Benefits of technology

The present invention provides a data management method for a portable laser gas detector. Unlike conventional methods, this method uses the data management terminal to manage the gas concentration data detected by the laser detector and upload it to the server through a log or report. This solution solves the problem of data management for portable gas detectors. Additionally, the invention provides an inspection crew with a convenient and easy-to-use data management terminal that can automatically trigger a pre-shooting mode when a leak point is detected, reminding the leak inspection crew while displaying the target gas concentration data. This leads to faster and more efficient leak detection operations and improved user experience.

Problems solved by technology

Consequently, most of such laser telemeters still have no data management system, or manage data in the simplest data export mode.
After detecting a natural gas leak in an area through measurement, inspection crew do not have the capability to complete a repair task alone in most cases, but require other technicians to work together for the repair task.
Because the frequency of the measuring laser beam is generally invisible, engineers face the problem of how to record the leak location.
When handling a task of finding and recording a leak point, the inspection crew need to perform multiple steps, which are time-consuming and difficult to operate.

embodiment 1

[0062]As shown in FIG. 1, this embodiment first provides a data management terminal 2 and a data management system that includes the data management terminal 2 and that is configured to manage a handheld laser telemeter. The data management terminal 2 is a personal digital assistance apparatus held by an engineer, and includes a first communication apparatus 202, a second communication apparatus 204, a processor 206, and a memory 208. The memory 208 stores a program to be executed by the processor 206, and can invoke the first communication apparatus 202 and the second communication apparatus 204 to transmit and receive data.

[0063]For convenience of illustration, FIG. 1 only shows a circumstance in which a server 3 corresponds to a laser gas detector 1 and a data management terminal 2. In fact, each server 3 may correspond to two or more data management terminals 2, and can manage and transmit the data. In addition, each data management terminal 2 may work together with different la...

embodiment 2

[0072]As shown in FIG. 3, this embodiment first provides a data management terminal 2 and a data management system that includes the data management terminal 2 and that is configured to manage a handheld laser telemeter (a laser gas detector 1). The data management terminal 2 in this embodiment is a smartphone, and includes a first communication apparatus 202 (a Bluetooth communication apparatus), a second communication apparatus 204 (a cellular mobile network), a processor 206, a memory 208, an image acquisition apparatus 210 (a camera), and a positioning apparatus 212 (a GPS positioning system).

Abstract

A data management terminal for a laser gas detector, and a data management method thereof are provided. The data management method includes: the data management terminal establishes a connection to a communication port of the laser gas detector, and obtains target gas concentration data in a target region through the connection; the data management terminal creates a target gas concentration log according to the target gas concentration data; and the data management terminal transmits the target gas concentration log to a server.

Description

BACKGROUNDTechnical Field[0001]The present invention relates to the field of laser telemetry, and in particular, to a data management method and data management terminal for a laser gas detector.Related Art[0002]A laser telemeter has been widely used as a natural gas leak detection apparatus. Based on wavelength modulation spectroscopy, the telemeter works according to the following basic principles: fixing a laser frequency near a specific absorption peak of methane, modulating the laser frequency at the same time, and perform detection according to correlation between a frequency modulation harmonic signal and a concentration of a target gas to obtain information about the target gas on an optical path.[0003]The laser telemeter may be configured to different types of products, such as a product of a gimbal type, a handheld type, or an unmanned aerial vehicle type. A gimbal-type laser telemeter is generally used to scan and monitor gas leaks in fixed areas (such as natural gas pipe...
