Brief introduction of GPRS telemetry rainfall observation station

2022-03-07 16:41:39| Source:網(wǎng)絡(luò)| views:| 0

  GPRS telemetry rainfall observation station is composed of tipping bucket rainfall sensor, rainfall microcomputer collector, GPRS wireless data transmission module and solar power supply system. The rainfall microcomputer collector has the functions of automatic rainfall recording, historical data recording, data communication and so on. The rainfall electrical signal obtained by the tipping bucket rainfall sensor is transmitted to the rainfall microcomputer collector, which transmits the collected rainfall value to the data center computer through the GPRS data transmission module.

  Brief introduction of GPRS telemetry rainfall observation station

  Technical parameters of rain sensor:

  ※ measurement range: 0 ~ 4mm / min (it can work normally under the condition of < 8mm / min)

  ※ measurement error: ± 3% (test rain intensity 2mm / min)

  ※ resolution: 0.2mm

  ※ working temperature: 0 ~ 80 ℃ (sensor) - 40 ~ 80 ℃ (recorder)

  ※ water bearing diameter: φ 200mm 0.6mm outer edge angle 45 degrees

  ※ average storage interval: ※ 60.2ma

  The standby current of GPRS system is about 30mA

  ※ recording capacity: 524280 pieces

  ※ number of channels: 1 channel (can be extended to 15 channels)

  ※ recording interval: adjustable from 1 minute to 100 days

  ※ data interface: USB2 0 (GPRS wireless communication can be customized) when using GPRS mode, AC or solar battery power supply must be used

  ※ power supply: dry battery 9V, usb5 0V (default configuration) solar 6W 7.5ah solar power supply system 220V mains power (extended configuration, can be used at the same time!)

  ※ cable configuration: 2m national standard shielded wire (standard configuration)

  Functions and features of rainfall microcomputer collector:

  ※ this machine has small volume, simple operation and reliable performance. Whole process data tracking, long recording time, integrating data acquisition and recording, and data will not be lost after power failure.

  ※ low power consumption design. When powered by dry battery, the battery can be used for three months to one year at a time. The recording interval can be set arbitrarily from 1 minute to 100 days (it is recommended to set it above minutes, and the battery life is directly proportional to the interval length.)

  ※ high performance GPRS module is adopted, which makes the connection faster and the communication more reliable.

  ※ professional data processing, with functions such as low-power erasure protection, storage fault detection, data information recovery after equipment power failure, etc.

  ※ flexible and efficient power management, with hardware reverse connection and internal short circuit protection functions. It can be used in DC power supply, No. 5 battery, solar lead-acid battery and usb5 It works under the coexistence of 0V and other power supply modes.

  ※ the host computer software is presented free of charge, which can easily view or export data charts and support excel table storage. The software has a chart curve display component with 100000 times scaling ability, and has excellent ability to view curve trend and data details.

  ※ the collector communication mode can be configured flexibly. In addition to USB (UART) mode, it also accepts the customization of RS485 communication mode.

  matters needing attention:

  ※ this product can withstand wet environment and rain wash, but do not soak in water, otherwise it will cause damage to the equipment!

  Scope of application:

  It is widely used in agriculture, forestry and other fields, as well as reservoirs, dam security inspection, ports, meteorological stations and other places.
