Overview
All NRL/RTU units routinely collect and log sensor data. NRLs then periodically connect to a central Neon comms and web server via an IP network and use a push data model to upload the logged data. The central Neon server can be cloud-hosted, virtual, or physical. The Neon server is offered as a Neon data-hosted service using a Unidata Neon server for a monthly fee. Otherwise, customers can purchase a Neon server license and run the Neon software on their own server. The Neon system receives, processes, displays, stores, and reports collected data in many ways. The Neon system also can issue control commands based on pre-set algorithms and issue alarms/notifications via several mediums. Alarm setpoints can be set up on the NRL/RTU unit itself as well as on the Neon central server. The alarm notifications can be sent via several methods, including email and SMS text messages. Alarm triggers can initiate physical actions in the field, such as turning pumps on and off or activating other control functions based on the internal program within the NRL/RTU.
The Neon system has fully bi-directional communications between the NRL/RTU units and the central Neon server. This allows for remote diagnosis, remote programming and remote firmware updating for the operation of the remote equipment, thereby reducing costly site visits. NRL/RTU units can be configured to read sensors, log data internally to local memory and push data to the central Neon server at user-settable intervals such as once a minute, every few minutes, every hour, once a day. Data to be viewed on the Neon Web server in near real-time from any browser and can be reported to other systems using email, FTP, and web services.
The 3001M Nano Logger was designed for use in boreholes of 100mm internal diameter and above, but it can be used whenever a smaller form factor logger is required. It can be configured to use either Cellular, NBIoT or Iridium SBD networks as its method of sending sensor data from the field to the Neon Server.
The 3001M Nano Logger connects to sensors in the field, collects readings from those sensors, logs the sensor data and transmits the collected data to a central server via a Cellular, LoRa or Satellite network.
The 3001M Nano Logger is programmed in the field with a Unidata standard program called a scheme. The scheme specifies how often and for how long the datalogger should collect data from the sensors and how often the data should be sent to the server. A wide range of sensor types is supported, for example, analog sensor, frequency counter, digital input as well as Modbus and SDI-12. The 3001M NRL Nano Logger comes with 2 x D cell Lithium batteries.
The 3901A Battery extender can be used to add additional lithium battery capacity to the 3001 Neon Remote Logger. Depending on the application, the scan rate, the log rate and the communications rate, this battery extender allows for up to 10 years of operation for the 3001 NRL. Sensors are connected to the logger via a custom-specified connector, allowing for easy removal of the logger if servicing is required.
