Step 6: and the cloud server performs modeling processing on the received data to form an operation index.

As shown in fig. 2, the intelligent gateway control method of the present invention specifically includes:

inputting a website http:// XXX. dowaysoft. com/XXX of a background management system in a browser, logging in the background management system after a login page appears, inputting a user name and a password, starting an intelligent gateway setting function, inputting intelligent gateway information comprising an intelligent gateway number, a name, an IP address, a P L C device number corresponding to the device to be controlled, a device name, a device type (for example: Siemens, Schneider, AB and the like), a device number, a communication protocol (TCP/IP or RS485), variables and address mapping corresponding to a P L C device register, starting a condition alarm setting function, and selecting a control variable corresponding to the P L C device to set an alarm condition.

the gateway program of the intelligent gateway is deployed under a disc directory of linux iot equipment, the gateway program is run to a specified directory through a command, and the command is dotnet PltcDateway, api, dll-urls http:// localhost:80, the linux iot equipment starts the gateway program, wherein a port is 80, the linux iot equipment needs to be connected into a local area network through TCP/IP, and the PLC equipment also needs to be connected into the local area network through TCP/IP.

The following connection is exemplified using the schneider modbus communication protocol.

the P L C devices to communicate need to connect to the lan and specify a fixed IP address for each P L C device.

for example, the background management system is provided with two pieces of P L C equipment, wherein one register address in the P L C equipment 1 is 40001 (digital type), two register addresses in the P L C equipment 2 are 40002 (digital type) and 40004 (digital type), respectively, the gateway program stores data into a program memory variable, and simultaneously a TCP/IP port 502 of 192.168.1.10 and 192.168.1.20 is opened by Socket to establish connection.

when the communication protocol is in an RS485 mode, the P L C device does not need an IP address, the P L C device is connected with the linux iot device through an RS485 bus, and the gateway program directly opens a COM1 serial port through a SerialPort to be connected.

after establishing connection with the P-L C device, starting a thread to poll and send byte data (including register address 40001, check code and the like) to a connected port every second, and waiting for receiving a value returned by the register address after successful sending.

And after the returned value is read, comparing the read value with the Data value in the gateway program, if the returned value is changed, recording new Data into a Data directory, naming the new Data into a local file from Data year to month to day, replacing old Data in the memory, and if the old Data is not changed, not recording related Data.

The gateway program starts another thread to read the historical Data under the Data directory every other second, calls the Data in the background management system to be stored in the cloud server, successfully uploads the Data, records the last uploading time and the last Data uploading position, and records the last Data uploading position in the Upload file under the directory, and if the historical Data files before the current day existing under the Data directory are uploaded to the cloud server, the historical Data files before the current day are deleted to relieve the pressure of a Data storage space.

the method comprises the steps that a user opens a peer-to-peer (P-L-C) device monitoring page of a background management system, the monitoring page is displayed in an SVG picture mode, a SignalR client is started after the page is opened, a cloud server is monitored, once data of the cloud server are changed, the data are sent to the SignalR client through the SignalR server, and the client receives the data and then changes the element value state corresponding to the SVG.

The user opens the intelligent gateway monitoring page, the monitoring page calls background management system data every two seconds, the background management system calls an 80-port of an IP address of an intelligent gateway program, CPU, memory, temperature and disk state information of the intelligent gateway is obtained, and the information is displayed in the equipment monitoring page in an icon display mode.

in conclusion, the method can acquire the data of the PLC equipment of each mainstream manufacturer, store the data in the cloud server to form big data so as to form various data model indexes, can alarm abnormal equipment information, reflect the abnormal equipment information on a monitoring graph page in real time, store and analyze historical data, and analyze and prejudge the running track of the equipment through big data analysis along with the accumulation of the data.
