Problems solved by technology

[0003] Due to the need to detect different working parts, in the past, it was necessary for personnel to manually replace the detection and switch detection lines, which was troublesome. When receiving radiation, due to the different models of the massage chairs to be tested, the range of radiation frequencies emitted is also different. Antennas in different frequency bands receive radiation. In the past, it was not possible to switch the circuits of antennas in different frequency bands. In the past, it was not convenient to automatically store the received radiation data, and it was automatically backed up.

Embodiment 1

[0024] The massage chair system uses EMC testing to identify the source of overrun problems. The specific working method steps are as follows:

[0025] Step 1: The power supply, EUT under test, line impedance stabilization network, EMI receiver, PLC processing module and NAS storage module are all set in the metal plate testing room, and are all grounded through copper wires;

[0026] Step 2: The EUT under test in the massage chair is connected to the line impedance stabilization network through the first circuit switching chip, and the connected EUT is selected. After the selected EUT is connected to the line impedance stabilization network, the signal sent After filtering in the line impedance stabilization network, the radiation signal is obtained;

[0027] Step 3: The radiation signal obtained in step 2 is received by the EMI receiver. When receiving, the second circuit detection chip can detect the current signal. When it is detected that the current receiving frequency b...

Abstract

The invention discloses an over-limit problem source screening method for an EMC test for a massage chair complete machine system. The specific working method comprises the following steps of 1, arranging a power supply, a tested EUT, a line impedance stabilization network, an EMI receiver, a PLC processing module and an NAS storage module in a metal plate detection chamber, and grounding through copper wires; and 2, connecting the tested EUT in the massage chair with the line impedance stabilization network through the first circuit switching chip, and selecting the connected EUT. According to the method, a detection circuit can be automatically replaced, detected and switched, operation is simple, efficiency is high, when radiation is received, antennas for receiving different frequency bands can be switched, the receiving effect is ensured, and received radiation data can be conveniently and automatically stored and automatically backed up.

Description

technical field [0001] The invention belongs to the technical field of massage chair testing, and in particular relates to a method for identifying the source of an overrun problem by using EMC testing for a complete system of a massage chair. Background technique [0002] EMC means that in the same electromagnetic environment, the equipment can work normally without being affected by the interference of other equipment, and at the same time, it will not interfere with the work of other equipment, including EMI, that is, electromagnetic interference, and EMS, that is, anti-electromagnetic interference. For convenience To detect whether the electromagnetic interference generated by the energized working parts of the massage chair machine exceeds the limit, so it is necessary to use the EMC test method to test the equipment. [0003] Due to the need to detect different working parts, in the past, it was necessary for personnel to manually replace the detection and switch detec...
