Detailed Description
In order for those skilled in the art to understand the technical solutions disclosed in the present disclosure, the technical solutions of the various embodiments will be described below with reference to the embodiments and related drawings, where the described embodiments are some embodiments of the present disclosure, but not all embodiments. The terms "first," "second," and the like, as used in this disclosure, are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, "including" and "having" and any variations thereof are intended to cover and not be exclusive inclusion. For example, a process, or method, or system, or article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, system, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present disclosure. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those skilled in the art will appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, fig. 1 is a method for calibrating a smart scale according to one embodiment of the present disclosure, including the steps of:
s100, after an operator finishes the latest calibration on one side of the intelligent scale according to the indication of the first application, the intelligent scale automatically sends the latest calibration parameters to a server through the first application, wherein the parameters comprise the parameters of linear calibration;
s200, the server verifies the validity of the first application;
s300, when the first application passes verification of validity, the server searches parameters which are stored at one side of the server and are calibrated for the last time;
s400, comparing the searched parameter of the last calibration stored at one side of the server with the parameter of the last calibration sent at the present time, and marking the present calibration as an abnormal state if the parameter exceeds a normal error range.
Through the technical scheme:
on the one hand, after the intelligent scale finishes calibration, the intelligent scale can send calibration parameters to the server as long as the first application passes verification of the server; it will be appreciated that the parameters include parameters for linear calibration, in some cases parameters for span calibration, and in other cases parameters for nonlinear calibration, depending on the linear and nonlinear characteristics of the sensor of the scale. The present disclosure does not attempt to address any of the scale sensors, and therefore, regarding the calibrated parameters, they are not described in detail herein in view of the prior art. For ease of understanding, the linear calibration may include two cases, one being a linear equation like y=k×x and the other being a linear equation like y=k×x+b. As for the nonlinear calibration, a quadratic function may be involved.
On the other hand, since the validity of the first application will be verified by the server here, the present disclosure can enhance security in the information transmission process by means of the first application.
It should be noted that, the server disclosed in the disclosure may be a server which belongs to a different product from the intelligent scale, that is, a server in a traditional sense, or may be integrated in the intelligent scale; when the server is integrated in the smart scale, the server is a virtual server, which corresponds to a part of the smart scale, and may be understood as a functional unit, as long as the virtual server and the functional unit can satisfy the above-mentioned embodiments and other embodiments of the present disclosure. That is, the server referred to in this disclosure may be a server in a conventional sense, or may be local to the smart scale. When a server is located at a remote or cloud end, the corresponding server is referred to as a remote/remote server, or cloud end server.
Since the intelligent balance belongs to a weighing apparatus, whether the measurement is accurate or not is involved, the inventor also verifies the validity of the first application through the server in the above embodiment. Of course, the legitimacy of the first application may not be verified if the security is not to be reduced or the patent is to be maliciously circumvented. At this time, even if the validity of the first application is not verified by the server, it should be considered in the scope of protection of the present application. Further, the server of the present disclosure also has the ability to not verify the legitimacy of the first application.
More specifically, taking the linear calibration y=kx+b as an example, the constant k is obtained by zeroing (remark: to obtain the b value) and by providing a y value corresponding to the standard weight, which is a common calibration method for the load cell. For example, a weight having a standard weight of 200 g.
In a further embodiment of the present invention,
calibration parameters (e.g., k-value k in linear calibration) acquired at a time (e.g., when the smart balance is shipped from the factory and/or at a time of calibration) 0 ) Stored in registers of the cloud and/or the intelligent scale. Preferably, the calibration parameters stored at this time are usually default values/initial values at the factory, or are stored by a third party (e.g. supervisorConstruct) default/initial values that are obtained and saved by an application.
In another embodiment, in step S100:
the last calibration can be completed only by the operator according to the guidance of at most two virtual keys of the user interface, and no command consisting of more physical keys is required to be operated.
For this embodiment, if only one virtual key is set, e.g. "calibrate", the operator is guided to start calibration, but this may cause false triggers; if two virtual keys are set, the probability of false triggering can be reduced, for example, two keys can be set and calibrated. Compared with the prior art, the method adopts the physical keys and more than three physical keys, and the operator is guided to execute a complex command through the keys, and the method is essentially to execute a command instead of executing a menu function like the execution of the keys on the mobile phone to acquire the IMEI serial number.
Moreover, since the present disclosure verifies the first application, the smart use of the first application by the scheme of the present disclosure improves security that is not available when prior art scales are calibrated.
In another embodiment, in step S100:
when the last calibrated parameter is transmitted, the transmitted information also carries any one or any combination of the following: the first ID, the first key, and the first digital certificate.
It can be appreciated that this embodiment is intended to carry as much legal information as possible when transmitting information.
In another embodiment, step S200 includes:
the legitimacy of the first application is verified by the first ID, and/or the first key, and/or the first digital certificate.
It is apparent that the server of the present disclosure verifies the legitimacy of the first application using the first ID, and/or the first key, and/or the first digital certificate.
In a further embodiment of the present invention,
the first ID is a user ID or a device ID, for example, a MAC address of the smart scale.
In order to avoid additional input by the operator or user, the first ID may be a user ID that is pre-assigned to the smart scale when it is a user ID. At this time, in order to avoid additional input of an operator or a user, the user name and the device ID (e.g., the MAC address of the smart scale) may be further pre-bound to the server, so that the validity of the first application may be verified through the user name and the device ID.
It will be appreciated that, optimally, the process of verifying the legitimacy of the first application may be simplified as much as possible by simply the device ID, e.g. the MAC address of the smart scale. However, if the security is to be maximized, it is possible to verify not only the first ID but also the first key and/or the first digital certificate as described in the previous embodiments.
It can be appreciated that with the MAC address and the first key, two technical effects can be obtained even further in combination with the first digital certificate: first, the security level of the first application is improved, and the threshold of intrusion and imitation application is improved; secondly, the first application and the MAC address of the device are associated, so that personalized application distribution aiming at different devices can be realized, the application and the device are in binding relation, and theoretically, even if the MAC address is forged, the application on each intelligent scale is safe enough because the first secret key and/or the first digital certificate are difficult to forge.
It should be noted that, more preferably, the first key or the first digital certificate should have a correspondence with the MAC address of the device, so that the present disclosure may further enhance the security of the device and the application in an offline or online manner, specifically:
(1) For offline verification, when the first application runs on the intelligent balance device, the first key or the first digital certificate in the first application can be obtained, the corresponding MAC address is resolved, the resolved MAC address is compared with the 'device MAC address' read from the device hardware, and whether someone falsifies the MAC address is verified;
(2) For online verification, the "MAC address of the device" may be pre-stored (e.g., pre-stored at the factory) at a location outside of the device, such as a server, and then, by both the server and the smart scale device, verified and verified online: the "MAC address of the device" stored on the server is consistent with the "MAC address of the device" acquired by parsing the first key or the first digital certificate in the first application on the device side, which is that the "MAC address of the device" may be pre-stored outside the device, such as the server, and even the "association relationship" between the "MAC address of the device" and the "first key" (or the "first digital certificate") may be stored outside the device, such as the server, so that the online verification scheme is safer and is more difficult to tamper with and forge the first application or the smart scale device.
In a further embodiment of the present invention,
the first application includes an APK file or an EXE file or an MSI file or other operating system applicable application files.
It can be appreciated that this embodiment is a selection for the first application.
In another embodiment, the method further comprises the steps of:
s500, if the current positioning information and the MAC address of the intelligent scale are beyond the normal error range, the current positioning information and the MAC address of the intelligent scale are obtained and are transmitted to a third party together with the last calibrated parameter stored on one side of the server and the last calibrated parameter transmitted at the time.
It can be appreciated that when an unexpected error occurs beyond the normal error range, such as during the normal life cycle of the sensor, a third party needs to intervene in the maintenance and management of the intelligent balance, and even in the supervision and punishment.
As for the positioning information, the positioning information can be obtained through a preset GPS or Beidou positioning device in the intelligent scale.
For example, compared to a certain calibration parameter k as described above 0 After a certain period of time, recalibrate and acquire k 1 Value of k with last time 0 Value, compare, if k 1 Satisfy one ofConditioned (e.g., k 1 At k 0 ±k 0 A range of/a; of course, k can also be measured by adopting a way of strict confidence degree, confidence interval and the like in the aspect of statistics 1 ) Then represent k 1 And if the value is the trusted value, otherwise, carrying out cloud and/or local early warning flow.
In another embodiment, the server records the parameters of the past calibration each time the calibration is completed. In this way, the server can form a complete log whether the calibration is normal or abnormal. Even when an anomaly occurs, the server may attempt to forcedly update to the side of the smart scale with its stored last calibration parameters, attempt to repair the calibration process of the smart scale in order to attempt to find the cause of the failure, etc.
Steps in the methods of embodiments of the present disclosure may be sequentially adjusted, combined, and pruned as desired.
