the positive and negative values of an angle are because the first access control sensing device cannot determine the direction of the transmit beam according to only one included angle. Therefore, positive and negative values of at least two angles are required to determine the position of the access sensing device.

It will be readily appreciated that the following description is provided by way of example.

As shown in fig. 3, the RSRP of the transmission beam #2 is larger than that of the transmission beam #1, and therefore, the angle β between the transmission beam #2 and the reception beam #2 is larger than the angle α between the transmission beam #1 and the reception beam # 1. However, the direction of the transmission beam #1 cannot be performed only based on the angle α, and thus the transmission beam #1 in two directions, that is, the angle α°, is sometimes present. Similarly, the direction of the transmission beam #2 cannot be performed based on the included angle β alone, and thus there are two directions of the transmission beam #2, that is, the included angle β°. It can be seen that there is only one first intersection point of the transmit beams in these 4 directions, e.g. W1, i.e. the entrance guard sensing device is located at position W1.

S203, the first access control sensing device controls access control sensing operation of the access control sensing devices according to the positions of the access control sensing devices.

The first entrance guard sensing device controls the direction of the entrance guard sensing devices to execute entrance guard sensing according to the position relation between the positions of the entrance guard sensing devices and the positions of the areas to be sensed, and the power of the entrance guard sensing devices to execute entrance guard sensing. Optionally, the direction of the entrance guard sensing devices for performing entrance guard sensing points to the area to be sensed, that is, a beam for entrance guard sensing is sent to the area to be sensed, the beam can be reflected by an object in the area to be sensed and is received by the entrance guard sensing device for sending the beam, so that the entrance guard sensing device can trigger the camera to start to shoot and identify the object. The power of the entrance guard sensing devices for performing entrance guard sensing is positively correlated with the distance between the entrance guard sensing devices and the area to be sensed, that is, the farther the distance is, the larger the power of the entrance guard sensing device is, or the larger the power of the transmitted beam is, the more the beam can be transferred, so as to ensure the sensing quality of the area to be sensed.

For example, the plurality of entrance guard sensing devices include a second entrance guard sensing device and a third entrance guard sensing device, a distance between the second entrance guard sensing device and the to-be-sensed area is smaller than a distance between the third entrance guard sensing device and the to-be-sensed area, power of the third entrance guard sensing device for performing entrance guard sensing is larger than power of the second entrance guard sensing device for performing entrance guard sensing, and power of the third entrance guard sensing device for performing sensing when a beam propagates to the to-be-sensed area is smaller than power of the second entrance guard sensing device for performing sensing when the beam propagates to the to-be-sensed area. Therefore, the beam coverage of the area to be sensed is hierarchical, and the interference between the beams is small while sensing is realized.

For another example, the plurality of access control sensing devices include a second access control sensing device and a third access control sensing device, the second access control sensing device is located between the third access control sensing device and the area to be sensed, and a direction in which the second access control sensing device performs access control sensing is different from a direction in which the third access control sensing device performs access control sensing. Therefore, the receiving ratio of the area to be sensed is hierarchical, and the interference between the beams is small while the sensing is realized.
