[0034] Such as Figure 1As shown in the figure, this embodiment includes an in-vehicle intelligent gateway for receiving and processing the signals of the entire sanitation operation vehicle, and also includes a sanitation platform for monitoring and managing the signals of the entire sanitation operation vehicle.
