Elevator car, video transmission system and method of elevator car

Abstract

The invention discloses an elevator car and its video transmission system and method. The car includes: a lighting switch and a controller. A lighting lamp is installed on the inner top wall of the elevator car. Human body infrared sensors are installed on the left, back and right sides of the interior, the lighting switch and controller are respectively installed on the left side and the right side of the elevator car, the lighting lamp is electrically connected to the lighting switch, and the lighting switch and human body infrared sensor are electrically connected to the controller. It has the advantages of energy saving and environmental protection, low cost, high safety, reliability and strong anti-interference ability.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator car and its video transmission system and method. Background technique [0002] With the rapid economic development and the continuous deepening of the urbanization process, my country's elevator industry is experiencing a period of rapid development. my country's elevator production increased from 10,300 units in 1990 to 365,000 units in 2010, with a compound annual growth rate of 19.5%. Domestic elevator demand increased from only 37,200 units in 2000 to 329,700 units in 2010. , The number of elevators in my country exceeds 1.6 million units. For details, please refer to the "China Elevator Industry Market Demand Forecast and Investment Opportunity Analysis Report". [0003] As the main tool for carrying passengers / goods in high-rise buildings, elevators will be used more and more widely in the future. It is the most common public place, so it is necessary to inst...

Problems solved by technology

However, the elevator shaft is a relatively complex environment. The video surveillance images of many projects are interfered to varying degrees in the elevator shaft environment. This has always been one of the most common, difficult to deal with, and one of the most concerned problems.

[0004] In addition, the current elevator monitoring network signal transmission still has the following two problems: First, the hoistway environment interference of elevator operation is very serious, how to reduce the loss of network signals has always been a problem; second, the well construction conditions of elevator operation are poor, if Upgrade the original analog monitoring to network monitoring. The traditional non-standard solution of binding the network cable to the accompanying cable is high in cost and poor in reliability. It has always hindered the upgrade of elevator monitoring; the third is the signal transmission from the elevator car to the monitoring room The distance is long, and the signal cannot be transmitted to the computer room stably and clearly, which also plagues the construction project
