Abrégé

In order to prevent a faulty diagnosis for a control valve having an electropneumatic position controller for controlling the position of a valve member, on the one hand the profile of the end position of the valve member is detected over time during operation. The deviation of the end position in each case from an expected end position can be determined therefrom. Furthermore, a histogram is recorded by means of the electropneumatic position controller during operation. The histogram is corrected by means of the determined deviation of the end position in each case. On the basis of the corrected histogram, a diagnosis for the control valve is generated and output. If necessary, a maintenance measure for the control valve is then initiated. The diagnoses are substantially more accurate due to the correction by determining the possibly changed end position of the valve member.

A method for detecting output-side leaks in a double cone air power booster is proposed. Initially, a reference curve is recorded which relates a control variable for the outlet pressure to the outlet pressure. During operation, at least one steady state is determined, wherein only steady states preceded by a drop in the output pressure of the double cone air power booster are considered. Values of the control variable and the output pressure belonging to the steady state are determined and compared with the reference curve. If the output pressure determined is smaller by a specified tolerance than the output pressure to be expected according to the reference curve for the control variable determined, an output-side leakage is determined. In this way, leaks in the consumer system connected to a double-cone air power booster, for example a pneumatic control valve actuator, can be detected in an uncomplicated manner, which can save costs for maintenance requirements that are detected too late. Additional components are not required.

The invention proposes methods and devices for suppressing noise (320) in a drive signal (w) for a position controller of a field apparatus for regulating fluids in a process engineering system. The method has the following steps: a) The extent of the noise in the drive signal (w) is determined. b) If the extent of the noise exceeds a first predefined threshold, the noise is reduced by a filter (310, 315). c) The filtered drive signal is transmitted (380) to the control loop. d) If the extent of the noise does not exceed the threshold, the unfiltered drive signal is transmitted to the control loop. A flexible reaction to a setpoint signal that is impaired by noise is provided as a result. If the noise becomes too great, a suitable filter is connected. A corresponding message (390) can also be output. The filtering takes place outside of the control loop so that the influence on control quality, response behaviour and stability of the controller remains as low as possible.

A method for preventing control-induced oscillations in a valve with a pneumatic actuator and position control with an integrating component, including the following steps: Checking whether oscillations of the valve member occur by counting the zero crossings or extreme values of the control difference. If oscillations were detected, it is checked whether they result from oscillations of the set point. If not, the dead zone is increased and/or the gain parameter is decreased. If no oscillations were detected, it is checked whether wear in the drive has exceeded a predetermined measure. If so, the dead zone is decreased and/or the gain parameter is increased. In this way, oscillations caused by the I-component of the control can be detected and stopped. Further changes to the parameters are only made when friction is expected to have decreased due to wear.

Abrégé

Methods for testing the operability of a safety valve, as well as a solenoid valve for triggering a safety valve, and corresponding devices are proposed. The safety valve has a solenoid valve which is used to vent the pneumatic actuator in a safety case. Initially, a safety case is triggered. The position course of the valve member is recorded, and the time required until the safety position is reached is compared with a reference value. From this, it can be reliably concluded whether the assumption of the fail-safe position was caused by the solenoid valve or by the positioner. The measured values of pressure sensors can also be taken into account and allow further diagnostics to be carried out if operability is not assured. If the result of the test is positive, maintenance intervals can be optimized.

Torque sensors (150) are used in rotary valves (100) to identify wear and malfunctions. To this end, they measure the torque exerted by a drive (140) with the aid of a coupling onto a rotatably mounted valve member of the rotary valve (100). Torque sensors (150) are subject to a drift of their zero point. To compensate for the drift, torque sensors (150) must be set into a load-free state and the zero point of the torque sensor (150) must be determined once more. Torque sensors (150) are generally subject to a load, however, during operation of a rotary valve (100). Within the scope of the proposed method, a load-free state is achieved during operation and is used for zero-point calibration of the torque sensor (150) by controlling the rotary valve (100) such that the play of the coupling is passed through. In this way, the calibration of the torque sensor (150) can be performed as needed or the drift of the torque sensor (150) can be compensated. Wear and malfunctions can thus be identified safely and reliably.

The invention relates to a method for detecting a spring breakage in a preloaded drive of a control valve. The method is based on the fact that the pressure which must be applied to achieve a certain valve member position falls significantly after the breakage or failure of the spring. The breakage of a spring in a preloaded drive can thus be detected reliably using the sensor system already present in the control valve, moreover without having to disrupt or interrupt operation.

Abrégé

The invention relates to methods and devices (100) for controlling a controlled variable of a controlled system (110) with a fluidic drive, in particular of controlled systems (110) with an excessive air output capacity. Controlled systems (110) with insufficient (fluidic) drive as regards the air output capacity are often controlled with the aid of rate limiters (170), which prevent overcontrol. If, however, the systems (110) have pronounced delays or hysteresis, a rate limiter (170) may often not prevent an overcontrol. Proposed for solving this problem are methods and devices with which delays or hysteresis are detected on the basis of changes in the actual value of the controlled variable and are taken into account in the rate limiting. In particular, the value of the air output capacity is used to quickly overcome states that are characterized by delays or hysteresis. As soon as the states have been overcome, the rate limiting is raised and is possibly even used for counter-balancing in order to prevent an overcontrol of the controlled system (110). In this way, not only overshooting but also dead times can be reduced.

An adapter for wireless data transmission, in particular according to the “Bluetooth Low Energy” standard, is proposed. The adapter has a cylindrical housing whose radius is at least twice its height. The adapter includes a wireless transceiver and a processor arranged in the cylindrical housing and connected to the wireless transceiver, and a data interface connected to the processor. The processor is arranged to drive the transceiver and the data interface and can therewith transmit data wirelessly. Because the adapter for wireless data transmission has a flat design, it can be retrofitted in valve positioners. This makes it possible to retrofit commonly used valve positioners that until now do not have an option for wireless transmission of their status data with this adapter. As a result, these commonly used valve positioners also achieve the capability of wireless transmission of their status data.

The invention relates to a method for detecting leaks at the outlet in a double-cone air power booster. Initially, a reference curve is recorded, which relates a control variable for the output pressure to the output pressure. During operation at least one stationary state is determined, wherein only stationary states are considered, which were preceded by a reduction of the output pressure of the double-cone air power booster. Values of the control variable and the output pressure, which belong to the stationary state, are determined and compared with the reference curve. If the determined output pressure is smaller by a predefined tolerance than the output pressure which is expected according to the reference curve of the determined control variable, a leak at the outlet is detected. In this way, leaks in the consumer system connected to a double-cone air power booster, for example a pneumatic control valve drive, can be detected in an uncomplicated manner, whereby costs incurred for maintenance requirements not detected in time can be saved. Additional components are not required.

The disclosure provides a method for testing a solenoid valve for triggering a safety valve having a single-acting fluidic drive and a positioner. The drive fluid pressure is increased by a first pressure difference. An attempt is made to switch the solenoid valve to the safety position. The drive fluid pressure is measured at a specified point in time that is selected such that the pressure in the drive fluid lowers at most by the first pressure difference. If the pressure in the drive fluid is higher than a reference pressure at the specified point in time, the functionality test of the solenoid valve is failed. The lowering of the pressure in the drive fluid is monitored over a defined period of time to make conclusions regarding the pressure generating system. The pressure does not fall below the operating pressure so the position of the valve member remains constant.

The invention proposes a method for diagnosing feed-air pressure fluctuations and/or leaks at the outlet in a proportionally controlled double-cone air power booster, by initially measuring a downstream step change in the control setpoint, repeating the measurement of a downstream step change, and diagnosing a feed-air pressure change if the reversal amplitude of the repeated measurement differs from the reversal amplitude of the initial measurement and/or diagnosing a higher leak at the outlet if the reversal duration of the repeated measurement is shorter than the reversal duration of the initial measurement. In this way, leaks in the consumer system connected to a double-cone air power booster, for example a pneumatic control valve drive, and changes to the supply pressure can be detected early on, meaning that costs incurred for maintenance requirements not detected in time can be reduced. Additional sensors are not required.
