Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the material platform load monitoring and alarming system comprises a plurality of sensors 1, a control box 2, a panel 3, a circuit board 4, a display instrument 5, a communication module 6 and a battery module 7.

As shown in fig. 1 and 2, a plurality of sensors 1 are uniformly distributed on a main load beam of a discharging platform, the lower ends of the sensors 1 are mounted on the main load beam of the discharging platform, and the upper ends of the sensors are connected with a bearing platform through a conversion piece. The control box 2 is hollow inside, and the panel 3 is arranged at the front side of the control box 2.

As shown in fig. 1 and 2, the circuit board 4 is provided inside the control box 2 and is connected to the sensor 1 via a signal line. The display instrument 5 is embedded on the surface of the panel 3 and is connected with the circuit board 4 through a signal wire. The communication module 6 is disposed inside the control box 2, and is connected to the sensor 1 through a communication signal line transmitted by the 4G, and outputs to the cloud server. The battery module 7 is disposed inside the control box 2 and is connected to the display instrument 5 and the communication module 6 through a power line.

Before the material platform leaves the factory, the whole system is installed, preloaded and recalibrated, the factors such as the dead weight of the platform are removed, and the early warning value and the warning value are set according to the actual customer requirements and the model of the material platform. In the working process, the intelligent instrument in the control box 2 carries out cyclic detection on the load, the load value is displayed through the display instrument 5, the load value transmitted by the sensor 1 is compared with the stored early warning value and the reference value of the alarm value, the comparison method adopts the combination of a relative comparison method and an absolute comparison method, the relative comparison method is that the range of a certain value of the stored value floating up and down is overload, the absolute comparison method is that the absolute value is set, and the overload is the overload if the absolute value exceeds the absolute value. The comparison method can achieve the purpose of self-adapting to the frame bodies with different weights, thereby ensuring the accuracy of the protection action.
