The invention relates to an intelligent shunting signal transmission device in front of a data collector. The device comprises a data collector and is characterized in that the device also includes a shunt group and a counting circuit, wherein one end of the shunt group is connected with an input signal source and the other end is connected with the data collector through a signal line. The data collector is connected with the input terminal of the counting circuit through a control signal line, and the output terminal of the counting circuit is connected with the shunt group for transmittingmulti-path control signals. The device can automatically shunt large-batch signals when used for large-scale data collection, and the selected signals can be transmitted to the data collector according to the time and the functional requirement of the data collector, thereby greatly saving equipment cost, simplifying assembly and achieving high reliability of the collected data. The invention also includes a shunting signal transmission method in the intelligent shunting signal transmission device in front of data collector.
Description
technical field [0001] The invention relates to a data acquisition device, in particular to an intelligent shunt signal transmission device and a transmission method at the front end of the data acquisition device. Background technique [0002] In the prior art, a data collector is directly connected to a set of input signal data. When collecting multiple sets of signal data, a large number of data collectors are required to correspond to it. This equipment costs are high, installation is difficult, and signal data collection Low reliability. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent shunt signal transmission device and transmission method at the front end of a data collector. When applied to large-scale data collection, it can automatically shunt a large number of signals, and automatically select the path of the input signal, according to the data The time and function of the collector requires that the selected...
