Movable pressure collecting ball based on bluetooth data transmission

Abstract

A movable pressure collecting ball based on bluetooth data transmission comprises a counterweight bin, an NFC label, bluetooth, an explosion-proof battery, a single chip microcomputer, a pressure sensor and an error correcting temperature sensor (selectable). The collecting ball can flow along with media in a pipeline and records the data values of time and pressure at set intervals, after the collecting ball is taken out from the tail end of the pipeline, the bluetooth is used for transmitting data to a computer, and the pressure values of the pipeline at different positions are acquired through calculation of the data such as the length of the pipeline and the time. The movable pressure collecting ball can effectively solve the problem that the whole line pressure data of most of pipe sections of existing pipelines which are deeply buried, erected overhead, arranged in water and the like are difficult to acquire, can achieve whole pipe section pressure variation detection under the premise that production is not influenced, and non-blind area whole line detection to most of the pipe sections of the existing pipelines can be achieved.

Description

technical field [0001] The invention relates to a pressure collection ball, in particular to a mobile pressure collection ball for data transmission based on Bluetooth. Background technique [0002] Pressure is one of the important parameters reflecting the operation status of the pipeline system. In the pipeline, the pressure of the medium in the pipeline transportation is strictly required. Only when the pressure meets the requirements can the production efficiency and safety be guaranteed. Therefore, it is necessary to detect the pressure of the pipeline It is a necessary condition to ensure the safe operation of the pipeline system. [0003] Existing pipeline pressure detection methods are divided into invasive measurement methods and non-invasive measurement methods. The traditional pipeline pressure detection method is mostly an interventional measurement method, that is, a pressure gauge or a pressure sensor is pre-connected to a specific part of the pipeline, and th...

Problems solved by technology

However, these methods are only suitable for occasions where the pressure measuring point is relatively fixed, and it is very difficult to install instruments or sensors on some deep buried or overhead pipelines, and the process of installing instruments or sensors will destroy the overall characteristics of the pipeline system, making the pipeline under pressure The capacity is reduced, which is easy to cause fluid leakage, especially under high pressure, which is easy to cause accidents. At the same time, it is impossible to monitor the pressure in the pipeline in real time and online

[0004] Non-invasive measurement methods are mainly based on the detection of elastic deformation of pipelines and ultrasonic detection methods proposed in recent years. Although these methods avoid damage to the pipeline structure, their detection accuracy is lower than that of traditional invasive detection methods, and they are susceptible to Influence of environmental factors (especially temperature)

[0005] In summary, no matter the invasive measurement method of directly installing instruments or sensors or the non-invasive measurement method based on deformation or using ultrasonic waves, there are certain limitations. Most pipe sections cannot carry out continuous full-line inspection without blind spots
