Abstract
The utility model belongs to the technical field of television production, and in particular relates to a television off-line upgrading tool which mainly comprises a 51-series microcontroller, a FLASH memory, a UART serial port interface circuit, an I2C interface circuit, an interrupted circuit, a power supply circuit and a state indicating lamp. The television off-line upgrading tool can serve as a slave device to receive and store upgrading software data from a PC, and serve as a master device to send the upgrading software data stored to a television which stores and runs the upgrading software to upgrade software. The television off-line upgrading tool is easy for operation and convenient for use, and can shorten software upgrading time and reduce upgrading cost. Batch upgrading and maintenance for televisions in factories, maintenance shops and hotels can be carried out, which greatly improves efficiency.
Description
Technical field
The utility model belongs to televisor manufacturing technology field, is specifically related to a kind of televisor upgraded in offline instrument.
Background technology
Along with the enhancing day by day with function of improving constantly of TV digital degree, the upgrading of TV set software seems more and more important.Various television fault problems generally all need to adopt the mode of software upgrading to solve.The upgrade method of conventional television software mainly is by special software burning instrument, software is burnt be entered into storer, then storer is welded on the TV SKD; Or computer PC linked to each other with televisor, by computer PC the program of upgrade software is written in the storer of TV SKD.There is complicated operation in the method for these two kinds of TV set software upgrades, and the running time is long, and cost is higher, and needs deficiencies such as professional knowledge.Especially in batches televisor is carried out the occasion of upgrade maintenance at needs such as factory, maintenance factory, hotel managements, above-mentioned two kinds of methods seem backward.
Summary of the invention
The utility model purpose is to provide a kind of televisor upgraded in offline instrument, by adopting based on 51 series monolithics, and upgrading tool that can independent operating, the upgrading of realization software.
Technical solution of the present utility model is: a kind of televisor upgraded in offline instrument, mainly form by 51 series monolithics, FLASH storer, UART serial interface circuit, I2C interface circuit, interrupt circuit, power-supplying circuit and status indicator lamp etc.The internal module of this upgrading tool is the center with 51 series monolithics, connect interrupt circuit, status indicator lamp, 5V/3.3V level conversion, the 5V/3.3V level conversion connects the FLASH storer, and internal module connects UART serial interface circuit, I2C interface circuit and power-supplying circuit by circuit.
51 series monolithics have inner ROM storer, the boot of this upgrading tool self, initialize routine and UART interface data read-write program, I2C interface data read-write program etc. all leave in the inner ROM storer of 51 series monolithics, and the FLASH storer is stored the data of televisor upgrade software specially.
This upgrading tool is controlled red/green pilot lamp by 51 series monolithic timer internals and I/O mouth, with the expression current state.
Power-supplying circuit provides 5V, 3.3V two kinds of direct supplys for this upgrading tool.
When using this televisor upgraded in offline instrument, at first upgrading tool is as slave, the upgrade software data that reception computer PC sends over are also stored, upgrading tool is as main frame then, the upgrade software data of storage are sent to televisor, televisor is realized the upgrading of software with data storage, the operation of upgrade software.
The beneficial effects of the utility model are: simple to operate, easy to use, shorten time of software upgrading greatly, reduced the cost of upgrade job, be convenient in batches televisor be carried out upgrade maintenance, can significantly raise the efficiency in occasions such as factory, maintenance factory, hotel managements.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Synoptic diagram when Fig. 2 implements for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of televisor upgraded in offline instrument mainly is made up of 51 series monolithics, FLASH storer, UART serial interface circuit, I2C interface circuit, interrupt circuit, power-supplying circuit and status indicator lamp etc.The boot of upgrading tool self, initialize routine and UART interface data read-write program, I2C interface data read-write program etc. all are placed among the inner ROM, and the FLASH storer is stored the data of televisor upgrade software specially.
This upgrading tool is controlled red/green pilot lamp by 51 series monolithic timer internals and I/O mouth and is expressed current state, and for example traffic lights are all bright, and the upgrading tool operation is normal, prepares read-write; Red light is bright, and green light flashes, and upgrading tool is just at write or read FLASH storer.After overtesting and exercise, a staff can operate 5 TV upgraded in offline instruments simultaneously, obviously increases work efficiency.
With reference to accompanying drawing 2, the embodiment of upgrading tool mainly comprises two parts, as slave, receives and store the televisor upgrade software data that computer PC sends; As main frame, send the televisor upgrade software data of storage to televisor.Through the operation of two steps, finish the upgrading of TV set software.
More than describing in detail is preferred embodiment of the present utility model; this embodiment is not in order to limit claim of the present utility model; allly do not break away from equivalence enforcement or distortion, the improvement etc. that the utility model is done, all should be included within the protection domain of the present utility model.
Claims (2)
1. televisor upgraded in offline instrument, mainly form by 51 series monolithics, FLASH storer, UART serial interface circuit, I2C interface circuit, interrupt circuit, power-supplying circuit and status indicator lamp etc., it is characterized in that: the internal module of this upgrading tool is the center with 51 series monolithics, connect interrupt circuit, status indicator lamp, 5V/3.3V level conversion, 5V/3.3V level conversion connects the FLASH storer, internal module connects UART serial interface circuit, I2C interface circuit and power-supplying circuit by circuit.
2. TV upgraded in offline instrument according to claim 1 is characterized in that: described power-supplying circuit provides 5V, 3.3V two kinds of direct supplys for this upgrading tool.
