Abstract
The utility model discloses a kind of antistatic entrance guard device, the output end of electrostatic tester is connected with IC integrated chips, IC integrated chips are connected with the relay of workshop electronic gate through relay drive circuit, the electrostatic protector that electrostatic tester is worn to personnel is tested, electrostatic tester test passes, after output high level signal is through the process of IC integrated chips, are changed into the conducting that low level signal controls electronic gate relay, relay conduct electrons gate inhibition opens, and personnel could enter antistatic area.The utility model has the advantages that static electricity on human body's tester is combined with access control equipment, Electrostatic Hidden Troubles are eliminated, save human cost.
Description
Technical field
The utility model is related to a kind of antistatic entrance guard device.
Background technology
When production operation personnel enter electrostatic defending area, the test of electrostatic footwear and electrostatic ring is all with the side of manual oversight
Formula is carried out, artificial check to easily cause does not implement, form on personnel's electrostatic grounding greatly potential leak.This is that the application needs
Where improving again.
Utility model content
Technical problem to be solved in the utility model is to provide for a kind of antistatic gate inhibition for eliminating static discharge hidden danger
Device.
In order to solve above technical problem, the utility model provides a kind of antistatic entrance guard device, electrostatic tester
Output end be connected with IC integrated chips, IC integrated chips connect through the relay of relay drive circuit and workshop electronic gate
Connect, the electrostatic protector that electrostatic tester is worn to operating personnel is tested, electrostatic tester test passes, output high level letter
Number through IC integrated chips process after, be changed into low level signal control electronic gate relay conducting, relay conduct electrons gate inhibition
Open, operating personnel could enter antistatic area.
The model IC 74HC238 of the IC integrated chips.
The relay drive circuit adopts IC TDS62083.
The electrostatic protector refers to the electrostatic footwear and electrostatic ring that operating personnel wears.Electrostatic tester is to operating personnel's
The electrostatic footwear that wears and electrostatic ring are tested, it is to avoid artificial operation.It is qualified after tested that operating personnel wears electrostatic protector,
Electrostatic tester sends test passes signal, that is, send high level signal and deliver to IC integrated chips.It is qualified that IC integrated chips are received
Signal, is changed into low level signal through processing, through the conducting that relay drive circuit controls electronic gate relay, so as to open electronics
Gate inhibition switchs, and allows operating personnel's entrance.
The utility model has the advantages that：
1）Static electricity on human body's tester is combined by the utility model with access control equipment；
2）The utility model is tested using electrostatic tester, it is to avoid human factor；
3）The utility model ensures that operating personnel, when antistatic area is entered, to carry out really the preparation of electrostatic grounding, disappears
Except Electrostatic Hidden Troubles, while also saving human cost.
Description of the drawings
The Figure of description for constituting the part of the application is used for providing further understanding to of the present utility model, this practicality
New schematic description and description is used for explaining the utility model, does not constitute to improper restriction of the present utility model.
In the accompanying drawings：
Fig. 1 is schematic block circuit diagram of the present utility model；

Specific embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Of the present utility model embodiment is described in detail below in conjunction with the accompanying drawings.
Fig. 1 shows that the schematic block circuit diagram of the utility model embodiment, Fig. 2 show the electricity of the utility model embodiment
Lu Tu.As depicted in figs. 1 and 2, the utility model provides a kind of antistatic entrance guard device, the output end of electrostatic tester and IC
74HC23 connects, and IC 74HC23 are connected with the relay of workshop electronic gate through relay drive circuit IC TDS62083,
The electrostatic footwear and electrostatic ring that electrostatic tester is worn to operating personnel is tested.Electrostatic tester test passes, output are high
After level signal is through IC 74HC23 process, it is changed into low level signal, exports to electricity through relay drive circuit IC TDS62083
Cervical orifice of uterus relay, the conducting of control relay, so as to open electronic access switch, allow operating personnel to enter antistatic area.
The utility model is when effectively Inspection personnel enter electrostatic defending area, and electrostatic footwear and electrostatic ring are worn
Qualification, only electrostatic eliminate static discharge hidden danger outside workshop, also save business administration expenditure and manpower into
This.
Preferred embodiments of the present utility model are the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.All of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements that is made etc. are should be included within protection domain of the present utility model.
