Embodiment Construction
[0033] In this embodiment, the hardware architecture of the communication method between the application and the lower computer can be as follows figure 1 shown. figure 1 Including one upper computer and multiple lower computers, where the solid line indicates that the upper computer and the corresponding lower computer are connected on the physical layer or the link layer and the working status of the lower computer is turned on, and the dotted line indicates that the upper computer and the corresponding lower computer are connected The connection between the corresponding lower computers has been established but the working status of the lower computers is not open. There is no arrow connection between the upper computer and the lower computer, which means that the connection between the upper computer and the lower computer is not established. For example, when the upper computer is a personal computer with a USB interface, and the lower computer is an instrument with a dat...

The invention discloses a communication method with a lower computer, an upper computer, a computer system and a storage medium. The method for communicating with the lower computer comprises the steps of acquiring an interface handle, registering the interface handle, performing a connection test with the corresponding lower computer through the interface handle, and communicating with the lowercomputer through the interface handle when the result of the connection test is successful. The upper computer executes the method for communicating with the lower computers in the embodiment, can communicate with the lower computers at the same time, has a multi-channel measurement function, and is convenient for setting multiple groups of experiments to achieve the purposes of comparison and thelike when being applied to experimental data acquisition. Compared with the prior art, a complex and expensive multi-channel test instrument does not need to be used, and a plurality of upper computers do not need to be arranged to be in one-to-one correspondence with the lower computers, so that the experiment cost is saved. The method is widely applied to the technical field of computers.
Description
technical field [0001] The present invention relates to the technical field of computers, in particular to a communication method with a lower computer, an upper computer, a computer system and a storage medium. Background technique [0002] Scientific measuring instruments usually adopt the upper and lower computer structure, that is, the hardware circuit with circuit driving and data acquisition functions is used as the lower computer, and the device with interaction and data processing functions is used as the upper computer. 232 interface, Ethernet, Bluetooth or WiFi and other communication protocols. In such a structure, the data generated in the scientific experiment is measured and collected by the lower computer, and the data is uploaded to the upper computer for processing. [0003] Existing scientific measuring instruments communicate in a one-to-one manner, that is, one upper computer is only connected to one lower computer. In the process of using scientific me...
