MDDV33/3 tabletop dual-core dual-channel electronic voting device
The voting machine is a voting terminal specially designed for the voting system. The shell is made of ABS plastic, the main body color is elegant black, and the middle waistline is matched with a silver-white frame, which is particularly modern. It is very light, and the four rubber nails at the bottom can place the voting machine on the desktop steadily and firmly. It is easier to operate. The voting machine is a dual-circuit board dual-core voting terminal specially designed for the voting system. The voting machine is designed with three voting keys, which are green, red and yellow, arranged from left to right, and the corresponding Chinese characters "yes", "no" and "abstain" are printed below. Each voting unit has two independent operating cores. When the representative presses the voting button, the two cores can collect the key data at the same time and transmit the data to the corresponding control computer respectively. Dual-channel independent data transmission. Even if any voting machine or even one voting machine fails or any host fails, it will not affect the normal use of the system.

The voting status indicator light distinguishes the different working states of the voting machine. The round button and the button surface are slightly concave, comfortable to touch, and ergonomically designed. The appearance design should be simple and generous, in line with the trend of the times, and adapted to the interior of the venue. Different functions can be completed according to different instructions, such as key registration before the meeting, public voting and secret voting, etc. Participants can use voting keys to participate in various agendas or interactions of the meeting.

Multi-layer PCB board process circuit board design, anti-static circuit and light guide and other anti-static designs make the equipment resistant to at least 12000V static electricity, avoiding damage to components due to static electricity. Greatly extend the service life of the voting machine.

Dual memory can store the last voting result, support unit voltage test to calculate the rationality of the number of voting machines connected to trunks of different lengths, and provide important guarantee for system security and reliability. Each device has a preset ID number when it leaves the factory, and the conference affairs group can change it according to actual use.

The finely crafted brushed panel is convenient for users to clean and organize the desktop. The sturdy appearance is particularly stylish. The system is connected hand in hand. There are two DB9PIN sockets with locks on the back of each device. Using the connection cable that comes with the device, the system can be quickly and firmly connected. Voters can be connected in series or in parallel, or in series and parallel. The construction is more flexible.
