As shown in fig. 7, the force calculation device in this embodiment includes a control main board and a force calculation board which are arranged in a module, the control main board is arranged on one side of the force calculation board, the MCU chip is arranged on the control main board, a connection interface is arranged at an end of the force calculation board, the force calculation board is embedded with a plurality of force calculation chips, the connection interface is connected to the force calculation chip, and the control main board is connected to the force calculation board through the connection interface, so as to realize the communication positioning of the MCU chip on the force calculation chip. The MCU chip has the chip functions of memory, counter, A/D conversion, data transmission, recording and the like, and can perform data transmission and data processing with the computing power chip.

The connection interface may include at least one of a serial port, an RS232 (asynchronous transfer standard interface), a USB interface, an ethernet interface, a PCI interface, and a PCIE interface.

The PCI interface is a peripheral component interconnection standard interface, the force calculation board adopts an aluminum-based material which is beneficial to rapid heat dissipation as a substrate, a plurality of force calculation chips are embedded on the force calculation board, a wiring layer is arranged between the aluminum-based substrate and the back of the force calculation chips and used for communication wiring on the back of the force calculation chips, and the connection interface 402 is connected with the force calculation chips.

The force calculation board is provided with components, and the components include but are not limited to crystal oscillators arranged on one side of each force calculation chip. In order to further acquire corresponding positioning information of the force calculation chip, a plurality of components can be arranged on the force calculation board, each component is correspondingly arranged on one side of each force calculation chip, and the MCU chip can acquire corresponding positioning information after communicating with the force calculation chip, wherein the components include but are not limited to a crystal oscillator, a phase-locked loop (PLL) and the like.

This embodiment is through setting up the MCU chip in the control mainboard, establishes the communication connection between MCU chip and the power of calculating chip for the power of calculating chip position that breaks down in the power of calculating board can be fixed a position fast to the MCU chip, reduces the influence of equipment trouble to the productivity effect.

Finally, only specific embodiments of the present invention have been described in detail above. The invention is not limited to the specific embodiments described above. Equivalent modifications and substitutions by those skilled in the art are also within the scope of the present invention. Accordingly, equivalent alterations and modifications are intended to be included within the scope of the invention, without departing from the spirit and scope of the invention.
