Problems solved by technology
However, the existing access control system for personnel cannot meet the actual needs of pharmaceutical companies
This is because the existing access control can only perform the access control switch mechanically, but cannot recognize the number of people in the monitoring area
Secondly, the traditional access control cannot check and judge the cleaning and sterilization status of the equipment worn by the entering and exiting personnel

Embodiment Construction
[0012] According to one or more embodiments, such as figure 1 shown. A personnel access management system in a pharmaceutical production clean area includes a special iris recognizer for the clean area. The iris recognizer comes with an Ethernet interface and an independent control unit, which is convenient for users to authorize operations from the network client. The iris recognizer has a Wigand communication interface, and the authorization authentication information and historical records are sent to the subsequent controller through this interface, and then transmitted to the system platform through the controller. The casing of the iris recognizer is made of SUS304 stainless steel, and the iris collection area is made of PMMA (plexiglass) material.
[0013] The personnel access management system also includes an access controller with Wiegand interface. The access controller includes a core micro-processing unit, Ethernet communication interface, RS485 / 232 communicatio...

A pharmaceutical production clean area personnel access management system comprises an access control machine, the access control machine is used for controlling personnel access in a pharmaceutical production clean area, the access control machine is provided with an iris recognizer, and the iris recognizer identifies identities of personnel entering and exiting the pharmaceutical production clean area through recognition of human body irises and sends the identities of the personnel entering and exiting the pharmaceutical production clean area to the access control machine. When a person entering and exiting a pharmaceutical production clean area wears the protective eyeshade on the head, a human body iris image acquired by the iris recognizer is influenced by the protective eyeshade to generate a reflection light spot, and the iris recognizer processes the iris image by adopting a strong light inhibition algorithm, a wide dynamic processing algorithm and / or a backlight compensation algorithm.
Description
technical field [0001] The invention belongs to the technical field of pharmaceutical production, and in particular relates to a personnel access management system in a clean area of pharmaceutical production. Background technique [0002] Due to the particularity of the production environment of pharmaceutical companies, the staff in the clean area of the production workshop must wear clean clothes, masks, protective goggles, gloves and other special wearable equipment and cannot wear jewelry. Not only that, the clean area should be regularly disinfected, and the disinfection method is chemical reagent fumigation or ozone disinfection, which is easy to produce chemical reactions on the equipment, resulting in safety risks to the clean area. [0003] Therefore, in the production workshop of pharmaceutical companies, the control of personnel access and quantity control are necessary requirements. However, the existing access control system for personnel cannot meet the a...
