AI Technical Summary

Technical Problem

The traditional physical anti-tamping solution has high requirements for the matching of the POS machine terminal structure shell and the anti-tamping switch, and the design specifications are low, which can easily lead to the POS machine equipment not working normally.

Method used

A light sensing device for the anti-tamping function of the POS machine terminal is adopted, and the device includes a detection control component, a light emitting component and a light receiving component. There is no need for zero-distance contact between the light emitting component and the light receiving component. By detecting the distance between the light emitter and the light receiver, it is determined whether it exceeds the preset safety distance threshold, thereby triggering the safety detection circuit.

Benefits of technology

It reduces the design tolerance requirements for the structural parts of the POS machine housing, improves production efficiency and assembly convenience, and reduces the requirements for the assembly accuracy of the POS machine housing structure, thereby improving the availability and stability of the POS machine terminal.

Abstract

The utility model discloses a light sensing device for an anti-disassembly function of a POS machine terminal. The light sensing device comprises a detection control assembly, and a light emitting assembly and a light receiving assembly which are oppositely arranged in a non-contact manner during use, the light emitting assembly comprises a light emitter and a physical anti-tamper switch; the light receiving assembly comprises a light receiver and a hole groove; the physical anti-disassembly switch can penetrate through the hole groove to be connected to an anti-disassembly detection circuit outside the light sensing device. The light emitter and the light receiver can be connected to a safety detection circuit outside the light sensing device; the detection control assembly is used for detecting the distance between the light emitter and the light receiver, judging the size relation between the distance and a preset safety distance threshold value, and triggering the safety detection circuit when the distance is larger than the preset safety distance threshold value. According to the light sensing structure for the POS terminal tamper function, the light emitting assembly and the light receiving assembly do not need to be in zero-distance contact like two physical tamper switches in a traditional physical tamper scheme, and therefore the design tolerance requirement for structural parts is lowered.
