What is particularly worth mentioning is that, when some LCD TV just need to be upgraded the pin setting of inner several embedded hardware devices, manufacturer must disassemble the LCD TV having assembled, the embedded hardware device that again each need to be upgraded is placed in tool, just can carry out the more new element of each embedded hardware device, Zhe Dui manufacturer, will expend considerable time and cost.Therefore, certainly will need to develop the device and method of a renewal firmware that can address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of electronic installation with tough body renewal function.
The present invention has the electronic installation of tough body renewal function, comprise a reception terminal, and be electrically connected to the commutation circuit of reception terminal, the temporary storage location of an electrical connection commutation circuit, is electrically connected to the tough body unit of commutation circuit, and one is electrically connected to the CPU (central processing unit) that receives terminal and commutation circuit.Receive terminal and receive a renewal system program, CPU (central processing unit) is first controlled this commutation circuit switching and is made to receive terminal electrical connection temporary storage location, so that renewal system program is stored to this temporary storage location, CPU (central processing unit) is controlled commutation circuit switching again makes tough body unit be electrically connected to temporary storage location, so that the renewal system program that is temporary in this temporary storage location is written in the storage module of this tough body unit.
Preferably, this reception terminal belongs to an Ethernet interface, a USB interface, a RS232 interface or a HDMI interface.
Preferably, this storage module is a programmed read-only memory, and temporary storage location is a random access memory.
Preferably, temporary storage location is to be made in same chip with CPU (central processing unit).
Still a further object of the present invention, is to provide a kind of firmware updating method.
Firmware updating method of the present invention comprises following steps:
(A) one of electronic installation receive terminal reception one renewal system program;
(B) by upgrading system program, be temporary in a temporary storage location of electronic installation; And
(C) will be temporary in the tough body unit of this renewal system program writing electronic of temporary storage location.
Furthermore, step (B) is to make a central processing unit controls one commutation circuit switching of electronic installation make to receive terminal electrical connection temporary storage location, so that renewal system program is temporary in temporary storage location.
Step (C) is to make central processing unit controls commutation circuit switch make tough body unit be electrically connected to temporary storage location, so that the renewal system program that is temporary in temporary storage location is write in tough body unit.
Beneficial effect of the present invention is: electronic installation arranges a single reception terminal, and the commutation circuit of arranging in pairs or groups, allow manufacturer not need the extra tool that writes, and in the situation that does not need to disassemble, make electronic installation can intactly upgrade the upgraded version of firmware formula.
Accompanying drawing explanation
Fig. 1 is the system block schematic diagram an of the present embodiment, illustrates that the present embodiment has the design of the electronic installation of tough body renewal function; And
Fig. 2 is the process flow diagram an of the present embodiment, and the operating process of the tough body renewal of the present embodiment electronic installation is described.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1, the preferred embodiment that the present invention has the electronic installation 100 of tough body renewal function comprises a reception terminal 1, a commutation circuit 3, a CPU (central processing unit) 4, a temporary storage location 5, an input block 6, a mnemon 7 and at least one tough body unit 8, in the present embodiment, electronic installation 100 is a LCD TV.
Receive terminal 1 and receive a renewal system program from a formula original device 200, in the present embodiment, receive terminal 1 and can be an Ethernet (Ethernet) interface, one USB (universal serial bus) (Universal Serial Bus, USB) interface, one RS232 (Recommended Standard232) interface or a HDMI (High-Definition Multimedia Interface) interface etc., relatively, formula original device 200 can be that a correspondence has Ethernet interface, USB interface, the memory storage of RS232 interface or HDMI interface, in order to store, upgrade system program, common formula original device 200 is one to have the Portable disk of USB port.
CPU (central processing unit) 4 is electrically connected to and receives terminal 1, commutation circuit 3, temporary storage location 5, input block 6 and mnemon 7, in order to control the switching of commutation circuit 3, and reads renewal system program.In the present embodiment, CPU (central processing unit) 4 is a central processing unit (central processing unit, CPU), in order to carry out the computing of various formulas, and the contact of the communication between responsible electronic installation 100 units.
The temporary renewal formula having read of temporary storage location 5, it can be a random access memory (RAM), read-only memory (EPROM) that stylizes of can erasing, or a DRAM (Dynamic Random Access Memory) (DRAM), is responsible for the temporary system program that upgrades.In the present embodiment, temporary storage location 5 is to be made in same chip with CPU (central processing unit) 4.
Mnemon 7 is in order to the system program of stored electrons device 100, and in the present embodiment, mnemon 7 is a hard disk.
Consult Fig. 1 and Fig. 2, below will describe a preferred embodiment of the performed firmware updating method of the above-mentioned electronic installation 100 with tough body renewal function in detail.
First, the input block 6 of execution step S10-electronic installation 100 receives an operational order of being inputted by user, upgrades the replacing of system program to select tough body unit 8.
Then, the CPU (central processing unit) 4 of execution step S20-electronic installation 100 is controlled commutation circuit 3 switchings according to user's operational order, and make to receive terminal 1, is electrically connected to temporary storage location 5.
Step S30-reception terminal 1 receives the renewal system program of formula original device 200, and this renewal system program is sent in temporary storage location 5 temporary.What specify is, if the renewal system program in tough body unit 8 is incomplete, or the vicious formula code of tool, to make tough body unit 8 produce wrong or lose efficacy, more seriously will cause its damage, so in the process transmitting in formula, the CPU (central processing unit) 4 of electronic installation 100 can read by receiving terminal 1 the renewal system program of formula original device 200, and it is complete in reading an end label of renewal system program, to judge that renewal system program has read, so can guarantee to read complete renewal system program.
The CPU (central processing unit) 4 that enters step S40-electronic installation 100 is controlled commutation circuit 3 switchings, and makes temporary storage location 5 be electrically connected to tough body unit 8.
Step S50-electronic installation 100 is written into temporary renewal system program the storage module 81 of tough body unit 8.
In sum, electronic installation 100 of the present invention can receive the required renewal system program of tough body unit 8 by single reception terminal 1, and utilize commutation circuit 3 in the start receiving between terminal 1 and the tough body unit 8 of wish change, to read renewal system program, and change original driving formula, thus, electronic installation 100 can not need through disassemble in the situation that, drive the replacing of formula, so really can reach object of the present invention.
Only as described above, it is only preferred embodiment of the present invention, when not limiting scope of the invention process with this, the simple equivalence of generally doing according to the claims in the present invention and invention description content changes and modifies, and all still remains within the scope of the patent.
