The production process of copper in China is dominated by copper concentrates and pyrotechnic smelting of blister copper. The status quo is that the processing capacity is greater than the smelting capacity, smelting capacity has greatly exceeded the support capacity of copper concentrate, copper concentrate resources and scrap copper imports are required. Statistics show that in the 21st century, the output of domestic copper concentrate has not been significantly increased, maintaining an annual output of 600,000 tons (copper content, the same below), by the end of 2007 will form nearly 3.7 million tons of smelting capacity, far exceeding By then China's copper concentrate resources and the protection of the capacity of the international market may provide the amount of copper concentrate. The production capacity of copper mines in China can only meet 40% of the smelting capacity.

1. It has the function of mandatory detection and good control, avoiding the accident of personnel or the test of multiple people mixing in one person.
2. The system configuration is flexible and can be flexibly configured according to the budget. The access control can also be reasonably installed according to different situations.
3. Enterprises with strict requirements for ESD can cooperate with smart cards to verify the difference in authority after being authenticated, and assign different permissions to personnel of different identities. For example, an office manager can only pass cards through a channel, and shop floor assembly workers need to swipe their cards. After passing the electrostatic test, it can pass through the channel.
4. The anti-static access control system with RFID function cooperates with the software to display and record all event data in real time; all incoming and outgoing records are transmitted to the computer in real time and can be immediately displayed in the management center computer.
5. The credit card system with high-brightness LCD display function is more humanized; when the test fails, real-time display is card error, time zone error, holiday control and hand and foot errors, in order to remind employees that the test error The content is processed accordingly.
Applicable occasions: SMT production line control area, semiconductor industry clean room, high-tech research and development room, defense and military electrostatic control zone, explosive processing area, aviation space maintenance calibration area, pharmaceutical plant electrostatic control area, hospital control area, biochemical industry Electrostatically controlled areas ... all kinds of situations that require anti-static testing and protection. System functions:
Test authority can be based on hands and feet test need to make a variety of combinations and can be set according to personal clearance level authority (hands, feet, all test, exemption, hand + left foot, hand + right foot, left foot, right Feet (The last four items are temporarily set to allow employees to work in the foot.)
The credit card machine has an LCD display that can display the operation guide language, card number, job number, date and time, test results and alarm information. When the test fails, it can be displayed in real time as card error, time zone error, holiday control, and hand and foot errors reminding employees to know the test error content.
There are various access control functions such as time zone control and holiday control, and flexible access control management.
Follow the steps of swiping the card first and checking the legitimate rights of the card, and then testing the static electricity to avoid illegal card or external card testing.
The ESD test signal can be compared to the wristband and the left and right shoe of the opponent at the same time in order to obtain quick response results. The test procedure should not be preceded by measuring the hand before measuring the foot or measuring the foot first and then measuring the hand to increase the entire test procedure time.
With automatic reset function. After the card is read, the system will automatically reset when the traffic is not available. The transit time can be set and adjusted according to actual needs.
Unattended card recordings, that is, button static tests, can send alarm reminders to remind employees to develop good habits to avoid time-consuming congestion testing.
Different sound and LED indications are provided for both test pass and test pass.
The credit card machine can be applied to medium and large enterprises, each of which can control thousands of people, and credit card data can be stored for more than 10 years.
With anti-destructive micro switch, the alarm signal can be sent when the card reader is damaged.
The built-in access control controls the repeater and opens the door after the system actually compares the test results. This avoids the system fault of sending the door open signal directly by the static tester.

Three-roller factory comprehensive human body electrostatic test data management access control system
Anti-static access control system (human body integrated electrostatic test data management access control system) is an advanced product that combines electrostatic testing with electronic access control systems and computerized management software; in many places equipped with electrostatic protection zones (EPA), electrostatic footwear and electrostatic wrists The test of tapes is conducted by traditional manual login or supervision methods. It is not easy to implement and even implement errors. It is difficult to obtain the trust of customers and management, and it also forms a huge potential hole in personnel's electrostatic grounding. The anti-static access control system targets these. Disadvantages, proposed direct and effective solution to ensure that workers enter the EPA area, do a good job in preparing personnel for electrostatic grounding; and combined with the three roller gate as a control device for human flow channels. It can provide an orderly and civilized way of access for entry and exit, eliminate illegal access, and quickly control the drop in emergencies and organize evacuation. The system is mainly composed of a human body comprehensive tester + access judgment card reader + management software + communication adapter + electronic door lock or access door: 1. Test permission can be made according to the hands and feet test needs 8 combinations and can be set according to personal clearance level Permissions. 2. In addition to the complete set of authority settings, query and alarm functions, the numeric output type can record and manage the actual hand and left and right foot test resistance values. 3. The card reader has an LCD screen to display the operation guide, card number, job number, date and time, test results and error messages. 4. Optional electric locks for access control can be intelligent channel gates such as three-roll gates, swing gates or wing gates, or electronically controlled locks, magnetic locks or building smart locks. Employees can use the exit button or the rotary lock or the reverse lock. Credit card can also be used directly. 5. The software can be optionally added to the attendance management module. The anti-static access control system credit card records can be used for attendance management, class setting, and various attendance reporting functions. The main features of this system:
