Remote control display of test instrument and control method

Abstract

The invention belongs to the technical field of remote control of test instruments, and particularly relates to a remote control display of a test instrument and a control method. The remote control display comprises a wireless transmission module a capable of carrying out wireless information transmission with a wireless transmission module in the test instrument; and also includes a single-chipmicrocomputer for controlling the whole instrument, wherein the wireless transmission module a is connected with the single-chip microcomputer, a key combination module, an alarm, a liquid crystal display module and a voltage stabilization module are further connected with the single-chip microcomputer, the voltage stabilization module is connected with a control switch, and the control switch isconnected with a power supply module, the remote control display is used for carrying out remote control test on the test instrument, single-person and long-distance test can be realized, a test result is recorded, automatic alarm prompt when a safety threshold value is exceeded is realized, and the purposes of convenience and quickness in long-distance and large-batch data test can be achieved through the remote control display. And a safe, simple, convenient, efficient and accurate solution is provided for a special test occasion where a large batch of data is obtained through long-distanceand multi-point testing.

Description

technical field [0001] The invention belongs to the technical field of remote control of test instruments, and in particular relates to a remote control display for test instruments and a control method. Background technique [0002] The tester is a kind of testing instrument widely used in all walks of life. For different industries, the test data requirements of the tester are also different, but there are many occasions that require multi-point testing and large-scale data acquisition, and the test instrument itself has a large size, heavy weight, or a large range of test sites, long distances, test points and instruments. The situation where the location cannot be directly communicated brings great difficulties to the testing work. The following takes the electrical continuity of the grounding grid as an example to illustrate: [0003] The connectivity and electrical integrity between various grounding equipment and the main ground network, also known as electrical con...

AI Technical Summary

Problems solved by technology

The average test time for each conduction point is not less than 30S*2 people, and a complete measurement of a substation requires a lot of manpower and man-hours

[0012] Through the above examples, we found that there are the following problems in similar testing work: many people are needed, communication is inconvenient, efficiency is low, and there are problems in the test data that cannot be found in time. , Multi-point test is necessary for special test occasions where a large amount of data is obtained
