The invention provides a vehicle-mounted negative pressure control method and system, and the method comprises the steps: obtaining the negative pressure value of each position in a carriage, and calculating the average negative pressure value in the carriage; a set negative pressure value in the compartment is obtained according to user requirements, and if the set negative pressure value is larger than the negative pressure value, the two negative pressure devices are controlled to adjust the negative pressure value in the compartment at the same time so that the negative pressure value in the compartment can be increased; if the set negative pressure value is larger than the average negative pressure value, a negative pressure device is controlled to adjust the negative pressure value in the compartment, so that the negative pressure value in the compartment is increased; setting the lowest negative pressure value in the compartment, monitoring the negative pressure value in the compartment, and if the negative pressure value is larger than the lowest negative pressure value, controlling the two negative pressure devices to adjust the negative pressure value in the compartment at the same time so as to enable the negative pressure value in the compartment to be higher than the lowest negative pressure value. The negative pressure value of each position in the compartment and the average negative pressure value in the compartment can be adjusted, so that airflow in the compartment is smooth and not disordered, and the negative pressure value in the compartment can be conveniently adjusted.

    本发明提供一种车载负压的控制方法及系统,方法包括获取车厢内各个位置的负压值,并计算车厢内的平均负压值;根据用户需求得到车厢内的设定负压值,若设定负压值大于负压值,则控制两负压装置同时调节车厢内的负压值,以使车厢内的负压值增大;若设定负压值大于平均负压值,则控制其一负压装置调节车厢内的负压值,以使车厢内的负压值增大;设定车厢内最低负压值,并监控车厢内的负压值,若负压值大于最低负压值,则控制两负压装置同时调节车厢内的负压值,以使车厢内的负压值高于最低负压值。本发明能够调节车厢内各个位置的负压值以及车厢内的平均负压值,以使车厢内的气流平整不紊乱,并且能够便捷的调节车厢内的负压值。
