Description

Technical Field

[0001] The invention relates to the technical field of workshop safety detection, and in particular to an access control system for an explosive production workshop. Background Art

[0002] In gas stations, industrial and mining enterprises, oil fields, refineries, liquefied gas stations and other units, static electricity is a serious hazard. The static voltage is often as high as several thousand volts or even tens of thousands of volts. When static electricity causes spark discharge, it may also cause fire and explosion. For explosives manufacturers, the existence of high-voltage static electricity and the radio frequency generated by mobile phones also have the risk of detonating explosives. The common way to generate static electricity is friction. The better the insulation of the material, the easier it is to generate static electricity. Usually, pure cotton clothing can reduce the generation of static electricity. Therefore, most work clothes are made of pure cotton, and the dress code is not guaranteed. At present, workshops or construction sites usually need to check whether the personnel entering the workshop are dressed in standard clothes and whether they carry prohibited items. The current static electricity detection equipment can realize the functions of static electricity detection and static electricity elimination, but it cannot realize whether the dress meets the requirements, and it does not detect whether the prohibited items are carried. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides an access control system for an explosive production workshop, which can detect and eliminate static electricity on personnel, and detect whether personnel are carrying electronic products.

[0004] The present invention provides an access control system for an explosive production workshop, comprising a first door (1), a second door (2), a third door (3), and a fourth door (4); an insulating platform (6) is symmetrically arranged inside the first door (1), a static electricity detection device A (7) is arranged inside the insulating platform (6), and a static electricity elimination device (8) is arranged behind the insulating platform (6); the second door (2) is an isolation door, and a workshop simulation area (9) is arranged between the second door (2) and the third door (3); the third door (3) is also provided with an insulating platform (6), and a static electricity detection device B (11) and a mobile phone detection device (12) are arranged inside the insulating platform (6); and a door control lock (5) is arranged on the fourth door (4).

[0005] The access control system further includes a processor, a data transmission unit, an analysis unit, a display unit, a storage unit, a control unit and an alarm unit;

[0006] The electrostatic detection device B (11) and the mobile phone detection device (12) of the third door are connected to the analysis unit via the data transmission unit, the output end of the analysis unit is connected to the input end of the processor, the input end of the display unit, the input end of the storage unit, the input end of the control unit and the input end of the alarm unit are all connected to the output end of the processor; the access lock (5) is connected to the output end of the control unit, and the electrostatic detection device A (7) and the electrostatic elimination device (8) of the first door (1) are connected to the input end of the storage unit.

[0007] The data detected by the electrostatic detection device B (11) and the mobile phone detection device (12) of the third door (3) are transmitted to the analysis unit through the data transmission unit. The analysis unit analyzes the status of the person entering the third door (3) based on the received data, and transmits the analysis result to the processor. The processor determines whether the door opening condition is met based on the pre-set electrostatic threshold and judgment condition. If the electrostatic value carried by the person entering the third door (3) is less than the electrostatic threshold and the person does not carry a mobile phone, the processor sends a signal to the control unit, and the control unit allows the access lock (5) to be opened. If the person swipes the card, the access lock (5) will be opened. If the electrostatic value detected by the person entering the third door (3) is greater than or equal to the electrostatic threshold or the person carries a mobile phone, the processor sends a signal to the control unit, and the control unit prohibits the access lock (5) from being opened. If the person swipes the card, the access lock (5) will not be opened. At the same time, the alarm unit sends an alarm to indicate the cause of the error.

[0008] The processor transmits the electrostatic data to the storage unit for storage and to the display unit for display.

[0009] A temperature and humidity control system (10) is also provided in the workshop simulation area (9), comprising a temperature and humidity detection device and a temperature and humidity adjustment device. The temperature and humidity control system (10) is connected to the temperature and humidity recorder of the workshop. The temperature and humidity control system (10) adjusts the temperature and humidity of the workshop simulation area (9) according to the temperature and humidity of the workshop so as to keep it consistent with the temperature and humidity of the workshop.

[0010] The length of the workshop simulation area (9) is 10-15 meters. When a person passes through the first door (1), the static electricity detection device A (7) of the first door (1) first collects static electricity data on the person, and then the static electricity elimination device (8) eliminates the static electricity on the person. Then the person passes through the second door (2) to enter the workshop simulation area (9). When the person passes through the workshop simulation area (9) and the third door (3), the static electricity detection device B (11) and the mobile phone detection device (12) detect the static electricity on the person and the items carried by the person. If the conditions are met, the fourth door (4) is opened. If the conditions are not met, the fourth door (4) is not opened, and an alarm is issued to indicate the cause of the error.

[0011] After the static electricity is eliminated at the first door, the static electricity exceeds the threshold at the third door, which means that the employee's clothing does not meet the requirements and is made of materials that are prone to static electricity and are not suitable for use in the workshop.

[0012] The beneficial effects of the present invention are that static electricity on people entering a workshop can be detected and eliminated. By setting up a workshop simulation area, it can be judged whether the employees are dressed in standard attire, thereby avoiding the generation of high static electricity after people whose attire does not meet the requirements enter the workshop. At the same time, it is detected whether the people carry mobile phones and similar items, thereby reducing the explosion risk factor of the workshop and ensuring production safety.
