Embodiment 2

[0061] Such as figure 1 Shown: On the basis of Embodiment 1, a 4G communication system for a crawler crane safety monitoring system includes a crawler crane safety monitoring system, a 4G module, a remote server and a remote data control terminal; the 4G module includes a control unit, Uart port, internal data buffer, parameter setting buffer and data receiving and sending unit; the control unit is connected to the Uart port, internal data buffer, parameter setting buffer and data receiving and sending unit; the Uart port is connected to the internal data buffer And parameter setting buffer and crawler crane safety monitoring system, the data receiving and sending unit is also connected to the remote server. When the remote data control terminal updates the internal parameters of the module to set the buffer data, the remote data control terminal passes the data to be delivered (such as server address pointing, dynamic analysis of key strings, data verification mode items, etc...

Embodiment 3

[0063] On the basis of Embodiment 2, update program function: the remote data control terminal will send module program update instructions to the corresponding data sending and receiving units A, B, and C of the modules at the same time through the remote servers A, B, and C. After the comparison and analysis of the above instructions, the module will return the ready completion flag to the remote servers A, B, and C, and the three groups of remote servers will issue the same update program at the same time, and the module will only compare the three-way data for consistency After passing, directly IAR the program into the Flash of the control chip, and after receiving the sending completion flag in the data, power on and reset the module within the next internal idle node time.

[0064] The remote data updates the safety monitoring system program of the on-site equipment, and the remote data control will issue the monitoring system program update command and send it to the co...

Abstract

The invention discloses a 4G communication system for a crawler crane safety monitoring system, including a crawler crane safety monitoring system, a 4G module, a remote server and a remote data control terminal; the 4G module includes a control unit, a Uart port, an internal data buffer, parameter setting buffer and data receiving and sending unit; the control unit is connected to the Uart port, internal data buffer, parameter setting buffer and data receiving and sending unit; the Uart port is connected to the internal data buffer and parameter setting buffer and crawler type crane safety monitoring system, the data receiving and sending unit is also connected to the remote server. The integrity of the real-time data and control data of the field equipment is verified by the three-way data server at the same time. The uploading and sending of communication data follow this feature, which improves the data security and data integrity of the field equipment in use. It provides a real and reliable data source for subsequent big data analysis of field equipment.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a 4G communication module and method for a crawler crane safety monitoring system. Background technique [0002] At present, the 4G RTU data communication module is used in the safety monitoring system of crawler cranes. Generally, data transparent transmission or Modbus protocol is used. The data to be transmitted in the system is transmitted to the designated server server for processing through the 4G RTU module through sokect. Its characteristics are Point-to-point transmission mode, single data link layer form, vulnerable to loss of real-time data of the equipment monitoring system due to various network equipment failures, and in severe cases, hacker attacks caused by the server will cause the control data of the field equipment in the remote server database to be lost Or be tampered with, which may lead to misoperation and miscontrol of field equipment, which seriously thre...
