Portable device of detecting passenger overcrowding in bus and pre-display system

Abstract

The object of the present invention is to provide a portable bus passenger congestion detection device and a pre-display system that are easy to carry and install, and can accurately detect the passenger congestion degree in the bus. The present invention includes a pressure detection device, a bottom plate, electric wires and an A / D converter; the pressure detection device includes an upper plate, a spring, a lower plate, an upper plate electrical contact, a lower plate electrical contact and a switch; The electric contact on the side wall of the groove and the electric contact on the bottom of the groove. There are at least three grooves on a bottom plate. The pressure detection device is placed in the groove. One pressure detection device corresponds to one groove. Groove size matches. The portable passenger congestion detection device in the bus and the preview system of the present invention can be placed on the upper door steps in the bus or in the passenger standing area in the bus.

Description

technical field [0001] The invention belongs to the field of bus technology, in particular to a portable bus passenger congestion detection device and a pre-display system. Background technique [0002] With the continuous development of my country's social economy, urban traffic problems are becoming more and more serious, and traffic congestion has become one of the hottest topics for urban residents. How to provide a convenient, fast, economical and safe travel environment for the society, improve traffic congestion and road congestion, become a common problem faced by many people. Buses are an important tool to alleviate urban traffic congestion, but due to the huge passenger flow, a series of problems often occur. When passengers are waiting for the bus, due to the unforeseen congestion situation in the car, it may happen that the vehicle they are taking is fully loaded and cannot get on the bus. At present, in the existing vehicle congestion situation prediction syste...

Problems solved by technology

However, there is a situation of uneven passenger weight. Large weight (high pressure) does not mean that there are many people, let alone crowded in the car. An adult weighing 100 kg will produce the same pressure as five children weighing 20 kg, but the former The area occupied may be only one-fifth of the latter, so the pressure cannot accurately predict the degree of congestion in the car, and cannot accurately guide passengers to ride

Moreover, the pressure sensor congestion detection system in the prior art has technical defects such as high cost, complicated laying procedures, and inconvenient repairs.
