Energy measuring instruments and the management of data at the Valeriano Bécquer School

The project includes the installation of a PLC in order to centralise the storage and sending of data at the preschool and primary school Valeriano Bécquer (Seville).

 

 

This PLC has the capacity to store data and carry out signal integration prior to this data being sent to the server. The data lines that will connect to the various instruments installed will run from here, without affecting other connections which may be present at the school. Moreover, the PLC will mean it may be consulted and programmed remotely by the network. 


In order for it to function correctly, the following instruments have been used:
 

  • A network analyser to measure voltage, current, active power and reactive power.
  • A diesel flow meter with a pulse emitter to accurately measure circulating volume.
  • Four temperature and humidity sensors which measure outside temperature and humidity and three stations at the school. Each sensor emits a series of signals which are collected and processed by the PLC.
  • A calorimeter based on an ultrasonic signal to measure the speed of the water in the pipes and two temperature probes. This is equipped with a card to emit pulses of energy collected by the PLC in order to record it.
  • A water network metre with a pulse emitter. The pulses (these may be configured every 1 / 10 / 1000 l) will be collected by the PLC, which will record the volume of water used by the school.
