Accompanying drawing explanation
Fig. 1 is flow chart of steps of the present invention.
Embodiment
Below in conjunction with accompanying drawing a kind of automobile audio of the present invention dispatched from the factory and require that method for quick and device are further described.
A kind of automobile audio dispatches from the factory and requires method for quick, and comprise checkout gear, this checkout gear comprises:
Storage module, data acquisition module, state computation module, comparison module, display module and processing module.Wherein, when after checkout gear and Devices to test success communication, data acquisition module then reads the storage element EEPROM in Devices to test, and includes the setting data district recording factory mode default setting and the fault data district recording malfunction and related data in Devices to test self diagnosis process in the storage element EEPROM of usual Devices to test.Whether the data device under test of these two data fields meets to dispatch from the factory requires larger judgement meaning.After obtaining data, state computation module then calculates data, draw a specific current state value corresponding with Devices to test current state, current state value and state reference value then compare by comparison module, state reference value is pre-stored in the storage module of Devices to test, finally result is presented on display module.
As shown in Figure 1, its concrete automobile audio dispatches from the factory and requires that fast detecting side comprises method following steps:
S10. checkout gear control Devices to test powers on, and then checks whether Devices to test powers on or factory reset first after the power-up; If whether Devices to test powers on or factory reset first, perform step S20, otherwise perform step S30.
S20. when be judged to be Devices to test power on first or factory reset time, checkout gear controls its storage element of Devices to test initialization, make it set up and get setting data district and fault data district, and then obtain the data of the various module status of representative Devices to test in setting data district and fault data district.
S30. checkout gear then directly reads storage element, and obtain the data in setting data district and fault data district from storage element, and the state reference value having these data to calculate to represent Devices to test to meet to dispatch from the factory equipment fault data and setting data when requiring corresponding.
S40. described checkout gear obtains the current fault data of Devices to test and/or current setting data, and calculates the current state value of current state.
Preferably, in the present embodiment, state reference value includes the Operation system setting state reference value of computing and the misdata state reference value of representative system mistake of representative system setting.These two reference values in actual detection computations process can only to wherein one calculate.And in like manner, current state value also includes Operation system setting state value and misdata current state value in the ban.Above-mentioned current state value and state reference value comprise following calculation procedure:
S41. the data of all characterization device states in the storage element of described Devices to test or Devices to test current setting data and fault data is extracted;
S42. do XOR to the data in step S41, final one obtains described state reference value or described current state value.
S50. current state value compares with state reference value, judges whether Devices to test meets requirement of dispatching from the factory according to comparing result.
In addition, detection method also comprises step display:
S60. the logotype that checkout equipment is different according to the judgment result displays of step S50.
Concrete the invention provides two displaying schemes:
The first, when current state value is equal with state reference value, display module shows a specific logotype, represents to meet and dispatches from the factory and eats refined initialized requirement, otherwise do not show, and foot with thumb down dispatches from the factory initialization requirements.
First scheme, when when current state value is equal with state reference value, display module shows a specific logotype, represents that meeting dispatches from the factory and eats refined initialized requirement; If do not meet when dispatching from the factory initialization requirements, what judge Initialize installation and have in these two conditions of fault does not one or morely meet, and shows corresponding special icon.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned execution mode, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
