Abstract

The invention relates to the control field of radiating and ventilating facilities of engines of contact net operation vehicles, in particular to an automatic control device for a radiating and ventilating facility of an engine of a contact net operation vehicle. The radiating and ventilating facility of the engine of the contact net operation vehicle is controlled intelligently, the automatic control device comprises a master control module, a signal acquisition module, an actuating module and a power module, an output end of the signal acquisition module is connected with a signal acquisition input end of the master control module, a control signal input end of the actuating module is connected with a control signal output end of the master control module, the signal acquisition module comprises a signal processing circuit, a temperature sensor, a speed sensor and a direction distinguishing sensor, and output ends of the temperature sensor, the speed sensor and the direction distinguishing sensor are connected with the signal acquisition input end of the master control module by the signal processing circuit. The automatic control device for the radiating and ventilating facility of the engine of the contact net operation vehicle is reasonable in structure and fine in service effect, can effectively reduce work intensity of operators of the operation vehicle, and improves technological content of the contact net operation vehicle.

Description

technical field [0001] The invention relates to the control field of heat dissipation and ventilation facilities of an engine of a catenary operation vehicle, in particular to an automatic control device for the heat dissipation and ventilation facility of an engine of a catenary operation vehicle. Background technique [0002] Existing catenary vehicle engine cooling and ventilation facilities include shutters and small side doors, which are generally opened and closed by manual operation of the corresponding switches on the console in the cab, and according to the operating regulations of the operating vehicle: when the operating vehicle is driving forward, Only open the louvers in the engine cooling and ventilation facilities of the catenary operation vehicle to realize heat dissipation and ventilation; when the operation vehicle is driving in the reverse direction, only open the small side door in the engine cooling and ventilation facilities of the catenary operation veh...

Problems solved by technology

[0002] Existing catenary vehicle engine cooling and ventilation facilities include shutters and small side doors, which are generally opened and closed by manual operation of the corresponding switches on the console in the cab, and according to the operating regulations of the operating vehicle: when the operating vehicle is driving forward, Only open the louvers in the engine cooling and ventilation facilities of the catenary operation vehicle to realize heat dissipation and ventilation; when the operation vehicle is driving in the reverse direction, only open the small side door in the engine cooling and ventilation facilities of the catenary operation vehicle to achieve heat dissipation and ventilation; in short, the opening and closing timing, The opening and closing facilities are determined manually. Therefore, once the operator of the work vehicle forgets to operate or fails to operate the shutter or side door in time, or makes an operation error (that is, the shutter is not opened correctly when the work vehicle is driving forward; When the work vehicle is driving in the reverse direction, if the side door is not opened correctly), it will affect the heat dissipation effect of the locomotive engine and seriously cause engine damage

[0003] Although with the rise of the level of science and technology, the current control method for the cooling and ventilation facilities of the catenary operation vehicle engine has been developed towards the field of automatic control, but the parameters based on automatic control only use the engine coolant temperature, which makes the control method for the catenary operation vehicle engine The automatic control of heat dissipation and ventilation facilities is far from reaching the intelligent standard
