How much does it cost to install elevators in old buildings? The 6-story old building needs an elevator.

When installing elevators, except for government subsidies, the money is raised by residents themselves, and the prices on different floors are different. Checked the information at that time, when Xinmin Village installed the elevator, it agreed on the investment ratio:

There is no need to pay for the first floor and the second floor. Third floor 10% (25,500 yuan for one household), fourth floor 20% (5 1000 yuan for one household), fifth floor 30% (76,500 yuan for one household) and sixth floor 40% (0/02,000 yuan for one household).

Select the correct option:

A. domestic elevator door opening methods are divided into sliding doors and automatic doors:

The structure of the sliding door is similar to that of the door commonly used in our family, but it is heavier with more door locks. At the same time, the sliding door has no door protection design, which objectively has security risks.

Automatic doors, like public passenger elevators, have double protection of car doors and hall doors. The difference is that more than 95% of villa elevators choose automatic doors with side doors because they can save the building area to the maximum extent, make full use of the width of the shaft, and make it convenient for the disabled and the elderly to use, which fully reflects their profitability.

B, choose the villa elevator controlled by PLC or microcomputer:

PLC control is the abbreviation of English "Programmable Logic Controllers", that is, programmable logic controllers, which are mainly used in early industrial fields and are also the main control methods of elevators.

In 1980s, when microcomputer control system appeared, PLC control was widely used in elevator field, but it was completely eliminated in passenger elevator field. Therefore, it is the right choice to choose a precise microcomputer control system.
