Embodiment 1

[0030] The present invention provides a technical solution: a communication tester for the problem of call echo, including a rectangular casing 1, by placing the prototype to be tested in the rectangular casing 1 and pushing it to the right, the inner wall of the rectangular casing 1 The left and right limit slides are connected with a rectangular briquetting block 2, the right side of the rectangular briquetting block 2 is fixedly connected with a baffle plate 3, and the opposite side of the baffle plate 3 and the rectangular sleeve 1 is fixedly connected with a tension spring 4, so that the rectangular briquetting block 2 will Carry baffle plate 3 to carry out integral right after overcoming the elastic force of extension spring 4.

[0031]The upper surface of rectangular briquetting block 2 is fixedly connected with fixed seat one 5, and the inwall of fixed seat one 5 is connected with rotating arm 6 by pin shaft rotation, and the top of rotating arm 6 is connected with fixe...

Embodiment 2

[0057] It is basically the same as the first embodiment, except that the second piston plate 32 is a rectangular piston plate, and the liquid storage cylinder 31 is a rectangular sleeve matching the second piston plate 32. Refer to Figure 7 , through the cooperation of the rectangular piston plate and the rectangular sleeve, the vertical lifting of the second piston plate 32 and the transmission arm 33 will be more stable, and the liquid in the liquid storage cylinder 31 will be ejected efficiently and stably.

[0058] Working principle: When the communication tester for call echo is used, the prototype to be tested is placed in the rectangular casing 1 and pushed to the right, so that the rectangular pressing block 2 will bring the baffle 3 to overcome the tension spring 4 Carry out overall rightward movement behind the elastic force, under the rotation cooperation between fixed seat 1 5, rotating arm 6 and fixed seat 2 7, lift pipe 8 will be with sealing cover body 10, rubbe...

Abstract

The invention discloses a communication detector for a call echo problem, and the detector comprises a rectangular sleeve, the inner wall of the rectangular sleeve is slidably connected with a rectangular pressing block in a left-right limiting manner, the right side of the rectangular pressing block is fixedly connected with a baffle plate, and the opposite sides of the baffle plate and the rectangular sleeve are fixedly connected with a tension spring. A first fixing seat is fixedly connected to the upper surface of the rectangular pressing block, a rotating arm is rotationally connected to the inner wall of the first fixing seat through a pin shaft, and a second fixing seat is rotationally connected to the top of the rotating arm through a pin shaft. According to the invention, through the cooperative use of the structures, the existing communication equipment call echo detection method mainly comprises the following steps: calling the detected communication equipment by using the communication equipment through manual operation (or machine simulation), and judging whether the detected communication equipment has echo or not through human ears (or software simulation). The detection method essentially belongs to a black box test, and the test can be carried out only after the whole machine is completely assembled, so that many inconveniences exist.

Description

technical field [0001] The invention relates to the technical field of detection technology of communication equipment, in particular to a communication detection instrument for the problem of call echo. Background technique [0002] Communication equipment is a general term for communication equipment installed in a certain area to transmit radio wave information, mainly divided into wired communication equipment and wireless communication equipment. Wired communication equipment mainly introduces solutions to serial communication on industrial sites, professional bus communication, industrial Ethernet communication and conversion equipment between various communication protocols. Wireless communication equipment is mainly wireless AP, wireless bridge, wireless network card, wireless lightning arrester, antenna and other equipment. In daily life, the most contacted communication devices are highly integrated communication devices such as smartphones and smart watches; thei...
