Description
Technical field
The present invention relates to a kind of digital independent device, more particularly, to a kind of monolithic for IPTV set top box troubleshooting
Machine digital independent device.
Background technology
Power supply is frequently encountered in the repairing of IPTV set top box can not open phenomenon, and IPTV set top box is using extensive collection
Into the product of circuit, due to that can not be powered to large scale integrated circuit, make in reprocessed products close to this kind of failure of 50% ratio appearance
Equipment can not repair.Manufacturer's maintenance is sent to have influence on the turnaround time, due to set top box usage amount up to millions of above, it is necessary to increase
Investment, adds standby to solve this problem, increases maintenance cost.If can accomplish that the autonomous of power control part is replaced
Change, will undoubtedly greatly improve efficiency and reduce cost.But to realize autonomous replacement, then have to read SCM program
Take, and existing low to single-chip microcomputer reading efficiency and inconvenience.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of efficiently and inexpensive
The single-chip data reading device for IPTV set top box troubleshooting.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of single-chip data reading device for IPTV set top box troubleshooting, it is characterised in that the device includes
Pre-processing device and reading equipment, the pre-processing device go encapsulation unit, cleaning unit and protection molten including what is be sequentially connected
Silk destruction unit, the reading equipment includes computer and the connecting interface being connected with each other, the connecting interface and the coring that continues
Piece is connected.
The chip to be read is immersed in encapsulation unit.
The cleaning unit includes a ultrasonic pond, cleaning agent and drier, and described cleaning agent is located in ultrasonic pond, institute
The drier stated is located at ultrasonic pond output end.
The cleaning agent includes acetone and clear water.
The protection fuse destruction unit includes a microscope and a ultraviolet lighting emitter.
The microscope magnification is more than or equal to 200 times.
The time of the ultraviolet lighting emitter irradiation chip is 6 to 8 minutes.
The computer includes burning module and decompiling module.
The decompiling module includes dis-assembling unit and C language decompiling module.
Compared with prior art, the present invention has the advantages of procedure reads single-chip data, high efficiency, low cost.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
As shown in figure 1, a kind of single-chip data reading device for IPTV set top box troubleshooting, the device includes pre-
Processing equipment 1 and reading equipment 2, pre-processing device 1 include removing encapsulation unit 11, cleaning unit 12 and protection fuse destruction unit
13, reading equipment 2 includes computer 21 and connecting interface 22, and connecting interface 22 and chip to be read 3 are connected.
When going the work of encapsulation unit 11, chip 3 to be read soaks wherein.Soak can use concentrated nitric acid, the process
Typically carry out under very dry conditions, because the presence of water may corrode exposed aluminum steel connection.
Cleaning unit 12 includes a ultrasonic pond, cleaning agent and drier.Cleaning agent includes acetone and clear water.
In ultrasonic pond, the chip first is cleaned using acetone, remnants nitric acid can be so removed, it is clear with clear water again afterwards
Chip is washed, finally by chip drier drying process.
Fuse destruction unit 13 is protected to include a microscope and a ultraviolet lighting emitter.Microscope magnification is more than
Equal to 200 times.
First enter to look for from the join-line tracks of program voltage input pin with microscope to protect fuse.Ultraviolet light is reused afterwards
Irradiator will protect fuse exposure to destroy within 6 to 8 minutes protection fuse under ultraviolet light, it should be noted that being protected with some during this
Piece (the such as lighttight scraps of paper) covers the part outside protection fuse, prevents these parts by ultraviolet light by broken
It is bad.
Computer 21 includes a burning module and a decompiling module.Decompiling module includes dis-assembling unit and C
Language decompiling module.
First by connecting interface and chip 3 to be read, first with burning module chip your burned software to being read out, but
The program read herein is binary code, also needs to be carried out decompiling afterwards with decompiling module and operate obtain source code, root
The speech selection used according to single-chip microcomputer uses dis-assembling unit or C language decompiling module to be operated.
