1 / 14 “ELECTRONIC DEVICE FOR INTELLIGENT MONITORING AND CONTROL OF LINEAR DISPLACEMENT VALVES” FIELD OF APPLICATION

[001] The present invention is contained within the technical field of intelligent monitoring and control devices, in particular in the field of application of diaphragm process control valves, being used in the industrial sector. More specifically, the present invention presents an electronic device for intelligent monitoring and control of linear displacement valves, specifically designed for applications with diaphragm-type linear valves, in which such device is fully configurable by means of magnetic buttons, being equipped with hall effect transducers for detecting a magnetic field generated by a magnet installed in the actuator. The device uses artificial intelligence to identify the behavior of the valve and send diagnostics, as well as using an accelerometer to monitor any vibrations that may indicate installation and operation problems of the equipment. DESCRIPTION OF THE STATE OF THE ART

[002] As is widely known among professionals involved in industrial application areas, one of the fastest growing fields, both in technology and importance, is that of intelligent valve monitoring and control. Intelligent valve monitoring stands out for its role in automation and control systems, allowing for greater effectiveness and precision in observing actuators and valves, functioning as the final control element in these devices.

[003] The most widespread technology for valve monitoring is the use of mechanical couplings, which have very complex adjustments and assemblies, low sensitivity and precision, and are often responsible for variations in processes, thus resulting in low stability and quality of controls. This type of conventional technology of Petition 870250008369, dated 01 / 31 / 2025, page 8 / 28 2 / 14 Valve monitoring largely utilizes limit switches, which are responsible for indicating whether the monitored valve is open or closed, being limited to these positions and unable to indicate the percentage of partial opening. This information is essential in many applications, as it can indicate variations in the working fluid pressure in the line during operation, valve malfunction, or control system malfunction.

[004] With the evolution of technologies, other forms of valve monitoring have been tested, such as the use of Hall-type sensors, as can be seen in patent document BR 10 2019 019079-5 - ELECTRO-ELECTRONIC DEVICE FOR THE MONITORING OF LINEAR DISPLACEMENT VALVES, the summary of which presents a device comprising a sensor (2), a solenoid valve (3) with electrical connection (4), wherein the operation of the sensor (2) is based on the detection of the position of an actuator, which is connected to the shaft (5) of an actuator, repeating in turn the up and down movement of a diaphragm when pressurized. The actuator shaft (5), as the valve opens, penetrates the core of a solenoid coil (6), altering the electromagnetic field formed inside it. The sensor (2) is provided with valve position signaling, highlighting the mechanical position signaling, with a yellow indicator (7), and internally, it has a spring (9) that rests on the mechanical signal (8) and the shaft (5), transmitting the upward movement of the shaft to the signal (8). It has 7 LEDs (10), which indicate, through the color of the emitted light, the open or closed position of the valve.It is equipped with three magnetic buttons (11), with two magnetic poles north (12) and south (13) to promote the actuation of the magnetic buttons and a signaling display (14).

[005] Another document that deals with the subject is document BR 10 2016 024422-6 - ELECTRONIC DEVICE FOR Intelligent valve monitoring and control, the summary of which... Petition 870250008369, dated 01 / 31 / 2025, page 9 / 28 Figure 3 / 14 presents an electronic device consisting of a plastic enclosure (2) with a transparent cover, said device (1) having an electrical connection (4), pneumatic connections (7), means for connection to a diaphragm valve, means for controlling the opening and closing of said diaphragm valve by compressed air, electronic boards (3), a plurality of Hall sensors (3a, 3b, 3c, 3d, 3e) and a magnet (8) coupled to the actuator shaft of said diaphragm valve. By means of integrated software, the device (1) monitors the intermediate positions between the fully closed and fully open positions of said diaphragm valve.

[006] Finally, another solution present in the state of the art can be observed through patent document BR 10 2019 014 322-3 ELECTRONIC DEVICE FOR INTELLIGENT MONITORING AND CONTROL OF ROTARY VALVES, whose abstract presents an intelligent electronic device for the intelligent monitoring and control of rotary valves, capable of performing exact and continuous measurements of the positions of these valves through the use of a Hall effect encoder positioned just above the valve axis, in order to monitor all its states, from the "fully closed" position to the "fully open" position, including also the intermediate positions of partial opening of the valve.

[007] However, even with the solutions contained in the state of the art, it would benefit from the advent of a new electronic device for the intelligent monitoring and control of linear displacement valves, specifically diaphragm-type valves, in which such a device is fully configurable by means of magnetic buttons, possessing automatic calibration capability, continuous detection technology, Hall effect transducers for detecting the magnetic field generated by a magnet installed in the actuator, a high-speed microprocessor for reading the magnetic field absorbed by the Hall effect transducers, converting it into a precise and reliable signal regarding the valve's position; communication by various types Petition 870250008369, dated 01 / 31 / 2025, page 10 / 28 4 / 14 of protocols such as: PNP with I / O link, ASI3.2, ASI5, DeviceNet and Profinet network protocols; use of artificial intelligence to identify valve behavior and send reports; use of an accelerometer to monitor any vibrations that indicate installation and / or operation problems of the equipment; use of resin to protect the electrical part of the device; internal pressure sensor to monitor the pressure of the inlet pneumatic line and a second internal pressure sensor to monitor for possible diaphragm rupture; and a humidity sensor to monitor air quality in the pneumatic line.

Petition 870250008369, dated 01 / 31 / 2025, page 13 / 28 7 / 14 DETAILED DESCRIPTION OF THE INVENTION

[0021] In accordance with the objectives presented, the present invention relates to: “ELECTRONIC DEVICE FOR INTELLIGENT MONITORING AND CONTROL OF LINEAR DISPLACEMENT VALVES”, which presents an electronic device (1), designed to perform the monitoring and control of linear displacement valves, specifically diaphragm-type valves. The electronic device (1) comprises a main body (2), modular, comprising a base for connections (3), a central housing (4), an electronic module (5), a solenoid coil (6) and a valve body (7), all of which elements, when assembled, form the main body (2).

[0022] The connection base (3) is the lower portion of the main body (2) of the electronic device (1), preferably made of plastic, and said connection base (3) is the part responsible for attaching the electronic device (1) to the diaphragm valve to be monitored, wherein this attachment is made by means of screws (30).

[0023] The connection base (3) has, on its front portion, at least one and up to two PG13.5 type cable glands (31), screwed into the connection base (3) itself. The connection base (3) also has, in its interior portion, a central opening in which there is a magnetic actuator (32), which has a magnet. This magnetic actuator (32) is the element that follows the movement of the diaphragm valve, and its movement is responsible for generating a magnetic field through the magnet.

[0024] For better attachment to the diaphragm-type valve, the connection base (3) can use an adapter disc (10), which is intended to facilitate the attachment of the screws (30) to the diaphragm valve, when it has holes other than 35 mm. Petition 870250008369, dated 01 / 31 / 2025, page 14 / 28 8 / 14

[0025] The connection base (3) receives the input and output wires and / or cables, responsible for communication with the control system, through electrical signals controlled by a programmable logic controller (PLC). These cables are connected to the electronic device (1) by means of cable glands (31). The electronic device (1) uses PNP point communication with I / O Link, ASI3.2, ASI5, DeviceNet and Profinet network protocols.

[0026] Above the connection base (3), the electronic device (1) comprises a central housing (4), constructed of metallic material, wherein said central housing has a central opening that communicates with the central opening of the connection base (3), and through this central opening, the magnetic actuator (32) performs its linear movement, following the movement of the diaphragm type valve.

[0027] Inside the central housing (4) are housed the Hall-type transducers, elements responsible for detecting the magnetic field generated by the magnet fixed to the magnetic actuator (32). The operation of the electronic device (1) occurs through this variation in the magnetic field generated by the magnet fixed to the magnetic actuator (32), so that the Hall-type transducers can identify the magnetic field and send this information to a high-speed microprocessor installed in the electronic module (5). Also in the central housing (4), there is a window (40), which allows visualization of the movement of the magnetic actuator (32) inside the said central housing (4), where this window (40) performs the function of a mechanical position indicator for the diaphragm-type valve.

[0028] In its upper portion, the central enclosure (4) has electrical connectors (41) responsible for transmitting the signals captured by the Hall-type transducers, relating to the variation of the magnetic field resulting from the movement of the magnetic actuator (32). Petition 870250008369, dated 01 / 31 / 2025, page 15 / 28 9 / 14

[0029] Affixed to the rear portion of the central housing (4), the electronic device (1) comprises a solenoid coil (6) and a valve body (7), wherein the solenoid coil (6) is mounted inside the central housing (4) for protection against weather conditions, and protected by the valve body (7), mounted on its rear portion. The solenoid coil (6) is a 3 / 2-way type valve, with 1 / 8” NPT or BSP connections, and its main function is to control the magnetic actuator (32) in its linear movement, for the self-calibration of the electronic device (1). For this self-calibration, the solenoid coil (6) receives a signal to open and close a pneumatic actuator, which in turn moves the magnetic actuator (32) which, in turn, moves the diaphragm type valve.

[0030] Through this self-calibration cycle, the electronic device (1) can identify the positions corresponding to the opening and closing points of the diaphragm valve, as well as the respective opening and closing times. Three, five, or ten cycles can be performed to perform the self-calibration of the electronic device (1).

[0031] The command for the solenoid coil (6) can be carried out by means of magnetic switches present in the electronic module (5), by means of electrical signals sent by the control system, via cables connected to the cable glands (31) or by means of a specific application for this purpose, controlled by a smartphone, which communicates with the electronic device (1) via Bluetooth.

[0032] This self-calibration procedure of the electronic device (1) presents a number of advantages, among which the following stand out: it does not require opening the central housing (4) and also the control of the solenoid coil (6) by means of the magnetic switches and the application. Petition 870250008369, dated 01 / 31 / 2025, page 16 / 28 10 / 14

[0033] The valve body (7) of the electronic device (1) is preferably constructed of aluminum or stainless steel and has a box shape and is fixed to the rear portion of the central housing (4). Said valve body (7) has a connection for pneumatic power supply, as well as two pressure sensors, one sensor for checking the external system pressure and one sensor for checking the internal pressure of the electronic device (1). The valve body (7) also has a humidity sensor to monitor the air quality in the supply line.

[0034] The external pressure sensor present in the valve body (7) has the function of monitoring the pressure of the inlet pneumatic line and detecting any leaks, assisting in the monitoring of the industrial process in which the diaphragm valve is included. In turn, the internal pressure sensor has the function of monitoring any rupture of the diaphragm of the diaphragm valve and informing the control system of this event. This type of monitoring is very useful, since it prevents overpressure of the internal chamber of the electronic device (1) and its possible breakage. In this sense, the internal pressure sensor acts as an electronic safety fuse.

[0035] The valve body (7) has signal communication with the electronic module (5), ensuring the transfer of signals relating to the self-calibration of the electronic device, as well as the information collected by the internal and external pressure sensors, enabling the said electronic module to issue alerts when necessary.

[0036] The electronic module (5) is located in the upper portion of the central enclosure (4) and has electronic connectors in its lower portion, for communication with the electronic connectors (41) of said central enclosure (4). For the operation of the electronic module (5) and the electronic device (1) as a whole, a 24 Vdc power supply is required, provided by the control system. Petition 870250008369, dated 01 / 31 / 2025, page 17 / 28 11 / 14

[0037] The electronic module (5) comprises at least one high-speed microprocessor, an accelerometer, magnetic buttons and a color TFT (Think-Film Transistor) graphic display, all electronic components present in the electronic module (5) being fully sealed by means of resin, making the electronic device (1) suitable for explosion-prone applications, in accordance with international IEC and UL standards.

[0038] In the electronic module (5), the high-speed microprocessor is assisted by an artificial intelligence system, which helps in learning and identifying the behavior of the diaphragm valve. This learning of the diaphragm valve's behavior enables the accurate sending of diagnoses, which may refer to faults in the electronic device (1), faults in the diaphragm valve, and even faults in the valve's power supply line.

[0039] The accelerometer in the electronic module (5) is intended to monitor any vibrations in the diaphragm valve or in the electronic device (1), vibrations which may indicate possible problems in the installation or operation of the device and the valve. This data is also reported to the high-speed microprocessor and may be the subject of reports.

[0040] The magnetic buttons present in the electronic module (5) have the function of configuring the operation of the electronic device (1), as well as assisting in the control of the solenoid coil (6) regarding the self-calibration cycles. For this purpose, the magnetic buttons require the proximity of a magnetic switch, in which such switch has a north pole and a south pole, in which the actuation of these magnetic buttons occurs through the approach of one of the poles of the magnetic switch.

[0041] The electronic module (5) has a TFT color graphic display in its upper portion, which enables communication with the operator. The graphic display shows information regarding Petition 870250008369, dated 01 / 31 / 2025, page 18 / 28 12 / 14 the current position of the diaphragm valve, which can be: open, closed or half. The graphic display can be configured to show at least one of the following options: line pressure, total duty cycle count, partial duty cycle count, network address, alert code, percentage of diaphragm valve opening, temperature and days worked.

[0042] The graphic display can also show nine types of functional alerts, as shown in Table 1. Table 1 - Functional alert codes. A1 Minimum displacement alert due to minimum displacement less than XX mm during calibration. A2 Time limit alert due to exceeding the time limit for valve calibration. A3 Self-calibration failure alert due to different values ​​from the hall reading in each maneuver. A4 Out of range alert when the valve exceeds the open or closed point by XX mm. A5 No movement alert due to lack of valve movement. A6 Command failure alert when the valve does not execute the solenoid command. A7 Change alert due to an unexpected state change. A8 Safe mode when the monitor is not in safe mode. A9 Overpressure when the inlet pressure exceeds 9 bar. Petition 870250008369, dated 01 / 31 / 2025, page 19 / 28 13 / 14

[0043] The graphic display can also show fifteen types of operational alerts, as shown in Table 2. Table 2 - Operational alert codes. A11 Partial counter when the partial count is reached A12 Total counter when the total count is reached A13 Day alert when the set day is reached A14 Date alert when the set date is reached A15 Opening time when the opening time is exceeded A16 Closing time when the closing time is exceeded A17 High pressure when the inlet pressure is above the specified range A18 Low pressure when the inlet pressure is below the specified range A19 High voltage power supply above 32V for AS-Interface network and 10% for PNP and DeviceNet A20 Low voltage power supply below 27V for AS-Interface and 22.8V for DeviceNet and PNP A21 High temperature when the monitor temperature is above 70°C A22 Temperature when the monitor temperature is below - low 20°C A23 Solenoid short circuit when the solenoid coil is short-circuited A24 Solenoid open circuit when the solenoid coil or its cable is broken Petition 870250008369, dated 01 / 31 / 2025, page 20 / 28 14 / 14 when any of the PNP outputs or their A25 Output loads are short-circuited.

[0044] Based on this configuration, the electronic device (1) stands out as an excellent alternative for monitoring and controlling diaphragm-type valves, since it allows precise identification of the percentage of opening, using Hall technology, as well as advantages in terms of self-calibration, fault identification, and the issuance of reports and alerts. Another advantage of the electronic device (1) is that, by combining Hall technology with processing from a high-speed microprocessor, aided by artificial intelligence, it enables continuous monitoring of valves with excursions between 3 and 50 mm, accurately detecting movements of up to 0.1 mm, with a 16-bit resolution.

[0045] It should be understood that the present description does not limit the application to the details described herein. Although specific terms have been used, such terms should be interpreted in a generic and descriptive sense, and not for the purpose of limitation.
