Description of drawings
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is an application system connection layout of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described.
A kind of Intelligent key and file administration cabinet control circuit, as shown in Figure 1, comprise master controller, switching input module, electronic lock state output module, switching value output module, electronic lock state load module and electronic lock, master controller is connected with switching input module, electronic lock state output module, switching value output module and electronic lock state load module respectively by the I/O interface, the switching value output module is connected with the input end of electronic lock, and the output terminal of electronic lock is connected with electronic lock state load module.In the present embodiment, that described master controller adopts is the technical grade microcontroller AT89C52 that Atmel company produces, and this controling appliance has characteristics such as stable performance, aboundresources, low-power consumption; Described switching input module, electronic lock state output module mainly are made of the RS485 communication module and are connected with control center, the switching value information that this circuit mainly sends control center sends master controller to, can send the state of each electronic lock in the current file administration cabinet to host computer simultaneously; Described switching value output module is is mainly connected and composed by serial parallel conversion chip 6B595 and chip for driving 74HC2803, realizes the drive controlling function to electronic lock; Described electronic lock state load module mainly is made of the 74HC373 latch, and it is connected with nine I/O mouths of master controller and can expands, and electronic lock state load module can be preserved the state of electronic lock up to master controller and read its state.
In the present embodiment, in order to realize the function of large batch of key and file administration, the needs that need the expansion of switch amount output module, therefore the switching value output module has adopted the 6B595 chip of serial input and line output, this 6B595 chip is connected with three I/O interfaces of master controller, no matter expand what switching values output, all only take three I/O mouths of master controller, reached and take the purpose that master controller I/O mouth can be expanded again simultaneously less.Because the driving force of master controller and 6b595 chip is not strong, its each pin output current only is 10mA, in order to make the switching value output module drive the bigger device of electronic lock constant power, so added chip for driving 74HC2803 in the back of 6b595 chip, the driving force of this chip for driving can satisfy the demand of driving than high power device much larger than master controller and 6b595 chip.
As shown in Figure 2, the file administration cabinet that this control circuit is installed can constitute an Intelligent key and file administration cabinet control system with control center and hand-held laser scanner, hand-held laser scanner is connected with control center, and control center is connected by the RS485 mode with Intelligent key and file administration cabinet.Control center can carry out data acquisition, analyzing and processing to coupled hand-held laser scanning terminal etc., control center communicates by RS485 communication mode and Intelligent key and file administration cabinet, control circuit by Intelligent key and file administration cabinet is controlled in real time to electronic lock, the status information of electronic lock is given control center by the loopback of RS485 communication mode, realizes the real-time monitoring and control to electronic lock.Key and archives distribution managerial demand and operation note security control digital quantity output needs have in batches been satisfied.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
