Thermal issues: ECS Parameters, Sensors and Telemetry Modules List

Last updated July, 2020

ECS Parameters

The Víctor M. Blanco 4-meter Telescope Environmental Control System has more than 80 parameters (Table 1) collected by more than 69 sets of sensors (Table 2)  and 27 ethenet telemetry modules (Table 3). The telemetry system is located from Glycol Pumps to the very top of the Blanco dome.

Several sensors (or instruments)  can be connected to one ethernet telemetry module, and one sensor can measure one or more parameters.

The parameters are air temperatures, surface temperatures, fluid temperatures, humidity, air pressure, oil pressure, glycol flow, voltages and more.

A Python script runs on the telemetry machine getting sensor data from the telemetry modules and sending to the MariaDB database server for ECS (Fig 1).

The data is updated every minute on DB tables and it is displayed on web depending on the area of Blanco Telescope (Fig 2).
