A no-load durability test system for electric tools and garden tools

Abstract

The invention discloses a no-load durability testing system for an electric tool and a gardening tool and belongs to the technical field of automatic monitoring. The no-load durability testing system comprises an industrial personnel computer cabinet, an electrical parameter instrument cabinet, a wiring groove, a sensor and a camera. One end of the industrial personnel computer cabinet is connected with the electrical parameter instrument cabinet, the electrical parameter instrument cabinet is connected with the wiring groove, the other end of the industrial personel computer cabinet is connected with the sensor and the camera, a power source of electric supply is connected with the industrial personnel computer cabinet through a voltage regulator and a direct-current power source. According to the no-load durability testing system, a test can be started by plugging power plugs of the tested tools into a socket of the wiring groove, long-distance testing can be achieved, manual intervention is not needed, and safety is improved; a direct-current testing platform and an alternating-current testing platform are available, each platform can be provided with a plurality of stations, each station corresponds to one tested tool, all the stations are independent from one another, non-interference parallel operation is achieved, and the testing efficiency and the system adaptability are improved. An industrial personnel computer is used for completing control of tests, monitoring of data and safety protection, the whole process is automatic, and the no-load durability testing system for the electric tool and the gardening tool is intelligent and safe.

Description

[0001] technology neighborhood [0002] The invention belongs to the technical field of automatic monitoring, and in particular relates to a no-load durability test system for electric tools and garden tools. Background technique [0003] The no-load durability test is a key test to verify that electric tools and garden tools will not have electrical or mechanical failures that will impair compliance with the standard requirements during long-term and repeated running tests under no-load conditions. It is a key test for electric tools and garden tools. An important content in garden tool performance testing. However, during the testing process, cumbersome operations and excessive human participation are required, resulting in large experimental errors and unstable test performance. In the prior art, the repeated start and stop of the mower is realized by designing the cylinder to pull the engine pull rope and the brake pull rope.

However, during the test process, cumbersome operations and too much human participation are required, the experimental error is large, and the test performance is unstable

In the prior art, the repeated start and stop of the mower is realized by designing the cylinder to pull the engine pull rope and the brake pull rope. Although automation is realized to a certain extent, the test error is large, and the data cannot be monitored in real time and the test method cannot be changed. It cannot meet the test requirements, and this method may cause certain safety hazards during the test process due to frequent power on and off, short-term impact of the power supply and long-term measurement

[0004] In view of the above deficiencies in the no-load durability test of electric tools and garden tools, in order to improve the reliability and safety of the test, the following problems need to be solved: 1) Automatic control and testing: most of the existing testing technologies require human participation, The test error is relatively large, and it is an effective way to improve the test accuracy to realize the automatic control of the electric tool and garden tool test and the automatic judgment and recording of the test pass; 2) The diversity of test methods: the current test system has a single method, Generally, the test time and cycle mode cannot be adjusted, and the test flexibility is low; 3) The objects to be tested are diverse: there are many kinds of electric tools and garden tools, and their starting and stopping methods are also different. Existing test methods and devices can only be used for them One or several tested objects are tested, which is not widely applicable; 4) Various test parameters: various parameters to be tested in the no-load endurance test, including current, voltage, power, temperature, etc.; 5) Test parallelism : During the test, sometimes several objects to be inspected need to be tested together, requiring good parallelism and mutual non-interference; 6) Parameter record: The parameters obtained from the test need to be recorded together with other test conditions, which is convenient for production test reports and subsequent review; 7) Safety: During the test process, it is necessary to be able to view the status of the object under test in real time, and at the same time monitor the test environment in real time to complete early warning and prevention of safety problems such as short circuits and fires
