[0029] like Figure 1 As shown, Figure 1 This is a flow chart of an intelligent unattended weighing system according to an embodiment of the present invention;

[0030] Reference Figure 1 , an intelligent unattended weighing system proposed in an embodiment of the present invention comprises:

[0031] It includes a floor scale 8, an automatic reading and writing unit, a first cleaning mechanism and a control unit;

[0032] The first cleaning mechanism comprises a first driving member 1, a winding member 3 and a second driving member 2, wherein the winding member 3 is laid flat on the weighing area of ​​the floor scale 8, the first driving member 1 is arranged on one side of the floor scale 8, and the rotating shaft of the first driving member 1 is connected to one side of the winding member 3, the second driving member 2 is arranged opposite to the first driving member 1, and the rotating shaft of the second driving member 2 is connected to the other side of the winding member 3;

[0033] The control unit is electrically connected to the floor scale 8, the automatic reading and writing unit, the first driving motor and the second driving motor respectively;

[0034] The automatic reading and writing unit is used to read the RFID electronic tag information on the vehicle in the weighing area and upload the RFID electronic tag information to the control unit;

[0035] The weighbridge 8 is used to weigh the vehicle and upload the weighing data to the control unit;

[0036] The control unit is used to receive RFID electronic tags and weighing data, verify vehicle transportation information, verify the release of vehicles by controlling the exit gate, and is also used to control the first driving member 1 and the second driving member 2 to start when receiving a vehicle departure signal so that the winding member 3 is wound along a preset direction.

[0037] Usually, after the current vehicle weighing is completed and the exit gate releases the vehicle, the sensor system at the exit gate detects that the vehicle has left, or after the exit gate is lowered, a vehicle departure signal is generated, and the control unit will control the first drive member 1 and the second drive member 2 to start, and the rotating shafts of the first drive member 1 and the second drive member 2 rotate, so that the winding member 3 is wound along a preset direction, and can be wound on the outer periphery of the rotating shaft of the first drive member 1, or on the outer periphery of the rotating shaft of the second drive member 2. In this way, most of the coal and dirt on the winding member 3 will fall off the outer periphery of the floor scale 8, and the coal and dirt are not strongly adhered to the surface of the winding member 3.

[0038] As a preferred embodiment, a first curvature transition block 4 is provided on one side of the floor scale 8, and a second curvature transition block 5 is provided on the other side of the floor scale 8, and the upper end surfaces of the first curvature transition block 4 and the second curvature transition block 5 are tangent to the weighing area plane of the floor scale 8.

[0039] Through the first arc-shaped transition block and the second arc-shaped transition block, a smooth transition between one side of the winding member 3 and one side of the floor scale 8 and a smooth transition between the other side of the winding member 3 and the other side of the floor scale 8 are achieved.

[0040] Furthermore, the first arc transition block 4 and the second arc transition block 5 are inclined downward away from the side of the scale 8. Then the side of the winding member 3 away from the scale 8 is inclined downward relative to the scale 8, so that coal and dirt fall to the ground during the winding process of the winding member 3.

[0041] As a preferred embodiment, it also includes a second cleaning mechanism. The second cleaning mechanism is provided on the outer side of the first driving member 1 and / or the second driving member 2. The second cleaning mechanism includes a scraper member 6, an elastic member and a fixed seat 7. The fixed seat 7 is provided with a telescopic channel. The elastic member is installed in the telescopic channel. One end of the scraper member 6 is connected to the elastic member, and the other end of the scraper member 6 abuts against one side of the winding member 3. The elastic member provides a force that drives the scraper member 6 to maintain abutment with the winding member 3.

[0042] By adding a second cleaning mechanism, it is convenient to forcefully clean off the coal and dirt adhering to the winding member 3. The scraper member 6 is always in contact with the inclined side of the winding member 3. During the winding process of the winding member 3, the coal and dirt move toward the scraper member 6. After approaching the scraper member 6, they are scraped off by the scraper member 6. A large amount of coal and dirt on the winding member 3 is removed to avoid affecting the weighing data of the next vehicle.

[0043] As a preferred embodiment, the elastic member is a spring or a highly elastic rubber.

[0044] As a preferred embodiment, the first driving member 1 or the second driving member 2 is one of a motor and a rotary cylinder. Usually, the output shaft of the motor is connected to the rotating cylinder / rotating rod, one side of the winding member 3 is fixed on the rotating cylinder / rotating rod of the first driving member 1, and the other side of the winding member 3 is fixed on the rotating cylinder / rotating rod of the second driving member 2. The first driving member 1 and the second driving member 2 rotate to control the tension of the winding member 3 so that the winding member 3 can be laid flat on the surface of the weighing area of ​​the floor scale 8. At the same time, when the floor scale 8 is cleaned, the first driving member 1 and the second driving member 2 rotate at the same time so that the winding member 3 is wound along a preset direction, which can be a clockwise direction. The winding member 3 is wound on the output shaft of the first driving member 1 or on the rotating cylinder / rotating rod connected to the output shaft. The preset direction can also be a counterclockwise direction. The winding member 3 is wound on the output shaft of the second driving member 2 or on the rotating cylinder / rotating rod connected to the output shaft.

[0045] As a preferred embodiment, the control unit is also used to control the automatic read-write unit to write the weighing data into the RFID electronic tag after the vehicle transportation information is verified.

[0046] As a preferred embodiment, an RFID electronic tag is installed at the rear of the vehicle, and the automatic read-write unit is installed near the exit gate. When the vehicle completely enters the weighing area of ​​the scale 8, the automatic read-write unit reads the RFID electronic tag information.
