Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The remote upgrading scheme is applied to equipment system software upgrading, and solutions such as breakpoint transmission continuation, parameter backup and new parameter setting are correspondingly provided aiming at the problems that upgrading data packet transmission is interrupted, user setting parameters can be completely erased after system upgrading, new parameter point location parameter values cannot be compatible and the like in the prior art, so that the equipment upgrading does not affect the use of users.
Implementing one step:
fig. 1 is a flowchart of a remote upgrade method provided in an embodiment of the present application, where the remote upgrade method provided in this embodiment may be executed by an upper computer server and implemented in a software program. The upper computer performs data interaction with one end of the equipment to be upgraded and sends an upgrading data packet to the equipment section, so that the upgrading of the system software of the equipment is realized. One end of the device to be upgraded can be a single device, or remote upgrading of a plurality of devices can be performed.
The following description will be given by taking the host computer as an example of a device for executing the remote upgrade method. Referring to fig. 1, the remote upgrade method specifically includes:
and S11, obtaining upgrade permission returned by the equipment, sending the MD5 check code of the upgrade data packet to the equipment, and starting sending the upgrade data packet to the equipment according to the equipment return.
For example, the upper computer server may be connected to a remote device to be upgraded through the communication module, and transmit the upgrade data packet through a remote data transmission link. Before equipment upgrading is started, software code software version numbers are sent to the equipment, and the software version numbers refer to a mode of setting version numbers for software. Generally, the version number is defined by a number, and the corresponding version sequence of the software is visually represented. Of course, the software version number may have different representation modes according to actual needs. And the upper computer sends the version number to one end of the equipment to be upgraded every other set time period. After receiving the new version number, the device compares the new version number with the version number of the current device system software, judges whether the received version number is higher than the current installed version of the device, if so, the device accords with the software upgrading condition, replies an upgrade permission instruction of an upper computer to start the device upgrading process. If the received version number is not higher than the current installed version of the equipment, the software upgrading condition is not met, and the equipment replies a command which does not allow upgrading to the upper computer end.
Optionally, in order to avoid that the device does not receive the version number information sent by the upper computer due to instability of the data transmission network, the upper computer adopts a time-sharing retransmission manner to avoid a situation that the device cannot receive the version number information due to instability of the data transmission network. And the upper computer starts timing after sending the version number, if the upper computer does not receive the equipment reply after timing for one minute, the upper computer retransmits the software version number information to the equipment, and the upper computer exits from upgrading until the upper computer retransmits three times and still does not receive the reply. Of course, if the upper computer receives a reply which does not allow upgrading, the upper computer directly exits the equipment upgrading process. It should be noted that the retransmission timing and the retransmission times are set according to the actual upgrade requirement, and the present application is not limited to this.
Specifically, if the upper computer receives an upgrade permission instruction returned by the equipment, the upper computer starts an equipment upgrade process. When the device receives the upgrade data packet to upgrade the system software, the upper computer sends an MD5 check code to the device end in advance, and the MD5 check code is used for performing MD5 check operation after the subsequent upgrade data packet is received. The MD5 check checks the correctness of the data by performing a hash operation on the received transmission data. The calculated hash value is compared with the hash value transmitted with the data, and if the two values are the same, the transmitted data is complete and is not falsified (if the hash value is not falsified), so that the use can be assured. The upper computer firstly sends the MD5 check code of the upgrade data packet to the equipment end, the equipment end receives the MD5 check code and replies the upgrade permission of the upper computer, the upper computer starts to send the upgrade data packet if receiving the reply, otherwise, the upper computer does not receive the reply of the equipment to the check code, and the MD5 check code of the upgrade data packet is retransmitted to the equipment end once a minute and a minute at a time until the upper limit is sent to quit the upgrade. The retransmission time interval and the upper limit of the retransmission times are set according to actual needs, and the application is not limited fixedly.
And S12, sending the upgrade data packets to the equipment one by one, wherein the upgrade data packets comprise corresponding data packet page numbers.
When the upper computer sends the upgrading data packet, each data packet sent is provided with a crc code, and after the device receives the data packet, crc (cyclic redundancy check) is carried out. The cyclic redundancy check is one of error checking checks most commonly used in the field of data communication, and the check code is that the lengths of the information field and the check field can be arbitrarily selected. Cyclic Redundancy Check (CRC) performs polynomial calculation on data through a data transmission error detection function, attaches the obtained result to the back of a frame, and a receiving device also performs a similar algorithm to ensure the correctness and integrity of data transmission. And if the CRC of the equipment passes, replying to receive correct information, simultaneously sending the page number information of the data packet to the upper computer, and after receiving the reply, carrying out page number check by the upper computer, and if the check passes, sending the next data packet. If the checking fails or the receiving correct information replied is not received overtime, the upper computer retransmits the current data packet until the retransmission times reach the upper limit and then the upgrade is carried out. And the upper computer repeats the upgrading data packet sending operation until all upgrading data packets are sent.
After upgrading is completed, the equipment to be upgraded calculates the MD5 check code of the received upgrading data packet, compares the MD5 check code with the MD5 check code of the received upgrading data packet before upgrading, and if the comparison result is correct, replies that upgrading is successful, and sends an upgrading end mark. At this point, the device completes the upgrade.
And S13, receiving a receiving state reply returned by the equipment to be upgraded corresponding to each upgrading data packet, and confirming to enter a breakpoint state when the reply is overtime.
For example, in the actual upgrade process, the data packet transmission is interrupted, and the situation that the device exits the upgrade sometimes occurs. If the equipment is unstable in network disconnection or power failure, the equipment cannot respond to the upgrading instruction of the upper computer, and if the equipment which enters the upgrading state does not respond to the upgrading instruction of the upper computer within a continuous period of time, the equipment is indicated to respond overtime, and the equipment can automatically exit the upgrading mode and record the current upgrading information. And as the upgrade record of the breakpoint of the equipment, after the communication link is restored, the equipment uploads the upgrade record of the breakpoint to the upper computer. And after the upper computer is upgraded and powered off, whether the equipment has the upgrade record of the breakpoint or not can be detected.
In addition, if the received data packet is checked to be a data error, the device returns data packet error information, the server retransmits the corresponding data packet, and the error information is returned when the retransmission times of the same data packet reach the upper limit, the upgrading fails, and the upgrading is exited. It should be noted that, unlike the case of replying overtime, after the device replies that the upper computer fails to receive, and quits upgrading, the upper computer needs to detect whether the upgrade data packet is correct, and the next upgrade needs to start sending from the first data packet.
And S14, after the breakpoint state is confirmed to be finished or after a continuous transmission request of the equipment to be upgraded is received, starting to send the upgrade data packet from the corresponding data packet page number when the breakpoint state is entered.
It should be noted that the initiation of the breakpoint resume action may be performed by the host computer activating and the device to be upgraded to interactively confirm the end of the breakpoint state, or may be performed by the device to be upgraded automatically sending a resume request to the host computer to start the resume action. The device to be upgraded judges that the breakpoint state is finished, and may detect the data transmission network state every set time period to be upgraded, and determine that the breakpoint state is finished after confirming that the communication link is restored to normal.
Specifically, the foregoing steps S13 to S14 describe breakpoint resuming of the upgrade data packet, and the breakpoint resuming method is specifically shown in fig. 2, where:
s131, detecting the upgrade record of the equipment breakpoints.
After the device is upgraded and disconnected, the device actively detects the upgrading zone bit after exiting upgrading and/or when rebooting. Because the received upgrade data packets are stored in the equipment, the upgrade data packets all contain data packet page numbers, the upgrade flag bits of the equipment can be determined according to the data packet page numbers, the upgrade flag bits mark the interrupt nodes of the upgrade records which are not finished, and the equipment receives the upgrade data packets from the upgrade flag bits again. When the equipment detects that the upgrading records are not completed, the information is reported, and the upper computer receives the information and detects whether the equipment has the overtime upgrading records, if so, the equipment starts to enter the breakpoint continuous transmission.
S141, according to the upgrading record of the equipment breakpoints, acquiring the data package page code information corresponding to the upgrading data package which sends the breakpoints in the upgrading record.
And after the upper computer and the equipment reestablish the communication link, the upper computer starts to detect the overtime upgrading record of the equipment, and acquires the data package page code information corresponding to the data package sent by the overtime upgrading breakpoint according to the overtime upgrading record.
And S142, starting to send the upgrading data packet from the page number of the data packet of the previous breakpoint.
When the upper computer restarts sending the data packet, the step S12 is repeated, except that when the update data packet starts to be sent, the upper computer starts sending from the page number of the data packet of the last breakpoint, so as to implement the breakpoint continuous transmission function. And the upper computer starts to send the upgrading data packet from the data packet corresponding to the data packet page code according to the data packet page code information corresponding to the data packet sent by the breakpoint until the equipment upgrading is completed. The breakpoint continuous transmission function can effectively solve unstable network factors caused by equipment environment, simultaneously solve the problem that the same data packet needs to be repeatedly sent when repeated upgrading fails, and achieve the effect of saving flow.
And S15, sending the pre-backup parameter package to the equipment to be upgraded.
For example, since the actually used device has many parameters set by the user, and the upgrading of the system software program may erase all the contents and may not store the parameters set by the user, the user parameters may be lost, which may seriously affect the actual application of the user. Therefore, in the upgrading process or after the equipment is upgraded, the upper computer sends the parameter packet set by the user, which is backed up in advance, to the equipment, and the equipment sets the user parameters after acquiring the parameter packet, so that the function of backing up the user parameters is realized. As shown in fig. 3, the parameter backup is specifically as follows:
and S150, before upgrading is started, receiving all current parameter packages sent by the equipment.
Before upgrading is started, the equipment sends all data packets set by the current parameters to the upper computer, and the upper computer stores the parameter packets set by the user and returns the parameter packets to the equipment end after the equipment upgrading is completed.
And S151, sending parameter packets to the equipment one by one, wherein the parameter packets comprise parameter packet page numbers.
And in the upgrading process or after the equipment is upgraded, sending an upgrading completion instruction to the upper computer end according to the equipment, or actively sending the upgrading completion instruction to the upper computer in the upgrading process. The upper computer starts to send the parameter packets which are backed up one by one. The parameter packet comprises a parameter packet page number, and the parameter packet page number is used for subsequent check of the equipment to ensure that the parameter packet is correctly sent.
Optionally, as shown in fig. 5, the upper computer end sends the pre-backup parameter packet through the dual data communication link. The same parameter packet is sent to the equipment end through different data communication links, and the equipment end receives the parameter packet from the two communication links. The parameter packet comprises a parameter packet page number, and after the equipment end receives the parameter packet, the equipment end firstly acquires the parameter packet page number information corresponding to the parameter packet. Since the device receives the parameter packets through the two communication links, if the two communication links can stably transmit, the device receives two identical parameter packets. Then, after acquiring the page number of the parameter packet, the device judges whether the parameter packet has been received according to the comparison with the previously received and stored page number of the parameter packet, if so, discards the parameter packet, and if not, stores the parameter packet and sets the parameter. The parameter packet is sent through the dual communication link, so that the condition that the parameter packet is failed to be sent under the condition that one path of communication network is unstable can be avoided, and the redundant sending of the parameter packet is further realized.
And S152, after receiving the page number check passing information of the previous parameter packet, sending the next parameter packet to the equipment.
And the correct sending of the parameter packet is ensured through checking the page code of the parameter packet. Meanwhile, according to the page code information of the parameter packet, the equipment can receive the parameter packet in sequence, and the conditions that the parameter packet is omitted from being sent and the parameter set by a user is not completely replied are avoided.
And S153, after all the parameter packets are sent, receiving all the parameter packet information uploaded by the equipment, and performing parameter checking.
And the upper computer compares the sent parameter packet information according to all the received parameter packet information, confirms that all the parameter packet equipment completes receiving, and completes the parameter packet sending process after the verification is passed.
Optionally, as shown in fig. 4, in the process of backing up the parameter package, the upper computer stores the parameter package, and after the device is upgraded, inserts the newly added parameter point into the parameter package and sends the parameter package to the device end.
Wherein:
s161, detecting whether a newly added parameter point location exists in the protocol of the upgrading program.
And the upper computer acquires default values of all parameter point locations of the version of the current upgraded program, compares the parameter point locations of the version before upgrading, and judges whether the upgraded version has newly added parameter point locations.
And S162, storing the parameter default value corresponding to the newly added parameter point location to the parameter packet, and then sending the parameter packet to the equipment.
The upper computer judges whether the updated version has a new parameter point location, and directly sends the parameter packet; if the newly added point location exists, the upper computer inserts the default value of the newly added point location into the stored parameter packet, and then sends the default value to the equipment end, and the equipment end changes the corresponding parameter value. Therefore, the compatibility function of the upgrade program parameters is realized, and the problem of incompatibility of newly added parameters is avoided.
The user parameters sent by the equipment terminal are received in advance before the equipment system software is upgraded, the user setting parameters are pre-backed up, and after the upgrading is completed, the pre-backed up parameter packet is sent to the equipment for the parameter setting after the equipment is upgraded. The method and the device avoid the loss of user parameters caused by erasing all contents after the program is upgraded, and further influence on the actual use of the user. Meanwhile, by detecting the upgrade record of the breakpoint of the equipment, after the breakpoint of the equipment is upgraded, the upgrade data packet is sent again according to the page code of the data packet of the previous breakpoint, so that the breakpoint continuous transmission of the equipment system software upgrade is realized, the upgrade process is prevented from being repeated, and the effect of saving flow is achieved.
Example two:
on the basis of the first embodiment, fig. 6 is a flowchart of another remote upgrade method provided in the second embodiment of the present application. The remote upgrading method is executed corresponding to a device end to be upgraded, and referring to fig. 6, the remote upgrading method includes:
and S21, replying upgrade permission, receiving the MD5 check code of the upgrade data packet, and restoring the upper computer according to the MD5 check code.
And S22, sending all current parameter packets to the upper computer.
And S23, receiving the upgrading data packets sent by the upper computer one by one, wherein the upgrading data packets comprise corresponding data packet page numbers.
And S24, sending a receiving state reply corresponding to each upgrading data packet to the upper computer, confirming that the next upgrading data packet of the upgrading data packet is not received in a set time period, and entering a breakpoint state.
And S25, detecting the upgrading flag bit after the breakpoint entering state reaches the preset time, and reporting information to the upper computer according to the uncompleted upgrading record.
And S26, receiving an upgrade data packet sent by the upper computer from the corresponding data packet page number when the upper computer enters the breakpoint state.
And S27, receiving all the data packets to be upgraded, performing MD5 checking, if the checking comparison result is correct, replying that the upgrade is successful, and sending an upgrade ending mark.
And S28, receiving the parameter package which is backed up in advance.
In the remote upgrade method corresponding to the device end to be upgraded according to this embodiment, in the remote upgrade method according to the first embodiment, the remote upgrade method executed by the device end to be upgraded has corresponding functions and beneficial effects, and a specific process thereof is referred to in the first embodiment, which is not described herein again.
Example three:
on the basis of the above embodiments, another remote upgrade method provided in the third embodiment of the present application corresponds to an interactive process between an upper computer and a device to be upgraded.
The upper computer firstly sends an upgrade request to the equipment end to be upgraded, the upgrade request comprises a software code software version number, if the upgrade request meets the conditions (after the equipment receives a new version number, the received current version is judged to be higher than the existing installed version of the equipment), the equipment replies permission for upgrading. And if the upper computer receives the reply permission of the equipment, the upper computer sends the MD5 check code of the upgrading data packet, the equipment receives the MD5 check code and replies to the upper computer, the upper computer starts to send the upgrading data packet if receiving the reply, otherwise, the upper computer does not receive the reply of the equipment to the check code, and the MD5 check code of the upgrading data packet is retransmitted once per minute and so on until the upper limit is sent to quit upgrading. The upper computer sends a data packet with a crc code, the device receives the data packet and then conducts crc check, if the check is passed, the upper computer replies to receive correct data and page numbers of the data packet to the upper computer, if the upper computer receives the reply, the upper computer conducts page number check, if the check is passed, the upper computer sends the next data packet, if the check is not passed, the upper computer will resend the current data packet, and the upgrade is quit until the upper limit of the number of times of resending. And repeating the steps until the data packet is sent out, performing MD5 verification after the equipment receives all the data packets, and replying to the upper computer after the data packet is received after the verification is passed so as to finish upgrading.
And if the upper computer does not receive the equipment reply and exits the upgrade after repeating for three times during the upgrade, entering an upgrade breakpoint transition state. The device will mark as a timeout state and record the page number of the currently transmitted data packet. If the equipment is in unstable network disconnection or power failure, the equipment does not respond to an upgrading instruction of the upper computer, if the equipment which enters the upgrading state does not receive the upgrading instruction of the upper computer in a continuous period of time, the equipment can automatically exit the upgrading mode and record the current upgrading information, the equipment actively detects an upgrading flag bit after exiting upgrading or when restarting, information is reported when incomplete upgrading records are detected, the upper computer receives the information and detects whether the equipment has overtime upgrading records, and if yes, the equipment starts entering a breakpoint for continuous transmission. It should be noted that the device actively sends a resume request or the upper computer actively inquires about the end of the breakpoint state to determine whether to start the breakpoint resume.
And then, the upper computer restarts to send the upgrade data packet to the equipment terminal. The difference is that when the upgrade data packet is sent, the upgrade data packet is sent from the page number of the data packet with the last breakpoint, so that the breakpoint continuous transmission function is realized. In addition, before the upgrading is started, the equipment sends all data packets set by the current parameters to the upper computer, the upper computer stores the parameter packets, in the equipment upgrading process or after the upgrading is completed, the default values of all parameter point locations of the version of the program to be upgraded are obtained from the server, the parameter point locations of the version before the upgrading are compared, if a newly added point location exists, the default value of the newly added point location is inserted into the stored parameter packet and then is issued to the equipment to change the corresponding parameter value, and the parameter cloud backup function is achieved.
The remote upgrade method corresponding to the device to be upgraded in this embodiment corresponds to the interaction method between the host computer and the device to be upgraded in the remote upgrade methods of the first and second embodiments, and has corresponding functions and beneficial effects, which are described in detail in the first and second embodiments, and are not described herein again.
Example four:
on the basis of the foregoing embodiment, fig. 7 is a schematic structural diagram of a remote upgrade apparatus provided in the fourth embodiment of the present application.

The user parameters sent by the equipment terminal are received in advance before the equipment system software is upgraded, the user setting parameters are pre-backed up, and the pre-backed up parameter packet is sent to the equipment in the upgrading process or after the upgrading is completed, so that the parameter setting after the equipment is upgraded is realized. The method and the device avoid the loss of user parameters caused by erasing all contents after the program is upgraded, and further influence on the actual use of the user. Meanwhile, by detecting the upgrade record of the breakpoint of the equipment, after the breakpoint of the equipment is upgraded, the upgrade data packet is sent again according to the page code of the data packet of the previous breakpoint, so that the breakpoint continuous transmission of the equipment system software upgrade is realized, the upgrade process is prevented from being repeated, and the effect of saving flow is achieved.
