Problems solved by technology

However, in real work, for the convenience of equipment installation and data reading, the transmission signal end of the load cell is directly branched, and multiple devices are connected at the same time. This method forms a coupling, which is a source of mutual interference, resulting in signal distortion.
Furthermore, this connection method also violates the line connection standard, which will cause serious consequences.

Abstract

The invention discloses an intelligent sensing signal conversion device and an intelligent sensing signal conversion method. The intelligent sensing signal conversion device comprises a weighing sensor, a general packet radio service (GPRS), a terminal computer and an intelligent sensing signal converter, wherein the intelligent sensing signal converter is connected with the weighing sensor and used for receiving a millivolt signal produced by the weighing sensor, converting the millivolt signal into a standard signal and supplying the standard signal to an external acquisition device; the intelligent sensing signal converter communicates with the terminal computer through the GPRS and is used for outputting the converted standard signal to the terminal computer; and the terminal computer is used for recording and monitoring the standard signal which is transmitted by the weighing sensor and converted by the intelligent sensing signal converter. The intelligent sensing signal converter adopts a singlechip working mode, so that distortion is avoided during signal transmission, and the original signal can be retained; and furthermore, due to the identification function of the device, the sensitivity can be improved, and a pressure value can be calculated correctly.

Description

technical field [0001] The invention belongs to the technical field of load cell transmission signal conversion, and in particular relates to an intelligent sensor signal conversion device and method. Background technique [0002] According to the working principle of the load cell, there is only one access point at the transmission end of the load cell, and it can only be connected to one collector or only one instrument to collect the weight signal. However, in real work, for the convenience of equipment installation and data reading, the transmission signal end of the load cell is directly branched, and multiple devices are connected at the same time. This method forms a coupling, which is a source of mutual interference, resulting in signal distortion. Furthermore, this connection method also violates the line connection standard, which will cause serious consequences. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present inventio...
