Problems solved by technology

However, because it is always in the power-on state, the booster of the power supply circuit must work normally for a long time, and the long-term normal operation of the booster will cause high standby power consumption, and it is easy to cause battery power loss after the vehicle is parked for a long time

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0025] Such as figure 1 As shown, the present invention is a low-power standby control system for a vehicle-mounted oxygen generator, including a boost circuit and a control module. Wherein, the power supply circuit is connected between the vehicle battery and the oxygen generator, and the boost circuit is arranged in the power supply circuit of the vehicle oxygen generator.

[0026] The boosting circuit may be a PFC boosting circuit with PWM pulse width modulation boosting or a transformer boosting circuit. figure 2 The real-time scheme of the PFC boost circuit is shown, including the power input terminal, PFC inductor, switch, diode and power output terminal, one end of the PFC inductor is connected to the power input end, the...

Abstract

The invention relates to the technical field of automobile control, in particular to a low-power-consumption standby control system and method of a vehicle-mounted oxygen generator and a storage medium. The system comprises: a boost circuit used for regulating and controlling the power supply voltage of the vehicle-mounted oxygen generator according to the control instruction of the control module; and a control module which is used for controlling the booster circuit to work intermittently by taking t2 as a time interval when the oxygen generator is judged to be in the standby working condition, wherein the working duration of the booster circuit each time is t1. The boost circuit does not perform switching action within the second preset time, so that the driving times are reduced, and the switching-on and switching-off times of the switch are reduced. Therefore, the driving power consumption is reduced, and the purpose of reducing the standby power consumption of the vehicle-mounted oxygenerator is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a low-power standby control system, method and storage medium for a vehicle-mounted oxygen generator. Background technique [0002] The vehicle-mounted oxygen generator is a type of machine for producing oxygen on the vehicle. People usually use the vehicle-mounted oxygen generator to release oxygen to increase the oxygen content in the cab. Increasing the oxygen content in the cab is beneficial to the driver's health, especially for long-distance drivers, which can effectively help them dispel sleepiness, keep a fresh mind and drive the vehicle, and avoid car accidents. At present, the widely used oxygen production method is the molecular sieve oxygen production method, which separates oxygen and nitrogen in the air through molecular sieve pressure adsorption. [0003] Vehicle-mounted oxygen concentrators are usually used by truck drivers who drive long-distance larg...
