The invention discloses a mobile laboratory and a negative pressure control method and device.The mobile laboratory comprises at least two subareas, an air feeder and an exhaust fan, the air feeder is communicated with the subareas of the mobile laboratory through air supply pipes, and the exhaust fan is communicated with the subareas of the mobile laboratory through exhaust pipes; an air volume valve is arranged on the exhaust pipe of each subarea, and a pressure difference sensor is further arranged in each subarea. The negative pressure control method of the mobile laboratory comprises the following steps: collecting an actual pressure difference of a to-be-adjusted partition; judging whether the actual pressure difference belongs to a pressure difference range corresponding to the to-be-adjusted partition or not; when the actual pressure difference does not belong to the pressure difference range, the opening degree of an air volume valve in the to-be-adjusted partition is obtained, and whether the opening degree of the air volume valve is adjustable or not is judged; when the air volume valve is adjustable, the opening degree of the air volume valve is adjusted. Therefore, the negative pressure control of each subarea in the mobile laboratory is relatively independent, and the targeted accurate control of the negative pressure of the mobile laboratory is realized.
本发明公开了一种移动实验室、移动实验室的负压控制方法及装置,其中移动实验室包括至少两个分区、送风机和排风机,送风机通过送风管与移动实验室的各个分区连通,排风机通过排风管与移动实验室的各个分区连通,在各个分区的排风管上均设有风量阀门,在各个分区中还设有压差传感器。移动实验室的负压控制方法包括:获取待调整分区的实际压差;判断实际压差是否属于与待调整分区相对应的压差范围;当实际压差不属于压差范围时,获取待调整分区中风量阀门的开度,并判断风量阀门的开度是否可调;当风量阀门可调时,调整风量阀门的开度。由此可以使得移动实验室中各个分区的负压控制相对独立,实现移动实验室负压有针对性的精确控制。
