Embodiment

[0033] This embodiment detects the software cheating function of the Bawang electronic pricing scale, such as figure 1 As shown, the main body of the present invention, the electronic price calculation scale software cheating detection device includes: the electronic price calculation scale 16 to be detected is placed in the airtight container 11, and the airtight container 11 and the cast iron platform 12 are connected to each other by hexagon socket bolts and nuts 20, which can eliminate external factors The interference caused to the detection device; the illuminating lamp 8 provides the required light source for the machine vision system, thereby ensuring the accuracy of the digital tube character recognition; the power supply 14 is the power supply for the set of devices.

[0034] Before the test, one end of the relay 17 is connected to the button interface of the main board chip 19 of the electronic price calculation scale, and the other end is connected to the host compu...

Abstract

The invention relates to a device and method for testing software cheating of an electronic price computing scale. A programmable-control multi-circuit relay is used in a key simulator in the device for achieving the key function; a calibrator is used in a weighing simulator for simulating the weighing sensor function; the output of a nixie tube is captured, wherein a machine vision system is used for capturing the output of the nixie tube. The machine vision system comprises a hardware interface and a software character recognition algorithm. The simulators and an output capturing device are connected with an Ethernet port and an upper computer through serial ports so as to achieve interaction with an upper computer simulation system, and therefore all the functions of the electronic price computing scale are transferred onto the upper computer. The upper computer simulation system automatically generates a random test case to test the software cheating function and stores a test result. The device and method for testing software cheating of the electronic price computing scale can test the software cheating function of common electronic price computing scales in the current market, the whole test process is finished by the computer simulation system, the automation degree is high, the test efficiency is high, and the test time is short.

Description

technical field [0001] The invention belongs to the field of software simulation testing of embedded measuring instruments, and relates to a software cheating detection device and method for an electronic pricing scale. Background technique [0002] Some unscrupulous merchants in the market use electronic price calculation scales to cheat, so that the goods sold are short of catties. Complaints about cheating on electronic price scales are also increasing. According to the data of the General Administration of Quality Supervision, Inspection and Quarantine in 2012, the quality sampling pass rate of electronic pricing scales is only 63.3%. Cheating on electronic scale hardware is relatively easy to detect, while cheating on software is hidden and difficult to find. Therefore, most of the cheating on electronic price-calculating scales on the market is to modify the software to cheat. [0003] In order to strengthen the supervision and management of electronic price scales, ...
