Fig. 2 shows a flowchart of an implementation of the data interaction method provided by the embodiment of the present invention, which is detailed as follows:
in S201, the mobile terminal accesses a local area network where the intelligent terminal device is located.
In this embodiment, when the intelligent terminal device is installed and debugged or actually operated, the intelligent terminal device is often successfully accessed to the local area network of the location through network wiring in an actual application scene. For example, when the attendance machine is installed on a wall at the door of a company, a network connection for connecting an internal network of the company is preset at a position behind the attendance machine, and the connection is connected to the door of the attendance machine, which is then successfully connected to the local area network of the company.
After the local area network where the intelligent terminal device is located is expanded through the wireless AP inside the company, the wireless coverage range of the local area network can be expanded, and the fact that the mobile terminal can be accessed into the local area network where the intelligent terminal device is located and wirelessly connected with the intelligent terminal device is guaranteed only by being connected to the wireless access point inside the company.
In S202, the mobile terminal obtains an IP address and a port number of the intelligent terminal device.
As an embodiment of the present invention, the acquiring, by the mobile terminal, the IP address and the port number of the intelligent terminal device includes:
the intelligent terminal equipment displays a two-dimensional code based on the IP address and the port number information;
and the mobile terminal scans the two-dimensional code to acquire the IP address and the port number of the intelligent terminal equipment.
The two-dimensional code is a planar pattern for recording data symbol information by using a certain specific geometric figure or black and white figures distributed in a two-dimensional direction according to a certain rule. The two-dimensional code is formed by a plurality of geometric shapes corresponding to binary information of the IP address and port number data of the intelligent terminal device, and is displayed on a screen of the intelligent terminal device, pasted on a shell of the intelligent terminal device or displayed in other external information carriers. When the IP address changes, the two-dimension code displayed on the screen can be updated in real time, and other external display modes update the two-dimension code through manual modification. The two-dimensional code is scanned by using the mobile terminal with the photoelectric scanning function, information in the two-dimensional code can be automatically identified and read, processing can be automatically executed, and the real IP address and the port number of the intelligent terminal device can be obtained.
Fig. 3 is a schematic diagram of acquiring an IP address and a port number of the intelligent terminal device in a two-dimensional code manner. As shown in fig. 3, the attendance machine No. 1, whose left side is an intelligent terminal device, displays a two-dimensional code having information of an IP address and a port number of the device on a screen, and the mobile terminal on the right side starts a scanning function, aligns a scanning frame with the two-dimensional code on the attendance machine screen, identifies the two-dimensional code, and finally obtains a real IP address and a port number of the attendance machine No. 1.
As another embodiment of the present invention, the IP address and port number may also be specified by the user directly entering information on the mobile terminal. As shown in fig. 4, specifically, the mobile terminal obtains the IP address and the port number about the intelligent terminal device, which are input by the user, through an input box and a prompt displayed on the screen.

In S203, the mobile terminal sends a connection request to the intelligent terminal device according to the IP address and the port number of the intelligent terminal device.
The IP address allocates a unique logical address to each intelligent terminal device in the local area network, and the mobile terminal searches the intelligent terminal device corresponding to the IP address from the local area network by using the IP address and sends a connection request to the intelligent terminal device.
Since an intelligent terminal device having an IP address can provide many different types of data services, these data services can be implemented by one IP address. In order to determine the specific services required by the mobile terminal, this problem is solved by means of one port number per service.
Preferably, the intelligent terminal device only opens one port to provide data service when in operation.
In the embodiment, according to the IP addresses and the port numbers obtained from multiple ways, the mobile terminal can break the limitation of the geographic spatial position, and interacts with the remote intelligent terminal equipment through a wireless network, so that the stability and the flexibility of data interaction are improved.

After receiving the request data packet based on the private UDK communication protocol, one end of the intelligent terminal equipment performs the following processing: and processing the value of the specified field in the data packet by using a preset algorithm to obtain a second check value related to the data packet.
And the intelligent terminal equipment compares whether the second check value is the same as the first check value in the data packet, and if the second check value is the same as the first check value in the data packet, the intelligent terminal equipment determines that the request data packet is not subjected to illegal tampering by a third party and is a complete data packet. At the moment, the intelligent terminal equipment creates a session window, takes the session information as connection confirmation information and transmits the connection confirmation information to the mobile terminal through a private UDK communication protocol.
According to the embodiment, data can be received and transmitted between the mobile terminal and the intelligent terminal device through the private communication protocol, and the mobile terminal using other communication protocols can not be connected with the intelligent terminal device, so that lawless persons can be prevented from using mobile terminal application programs matched with the intelligent terminal devices of the manufacturers to perform data interaction and management on the intelligent terminal devices of other manufacturers. In addition, the embodiment of the invention further ensures the safe transmission of the data by carrying out integrity check on the received data packet.
