Description

Technical Field

[0001] The invention relates to the field of air conditioning, and in particular to a driver's room temperature control system based on hybrid energy supply. Background Art

[0002] In locomotive electricity consumption, electric heater is an important function that consumes a large amount of electricity and wastes a lot of resources. In hybrid vehicles, the heating control of the electric heater is often based on the same power supply method, which leads to excessive power consumption burden of this type of power supply method. It requires a long time for stable power supply and endurance, which is not conducive to the stable operation of hybrid energy locomotives.

[0003] At present, in the field of rail transit, most of the domestic locomotive driver's cab heating systems contain variable frequency air conditioners, heaters, knee stoves, foot stoves and other heating devices to ensure the working temperature environment of drivers and passengers in low temperature weather. When the weather is cold, the driver and passengers need to manually operate the air conditioners, heaters, knee stoves, foot stoves and other heating devices, but the manual operation of the air conditioners, heaters, knee stoves, foot stoves and other heating devices is used in conjunction with the use of the current driver's room temperature control. The temperature is often adjusted based on the ambient temperature, which often does not reach the temperature expected by the driver and passengers, and cannot ensure a comfortable working temperature. In addition, excessive activation and unreasonable use of heating devices will cause energy waste.

[0004] The existing patent CN213705422U discloses a temperature control system for the driver's room of an electric locomotive. The electric locomotive is provided with an auxiliary power supply system, and a plurality of heating devices are provided in the driver's cab; it also includes a temperature setting device, a controller, a switch device for controlling the working state of each heating device, a first temperature monitoring device for monitoring the ambient temperature of the driver's cab, and a second temperature monitoring device for monitoring the local temperature of the driver's cab; the power supply end of each heating device is electrically connected to the auxiliary power supply system through the switch device, the temperature setting device, the first temperature monitoring device, and the second temperature monitoring device are electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the control end of the switch device.

[0005] Although it uses a controllable method of ambient temperature and local temperature to achieve uniform temperature control, since the staff often move around and the fixed heat source will inevitably cause uneven heating, in actual experience, it is still difficult for the staff to obtain a reasonable working temperature environment.

[0006] Therefore, a driver room temperature control system based on hybrid energy supply is needed to solve the above problems. Summary of the invention

The body temperature module receives data from the indoor wind speed monitoring module and the in-vehicle humidity monitoring module, and the ambient temperature module receives data from the ambient humidity monitoring module.

[0010] The heated foot pedal is powered by the battery in the hybrid vehicle and the battery power ratio is increased when the heated foot pedal duration exceeds a threshold. The electric window control is powered by the pantograph in the locomotive hybrid vehicle.

[0011] The driver's room temperature control system based on hybrid energy supply described in the present invention, as a preferred embodiment, also includes an in-vehicle air supply mechanism, the air supply mechanism is a normal temperature ventilation system with an outlet arranged in the driver's room, and the control end of the air supply mechanism is connected to the temperature control module.

At the same time, this technical solution also considers heat influencing factors other than temperature, as well as the effect of Helmholtz resonance on the heat removed by ventilation, making the overall temperature adjustment more reasonable and closer to human perception.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1

[0036] like Figure 1As shown, a driver's room temperature control system based on hybrid energy supply includes a temperature control module 1, a heating pedal 2, an electric window 3, a vehicle speed monitoring module 4, a body temperature module 5, an indoor wind speed monitoring module 6, an ambient temperature module 7, a temperature monitoring module 8, an in-car humidity monitoring module 9 and an ambient humidity monitoring module 10.

The body temperature module 5 is used to calculate the real-time body temperature, the ambient temperature module 7 is used to determine the ambient temperature in real time, and the ambient humidity monitoring module 10 is a humidity sensor arranged outside the car body.

[0043] S3, the temperature control module 1 controls the heating foot pedal 2 to adjust the temperature to the ambient temperature module 7 detection data is within the ambient temperature threshold;

[0044] S4, determining whether the humidity in the driver's room is between 40% and 70%, if yes, adjusting the ambient temperature to between 18 and 25 degrees and proceeding to step S11, otherwise proceeding to step S5;

[0045] S5, the body temperature module 5 calculates the current body temperature in the driver's room. The body temperature calculation formula is as follows:

[0046]

[0047] Among them, AT is the perceived temperature, T is the ambient temperature, V is the wind speed, and RH is the relative humidity;

[0050] S8, determining whether the current body temperature is greater than the upper limit of the body temperature threshold, if yes, proceed to step S9, otherwise, adjust the window size of the electric window 3;

[0051] S9, adjust the temperature of heating pedal 2;

[0052] S10, determining whether the difference between the current body temperature and the ambient temperature is less than three degrees Celsius, if yes, proceed to step S11, otherwise proceed to step S3;

[0053] S11, determine whether the locomotive is still running, if yes, proceed to step S4, otherwise end the temperature adjustment.

[0054] Furthermore, when the window is open, the humidity in the driver's cabin is based on the ambient humidity measured by the ambient humidity monitoring module 10 .
