Detailed schemes of the wagon balance weighing method, system and storage medium according to the embodiments of the present invention are described below with reference to fig. 1 to 7.

Referring to fig. 1, an embodiment of the present invention provides a wagon balance weighing method, which may be performed by a control device connected to a wagon balance, an infrared vehicle separator provided at both ends of the wagon balance, a vehicle recognition device provided near both ends of the wagon balance, and an image pickup device provided at least one side of the wagon balance, respectively; the method specifically comprises the following steps:

step 110: and judging whether the vehicle to be weighed has weighing authority according to the identification information of the vehicle to be weighed, which is uploaded by the vehicle identification equipment, and obtaining an authority judging result.

It is understood that the identification information of the vehicle to be weighed may be a license plate number, a vehicle number, a driver's work number, or the like, which can uniquely characterize the identity of the vehicle.

In practical application, if the identification information is license plate number, the vehicle identification equipment can be a license plate identification barrier gate integrated machine; the vehicle identification device may be a card reader if the identification information is a vehicle number or a driver's job number, etc.

In some embodiments, the identification information uploaded by the vehicle identification device may be compared with data in the vehicle identification database, and if the vehicle identification information can be matched with the corresponding vehicle identification in the vehicle identification database, it may be determined that the vehicle to be weighed has the weighing authority; otherwise, the vehicle to be weighed can be judged to have no weighing authority.

Step 120: and if the authority judgment result is that the vehicle to be weighed has the weighing authority, judging whether the vehicle to be weighed is in the weighing area or not according to the infrared detection data uploaded by the infrared vehicle separator, and obtaining a position judgment result.

In this embodiment, the infrared detection data at two ends of the wagon balance can be collected through the vehicle separator, and then the control device can judge whether the vehicle to be weighed is in the weighing area according to the infrared detection data, if the vehicle is not in the weighing area, the weight data collected by the wagon balance at the moment is inaccurate, a certain error exists, and after the vehicle is required to drive into the weighing area, the more accurate weight data can be collected.

Step 130: and if the position judgment result shows that the vehicle to be weighed is in the weighing area, determining the weight of the goods according to the actual measured weight uploaded by the wagon balance and the pre-stored empty weight of the vehicle to be weighed.

It will be appreciated that the weighing vehicle may be driven into the weighing area of the wagon balance to weigh before loading the load, and then empty load weight may be obtained, and then the vehicle may be driven into the loading and unloading area to load the load, and then twice weighing may be performed, and then actual weight may be obtained, and the actual weight and the empty load weight may be differed, and the load weight may be calculated.

In some embodiments, the empty load may also be obtained according to a vehicle type of the vehicle to be weighed, for example, in a logistics transportation scenario configured with a unified logistics vehicle, because the logistics vehicle type number is unified, the empty load of the logistics vehicle may be stored in advance, and then when the weight of the cargo is determined, the empty load may be directly called for obtaining the calculation of the weight.

Step 140: and judging whether the weighing process of the vehicle to be weighed is abnormal or not according to the image information of the vehicle to be weighed, which is uploaded by the image acquisition equipment, so as to obtain an abnormal judgment result.

In this embodiment, the image acquisition device may acquire image information around the wagon balance, and the control device may further determine whether there is an abnormality in the weighing process of the vehicle by performing analysis processing on the image information. For example, it may be determined whether a rear vehicle is too close to the vehicle to be weighed in the weighing area in the weighing process, and a rear vehicle weight phenomenon occurs, or whether a foreign object shields a license plate in the weighing process.

If the weighing process is abnormal, the weight data acquired by the wagon balance is possibly deviated, so that the abnormal phenomenon in the weighing process can be detected by the image acquisition equipment in a mode of detecting the abnormality of the weighing process, and the authenticity and the reliability of the weighing process are ensured.

Step 150: if the abnormal judgment result is negative, taking the weight of the goods as a weighing result.

It can be understood that under the condition of ensuring that the weighing process is not abnormal, the weight of the goods can be finally used as a weighing result, and the weighing result is obtained after passing through a judgment link, so that the authenticity, accuracy and reliability of the weighing result are higher.

In an embodiment, determining whether the vehicle to be weighed is in the weighing area according to the infrared detection data uploaded by the infrared vehicle separator specifically includes:

if the fact that the vehicle is driven into the weighing area is determined according to the infrared detection data uploaded by the infrared vehicle separator, and the infrared vehicle separator is not shielded for more than the first set time length, the vehicle to be weighed is judged to be in the weighing area.

If the fact that the vehicle is driven into the weighing area is determined according to the infrared detection data uploaded by the infrared vehicle separator, and the infrared vehicle separator is shielded for more than the second set time period, the vehicle to be weighed is judged not to be in the weighing area.

In this embodiment, the infrared vehicle separator is installed in the both ends of weighbridge respectively, and infrared vehicle separator can gather the infrared detection data in the left side and the right side of weighing area, and the control device can judge whether wait to weigh the vehicle in weighing area according to infrared detection data.

Fig. 2 exemplarily shows a situation in which a vehicle to be weighed is in a weighing area, in which neither of the infrared vehicle separators at both ends is shielded, and when the control device detects that the time of the non-shielding exceeds a first set period of time, it may be determined that the vehicle to be weighed is in the weighing area.

Fig. 3 illustrates an exemplary case in which the vehicle to be weighed is not in the weighing area, in which case the right-side infrared vehicle separator is blocked, and if the control device detects that the blocked time exceeds the second set period of time, it may be determined that the vehicle to be weighed is not in the weighing area.

Fig. 4 illustrates another situation in which the vehicle to be weighed is not in the weighing area, and in this case, although the vehicle to be weighed has entered the weighing area, there is a situation in which the rear vehicle is pressed against the weight, at this time, it may be detected that the right-side infrared vehicle separator is blocked, and if the blocking time exceeds the second set time period, it may still be determined that the vehicle to be weighed is not driven into the weighing area.

It can be understood that, because the vehicle to be weighed is driven into the weighing area on the wagon balance, the infrared vehicle separator at least one end can detect that the vehicle is driven through, in order to avoid the problem that the control device misjudges because the vehicle is driven slowly, the embodiment sets two time thresholds of the first set time and the second set time, and after the shielding or non-shielding is detected to exceed the corresponding set time, the position judging result can be obtained, thereby improving the accuracy of the position judging result.

In an embodiment, the control device is further connected to an electronic screen disposed on at least one side of the wagon balance, and after determining that the vehicle to be weighed is not in the weighing area, the wagon balance weighing method may further include:

and sending the stop prompt information to the electronic screen.

In some embodiments, the real-time position information of the weighing vehicle may be data reported by a positioning system of the weighing vehicle itself, or data reported by positioning devices arranged around the wagon balance.

In this embodiment, if the position deviation amount is greater than 0, it is indicated that the vehicle to be weighed is not driven into the weighing area, which may be the situation shown in fig. 3, and at this time, the parking prompt information may be parking prompt information such as "please drive forward x meters and get off" or "please drive backward x meters and get off" because the vehicle to be weighed is not driven into the weighing area completely.

If the position deviation amount is equal to 0, it indicates that the vehicle to be weighed has driven into the weighing area, and this situation may be due to the fact that the vehicle is pressed against the weight or there is foreign matter shielding, etc., so that the control device determines that the vehicle to be weighed is not located in the weighing area, and the stop prompt information may be abnormal prompt information such as "please remove foreign matter pressing against the weight interference" or "please drive the vehicle away from the ground".

In practical application, the electronic screen can be arranged on at least one side of the wagon balance and at the position which is convenient for a driver to check, so that the driver can know the parking state of the vehicle to be detected in time.

In some embodiments, indicator lights may also be provided at both ends of the wagon balance. Specifically, the first indicator light can be arranged at the inlet of one end of the wagon balance, the second indicator light is arranged at the outlet of the wagon balance, and the control device is further connected with the first indicator light and the second indicator light.

In practical application, when the control equipment detects that the vehicle to be weighed has weighing authority, the first indicator lights are controlled to light green lights, and the second indicator lights are controlled to light red lights, so that a driver can be reminded to drive in the wagon balance. When the control equipment detects that the weighing process is abnormal and a weighing result is obtained, the second indicator light is controlled to light a green light, and the first indicator light is controlled to light a red light, so that a driver can be reminded of ending the weighing and driving away from the wagon balance.

In an embodiment, according to image information of a vehicle to be weighed uploaded by an image acquisition device, judging whether an abnormality exists in a weighing process of the vehicle to be weighed, including:

determining at least one key region from the image information;

extracting actual measurement image characteristics in each key area;

In this embodiment, in order to prevent cheating in the weighing process, image information of the weighing process may be collected by the image collecting device, so as to determine at least one key area from the image information. For example, the key area may be an area where cheating is likely to occur, such as a vehicle cab, a cabin, two sides of a wagon balance, and the like.

In practical application, the preset image features of each key region can be stored in a feature database in advance, in an abnormality detection link, the actually measured image features can be compared with the preset image features of the key region, and an abnormality judgment result is obtained according to the condition that feature comparison is consistent.

For example, no person or foreign matter enters the area where the carriage is located under normal conditions, the types of goods are consistent, if personnel or abnormal entry exists, or the types of goods in the carriage are inconsistent, at the moment, the actually measured image features corresponding to the area are different from the preset image features, the situation that feature comparison is inconsistent occurs, and therefore the weighing process can be judged to be abnormal.

In practical application, the image acquisition equipment can adopt a high-definition camera, and the acquired image information can be stored for reservation, so that the follow-up check is facilitated.

Through an abnormal judgment link, the cheating problem in the weighing process can be reduced to a certain extent, and the accuracy and the authenticity of the weighing result can be improved.

In an embodiment, the control device is further connected to a loading and unloading management terminal, and the wagon balance weighing method may further include:

the method comprises the steps of transferring the corresponding cargo loading amount of the vehicle to be weighed stored in the cargo loading and unloading management terminal;

the weight deviation is determined based on the weight of the cargo and the amount of the cargo.

In this embodiment, the control device may further be connected to the loading and unloading management terminal, and after the control device calculates the weight of the cargo, the control device may call the loading amount corresponding to the vehicle to be weighed from the loading and unloading management terminal, so as to make a difference between the weight of the cargo and the loading amount, and obtain a weight deviation.

Through the calculation of the weight deviation, the weight deviation between the goods actually weighed by the vehicle to be weighed and the goods loaded can be known, if the weight deviation is within a reasonable range, the weighing process is normal, and if the weight deviation exceeds the reasonable range, the problem that the goods are poured or hidden privately can be solved.

In an embodiment, the control device is further connected to a supervisory terminal, and after determining the weight deviation, the wagon balance weighing method may further include:
