Abstract

Abstract Remote monitoring system with actuator and active controller The purpose of this system is to detect gas leaks in general, which may be: flammable, toxic or smoke that may occur in a certain environment, whether in a confined or open place, making the pre-established actuation in the programmable logic controller, which will communicate at a distance of the detected leak, informing the technical team, the problem located in the distribution line or fixed location, so that it moves and performs the repair and, In addition, it operates actively to prevent any accident by interrupting the passage of gas through the shut-off valves at the moment the leak is perceived.

DISTANCE MONITORING SYSTEM WITH ACTUATOR AND ACTIVE CONTROLLER [0001] The purpose of this system is to detect gas leaks in general, which can be: flammable, toxic or smoke that can present itself in a certain environment, being this in a confined or open place , performing the pre-established action in the programmable logic controller, which will perform the communication at a distance from the detected leak, informing the technical team, the problem located in the distribution line or fixed location, so that it moves and performs the repair and, in addition, operating actively so that it avoids any accident, interrupting the passage of gas through valves blocking the passage, when the leak is perceived.

[0002] It is known the existence in the state of the art of several security systems aimed at gas distribution networks, as for example, the document PI 1106204-5 deposited on 10/05/2011 and named “Leakage sensing device of gas, its use, gas leak monitoring and alarm system, process for its installation and / or maintenance ”referring to a plurality of remote gas leak sensor devices installed in specific points of underground distribution and transportation networks of energy, which are integrated with wireless communication systems. This network of sensors monitors the gas network, triggering an alarm in the event of a leak, providing the exact location of the accident, as well as maintaining a history of events. Despite having a good monitoring system, the object of this patent does not actively act on the problem, that is, it only communicates the problem to the technical team and

2/4 it will have to go to the site to assess and, if necessary, cut off the gas supply to avoid accidents.

[0003] Another document found is BR 20 2016 008251-5 deposited on 4/14/2016 and named “Active detector with automatic action against leaks of natural gas, LPG and carbon monoxide” which refers to a device formed by a gas detector coupled to a safety valve, which allows continuous and active monitoring, that is, in case of leak detection the system will block the source of the leak, reducing the risk of accident. However, there is no monitoring by a technical team, that is, anyone can reset the safety valve without solving the problem.

[0004] The present invention patent refers to a remote monitoring system with actuator and active controller, which in addition to monitoring, through sensors, the gas leak and notifying the technical team also includes an active controller that when informing the technical team instantly interrupts the gas supply at that point, thus reducing the risk of accidents. In addition to receiving leak alerts, the technical team can monitor all points via the web interface or mobile applications, and also remotely interrupt the gas supply when necessary.

[0005] The following description and the associated figures, all given by way of non-limiting example, will make the invention patent well understood.

[0006] Figure 1 represents a schematic drawing of the remote monitoring system with actuator and active controller, showing the interaction between its components.

[0007] The system comprises a gas detector and control device with mains connection (4), a blocking valve (3),

3/4 central server and interface (web and mobile application) for leak monitoring, consumption reading and manual passage blocking. For its operation it is necessary the supply of electric energy, which can come from the distribution network with AC / DC converter, energy generators and / or stored in batteries. This system can be applied to distribution networks, industrial installations, commercial installations and commercial installations; having high performance when installed in buildings, with sensors distributed inside consumer units and in the distribution network at strategic points. It can also detect leaks by monitoring the flow at different points, comparing the values and performing the equivalence calculations.

[0008] Gas detectors and control devices (4) are installed in environments to detect gas concentration and / or pipeline leakage, and when a hazardous condition is identified, it controls supply interruption through the blocking valve (3 ), at the same time it triggers an alert through network communication with a data center that sends the same to the technical team and the person in charge of the site through a web interface and / or mobile application.

[0009] The data center, through the web interface or mobile application, provides: extract of gas volume that passed through each blocking valve (3), the real-time reading of each gas detector and control device (4 ), history of gas concentration / leak readings, command to manually close the blocking valve (3) and command to reopen the blocking valve (3) if it has been closed manually (only available to the technical team).

4/4 [0010] The gas interruption will be carried out only at the point where it was identified as problematic, and if it is in a gas line, the equipment prior to the leak will be operating normally, or in buildings the interruption will be carried out only for the floor or apartment with problem.

[0011] Once the leak is detected, the blocking valve (3) can only be reopened manually by a member of the technical team, so that if the equipment is violated and the valve is reopened by an unauthorized person, it will close again , because in addition to the physical reopening, it must be done in the control software, available only to the technical team. While if the person responsible for the environment chooses to close the valve (3) manually for any reason, he may request the reopening of the same to the technical team through a call on the web interface or mobile application.
