Embodiment 1
[0018] A kind of smart water meter based on the Internet of Things of this embodiment, such as figure 1 Shown: including microprocessor, LCD display, flow sensor, wireless communication module, solenoid valve, solenoid valve drive module, intelligent gateway, monitoring center; said microprocessor is connected with flow sensor, LCD display, wireless communication module, electromagnetic The valve drive module is electrically connected; the wireless communication module communicates with the monitoring center through an intelligent gateway; the flow sensor includes a control module, a digital-to-analog conversion module, an ultrasonic transducer, and a signal conditioning circuit connected in sequence; the signal conditioning The circuit is also connected to the microprocessor.
[0019] The signal conditioning circuit includes a voltage amplifier circuit, a band-pass filter circuit, a self-gain amplifier circuit, and an analog-to-digital conversion module connected in sequence;...
Embodiment 2
[0024] This embodiment is further optimized on the basis of embodiment 1, such as image 3 As shown: the solenoid valve driving circuit is mainly formed by connecting a transistor Q1 and a relay K1. The solenoid valve drive circuit composed of triode and relay not only has a simple structure, but also has high control precision and is very practical.
[0025] The wireless communication module is a ZigBee module. The ZigBee module is used here because compared with similar wireless technologies such as WIFI and Bluetooth, the ZigBee module has the characteristics of low power consumption, short delay, and high reliability, and has a large network capacity, which can accommodate more than 60,000 node devices. It is suitable for use as a sensor network, the cost is not high, and it has a very high cost performance.
[0026] The control module is an FPGA minimum system module, and the FPGA minimum system includes a chip EP4CE10E22C8N, a reset circuit electrically connected to th...
