In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in other sequences than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a schematic structural diagram of a weight verification system according to an embodiment of the present invention, where the system includes: a controller 120, a first driving carriage 110 for loading the weight to be checked, a mass comparator 130, and a dual guide, wherein,
the controller is used for sending a first driving instruction to the first driving trolley, receiving the actual weight of the current weight to be checked sent by the mass comparator, and checking the weight to be checked according to the actual weight;
the first driving trolley is used for moving to the position of the mass comparator from a first initial position along the double guide rails after receiving a first driving instruction, and placing the weight to be checked in the mass comparator;
the mass comparator is used for acquiring the actual weight of the weight to be checked and transmitting the actual weight to the controller.
When the weight is checked, tools such as a crane and a forklift are generally used, and when the weight is placed on the mass comparator by using the tools, the mass comparator is impacted, so that the mass comparator is easily damaged.
As shown in fig. 1, the controller 120 may be in wireless or wired communication with the mass comparator 130 and the first driven cart 110, respectively, for interaction.
Referring to the schematic diagram of the position relationship of the weight calibration system in fig. 2, the first driving trolley 2 for loading the weight to be calibrated can be controlled by the controller, so that the weight to be calibrated can be automatically moved and placed, and the influence caused by uncontrollable factors is reduced. As shown in fig. 2, the first driving carriage 2 is loaded with the weight 3 to be checked, and can move on the double guide rails 4 when controlled by the controller to move.
The mass comparator 1 can send the actual weight to the controller after determining the actual weight of the weight to be checked, and the controller checks according to the actual weight, specifically, when checking, the controller can obtain the mass nominal value of the weight to be checked, then calculate the deviation value between the actual weight and the mass nominal value, and if the deviation value is within the acceptable range, the check is considered to be passed. The definition of nominal value is a suitable approximation for marking or identifying an element, device or apparatus. Here, the mass nominal value is information carried at the time of shipment of the weight, and indicates an appropriate approximate value of the mass of the weight. The verification of the weight is in fact a verification between the actual weight and the nominal value of the mass.
In one embodiment, the system further comprises: a second driving trolley for loading standard weights,
the second driving trolley is used for moving to the position of the mass comparator from a second initial position along the double guide rails after receiving a second driving instruction sent by the controller, and placing the standard weight on the mass comparator;
the controller is also used for obtaining the weight of the standard weight from the mass comparator as the check weight, comparing the check weight with the actual weight of the weight to be checked, and checking the weight to be checked according to the comparison result.
Because the quality comparator 1 is similar to a high-precision electronic platform scale, the weight of the standard weight and the weight to be checked can be measured, and then the controller is used for completing the check of the weight to be checked through the comparison between the standard weight and the weight to be checked.
Referring to the schematic structural diagram of the weight verification system with the standard weight in fig. 3, the second driving carriage 5 is loaded with the standard weight 6 and can move on the double guide rails 4 when controlled by the controller to move. The mass comparator 1 is placed between the first driving trolley 2 and the second driving trolley 5, and it should be noted that the mass comparator may be placed in the gap between the two rails of the dual rail 4 without contacting the rails.
The standard weight can be determined according to the weight to be checked, and the mass nominal value of the standard weight should be the same as that of the weight to be checked. The controller can obtain the weight of standard weight from the quality comparator, as check-up weight, and compare check-up weight and the actual weight of waiting to check-up weight, when comparing, can be the deviation value of calculating between waiting to check-up weight and the standard weight, it is specific, can be the difference of calculating check-up weight and actual weight, divide the difference by 2 again, regard the quotient that obtains as the deviation value, at last through comparing the deviation value with the acceptable range that sets for in advance, if the deviation value falls into acceptable range, then can regard as waiting to check up the weight check and pass.
In another implementation, the controller may further control the first driving trolley 2 and the second driving trolley 5 respectively, so that the first driving trolley 2 and the second driving trolley 5 place the weight 3 to be checked and the standard weight 6 in the mass comparator 1 for multiple times to obtain multiple weighing results, it should be noted that, for reasonable application of the obtained weighing results in subsequent checking, the times of placing the weight to be checked and the standard weight in the mass comparator should be the same, and the same number of check weights and the same number of actual weights are obtained. After obtaining a plurality of check weights and a plurality of actual weights with the same number, when the controller judges that the weight to be checked is checked according to the comparison result, the controller can calculate an average value according to all weighing results obtained by measuring the weight to be checked for a plurality of times, calculate an average value according to all weighing results obtained by measuring the standard weight for a plurality of times, perform subtraction calculation on the average values obtained by the two times, divide the obtained difference value by the number of times of measuring the weight to be checked, use the obtained quotient as a deviation value, and determine whether the weight to be checked passes the check according to the deviation value and a preset acceptable range.
In one embodiment, the controller is further configured to:
before sending a first driving instruction to a first driving trolley, acquiring weight information of a weight to be checked loaded on the first driving trolley, and matching the weight information in a preset weight database;
if the matching is successful, a first driving instruction is sent to the first driving trolley;
and if the matching fails, newly adding a data record corresponding to the weight information in the weight database.
Before the first driving trolley 2 is driven to move towards the mass comparator 1 and the weight of the weight to be checked loaded on the first driving trolley 2 is checked, in order to avoid the situation that the weight to be checked is misplaced, the weight loaded on the first driving trolley 2 needs to be checked, and whether the weight belongs to the weight to be checked in the checking plan or not is determined.
The weight information corresponding to the current weight can be determined in a mode of manually inputting the weight information, and the weight information comprises identity information capable of indicating the weight, such as the code of the weight, and information such as verification date and verification validity period can also be included. After the weight information is obtained, the weight information can be matched in a preset weight database, if the matching is successful, namely data matched with the weight information exist in the weight database, the weight is proved to be a weight in a verification plan, a first driving instruction is sent to a first driving trolley, and the verification of the weight to be verified is started.
If the matching fails, namely data matched with the weight information does not exist in the weight database, the weight is proved to belong to a brand new weight in the weight database, a data record corresponding to the weight information can be newly added in the weight database, for example, a weight number is allocated to the weight according to a coding rule, blank information is configured in other data, and after the number is allocated and the verification is completed, the newly added data record can be perfected, for example, the verification date, the verification validity period and other information are perfected.
In one embodiment, the system also comprises a weight identification module and a monitoring module,
the monitoring module is used for monitoring whether weights exist in the first driving trolley or not, and if the weights exist, a checking request is sent to the controller;
the controller is also used for sending an identification instruction to the weight identification module when receiving the checking request;
the weight identification module is used for detecting whether weight information exists on a weight in the first driving trolley when an identification instruction is received, acquiring the weight information and sending the weight information to the controller if the weight information is detected, and sending a distribution request to the controller if the weight information is not detected;
the controller is also used for matching weight information in a preset weight database when the weight information is received, and sending a first driving instruction to the first driving trolley if the matching is successful;
the controller is also used for distributing weight information for the weights to be checked when receiving the distribution request, newly adding a data record corresponding to the weight information in the weight database, and marking the weight information on the weights to be checked.
Specifically, the monitoring module may be a weight sensor that is present on the first driving carriage, and when sensing that the weight is present on the first driving carriage, the monitoring module determines that the weight is present, and sends a check request to the controller. In another implementation, the monitoring module can also be a camera, the camera can acquire a picture of the first driving trolley, when the picture of the first driving trolley on which the weight is placed is acquired, the weight is considered to be monitored, and a checking request is sent to the controller.
And after receiving the checking request from the monitoring module, the controller sends an identification instruction to the weight identification module so as to acquire weight information corresponding to the weight. The weight identification module can be a reader arranged on the first driving trolley and a label correspondingly arranged on the weight, when the weight with the label is loaded on the first driving trolley, the label enters a magnetic field, receives a radio frequency signal sent by the reader, and sends information stored in the label by virtue of energy obtained by induction current.
In another realization, can dispose two-dimensional code or bar code on the weight, weight identification module can be the camera, and when monitoring module also was the camera, monitoring module and weight identification module can be same camera. When the camera receives the identification instruction, can sweep the sign indicating number to the two-dimensional code or the bar code that mark on the weight body, can acquire the weight information that contains in two-dimensional code or the bar code after sweeping the sign indicating number to in sending the weight information to the controller.
If the weight information is not detected, the weight identification module can send a distribution request to the controller, when the distribution request is received by the controller, the weight information is distributed for the weights to be checked, data records corresponding to the weight information are newly added in the weight database, and the weight information is marked on the weights to be checked. In a concrete realization, when the weight information is marked on the weight to be checked, the code spraying machine can be controlled to spray the two-dimensional code or the bar code and the like containing the weight information onto the weight without the weight information before through the configuration of the code spraying machine.
In one embodiment, the system further comprises an environmental control module, a circulating water pump, a semiconductor thermopile, and a temperature sensor;
the temperature sensor is used for acquiring the real-time temperature of the current checking environment and sending the real-time temperature to the environment control module;
the environment control module is used for judging whether the received real-time temperature meets the check condition or not, if so, sending a signal that the current temperature meets the check condition to the controller, and if not, determining the temperature difference between the real-time temperature and the temperature required in the check condition, and determining the water flow speed of the circulating water pump and the current value applied to the semiconductor thermopile according to the temperature difference;
the semiconductor thermopile is used for adjusting the degree of refrigeration and heating according to the value of the current passing through;
the circulating water pump is used for adjusting the heat exchange speed between the inside of the checking environment and the outside of the checking environment through the internal water flow speed.
In the weight verification process, the attributes such as the accuracy grade and the specification of the weight to be verified determine the verification conditions, and different and adaptive verification conditions can be provided for different weights to be verified. In order to ensure that the process of checking the weight is finished in a space meeting the checking condition, the constant-temperature and constant-humidity box can be used as a checking environment, and the temperature and the humidity in the constant-temperature and constant-humidity box are constant. Temperature, humidity, air current etc. all can influence the precision of weight check, and the existence of air current is mainly because the device production of regulation and control temperature, when in order to let the check-up environment regulate and control to the temperature that satisfies the check-up condition from current ambient temperature, can carry out the regulation and control of temperature jointly through circulating water pump and semiconductor thermopile.
In one specific implementation, the mass comparator can be placed in a constant temperature and humidity chamber to ensure that the mass comparator obtains the weight of the weight under the verification environment meeting the verification conditions. Referring to the schematic structural diagram of a constant temperature and humidity cabinet of fig. 4, a housing of the constant temperature and humidity cabinet 7 may be configured with a heat dissipation fan 8, and when the temperature is controlled, the heat exchange is performed between the inside and the outside of the constant temperature and humidity cabinet 7, so that the heat can be dissipated outside the constant temperature and humidity cabinet 7 through a heat conductive aluminum block, and meanwhile, the heat dissipation speed can be increased by configuring the heat dissipation fan 8 for the heat conductive aluminum block. The circulating water pump, the semiconductor thermopile and the temperature sensor are all arranged inside the constant temperature and humidity box 7, and the environment control module controls the degree of refrigeration or heating and the degree of refrigeration and heating by controlling the current value applied to the semiconductor thermopile and the internal water flow speed of the circulating water pump.

when the weight to be checked and the platform layer are placed on the mass comparator, the hydraulic lifting device is controlled to descend to a first designated height separated from the platform layer, and the weight to be checked and the platform layer are placed on the mass comparator;
when taking away from the quality comparator with waiting check-up weight and platform layer, control hydraulic pressure elevating gear rises, jack-up the platform layer to the second designated height to make platform layer and quality comparator separate completely.
Referring to fig. 5, a schematic side view of a weight checking system with a hydraulic lifting device is shown, in which the first driving carriage 2 includes a hydraulic lifting device 7 and a platform layer 9, and the second driving carriage 5 includes a hydraulic lifting device 8 and a platform layer 10. Hydraulic pressure elevating gear and platform layer can be separated, when the drive dolly is placed the weight in the quality comparator, can place together with the platform layer. In particular implementations, the platform layer may be a weight of known mass nominal value.
Referring to fig. 6, a top view of a weight checking system with a hydraulic lifting device, as can be seen from fig. 6, when the first driving carriage 2 moves to the position of the mass comparator 1, the hydraulic lifting device 7 can cross over the mass comparator 1, and the platform layer 9 is placed on the hydraulic lifting device 7, the initial height of the hydraulic lifting device 7 needs to be higher than the height of the mass comparator 1, so as to ensure that the platform layer 9 can be located right above the mass comparator 1 when the first driving carriage 2 moves to the position of the mass comparator 1.
In the process of placing the weight 3 to be checked and the platform layer 9 on the mass comparator, when the first driving trolley 2 moves to the position of the mass comparator 1 and the hydraulic lifting device 7 crosses the mass comparator 1, when the hydraulic lifting device 7 descends to be level with the height of the mass comparator 1, the platform layer 9 can start to be in contact with the mass comparator 1, when the hydraulic lifting device 7 continues to descend, the platform layer 9 can be completely pressed on the mass comparator 1 together with the weight 3 to be checked, and when the hydraulic lifting device 7 descends to be at a first designated height completely separated from the platform layer 9, the descending action can be stopped.
In the process of taking away the weight 3 to be checked and the platform layer 9 from the quality comparator 1, the hydraulic lifting device 7 is controlled to ascend, when the hydraulic lifting device 7 ascends to be level with the height of the quality comparator 1, the hydraulic lifting device 7 can start to have a contact relation with the platform layer 9, when the hydraulic lifting device 7 continuously ascends, the hydraulic lifting device 7 can jack the platform layer 9, the platform layer 9 is completely separated from the quality comparator 1, when the hydraulic lifting device 7 ascends to a second designated height, and after the platform layer 9 is completely separated from the quality comparator 1, the hydraulic lifting device 7 can stop ascending and return to a first initial position.
The process of placing the weight to be checked into the mass comparator by the first driving trolley and the process of taking the weight away from the mass comparator are the same as the principle of the second driving trolley, and repeated description is omitted.
In another kind of realization, in the same time weight check-up process, because first drive carriage 2 and second drive carriage 5 can be controlled by the controller, respectively with platform layer 9 and wait to check up weight 3 many times, and platform layer 10 and standard weight 6 prevent with the quality comparator 1 on obtain a plurality of weighing results, consequently, when obtaining weighing result after the drive carriage is placed at every turn and then retrieving, this operation can be repeated, until the weighing result number of times that obtains satisfies preset number of times, just return to initial position.
When the check weights to be checked are checked through calculation, the weighing results of all the platform layers 9 and the check weights 3 can be subtracted from the weighing results of all the platform layers 10 and the standard weights 6, and then the obtained difference is divided by the weighing times. Illustratively, when the first driving trolley 2 places the platform layer 9 and the weight 3 to be checked on the mass comparator 1 twice, two weighing results are obtained, I B1 And I B2 . Similarly, the first driving trolley 5 places the platform layer 10 and the standard weight 6 on the mass comparator 1 twice to obtain two weighing results, I A1 And I A2 . At this time, the calculation process of the deviation value delta I of the weight to be checked and the standard weight is as follows:
after calculating the delta I, the controller compares the delta I with a preset acceptable range, if the delta I is within the acceptable range, the verification is considered to be passed, and if not, the verification is considered not to be passed.
After confirming whether the check of the weight to be checked passes, partial information can be updated in the data record corresponding to the weight information of the weight to be checked, and the check date can be updated exemplarily. And if the verification passes, updating the verification effective date according to the verification effective time length of the weight, for example, if the verification effective time length is one year, updating the verification effective date to the date from the current date to the date after one year. Correspondingly, if the verification fails, the verification effective date is not updated, and the label which fails to pass the verification can be marked.
When determining whether the driving trolley is in place, a distance measuring sensor, such as an infrared sensor, can be used for realizing the purpose. In another implementation, referring to a schematic diagram of fig. 7 for determining the in-place condition of the driving trolley, hall switches are installed at the middle positions and proper positions of two sides of the dual-guide rails on two sides of the central axis of the mass comparator, and magnetic steel is installed at the corresponding middle position of the driving trolley.

For example, when the in-position signal from the hall switch 13 is received, it is determined that the second driving carriage 5 has reached the second initial position, and a command to stop the movement is sent to the second driving carriage 5.
