The Wireless connection may be a WiFi (Wireless-Fidelity) connection, a bluetooth connection, a wimax (worldwide Interoperability for Microwave access) connection, a Zigbee connection, a uwb (ultra wideband) connection, or other Wireless connection means now known or developed in the future.
The first platform 102 and the second platform 103 are each provided with their own server, and each server is configured with its own server address and port number.
The first platform 102 may be referred to as an old platform, or may be a platform to which the terminal device 101 is successfully connected and communicates with. The second platform 103 may be referred to as a new platform, compared to the first platform 102, that is, the terminal device needs to connect to communicate with the old platform and also needs to connect to communicate with another new platform. The second platform 103 may be any one of other new platforms except the old platform. Of course, each new platform has its own server address and port number.
Each platform may be configured to perform data interaction with the terminal device 101 and collect terminal device 101 data. And each platform can remotely modify the server address and the port number of the terminal device 101, thereby facilitating the connection and communication between the terminal device 101 and other platforms.
The terminal device 101 is used for controlling or collecting data and performing data interaction with the first platform 102 or the second platform 103. When the terminal device 101 is connected to each platform, it is necessary to configure a service address and a port number of a server corresponding to each platform, and support remote server address and port number configuration.

Referring to fig. 3, fig. 3 is a flowchart of a secure connection method for a device according to an embodiment of the present invention, and as shown in fig. 3, the secure connection method for the device includes the following steps:
Wherein the modification instruction comprises a server address and a port number of the second platform. The server address may be an IP address of the server.
And the server address and the port number of the second platform are used for connection communication between the second platform and the terminal equipment.
And the terminal equipment is used for controlling or acquiring data and carrying out data interaction with the platform. The terminal device and the platform can adopt an internet connection mode, so that information such as a server address, a port number and the like needs to be configured, and remote server address and port number configuration is supported.
When the server address and the port number configured by the terminal device are different, the connected platforms are different. Each platform is correspondingly provided with a server address and a port number which belong to the platform, and the server address and the port number are used for distinguishing servers of other platforms. The servers of each platform may provide the same data services that the data services industry may provide. When the terminal equipment needs to be connected and communicated with other platforms, the terminal equipment can be connected and communicated with the platforms only by configuring the corresponding server addresses and port numbers.
And the platform is used for interacting with the terminal equipment and collecting the data of the terminal equipment, and the platform can remotely modify the server address and the port data of the terminal equipment. Both the first platform and the second platform can implement this function.
Specifically, the modification command may be sent autonomously by the first platform. For example, when the terminal device sends the a data request to the first platform but the first platform does not provide the a data service, the first platform may recommend the second platform capable of providing the a data service to the terminal device. At this time, the first platform sends a modification instruction to the terminal device to provide the terminal device with the server address and the port number of the second platform, so that the terminal device can be connected with the second platform for communication to obtain the data A.
In an embodiment of the present invention, after step 201, the method further comprises the steps of: the server address and port number of the second platform are saved.
Specifically, after the modification instruction is received, the server address and the port number of the second platform provided in the modification instruction may be saved, so as to facilitate connection with the second platform.
It should be noted that, while the server address and the port number of the second platform are saved, the server address and the port number of the first platform may also be saved, so that the terminal device and the first platform can be connected again.
And 202, responding to the first platform according to the modification instruction, and disconnecting the communication connection with the first platform.
Specifically, after receiving the modification instruction sent by the first platform, the terminal device needs to reply that the first platform has received the modification instruction, and can directly disconnect the connection communication between the terminal device and the first platform, so as to connect with the second platform.
The first connection request carries the server address and the port number of the second platform. Of course, the first connection request may also include the type of data requested by the terminal device, the content of the data, and the like.
The first preset condition includes a first preset time range, and is a condition for judging whether the terminal device continues to send a connection request with the second platform. The first preset time range may be set according to actual needs, for example, the first preset time range may be set to 10 seconds, 20 seconds, 30 seconds, 1 minute, or other time ranges. The first preset condition may further include a first preset request frequency, and the first preset request frequency may also be set according to an actual requirement, for example, the first preset request frequency may be set to 5 times, 10 times, 20 times, and the like, and may also be set to a frequency of another value.
The response message is used for replying whether the terminal device receives the first connection request message.
Specifically, step 203 includes the steps of: and after the first connection request is sent to the second platform, calculating real-time first connection time. And judging whether response information of the second platform is received within a first preset time range or not according to the first connection time. And if the response information of the second platform is not received in the first preset time range, judging whether the first connection time exceeds the specified time length. And if the first connection time does not exceed the specified time length, continuously sending the first connection request to the second platform. If the first connection time exceeds the specified duration, step 204 is executed.
More specifically, after sending the first connection request to the second platform, the connection timing is started, and the response information of the second platform is monitored in real time within a first preset time range, so as to determine whether the response information of the second platform is received within the first preset time range. If the response message of the second platform is not received within the first preset time range, time length judgment needs to be carried out once to judge whether the first connection time exceeds the specified time length. If the first connection time is still within the specified time range, the first connection request can be continuously sent to the second platform, and the connection step is executed in a circulating mode. And stopping the connection with the second platform and returning to establish the connection with the first platform until the first connection time exceeds the specified time and no response information of the second platform is received.
It should be noted that the specified duration may be set according to actual needs, and the time range of the specified duration may be the same as the first preset time range, or may be greater than the first preset time range.
Of course, when the first preset condition includes a first preset number of requests, step 203 includes the steps of:
and after sending the first connection request to the second platform, starting to calculate the real-time first connection times. And judging whether response information of the second platform is received within the first preset request times or not according to the first connection times. And if the response information of the second platform is not received within the first preset request frequency, judging whether the first connection frequency exceeds the specified request frequency. And if the first connection times do not exceed the specified request times, continuously sending the first connection request to the second platform. If the first connection times exceed the specified request times, step 204 is executed.
It should be noted that the number of the specified requests may be set according to actual needs, and the number of the specified requests may be the same as the first preset number of requests, or may be greater than the first preset number of requests.
And 204, if the response message of the second platform is not received under the first preset condition, canceling the connection request with the second platform, and sending a second connection request to the first platform under the second preset condition so as to reestablish the connection with the first platform.
And the second connection request carries the server address and the port number of the first platform. And the server address and the port number of the first platform are used for connection communication between the first platform and the terminal equipment.
Specifically, when the second preset condition includes a second preset time range, step 204 includes: and after sending the second connection request to the first platform, starting to calculate the real-time second connection time. And judging whether the response information of the first platform is received within a second preset time range or not according to the second connection time, and if the response information of the first platform is not received within the second preset time range, continuously sending a second connection request to the first platform until the reconnection with the first platform is successful.
More specifically, after sending the second connection request to the first platform, the connection timing is started, and the response information of the first platform is monitored in real time within a second preset time range, so as to determine whether the response information of the first platform is received within the second preset time range. And if the response information of the first platform is not received within the second preset time range, continuing to circularly execute the connection step until the reconnection with the first platform is successful.
Of course, the duration determination may also be performed once to determine whether the second connection time exceeds the preset duration. If the second connection time is still within the preset time range, the second connection request can be continuously sent to the first platform, and the connection step is executed in a circulating mode. And stopping the connection of the first platform and returning to the connection with the second platform again until the first connection time exceeds the specified time and the response information of the first platform is not received. Therefore, the terminal equipment can be connected with the first platform and the second platform, and the terminal equipment can be connected with and communicate with at least one of the first platform and the second platform.
After the terminal device reestablishes the connection communication with the first platform, the server address and the port number of the second platform may be confirmed with the first platform again, and then the connection step with the second platform may be executed again. Or, a server address and a port number of another second platform need to be requested from the first platform, and a connection step needs to be performed with another new platform, so as to meet the access requirement of the terminal device.
It should be noted that, when the terminal device does not receive the response message of the second platform, it may be that a server address or a port number of the second platform is configured incorrectly, and therefore, after reconnecting with the first platform, the server address and the port number of the second platform may be confirmed again, so as to reconnect with the second platform. Or the first platform modifies the server address and the port number of the other platform so as to meet the request requirement of the terminal equipment.
More specifically, when the second preset condition includes a second preset number of requests, step 204 includes: and after sending the second connection request to the first platform, starting to calculate the real-time second connection times. And judging whether the response information of the first platform is received within the second preset request times or not according to the second connection times, if the response information of the first platform is not received within the second preset request times, continuously sending a second connection request to the first platform until the reconnection with the first platform is successful.
In the embodiment of the invention, a modification instruction sent by a first platform is received, wherein the modification instruction comprises a server address and a port number of a second platform; responding to the first platform according to the modification instruction, and disconnecting the communication connection with the first platform; sending a first connection request to the second platform according to the server address and the port number of the second platform, and judging whether response information of the second platform is received under a first preset condition, wherein the first connection request carries the server address and the port number of the second platform; and if the response information of the second platform is not received under the first preset condition, canceling the connection request with the second platform, and sending a second connection request to the first platform to reestablish connection with the first platform, wherein the second connection request carries the server address and the port number of the first platform. Therefore, when the server address and the port number configuration of the second platform (new platform) are wrong, the terminal equipment can be automatically connected to the first platform (original platform) and receive the new server address and the port number configuration. And then, the terminal equipment can be ensured to be connected and communicated with one of the first platform or the second platform, and the access requirement of the terminal equipment is met. And then improve the stability that equipment is connected, still provide the security that equipment is connected simultaneously.
