DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-10 , the present invention provides an implementation scheme: Example 1: In order to solve the problem that in the existing industrial automation, the main control of the control system is mainly installed based on the factory workshop. During the application process, the existing control system cannot be portable and moved with manual operation, which limits the application environment. At the same time, it has certain problems in timeliness and operability. Considering the above problems, according to the attached figure of the specification 1, the present application designs a control system for application in industrial automation. In order to improve the convenience of deployment, timeliness and operability of the control system, the present application builds the control system based on the cloud platform and API technology. The industrial main control system is arranged in the control workshop. The main control system is connected through input and output modules and relays. Multiple actuators and sensors. After the main control system collects the data of the actuators and sensors, the cloud platform and the main control system establish an encrypted communication tunnel through the VPN server for secure connection. The data transmission between the cloud platform and the main control system uses the VPN server for real-time transmission, and an identity information verification module is set in the VPN server. The verification method of the identity information verification module of the VPN server is one or more of the following methods: mobile phone verification code login, username and password login, fingerprint authentication and face recognition authentication. The cloud platform is used as a transit. The terminal user needs to check and access the cloud platform and needs to verify the identity information. The terminal is the host computer. The host computer and the cloud platform and the big data analysis platform communicate through AP I establish communication, install APP in the host computer, and access the real-time operation data of the equipment through API, so that technical workers can monitor the equipment operation data at any time and find problems in time. The cloud platform is equipped with firewalls and security gateways to improve data security and avoid network intrusion leading to loss of production data or malicious tampering of data. Technical workers can use the host computer (the host computer is a mobile phone, mobile computer or desktop computer) to complete the calculation, analysis and optimization of the data downloaded from the big data analysis platform, and then use API to transmit the data to the cloud platform. The cloud platform transmits it to the master control through the communication tunnel of the VPN server. The master control transmits the command data to each actuator. The modification command sent by the cloud platform needs to be signed by a message authentication code (MAC). In the actual production process, the security level of the modification command can be set according to the worker's technical relevance.

[0042] The above system uses a VPN server to set up an encrypted communication tunnel between the main control and the cloud platform. The cloud platform and the terminal then establish communication through the API. By utilizing the flexibility of the terminal, the factory main control data can be monitored in real time to improve the monitoring convenience of the control system. The VPN server provides identity information verification and encryption, which can provide a safe and reliable information transmission channel, ensure the security and stability of remote access and data transmission of the factory main control system, ensure the convenience and timeliness of data monitoring, and help improve production safety.

[0043] Embodiment 2: When using the above system, it is necessary to build hardware and software facilities such as cloud platforms and VPN communication tunnels, as well as to develop independent APPs, which is quite difficult for general enterprises. The most important one is the construction of cloud platforms. At present, with the decentralization of cloud technology, some private cloud disks based on cloud platforms have emerged. However, these private cloud disks usually need to be operated based on the servers of network companies, resulting in low security and poor independence for industrial production. Therefore, the present application discloses an industrial cloud controller for control systems used in industrial automation, which builds a small, portable, secure and cloud platform hardware adapted to the above system.

The server main control casing 3 is a motherboard equipped with a cloud platform software, and the server main control casing 3 is connected to the cloud platform storage 1 and the backup storage 4 through a SATA data interface 12. The SATA data interface 12 has the effects of high transmission efficiency and stable transmission. The real-time data transmission between the main control and the cloud platform is completed through the VPN communication tunnel, and the cloud platform communicates with the terminal through the API communication protocol, which is convenient for workers to use the host computer for monitoring and parameter optimization.

[0046] According to the instruction manual Figure 2-4 It can be seen that the power supply of the independent cloud platform casing 2 adopts dual-circuit power supply, and the power supply of the independent cloud platform casing 2 is connected to an overload protection. The overload protection and dual-circuit power supply are used to ensure the stable operation of the cloud platform.

The control panel 31 on the server main control casing 3 is used to control various functional components.

[0048] In the specific implementation process, the cloud platform memory 1, the backup memory 4, and the server main control casing 3 correspond to the first storage installation position 6, the second storage installation position 7 and the server installation position respectively. The cloud platform memory 1 and the backup memory 4 are redundant with each other, which improves the security of data storage. The server main control casing 3 is connected to the cloud platform memory 1 and the backup memory 4 for writing and reading data. A plurality of mechanical hard disks connected in series are respectively installed in the main storage casing 11 and the backup memory 4. The mechanical hard disk has a large data storage capacity and can collect as much production data as possible, which is convenient for subsequent production optimization. The mechanical hard disk is fixed by positioning screws, but the mechanical hard disk uses a magnetic head to control writing, and has high requirements for stability, shock resistance and heat dissipation during long-term operation.

An isolation layer 23 is provided in the independent cloud platform casing 2 to independently wrap the cooling storage seat 54;

[0051] In the specific implementation process, the independent cloud platform casing 2 is divided into an inner liner 21 and an outer shell 22, and the heat exchange cavity 51 is composed of a cavity between the inner liner 21 and the outer shell 22. The coolant is stored in the cooling storage seat 54. The coolant is preferably an oil coolant to prevent the coolant from leaking and damaging the electrical appliances. The coolant in the cooling storage seat 54 is passed into the heat exchange cavity 51 by a circulating pump 55. The coolant exchanges heat with the cloud platform memory 1, the backup memory 4, and the server main control casing 3 in the heat exchange cavity 51. At least one cooling fan is provided on the bottom surface of the cooling storage seat 54. The cooling fan forms a cooling airflow to cool the coolant in the cooling storage seat 54. After cooling, the coolant is added to the heat exchange cavity 51 through the circulating pump 55. The coolant is used to exchange heat with the inner liner 21 to complete the cooling of the cloud platform memory 1, the backup memory 4 and the server main control casing 3.

[0052] According to the instruction manual Figure 4-7 It can be seen that the bottom surface of the above-mentioned independent cloud platform casing 2 is provided with at least two pairs of moving rollers 24, and the moving rollers 24 can push the independent cloud platform casing 2 to move, which is convenient for movement and transfer. The outer shell 22 of the independent cloud platform casing 2 is connected to the side of the inner liner 21 by multiple screws and multiple pairs of sealing strips. The server main control box 3, the cloud platform storage 1 and the backup storage 4 are installed in the inner liner 21. The circulation pipe 53 is arranged outside the outer shell 22 and extends to the bottom of the independent cloud platform casing 2 and is connected to the cooling storage seat 54. One side wall of the inner liner 21 is exposed outside the outer shell 22. The inner liner 21 isolates the heat exchange cavity 51 from the electrical to avoid direct contact between the electrical and the coolant.

[0053] According to the instruction manual Figure 8It can be seen that a push-lock assembly 25 is provided on the top of the shell 22 of the independent cloud platform housing 2 for fixing and installing the independent cloud platform.

The fixing plate 254 is fixed to the wall of the workshop with expansion bolts, and the positioning seat 253 is inserted into the positioning groove 255 to achieve the fixation of the independent cloud platform casing 2 in the horizontal direction of the X-axis and the direction perpendicular to the horizontal. The center of the through hole and the through hole is circular, and a pair of elliptical holes with a short axis end distance less than the diameter of the central circular hole are provided at both ends of the through hole and the through hole. The corresponding rotation limit plate 258 has the same cross-section as the through hole and the through hole, and the diameter of the insertion rod 257 matches the diameter of the central circle of the through hole and the through hole. After 257 passes through all the positioning seats 253, the rotation limit plate 258 is rotated to 90°, so that the rotation limit seat 259 and the rotation limit plate 258 are fixed in position, thereby achieving complete locking of the independent cloud platform casing 2, preventing the positioning seat 253 from disengaging from the positioning groove 255, causing the independent cloud platform casing 2 to tilt and fall when the device is hit, causing data on the mechanical hard disk to be damaged. At the same time, the insertion tube 256 guides the insertion rod 257 on the one hand, and rotates the rotation limit plate 258 in the opposite direction when quickly unlocking, so that the insertion rod 257 is pushed back by the push spring, so that the rotation limit plate 258 quickly disengages from the lock on the independent cloud platform casing 2, and then the cloud platform can be quickly moved, which is convenient for saving equipment data in dangerous situations.

Or the bottom surface of the backup storage 4, a protective gasket 84 is arranged on the upper part of the first storage mounting position 6 and the second storage mounting position 7 corresponding to the buffer gasket 83. The material of the protective gasket 84 is the same as that of the buffer gasket 83. The upper and lower positioning of the protective gasket 84 and the buffer gasket 83 is utilized to realize the positioning and installation of the cloud platform storage 1 or the backup storage 4. By adjusting the reverse pulling effect of the threaded column 82, the adjusting bottom plate 81 pushes the buffer gasket 83 to push the cloud platform storage 1 or the backup storage 4 upward, so that the backup storage 4 and the cloud platform storage 1 contact the protective gasket 84, thereby improving.
