Monitoring and remote control of hydropneumatic tank for supply of drinking water to multiple sanitaries

Abstract

This work consisted of remotely visualizing and controlling the status in real time of 2 variables: level and pressure, in a hydropneumatic process. This hydro-pneumatic process is formed in the first instance by a cistern, which concentrates drinking water coming from the general line of comapa and serves as a supply for the aforementioned process. This supply feeds water to the tank by means of 2 pumps operating alternately (main and secondary); said water is stored under pressure in the tank and by the same pressure added by the gravitational force, this liquid is provided to six sanitary installations, which contain multiple toilet bowls, urinals and bowls. The monitoring begins by digitally measuring the level and pressure variables through sensors and using wireless technology these signals are transmitted to the office of the head of the maintenance department of the Institution; where, with the design of a graphic interface displayed on a computer, the level and pressure that occur in the hydro-pneumatic process can be represented. In addition to monitoring physical variables, it is also possible to perform control actions to activate or deactivate the main and / or secondary pump, it is also possible to control the activation or deactivation of a pressure relief valve in the tank to avoid an unsafe condition of work and if necessary, it is also possible to lower the water level.
