1  System Function Traits:

Stability:exclusive frequency detection and frequency hopping function to ensure the system not subject to any interference; system fault automatic diagnosis and timely repair to ensure system zero failure rate;system dormancy function to make sure the long usage time of system.electric quantity of battery dynamic display function and centralize shutdown function to ensure system stable,safe and reliable.system adopts anti-static design.

Data is accurate,safe:data encryption; the characteristics of authorization vote to ensure one person one vote,avoid man-made cheating and misoperation.

Operation with high security:complete achieve secret ballot;LCD and removability to ensure voting status not observe by others.

Function:has voting function;press key to sign in;count down hint function.

Simple operation,good applicability:each step operation has prompt,status display,easy to learn and visual directly,easy operate;wireless,can use in any conference room not change previous decorate style.

System maintenance, preserve are convenient:voting device is small in size,easy to keep and take;system is stable and reliable,small amount of routine maintenance.

2  System core advantage 

Intelligent LCD design:LCD not only display communication status,voting information but also has maintenance,information detection display-channel,voting device’s no,low voltage power off.

Voting flexibility:the voting issues can vote in any order, the voting process is also available for immediate add voting issue;

Split screen display:the display interface and operate interface can separately display,when not need to operate or in adjourn of voting issue,it can display conference title or issue etc.

Working mode:vote(favor,oppose,waiver),appraise(satisfied,most satisfied,not satisfied,waiver)grade(0-100 points),elect(during election process every voting device display the number that is optional, to ensure that there will be no invalidated ticket.

Software and hardware combined online mutual inspection function:largely improve the stability of system operation,automatic alarm when break down and indicate operator the reasons of problem to make sure rapidly removal of trouble,be convenient to maintain.

High capacity:every signal frequency can support maximum 250 voting devices to vote at the same time,fully satisfy all kinds of conference occasion.
