Embodiment Construction

[0008] The invention is composed of a clock circuit, a voltage stabilizing circuit, a counting circuit, a communication circuit, a voltage detection circuit and a programming circuit. Describe the present invention below with reference to accompanying drawing:

[0009] The jumper J4 is closed, and it is connected to the positive pole of the power supply through the 2 pin of the voltage regulator chip U3 (7533), and a voltage VDD is output through the 3 pin of the voltage regulator chip U3 (7533), and VDD is the microcontroller U1 (C51) and the clock chip U2 (8563) to provide a suitable regulated DC power supply. The crystal oscillator X1 oscillates through pins 1 and 2 of the clock chip U2, and then U2 (8563) sends out a square wave signal connected to pin 6 of the single-chip microcomputer U1 (C51) through a differential circuit composed of R2 and C6 to provide a second pulse for the single-chip microcomputer U1 , to wake up once every second to ensure that the microcontroll...

Abstract

A system realizing bus data remote transmission and remote valve control relates to a system for effectively and reasonably distributing water resource, which is composed of a clock circuit, a stabilization circuit, a counting circuit, a communication circuit, a voltage check circuit and a programming circuit, wherein the stabilization circuit is a single chip, the clock circuit provides a stabilized direct current, the clock chip provides second pulse for the single chip, a magnetic sensor receives external magnetic induction information, the single chip stores corresponding data, a remote control signal enters into an interface J1 to be transmitted to the single chip, the single chip responses and sends out the data from the J1, and the control signal of the J1 triggers an electric valve. The invention can collect, transmit and discover network accidents on-time, use the communication circuit to transmit data from the measurer to the management PC, and use the interface to connect various charge management systems, to analyze data, realize effective management and distribution. The system can be networked in large scale to realize large-scale measurement. The system has low power consumption and long service life.

Description

technical field [0001] The invention relates to a system capable of effectively and rationally dispatching water resources. Background technique [0002] With the increasing scarcity of water resources, how to rationalize and dispatch the water resource system more effectively? With the instability and uncertainty of users' water consumption, how to design metering products scientifically and rationally? Has the leakage caused by management problems in the water supply process directly affected the economic benefits of the enterprise? Can the traditional water supply metering mode meet the needs of the development of the modern water supply industry with the increase of water charges? How to make meter reading data break through the limitations of time, place, distance and meter reading environment? How to avoid all kinds of water theft? How to minimize operating costs? How to discover and understand the fault information and operating status of metering equipment in ti...
