If so, arranging a transport vehicle to transport the garbage in the garbage compression bin to a garbage disposal plant; if not, continuing to wait for charging. Specifically, the transport vehicle can be arranged to directly transport the fully loaded garbage compression bin to a garbage disposal plant, and a new garbage compression bin is replaced at a corresponding bin position; compressed garbage blocks can be taken out from the garbage compression bin, so that the garbage compression bin is emptied, and the emptied garbage compression bin enters the next charging compression period. In addition, the transport vehicle and the garbage truck are different, and the loading capacity of the transport vehicle is far larger than that of a common garbage truck; to the whole condition of directly transporting in rubbish compression storehouse, can be split type with rubbish compression storehouse design, compression storehouse full load back can whole transfer, secondary when can avoiding rubbish transfer like this loads and unloads, reduces the intermediate link, improves rubbish transfer efficiency

The working state information includes to-be-loaded, to-be-transferred and to-be-stopped, for example, in fig. 2, the first to last bin is a new bin, and the working state is to-be-loaded; the first bin of the second row is in an abnormal state, and the second row is to be manually processed in the alarm prompt; the other bins are all in a deactivated state and are fully loaded, awaiting for the arrangement of the transport vehicle to transfer the compressed waste to the waste disposal plant. The indicating information comprises a loading capacity indicating strip and a working state indicating lamp, for example, in fig. 2, a vertical strip grid in each bin display screen is the loading capacity indicating strip and indicates the quantity of the loaded garbage; the working state indicator lamp in the display screen of the storage bin can adopt a red light and a green light to represent, the red light represents the work suspension, and the green light represents the normal work. Other information includes current date, indoor and outdoor real-time temperature, humidity, weather conditions, etc.
The measuring mode of the stock bin supervision unit is as follows: in specific implementation, the bin monitoring equipment can be a camera and a weight scale, and the current loading capacity of the garbage compression bin can be quickly and conveniently judged by taking pictures of the interior of the bin through the camera and weighing the weight; the bin monitoring equipment can be a plurality of touch sensors and a weight scale, the touch sensors are vertically and equidistantly arranged on the inner side wall of the bin, and the current loading capacity in the bin is calculated by analyzing signals collected by the touch sensors and combining weighing weight; the bin monitoring device can be an ultrasonic sensor and a weight scale and comprises an ultrasonic transmitter and an ultrasonic receiver, the sound waves are reflected when encountering garbage in the bin, and the current loading capacity in the bin is calculated by calculating the flight time of the ultrasonic waves and weighing the weight.
The method mainly judges whether the rated load capacity of the bin is achieved according to the weight of the garbage in the bin, and can also judge according to the charge volume of the bin, for example, the charge volume of the bin is detected by adopting image recognition, a stroke sensor/switch, ultrasonic waves and the like. If the two modes are combined, whether the volume of the garbage in the bin reaches the rated volume of the bin can be judged, if yes, the bin is considered to be fully loaded even if the weight of the garbage in the bin does not reach the rated value; if not, judging according to the weight of the garbage in the bin. In the above intelligent control method of a refuse transfer station, referring to fig. 3, the allocating an appropriate refuse compression bin to a refuse truck according to the refuse load of the refuse truck and the current load of each refuse compression bin, which are obtained by the automatic metering unit, includes:
the method comprises the steps that the garbage loading capacity of a garbage truck is obtained through an automatic metering unit, the current loading capacity of a garbage compression bin is obtained through bin monitoring equipment, and the residual loading capacity of the garbage compression bin is obtained;

In specific implementation, the preset minimum remaining load refers to the capacity of the garbage truck with the minimum loading capacity. The distribution rule for distributing the proper unloading bin position for each garbage truck is as follows: firstly, one of the garbage compression bins is preferably filled as much as possible, and if the garbage compression bin cannot be filled, the remaining space of the garbage compression bin can accommodate the conveying amount of the smallest garbage conveying vehicle. The method is specifically divided into the following three cases:
1. after the garbage conveyed by the current garbage truck is unloaded, the current loading capacity of the garbage compression bin just reaches the full loading capacity. For example, the theoretical loading capacity of the garbage compression bin is 15000KG, a full-loading capacity judgment range value of 14500 KG-15500 KG can be set, and when the current loading capacity of the garbage compression bin is within a range of 14500 KG-15500 KG, the garbage compression bin is judged to be fully loaded.
2. After the garbage conveyed by the current garbage truck is discharged, the residual loading capacity of the garbage compression bin can also accommodate the conveying capacity of the smallest garbage truck. For example, the minimum loading capacity of the garbage transport vehicle is 1000KG ± 200KG, then the minimum transport capacity is set to be 1000KG, and the rated loading capacity of the garbage compression bin is 15000 KG.
