Definitions

  • the invention relates to an industrial truck with a device for acquiring operating data, a data memory in which the operational data can be stored, and an electronic control unit, which controls the detection and storage of the operational data.
  • the invention relates to an industrial truck for remote maintenance.
  • the truck according to the invention has a device for acquiring operating data, a data memory in which the operational data can be stored, and an electronic control unit, which controls the acquisition and storage of the operational data, the truck having a wireless data transmission device, the operating data from Data storage of the truck transmits to an external data storage, wherein the preferably wireless data transmission is initiated by the electronic control unit.
  • the initiation depends on whether the transmission link is available and whether data is to be transmitted. Only if this is the case is a data transmission, eg according to a predetermined program.
  • the external data memory can be queried regardless of whether the vehicle is in operation, in reception range, etc.
  • a "knowledge" database for all data of interest of the vehicle, which are available at any time, regardless of whether a online request is possible at a desired time.
  • the device for acquiring operational data may consist of separate sensors or use the existing on-board sensors. Also possible is the interaction with an existing on-board computer in which operational data are available.
  • the data memory may be, for example, a flash memory which may be integrated in the electronic control unit.
  • the electronic control unit may be, for example, a miniature PC.
  • the truck has a preferably wireless data transmission device, ie a transmitting and receiving unit, with which the operating data are transmitted from the data storage of the truck to an external data storage.
  • a wireless data transmission device ie a transmitting and receiving unit
  • This provides the operational data in the external data memory for further evaluation.
  • the external data memory is independent of the data storage of the truck and allows access to the data stored in it regardless of the current use of the truck. In particular, it is not necessary for there to be, for example, a radio connection or another connection to the data storage of the industrial truck at the time of access to the operating data stored in the external data memory. This greatly facilitates the evaluation of the operational data in practice.
  • the data access also has no effect on the availability of the truck.
  • the wireless data transmission of the operating data to the external data memory is initiated by the electronic control unit.
  • the data transmission is thus automatically triggered by the electronic control unit. No user interaction is required to transfer the data, in particular, neither a service technician needs to connect to the truck's data storage, nor does the truck user need to take special measures to transfer the data. In particular, it does not need to establish a cable connection and remove a memory card or other storage medium from the truck.
  • the initiation of a wireless data transmission may involve the establishment of a radio connection or, in the case of an already existing radio connection, essentially the transmission of the data.
  • the wireless data transmission can be performed by the electronic control unit at predeterminable times or configurable events. The times can be determined, for example, according to the time or by predeterminable time intervals. Such a schedule for data transmission leads to a current database in the external data memory, which allows a timely evaluation of the data. Compared to a continuous data transmission in particular a relief of the radio network is achieved.
  • a data transmission is dependent on whether the transmission path allows a transmission of data, ie the preferably wireless data transmission from the electronic control unit is dependent on the availability eg of a radio connection. It is thus taken into account by the electronic control unit, whether a radio link available and data transmission with the required security is possible. In particular, a data transmission can be omitted if the truck is in an area with poor reception.
  • the electronic control unit checks at predeterminable times whether a radio connection is possible.
  • the initiation of the preferably wireless data transmission from the electronic control unit takes place as a function of the location of the industrial truck.
  • the wireless data transmission can be initiated whenever the truck is located in a specific area of a warehouse or in a depot.
  • a particularly reliable radio connection is possible at these selectable locations.
  • the electronic control unit can initiate a data transmission from the external memory to the storage of the truck. This allows a targeted updating of the program in the internal data memory, i. of the truck.
  • the operational data include data on the driving operation and / or data on the lifting operation and / or data on state variables of the truck and / or data on special events and / or goods-related data and / or personal data. Saving the mentioned data allows a targeted and differentiated analysis of the type and extent of use of the truck.
  • the wireless data transmission device uses a WLAN, GSM, GPRS and / or UMTS network or any other network.
  • a WLAN network When using a WLAN network, a local network can be set up, which enables high data transmission rates.
  • the mobile networks mentioned in particular allow data transmission over long distances.
  • the electronic control device is connected to a vehicle data bus of the truck.
  • the electronic control device can read different operating data of the truck.
  • the vehicle data bus may be a so-called CAN bus (Controller Area Network).
  • the electronic control device, the data storage on the truck and the wireless data transmission device are designed as a retrofittable module.
  • the components mentioned can be accommodated in a common housing.
  • An antenna for the wireless data transmission device may optionally be designed separately and connected to the module.
  • the module can be equipped with suitable connectors for connection to a power supply and for data exchange with the truck. The module enables simple retrofitting of a truck.
  • a remote maintenance system thus comprises, in addition to the already described industrial truck, the further technical infrastructure required for the transmission and central storage of the operational data.
  • this includes at least one data evaluation unit that can access the external data memory.
  • the data evaluation unit can be, for example, a PC, a laptop or notebook, a PDA, a mobile telephone or other manageable device that provides a user interface. With such a data evaluation unit, the operating data stored in the external data memory can be evaluated. By integrating the external data memory into a corresponding network, the data evaluation is possible at any location and at any time.
  • a plurality of industrial trucks is provided which each transmit operational data to the external data memory.
  • the external data storage includes operational data of several trucks, such as a whole fleet of a logistics company. Comprehensive analyzes of the entire fleet, if necessary, can be made via the external data memory.
  • the external data memory is integrated into a computer network of the logistics company that uses the truck.
  • the external data memory can be accessed directly to the external data storage.
  • the external data memory is integrated into a computer network of the company that makes the truck available.
  • This company can be, for example, the manufacturer of industrial trucks or a service company that leases or maintains the industrial trucks. In both cases, the respective company can access the data directly.
  • This makes it possible, for example, to carry out comprehensive technical analyzes for the manufacturer of the industrial truck without adversely affecting the business operations of the industrial truck user. For example, technical innovations of a truck can be analyzed remotely without elaborate tuning work with the truck user.
  • the transmitting and receiving unit in the truck can also cooperate with a buffer for data transmission, which in turn is designed for communication with an external data memory.
  • a buffer for data transmission which in turn is designed for communication with an external data memory.
  • an external data memory For example, it is conceivable that a fleet of industrial trucks, which is used in a company, for example a logistics company, via their transmitting and receiving units with communicate with a company-specific cache. As explained above, this communication is dependent on the availability of the transmission link between the individual vehicles in relation to the buffer.
  • the intermediate memory then in turn communicates with a central data memory at another location, wherein this communication may include its own transmission link, for example a radio link or a wired transmission link.
  • the latches may initiate the transfer to the external main memory.
  • the main memory can query the cache or a large number of buffers in different companies, each having a cache, which in turn communicates with the associated fleet.
  • the buffer may be provided in a battery charging station, which communicates with a memory on a battery, which is positioned for charging purposes in the battery charging station.
  • the operating data which are determined in the truck, transferred to the memory on the battery, which memory in turn communicates with the cache in the battery charging station.
  • This combination preferably takes place via a radio link.
  • the buffer next to the battery charging station can in turn communicate with a main memory at another location, for example via a radio link.
  • the invention is used in particular for the remote maintenance of one or more industrial trucks.
  • remote maintenance is not limited to maintenance work in the narrower sense, but describes all data surveys that can be carried out remotely, ie without direct access to the truck. Thus is not only the condition control of the truck with the aid of the operational data, but also any other analysis and evaluation of this data a remote maintenance in the sense of this application.
  • the user of the data evaluation unit can selectively collect data required for a particular task by creating a corresponding job, e.g. is given to the external memory via the data evaluation unit.
  • the electronic control unit of the truck then collects the desired data in a targeted manner and stores it in the truck's data memory. Subsequently, the data are transmitted to the external data memory as already explained and are thus available for evaluation, in particular by the user of the data evaluation unit who has created the order.
  • the method thus allows targeted data collection with little effort. This is particularly helpful for diagnosing faults and testing new functionalities of a truck if standard data does not provide sufficient information. In this case, specifically more specific data can be collected.
