In general, the indicator light can intuitively reflect the test results, and the display can objectively display the test results in text form. The various ways of displaying the test results also improve the user experience, which is convenient for the staff to quickly and conveniently conduct operations at high altitudes. Learn about test results on feeder terminal equipment.

In order to further reflect the test results, the tester also includes alarms respectively connected to the controllers, and the alarms are used to send out alarms when triggered by the controllers; the alarms include buzzers. Once the test results show that the function is not normal, the alarm will send out an alarm such as a buzzer, so that when the staff is testing the feeder terminal equipment at high altitude, when there is a problem with the relevant functions of the feeder terminal equipment, the staff can pass the alarm. Quickly understand abnormal working test results without looking at the indicator light or display.

In order for the staff to retrieve the test results conveniently later, the tester also includes memory devices respectively connected to the controllers, and the memory is used to store the test results so that the staff can retrieve and record them later.

Of course, the tester can also include a self-tester connected to the controller, and a self-test switch is arranged on the main panel; Check operation, and then ensure that the tester can work normally, and provide further guarantee for the subsequent normal test of the feeder terminal equipment.

Specifically, the processor includes multiple internal circuit pins, and the multiple internal circuit pins are respectively matched with multiple pinholes of the aviation socket. The specific internal circuit pins can be 26. The internal circuit is designed for the 26 pins of the cable aviation plug one by one.

Carry out corresponding functional tests on the feeder terminal equipment, and understand the test results through indicator lights, etc.

Embodiment three:

For Embodiment 1 and Embodiment 2, the embodiment of the present invention provides a specific and simple implementation method. Specifically, the housing of the portable tester is provided with a one-way function switch button, an indicator light (light-emitting diode) and an aviation socket ; Inside is a small single-chip microcomputer with simple design, with self-powered power supply (3V). Wherein, the small single-chip microcomputer is equivalent to the integration of the controller and the processor in the foregoing embodiments, and can perform functions such as the controller and the processor.

Specifically, through the internal circuit pins of the 26 pins of the cable aviation plug, the design is defined one by one in advance, and the program is edited so that the indicator light on the outside of the tester shows whether the signal of a certain circuit is smooth and correct. Since the tester provided by this embodiment is equipped with a self-check function, before use, the self-check switch of the tester can be turned on. If the functions of each circuit of the tester are normal, the indicator light will be on in a cycle. If the tester itself has If there is a fault, the indicator light will stop and stay on for the corresponding function. When in use, the tester can work at heights, carry a test cable, insert the test cable into the aviation socket of the feeder terminal unit (FTU), and connect the other end of the test cable to the aviation socket of the tester. There are two ways to test the FTU. The two types are (1) after turning on all the function buttons (opening, closing, energy storage, and non-energy storage) on the tester, operate the internal mechanical structure of the FTU to judge whether the circuit is normal, (2) turn on each tester one by one Test the function buttons on the When the test circuit connection signal is normal, the indicator light is on, otherwise it is judged that the function of the FTU is malfunctioning.

In summary, this embodiment provides a portable tester and test system for feeder terminal equipment.
