Embodiment
Particularly, as shown in Figure 1, one embodiment of the invention proposes a kind of automatic testing method of intelligent television, comprising:
Step S101, when the start of described intelligent television, detects the circuit of intelligent television, to determine described circuit whether fault;
In the present embodiment, described intelligent television has carried Android operation system.
When user opens intelligent television, no matter start shooting normal or start shooting exception, all automatically entering the automatic detection of television line, according to the path pre-set, automatically complete the detection of a series of circuit.
In the present embodiment, default test patterns can be inputted functional test is carried out to circuit, to determine circuit whether fault.Test patterns pre-sets when intelligent television is produced.Functional test is carried out to circuit, can without the structure of the route of pipe line how, whether correctly the test patterns of input setting just can examine the function of circuit, and distinguishes the quality of circuit according to this.Functional test is efficiently quick, although can judge the quality of intelligent television circuit very soon, but can not realize fault location.If but after determining line failure, contribute to the accurate location of next step fault point.
Step S102, if described line failure, positions the fault point of line failure, obtains the line fault signal of described fault point and exports;
Wherein, after determining line failure, the fault point of causal function method to line failure in predetermined vector can be adopted to position.
Particularly, refer to Fig. 2, step S102 comprises:
Step S1021, writes in the output response type of circuit by malfunction;
Step S1022, exports response function, and determines the position of described fault point according to described response function;
Step S1023, obtains the line fault signal of described fault point, and described line fault signal is converted to the output of Morse signal code.
Adopt the causal function method in predetermined vector test can realize the location of line fault and the detection of multiple faults, the accurate mathematical that must be made in the response of line fault situation line due to causal function method describes, namely line fault conditions (because of) write into circuit output response (really) formula in, this step is performed in intelligent television, the output response function of reflection line fault is drawn according to the actualizing technology in code, and the place of line fault is judged according to output function, record the line fault signal that fault point is corresponding.
Then, according to obtained line fault signal, convert thereof into the Morse code of standard, carry out the output of result and show.
According to the Morse code classification value preset, by the fixing flashing mode circuit fault of indicator light, the fault corresponding to the fixing flashing mode of indicator light is write in text, carries out reference for maintenance personal and user.
Step S103, if described circuit is intact and when can recognize flash memory, detect the flash memory of intelligent television, to determine described flash memory whether fault;
In the present embodiment, the flash memory of intelligent television is Nand-Flash flash memory, also can be other flash memory.
Wherein, if when the circuit of intelligent television is intact, first need to judge whether correctly to recognize flash memory, if identify, qualification is by rear, enters corresponding detecting step.
Wherein, Nand-Flash flash memory is the one of Flash internal memory, and the non-linear macrocell pattern of its inner employing, the advantages such as it is comparatively large that it has capacity, and speed of rewriting is fast, are applicable to the storage of mass data.Need to judge whether bad block as Nand-Flash flash memory is last in erasable operation, judge that the method for bad block is relevant with concrete chip, be all certain byte judging SPAREDATA during the bad block of general detection whether be 0XFF, Nand-Flash flash memory can be detected successively whether normally start, thus as system whether normally start according to one of.
Step S104, if when described flash memory breaks down, obtains flash failure signal and exports.
Wherein, if flash memory breaks down, may be that the quantity of bad block exceeds preset range, and the operation of influential system, this is the damage in flash hardware; Also may be the state performance of flash memory for excellent, this is the damage in flash software.When flash memory breaks down constantly, to be exported by signal code and by indicator light flickering display result.If during flash memory fault-free, then intelligent television normal boot-strap, can carry out other fault detect, as temperature detection or internal memory detection etc.
