Fig. 2 shows a functional relationship diagram among the cloud platform server end system, the cloud platform database, and the data acquisition device according to the embodiment of the present invention. Referring to fig. 2, first, a data acquisition device initiates a long connection request with a cloud platform server end system through a Socket communication technology based on a TCP/IP protocol, and sends an encrypted data packet containing device basis information, specifically, an encryption mode of the encrypted data packet is AES encryption, and the device basis information includes a device number.
Secondly, the cloud platform server end system receives an encrypted data packet from the data acquisition equipment through the port of the open Socket server end;
after receiving the encrypted data packet, the cloud platform server end system verifies whether the format of the encrypted data packet is correct, discards the encrypted data packet if the format is wrong, and rejects the long connection request of the data acquisition equipment; if the format is correct, the encrypted data packet is decrypted by adopting a decryption key, if the decryption fails, the encrypted data packet is discarded, the long connection request of the data acquisition equipment is refused, and if the decryption succeeds, the data item obtained by decryption is analyzed to obtain the basic information of the equipment;

And finally, after the data acquisition equipment is remotely controlled and parameter configured by the cloud platform server end system, the data acquisition equipment feeds back a corresponding execution result to the cloud platform server end system, and the cloud platform server end system records the received feedback result in the cloud platform database.
In the embodiment of the invention, the main service logic of heartbeat detection is as follows:
a data acquisition client installed in the data acquisition equipment regularly and actively sends a heartbeat packet to a cloud platform server end system at a frequency set by the cloud platform server end system, the cloud platform server end system updates a heartbeat detection record of the data acquisition equipment after receiving the heartbeat packet, the cloud platform server end system judges whether the data acquisition equipment is normally online through heartbeat detection, and if the data acquisition equipment does not send the heartbeat packet within a certain time (set by the cloud platform server end system), the data acquisition equipment is judged to be offline;
if the data acquisition equipment cannot establish network connection with the cloud platform server end system within a certain time, the data acquisition equipment can be automatically restarted, and the problems caused by network reasons such as DNS abnormity and the like are solved. If the automatic restart exceeds N times (the background is configurable), the system still cannot be normally connected to the cloud platform server end system, the configuration is reset and restarted, and the connection to the cloud platform server end system is tried again after the restart is completed.

active remote control: the user can directly issue remote control commands such as restarting equipment, locking/unlocking equipment, configuring serial ports and the like to the data acquisition equipment which keeps long connection on line through a front-end interaction tool (front-end UI or mobile APP).
Passive remote control: aiming at the data acquisition equipment which can not keep stable online long connection due to network and other reasons, the control of the data acquisition equipment is realized by adopting a mode of asynchronously issuing a remote control command. After a user sets a relevant remote control command and selects data acquisition equipment to be controlled, the cloud platform server-side system records relevant information into the cloud platform database. After the data acquisition equipment initiates heartbeat detection and the cloud platform server end system receives the heartbeat detection, the cloud platform server end system judges whether a remote control command to be issued exists or not by inquiring the database, and if the remote control command exists, the remote control information is subjected to command code assembly and encrypted issuing.
In the embodiment of the present invention, the main service logic of parameter configuration is:
a user firstly sets a default configuration (comprising a data acquisition interval, a heartbeat detection interval, a cloud platform server address, a network-off restart time length and a message encryption key) of all data acquisition equipment through a front-end interaction tool (a front-end UI or a mobile APP), after the data acquisition equipment initiates heartbeat detection and a cloud platform server end system receives, the cloud platform server end system inquires a cloud platform database to confirm whether an exclusive configuration parameter of the data acquisition equipment exists, and if the exclusive configuration parameter does not exist, a same record is copied from the default configuration to be special for the data acquisition equipment; if the configuration information exists, whether the configuration is issued is judged through the special mark of the configuration record, and if the configuration needs to be issued, the parameter configuration information is subjected to command code assembly and encryption for issuing.
Specifically, a fusion flow of heartbeat detection, passive remote control, parameter configuration, and result feedback of the cloud platform server end system according to the embodiment of the present invention is shown in fig. 3, and an implementation flow of active remote control of the cloud platform server end system according to the embodiment of the present invention is shown in fig. 4.
