Description

Technical Field

[0001] The invention belongs to the field of measurement technology, and specifically relates to a weighing instrument, and in particular to a weighing measurement system and a measuring method thereof. Background Art

[0002] In some factories, raw materials need to be proportioned. During the process, the data obtained from weighing each raw material needs to be encrypted to avoid leakage of the raw material formula. In the weighing process, since there are many sensors in the overall equipment system, the data detected by the sensors will be sent to the host computer through wireless communication. Multi-sensor wireless transmission is prone to interference and lacks encryption. The distance between the sensor detection position and the host computer is far. When transmitting weighing data and other detection data, long-distance wireless communication is prone to interference and lacks encryption, resulting in data delay or packet loss. At the same time, the simultaneous existence of different types of sensors requires many types of communication ports, which will cause data interference and affect data reception and transmission.

[0003] Therefore, due to the technical problem that data is difficult to transmit and needs to be encrypted during the weighing process, it is necessary to design a weighing measurement system and its measurement method.

[0004] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

If the waveform data packet recorded in the database is the same as the waveform data packet restored by the host computer at this time, the weighing sensor module is judged to be normal, otherwise the weighing sensor module is judged to be abnormal.

Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment.

On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0024] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] like Figure 1 and Figure 2 As shown, in at least one disclosed embodiment, a weighing measurement system is provided, comprising: a control module, a carrier platform 1, and a weighing sensor module 2 electrically connected to the control module; the weighing sensor module 2 can be arranged on a base 3 to facilitate the fixation of the weighing sensor module 2; the weighing sensor module 2 is arranged on the bottom surface of the carrier platform 1, the carrier platform 1 is suitable for carrying materials (raw materials, etc.), and the weighing sensor module 2 is suitable for collecting waveform data corresponding to the materials carried on the carrier platform 1 during the weighing process; the waveform is similar to a sine wave; the control module is configured to judge the waveform data packet composed of the waveform data, and compress and encrypt the waveform data packet, and the control module sends the compressed and encrypted waveform data packet to the upper computer through the communication module, thereby realizing the compression of the collected waveform data, facilitating the transmission of data to avoid interference during the transmission process, and encrypting the waveform data to avoid leakage of the collected data.

[0026] In an optional embodiment, the control module judges the waveform data packet composed of the waveform data, that is, the weighing sensor module 2 packages the waveform data within a preset time to form a waveform data packet, and the control module is configured to judge whether the waveform data packet contains at least two cycles of waveform data. If it contains at least two cycles of waveform data, the control module compresses and encrypts the waveform data packet and sends it to the host computer. If the number of waveform data cycles in the waveform data packet is less than two, the parameters of the weighing sensor module 2 are adjusted so that the waveform data cycle within the preset time is greater than or equal to two cycles; one cycle of waveform data can reflect one weighing of the material, and one weighing process can include multiple weighings. The weight of the material can be obtained based on the waveform data in one cycle. A waveform data packet contains at least two complete cycles of waveform data, which can facilitate subsequent judgment of whether the weighing is accurate; the parameters of the weighing sensor module 2 can be the time of the weighing cycle, etc.

[0027] In an optional embodiment, the control module compresses and encrypts the waveform data packet and sends it to the host computer, that is, the control module is configured to obtain the total cycle time of all waveform data in the waveform data packet, and the number of cycles of the waveform data, arrange the values ​​corresponding to the total cycle time and the number of cycles in sequence, use the arranged character string as the encryption string of the waveform data packet, and compress and encrypt the waveform data in the waveform data packet; for example, there are two cycles of waveform data in a waveform data packet, and the total cycle time of the two cycles of waveform data is 2s, then the values ​​corresponding to the total cycle time and the number of cycles are arranged in sequence as 22, or the values ​​of the total cycle time and the number of cycles can be converted into binary respectively and then arranged in sequence, and the sequence arrangement is 1010. The encrypted string can be combined with the waveform data compressed subsequently to encrypt the data to avoid leakage during transmission, and the encryption effect can be further increased by converting the original values ​​corresponding to the total cycle time and the number of cycles into binary again.

[0028] like Figure 3 , Figure 4 and Figure 5As shown, in an optional embodiment, the control module compresses and encrypts the waveform data in the waveform data packet, that is, the control module is configured to compress the length of the waveform data in the horizontal axis direction by a first preset ratio, and compress the height of the waveform data in the vertical axis direction by a second preset ratio; and the compressed and encrypted waveform data and the encryption string together constitute a new waveform data packet, and the control module sends the new waveform data packet to the host computer through the communication module; the horizontal axis of the waveform data is time, and the vertical axis is the voltage value. After the waveform data collected by the weighing sensor module 2 is compressed by the first preset ratio and the second preset ratio, the data volume can be reduced, which is convenient for making the subsequent new waveform data packet smaller than the waveform data packet, facilitating data transmission and avoiding interference during transmission.

[0029] In an optional embodiment, the host computer is suitable for decrypting the new waveform data packet, that is, the host computer is configured to obtain the total cycle time and cycle number corresponding to the waveform data in the waveform data packet from the new waveform data packet according to the encryption string; and restore the waveform data in the new waveform data packet by the inverse of the first preset ratio and the inverse of the second preset ratio, and then obtain the total cycle time and cycle number of the restored waveform data; if the total cycle time and cycle number corresponding to the waveform data in the waveform data packet obtained from the new waveform data packet are the same as the total cycle time and cycle number of the restored waveform data, then the new waveform data packet is marked as not tampered with; the inverse of the first preset ratio and the inverse of the second preset ratio are pre-stored in the host computer, and after the host computer obtains the new waveform data packet, the total cycle time and cycle number corresponding to the waveform data in the corresponding waveform data packet are first read according to the encryption string, and then the waveform data is restored according to the inverse of the first preset ratio and the inverse of the second preset ratio, and the total cycle time and cycle number corresponding to the waveform data at this time are obtained after restoration, so as to facilitate the judgment of whether the compressed waveform data in the new waveform data packet has been tampered with, and to facilitate the accurate and precise acquisition of the weight of the material according to the restored waveform data.

[0030] In an optional embodiment, the host computer is configured to determine whether the waveform data corresponding to each period in a new waveform data packet is consistent after determining that the new waveform data packet has not been tampered with. If they are consistent, the weight data of the material is obtained according to the waveform data. If they are inconsistent, a detection instruction is sent to the control module. The control module is configured to control the weighing sensor module 2 again to collect the waveform data corresponding to the material carried on the load platform 1 during the weighing process; in an actual production environment, the material placed on the weighing platform is a whole package of material, which can be automatically grabbed and placed on the weighing platform by a robot or other device. Therefore, when the weighing sensor module 2 obtains the first waveform data, the material is still grabbed by the robot and is not completely placed on the weighing platform, resulting in the waveform data being unable to accurately reflect the material Therefore, the host computer will determine whether the waveform data corresponding to each period in the new waveform data packet are consistent after the new waveform data packet is restored, that is, whether the waveforms of each period are consistent. If they are consistent, it is determined that the waveform data restored in the new waveform data packet can accurately and precisely reflect the weight of the material. Otherwise, it is determined that the waveform data restored in the new waveform data packet contains waveform data affected by devices such as manipulators. At this time, the host computer sends a detection instruction to the control module, and the control module controls the weighing sensor module 2 to control the weighing sensor module 2 again to collect the waveform data corresponding to the material carried on the load platform 1 during the weighing process, that is, the weighing sensor module 2 collects and constructs a new waveform data packet, and then compresses and encrypts it and sends it to the host computer, which performs subsequent processing through the host computer to obtain the accurate weight of the material.

[0031] In an optional embodiment, a shooting device is provided on one side of the support platform 1, and the shooting device is suitable for shooting images of materials on the weighing platform and sending the images to the host computer; the host computer is also configured to build a database, and record the images corresponding to the materials, the parameters of the weighing sensor module 2, and the waveform data packets as a group of data for storage; the shooting device can directly use a camera, etc., which can integrate a wireless communication module to send the collected images to the host computer for storage; in the process of raw material proportioning, multiple batches of raw materials of different types and specifications will be weighed, and each type and specification of raw materials can be stored in a library to store materials and their corresponding images, weighing sensor module 2 parameters, and waveform data packets in the database.

[0032] In an optional embodiment, when the type or specification of the material changes, the camera captures an image of the material when the material is placed on the weighing platform, and the host computer is configured to match whether there is a material of the same type and specification in the database. If so, the corresponding weighing sensor module 2 parameters are retrieved from the database, and the weighing sensor module 2 parameters are sent to the control module. The control module is configured to adjust the weighing sensor module 2 according to the acquired weighing sensor module 2 parameters; in the batch weighing process, materials of the same type and specification do not need to frequently adjust the weighing sensor module 2 parameters, and the recorded weighing sensor module 2 parameters can be directly retrieved from the database.

[0033] In an optional embodiment, when the host computer determines based on the image that the material on the weighing platform at this time has the same type and specification of material stored in the database, the host computer is configured to restore the new waveform data packet obtained at this time, obtain the waveform data packet corresponding to the material at this time, and the host computer obtains the recorded waveform data packet from the database. If the waveform data packet recorded in the database is the same as the waveform data packet restored by the host computer at this time, it is judged that the weighing sensor module 2 is normal, otherwise it is judged that the weighing sensor module 2 is abnormal; the precision or accuracy of the weighing sensor module 2 will be abnormal after long-term use. Therefore, during the weighing process, when it is judged that the material weighed at this time has been recorded with the same type and specification in the database, after the host computer obtains the weight of the material at this time, it obtains the weight recorded in its historical record according to the waveform data packet stored in the database. If the two weights are the same, it is judged that the precision of the weighing sensor module 2 is accurate, otherwise it is judged that the weighing sensor module 2 is abnormal, and an alarm is issued at this time to remind the staff to come to the scene to repair or replace the weighing sensor module 2; the host computer can compare the waveform data packet of the material at this time with the waveform data packet in its historical data stored in the database, or compare according to the weight corresponding to the waveform data packet, to determine whether the precision of the weighing sensor module 2 is accurate.

[0034] At least one other disclosed embodiment also provides a measurement method using the above-mentioned weighing measurement system, including: the control module is configured to judge the waveform data packet composed of waveform data, and compress and encrypt the waveform data packet, and the control module sends the compressed and encrypted waveform data packet to the host computer through the communication module.

[0035] In summary, the weighing measurement system includes: a control module, a load-bearing platform 1, and a weighing sensor module 2 electrically connected to the control module; the weighing sensor module 2 is arranged on the bottom surface of the load-bearing platform 1, the load-bearing platform 1 is suitable for carrying materials, and the weighing sensor module 2 is suitable for collecting waveform data corresponding to the materials carried on the load-bearing platform 1 during the weighing process; the control module is configured to judge the waveform data packet composed of the waveform data, and compress and encrypt the waveform data packet, and the control module sends the compressed and encrypted waveform data packet to the host computer through the communication module, thereby realizing the compression of the collected waveform data, facilitating the transmission of data to avoid interference during the transmission process, and encrypting the waveform data to avoid leakage of the collected data.
