s202, the target camera equipment detects whether the received IP address of the target camera equipment is matched with the IP address of the target camera equipment;
s203, in a case that the IP address of the target camera device matches with the IP address of the target camera device, the target camera device sends a request response message to the request display device based on the IP address of the request display device and the physical address of the request display device, where the request response message at least includes: an IP address of the target image pickup apparatus, a physical address of the target image pickup apparatus;
and S204, the target camera device receives a second request message sent by the request display device based on the physical address of the target camera device, and sends real-time image data shot by the target camera device to the request display device based on the second request message.

A third embodiment of the present invention provides an internet of things system, a schematic structure of which is shown in fig. 5, including:
a plurality of target image pickup apparatuses 1, one or more request display apparatuses 2; wherein the content of the first and second substances,
the request display apparatus is for implementing the image data acquisition method of any one of claims 1 to 4, and the target image pickup apparatus is for implementing the image data transmission method of claim 5.
Fig. 5 is a schematic diagram showing a case of a plurality of request display devices, and does not limit the present invention.
In a specific implementation, the target image capturing device is a camera, and the request display device is a display. Because the display does not have any storage function, in order to enable the display to realize the function corresponding to the display equipment, the invention is that each display is provided with a latch circuit for storing a physical address or a network address.
The latch circuit may include various forms, for example, a form of the latch circuit shown in fig. 6 and 7, and a person skilled in the art may design the latch circuit or use the latch circuit in the prior art according to actual requirements, which is not limited herein. Five Mos tubes are designed in fig. 6 for data latching, one tube is used as a switching tube to access data, and the other four tubes are used as two inverters to input signals and mutually access the output of the other tube. With the gate turned on, after Data comes, the right Q-point Data is output as an inverted output of Data and is input to the left inverter in the form of an input signal, and the output of the left inverter inverts the signal and outputs it to the right again. A data latch is formed of a series of inverters.
After the physical address is stored in the display, the form can be completed in the form of physical burning or data storage for multiple times. The cells storing data are connected in parallel to a decoder formed by comparators. As each switch controlling each register in fig. 7 is turned on (i.e., corresponding to the switch tube of the physical address register circuit in fig. 6), the physical address (ID) recorded in the respective register is read out and output to the output (right side) of the comparator, and the data register and read are completed.
Fig. 8 is a schematic diagram of a topology of a camera connected to a plurality of displays with latch circuits according to an embodiment of the present invention, wherein the topology is a narrow lan, i.e. a single distribution source broadcasts unconditionally to a plurality of displays. The display data passes through the physical transmission layer, and the host is identified through the physical address and the data is spread (the identification process is omitted in the broadcast communication). In the narrow lan, the camera is a one-way broadcast transmission, and any one of the displays receives the signal and displays the same content. The physical address (globally unique ID) is burned into a circuit with a memory function on a display, such as an MIP circuit, and the address can be FF-FF-8F-FF-FF (display), FF-FF-FF-90/FF-FF-FF (camera).
Fig. 9 is a schematic diagram of another topology of the present invention, in which a plurality of cameras are connected to a plurality of displays with latch circuits, the topology being a generalized lan, i.e. multiple distribution sources transmit on demand to multiple displays.
Primary network IP + physical ID: corresponding to the layer two data link layer of the OSI reference model, the switch forwards the data frame according to the "destination MAC address" field in the received data frame, i.e. 32bit (ip) +48bit (id). The method can realize half-duplex broadcast selection of a data link of a display and a camera in a generalized local area network, realize bidirectional selection of the display and the camera, and transmit display contents on a physical link layer after an output end and a data receiving end are determined.
Fig. 10 is a schematic diagram of another topology of the present invention, in which a plurality of cameras are connected to a plurality of displays with latch circuits, and a plurality of displays are grouped, and the topology is ethernet, i.e. multiple distribution sources of different lans transmit to multiple displays on demand. The topology involves one level one IP packet and one level two IP packet. The first-level IP group is responsible for accessing the Internet, and the second-level IP group performs data connection on a display in the group under the condition of the first-level IP group. The router is set as a second-level network IP, and correspondingly, the first request message comprises a first-level network IP + a second-level network IP + a physical ID, namely 32bit (IP) +32bit (IP) +48bit (ID).
When the display needs to find the camera address in the network, it can send a request message that includes the primary IP address and physical address of the sender and the IP address of the receiver. This query packet is broadcast in the network layer because the sender does not know the physical address of the receiver. Each camera in the local area network receives and processes the request message, then carries out verification, checks whether the IP address of the receiver is the address of the receiver or not, and returns a response message only if the camera successfully verified, wherein the response message comprises the IP address and the physical address of the receiver. The message is directly sent to the request party of the request message in a unicast mode by utilizing the physical address of the request party in the received request message.
