[0004] However, in practice, it is also found that there are other cases of ETC data retention. The cross-shift retention of ETC data means that there is data retention in the ETC transaction data between two adjacent shifts corresponding to the same PSAM card.

Embodiment 1

[0058] Such as figure 1 and figure 2 As shown, the present embodiment provides a method for analyzing ETC transaction data retention, including the following steps:

[0059] S1: Obtain each hash node in the hash table, the hash node stores the charging point information and the transaction data of each PSAM card of the charging point in each work shift, and the transaction data includes the largest terminal transaction sequence number and The minimum terminal transaction serial number; in this step, the basic data that needs to be analyzed is mainly obtained, but before this step, the data stored at the server needs to be migrated to the hash table, that is, the main data in this embodiment The hash table is designed to store and query data. There are many construction methods of the hash table. The commonly used methods include direct addressing method, digital analysis method, square method, folding method, divisor remainder method and random number method. Among them, th...

Embodiment 2

[0097] Embodiment 2 discloses an electronic device, which includes a processor, a memory, and a program, wherein one or more processors and memories can be used, and the program is stored in the memory and configured to be executed by the processor, When the processor executes the program, a method for analyzing retention of ETC transaction data in Embodiment 1 is implemented. The electronic device may be a series of electronic devices such as a mobile phone, a computer, and a tablet computer.

Embodiment 3

[0099] Embodiment 3 discloses a computer-readable storage medium, which is used to store a program, and when the program is executed by a processor, a method for analyzing ETC transaction data retention in Embodiment 1 is implemented.

Abstract

The invention discloses an ETC transaction data retention analysis method. The method comprises the following steps: obtaining each hash node in a hash table; judging whether the charging point information in the corresponding hash node is empty or not, and if not, executing a PSAM card judgment step; acquiring a PSAM card corresponding to the toll point information, judging whether data at the corresponding PSAM card is empty or not, if so, executing a quantity judgment step, and if not, calculating that transaction data of all work classes of the PSAM card is retained across the work classes. According to the ETC transaction data retention analysis method, storage and extraction of transaction data are completed by setting a hash table, and judgment is performed on data in all hash nodesto obtain transaction data of all work classes for cross-work-class retention; the comparison efficiency is greatly improved, the accuracy of cost settlement is improved, and the cost expenditure ofa settlement unit is reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for analyzing retention of ETC transaction data. Background technique [0002] At present, there are usually two methods for the analysis and mining of expressway ETC data retention. One is to use data mining algorithms to determine the rule base of ETC data retention, and then make predictions based on the ETC data retention rule base. [0003] The other is based on the principle that "each PSAM card used in the ETC lane corresponds to the terminal transaction serial number in the ETC charging record generated in theory is continuous", and the charging record for each PSAM card during each work shift date The terminal serial number in , calculate the span SPAN of the terminal serial number psam =Max 终端机交易序列号 -Min 终端机交易序列号 +1, compare the result with the number of charging records RecNum of the PSAM card on the shift date, theoretically SPA...
