Problems solved by technology

[0003] The traditional safety production comprehensive supervision platform lacks data middleware, each manufacturer develops data interface program by itself, the data format is private, no standard data collection standard has been formulated, the interface protocol is closed, and data communication between different manufacturers cannot be realized
Therefore, the transmission method of the traditional safety production integrated supervision platform is single, and it has the following disadvantages: it cannot provide a variety of optional transmission mechanisms, it cannot be compatible with multiple transmission protocols, it does not support cross-platform and distributed deployment, and it is universal and portable. , Poor scalability, general efficiency, not stable enough; there is no feedback mechanism for sending and receiving messages; partly through the transmission mechanism of message middleware to realize the interaction of message data between systems, but message middleware is not suitable for realizing the system transfer of large amounts of data between

Embodiment 1

[0073] The client data type is database:

[0074] 1.1 The client needs to configure content: client name, transmission method, database address, user name and password, transmitted entity name (table or view), target server address, port; the configuration information corresponding to the entity name includes the transmission interval, each time The amount of data transmitted, the transmission flag field, the transmission starting point value, the transmission condition, the transmission field name, etc.

[0075] 1.2 The client first reads the information in the configuration file sys.properties, and obtains the client name, data type, database address, table name to be transmitted data, server address and port number and other information.

[0076] 1.3 Obtain the configuration information of the corresponding table according to the configured transmission table name (format: table name.xml), including the time of polling the table In seconds; the number of data rows sent each time ...

Embodiment 2

[0125] Client data type is text file

[0126] 2.1 The client reads the corresponding text file according to the configuration information, adds the data header and transmits it to the server. After the client receives the message that the writing is successful, the local text file is deleted.

[0127] When reading client data, in the configuration of each data file, If there is a data header, the data header is the client name clientname plus the corresponding configuration file name Replace, if not, insert the client name and configuration name into the first line. After receiving the data, the server calls the stored procedure in the corresponding configuration file for processing according to the first row of data.

[0128] 2.2 First obtain the configuration information of the client according to the system configuration file sys.properties

[0129] #Client name

[0130] clientname=23

[0131] #Transmission type 1 indicates that the client data source is a text file 2 indicates tha...

Abstract

The invention discloses a safety production comprehensive supervisory platform data transmission method which is used for achieving data transmission between a client side and a central server, namely a server side. The method comprises the following steps that the client side reads a configuration file, safety production comprehensive data are analyzed, after a client side position flag field value is obtained or updated according to a position flag field value fed back by the server side, the analyzed data generate text message data and the text message data are encrypted, and then the text message data are sent to the server side through Socket communication; after the server side receives the data, the data content is analyzed to be in a target data format to be judged whether it meets writing in conditions, the position flag field value which is not written in is returned to the client side, or after the data are written in, the position flag field value which is successfully processed is returned to the client side, and meanwhile the position flag field value is stored and the server side position flag field value is updated. The method supports calling of various mainstream databases, various text protocols and data interfaces which are popular currently, and can cross platforms and carry out distributed deployment.

Description

Technical field [0001] The invention relates to a data transmission method of a safety production comprehensive supervision platform, in particular to a data transmission method of a safety production comprehensive supervision platform compatible with multiple transmission protocols. Background technique [0002] The comprehensive supervision platform for production safety is a software product used for data extraction at the bottom of the comprehensive supervision process of production safety, which is convenient for data extraction from coal mines, non-coal mines, hazardous chemical enterprises and other systems. [0003] The traditional safety production comprehensive supervision platform lacks data middleware. Each manufacturer develops its own data interface program, the data format is private, there is no standard data collection standard, the interface protocol is closed, and data communication between different manufacturers cannot be realized. Therefore, the traditional sa...
