Definitions
- the present invention relates to a method for Control of the swing angle of a by means of a multi-phase motor, preferably asynchronous motor, pulse-shaped powered swinging church bell.
- the object of the present invention is to create of a method which mentioned this above Does not have the disadvantage of the previously known methods, i.e. in which, in addition to the drive motor, no additional ones Swing angle scanners can be mounted have to.
- This task is accomplished using a method according to Claim 1 solved according to the invention.
- a 3-phase asynchronous drive motor 1 for the vibrating drive of a church bell 2 via a motor isolator 3 with a 3x 400V Power control 4 connected.
- the latter is used for pulse-shaped control of the drive motor 1 for Achieve a swinging deflection of the on one Glockenjoch 5 fortified church bell 2.
- Motor isolating stage 3 is used to protect the drive motor 1, in which after a certain number of failed attempts, where the desired or required Swing angle ⁇ was not reached, the drive motor 1 is decoupled from the power control 4.
- the church bell 2 in a known manner by short-term pulsed switching on of the drive motor 1 in the corresponding direction of rotation up to a stop of the clapper 6 on the bell 2 required swing angle ⁇ rocked up, and for further ringing the bell 2 swinging over this swing angle ⁇ held.
- the one required for a correct ringing process Target time between the two reversal points of the swing direction the bell is physical and therefore known for every bell ringing design.
- pulse-shaped operating times of the drive motor 1 is now new according to the present invention during the idle time phases of the drive motor 1, during which the latter is disconnected from the network, used as a generator, with the help of the generated measuring voltage between two successive reversal points of the
- the actual time required for the swing direction is calculated with the Target time compared, and if necessary, each short switch-on time of the drive motor in the Power control 4 corrected accordingly.
- This pulse train (see Figure 4) is then (still with drive motor 1) disconnected from the mains, e.g. comparator 12 consisting of a standard comparator fed, in which due to an upper and an lower threshold, on the one hand, the maximum voltage the impulses unified, and on the other hand for preservation clearly defined pulse gaps m in the reversal point of the from Decoupled, rotating drive motor 1, below a lower threshold Pulses are eliminated so that at the output of the Comparator 12 an approximately rectangular pulses having pulse sequence according to Figure 5, which enables evaluation by means of a microprocessor.
- comparator 12 consisting of a standard comparator fed, in which due to an upper and an lower threshold, on the one hand, the maximum voltage the impulses unified, and on the other hand for preservation clearly defined pulse gaps m in the reversal point of the from Decoupled, rotating drive motor 1, below a lower threshold Pulses are eliminated so that at the output of the Comparator 12 an approximately rectangular pulses having pulse sequence according to Figure 5, which enables evaluation by means of a microprocessor
- the threshold value of the comparator 12 can be over a e.g. drive motor adjustment consisting of a trimmer 13 on the used or existing Drive motor 1 can be adjusted.
- the rectangular pulse sequence obtained in this way (FIG. 5) is then fed to an optocoupler 14 for potential isolation and display of the motor measurement pulses, and then to an evaluation circuit 15 provided with a .RISC processor.
- the reversal point t o is determined in the middle of the pulse gaps m, at which the drive motor 1 comes to a brief standstill, the actual swing time is determined between two successive reversal points, compared with the desired swing time, and if one falls below or falls below one determined threshold value, the drive pulse duration of the drive motor 1 via the control 16 of the power stage 4 and the isolating stage 8, corrected accordingly.
- the display unit 17 serves to measure the measured pulse gap durations m to be displayed visually in order to show different Motors despite the same evaluation electronics at the Adjust the initial commissioning of the system optimally can.
