Novel intelligent heat pipe network leakage and location positioning system and method

Abstract

The embodiment of the invention provides a novel intelligent heat pipe network leakage and location positioning system and method. Specifically, a detection pulse signal with predetermined pulse widthis injected into a signal line, a feedback to-be-detected signal is received within a predetermined time period, and then whether a predetermined fault occurs or not is judged according to whether avoltage value of the to-be-detected signal is less than a predetermined voltage value or not. The transmission speed of the signal is very high, so that the fault can be detected quickly, and the sensitivity of fault detection is improved. Furthermore, the distance between an occurrence site of the predetermined fault and a signal injection end of the signal line can be accurately calculated by using the injection time of the detection pulse signal and the receiving time of the to-be-detected signal after the occurrence of the fault is determined in the technical scheme, thereby being capableof accurately determining the fault occurrence site, and thus being capable of effectively improving the fault removing efficiency. In addition, the setting of a lot of signal acquisition equipment inthe system can be avoided, and the maintenance cost of the system is reduced to a great extent.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication and signal technology, and more specifically, relates to a novel intelligent heat pipe network leakage and location monitoring system and method. Background technique [0002] With the rapid advancement of my country's urbanization process, service systems such as heating systems and water supply systems that are closely related to people's lives are widely used in buildings where people live. These service systems have greatly improved the convenience of people's lives. In order to improve the service quality of the above-mentioned service system, it is necessary to take necessary regulatory measures to ensure that when the service system fails, it can be found and repaired in time. [0003] At present, for systems that provide services through the flow of liquid objects, it is generally judged whether a failure occurs by monitoring the pressure and flow in the system. Howe...

However, this regulatory measure has the defect of low sensitivity, which is specifically reflected in the fact that the pressure data and flow data of the system can be significantly changed after a period of time after the fault occurs, and the fault can only be detected according to the changed pressure data and flow data

During the period from the occurrence of the fault to the detection of the fault, a lot of resources may have been wasted, or a certain amount of damage to the facilities of the service system may have been caused, which not only caused the loss of resources, but also caused damage to equipment.

In addition, the above measures of monitoring service system faults through pressure and flow still have the disadvantage of being unable to accurately locate the fault location, which is specifically reflected in the fact that multiple data acquisition devices are set up in the service system, but the spatial distribution of these data acquisition devices has a large The discreteness of the fault, the service system can only determine the approximate range of the fault based on the data transmitted by the data acquisition equipment, but cannot accurately determine the location of the fault, which seriously reduces the efficiency of troubleshooting, and the arrangement of a large number of data acquisition equipment improves the service. System Maintenance Cost

[0004] In summary, the above-mentioned measures of monitoring service system failures through pressure and flow have the disadvantages of low sensitivity and inability to accurately locate the fault location
