Description
Technical Field
The invention relates to an adjustment unit for adjusting at least one measured value of at least one measurement medium, an adjustment system for adjusting at least one measured value of at least one measurement medium, and a method for adjusting at least one measured value of at least one measurement medium.
Background
In the field of process evaluation, different types of sensors are used in order to obtain measured values for different measured variables, for example pH values, chlorine content, etc. In many processes, dosing agents are added to the process in dependence on the measured values that are known in order to keep the measured values within the desired range of values. What is important in this case is: by adding the dosing agent, the measured values are influenced as precisely as possible, and the addition of the dosing agent is kept as low as possible for economic, health and ecological reasons.
An example of such a process is the disinfection of public swimming pools. For disinfecting swimming pools, the free chlorine is fed to the water by means of a dosing unit, depending on the content of free chlorine measured by the sensor. Of course, in the case of measuring other measured variables, corresponding sensors are used together with suitable metering units.
Known disinfection apparatus regulate the dosing of free chlorine when the chlorine sensor knows that the measured chlorine content deviates from the desired chlorine value, for example, the free chlorine content in swimming pools should be between 0.3 mg/L and 0.6 mg/L (DIN 19643).
However, this regulation has the following disadvantages: when the sensor detects a deviation of the measured values, it is only found that the dosing agent needs to be added. The latency between the change in the measurement value due to the swimmer and the detection of this change by the sensor depends on various parameters (size of the swimming pool, distance from the sensor, pump power, etc.) and can be, for example, several minutes up to several hours. In any case, this latency time is undesirable, since the measured values may lie outside the desired range if the measured value deviations are corrected too late by the dosing unit.

The control unit also comprises an interference source information unit which is connected to the control unit and is set up to detect future interference starts and future interference strengths of the interference sources which change the measured values of the measuring medium and to transmit them to the control unit. The control unit is further adapted to: the release of the dosing agent by the dosing unit is controlled in dependence on the future disturbance start of the disturbance source and the future disturbance intensity such that the measured value of the measurement medium remains within the range of values.
By taking into account future interference onset and future interference strength, it is possible to: the dosing unit is controlled in a prospective manner such that the disturbance is optimally compensated at the point in time at which the disturbance starts.

Detailed Description
Fig. 1 shows a schematic illustration of a control system 100 according to the invention for controlling a measured value M of at least one measuring medium 1, having a control unit 10, a sensor 2 and a metering unit 3.
Of course, the regulating system 100 may also comprise a plurality of sensors 2, 2 'and a plurality of dosing units 3, 3', as shown in fig. 2. In this way, the measured value M of the measuring medium 1, for example of a swimming pool, can be adjusted independently of the measured value M of the measuring medium 1', for example of a non-swimmer pool.
The sensor 2 is connected to the control unit 10 in order to transmit the measured values of the measuring medium 1 to the control unit 10. The dosing unit 3 is connected to the regulating unit 10 so as to be controlled by the regulating unit 10. The dosing unit 3 is adapted to release a dosing agent D into the measurement medium 1 such that a measured value M of the measurement medium is influenced.
The adjustment unit 10 serves to adjust the measured value M of the measuring medium 1. The adjusting unit 10 comprises a control unit 12 and an interferer information unit 16.
The control unit 12 has a communication channel 14 which is suitable for connection to the sensor 2 in order to receive the measured values M of the measuring medium 1 detected by the sensor 2. The communication channel 14 is also adapted to be connected to the dosing unit 3. The communication channel 14 may be implemented by an electrical line, as shown in fig. 1. Alternatively, the communication channel 14 may be realized by a wireless connection, as illustrated in fig. 2 by radio symbols.
The control unit 12 has a memory 18. The memory 18 is adapted to record the information of the disturbance source information unit 16, the measured values of the sensor 2, the dosing of the dosing unit 3. The control unit 12 is adapted to control the release of the dosing agent D by the dosing unit 3 in dependence on the measurement value M of the measurement medium 1 detected by the sensor 2.
The memory 18 is also adapted to store an occupancy plan for the pool or calendar events. In one embodiment, the memory 18 stores an occupancy plan. The memory 18 is adapted to change the stored occupancy plan. The change may be made, for example, based on empirical values, such as a longer dressing time, too late in terms of a scheduled time window, and so forth.
In one embodiment, the memory 18 has a disturbance prediction, wherein the control unit 12 is adapted to control the dosing unit 3 in dependence on the disturbance prediction. The interference prediction includes, for example, weather data, vacation dates, occupancy plans, or statistical visitor times.
The control unit 12 has an online module 20. The presence module 20 enables the control unit 12 to access external databases or external information sources. The access is for example realized by a mobile data connection or by an internet connection. The presence module 20 is adapted to update the interference prediction in real time.
The interference source information unit 16 is connected to the control unit 12. The interference source information unit 16 is set up to detect a future interference onset T1 and a future interference intensity Z1 of the interference source 4, which cause a change in the measured value M of the measuring medium 1, and to transmit them to the control unit 12. In the described embodiment, the term interference source 4 refers to all factors which influence the measured value M of the measuring medium 1, such as for example swimmers and/or water sports.
The control unit 12 is further adapted to control the release of the dosing agent D by the dosing unit 3 in dependence on a future disturbance onset T1 and a future disturbance intensity Z1 of the disturbance source 4 such that the measured value M of the measuring medium 1 remains within a value range W, the value range W of the chlorine content of the combined chlorine in the swimming pool being, for example, less than or equal to 0.2 mg/L (DIN19643), the method for adjusting the measured value M being described in more detail below.
The interference source information unit 16 is set up to transmit identification information about the interference source 4 to the control unit 12 in order to identify the interference source 4. The control unit 12 is adapted to store the interference characteristics of the interference source 4 identified by the identification information in the memory 18. The interference characteristics include an interference start T1, an interference end T2, and an interference intensity Z1.
The control unit 12 is set up to control the release of the dosing agent D by the dosing unit 3 in dependence on the identification information, in particular in dependence on the stored interference characteristics. The interference source information unit 16 is, for example, a cash register of a swimming pool. The identification information is, for example, an entrance charging situation.
A method for adjusting the measured value M of the measuring medium 1 is described below.
Fig. 3 and 4 schematically show two exemplary time-dependent changes of the disturbance Z, the dosing amount D and the measured value M.
In a first step, a conditioning system 100 is provided. The sensor 2 is in contact with the measurement medium 1, and the dosing unit 3 is designed such that the measured value M of the measurement medium 1 can be influenced by the release of the dosing agent D.
In a next step, the sensor 2 detects a measured value M of the measuring medium 1. The measured value M is transmitted to the control unit 12 via the communication channel 14.
Next, the interferer information unit 16 knows at time T0 the future interference onset T1 and the future interference intensity Z1 of the interferer 4 that caused the change in the measured value M of the measurement medium 1. Therefore, the interference of the interfering source 4 known at time T0 has not yet acted on the measuring medium 1.
In the case where the interference source information unit 16 comprises a pool check-out desk, the pool check-out desk communicates to the control unit 12 each time a new swimmer enters the room. Since the swimmer will also stay in the changing room and in the shower after registering his entrance at the cash desk, a future disturbance start T1 can be expected in this case, for example, after about 15 minutes after entering the swimming pool. In this case, each swimmer would increase the interference intensity Z1. Similarly, the pool cashier notifies the control unit 12 when the guest leaves the pool (see fig. 3).
For the case where the aggressor information unit 16 includes access to a database with school lessons or sports clubs occupancy plans for the swimming pool, the aggressor information unit 16 learns the expected start of interference T1 due to the swimming group. Likewise, the interference source information unit 16 can know the interference strength Z1 by the number of swimmers per swim group. The aggressor information unit 16 can also evaluate the expected end of interference T2 (see fig. 4) for the swim group by means of the occupancy plan.
Subsequently, the control unit 12 evaluates the measured values M detected by the sensors, the future interference onset T1 of the interference source 4 and the future interference intensity Z1 of the interference source 4.
The control unit 12 then controls the dosing unit 3 in dependence on the evaluation such that the measured value M of the measured medium lies within the range W. The dosing unit 3 then releases the dosing agent D in the amount calculated by the control unit 12, so that the disturbance intensity Z1 due to the disturbance source is compensated for at the start of the disturbance T1.
As shown in fig. 3, dosing unit 3 is ideally controlled by control unit 12 in such a way that dosing agent D is released earlier than disturbance start T1 by latency Δ T. The latency Δ t is a period of time necessary until the sensor 2 detects a change in the measurement value M. The change in the measured value M due to the interference source 4 at the start of the interference T1 is therefore suppressed prospectively.
If the swimmer leaves the pool to take a shower and change clothes at the end of the disturbance T2, the end of disturbance T2 is registered at the cash register as time point T3 when the swimmer walks past the cash register and leaves the pool. The dosage of dosage D is therefore not matched again to the current number of visitors at time T3. Due to this time offset between T2 and T3, slightly more dosing agent D is released. This causes a slight change in the measured value M between the end of interference T2 and the point in time T3 (see fig. 3).
In the exemplary embodiment shown in fig. 4 for adjusting the measured value M, the interference end T2 of the interferer 4 is also detected by the interferer information unit 16 at time T0 and is communicated to the control unit 12.
The control unit 12 therefore takes this disturbance end T2 into account, which is accompanied by a correspondingly adjusted dosing of the dosing unit 3 for the dosing agent D. The metering is then already set at a latency Δ T earlier than the interference end T2. Thus, an optimum dosing can be achieved and the measured value M can be managed exactly like the desired measured value M0.
The interference start T1 and the interference end T2 may be given by, for example, the number of visitors statistically.
The disturbance variable 4 can also be rainfall above an open-air swimming pool. In this case, it is possible, for example: the interference start T1, the interference intensity Z1 at the interference start T1 and the interference end T2 are known from current weather data, which are called up, for example, via the internet.
Thanks to this regulation system 100, it is possible to: the consumption of the dosing agent D is kept as low as possible. In this way, operating costs can be saved and the desired measured value M0 of the measuring medium 1 can be optimally managed.
