Description
Technical field
The utility model belongs to electric automobile air conditioner electric control module technical field, particularly a kind of automatic speed governing device of electric motor coach blower fan.
Background technique
Use adhesive and the open circuit of Control blower fan place circuit in current trolley air conditioner device, make blower fan work plant-grid connection in the circuit of different resistance, thus change the current value of blower fan place circuit, reach the object of fan speed regulation.
The mode of this control relay circuit controls rotation speed of fan and blows, and generally only has 3 kinds of velocity modes available, cannot meet the adjustment of passenger for adaptive temperature.The usability of corresponding part and working life are produced a very large impact due to the notable change of excess current amount when carrying out regulating wind speed in addition.In addition, the effect using resistance to reach pressure drop makes electric car electricity waste to some extent to a certain extent, and resistance can cause heating after working long hours, the damage of electric original paper near likely causing.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of automatic speed governing device of electric motor coach blower fan, to reducing energy consumption, realizes automatic speed regulation to blower fan.
The technological scheme that the utility model is taked is:
An automatic speed governing device for electric motor coach blower fan, is characterized in that, comprises control gear and signal pickup assembly, and described control gear comprises control panel, PLC module and frequency variator; Described signal pickup assembly comprises temperature monitoring, described Temperature Detector is electrically connected with PLC module input end, described PLC module output terminal is electrically connected with control gear, frequency variator respectively, described Temperature Detector is installed in electric motor coach, described PLC module receives the temperature information of described Temperature Detector and is sent to control panel, and described control panel makes described PLC module control the rotating speed of described frequency variator to described blower fan according to described temperature information to regulate.
Further, described PLC module inside is provided with semiconductor cooler.
Further, described frequency variator is Delta VFD037E43A 3.7KW frequency variator.
Further, described PLC module also comprises fault emergency processing circuit.
The beneficial effects of the utility model are:
(1) improve the control to vehicle interior temperature.By the information feed back of temperature monitoring, PLC module can regulate the motion speed of blower fan voluntarily by set program;
(2) by adopting PLC module to make arrangements for speed regulation antijamming capability strong, failure rate is low, be convenient to safeguard, the construction cycle is short;
(3) avoid after reaching target temperature, the energy waste that blower fan full speed running causes.PLC module reduces the running speed of blower fan after can passing through can to reach target temperature in car to the process of temperature signal;
(4) eliminate rheostatic speed regulation originally and change PLC speed governing into, improve the flying power of electric car to a certain extent, saved the consumption of electricity.
Accompanying drawing explanation
Accompanying drawing 1 is module diagram of the present utility model;
Label in accompanying drawing is respectively:
1. control panel; 2. PLC module;
3. Temperature Detector; 4. frequency variator;
5. blower fan.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the automatic speed governing device of the utility model electric motor coach blower fan.
See accompanying drawing 1, the automatic speed governing device of electric motor coach blower fan comprises control gear and signal pickup assembly, and described control gear comprises control panel 1, PLC module 2, frequency variator 4.Described model collecting device comprises temperature monitoring 3, and described Temperature Detector 3 is electrically connected with PLC module 2 input end, described PLC module 2 output terminal respectively with control panel 1, frequency variator 4 is electrically connected.
Working procedure of the present utility model is as follows, temperature signal in Temperature Detector 3 pairs of cars gathers, these non-electric charge quantity signallings are transferred to PLC module 2 process, carry out detecting and reporting to the police finally by control panel 1, utilize the control of frequency variator 3 pairs of output voltages, reach and regulate blower fan 5 speed, regulate the effect of vehicle interior temperature further.
Described temperature monitoring 3 selects self-control temperature sensor assembly.Comprise monitoring return air temperature and outdoor temperature.And temperature signal is passed to PLC module 2, be connected with PLC module 2.Described PLC module 2 inside is provided with semiconductor cooler, makes the utility model still can safe and stable operation in summer high temperature situation.Described PLC module 2 configures two PLC fault emergency processing circuit, improve reliability and the Security of system cloud gray model, described PLC module is provided with intelligent controlling device, passes through intelligent controlling device, can realize controlling the output signal of PLC module, and by signal transmission to frequency variator 4.Described frequency variator 4 uses Delta VFD037E43A 3.7KW frequency variator, by programming voluntarily to actual service condition to the needs of different electric car type.And output current is sent to blower fan 5.
By above improvement, the interior environment by bus of electric car obtains and improves significantly, by the target temperature that control panel sets, signal transmission is to after PLC module, the temperature signal that PLC module is returned by device for detecting temperature, gives frequency variator corresponding output signal, after frequency variator receives signal, regulate the motion speed of blower fan according to the executive routine inculcated, thus play the effect controlling vehicle interior temperature.
Below be only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
