The invention discloses a fast and high-precision photoelectric direct-reading intelligent water meter system, which is mainly composed of a plurality of terminal water meters, a meter reading concentrator and a meter reading management system. The unit includes a mechanical character wheel and multiple groups of light emitting and receiving pairs of tubes. The transmitting tube and receiving tube in each group of light emitting and receiving pairs of tubes adopts a unique corresponding orthogonal code sequence CDMA signal communication connection, and the orthogonal code sequence CDMA signal Each code also uses Manchester encoding to make it jump, and the single-chip microcomputer respectively drives the transmitting tubes of each group of light emitting and receiving tubes to send signals to the receiving tubes. The transmitting signal of each transmitting tube of the present invention is not a simple pulse signal with light or no light, but a selected orthogonal code sequence, and each code adopts Manchester encoding to ensure that each code has Hopping, eliminating the influence of environmental factors; while different transmitting tubes use different orthogonal code sequences, eliminating adjacent interference.
Description
technical field [0001] The invention relates to the field of water meters, in particular to a fast and high-precision photoelectric direct-reading intelligent water meter system. Background technique [0002] Water meters are important measuring instruments related to people's livelihood. In recent years, urban construction has developed rapidly, but the water meter industry has developed relatively slowly. With the development of microelectronics technology and information technology, the development of smart water meter technology has entered the fast lane, and various new technologies are emerging one after another. In summary, the development of smart water meter technology can be divided into three aspects: [0003] One is the improvement of measurement performance. Traditional mechanical water meters are equipped with moving measurement parts and mechanical counting (display) devices, which make it difficult to maintain the measurement accuracy and repeatability indic...
