What we discussed here relates to an automatic vehicle barrier coming with a barrier column and a barrier boom, whereby the barrier boom can be swiveled on one side of the barrier column is arranged in an orderly manner and has no supports on the other end, whereby the barrier column is used to arrange the barrier arm pivoted about a horizontal axis bare barrier boom mount, as well as with a a motor drive for the barrier boom and one that interacts with the motor drive control device.
Vehicle barrier gate has a barrier pillar and a barrier boom. The barrier boom can be pivoted about a horizontal axis barrier column arranged and can consist of a closed position to an open position and vice versa be proceeded. The barrier boom is in a closed position, usually in a horizontal position. Located in the open position, the barrier boom is usually vertical position, that is in the direction of gravity aligned.
Automatic vehicle barrier gate described above can be found, for example, at entrances and exits from parking lots clearence, as barriers to customs or toll systems men or at railway crossings., etc.
For arranging the barrier boom on the the barrier column serving as a barrier boom holder. This is provided by the barrier column, and it can be pivoted about a horizontal axis educated. When fully assembled, the hinge takes the barrier boom on one side, that is, at one end, on. On the other end, the barrier boom is free of supports trained, which means there is no support for the cabinet provided, which is in the closed position of the barrier boom of the structural support of the the end of the barrier boom away from the column. The end of the barrier boom furthest from the column is perhaps more free-floating.
For proper pivoting, the barrier boom is powered by a motor drive. There is an electric motor, which is usually used as a syn-chronmotor is designed, and an electric motor downstream transmission. It is also a rule a safety clutch is provided, which is on the output side tig of the gearbox, i.e. connected downstream of the gearbox between the gearbox and the barrier boom mount, is arranged. The barrier boom is between one vertical open position and a horizontal position closed position moved by the motor drive, whereby the motor drive also serves to barrier boom in the horizontal closed position position in suspension so that there is no disturbance.
Reaching the end positions of the barrier boom, that is, reaching the horizontal closed position on the one hand and the opening reach the vertical open position on the other hand is detected using appropriate position sensors, which is on the motor shaft of the motor drive means on the transmission input side, or on the drive shaft the barrier boom holder, i.e. gearbox on the aisle side. The position sensors are micro switches, rotary value switches encoders or Hall sensors.
The signals detected by such position sensors. The measured values are sent to control electronics. Guided which follows the movement sequence according to the achievement the desired end position is completed, in- corresponding to that of the motor of the motor drive is regulated.
The ones that are usually present on the transmission output side. The clutch seen is a torque-switching system. Safety clutch designed to ensure that due to forces acting on the barrier boom large torques are transferred to the motor drive be led. This can be caused, for example, by obstacles caused in the travel path of the barrier boom. but also through vandalism. Typically is the clutch as a non-positive slip clutch or designed as a positive locking body coupling and slips when overloaded or bends at an angle according to which between adjacent form-fitting elements trained.
Although there are limitations to the above-described. This type has proven itself in everyday practical use. there is still a need for improvement. In particular, it will particularly viewed as disadvantageous is that in the case of an initial installation of the barrier requires adjustment. So the end position positions are determined by mechanical measurement lungs of the barrier boom and it is the connection between the end positions determined in this way positions and those recorded by the position providers to produce the desired values. This regulation represents one additional effort when installing the automated vehicle barrier system. Furthermore, this regulation is lost if it as a result of an impact on the barrier boom overload causes the safety clutch to slip. It is therefore based on the previous description, a vehicle boom barrier is consistent to propose a structure that simplifies handling exercise is permitted, especially during initial assembly. To solve this problem, a vehicle barrier gate system mentioned at the beginning is presented which are characterized by the characteristic features of claim 5.
The solution takes place a positioning device known from the prior art encoder specifies a measuring unit that provides a measuring device for storage recognition, in the form of a corresponding gyrometric sensor, preferably in conjunction with a win- sensor. Such a measuring device is used in the difference to a previously known position provider, to determine the absolute position of the barrier boom in the room grasp. So it becomes a departure from the state of the art not the relative position of the barrier boom opposite detected by a motor or drive shaft. The measuring device Rather, it serves to determine the angle of inclination between the Barrier tree and the direction of gravity to grasp, therefore the absolute position of the barrier boom in space.
This configuration has the advantage that regulation also during initial assembly or if the barrier is not required. Because of measurement technology no longer the relative position of the barrier boom detected relative to a motor and/or drive shaft no adjustment or adjustment is required. regulation, as in the manner described above constructions known to the prior art the case is. In addition, the one described above is also disadvantage eliminated that as a result of an overload conditional triggering of the safety clutch of a new The barrier regulation needs to be adjusted. A certain correct operation of the barrier remains unwarranted even after an overload. interruption possible.
The construction proves this makes it much easier to handle overall. ownership, both with regard to initial use commissioning as well as when re-commissioning following an overload accident.
The measuring device is according to another featur on the barrier boom or on arranged in the barrier boom mount. In case of a appropriate pivoting movement of the The measuring device therefore covers the barrier tree same pivoting angle as the barrier boom itself, so that the inclination of the barrier boom, that is, the orientation of the barrier boom is relative opposite the direction of gravity and/or the barrier column, can be recorded as a measurement variable can. The desired end position positions of the cabinet can be done precisely and without any calibration process be controlled. The control device delivers A comparison circuit is available for this purpose recurring comparison between predetermined ren target values on the one hand and measured actual values permitted.
The control device can also be designed in such a way that in the event of accidental or misuse overload in the direction of rotation of the barrier boom Overload initially gave way and when there was no overload and/or elimination of the overload of the barrier boom as- which is moved to the desired end position. This ensures that even after a trigger the safety coupling of the barrier boom into its position desired end position is moved as soon as the triggering obstacle is removed.
According to a further feature, it can be provided that the motor steps of the motor evaluate the motor belonging to the relevant drive and these against the signals supplied by the measuring device check plausibility. If the measured and the calculated waited change in position of the barrier boom is not exceeded agree, this indicates a possible defect in the barrier and a corresponding error may occur. message sent to a remote monitoring system become.
We propose a control device for the operation of a vehicle barrier system, with a barrier column and a pivotable one on the Barrier boom arranged on the barrier column, which is a a measuring unit with a measuring device for absolute measurement detection and a comparison circuit occurs, which are characterized by the characteristic features of the Proverb 1 distinguishes. Such a control device This is achieved using the method according to the invention Barrier described advantages.

In terms of procedure, it is provided that by means of a measuring unit of the inclination angle between the barrier boom and the direction of gravity is recorded. For this purpose, in the already existing a gyrometric measuring device in the manner described for use on the barrier boom itself or on the Barrier boom holder of the barrier column attached is ordered. This measuring device is a a sensor that is used in normal operation. The electro-mechanical vehicle barrier covers the same angle as the one barrier boom. This angle is determined by measurement grasps and sets the angle of inclination between the barrier tree and the direction of gravity.
The measurement unit records one actual signal corresponding to the inclination angle is generated and fed to a comparison circuit. Here you will find a equal between the actual signal, i.e. the measurement signal, on the one hand, and a predeterminable setpoint on the other. On the other hand, the target values are preferred- show the possible end position positions of the lock kenbaums is used, which means, for example, 90° for the vertical open position and 0° for the horizontal closed position of the barrier boom. In the course of carrying out the method which has already been explained above. The advantages explained above the limit.
