Embodiment Construction
[0044] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.
[0045] The present invention provides a device control method and system, through which all controlled devices in a private APN network are allocated their fixed IP addresses through a DTU module inserted with a special SIM card. When there is no data transmission between the control server and the controlled device, there is no need to maintain the connection, only when there is a data connection, the control server can actively connect to the target controlled device to achieve the control device, perform data transmission and complete device control. In this way, the number of controlled devices supported by the control server is increased, which saves the expenses of server equipment for service providers; reduces the flow of heart...

The invention provides a device control method and a device control system. The device control method is applied to a control server and controlled devices. The control server and the multiple controlled devices are in the same primate access point name APN network. The equipment control method comprises the following steps: acquiring an access control request sent by a client according to the public network address of the control server, wherein the access control request carries the identifier of a target controlled device and a control action; acquiring the IP address of the target controlled device according to the connection between the target controlled device and a data transmission unit DTU which is equipped with a special SIM card, converts IP data and serial data and transmits the IP data and the serial data via a wireless network; establishing a communication link with the target controlled device according to the IP address and the port number of the target controlled device; sending a control instruction to the target controlled device through the established communication link, and making the target controlled device execute the control instruction according to the access control request to complete the control action; and disconnecting the communication link.
Description
technical field [0001] The invention relates to the technical field of private APN network, Internet of Things, and remote device data transmission, in particular to a device control method and system. Background technique [0002] With the rapid development of the Internet of Things, more and more people have begun to understand, recognize and use it. How to provide users with better Internet of Things services has become a problem considered by various Internet of Things service companies. [0003] The networking mode and data connection establishment mode of the Internet of Things directly determine the stability of data transmission, traffic costs, user experience and user satisfaction. [0004] The traditional implementation method is to establish a control server, which has a fixed public network IP and port to provide the transmission control protocol TCP or user datagram protocol UDP connection function; the controlled device is connected to the Internet through the...
