Description

Technical Field

[0001] The invention relates to the technical field of broadband carrier application in electric information acquisition systems, in particular to an on-site intervention detection system and method based on HPLC network faults. Background Art

[0002] As an important asset for electricity consumption and sales, the metering and collection equipment in the electricity information collection system plays an important role in sensing, measuring, collecting, transmitting, analyzing and judging in the marketing system. With the increase in electricity users and the increase in electricity demand, the degree of mixing of equipment from different manufacturers has increased, and the frequency of data transmission has increased. Combined with the complex and changeable operating environment on site, long-term high-load operation has caused the metering and collection equipment to show various forms of abnormal fault conditions such as periodicity, variability, and difficulty in reproduction.

[0003] The complex and ever-changing power operation environment and the product characteristics of equipment from different manufacturers cause problems such as unclear basis, difficult query, difficult positioning, and long troubleshooting time when the operation and maintenance personnel conduct on-site inspections. At the same time, there is a lack of perfect evaluation methods for equipment in operation or dismantled, and the quality of equipment operation cannot be uniformly monitored. These problems affect the supervision of the operating status of the assets of the procurement system on the one hand, and on the other hand, cause the overall quality and efficiency of the metering and collection equipment to decline. The hidden dangers have not been dealt with for a long time, which also affects the overall benefits of the assets of the procurement system. The existing solution to the above problems is that the on-site operation and maintenance personnel consult the equipment manufacturers to inquire about the causes of the relevant problems or require the equipment manufacturers to cooperate on-site to find and solve the problems. This solution greatly prolongs the time for problem investigation and resolution, while increasing operating costs in all aspects.

[0004] Therefore, it is particularly important to develop an on-site intervention detection system and method for network faults based on HPLC.

[0005] The on-site intervention detection system and method based on HPLC network faults consists of two parts: the on-site fault detection device body (hereinafter referred to as peripherals) and the PDA (Personal Digital Assistant, hereinafter referred to as PDA) master station. Among them, the peripheral serves as an intervention device at the HPLC network fault site. The HPLC network main node is moved to the peripheral body through a standard interface, and then the peripheral body is connected to the power consumption site through a strong power interface, so as to achieve the purpose of intervening in the HPLC carrier network. The PDA master station sends different execution instructions to control the peripheral body to realize the operation status detection of each metering and collection device node in the HPLC network fault site, so as to realize and complete the purpose of HPLC network field node fault detection. The above is the technical background and main content of the detection system and method of the present invention. Summary of the invention

[0006] In order to accurately locate node failures in the HPLC network of the procurement system, the present invention provides a system and method based on on-site intervention detection of HPLC network failures. On the basis of the original failure site, peripherals are used as HPLC network intervention carriers, combined with PDA master station control to simulate on-site HPLC network information flow processing, and through different detection schemes and instruction flow combinations, the full node detection process in the HPLC network is implemented, the response information flow is filtered, intercepted and analyzed, and the purpose of locating and feeding back node failures in the HPLC network is achieved in combination with multi-source data decision-making methods, thereby ensuring the efficiency and accuracy of the detection results and greatly improving the overall value of the assets of the procurement system.
