Abstract

The invention relates to a method for coding mailing items by means of applied readable code signs. In order to enable also umambiguous identification of short mailing items while maintaining code sign quantity and distances, the surface available for code application, especially the length of the incoming mailing item, is measured and an unambiguous code with a number of signs adapted accordingly to the surface available is subsequently applied. In order to check that an identification code (ID code) is umambiguous a statistic is provided with regard to the frequency of various lengths of previously processed mailing item available for the ID code affecting the number of signs in the ID code. ID codes with a reduced number of signs, each of which have been determined and adapted to the lengths available for the ID code are applied when, over a fixed period of time, the number of statistically determined mailing items of the selected length range is smaller or equal to the number of mailing items which can be distinguished by the shortened ID-code.

Printing and reading technology should be as simple and cheap as possible, and reading reliability as high as possible
Verwendung von Balkencodes ist heute die einfachste und dabei relativ sichereUsing bar codes is the simplest and relatively secure today
Methode der einzeilige Druck eines fluoreszierenden Bar/No-Bar-Codes mit einem Balkenabstand von z B 1 ,5 mmMethod of single-line printing of a fluorescent bar / no-bar code with a bar spacing of e.g. 1.5 mm
Die Kodierung und die Zeichenanzahl und -abstände werden bisher so festgelegt, daß für die häufigsten Sendungen mit größerer Standardgroße die Kodierungen, insbes Identifikationskodierungen, eindeutig sind und den dafür vorhandenen Platz möglichst ausfüllenThe coding and the number and spacing of characters have so far been determined in such a way that the codes, in particular identification codes, for the most common items with a larger standard size are clear and fill the space available for them as far as possible
Befinden sich unter den Sendungen auch Sendungen mit geringerer Lange als dieAre there also consignments of shorter length than the consignments?

Lese- und Drucktechnik sowie eine Verminderung der Lesesicherheit zur Folge haben Der im Anspruch 1 angegebenen Erfindung liegt deshalb das Problem zugrunde, Sendungen mit unterschiedlicher Große unter Beibehaltung der für große Sendungen gewählten Kodezeichengroße und -abstände eindeutig zu kodierenReading and printing technology as well as a reduction in reading security The invention specified in claim 1 is therefore based on the problem of uniquely encoding mail items with different sizes while maintaining the code character size and spacing selected for large mail items
Durch die Ermittlung der zum Aufbringen des Kodes zur Verfugung stehenden Flache der eingehenden Sendungen und durch die Wahl und anschließendes Aufbringen eines eindeutigen Kodes mit einer der jeweils ermittelten Flache für die Kodierung angepaßten Zeichenanzahl ist es möglich, trotz kleinerer Sendungen die ursprüngliche Zeichengroße und Zeichenabstande beizubehalten Zum Ermitteln der für die Kodierung zur Verfugung stehenden Große sind verschiedene Verfahren möglich So wird beim optischen Abtasten der Sendungsoberflache am vereinbarten Ort der unbedruckte Bereich und dessen Große ermittelt In vielen Fallen reicht es, die Lange zu ermitteln, oder es wird einfach die Sendungslange gemessen und um einen festen Betrag reduziert Gemäß Anspruch 2 ist es vorteilhaft, zur Reduzierung der Stellenanzahl eines ID- Kodes vorhandene Redundanzinformationen zu reduzieren Bei einem ID-Kode kann gemäß Anspruch 3 bei kleineren, insbesondere kürzeren Sendungen und deshalb reduzierter Zeichenanzahl die Eindeutigkeit des ID-Kodes überprüft werden, indem über die Häufigkeit unterschiedlicher, für den ID-Kode zur Verfugung stehender Langen bisher verarbeiteter Sendungen, die Auswirkungen auf die aufzubringende Zeichenanzahl haben, eine Statistik gefuhrt wird Die Eindeutigkeit ist gegeben, wenn für den betrachteten Zeitraum mit der der Lange angepaßten ID-Kode-Anzahl alle angefallenen Sendungen eindeutig unterscheidbar sindBy determining the area of the incoming mail items available to apply the code and by selecting and then applying a unique code with a number of characters adapted to the respective determined area for the coding, it is possible to maintain the original character size and character spacing despite smaller items Various methods are possible to determine the size available for coding. For example, when scanning the surface of the item at the agreed location, the unprinted area and its size are determined. In many cases, it is sufficient to determine the length, or simply measure the length of the item and around a fixed amount reduced According to claim 2, it is advantageous to reduce existing redundancy information to reduce the number of digits in an ID code number of times, the uniqueness of the ID code is checked by making a statistic about the frequency of different lengths of previously processed items available for the ID code, which have an impact on the number of characters to be applied. The uniqueness is given, if for the one under consideration Period of time with which the number of ID codes adjusted to the length can be clearly differentiated
Nachfolgend wird die Erfindung an Ausfuhrungsbeispielen erläutertThe invention is explained below using exemplary embodiments
Beispiel 1 zur Kürzung von ID-KodesExample 1 for shortening ID codes
Als eindeutiges Sendungskennzeichen soll eine 10-Stellιge Dezimalzahl im Klartext aufgedruckt werden, um taglich 100 Mio Sendungen über einen Zeitraum von 100A 10-digit decimal number in plain text is to be printed as a clear consignment identifier, to correspond to 100 million consignments per day over a period of 100
Tagen eindeutig zu unterscheiden Es ist aufgrund statistischer Erhebungen bekannt, daß 3% der Sendungen zu kurz sind, um 10 Ziffern aufzunehmen, jedoch ausreichend lang um mit 9 Ziffern bedruckt zu werdenDistinguishing days clearly It is known from statistical surveys that 3% of the items are too short to contain 10 digits, but long enough to be printed with 9 digits
Der Vorrat von 1010 unterscheidbaren Zeichenfolgen beinhaltet nicht nur 10-stellιgeThe supply of 10 10 distinguishable strings does not only contain 10 characters
Zahlen, sondern auch kürzere, nämlichNumbers, but also shorter ones, namely
109 neunstellige10 9 nine-digit
+108 achtstellige+10 8 eight-digit
++
Zeichenfolgen (eine fuhrende Null muß im Zehnersystem nicht gedruckt werden) Damit können bis zu 11 ,1 % der Sendungen mit kürzeren als 10-stellιgen Kennzeichen versehen werden Dieser Anteil ist großer als 3%, das heißt alle auftretenden Sendungen können ohne Verlust der Eindeutigkeit und ohne sonstige Nachteile eindeutig gekennzeichnet werdenStrings (a leading zero does not have to be printed in the tens system) This means that up to 11.1% of the items can be provided with labels shorter than 10 digits. This percentage is greater than 3%, which means that all items can be clearly identified without loss of uniqueness and without other disadvantages
Beispiel 2 zur Kürzung von ID-KodesExample 2 for shortening ID codes
Die zu druckende Information sei in Bar/No-Bar-Technik zu drucken und bestehe aus 40 Bit Ziehnformation und 40 Bit ID-CodeThe information to be printed is to be printed in bar / no-bar technology and consists of 40-bit drawing information and 40-bit ID code
Mit der Vereinbarung, daß ein gedruckter Balken eine binare „Eins" und ein ausgelassener Balken eine binare „Null" bedeuten, enthalt der verfugbare Vorrat vonWith the agreement that a printed bar means a binary "one" and an omitted bar means a binary "zero", the available stock contains
240 Zeichenfolgen2 40 strings
239 Folgen der Lange 39 Balken,2 39 episodes of the Lange 39 bars,
238 Folgen der Lange 38 Balken, usw2 38 sequences of length 38 bars, etc
Können auf kurze Sendungen z B nur 75 anstatt 80 Balken aufgebracht werden, so stehen immer noch mehr als 3% der Zeichenfolgen (235/240 = 0,031 ) für diese Falle zur VerfugungCan in the short program eg only 75 instead of 80 bar applied so are still more than 3% of the strings (2 35/2 40 = 0.031 ) for this case at your disposal
Beispiel 3 zur Kürzung beliebiger Kodes versehen mit RedundanzExample 3 for shortening any code provided with redundancy
Zur Fehlerminderung werden der zu druckenden Information Redundanzzeichen hinzugefugt Dabei stehen wahlweise drei Verfahren zur Verfugung Die Gesamtmenge der druckbaren Zeichenfolgen setzt sich also aus drei Teilmengen von Zeichenfolgen unterschiedlicher Lange zusammen Abhangig von der gemessenen Sendungslange wird eine Zeichenfolge aus derjenigen Teilmenge gewählt, die auf dem zur Verfugung stehenden Raum gerade noch druckbar istTo reduce errors, redundancy characters are added to the information to be printed.There are three methods available.The total amount of printable character strings is made up of three subsets of character strings of different lengths. Depending on the measured mail item length, a character string is selected from the subset available on the standing space is just printable
Beispiel 4 zur Kürzung durch verschiedene Arten der KodierungExample 4 for truncation through different types of coding
Üblicherweise soll der aufzubringende Kode eine als Dezimalzahl vorliegende Information repräsentieren Gunstig ist es, wenn der Kode mit Hilfe einer kleinen Schablone vom Menschen leicht entzifferbar ist Bei Verwendung von Bar-No-Bar- Technik bietet sich dazu an, jede Stelle der Dezimalzahl durch eine Gruppe von 4 Balken darzustellen, die dann mit einer 10-zeιlιgen Tabelle leicht entschlusselbar ist Bei Verwendung von 4-state-Balkentechnιk kann jede Dezimalstelle durch zwei Balken repräsentiert werden Eine 3stellιge Dezimaizahl erfordert demnach 3*4=12 Balken in Bar-No-Bar-Technik bzw 3*2=6 Balken in 4-state-Technιk Die Zahl der Balken und somit die erforderliche Drucklange auf der Sendung kann reduziert werden, indem auf Kosten einer für den Menschen leichten Entschlusselbarkeit zu einer binaren Kodierung übergegangen wird In binarer Darstellung genügen 10 Balken in Bar-No-Bar-Technik bzw. 5 Balken in 4-state-Balkentechnik, um jede 3stellige Dezimalzahl darzustellen, denn 210 > 1000 und 4 5 > 1000. Entsprechendes gilt, wenn anstelle von Dezimalzahlen Text kodiert werden soll. Usually, the code to be applied should represent information available as a decimal number. It is advantageous if the code can be easily deciphered by humans using a small template. When using bar-no-bar technology, it is advisable to use a group to place every decimal number of 4 bars, which can then be easily deciphered using a 10-line table. When using 4-state bar technology, each decimal place can be represented by two bars. A 3-digit decimal number therefore requires 3 * 4 = 12 bars in bar-no-bar Technology or 3 * 2 = 6 bars in 4-state technology The number of bars and thus the required print length on the item can be reduced by moving to binary coding at the expense of being easy to decipher for humans. In binary representation, 10 is sufficient Bars in bar-no-bar technology or 5 bars in 4-state bar technology to represent every 3-digit decimal number, because 2 10 > 1000 and 4 5 > 1000. The same applies if text is to be coded instead of decimal numbers.
