Definitions

  • the invention relates to a method for data exchange between an electrical device and a user interface via a data network.
  • Known electrical devices in particular electrical household appliances, usually have an electronic microprocessor control in which signals from sensors are evaluated and from which certain actions are triggered depending on user inputs and on the received sensor signals, for example by actuating actuators.
  • a central computing and control unit processes both the user inputs and the sensor signals and, after a plausibility check, triggers corresponding predetermined actions.
  • remote control and / or remote monitoring of the electrical device may be desirable, which can take place in a near field by means of wireless data transmission, for example by optical means or by means of radio signals. If communication between the user and the electrical device is to take place over greater distances, the data can be transmitted in a suitable manner via a data network, in particular a public data network such as the Internet.
  • the communication data are typically transmitted as smaller data packets, which may take different paths in the data network and are only put together again at the recipient.
  • the order of arrival at the receiver can also differ from the order of transmission, since each data packet contains information relating to an entire, related data record.
  • These data packets transmitted in rapid succession are typically also referred to as objects, each of which comprises at least one piece of control information or status information.
  • objects can be, for example, an operating mode, an oven temperature, an operating time and a switch-off time.
  • Multiple objects are typically required to control the entire device. Due to the control logic stored in the central control unit, a certain sequence of calling the objects must be followed become.
  • US-A-58 83 801 a device and a method for controlling a microwave oven are known in which user inputs are coded in such a way that a microprocessor control can be controlled with them and that the inputs can be checked for plausibility.
  • US-B-61 98 975 further describes a method for data coding and a data architecture for controlling the parameters of a physico-chemical or a thermodynamic process. Such a process can in particular be the operation of a microwave oven.
  • An object of the present invention is to provide a reliable method for remote control and / or monitoring of an electrical device.
  • this object is achieved in a method according to the preamble of claim 1 in that with each data packet a complete data set with all the control information that can be used to control the electrical device is transmitted from a user interface.
  • the data record can also contain excess information, which in this case is given a neutral status. In this case, for example, a "zero" or a specific targets defined value, eg OxFF or the like, to be contained in the data packet. In this way it is clearly defined that the setting of this parameter is not desired, but the setting or status of the relevant parameter should remain unchanged.
  • certain objects that belong together are grouped together in so-called collectibles.
  • the accesses can be made either via a single data object or alternatively via the individual objects, since the order of transmission is not critical here.
  • the combined objects are preferably also used and transmitted here, since this reduces the volume of data on the transmission medium.
  • the method according to the invention enables a shortening of the reaction time of the overall system.
  • the method according to the invention is particularly suitable for remote control and / or remote monitoring of an electrical household appliance, for example a cooking appliance or the like.
  • remote control and / or monitoring can be carried out over long distances via a private or public data network, in particular the Internet ,
  • a user interface can be an operating unit that is coupled to the data network, for example by establishing a modem connection to the Internet.
  • the user interface can also be a specific program with a user interface that is easy and clear for a user to use.
  • This program can, for example, be stored on a specific computer that can connect to the data network.
  • the program can optionally also be stored on the Internet, so that a program call and thus remote control and / or monitoring is possible with any computer that is connected to the Internet.
  • the user interface can also include a program for speech recognition, so that by dialing a specific telephone number, a speech controlled communication over the data network can be started with the electrical device.
  • the data packets referred to as collector objects can preferably only be used to transmit control information that cannot trigger critical situations in the device. For security reasons, the plausibility of the information contained in the data packets is preferably checked. It can also be useful if safe operation is monitored at all times in the electrical device, for example by evaluating the signals supplied by temperature sensors, by defining maximum temperatures or other maximum values, or by a safety shutdown after a certain period of time has been exceeded.
  • FIG. 1 shows a block diagram of an electrical device which can be operated using a method according to the invention
  • Figure 2 is a schematic representation of an exemplary communication process in the inventive method.
  • FIG. 1 shows a schematic block diagram of an electrical appliance 2, which can in particular be an electrical domestic appliance such as a cooking appliance or the like.
  • this has a central computing and control unit 4, which can process the output signals of a number of sensors 6.
  • a sensor 6 can be, for example, a temperature sensor in a cooking appliance or a flow sensor in a dishwasher or the like.
  • a number of actuators 8 are controlled by the central computer and control unit 4.
  • an actuator 8 is to be understood as any electrically controllable component and / or control element that influences or represents a function in the electrical device 2.
  • Such an actuator 8 can For example, a cooking surface of an electric cooking device, a water pump or an electric heating element in a washing machine.
  • the central computing and control unit 4 is moreover preferably provided with at least one first control panel 12, which serves as a user interface and transmits the inputs made by a user to the central computing and control unit 4.
  • This first control panel 12 can comprise, for example, a plurality of pushbuttons or rotary switches or keys, by means of which various functions or programs on the electrical device 2 can be selected or influenced.
  • the display field 10 can be designed, for example, as a numerical display, as a bar display or the like.
  • the electrical device 2 further comprises a communication interface 14, which is coupled to the central computing and control unit 4 via a detachable line connection 16 and via which a connection to a data network 18 can be established.
  • the data network 18 can be any computer network, for example a LAN, a WAN or the Internet.
  • FIG. 1 further shows a user interface 20, which also has a detachable line connection 16 to the data network 18.
  • the user interface 20 can in principle be designed as hardware or software, which enable user input to the electrical device 2 and / or user and status queries from the device 2.
  • the user interface 20 can be designed, for example, as a remote control that has a second display field 22 and a second control field 24.
  • these second display and control panels 22 and 24 can also be simulated by a program and displayed on a screen.
  • An advantageous embodiment of the user interface 20 can also consist, for example, in a speech recognition program which enables voice-controlled input and query from any communication terminal placed in any way. In this way, the user does not need any operating device, software or hardware to control the electrical device 2 or to query its status.
  • An essential aspect of the invention consists in that only complete data packets are transmitted via the data network 18, which are referred to in the present context as collection objects 305 (cf. FIG. 2) and all parameters that are suitable for operating the electrical device 2 or operating commands le 30 - hereinafter referred to as objects 301, 302, 303 - contain.
  • three different inputs are made by the user interface 20, ie a first, a second and a third object 301, 302, 303 are generated.
  • the first object 301 can be, for example, the selection of a cooking surface.
  • the second object 302 can then, for example, characterize the degree of heating or the temperature for this cooking surface.
  • the third object 303 can, for example, characterize a time period over which the degree of heating is maintained.
  • the three selected objects are then combined to collect object 305 and transmitted to the electrical device 2 as a single data packet via the data network 18.
  • the method according to the invention ensures that the correct sequence of the control information sent is maintained at all times by the central computing and control unit 4, even if the data are transmitted, for example, via the Internet, where data packets belonging together may take a different transmission path and often - sometimes have different transmission times.
  • status information can also be transmitted from the device 2 to the user interface 20, namely as collection objects 305, each of which contains and transmits all the status parameters in question.
  • Information that is not required is identified in the same way with a neutral parameter or with "zero".
  • a safety function of the method according to the invention consists in that only limited influence on the device functions is possible via the communication interface 20. If, for example, an automatic safety shutdown is initiated after a certain timeout, then this time limit value can preferably not be influenced remotely.
  • a safety shutdown can also be initiated in the case of a cooking appliance if the temperature is exceeded. Here, too, it makes sense if a restart is not possible from a distance, but only a maintenance service can be contacted.
