DE2724065A1 - Data input to processing unit - avoids switch or plug connections and uses serial selection of displayed data - Google Patents

Abstract

The method for inputting data to a data processor is designed to enable unitary construction of the unit irrespective of the data being fed in and to eliminate plug or switch contacts from the current paths. All the input data is read from store and serially displayed. With the aid of the display data can be selected at the appropriate time and then placed in store or alternatively discarded. The data may be sorted into certain groups and then displayed group by group. A microprocessor system has one memory (2c) for all data and one for the selected data (2d). The first store has an output interface (2e) to the display. A key is operated for selection of displayed data.

Description

Method and device for

Input of information (data) The invention relates to a method and an apparatus for information (data) input into information (Data) processing devices according to the generic term of claim 1.

Information (data) processing devices are assigned an input, have all the necessary information (data) in entered the device will. The term information (data) processing device is very general to understand.

It can be, for example, an electronic computer, in particular a pocket calculator with a keypad, a telephone exchange with the rotary dial as input, a process control / regulation, a ripple control receiver / transmitter act with default commands, etc.

The term "information" or

To see "data". It can be data for telecommunications equipment as well as variables for influencing the function of control processes.

The structure of the input and the assignment between input and device has so far been made in such a way that the input has all means in terms of hardware to from there to be able to enter all information (data). As long as this information (Data) are not entered, the device has no knowledge of it.

For example, the known electronic pocket calculator a keypad on which there are as many keys as there are data to be entered, i.e. digits 0-9, calculation rules, function keys etc. are available.

As a result, the keypad takes up a relatively large area, which is a Downsizing the computer is a disadvantageous hindrance in the way.

For ripple control receivers, to name another area of application, it is necessary to set target commands in the evaluation section, i.e. for comparison with the commands received over the network for the purpose of command decoding can. This input has been made so far - the situation is similar with others Process controls - by changing the plug connections between the evaluation part and the switch end output part or by setting switches, their position is evaluated with the help of an electrical circuit or by plugging in connections in a crossbar distributor (the evaluation is carried out with the help of an electrical Circuit) or by exchanging (plug-in connection) a PROM memory in which the Target commands are stored, or by exchanging (plug-in connection) a printed one Switching with the command pattern (the pattern is read via scanning contacts, the evaluation by means of an electrical circuit). Corresponding arrangements are available on the transmitter side for ripple control systems.

The known methods of decoding or command setting in the evaluation part of ripple control receivers have the disadvantage that it is uniform Devices only exist for a ripple control system or for similar ripple control systems, however not a standard receiver for all known ripple control systems. It also rises material effort in the evaluation part with the number of commands per recipient for some Solutions.

In all cases there are plug or switch contacts in the Power paths the decoding of what happens at the usual current and voltage values over time can become a factor of uncertainty.

Corresponding points of view also apply to the other applications. For example, the pocket calculators are depending on their purpose (business calculator, technical-scientific computers) trained differently in the input field.

Contact problems can accordingly be found in the input section (crossbar distributor) occur from process-controlling devices (machine tools).

The invention is based on the task of entering information (Data) in a device so that it is independent of the data to be entered uniform structure of the device is possible and no plug and switch contacts are necessary in the area of the current paths. The solution to this problem succeeds according to of the invention by the characterizing features of claim 1.

Using a game Ausführungsbei shown in the drawing the invention is explained in more detail, with further developing in the context of this description Features of the invention result.

The figures show: FIG. 1 a general illustration of the interaction between the data input and a data processing device, Figure 2 is a preferred one Embodiment of a sound arrangement for implementing the invention Procedure.

The figure shows in the most general form the interaction of a data input 1 with a data processing device 2. While it is common in the prior art was to specify all data that can be entered in hardware in data input 1, is in the method according to the invention, all of the data that can be entered in the device 2 and when prompted by entering level 1, one after the other to the person entering "offered" via a display device 3 for selection. Is watching the information which is to be entered is displayed, the person entering the data confirms the data entry 1, which is now practically just a button, and the information that has just been offered is "separated out" in the device, in particular stored and entered. The one who typed must therefore respond to a display at the correct time, on which continuously one after the other the data that can be entered are displayed with a suitable frequency.

The data to which the correct time is responded is considered to be entered Dates selected. The connection between devices 1 and 2 therefore does not deliver more like in the known case, the data to be entered, which is in the known Case are set or specified at the data input 1, but this connection only supplies the correct-time response signal from the person entering the data record data offered by the device as data to be entered.

Figure 2 shows an embodiment of a circuit that is used for Implementation of the method according to the invention is suitable with advantage. It is one Key 1 'is provided by the person entering in order to generate the correct time response signal is served. This key acts on a microprocessor via an input interface 2a 2b a. This iroprozconor is assigned a memory 2c, in which the entirety the data that can be entered is stored; since these are fixed values, a so-called ROM memory can be used for this purpose. The microprocessor is a memory 2d is also assigned, in which the current data to be entered in each case get saved. The microprocessor 2b acts once via an output interface 2e on a display 3, and on the other hand, on the remaining part 2f of the device, that processes the input data. All parts 2a to 2f form, as indicated by the dashed line Outline indicated, the device 2 according to Figure 1. The data entry according to 1 is through the key l'in Figure 2 is realized.

The microprocessor reads after being prompted to do so by a start signal has been, one after the other in the memory 2c stored entirety of the data that can be entered and brings them one after the other, visually recognizable by the Display 3 for output. If the operator recognizes data on display 3 that are in the Device part 2f are to be entered, then he presses the key 1 ', whereupon the microprocessor stores the data displayed in each case in the memory 2 d. Therefore, the totality of the data that can be entered is available to the operator via the display 3 has been presented, if the button 1'der is pressed in a timely manner, the Memory 2d the data to be entered, which are now sent via the output interface 2e the device part 2f are delivered.

If you want to see which data to be entered is stored (da these are not visible from the outside), one can see the structure according to FIG organize that when you press key 1 'and if there are stored Data only these data are displayed one after the other. If you react in In this case, the time is correct on the display, then e.g. the information displayed invalid, i.e. it will be deleted. It can be replaced by another value if necessary can also be replaced by the same value.

Depending on whether the input memory is activated when the 1. key is pressed for the first time 2d contains data or not, the program will display the data to be entered Data or the program for selecting the data to be entered is called.

To reduce the display or. Selection time is convenient to dates summarize in groups according to generic terms and first these generic terms display (rough selection), from the selected group then as part of a Fine selection the information to be entered or displayed is selected.

The circuit according to FIG. 2 naturally includes a corresponding one Software, a program that controls the display 3, the traffic with the semiconductor memories Pc and 2d, the processing of the key signal and the operation of the Gern # part 2f pretends. These programs can be used by those skilled in the art, according to the type of operating device part 2f or

the type of inputable data stored in the memory 2c is written will. In this context, it may also refer to some specialist articles in the Section data technology of ETZ B, Volume 28, 1976, pages 496 to 509 pointed out will.

It can be seen from the structure of Figure 2 that the device 2 is independent of specific input data is always designed in the same way and is in the Basically only through the type of input that is stored in the memory 2c Data differentiates, but this has no effect in terms of the device.

There are also no plug or switch contacts in the area of the current paths of the input data required because this is via the memory 2d, which is a semiconductor memory is to be made available to the device part 2f via the microprocessor 2b, in all cases it is a question of fixed connections.

In the following two application examples - considered on the basis of the Figure 2 - are described without the invention being limited thereto.

In the case of an electronic pocket calculator, there is the device part 2f from the usual arithmetic logic circuits of a pocket calculator. Instead of a large-area input part with several keys, there is only one Key 1 'and a display 3 with a small number of digits are provided. The ones to be entered Values or data are in memory 2c, i.e. the digits are stored O - 9, the function signs +, -,:, x, the individual functions such as sine function, e-function etc. These data are processed by the microprocessor according to the display 3 is offered and the operator selects the data using the 1 'key, whereby the displayed value is stored in memory 2d.

It is therefore possible to build a pocket calculator with just one Key 1 'and a display 3, which in the minimum case only has a single digit. The calculators would all look the same and only differ through that values stored in the memory 2c or by the electronic design of the device part 2f, which, however, is not externally visible. For example predominantly in the case of a technical-scientific direction of the computer in the memory 3c the variety of technical functions can be saved in the meantime a commercial one Orientation of the computer in the memory 2c mainly data is stored in this direction.

A ripple control receiver in Come into consideration. These ripple control receivers are in the field of energy supply well known.

They receive commands from a transmitter in the electrical supply network are fed in and, depending on a specific command, execute a Switching action off, e.g.

switch the tariff for storage heating or switch the street lighting on / off and the like. These receivers have an evaluation part in which the Commands on the basis of which the receivers should switch can be set for the purpose of Comparison with the received commands. The target commands must therefore be entered in the evaluation section entered. In relation to FIG. 2, the input data thus represent the commands and the device part 2f is the remaining part of the ripple control receiver including its evaluation part, which from its information in a manner not shown the electrical network and one of them also did not supply it Switching action. The memory 2c contains all the known ripple control systems identifying data, e.g.

Times for start and command pulses, pauses, number of steps, etc.

from which the commands for the respective existing ripple control system be put together. In the ripple control receiver according to the invention thus the setting of the command in the evaluation part of the ripple control receiver the correct time c # cren on display 3, which in the case of the command setting Everyone Programming variables of the ripple control telegram of a certain ripple control system for the purpose Displays the selection of the commands to be entered.

You want it with an already installed or programmed receiver see which commands are set (since these are not visible from the outside), so you can organize the structure of Figure 2 so that in the case already set Commands only the values assigned to them are displayed. reacted In this case, if you click on the display with the correct time, the displayed size will be invalid, i.e. it is no longer used as a criterion for the command. She can get through a different value, if necessary also be replaced by the same value.

The signal triggered by the programmer's reaction causes that the quantities marked in this way are stored in a preferably semiconductor memory 2d, who stores their data in such a way that they cannot be lost, are written in or deleted there will.

All the data (input data) stored in the memory 2d are thereby to recognize and, if necessary, to execute a command while receiving a ripple control transmission used.

The programming of the microprocessor system is made so that the control of the display, the traffic with the semiconductor memory, the processing of the response signal and the control of the output part is done so that all tasks of the evaluation part in a ripple control receiver to be fulfilled. The microprocessor, the memory and the display as well as the button for generating the Response signals are an integral part of the evaluation part of the ripple control receiver, i.e. the device.

It can be seen that with the help of the invention, a uniform structure of the evaluation part is possible for all known ripple control systems, a large number of commands per recipient can be specified and good adaptability of future ripple control systems is available. The receiver according to the invention does not need any additional precautions to adjust the mistake and has none Plug or switch contacts in the area of the current paths for the command settings and decoding.

In Figure 2, two memories 2c and 2d are shown. These two In principle, memories can also form a shared memory. The memory are preferably semiconductor memories, but are not limited thereto. as Memory or memory part 2d, a programmable memory is preferably used, a so-called PROM. Such memories are known to the person skilled in the art today. The ad 3 is preferably an alphanumeric display implemented by known means can be.

The unline of the device 2 according to Figure 2 is not intended to do so understand that it is a closed system; rather can starting from the device part 2 f still lines of action to the outside be present, e.g.

Lines of action that act on a process, or lines of action, to enter information from the outside into the device part.

As already in connection with a ripple control receiver as an application example explained, the programming of the microprocessor system can be done so that the display 3 can also be used to display data that has already been entered can. A part of the program, the deletion of already entered in the memory 2 d Data is also provided.
