Description
Technical field
The utility model relates to the electric queuing technical field, relates to Zero queuing machine system, especially a kind of Zero queuing machine system with touch-screen evaluating apparatus.
Background technology
Zero queuing machine system is the new high-tech product of a kind of integrated use computer technology, network technology, multimedia technology, Communication Control technology; Can replace the client to rank effectively; Be applicable to all kinds of window services industries, be widely used in industries such as bank, hospital at present.Use the number calling machine system; Can eliminate on the one hand client's long-time " standing in line " arduous, to the complaint of " the wrong team of standing ", " jumping the queue "; Improve service quality and corporate image comprehensively; More can adjust traffic assignments on the other hand, exploit potentialities, rationally arrange window services, reduce the masses' waiting time, increase work efficiency according to statistics.Along with the increasing requirement of client to service quality; The Zero queuing machine system of prior art can use the external cover touch-screen evaluating apparatus of Universal USB peripheral hardware usually;, after the service of receiving, offer the customer evaluation interface and then collect client's evaluation information in order to the client.
But in use; Can run into the behavior that the client touches evaluating apparatus arbitrarily; Its touch action and evaluation behavior are irrelevant fully; This situation will seriously be disturbed normal equipment operation, be necessary to manage touching evaluating apparatus, forbid or the management of shut-down operation for the touch behavior of non-evaluation.In the legacy equipment management method, generally use Hook Technique or call producer the equipment second development interface that provides that used equipment is carried out bookkeeping.Such method is nothing but to have increased difficulty for the developer, and developer's technical merit is had higher requirement.
The utility model content
To the problems referred to above, but the utility model aims to provide a kind of simple realization touch-screen evaluating apparatus break-make management, is used to control the touch-screen evaluating apparatus and correctly uses the Zero queuing machine system that touches evaluating apparatus.
For realizing this technical purpose; The scheme of the utility model is: a kind of Zero queuing machine system with touch-screen evaluating apparatus; Comprise the system control unit that is provided with the USB external-connected port, Zero queuing machine terminal, the evaluating apparatus that is connected with this unit; The terminal of this evaluating apparatus is a touch display screen; This display screen is connected through usb bus with system control unit, is serially connected with USB broken-circuit controller and touch screen controller between said system control unit and the touch display screen successively, and said system control unit is also through USB external-connected port control linkage USB broken-circuit controller.
As preferably, said USB broken-circuit controller comprises micro-control unit MCU, signal relay and USB bridge chip, and system control unit is connected with the MCU communication, and MUC is connected with signal relay.
As preferably, said signal relay adopts the relay of 3V as action execution unit, and to drive the triode forward conduction be that relay provides WV by drawing on the MUC.
This programme has been accomplished the control of physical link through unified software interface scheme is provided to the access rights control aspect of USB device; General USB device is passed through USB device signal broken-circuit controller; Can realize simply realizing control and management able to programme; Through the USB device physical connection is controlled, prevent the illegal operation of user to the touch-screen evaluating apparatus.
Description of drawings
Fig. 1 is the structured flowchart of the utility model;
Fig. 2 is the equivalent schematic diagram of the utility model USB switch module.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
As shown in Figure 1; A kind of Zero queuing machine system of the utility model with touch-screen evaluating apparatus; It comprises the system control unit that is provided with the USB external-connected port, Zero queuing machine terminal, the evaluating apparatus that is connected with this unit; The terminal of this evaluating apparatus is a touch display screen 1; This display screen 1 is connected through usb bus with system control unit 4 (being the PC in the drawing), is serially connected with USB broken-circuit controller 3 and touch screen controller 2 between said system control unit 4 and the touch display screen 1 successively, and said system control unit 4 is also through USB external-connected port control linkage USB broken-circuit controller 3.Normal use touch screen controller 2 is to be connected with system control unit 4 (being the PC in the drawing) through usb bus, and in order to reach switching function, the utility model has increased the USB isolating switch 3 of control able to programme, and its principle equivalence is as shown in Figure 2.
Existing with regard to the USB broken-circuit controller 3 in the utility model, promptly the composition of Universal USB device signal broken-circuit controller with realize principle, the table explanation is as follows in detail:
USB broken-circuit controller 3 is to adopt MUC+ signal relay+one or more usb signal circuits of USB bridge chip controls, and logical PC or other opertaing device carry out the switch control of one or more USB device.
In specific embodiment, it realizes that principle is:
1, PC and MUC communication
This controller carries out all interface control and managements by MUC-U4A, is responsible for being connected with PC through the PL2230HUSB chip.MUC realizes the instruction transmitting-receiving through USB and host communication.About searching automatically of this equipment.Lead to into searching of USB port, set up correct communication relation with shaking hands.
2, MUC is connected with signal relay
For the switching device of usb signal, used herein be the relay of 3V as action execution unit, by drawing the driving triode on the MUC P2 mouth, be that relay provides WV by the triode forward conduction.
3, PC and the usb signal control of opening circuit
Executive circuit is driven in the signal transmission and the pass that have been made up of the USB isolating switch above two parts circuit.Performance element has been arranged, and next PC will be set up the relation of shaking hands with MUC.Safer for the work of this equipment, consider that USB withdraws from unusually or other fault, guarantee the USB normal operation of circuit breaker, on PC software, increase monitoring.
The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection domain of the utility model technical scheme.
