Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless electronic sling scale auxiliary devices, in particular to a device applied to wharf weighing scenes, which can effectively prevent weighing data from being misstored. BACKGROUND

[0002] In the daily operation of the wharf, wireless electronic sling scales are widely used in the weighing work of goods. However, the existing wireless electronic sling scales have many problems in the data storage link. The wharf environment is complex, and the personnel operate frequently, which can easily lead to misoperation and cause weighing data to be stored incorrectly. For example, data storage is performed when the goods are not stable, or repeated measurement is performed during the clearing process and is stored incorrectly. These misstored data can seriously affect the accuracy of the wharf goods measurement, and further cause subsequent cargo settlement disputes, inventory management confusion and other problems, which brings great inconvenience and economic losses to the wharf operation.

The weighing sensor is used to accurately detect the weight supported by the sling scale, and the position sensor is responsible for real-time monitoring of the change of the suspension position of the sling scale. Through these sensors, the working state data of the sling scale can be comprehensively collected.

[0006] o Data processing module: connected with the sensor module, receives the data transmitted by the weighing sensor and performs in-depth analysis. Determine whether the sling scale is in a normal weighing state. If it is determined to be normal, output an allowed storage signal; otherwise, output a prohibited storage signal.

[0007] o Storage control module: connected with the data processing module, controls the storage operation of the weighing data according to the signal output by the data processing module. When the allowed storage signal is received, the weighing data is allowed to be stored in the storage device; when the prohibited storage signal is received, the weighing data is prevented from being stored in the storage device.

[0008] o Communication verification module: in the wireless communication process between the wireless electronic sling scale and the data receiving terminal, the transmitted data is encrypted and additional check code processing is performed. The data receiving terminal verifies the check code of the received data, and only when the check code is correct and the data format meets the regulations, the data is allowed to be stored in the storage device.

[0009] o Operation record unit: set in the storage control module, used for detailed recording of each weighing operation and data storage attempt related information, including time, weighing data, operation status, etc., for subsequent tracing and problem troubleshooting.

[0010] o Anti-misoperation mechanism: the storage control module sets a special anti-misoperation mechanism for storage operation, for example, when receiving a storage operation instruction, only when receiving a position sensor trigger signal and other specific operation conditions, the storage operation is executed.

[0011] o Data verification unit: the data processing module sets a data verification unit to verify the legality and rationality of the weighing data to be stored, such as judging whether the data is within the preset weight range, if it exceeds the range, output the prohibition storage signal.

[0012] o Storage device and connection method: the storage device can be a local database or a cloud storage server, the storage control module is connected with the storage device through wired or wireless communication mode to realize reliable storage of data.

[0013] The position sensor is a photoelectric sensor or a proximity sensor, which triggers a signal by sensing the position of the suspension scale.

[0018] Figure 1 is a schematic diagram of the overall structure of the wireless electronic suspension scale wharf weighing prevention repeated storage device, wherein 1 is a wireless electronic suspension scale, 11 is a weighing sensor, 12 is a position sensor; 2 is an AD data processing module; 3 is a storage control module; 4 is a wireless communication transmitting module; 5 is a wireless communication receiving module; 6 is a weighing data processing module. DETAILED DESCRIPTION

[0019] 1. Sensor module installation and data acquisition: the weighing sensor 11 is installed at the key position of the hoist scale 1 under pressure, which can ensure accurate detection of the weight of the hoist scale. The position sensor is installed below the suspension of the hoist scale 1, which can monitor the change of the suspension position in real time. The data collected by each sensor is transmitted to the AD data processing module in real time.

[0020] 2. Workflow of data processing module: the AD data processing module receives the data from the weighing sensor and the position sensor, first preprocesses the data to remove noise interference. Then, according to the preset normal working state threshold, such as weight range, position allowed deviation, etc., it is judged whether the hoist scale is in normal weighing state. If it is in normal state, the allowed storage signal is output; if it is abnormal, the prohibited storage signal is output. At the same time, the corresponding signal is output according to the result. The data verification unit verifies the legality and rationality of the weighing data to be stored, and outputs the signal according to the verification result.

[0021] 3. Operation of storage control module: the storage control module 3 receives the signal output by the weighing data processing module 6, and when it receives the allowed storage signal, it controls the weighing data to be stored in the storage device. When it receives the prohibited storage signal, it prevents the data from being stored, and records the operation state. When it receives the storage operation instruction, it judges whether the specific operation condition is met, and if it is met, it executes the storage operation, otherwise it does not execute.

[0022] 4. Work of wireless communication module: in the process of wireless communication, the wireless communication transmission module 4 encrypts and adds check code to the data sent by the hoist scale 1 and the position sensor 12, and the wireless communication receiving module 5 receives the data, verifies the check code according to the preset algorithm, and only when the check code is correct and the data format meets the regulations, the data is allowed to be stored in the storage device.

[0023] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
