Detailed description of the invention
Fig. 1 is step flow chart of the invention.
Specific embodiment
Rapid detection method and device is required to make into one a kind of automobile audio factory of the invention below in conjunction with attached drawing
The description of step.
A kind of factory of automobile audio requires rapid detection method, including detection device, which includes:
Storage module, data acquisition module, state computation module, comparison module, display module and processing module.Its
In, after detection device and Devices to test success communication, data acquisition module then reads the storage element in Devices to test
EEPROM, and in the storage element EEPROM of usually Devices to test include the setting data that record has factory mode default setting
Area and record have the fault data area of malfunction and related data during Devices to test self diagnosis.Two data
Whether the data device under test in area, which meets factory, requires have biggish judgement meaning.After obtaining data, state computation mould
Block then calculates data, obtains a specifically current state value corresponding with Devices to test current state, and compares mould
Current state value is then compared by block with state reference value, and state reference value is pre-stored in the storage module of Devices to test, most
The results are shown on display module afterwards.
As shown in Figure 1, it includes method following steps that its specific automobile audio factory, which requires quick detection side:
S10. detection device control Devices to test power on, then check after the power-up Devices to test whether power on for the first time or
Factory reset；If Devices to test powers on for the first time or factory reset thens follow the steps S20, no to then follow the steps
S30。
S20. when being determined as that Devices to test powers on for the first time or when factory reset, detection device controls Devices to test
Its storage element is initialized, it is made to set up setting data field and fault data area, and then obtains setting data field and event
Hinder the data of the various module status of representative Devices to test in data field.
S30. detection device then directly reads storage element, and setting data field and fault data are obtained from storage element
The data in area, and calculated by the data and to represent Devices to test to meet equipment fault data when factory requires corresponding with setting data
State reference value.
S40. the detection device obtains the current fault data of Devices to test and/or current setting data, and calculates
The current state value of current state out.
Preferably, in the present embodiment, state reference value include represent system setting system setting state reference value and
Represent the wrong data state reference value of system mistake.The two reference values can be only to wherein in actually detected calculating process
One is calculated.And similarly, current state value also includes system setting state value and the current shape of wrong data in the ban
State value.Above-mentioned current state value and state reference value includes following calculating step:
S41. it is current that the data of all characterization equipment states or Devices to test in the storage element of the Devices to test are extracted
Data and fault data are set；
S42. XOR operation is done to the data in step S41, finally obtain the state reference value or described works as
Preceding state value.
S50. current state value judges whether Devices to test meets factory according to comparing result compared with state reference value
It is required that.
In addition, detection method further includes display step:
S60. the detection device logotype different according to the judgment result displays of step S50.
The specific present invention provides two displaying schemes:
The first shows a specific figure mark when current state value is equal with state reference value on display module
Will, expression meet the requirement of factory initialization, otherwise do not show, the sufficient initialization requirements that dispatch from the factory with thumb down.
Second scheme shows a specific figure when current state value is equal with state reference value, on display module
Shape mark indicates the requirement for meeting factory initialization；If do not meet factory initialization requirements, judge Initialize installation and
One or more in the two faulty conditions are unsatisfactory for, and show corresponding special icon.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be without departing from the purpose of the present invention
Various changes can be made.
