Description

The invention relates to a data storage and data transport device for legal nergesteuerte facilities.

There are still many industrial facilities such as CNC-controlled Bearbeitungsmaschi equipment, measuring and monitoring equipment, which are compatible with conventional Data storage devices such as floppy disk drives or tape drives are not enough are allowed. The hardware and software required for this proved to be too high or harsh environmental conditions in some industries such problem solutions useless. Disks have namely the disadvantage that they are sensitive to moisture, heat and magnetic fields. There are also spokes tion and transmission equipment known in which as in the notebook on flash RAM-based memory cards with PCMCIA (pocket card interface adapter) or IDE  (integrated device electronic) are used. However, these problem solutions are very expensive and expensive, especially with regard to the control of the interface.

The invention has for its object an easy-to-use device create, stored with the data and transported to another computer system can be. Furthermore, in particular the operation and the control of the A direction from any standard terminal program from 300 to 57,600 baud at 8 Data bits, 1 stop bit and without parity bit are enabled.

This object is ge according to the invention with the features of claim 1 ge solves. The features of the subclaims make the invention in a distributed manner out.

Thereafter, the electronic device for storing and transporting data and / or programs comprises an electronic device having at least one flash memory memory module and at least one micro-processor or controller. Furthermore, at least one serial interface belongs to the electronic device. The electronic device also has a functionally designed for the data and / or program storage as well as for the data and / or program transport from laid operating system. The entire electronic device is housed in a housing which, according to one embodiment of the invention, is a data storage and data transport connector. According to a further embodiment of the invention, the ge entire electronic device is equipped with a working memory, which is in particular a static RAM chip. After the realization according to the invention is suitable as a serial interface both an asynchronous serial as well as a synchronous serial interface. The asynchronous serial interface is an RS232 or V.24 or RS422 or RS485 interface or TTY current loop interface or an RS232 TTL interface that uses an RS232 transmission protocol and works with TTL levels. The synchronous serial interface is executed in particular as an I ² C-bus interface with a data line and a clock line. According to a further embodiment of the invention is used as an asynchronous interface RS232 or V.24 interface with a standard wired 9-pin or 25-pin Subminiatur- socket or SUB-D socket. According to a preferred embodiment of the invention, the electronic device is provided with an asynchronous interface, which is an RS232 or V.24 interface, as well as with an operating system, via a PC-DOS-based instruction set with instructions for transferring files into the and of the electronic device, equipped with a script interpreter for executing batch programs and a file system for storing files in a flash memory device. The fiction, contemporary device is stationary or mobile use.

This is a simple, flexible to use, programmable device ge in which an operating system based on the DOS instruction set is integrated. This device easily stores data and / or programs and transmits They are just as easy to use in other stores that exist in existing electronic devices gene to execute the process control. The inventive device is therefore in the most concrete device technical embodiment as a plug with memory and To understand transport functions. This will be data and / or programs in existing memory of other machines that do not have ancillary equipment such as floppy disks  own memory, transmit. With the device according to the invention, the Spei other devices, machines and similar Like. Data and / or updated according to the program.

The device according to the invention is in the embodiment with the V.24 interface can be used in particular if the data and / or program update according to ing machines, equipment and Like. With a standard V.24 interface, as each PC, are equipped. In the device according to the invention are first the data and programs needed are stored directly and after making the Interface connection by way of self-activation or by external commands in the existing memory to be updated according to the data and / or program carry.

According to one embodiment of the invention, the memory is a 1 or 2 Mbyte flash Memory memory module used. As a micro-processor or controller is a 16 Bit microcontroller used. A memory of type SRAM, one exclusively Bootstraploader required for internal functions as well as a DC power supply supply complete the embodiment of the invention. The power supply The device according to the invention preferably takes place via pin 13 for 5 V and pin 11 for ground (GND) or 0 V of a subminiature female connector or a 25 pin D-SUB connector or via an extra low-voltage socket for 7-10 V DC. The power supply can thus either via the plug of asynchronous or synchronous serial interface or via an additional connector or via an integrated into the housing of the device according to the invention battery or Ak Cumulatoreinrichtung done.  

The device according to the invention is optionally available with a 1 or 2 MB flash Memory memory module equipped. From this memory area are, for example 64 Kbytes reserved for the operating system of the device according to the invention, while the remaining storage capacity is used to store data and programs. The inventive device is, for example, with a 25-pin socket strip as Interface equipped to the outside.

To transport files in which data or programs are stored is In particular, a terminal program uses the data binary with a simple one ASCII protocol or transported using the ZMODEM protocol. The inventive The device is in the embodiment with a V.24 or RS232 interface easy to control via a standard terminal program with short commands. there be the signals of the device according to the invention in the ratio of 1: 1 or over an adapter connected to a V.24 interface of a computer. Since the invention is equipped with a 25-pin D-SUB socket strip is sufficient it for file transfer, that the inventive device to the serial Interface of the computer or via a corresponding adapter is plugged. It may be necessary to use an extension cable in the ratio 1: 1 or one Adapter with 9-pin D-SUB female connector and 25-pin D-SUB connector to use the.

In general, there are volatile and non-volatile memory. The invention Ein direction has at least one non-volatile memory module. The data and / or  Program transport between the data storage and Data transport device via a serial interface of a computer using a special data transmission protocol. Suitable protocols are, for example binary or ASCII protocols or the ZMODEM protocol.

The commands to be transmitted are entered either directly on the command line or via an existing script file. In the example below this process explains.

After switching on the operating voltage, the script file AUTOEXEC.SCR, automatically activated, which then automatically executes the commands contained therein. To the sem purpose, the inventive device is in particular with the following commands fitted:

The command name determines the command to be executed and must therefore always be attached ben. In addition, at least one parameter must angege certain commands ben. A required parameter may be, in particular, a file name, a da a date, an integer decimal value or a string expression his.
