The water, electricity and gas multifunctional information collector comprises a main micro-control unit, wherein the main micro-control unit is connected with 485 communication circuits, a wireless data communication circuit, a data storage circuit, a clock circuit and a GPRS module respectively; the 485 communication circuits comprise an uplink 485 communication circuit and a downlink 485 communication circuit; two paths of downlink serial port inputs are composed of the downlink 485 communication circuit and the wireless data communication circuit and are used for collecting metered data of a water meter, an ammeter and a gas meter which have different protocols; and two paths of uplink serial port outputs are composed of the GPRS module and the uplink 485 communication circuit used for 485 field monitoring and cascading equipment.
Description
technical field [0001] The invention relates to an information collection device, in particular to a multifunctional information collection device for water, electricity, and electricity consumption. Background technique [0002] Traditional user metering instruments (water meters, electricity meters, gas meters) are usually managed by various management departments sending people to the meter installation site to read meters. Due to the wide range of users and large volume, errors are likely to occur. [0003] With the continuous improvement of construction and residential conditions, people's requirements for intelligent living facilities are increasing. At the same time, the power management department also requires changes to the traditional manual door-to-door meter reading due to the management needs of data statistics and charging. With the development of modern electronic technology, the rapid progress of communication technology and computer network technology provi...
