Definitions
- the invention relates to a method for automatically checking the availability of a technical device in or on a building according to the preamble of claim 1 and a device for automatically checking the availability of a technical device according to the preamble of claim 7.
- a part of maintenance is usually the implementation of a diagnosis, by means of which it is determined whether the technical device fulfills all the intended functions as expected during operation.
- a test of the technical device is often carried out as part of such a diagnosis.
- a suitable command can be given to a controller of the technical device and a reaction of the technical device can then be registered and compared with a target reaction.
- the target reaction is the reaction that the respective command causes, provided that the technical device behaves as intended in accordance with its specification. Show the Diagnosis of a difference between the target reaction and the reaction actually registered following the command, this indicates a malfunction.
- the present invention addresses the disadvantages mentioned.
- the invention is based on the object of creating a method for automatically checking the availability of a technical device which is suitable for determining an impairment of the availability of the technical device during any period of time as quickly and reliably as possible, in particular during normal operation. Furthermore, the invention is intended to provide a device which is suitable for carrying out such a method.
- an automatic check of the availability of a technical device is implemented in that at least one test of the technical device is carried out under certain conditions, in which test at least one reaction of the technical device is registered and compared with a target reaction.
- a measured value is determined for the frequency of the course of the process for a first period of time. The test is only carried out if the measured value is lower by a predetermined amount than a predetermined value, which is either equal to a first estimated value for the frequency of the course of the process for the first period of time or equal to a second The estimate of the frequency with which the task expires is set for a second period of time. If the registered reaction matches the target reaction, it can be assumed that the technical facility is available. If the registered reaction does not match the target reaction, it can be assumed that the technical facility is not available.
- a usage model i.e. on the basis of a theoretical model that describes the way in which the technical device is used in normal operation and, if applicable, the expected behavior the user of the building and the influence of the users on the frequency of the operation.
- a usage model can be suitably selected depending on the situation.
- the invention is particularly applicable to checking the availability of technical equipment such as heating systems, air conditioning systems, ventilation systems, refrigerators, freezers and other household appliances, lighting systems, communication systems, information systems, reporting and alarm systems, devices for data or information processing, systems for data acquisition, Systems for access control in buildings, etc., provided that these facilities carry out at least one repeatable process.
- technical equipment such as heating systems, air conditioning systems, ventilation systems, refrigerators, freezers and other household appliances, lighting systems, communication systems, information systems, reporting and alarm systems, devices for data or information processing, systems for data acquisition, Systems for access control in buildings, etc., provided that these facilities carry out at least one repeatable process.
- compressors are operated discontinuously by means of a drive motor or a flow is controlled by a regulating valve or an actuator is brought into different positions as required.
- Activation of the drive motor or actuation of the valve or the generation of a control signal for controlling the drive motor or the valve or the actuator can be viewed as a repeatable process within the meaning of the invention.
- a target value temperature, humidity
- a control of the device reacts as expected .
- Devices for data or information processing usually carry out individual orders, which are processed manually or can be initiated by a controller, for example printing, copying or. Scan jobs.
- the processing of an order can be viewed as a repeatable process within the meaning of the invention.
- a command for processing a specified job can be given to a controller of the device by means of an automatic control. You can then check whether the device is executing the order as expected.
- the Fig. 1 shows an elevator system 1 with two elevators 1.1 and 1.2 of the same design in connection with a device 30 according to the invention for automatically checking the availability of the elevator system 1.
- This is installed in a building with six floors 3.1, 3.2, 3.3, 3.4, 3.5 and 3.6.
- a shaft 2.1 and 2.2 is provided for each of the elevators 1.1 and 1.2.
- x (x 1-6).
- the elevator 1.2 comprises a car 5.2 with a car door 6.2 on a side facing the floors 3.x, a counterweight 7.2, a support means 8.2 for the car 5.2 and the counterweight 7.2, a drive 10.2 with a drive pulley for the support means 8.2 and a Elevator control 15.2.
- the car 5.2 and the counterweight 7.2 are each connected to one another via the suspension element 8.2, the suspension element 8.2 wrapping around the drive pulley of the drive 10.2.
- Activation of the drive 10.2 causes the traction sheave to rotate and thus an upward or downward movement of the car 5.2 and the counterweight 7.2 in opposite directions.
- signals can be transmitted between the elevator controller 15.2 and various controllable components of the elevator 1.2 via a communication link 16.2.
- the elevators 1.1 and 1.2 can each be controlled independently of one another by the elevator controller 15.1 or 15.2.
- a communication link 18 is provided between the elevator controls 15.1 and 15.2. If necessary, signals can be sent via the communication link 18 be exchanged between the elevator controls 15.1 and 15.2 in order to be able to operate the elevators 1.1 and 1.2 as an elevator group with a group control.
- At least one of the doors is usually moved and / or the position of one of the cabins 5.1 or 5.2 is changed and / or a state of one of the drives 10.1 or 10.2 is changed and / or at least one Signal generated by one of the elevator controls 15.1 or 15.2.
- there is a use usually the presence of at least one person in the vicinity of the elevator system 1.
- measured values N m (i, t) for a frequency of use of the elevator 1.1 are determined as follows.
- the estimated values for the frequency of use would be independent of the index i, ie identical for all time periods ⁇ T (i).
- the measured values N m (i, t) for the frequency of use have no influence on the size of the corresponding estimated values.
- the parameter ⁇ in the function F (i, t, ⁇ ) accordingly determines the weighting with which a measured value N m (i, t) for a time interval ⁇ T (i) compared to estimated values of the frequency of use for the time periods ⁇ T (k) k ⁇ i influences the estimated value for the frequency of use N S (i + 1, t) for the following time period ⁇ T (i + 1).
- the estimated values for the frequency of use for consecutive periods of time can be adapted to current trends that change in the time dependency of the measured values for the frequency of use over several consecutive periods of time Show ⁇ T (k) with k ⁇ i.
- the above measures 1) -3) are carried out one after the other and then repeated. If no further use of the elevator 1.1 is determined up to the point in time estimated in measure 3), it can be assumed that the elevator 1.1 is not available. According to method B, under this condition the device 30.1 issues a command to carry out a test to the elevator control 15.1 and checks whether the elevator 1.1 shows a reaction corresponding to the expectations.
- step S30 it is checked whether the time t B of use lies in a time interval of duration ⁇ t at the end of the period ⁇ T (i), ie it is checked whether the condition t e (i) - ⁇ t t B t e (i) is fulfilled. If so, the method continues with method step S31 (path +). If not, the process continues with step S32 (path -).
- the duration ⁇ t can be changed as a function of the duration of the time period ⁇ T (i), for example in such a way that ⁇ t is always smaller than a certain fraction of the difference t e (i) ⁇ t 0 (i). In the course of the iteration, this leads to a dynamic adaptation of the method to changed conditions, for example if the frequency of use of the elevator varies greatly over time.
