It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides an industrial vehicle data transmission system. As shown in fig. 1, the system comprises an industrial vehicle intelligent terminal A, an intelligent terminal B and a plurality of servers which are connected through the internet; wherein at least a first server exists among the plurality of servers. The first server creates a first thread and a second thread; the first thread receives industrial vehicle data uploaded by the intelligent terminal A or the intelligent terminal B based on a socket (socket) of a TCP/IP protocol; and after the uploaded industrial vehicle data is analyzed and processed according to a protocol format specified between the intelligent terminal and the intelligent terminal, the data is rendered on a webpage interface of a website of a monitoring platform to which the first server belongs so that a user can browse the data through a browser (such as a user browser 1 in fig. 1). And the second thread adjusts the data format of the industrial vehicle data received by the first thread according to the same protocol format predetermined among the plurality of servers (other servers) and then is used for interaction among the plurality of servers (other servers). And other servers except the first server in the plurality of servers perform data analysis, cleaning and storage on the industrial vehicle data forwarded by the first server based on the same protocol format, and render the industrial vehicle data to a webpage interface corresponding to the website of the monitoring platform to which the industrial vehicle data belongs for browsing of a user. And the first thread and the second thread of the first server share industrial vehicle data in a memory sharing mode.

In one embodiment, the first server may also create a third thread. And the first server analyzes and processes the uploaded industrial vehicle data according to a protocol format specified between the first server and the intelligent terminal by executing the third thread, and renders the data to a webpage interface of a website of a monitoring platform to which the first server belongs for a user to browse. The third thread is specially responsible for analyzing and rendering the received industrial vehicle data in the first server, so that the first thread can be specially used for receiving the industrial vehicle data uploaded by the intelligent terminal and placing the industrial vehicle data into the opened shared memory area, and the first thread does not need to be responsible for analyzing and rendering the received industrial vehicle data. And the first thread, the second thread and the third thread share industrial vehicle data in a memory sharing mode.
The industrial vehicle data transmission system shown in fig. 1 specifically works as follows: when a key switch on the industrial vehicle is closed, power is supplied to an industrial vehicle intelligent terminal, the intelligent terminal creates a socket according to a program code solidified in an internal microprocessor of the intelligent terminal, and a connection request is sent to a first server (a first monitoring management platform server). After receiving a connection request of an intelligent terminal, a first server is normally connected with the intelligent terminal to perform data interaction, and the intelligent terminal uploads collected industrial vehicle data to the first server. The first server is used for receiving uploaded industrial vehicle data by creating a first thread, analyzing the uploaded data according to a protocol format specified between the first server and the intelligent terminal, and rendering the data to a webpage interface corresponding to a website of a monitoring platform to which the first server belongs so that a user can browse the data through a browser (such as a user browser 1 in fig. 1). The analysis processing comprises analysis and cleaning operations of the received industrial vehicle data.
The first server also creates a second thread. And creating a socket in the second thread, binding the socket to a specific port (for example, 8085 port) and starting to monitor and process a connection request from another other server in real time to establish a communication connection. After starting up, the other servers shown in fig. 1 serve as clients, and send connection requests to the first server by opening a specific port (for example, 8085 port) in a TCP/IP protocol to establish communication connections. After establishing normal communication connection with the intelligent terminal, the first server readjusts industrial vehicle data uploaded by the intelligent terminal according to a predetermined unified protocol between the first server and the other servers and forwards the industrial vehicle data to the other servers.
And the other servers are used for rendering the industrial vehicle data forwarded by the first server to a webpage interface corresponding to the monitoring platform to which the other servers belong for the user to browse after analyzing and processing the industrial vehicle data based on the same protocol format. Further, the parsing processing of the industrial vehicle data forwarded by the first server by the other servers includes: resolving, cleaning and storing. When a plurality of other servers (other monitoring platform servers) need to display the data of the industrial vehicle, the second thread performs data interaction with the other servers in a polling mode.
Further, as shown in fig. 2, the present invention also provides an industrial vehicle data transmission method, which includes the following steps:
step 1, a first thread is established on at least one server in a plurality of servers, and the first thread is responsible for receiving industrial vehicle data uploaded by an industrial vehicle intelligent terminal;
step 2, a second thread is established in the at least one server, and the uploaded industrial vehicle data are subjected to data format adjustment based on the same protocol format determined in advance among the plurality of servers and then are used for interaction among the plurality of servers;
and 3, other servers except the first server in the plurality of servers perform data analysis on the industrial vehicle data forwarded by the first server based on the same protocol format, and render the data to a webpage interface corresponding to the website of the monitoring platform to which the server belongs for a user to browse.
Furthermore, the first thread in step 1 of the method is also responsible for rendering the uploaded industrial vehicle data to a web interface of a website of a monitoring platform to which the first server belongs for a user to browse after the uploaded industrial vehicle data is analyzed according to a protocol format specified between the at least one server and the intelligent terminal. And the first thread and the second thread of the first server share industrial vehicle data in a memory sharing mode.
Step 4, a third thread is established on the first server, and the third thread is responsible for rendering the uploaded industrial vehicle data to a webpage interface of a monitoring platform website to which the first server belongs for browsing of a user after the uploaded industrial vehicle data are analyzed according to a protocol format specified between the first server and the intelligent terminal. And the first thread, the second thread and the third thread share industrial vehicle data in a memory sharing mode.
Preferably, the same predetermined set of protocol formats among the plurality of servers of the industrial vehicle data transmission method is specifically a custom JSON format or a previously agreed hexadecimal string format.
