Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The present invention designs a method and system for locating candidates' positions based on WIFI and preventing cheating. This method pre-processes the examinee’s information, uses WIFI equipment to scan the earphone APs of each seat, and according to the RSS of each earphone AP (represents the received signal strength, which is the real signal strength. Generally -50dbm--0dbm indicates that the signal is very good) Calculate the seat distance of each earphone (spatial coordinates, each AP has a corresponding spatial three-dimensional area, if it exceeds this area, it will be judged as abn...

Abstract

The invention discloses a method and system for positioning examinee positions to prevent cheating based on wifi. The method comprises the following steps: positioning earphones at all seat points through wifi equipment before examination, and obtaining the position data of earphones before examination; in the examination and in the wireless local area network, scanning the earphone position on each seat through the wireless access point to obtain earphone position data in the examination; comparing the pre-examination earphone position data with the in-examination earphone position data, andjudging whether the examinee replaces the earphone to cheat according to the change of the earphone position data. According to the method and the system provided by the invention, the existing WIFI equipment is used for scanning the earphone AP of the examinee; the earphone position is calculated and positioned according to the RSS of each earphone AP, whether the phenomenon of earphone replacement cheating exists or not is judged according to the earphone position change of an examinee, the earphone dynamic state of the examinee can be monitored in real time, a monitoring blind area does notexist, and an alarm can be given for abnormal change.

Description

technical field [0001] The invention relates to the technical field of intelligent anti-cheating, in particular to a method and system for locating examinees' positions and preventing cheating based on wifi. Background technique [0002] At present, more and more listening tests are completed through special test earphones. Existing special exam earphones cannot detect whether the examinee has exchanged earphones after the examinee’s personal information is bound, so it is easy for examinees to exchange earphones in the examination room to substitute for the exam. Aiming at the current situation of taking the test instead, many solutions have been proposed in the market. For example: before the exam: Candidates use the verification terminal to perform identity verification, and enter the exam room after passing the verification information. Passing the exam: Then monitor whether the examinee has exchanged earphones through video surveillance. Although this type of solutio...
