Constant-flow bubble type automatic water level measurement method

Номер: CN0101586979A
Принадлежит:

The invention belongs to the field of sensor measurement, and in particular relates to a method for automatically measuring water level by adopting a constant-flow bubble type water gauge, which comprises the following steps: measuring vertical height difference H of two ports of an air duct and mounting height h0 of an air exhaust; inputting a gravity acceleration g, the height difference H of the two ports of the air duct and the mounting height h0 of the air exhaust into a data acquisition device through a register; acquiring a pressure output value P0 of the constant-flow bubble type water gauge and a gas temperature T in the duct by the data acquisition device in fixed time; and acquiring a pressure output value PA of a barometer by the data acquisition device in fixed time. The invention provides the method more accurate than classic pressure water level relation conversion formula, and discloses that the vertical height difference of the two ports of the air duct is the main reason ...

ZIGBEE-technology-based micro-power consumption wireless data collector

Номер: CN0102201158A
Принадлежит:

The invention discloses a ZIGBEE-technology-based micro-power consumption wireless data collector, which comprises a data collector, wherein a ZIGBEE wireless adaptor control unit is connected to the data collector; ZIGBEE wireless adaptor collection units are arranged near sensors; and data interaction between the ZIGBEE wireless adaptor control unit and the ZIGBEE wireless adaptor collection units is carried out by a built-in ZIGBEE-technology-based wireless module. The ZIGBEE-technology-based micro-power consumption wireless data collector provided by the invention provides a wireless collection solution to sensor data collection which is not suitable to adopt a wire transmission way in a micro-area range and reduces the construction cost of a newly-built telemetry station or an elongated cable. The control unit and collection units are dormant usually, so the power consumption is reduced. Due to the built-in ZIGBEE-technology-based wireless module, the device volume is reduced, the ...
