Description

[0001] The invention relates to a maintenance system for a gate device, wherein a control device is provided which includes a motor control unit for controlling a drive device for driving a gate element and a non-temporary memory for storing gate data, wherein the gate data can be retrieved from the non-temporary memory.

[0002] Such a maintenance system is known from DE 10 2015 102 405.5. This allows for the simple maintenance of a gate system, without requiring on-site access to the gate or maintenance data. However, such a maintenance system is still limited to a "malfunction" in which part or all of the gate system has failed, or to a regular maintenance interval, at which point, ideally, it is determined that the gate is functioning correctly. Despite the storage of gate data, it is not possible to perform a so-called diagnostic check of the gate system that would prevent "malfunctions" or "failures" early and thus in a timely manner.

[0003] The invention is therefore based on the objective of providing a maintenance system for a gate device that provides a diagnosis of the gate device and thus a kind of early warning system for possible damage.

[0004] This problem is solved by a maintenance system according to the invention in that at least one temperature sensor is provided which is arranged in the area of ​​the drive unit, wherein the temperature sensor continuously determines temperatures T n as further gate data transmitted to the non-temporary storage of the control device, wherein an evaluation unit is provided which records a temperature profile f over preset operating cycles. n (T n ) created, whereby a comparison of a number of temperature profiles f n (T n) allows conclusions to be drawn about the need for maintenance of the gate mechanism. The temperature of the drive unit provides information about all moving parts, such as the drive unit itself, the gearbox, the gate leaf, and the associated bearings. In particular, a steadily increasing temperature profile over several consecutive operating cycles can indicate possible defects in the gearbox unit, gate leaf guide, or suspension, which are easy and inexpensive to repair before a sudden malfunction of the gate mechanism occurs.

[0005] It is particularly advantageous to provide at least one temperature sensor on a heat-conducting housing part of a housing of the drive device.

[0006] A particularly compact and therefore easy-to-retrofit system is provided by integrating the evaluation unit into the control unit; however, it can also be connected to an existing control unit as a retrofit unit.

[0007] Advantageously, several temperature sensors are provided. Preferably, the housing components on which the temperature sensors are arranged can be a motor housing component, a bearing housing component, and / or a gearbox housing component. This allows for faster and easier fault localization.

[0008] To eliminate the seasonal influence on the evaluation of temperature trends f n (T n To exclude ) an ambient temperature sensor, an ambient temperature sensor may be provided to measure the ambient temperature.

[0009] In a particularly advantageous embodiment of the invention, further sensors, such as at least one vibration sensor, at least one microphone, and / or at least one electronic nose, are provided in the area of ​​the drive unit, thereby enabling even more precise diagnostics. In particular, when a microphone is used, further microphones can be provided to filter out background noise.

[0010] Advantageously, the at least one temperature sensor is attached to the housing of the drive unit by means of a mechanical clamp. Alternatively or additionally, the at least one temperature sensor can be attached to the thermally conductive part of the housing using a thermally conductive adhesive.

[0011] In a particularly advantageous embodiment of the invention, a central maintenance data storage unit is provided, which contains maintenance data for configuring, monitoring, and / or modifying at least one control unit. This central maintenance data storage unit can, of course, be directly connected to the control unit. Alternatively, a mobile maintenance device can be provided, which can be connected to the non-temporary storage unit of the control unit via a bidirectional first data connection for the purpose of maintaining the gate device. The mobile maintenance device can be connected directly or indirectly to the central maintenance data storage unit via a bidirectional second data connection. This makes it particularly easy and quick for a technician to download the current maintenance data during a maintenance procedure. Incorrect work due to a lack of information available to the technician can be prevented.Furthermore, "maintenance data" is immediately forwarded to a central maintenance data storage system of the manufacturer. Access to the gate data or maintenance data does not necessarily have to take place on-site. In this context, the definition of the mobile maintenance device should be understood to mean that, from a control perspective, it is not part of the central maintenance data storage system.

[0012] The gate data can include, for example, a serial number, a gate position, a gate type, a number of closing cycles, hardware information, a fault message and / or operating states of a gate device.

[0013] Advantageously, the engine control unit and the non-temporary memory can be designed separately, ensuring that the gate data required for diagnostics or a maintenance procedure is not overwritten.

[0014] The invention is explained in more detail below with reference to a preferred embodiment and the accompanying drawing. This drawing shows: Fig. 1. A schematic view of a maintenance system for a gate device according to the state of the art. Fig. 2 a schematic side view of the drive unit Fig. 1, and Fig. 3 a schematic diagram of different temperature profiles.

[0015] Fig. Figure 1 shows a schematic view of a maintenance system for a gate device 1. A control unit 2 of the gate device 1 includes a motor control unit 3 for controlling a drive unit 4, which, for example, lowers and raises a gate element 5, a non-temporary memory 6, and an evaluation unit 7. Gate data from the gate device 1 is stored in the non-temporary memory 6, which is separate from the motor control unit 3. Possible gate data includes, for example, a serial number, a gate position, a gate type, a number of closing cycles, hardware information, a fault message, or operating states of the gate device 1.

[0016] The gate data stored in the non-temporary memory 6 can be read directly from the central maintenance data storage 9 or from a mobile maintenance device 8, such as a laptop, smartphone, or tablet PC, via a first bidirectional data connection 10. A radio transmitter / receiver 12 is provided in the control unit 2 for the first bidirectional data connection 10. Alternatively, a USB connection can also be provided. However, the normal maintenance cycle could potentially be made more efficient if the gate device communicated data directly to the central maintenance data storage. This would allow immediate action to be taken to prevent a gate device failure. Furthermore, if the maintenance data is known to the technician before the maintenance work is carried out, necessary spare parts could be carried directly by the technician during on-site maintenance activities.However, the following description assumes, as an example, a readout by the mobile maintenance device 8.

[0017] The mobile maintenance device 8 is connected to a central maintenance data storage system 9 via a second bidirectional data connection 11. The maintenance data storage system 9 is located, for example, on a server of a gate manufacturer and contains a large amount of maintenance data from various gate devices. Using the second bidirectional data connection 11, gate data read from the non-temporary storage 6 by the mobile maintenance device 8 is forwarded to the central maintenance data storage system 9, modified by the mobile maintenance device 8, and stored as maintenance data in the central maintenance data storage system 9.

[0018] Similarly, maintenance data stored in the central maintenance data storage 9 can be transmitted from the central maintenance data storage 9 to the mobile maintenance device 8 via the first bidirectional data connection 10 and via the second bidirectional data connection 11 and stored in the non-temporary storage 6.

[0019] The maintenance of a gate device 1 can now proceed as follows: First, a technician establishes a bidirectional connection between the mobile maintenance device 8 and the non-temporary storage device 6. The gate data stored in the non-temporary storage device 6 is then read. A unique reference to the maintenance data stored in the central maintenance data storage device 9 can be established using the gate device's serial number. The current maintenance data is then downloaded to the mobile maintenance device, allowing the read gate data to be compared with the predefined maintenance data, and the technician can begin the necessary maintenance work. Alternatively, the comparison of gate data and maintenance data can also be performed in the central maintenance data storage device. The read gate data can also be transmitted to the central maintenance data storage device 9 for documentation and later analysis.

[0020] It is also conceivable that the mobile maintenance device 8 is indirectly coupled to the central maintenance memory 9 by means of a second data connection between the control device 2 and the central maintenance memory 9, whereby the mobile maintenance device 8 is initially coupled to the control device 2 via the first data connection 10. An indirect connection can, of course, also be established by the mobile maintenance device 8 being connected to the control device 2 via the bidirectional data connection 11 and via the aforementioned second data connection between the control device 2 and the central maintenance memory 9.

[0021] Control device 2 is shown here only schematically. It can be composed of several components, including those intended to be independent of one another, such as sensors, circuit boards, and actuators. For further understanding, reference is also made to DE 10 2014 103 456.

[0022] Fig. Figure 2 shows a schematic sectional view of the drive unit 4. Fig. 1. The drive unit 4 consists of an electric motor 13, the rotating shaft 14 of which drives a sprocket (not shown) and thus the gate mechanism 5 via a worm gear 15 in a known manner. The rotating shaft 14 is supported in a multi-part housing 17 of the drive unit 4 by means of a bearing arrangement 16.

[0023] In the present embodiment, four temperature sensors T1, T2, T3 and T are used. U (for the ambient temperature) and a vibration sensor S SchProvided for, which transmit further gate data to the non-temporary storage 6. The temperature sensor T1 is arranged on a thermally conductive housing part 19 of the electric motor 13 by means of a mechanical clamp 18. The temperature sensors T2, T3 are provided on a housing part 20 in the area of ​​the worm gear 15 and the bearing assembly 16 by means of a thermally conductive adhesive 21. The temperature sensor T is attached to a non-thermally conductive flange part 22. U Attached for ambient temperature.

[0024] The temperature sensors T1, T2, T3 and T U as well as the vibration sensor S Sch continuously transmit data to the non-temporary storage 6. In predefined operating cycles, which can of course be changed at any time, temperature profiles f1, f2, f3 and f are recorded in the evaluation unit 7. U depending on the temperatures T1, T2, T3 and T U (see here) Fig.3) determined. Trends are also determined based on the data from the vibration sensor, but these are not explicitly shown here.

[0025] A comparison of the individual curves provides information about possible changes in temperatures due to friction or other disturbances, which are not currently significant, but could ultimately lead to the failure of the drive unit 4. QUOTES INCLUDED IN THE DESCRIPTION
