ESD (electrostatic discharge) entrance guard detection system

Abstract

The invention discloses an ESD (electrostatic discharge) entrance guard detection system which comprises a main control unit, an ESD test host unit, a channel controller, a background management system, a hand ring detector, a shoe detection pedal, a foot ring detector, a gate mechanism, a card reader and a channel sensor arranged in an entrance guard channel, wherein the ESD test unit is connected with the main control unit through an RS485 data wire; the channel controller is connected with the main control unit through an RS232 data wire; the background management system is connected with the main control unit through an Ethernet wire; the gate mechanism and an audible and visual alarm are connected with the signal output end of the channel controller; the hand ring controller, the shoe detection pedal and the foot ring detector are connected with the main control unit through a CAN (Control Area Network) bus; the card reader is connected with the main controller through a Wigan signal wire. The system can perform ESD detection and identity inspection on staff entering an SMT (Surface Mount Technology) workshop through an entrance guard gate machine, so that the electrostatic safety control and intelligent management level of a factory is promoted.

Description

technical field [0001] The invention belongs to the technical field of ESD electrostatic detection, in particular to an ESD access control detection system. Background technique [0002] In SMT factories and enterprises, when production personnel enter the SMT workshop, the tests of static shoes, static anklets, and static wristbands are all carried out through manual supervision. Manual inspections are likely to cause falsehoods, resulting in hidden dangers and loopholes in the static grounding of personnel. . [0003] The patent literature with the Chinese patent application number 201410550518.2 discloses an intelligent anti-static detection device, which can monitor personnel dynamics and site conditions in real time on the basis of the existing anti-static device technology through the intelligent anti-static detection device, and achieve overall The effect of linkage; the device adopts the traditional circuit structure, the function is relatively simple, it can only a...

[0002] In SMT factories and enterprises, when production personnel enter the SMT workshop, the tests of static shoes, static anklets, and static wristbands are all carried out through manual supervision. Manual inspections are likely to cause falsehoods, resulting in hidden dangers and loopholes in the static grounding of personnel.

[0003] The patent literature with the Chinese patent application number 201410550518.2 discloses an intelligent anti-static detection device, which can monitor personnel dynamics and site conditions in real time on the basis of the existing anti-static device technology through the intelligent anti-static detection device, and achieve overall The effect of linkage; the device adopts the traditional circuit structure, the function is relatively simple, it can only achieve the monitoring function, and cannot effectively control the entrance and exit

[0004] Chinese patent application number 201120173427.3 discloses an anti-static alarm, which is used to detect whether the anti-static ability of the static ring is normal by connecting the detection circuit to the static ring, and then through the alarm circuit, the detected The alarm signal is sent out for abnormal situations. However, the alarm only has the function of sound alarm, and cannot intercept the personnel who failed the detection in real time.
