Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is described in further detail.
Figure 1 shows that the basic flow sheet of an embodiment of method for upgrading software of the present invention.This embodiment with set-top box as equipment to be upgraded, as follows by the basic procedure that PC carries out software upgrading to set-top box:
S101: with set-top box as client, PC as service end, between set-top box and PC, set up network linking based on socket.
The S102:PC machine transfers to set-top box with upgrade file by the network linking based on socket.
S103: set-top box receives upgrade file, upgrades its program storage.
The idiographic flow of upgrade file transmission as shown in Figure 2 in the foregoing description.To be example, describe the concrete transmission course of upgrade file in detail below as the PC of service end with as the set-top box of client.
At first, between PC and set-top box, set up network linking based on socket.
For realizing that many set-top box can be upgraded by network simultaneously in the local area network (LAN), have a plurality of software upgrading ports as the PC of service end.Suppose that the set-top box that may exist at most in the local area network (LAN) is m, PC is that the port that upgrade function is opened up is m, and the port numbers of this m port is from k to k+m.
Behind the PC software startup, at first open up m thread, socket of each thread creation creates and builds socket0 to m altogether of socketm.Each socket binds a software upgrading port respectively, and for example, socket0 and port numbers are the software upgrading port binding of k, and socket1 and port numbers are the software upgrading port binding of k+1, by that analogy.Each socket is responsible for monitoring the linking request and the request of data of the port of the port numbers of binding separately, after listening to association requests, begins to set up link, the line data communication of going forward side by side.After having set up socket, PC reads upgrade file, and monitors the linking request of set-top box.
Wait for that as the set-top box of client the user carries out the button affirmation of software upgrading, after the user confirms to carry out software upgrading, will test idle port, and when testing idle port, send linking request to this port.
Because set-top box can only be known the IP address of PC, and does not know which port of PC is occupied, thus need test with port by software upgrading PC, to obtain idle port.
If many set-top box all adopt sequential grammar to test the software upgrading port of PC in the local area network (LAN), a port may occur and be concentrated the situation of attempting link, increased of the competition of a plurality of set-top box, thereby increased the number of times of each set top box testing link idle port.The concentrated software upgrading of testing and link described PC of a plurality of set-top box reduces link efficiency with port in the local area network (LAN) in order to avoid, and set-top box adopts the software upgrading port of following method test PC, to obtain idle port:
With start-up time of set-top box as random number seed, utilize described random number seed to produce random number, and make described random number corresponding to the software upgrading of described PC port numbers with port, promptly the random number that is produced at k between the k+m.Can be by getting surplus with random number to m and then adding the method for k, make the value of the final random number that obtains at k between the k+m.
Test the software upgrading port of the pairing PC of described random number then, and judge whether this port is idle; If this port free time, directly send linking request to this idle port; If this port is busy, the next software upgrading port of loop test then is until testing idle port.
When port is used in the next software upgrading of loop test,, then carry out loop test again since k port if testing a last k+m port does not obtain idle port yet.
Because always there is difference in the time of every set-top box startup, the random number seed that different start-up times is corresponding different, and the corresponding different random number of different random number seeds, thereby greatly disperseed many port numbers that set-top box is attempted the PC of link, improved link efficiency.
Set-top box is then sent linking request to this idle port when testing idle port.
Secondly, carry out the transmission and the verification of upgrade file version information and upgrade file.
PC will be set up network linking based on socket with set-top box after listening to the linking request that set-top box sends.Simultaneously, can correctly upgrade for guaranteeing set-top box, PC at first reads the version information of upgrade file, and version information is sent to set-top box.Version information includes the information such as software version, hardware version, manufacturer's version and date issued of upgrade file correspondence.Set-top box is carried out verification to version information after receiving the version information that PC sends, and whether needs upgrading to determine this machine.If set-top box needs upgrading, then send a key bytes to PC, send upgrade file with the request PC.If judge not needs upgrading according to version information, then withdraw from escalation process, upgrading finishes.
PC judges whether to receive the key bytes of set-top box feedback.If receive key bytes, then send upgrade file; If do not receive key bytes, then abandon escalation process to this set-top box, monitor linking request again.
PC is divided into many piece of data bag of appropriate length with the data content of upgrade file, as is divided into 4M or 512K when sending upgrade file, is sent to the set-top box client respectively.After transmission finishes all upgrade files, PC will be monitored linking request again.
Set-top box receives upgrade file by the network linking based on socket, and file data is integrated.For guaranteeing the fail safe of program, in upgrade file manufacturing process, upgrade file has been carried out encryption; And, when making upgrade file, the file data before encrypting has been carried out CRC check and computing, and be attached to after the upgrade file for preventing that mistake from appearring in file in transmission.Therefore, set-top box need be to the upgrade file data decryption after receiving all upgrade files, and carries out CRC check.After the upgrade file data check is correct, storage to the FLASH program storage of set-top box, is realized the software upgrading of set-top box.If the data check mistake is not then upgraded, upgrading finishes.
