Description
Technical field
The invention belongs to technical field of new energies, relating to a kind of is that master, common power supply are the air-conditioned bus scavenger fan power supply auto-control Design scheme of assisting with solar powered.
Background technology
In recent years, the problem of constantly increase in order to solve urban population, urban road is more and more crowded, each city has all been dropped into substantial contribution and has been developed the public transport of oneself, especially common ground public transport.When constantly expanding bus routes, increasing bus quantity, also, improve ride comfort constantly improving the environment by bus of bus, for example,, improve that air quality is exactly a kind of measure wherein in the car for air-conditioned bus provides scavenger fan.At present, most air-conditioned bus scavenger fans all are through mobile generator or storage battery power supply, and the required energy of mobile generator work is generally the petrochemical industry class A fuel A, comprises gasoline, diesel oil, natural gas etc.Yet on the one hand along with the arrival in soaring oil prices epoch, the cost of bus operation is increasingly high, and a lot of bus drivers close fan for fuel-economizing during often being chosen in operation; On the other hand, the pollution that the petrochemical industry class A fuel A is brought also can not be despised, and the hydrocarbon in the Vehicular exhaust, oxygen sulfur compound, oxynitrides and photochemical fog etc. have brought huge harm all for the mankind and environment.
Therefore; The present invention designs bus fan power supply automatic selective system, when the battery tension that is connected with solar panel is higher, then utilizes this storage battery to supply power for scavenger fan; And when this battery tension is low; Then utilizing solar panel is its charging, utilizes bus to carry storage battery simultaneously or generator is supplied power for scavenger fan, thus when ensureing environment inside car energy savings, reduce disposal of pollutants.
The present invention compares traditional air-conditioned bus powering mode, has following advantage:
(1) solar energy is a kind of reproducible clean energy resource, is electric energy with conversion of solar energy, can realize energy-conserving and environment-protective for scavenger fan provides power, reduces the purpose of air-conditioned bus operating cost.
(2) driver only need press control switch 1, and scavenger fan is just started working.When storage battery 1 dump energy more for a long time, it is fan power supply that system selects it automatically; Otherwise it is the fan power supply that storage battery 2 or generator are then selected by system.Whole control process does not need other manual operation, can try one's best when avoiding the people to be misoperation yet and not disperse driver's attentiveness.
(3) in the summer of sweltering heat, during engine stop working, also can utilize storage battery 1 or storage battery 2 to the scavenger fan power supply, reduce vehicle interior temperature, keep good ventilation, make the interior electronic devices and components of car avoid Yin Gaowen and influence its performance and useful life.
(4) control circuit is simple, and is easy to operate, with low cost, long service life.
(5) because the non-stop run of fan, the air-conditioned coach environment of riding can be greatly improved, and can attract more choose bus trips, alleviates traffic congestion, realizes green traffic.
(7) terminal voltage that can record storage battery 1 in real time of controller, thus the charging and discharging state of storage battery 1 controlled in real time, it is full of, crosses to put and take to automatically shut down and safeguard measure, thereby make it reach optimal operational condition, prolong its life-span.
Summary of the invention
In order to guarantee the air-conditioned bus inner air flow; Ensure that the passenger is physically and mentally healthy; And overcoming the problem that traditional air-conditioned bus scavenger fan supply power mode is single or supply power mode can not automatically switch, it is that master, common power supply are the air-conditioned bus scavenger fan automatic control module of assisting with solar powered that the present invention provides a kind of.
This module is through the operating state of switch 1 control scavenger fan system; Behind the artificial close switch K1, controller PIC 16F676 at first gathers the end gate voltage of storage battery 1, if voltage is higher than threshold value; Then control triode NPN2 closing relay K3; Control triode NPN3 breaks off relay K 4 and K2, utilizes storage battery 1 to the fan power supply, prevents that simultaneously storage battery 1 from overcharging.Otherwise, then control triode NPN1 closing relay K2, break off relay K 3, utilize storage battery 2 or generator to supply power to fan, control triode NPN3 closing relay K4 simultaneously, utilize solar panel to storage battery 1 charging.
