System security and control, also at distance through GSM module, of water supply, liquids and gas supply (of urban facilities for civil houses, cylinder, fixed gas cylinder) by opening and /or closing multiple automatic electromechanical valves. The management system is based on an electronic control divided into gas/ section and liquid section and a series of sensors, as presence detectors, detectors of gas and liquids, located in the most appropriate place and at the discretion of the user. As Regards as the valves related to gas section, these valves should be installed outside the house or working place to prevent that the escape of gas that could happen in the section of pipe located before the electronic valve, may spread inside the environment that is monitored, thus thwarting, in this way the installation and use of the system itself. Also for the water /liquid section, for the positioning of the electronic valve, we use the same principles made for the gas section. In any case for both gas / liquid sections it is advisable to install the valves outside the environment that we want to preserve in order to obtain the maximum security; but, of course, the user can install the valves where it seems appropriate for him/her and beneficial to the own needs. The user can control the various functions of the system through the central unit that is programmable with buttons START/ STOP that are inside the environment, or check the status of the system at a distance by a GSM module integrated within the central unit which can send messages of signals or alarm and receive instructions command and / or control. |
