At present, during measurement, manual operation is abandoned in most scenes and precision measurement equipment is used, but in the existing measurement equipment, one piece of equipment has a plurality of channels, and because the channels generally share one interface to transmit data, the average single channel transmission rate is lower, the experimental effect is influenced, and even some experiments cannot be carried out. For example, if a device has 64 or more channels, the device utilization efficiency is low, and one instrument can be used by only one project person at the same time. If a multi-channel customization scheme is employed, customization costs are high.
The prior art solution uses a MT6420 device like our, with 64 or more channels for one device. Because multiple channels generally share one interface to transmit data, the average single channel transmission rate is low, the experimental effect is influenced, and even some experiments cannot be carried out. A device with 64 or more channels may have a less efficient device utilization. One instrument can be used by only one project person at the same time. If the project group only needs to use a part of channels, the rest channels are in an idle state, the equipment utilization rate is not high, and other colleagues of the colleague project group cannot perform experiments. One device has 64 or more channel schemes, if a plurality of project groups need to be used simultaneously, because the price of multiple channels is expensive, only one set of channels can be purchased in one laboratory generally, and the channels are used in different time, so that the experimental efficiency is influenced. However, when the concurrent networking mode can realize the multi-channel test, more channels can be realized by combining; after the disassembly, a plurality of project groups can be simultaneously used separately, and the utilization rate of equipment is improved. Or a multi-channel customization scheme is used, but customization costs are very high.
