Problems solved by technology

However, with the continuous development of the city, the number of buses has increased rapidly. Every time when starting, accelerating, turning or going uphill, these diesel vehicles will inevitably emit black smoke, causing a lot of pollution to the environment
At the same time, the cost of new energy buses is high, and many bus companies are discouraged from buying and repairing them.

Embodiment Construction

[0016] The motor vehicle exhaust telemetry equipment distribution method based on graph theory and Boolean algebra proposed by the present invention aims at real-time and efficient monitoring of bus exhaust emissions. According to graph theory and Boolean algebra related theories, mathematical modeling and solving are carried out, and then the machine is researched. The deployment of high-speed train exhaust telemetry equipment in the urban traffic network.

[0017] Such as figure 1 Shown, the specific implementation steps of the present invention are as follows:

[0018] (1) The bus route is abstracted into a bus route hypergraph.

[0019] In graph theory, there is the following definition of a hypergraph:

[0020] Let V={v 1 ,v 2 ,...,v n} is a finite set, then a hypergraph H on V={E 1 ,E 2 ,...,E m} is a finite subset cluster on V such that (1)E i ≠Φ(i=1,2,…,m)(2) where v i is the i-th vertex of the hypergraph H, V is the set of vertices, E i is the i-th hypere...

Abstract

The invention relates to a graph theory and Boolean algebra-based position arrangement method for automotive exhaust remote measurement devices. For urban buses, the arrangement positions of the automotive exhaust remote measurement devices in an urban road network are searched for to achieve the goal of real-time efficient monitoring of bus exhaust emission situations. The method comprises the steps of firstly, based on a hypergraph related principle in a graph theory, converting a bus running route into a bus route hypergraph, and converting a position arrangement problem of bus exhaust remote measurement devices into a minimum transverse solving problem of the bus route hypergraph according to minimum transverse and transverse hypergraph concepts; secondly, working out all minimum transverse sets of the bus route hypergraph by using a Boolean algebra related principle; and finally, obtaining the minimum transverse sets, namely, minimum monitored road section sets, of the bus route hypergraph, and determining the arrangement positions of the bus exhaust remote measurement devices in the urban road network. Compared with an existing monitor position arrangement scheme, the method specially aims at an urban bus system and is more unique; a solving algorithm is simple and easy to realize; and the method is better in operability.

Description

technical field [0001] The invention relates to a point layout method of motor vehicle exhaust telemetry equipment based on graph theory and Boolean algebra, which belongs to the technical field of motor vehicle exhaust remote measurement equipment, aims at real-time and efficient monitoring of bus exhaust emissions, and is based on the correlation between graph theory and Boolean algebra Carry out mathematical modeling and solving, and then study the layout of motor vehicle exhaust telemetry equipment in the urban traffic network. Background technique [0002] With social development and urban progress, as high-pollution factories gradually move to the suburbs, away from the city, the number of motor vehicles in the city continues to increase. While promoting economic prosperity and bringing convenience to people's lives, automobiles have also brought energy and environmental issues. Among them, the biggest impact on the environment is the increasingly serious automobile e...
