Embodiment 1

[0032] like Figure 1 to Figure 3 As shown, this embodiment includes the following steps:

[0033] (A) The medium to be detected enters the casing through the interface pipe and connecting pipe of the pressure transmitter, and the pressure sensor in the casing detects the pressure;

[0034] (B) The pressure signal processing module amplifies the pressure detected by the pressure sensor, performs digital-to-analog conversion processing, and transmits the processed signal to the processor;

[0035] (C) the signal processed by the processor is sent through the wifi module and the antenna;

[0036](D) The staff can obtain the detected pressure data by remotely controlling the drone carrying the signal receiving terminal to the wifi signal coverage of the pressure transmitter; in the above steps, the pressure transmitter includes a housing 1, and The mounting base 5 parallel to the horizontal plane, the connecting pipe 3 is installed under the housing 1, the lower end of the conn...

Embodiment 2

[0040] The difference between embodiment 2 and embodiment 1 is that in step (D), the drone cruises through a preset route. In addition, in Embodiment 2, no display is provided on the housing 1. After the installation is completed, use the pressure transmitter with a display to check the data measured by the pressure transmitter in Embodiment 2. After the calibration is completed, the In use, data can be obtained through the mobile phone only within the coverage of wifi, so that the power module does not need to supply power to the LCD screen, which greatly saves power consumption, prolongs the cycle of battery replacement, and reduces the frequency of maintenance. Just change the calibration pressure when necessary.

Abstract

The invention discloses an inspection method of a pressure transmitter. The method comprises the following steps that (A) a medium to be detected enters into a shell via an interface pipe and a connecting pipe of the pressure transmitter and a pressure sensor in the shell detects pressure; (B) a pressure signal processing module carries out amplification and digital-to-analogue conversion processing on the pressure detected by the pressure sensor and transmits a processed signal to a processor; (C) the signal processed by the processor is sent through a wifi module and an antenna; and (D) work personnel remotely controls an unmanned aerial vehicle carrying a signal receiving terminal and makes the unmanned aerial vehicle enter into a wifi signal covering range of the pressure transmitter so that detected pressure data can be acquired. In the invention, through the unmanned aerial vehicle or a mobile phone held by the work personnel and other mobile terminals, data of the pressure transmitter can be acquired, time is saved and unsafe factors during mountain climbing are avoided; and simultaneously, because a transmission distance is short, the data does not need to pass a signal relay so that the data is accurate.

Description

technical field [0001] The invention relates to the field of transmitters, in particular to an inspection method for pressure transmitters. Background technique [0002] As a monitoring instrument, pressure transmitters are widely used in water conservancy and hydropower, oil production, oil transportation, and gas transmission pipelines. Since oil and gas pipelines are used in many different types of environments, pressure transmitters also need to be adapted to different environments. [0003] Due to the dangerous roads of pressure transmitters used in mountainous areas, it is very troublesome and unsafe for workers to find pressure transmitters and read data; if there is a problem of high cost in long-distance remote transmission of wired data, and Long-distance wireless transmission may result in a higher packet loss rate. [0004] Not only that, but in cold regions, due to the low temperature, the power consumption of the pressure transmitter is fast. In the prior art...
