Description

Multi-mode automobile core plate clamp judgment method and judgment system

Technical Field

The invention relates to an automobile core plate clamp, in particular to a method and a system for judging a multi-mode automobile core plate clamp.

Background

In the generation process of the automobile 4G core board, in order to ensure the quality of delivered products, a set of special production software is often designed and developed to be filled in the 4G core board for various functional tests after the products are molded. Each procedure on a factory production line has strict precedence order, and the test modules corresponding to each test procedure in the production software are synchronously matched to carry out strict precedence smooth management, namely, the test of the next procedure can be carried out only after the test of the previous procedure is finished. For example, one production line has a plurality of processes such as a process 1, a process 2, a process 3, a process 4, a process 5, etc., and the processes correspond to a functional test module 1, a functional test module 2, a functional test module 3, a functional test module 4, a functional test module 5, etc. in production software respectively, and when the production software wants to run the functional test module 2, the production software can be started only after detecting that the functional test module 1 is in a successful test state; when the generation software can run the functional test module 3, the functional test module 2 is started after being detected to be in a successful test state, and so on.

In addition, because the 4G core board is only a chip module, all function tests and test result display can be completed only by matching with a special tool clamp. After the 4G core board of the automobile is delivered to the customer, some customers need to perform full-inspection or spot-inspection on the delivered 4G core board in order to ensure the quality of the incoming material, so that some customers often purchase a certain number of tooling fixtures from a 4G core board supplier for full-inspection or spot-inspection testing, but the customers cannot test all functional test modules of the generated software canned in the 4G core board once, and often only choose the most important or most concerned functional module to perform verification testing. At this time, because each test module of the production software filled in the 4G core board cannot be started at will and must have a strict sequential operation relationship, the production software used in a factory cannot meet the requirements of customers, and often a supplier needs to provide a set of test software for the customers to fill the 4G core board by themselves for testing. The supplier needs to maintain two sets of software, one set is specially used for factory production test, the other set is specially used for customer full-inspection or sampling test, and the development and maintenance cost of the software is high due to a plurality of software systems.

Disclosure of Invention

In order to solve the above problems, the present invention provides a method for determining a multi-mode automobile core board clamp, which can automatically detect the type of the clamp and automatically enter a corresponding test mode according to the type of the clamp, and the specific technical scheme is as follows:

a multi-mode automobile core plate clamp judging method comprises the steps of judging the type of a clamp through the state of a GIPO port of a CPU, if the GIPO port is in a low level, judging the clamp to be a factory clamp, entering a factory test flow, and sequentially testing each functional module in the factory test flow according to a set sequence; and when the GIPO port is at a high level, the client acceptance fixture is used, the client acceptance flow is entered, and the client acceptance flow tests the corresponding functional module as required.

Preferably, the state of the GIPO port is controlled to be low level or high level by a judgment resistor in the judgment circuit, if the judgment circuit is provided with the judgment resistor, the judgment resistor is pulled down to form low level, and the GIPO port is low level; if the judging circuit does not judge the resistance, the GIPO port is in high level.

A multi-mode automobile core plate clamp judging system comprises a judging circuit, wherein the judging circuit comprises: the circuit comprises a triode QN410, a resistor R430 and a resistor R429, wherein the collector of the triode QN410 is respectively connected with the resistor R430 and pins E02-GPIO108 of the CPU, the base of the triode QN410 is respectively connected with a resistor R428 and pins E02-GPIO92 of the CPU through the resistor R429, and the resistor R428 is grounded; the emitter of the transistor QN410 is grounded.

Compared with the prior art, the invention has the following beneficial effects:

the multi-mode automobile core board clamp judging method provided by the invention can judge whether the clamp is a factory clamp or a customer acceptance clamp through the state of the GIPO port, and automatically enter the corresponding test flow, so that one set of software can be used for multiple hardware, the software can run different test logics according to different hardware configurations, and the development and maintenance cost of the software is reduced.

Detailed Description

The invention will now be further described with reference to the accompanying drawings.

Example one

Since 99% of the functional logics of the factory test software and the customer acceptance software are identical and only 1% of the functional logics are different, the development and maintenance costs of the software can be greatly reduced if the two pieces of software are integrated into one piece of software. However, how to identify whether the test core board fixture is a factory fixture or a customer acceptance fixture in the test process is an urgent problem to be solved.

In order to solve the problems, the work fixtures used by a factory and the work fixtures purchased by a customer can be distinguished, the circuit board designs of the two work fixtures are slightly different, and the production software filled in the 4G core board can distinguish which kind of the work fixture is used; namely, a fixed GPIO port can be designated, the output of the GPIO port is low on a tool fixture used in a factory and high on a tool fixture purchased by a customer through different circuit designs, and the state judgment of the designated GPIO is added in the software flow design. As shown in fig. 1, after the production test software is run, the state of the GPIO port is read first, and if the state of the GPIO port is low, test logic required by factory production is run, and a strict test sequence must be provided between each test module; if the GPIO port is in a high state, test logic required by customer full inspection or sampling inspection is operated, and each functional test module can be started to operate at will. One software and multiple hardwares are realized, namely the same software is operated on multiple sets of hardware configuration, and the software can operate different logics according to different hardware configurations, so that the software research and development and maintenance cost is greatly reduced.

The GIPO port is controlled to be at a low level or a high level through a judging resistor in the judging circuit, if the judging resistor is arranged in the judging circuit, the judging resistor is pulled down to form a low level, and the GIPO port is at the low level; if the judging circuit does not judge the resistance, the GIPO port is in high level.

A plurality of function test modules are placed on a desktop of the test software, and one station on a factory production line corresponds to one function test module. In order to avoid missing test items during factory assembly line work, the test of the next station is required to depend on the completion of the previous station, otherwise, the test of the current station cannot be carried out.

E02_ GPIO92 is used as an input pin, a GPIO port controlled by a CPU is directly pulled up, when an R428 resistor exists, E02_ GPIO92 is pulled down by the resistor to form low voltage, and the state is used as a judgment condition of a production clamp; when the R428 resistor is not present, the E02_ GPIO92 pin forms a high voltage due to internal pull-up, and this state is used as a judgment condition for the client clip. That is, the R428 resistor is present in the hardware circuit design of the production fixture, and the R428 resistor is not present in the hardware circuit design of the customer acceptance fixture.

After the state judgment of the appointed GPIO is added in the software process design, the same software can run different processes on different clamps.
