Detailed Description
The technical solutions of the present invention are described in detail below by examples, and the following examples are only exemplary and can be used only for explaining and explaining the technical solutions of the present invention, but not construed as limiting the technical solutions of the present invention.
As shown in fig. 1, a touch screen testing system for a vehicle-mounted entertainment system includes an upper computer system 1, which includes an operating system and a software development environment, and is used for developing program codes and setting a program execution flow and a determination rule.
As shown in fig. 2, the upper computer system develops control instructions corresponding to the respective functions of the component under test based on the control interface protocol of the component under test, and sorts the control instructions.
The code communication protocol of the specific control instruction comprises a character segment consisting of a protocol head, a protocol total length, a main function serial number, a sub-function serial number, a parameter length, a parameter and a check bit, wherein the code length of the control instruction in the embodiment is shown in a table I:
watch 1
Wherein,
protocol header: a protocol initiation identity;
protocol overall length: total number of bytes of the complete protocol;
main function sequence number: a primary function identification code;
sequence number of subfunction: the sequence number of the corresponding sub-function under the main function;
length of parameter: setting parameter length required by the subfunction;
parameters are as follows: setting specific values of parameters required by the subfunctions;
checking the bit: the complement of the sum of the calculated values for all bytes except the protocol header and the validity bit.
The details are shown in table two:
watch two
And simultaneously, the upper computer system sets an effect diagram expected to be presented by each control instruction according to the function corresponding to the control instruction and the design specification, and sends the effect diagram to the real-time processing system.
The real-time processing system 2 is used as a program execution module, converts a code program into a control signal according to a set execution flow, outputs the control signal to a controller 4 of the tested part through a communication line 3, simultaneously receives and analyzes picture information collected by a high-definition camera 6, compares an effect picture with the collected picture according to a judgment rule, judges whether the function of the entertainment system is realized and analyzes whether a place needing to be improved exists in the function, and feeds a judgment result back to the upper computer system.
