Description

Technical Field

[0001] The utility model belongs to the field of aluminum processing, and particularly relates to a traveling crane weighing display device. Background Art

[0002] At present, during the process of lifting aluminum ingots by a traditional traveling crane, the recorder needs to rely on the weighing display device supporting the weighing scale to read the weight data. Since the aluminum ingots need to be lifted to a certain height, it is inconvenient to observe and record. Moreover, the recorder has to get close to the weighing scale to record the data, which poses a great safety hazard and requires manual recording, resulting in low recording efficiency. During this process, each weighing requires collecting the weighing scale and the weighing display device first. When the battery of the weighing display device is out of power, it must be used near a power source. This makes it impossible for the recorder to ensure whether the weighing process meets the requirements. In the case of multi-batch weighing, it is necessary to make multiple round trips to confirm the weighing weight of the weighing scale. In a workshop such as a milling machine where weighing is often required, each weighing takes about 5 minutes, and the working efficiency is low.

[0003] Therefore, there is an urgent need for a traveling crane weighing display device to make the operation more convenient and safe and improve the efficiency of the weighing operation. Summary of the Invention

[0007] Further, the communication module includes an RS232 serial port module, the controller includes a first MCU chip, and the first MCU chip and the wireless transmission unit are in serial communication through the RS232 serial port.

[0009] Further, the wireless transmission unit and the wireless receiving unit include one or more combinations of a WiFi module, a Bluetooth module, and an NB-IoT module.

[0028] The wireless receiving unit 4 is further communicatively connected to a host computer.
