Abstract
The utility model discloses an interface circuit of a multifunctional intelligent access management system for certificates. The interface circuit comprises a central processing unit (CPU), an indicator light management circuit and a serial interface, wherein the input of the indicator light management circuit is connected with the control signal output end of the CPU, the output of the indicator light management circuit is connected with controlled indicator lights respectively, and the serial interface is connected with the CPU through a bus. The interface circuit has the advantages that each card intelligent access unit is provided with an independent control panel, the CPU of each control panel controls the indicator lights in the card intelligent access units to complete corresponding operations, the arithmetic speed is high, the structure of the circuit is simple, the cost is low, and the like.
Description
Technical field
The utility model relates to a kind of multifunctional certificate intellectual access management system interface circuit.
Background technology
Along with stopping using gradually of a generation ID, increasing people is badly in need of handling two band cermet of identification, and public security department cermet of identification certificates handling center is about to welcome the peak of handling of a Certification of Second Generation.The certificates handling center of certain areas usually needs to manage the thousands of even more cermet of identification of hundreds of, traditional management and to search way be that cermet of identification is divided in the drawer that is placed on file cabinet, the position of being put by staff's manual record certificate, yet, which drawer this position can only be accurate to, specifically want to find this cermet of identification, also needing the staff to go through all over the certificate in the whole drawer just can find, sometimes even need to repeatedly search, the inefficiency of searching, just not saying staff's work capacity is very large, the mode of manual record also is easy to make a mistake, and management is disorderly even may cause certificate to be lost.
Multifunctional certificate intellectual access management system can realize certificate intelligence, fast speed is searched and the failure-free management, has reduced staff's work capacity, simultaneously, has improved efficient and the reliability of certificate management.Yet, management system adopts a plurality of card intellectual access of a main control system house steward unit to reach the draw-in groove indicator lamp that respectively blocks in the intellectual access unit, 9～12 card intellectual access unit are set in each rack, the draw-in groove indicator lamp that arranges in each card intellectual access unit is 100, therefore, the operand of main control system treater is larger, and is higher to the performance requriements of main control system treater.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, provide a kind of and independent control desk is set for each card intellectual access unit, finish corresponding operating, fast operation, the multifunctional certificate intellectual access management system interface circuit that circuit structure is simple, cost is low by the CPU of control desk control indicator lamp.
The purpose of this utility model is achieved through the following technical solutions: multifunctional certificate intellectual access management system interface circuit, it comprises central processor CPU, indicator lamp management circuit and serial interface, the input of indicator lamp management circuit links to each other with the control signal mouth of central processor CPU, the output of indicator lamp management circuit is connected with each controlled indicator lamp respectively, and serial interface is connected with central processor CPU by bus.
Serial interface described in the utility model comprises the RS232 serial interface.
The beneficial effects of the utility model are: for each card intellectual access unit arranges independent control desk, finish corresponding operating by indicator lamp in the CPU control card intellectual access unit of control desk, the characteristics such as have fast operation, circuit structure is simple and cost is low.
Description of drawings
Fig. 1 is the utility model structural representation block diagram.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, multifunctional certificate intellectual access management system interface circuit, it comprises central processor CPU, indicator lamp management circuit and RS232 serial interface, the input of indicator lamp management circuit links to each other with the control signal mouth of central processor CPU, the output of indicator lamp management circuit is connected with each controlled indicator lamp respectively, and the RS232 serial interface is connected with central processor CPU by bus.
Principle of work of the present utility model is as follows: control terminal issues control command to the rack main control system, the rack main control system is by the control desk of serial data line distribution control command to each card intellectual access unit, and the CPU of control desk finishes the operation of specifically lighting or extinguishing by controlled indicator lamp corresponding to each draw-in groove in the indicator lamp management circuit control card intellectual access unit.
