Technical Field
The invention belongs to the technical field of gravity sensors, and particularly relates to an automatic gravity sensor deformation correction method for a gravity vending cabinet.
Background
The gravity sensor mainly comprises an elastic element and a resistance strain gauge, wherein the elastic element can deform to a certain extent when being subjected to deformation of weight for a long time, so that the gravity sensor needs to be calibrated again under the influence of gravity for a long time. However, the gravity vending machine is periodically recalibrated during operation, which costs a lot of manpower and material resources and also causes the operation of the gravity vending machine to be interrupted. And the merchant does not have the standard weights needing to be calibrated, so that the automatic correction deformation of the gravity sales counter needs to be considered.
In the operation of the gravity vending cabinet, except the processes of replenishment and commodity selling, the commodities of each goods channel are fixed in the rest time, and the actual weight cannot be changed. The weighing value may vary, mainly due to temperature and deformation of the elastic element. The deformation of the gravity sensor only increases the test weight, the speed of the change is very slow, no influence is caused in a short time, but the operation of the gravity vending cabinet is long, so the deformation can occur after a long time. A long-term deformation monitoring mechanism needs to be established in a gravity sales counter, and when the deformation reaches a certain deformation degree, the automatic correction and repair function is carried out.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples.
A gravity sensor deformation automatic correction method of a gravity vending cabinet comprises the following steps:
setting a configuration format of a Flash medium:
the Flash data reading and storing aim is to open a space in the program storage area of the singlechip specially for storing the parameters and data to be memorized by the system, thereby completely replacing EEROM and achieving the aims of reducing cost and keeping data secret. The implementation method mainly comprises four parts: reading Flash data, setting the Flash data, storing the Flash data and erasing a Flash space. The data reading and storing method needs to be determined according to the configuration format of the data.
Here is defined as follows:
1, alternately storing the latest records by using 2 blocks according to the characteristics of Flash and the data required to be stored by the gravity sales counter;
2, the size of each Block is 4K (4096B), the length of each record is fixed and is determined according to the number of lanes of the gravity sales counter;
3, when the first Block is full, erasing another Block, and storing the newly erased Block from the first record, wherein the record storage of each Block is sequentially stored;
and 4, when the current record is stored in the Block, searching an empty position behind the position stored last time for storing, and if the space of the empty position is insufficient and the storage cannot be carried out, switching to another Block for storing.
The gravity sensor automatically corrects the deformation:
1, monitoring the weight of each goods channel in real time, and then regularly storing the current information in a Block of a Flash medium of a single chip microcomputer of the gravity vending cabinet.
The timed interval cannot be too short or too long, and if the time interval is too short, the total weight information recorded is limited, and it may not be possible to determine the lane deformation, and if the time interval is too long, the detected deformation may be abrupt, thus not distinguishing whether the deformation is caused by an abrupt change in the lane cargo.
In this embodiment, the time interval is controlled to be once in 12 hours, 2 times of detection are performed every day, and 60 lanes are supported by one container, so that one Block (4096B) of Flash can store data amount for 8 days, and 2 blocks are used for switching, thereby reducing the erasing action of Flash and ensuring the lane change condition for at least 8 days. Therefore, the change condition of each goods channel can be effectively detected and then automatically corrected.
And 2, reading all the stored records, extracting the information of the cargo track record needing to be corrected, sequentially comparing whether mutation exists, and if the mutation exists, analyzing data behind the mutation point by taking the mutation point as a boundary. If the records are continuous and have slight changes, automatic correction can be carried out, the difference of deformation is obtained by subtracting the foremost weight from the last recorded weight, and then the difference is divided by the current weight, so that the coefficient of automatic correction is obtained, namely the deformation coefficient of the cargo way = K (after weight change-before weight change)/after weight change;
the correction of the cargo way gravity sensor is to analyze the continuous records of the recently stored same cargo way, the current weight in the records should be no sudden change, only slow and slight change, but the total change is increasing, so that the cargo way can be judged to be deformed.
In this example, the absence of a snap-off phenomenon is defined as a difference in weight of no more than 10g among 2 consecutive records.
3, when calculating the current weight, the measured weight needs to be multiplied by the correction coefficient, so that a more accurate weight can be obtained.
4, in the step 2, the straightening is required to be performed from the first lane to the last lane in sequence, so that all lanes are straightened.
In fig. 1, the measured current weight of each lane, and the parameters for automatic correction, are defined. The measured current weights and the auto-leveling parameters for all lanes of the entire gravity box are then tabulated as a cps table.
In FIG. 2, the parameters detected in FIG. 1 are stored in the flash in order. The monitoring times in fig. 2 are fixed time intervals in order to calculate the change in deformation.
FIG. 3 is a record of actual simulated deformation data, from the data of FIG. 3, it can be seen that lane 1 and lane 2 are both deformed and the detected weight is gradually increased; the cargo way 3 is not deformed, and the detected weight is basically fixed.
Other embodiments of the present invention than the preferred embodiments described above will be apparent to those skilled in the art from the present invention, and various changes and modifications can be made therein without departing from the spirit of the present invention as defined in the appended claims.
