Description

Gate control with wireless service interface The invention relates to a Gate control, using a wireless transmitter / receiver unit for service purposes can operate.

Under the term "service purposes" are used in this Related all processes understood that for Service and maintenance purposes are necessary on a door control, such as configuring operating parameters, the Reading error logs, counter readings or other diagnostic data, the import of new software (software update) and the giving of and stop commands.

at usual today electronic gate controls, it is necessary a variety of Enter parameters to the gate control, for example, in the Commissioning at the local Adapt conditions and the operating behavior accordingly the customer's wishes to configure. So can for example, driving speeds, specifications for braking and acceleration points, breakpoints and time intervals or the Control of signaling devices can be configured on the controller. But it is also possible Retrieve error logs or counter readings or a modified software to transfer to the gate control.

During the Commissioning or maintenance work must be done to the user as well to be possible, to set the gate in motion and stop again so that he can perfect function of the door and the settings made by it can check.

at Some state-of-the-art gate controllers are used for the listed operations already used different techniques, however, each more or less big Have disadvantages or require special, usually more expensive equipment, which the user is carrying must, and specifically for developed and produced the application at the gate control become.

To the State of the art belong for example, gate controls equipped with a display are and about Keys attached to the gate control itself or to the gate, configure. For this, the user usually has to first one Enter a special key combination before entering a configuration menu. There he can talk about more or less structured menus for the individual configuration parameters navigate and change them or display fault memory.

These However, the type of configuration has the disadvantage that it is not possible is, previously created configuration records in the gate control too program. Furthermore, a transfer is a new software version also not possible. Moreover, it is not possible to Read content from fault memory or other diagnostic data and store electronically in order to take them with them for further evaluation.

Other belonging to the prior art gate controls are equipped with connectors, over which a temporary Wired connection to a service and maintenance device made can be. For example, the wired connection may be by a serial interface according to the RS232 or RS485 standard Act, but there are other electrical or optoelectronic Known connections.

disadvantage This wired technique is that either the complete casing the gate control or at least a cover of the connector open before the user can connect a service and maintenance device, what often difficult, because the door control, for example, difficult to reach is mounted or constantly Dirt and moisture is exposed. Furthermore, the freedom of movement of the user through the cable length limited.

at other known gate controllers, these are connected to remote systems. Here is the gate control over a converter, for example, a modem, directly with a wired or wireless telephone network and can be connected from an external point be called to perform service and maintenance.

In similar Way are also known gate controls, which in a local wired or wireless network. As standardized network technologies are listed here by way of example Ethernet (IEEE 802.3), WLAN (IEEE 802.11), CAN bus (Controller Area Network) or EIB (EN50090).

Door controls With remote maintenance technology have the disadvantage that the needed converter for a gate control partly relatively expensive. Furthermore, for most service and maintenance anyway a fitter will be on site to the actual Behavior of the gate to observe and judge.

In another known technique, the gate controller is equipped with a wireless opto-electronic transmitting / receiving unit which operates, for example, in the infrared range. An example of this technique is the standardized Infrared Data Association (IrDA) known. The service and maintenance device is then equipped with a similar optoelectronic transmitting / receiving unit, and the operation can be carried out without contact via an optical path.

disadvantage This technique is that during the entire operation, which can take several minutes, one Visual connection between the gate control and the service and maintenance device exist got to. As from the daily Dealing with remote controls for televisions is known, heard To use this technique a certain target reliability of the fitter and the structural conditions and the installation location of the door control need the Enable the use of technology. Especially with gate controls in heavily polluted environment operated, this technique is not reliable.

at Another known technique for the configuration of gate controls Radio modules are used in the gate control, for example operate with a transmission / reception frequency of 433 MHz, and over the the gate control for Maintenance and service purposes can be served. Because for this Technology no commercial Terminals or HMI devices available are, must each time consuming for the Application developed as a maintenance and service device for the door control and are produced, which makes the devices relatively expensive and little flexible. Furthermore, exist for the frequency ranges, on which these radio systems work, only inadequate definitions, which make sure that other radio systems use the same frequency range use the data transfer Do not disturb or make impossible an adjacent radio system.

The The technical problem underlying the invention is that specify a gate control, in which the operation for service purposes by means of a fail-safe, commercial, standardized and inexpensive technique he can follow without that this the case the door control are opened must, and without a line of sight between gate control and User must exist and that allows extensive configuration records or comfortably transfer new software versions to the gate control, and to read out extensive data from the gate control.

Is solved this problem by a gate control with wireless service interface, in which the service interface as a radio interface with at least a transmitting and receiving unit is formed, wherein the radio interface according to the Bluetooth standard or the Near Field Communication standard (NFC) or according to the ZigBee standard is.

The Gate control according to the invention is advantageously equipped with a commercially available radio system, too the also commercially available equipment as maintenance and service devices be used.

It is according to the invention provided that when using the Bluetooth technology on the gate control, as with all other subsequent embodiments with other standardized transmission systems, the transmitting / receiving unit in the gate control always ready to receive is as soon as the gate control is supplied with electrical voltage. To carry out Of service and maintenance, it is therefore sufficient with the service and maintenance device in the sphere of action of the transmitting / receiving unit of the door control to step in to carry out the necessary work.

In another possible embodiment is the gate control with a radio system according to the Near Field Communication Standard (NFC) equipped on the license-free frequency range of 13.56 MHz works and ranges up to approximately 0.1 m at a data transfer rate of up to 424 kbps.

advantage this embodiment is the low price of the needed Components and the relatively simple feasibility, since the NFC transmission technology strongly based on the ISO / IEC 14443 standard, which already for widely used RFID systems.

As a commercial mobile service and maintenance device for the NFC technology, in particular offer mobile phones, which already often with equipped with an NFC transceiver. But other commercially available portable computer systems are provided as a service and maintenance devices.

In another possible embodiment the door control according to the invention this is equipped with a radio system according to the ZigBee standard, which operates in the frequency range of 868 MHz or 2.46 GHz and a range of up to 100 meters at a data transfer rate from 20 to 250 kbit / s.

advantage this embodiment is next to the big one potential Range even the rugged transmission technology, the for the networking of electrical appliances and sensors is designed.

Regardless of the transmission technology used in the radio system, it is provided that commercially available modules can be used at the gate control, which operate either according to the Bluetooth standard, according to the Near Field Communication Standard (NFC) or according to the ZigBee standard and for gate control electrical interface, for example, according to the I ² C, the RS232 or another standard, have, and in which the power supply of the module is carried out by the gate control.

These embodiment has the advantage that the development effort for the integration of the modules is low and high flexibility is guaranteed, because the change on another radio system only to replace the respective module is.

In an alternative embodiment be the components that for the respective radio system, which according to the Bluetooth standard, the Near Field Communication Standard (NFC) or the ZigBee standard, necessary, completely in integrated the electronics of a door control.

These embodiment has the advantage that the unit cost of the radio system compared to a modular design lower are.

In order to it is ensured that the door control according to the invention is not unauthorized Third, who enter the detection range of the gate control, the Can manipulate the configuration of the door control or other unauthorized Perform actions can, is in a further advantageous embodiment, a device provided in addition to by the transmission method anyway provided security mechanisms a single or multi-level system of permission levels provides. Access to the permission levels is granted only after one for each permission level individual permission query, for example by querying a password or an access code.

A Multi-privilege device has the advantage of that user groups with different permissions on the gate control can be set up. Thus, for example, user groups are possible, which only read out allowed by error logs and / or counter readings is and other user groups, for example, the configuration change the gate control allowed to.

There provided according to the invention is, as a service and maintenance device, a commercially available mobile Computer or a commercial one Mobile phone with a computer function can be found on the service and maintenance device a software that is well understandable and easy-to-use graphical user interface features, and which allows to save configuration records and again to configure any number of gate controls can be used again and again.
