Description

Technical Field

[0001] The invention relates to the technical field of bridge structure monitoring, and in particular to a building bridge structure safety monitoring system. Background Art

[0002] As an important part of the transportation network, the safety of bridges is directly related to the safety of people's lives and property and the normal operation of the social economy. By monitoring the health of bridge structures, potential safety hazards can be discovered in time to avoid serious accidents.

[0003] At present, the safety monitoring of building bridge structures is carried out by selecting several monitoring points to monitor several parameters of the building bridge structures, and then transmitting the monitoring data of these parameters to the corresponding decision-making departments. The decision-making departments of the enterprise are responsible for analyzing and evaluating the safety of various parts of the building bridge structures. When the decision-making departments are responsible for the analysis and evaluation of the safety of the building bridge structures, they often use common data sets;

[0004] However, during the data transmission process, network fluctuations may cause data loss and the need for retransmission. The current practice is for the remote monitoring center to be responsible for the data retransmission. This practice does not fully utilize the network transmission potential of different decision-making departments, especially for those common data sets, which may cause the network transmission resources of different decision-making departments to be excessive. In addition, the retransmission of data by the remote monitoring center may delay the analysis and evaluation efficiency of the departmental decision-making department;

[0005] In order to solve the above problems, the present invention proposes a solution. Summary of the invention

[0006] The purpose of the present invention is to provide a building bridge structure safety monitoring system, in order to solve the problem that in the prior art, the data of parameter monitoring data of building bridge structures is lost during transmission, and the remote monitoring center is responsible for the unified data retransmission work. This approach does not fully utilize the network transmission potential of different decision-making departments, especially for those common data sets, which may cause the network transmission resources of different decision-making departments to be excessive, and the remote monitoring center retransmits the data, which may delay the analysis and evaluation efficiency of the departmental decision-making departments;

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A building bridge structure safety monitoring system, comprising:

[0009] The remote sub-center is used to transmit the corresponding supervision data to different supervision departments within the enterprise. The supervision data includes monitoring data of several parameters of the building bridge structure;

[0010] An evaluation and analysis module is used to periodically calculate and obtain the interactive evaluation amount of each regulatory department within a number of evaluation cycles based on the data volume, transmission time and packet loss rate of the supervision data sent down by each regulatory department within these evaluation cycles;

[0011] The department decision-making module is used to monitor in real time the process of all regulatory departments receiving their corresponding regulatory data;

[0012] If a regulatory department is detected at the current moment and P2 data packets need to be retransmitted to it by the remote branch center within P1 time, the department decision module determines the retransmission parameter type for several parameters of the data in the P2 retransmitted data packets based on the number of data packets that need to be retransmitted by all other regulatory departments at the current moment, the data capacity size, and their interaction evaluation amount. The retransmission parameter type includes the transfer path parameter type and the original path parameter.

[0013] Furthermore, the monitoring terminal monitors several parameters of the building bridge structure in real time and collects corresponding monitoring data, and obtains real-time parameter monitoring based on the collected monitoring data of several parameters of the building bridge structure.

[0014] Furthermore, the regulatory data issued by different regulatory departments within the enterprise are transmitted in the form of data packets during the transmission process.

[0015] Beneficial effects of the present invention:

[0016] (1) The present invention monitors several parameters of the building bridge structure by setting up a monitoring terminal. The remote management platform transmits the monitoring data of several parameters of the building bridge structure after format conversion to the corresponding supervision department according to the parameter types required by various supervision departments in the enterprise. The dispatching supervision unit monitors and optimizes the transmission of the dispatched supervision data of each supervision department in real time. In this process, when it is monitored that the number of data packets that need to be retransmitted to a certain supervision department exceeds the preset number within a certain period of time, the dispatching supervision unit selects whether to transmit the retransmitted data packets by the remote monitoring center or by a specific department based on the number of data packets that need to be retransmitted by all other supervision departments at this time, the data capacity size and the interaction evaluation amount thereof. In this way, the network resources of various supervision departments and the remote monitoring center can be allocated more efficiently, thereby improving the reliability and efficiency of the entire bridge structure monitoring network and ensuring that each supervision department can receive the required accurate supervision data in a timely manner, thereby ensuring the safe operation of the bridge;

[0017] (2) The evaluation and analysis module regularly evaluates the ability of different regulatory departments within the enterprise to receive the corresponding issued regulatory data, obtains the corresponding interactive evaluation, and uses it as one of the selected benchmarks for transmitting and retransmitting data packets to ensure the accuracy and real-time nature of the data.

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Figure 1 It is a system block diagram of the present invention. DETAILED DESCRIPTION

[0020] 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.

[0021] like Figure 1 As shown, a building bridge structure safety monitoring system includes a monitoring terminal, a remote management platform, a department decision terminal and an evaluation and analysis module;

[0022] The monitoring terminal is used to monitor several parameters of the building bridge structure.

[0024] A remote distribution platform is used to receive, process and send real-time parameter monitoring data to various departments. The remote distribution platform includes a format conversion unit and a data sending unit;

[0025] After receiving the real-time parameter monitoring data, the remote sub-platform transmits it to the format conversion unit, in which the preset standard formats of all parameters are pre-stored;

[0026] After receiving the parameter monitoring data transmitted in real time, the format conversion unit converts the data format of all parameter monitoring data contained therein into a preset standard format of the corresponding parameter;

[0027] After the conversion is completed, real-time monitoring and processing data is obtained, and the monitoring and processing data includes monitoring data of all parameters after the format conversion is completed;

[0028] The format conversion unit transmits the real-time monitoring processing data to the data sending unit. The data sending unit pre-stores parameter sending data of several regulatory departments. The parameter sending data of a regulatory department includes several parameter names, indicating that the monitoring department needs to receive the monitoring data of these parameters.

[0029] After receiving the real-time monitoring and processing data, the data sending unit extracts the monitoring data with the corresponding parameters converted into the format from the monitoring and processing data according to the parameter names contained in the parameter sending data of each regulatory department, and generates the sending supervision data of the corresponding regulatory department based on the data;

[0030] The data issuing unit transmits the regulatory data issued by all regulatory departments to the department decision-making terminal;

[0031] It should be noted that the regulatory data issued by various regulatory departments are transmitted in the form of data packets during the transmission process;

[0032] A data packet contains part of the monitoring data of the parameter, as well as the location of the monitoring data in the original supervision data issued, and the parameter name to which the monitoring data of the department belongs;

[0033] The department decision module is used by each regulatory department to monitor and manage the safety of bridge structures. The department decision terminal includes a supervisory unit and several department decision units. One department decision unit corresponds to one regulatory department.

In this embodiment, the supervision department includes a structure monitoring department, an environmental monitoring department, an emergency management department, a maintenance management department and a quality supervision department;
