Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the following examples are only for more clearly illustrating the technical aspects of the present invention, and are not to be construed as limiting the scope of the present invention.
Example 1
As shown in fig. 1, the method for non-inductive upgrade of an intelligent terminal provided by the embodiment of the invention comprises the following steps:
s1, acquiring a new demand and a firmware package, updating the firmware package according to the new demand, and simultaneously giving out a frame identification of the new firmware package.
And acquiring new requirements set by an on-line upgrading control system of the human or monitoring center, optimizing and updating the firmware package according to the new requirements to obtain a new firmware package, and giving out frame identification of the new firmware package.
S2, timing the main collector, dividing the new firmware package into a plurality of upgrading packages according to frames, and transmitting the upgrading packages to the main collector, and checking the frame identification of the upgrading packages by the main collector to confirm that the upgrading packages belong to the new firmware package.
As shown in fig. 3, the online upgrade control system of the monitoring center divides the new firmware into a plurality of upgrade packages according to frame packages through the wireless network, and sequentially transmits the upgrade packages to the main collector from the 0 th frame, and the main collector checks the frame identification of the received upgrade package to confirm that the upgrade package belongs to the new firmware package, namely, invokes the firmware interactive program to verify.
The upgrade codes passing the verification are stored in the external memory FLASH chip, and the firmware interactive program feeds back the frame numbers of the received upgrade packages to the monitoring center. And the monitoring center sequentially transmits the next frame of upgrade package according to the received feedback information, and the process is circulated until the monitoring center finishes transmitting the last frame of upgrade package (namely, ending the frame).
The embedded processor of the main collector is an ARM9 series 32-bit processor STM32F207, can support the operation of an embedded real-time operating system, the on-chip FLASH of the main collector supports an on-line programming technology, and the STM32F207 processor is provided with an on-chip FLASH code area of 1MByte, so that the code area is divided into two functional areas during the embedded programming for realizing the on-line upgrading: a boot zone and a run zone.
When the equipment is started, a boot area program is firstly run, the program firstly initializes an external memory FLASH, and checks whether a complete new firmware package upgrading code exists in a fixed address on the FLASH. If so, starting a firmware code coverage flow: and unlocking the on-chip FLASH, calling an on-chip FLASH block operation function to erase the original codes of the running area, writing new codes into the on-chip FLASH running area of the processor according to the sequence, and locking the on-chip FLASH to inhibit the running codes from being rewritten during normal running. The code is written into the run-time area in turn. When the last byte is burnt, the boot program will clear the upgrade code in the external memory FLASH, and then restart the device. If the boot program does not find the complete upgrade code in the external memory FLASH, executing the normal operation flow: the operation area is jumped to a starting address of an operation area, a bus and a clock are initialized, interrupt enabling is performed, a data structure is initialized, and tasks such as data acquisition, processing and transmission are started to be executed.
The monitoring center transmits the new firmware package to the main collector, and data is transmitted through wireless sub-packets, and the specific flow is shown in fig. 4.
The wireless sub-package transmission interaction process through the mobile public network is mainly completed through 3 programs, namely an online upgrade control system and a sub-package framing unit which are positioned on an automatic station monitoring center server and a firmware interaction program which is positioned in a main collector, wherein the sub-package framing unit is used for dividing a new firmware package into a plurality of upgrade packages according to frames, and the online upgrade control system is used for transmitting the upgrade packages to the main collector.
The online upgrade control system is a subsystem of the automatic station monitoring center, and is used for inquiring version numbers of intelligent terminal equipment observed by networking and initiating automatic upgrade. When a certain station on the observation network of the automatic station is found to need to upgrade firmware, the network parameters and the SIM card IP address corresponding to the station are searched and set through the monitoring center database, and then the latest firmware code file is opened. After starting transmission, a new firmware code file is read in a binary mode, the total frame number required to be transmitted in a subpacket mode is calculated according to the file size and the maximum capacity allowed to be transmitted by each frame, and then a framing function is called to generate a firmware upgrading frame.
Starting from the 0 th frame, the framing function firstly checks the reasonability of the current frame number, and if an abnormal condition occurs, the framing function exits from the upgrading and records the upgrading in the log file. And under normal conditions, calculating an offset address of the upgrade code read from the file according to the current frame number, and calculating the check code. And finally, combining the frame header, the frame number, the total number, the frame length, the upgrade code, the check code and the ending symbol together to form a complete upgrade package. The upgrade package is sent to the wireless communication module through the Internet and the mobile base station, finally, after the upgrade package sent by the monitoring center is received by the serial port monitoring program of the collector host computer, the frame identification is checked, and if the upgrade package is confirmed to belong to the firmware package, the firmware interaction program is entered for processing. The program first reads the frame number and the total number (the total number of frames of the upgrade package). If the frame 0 is received, the program erases the appointed block address in the external memory Flash so as to write the content of the upgrade package, and if the erasing fails, the collector returns failure information to inform the online upgrade control system that the equipment does not have online upgrade capability; when the frame number is greater than 0, checking whether the current number is a continuation of the last received number, and for the packets with continuous numbers, checking, calculating and writing the packets into the Flash; and discarding the discontinuous packets, and feeding back the frame numbers which are correctly received last time to the online upgrade control system so as to enable the monitoring center to resend the upgrade packets. And when the firmware interactive program correctly receives the last frame of upgrade packet, writing the data packet and the upgrade identification into the external Flash. After finishing important tasks such as minute statistics, positive point data uploading and the like, the collector host computer is restarted automatically, and the work of erasing old firmware and burning new firmware is finished in the Flash in the chip.
The wireless packet transmission data includes breakpoint resume, and a flow of the breakpoint resume mechanism provided by the embodiment of the invention is shown in fig. 5.
Specifically, the wireless communication module may fail to restart; the mobile base station channel allocation or network congestion may cause the wireless communication module to be offline for a period of time and then to be re-online, which is a frequent occurrence. The breakpoint continuous transmission ensures that under the condition that any frame of upgrading packet is lost or the code is changed, the upgrading system can also start to continue to transmit at the lost code segment, and ensures that the collector host finally receives the complete and correct code.
The online upgrade control system monitors the upgrade process and waits to receive feedback information after each frame is transmitted, as shown in the following figure. When the control system sends the nth frame upgrade package, 2 kinds of feedback information are received: the collector returns number N or number N-1. The return number N indicates that the nth frame has been received for storage, at which time the control system will continue to send the n+1th frame upgrade package; the return number N-1 indicates that the collector received the nth frame but did not pass the check, at which time the control system will continue to send the nth frame upgrade package. There are also 2 cases where no feedback information is received: the nth frame does not reach the collector or the collector returns the number N but is not received by the control system. In both cases, the control system does not receive the correct return information, and after monitoring for a period of time, the control system tries to send the nth frame upgrade packet again, if the control system tries to receive the return information for 5 times, the control system pauses automatic upgrade, displays abnormal receiving and transmitting information, and waits for manual intervention. The breakpoint continuous transmission mechanism online upgrade control system adopted by the design is an initiative, and the task and algorithm complexity of the automatic station collector are reduced as much as possible. The complex wireless signal environment facing the automatic station can still ensure that the upgrade package written into the external Flash by the collector cannot be deleted or repeated, thereby enhancing the reliability of wireless transmission.
S3, merging the upgrade package into a new firmware package after the transmission is completed, checking whether the new firmware package is complete or not through a boot area program of the main collector, covering the new firmware package to an operation area of the main collector if the new firmware package is complete, operating the new firmware package after the new firmware package is successfully covered, automatically restarting the main collector in a non-busy time, finishing the noninductive upgrade of the intelligent terminal, and adopting a low-priority response strategy when the upgrade package is processed.
After the main collector receives the last frame of upgrade package and checks the upgrade package, the main collector automatically restarts in the non-busy time, checks whether the external memory FLASH has a complete new firmware program through the boot area program, and then calls the firmware update program to cover the new program to the operation area strictly according to the code sequence, and the new program is operated after the coverage is successful.
In the invention, the reliability and noninductive performance of firmware upgrade are more important than the upgrade speed, the average time for sending upgrade frames and receiving feedback information is longer under the influence of the complex route of the mobile public network and the low priority strategy of the collector end, but the upgrade is still reliably completed; from the breakpoint continuous transmission condition, the complexity of the transmission network affects not only the transmission time, but also the transmission quality, and may cause the transmission timeout or partial transcoding of the upgrade frame or the feedback information, so the number of automatic continuous transmission attempts of the upgrade control system should be properly increased to reduce the probability of manual intervention as much as possible.
The non-inductive upgrade strategy used in the present invention includes a time synchronization strategy, a low priority corresponding strategy, and an autonomous upgrade strategy, as shown in fig. 6.
The data acquisition of the intelligent terminal is divided into two parts: the digital signal acquisition based on interrupt response and the analog signal acquisition based on cyclic tasks increase the external interrupt response frequency in the upgrade package receiving process, and influence the analog signal acquisition period. The automatic station data processing and storing functions are mainly completed through a circulation structure task, and the display screen refreshing and observation data wireless transmission tasks are performed through clock interrupt response, so that higher response priority is required. In the upgrading process, an appropriate strategy is adopted, the influence of file transmission and equipment restarting on an observation task is reduced as much as possible, abnormal fluctuation of observation data is avoided, a terminal user cannot feel that the equipment is being upgraded, and the 'noninductive' performance of the whole upgrading process is realized.
The noninductive upgrading method adopts 3 strategies. First is a time synchronization strategy. After the online upgrade control system starts the upgrade, the master collector of the upgraded intelligent terminal is time-calibrated before the 0 th frame of upgrade packet is transmitted. Because the important tasks of the automatic station collector are all in a cross-minute or cross-hour time, the task period and the time length are predictable, and the control system can avoid the busiest time of the collector to send an upgrade data packet after time synchronization, thereby reducing the influence of upgrade packet receiving and feedback on the observation service. And secondly a low priority response policy. Because reliability and noninductive performance are more important than quick in the upgrading process, the collector can reduce the priority of processing the upgrade package: and (3) putting the interrupt response program into the embedded system to run, checking the check code of the upgrade package, writing the check code into the Flash, and sending feedback information after completing data acquisition, display, storage and transmission. And meanwhile, a monitoring program of the control system needs to set longer timeout time to match with the information feedback speed of low priority. Finally, an autonomous upgrade strategy. After the upgrade control program sends the upgrade package, the collector restarting time is not specified by the control system or triggered by a command. After the collector receives the last frame of upgrade package, the integrity mark is written into the appointed address of the external memory Flash, and then the idle time of the embedded task is selected to automatically restart and realize program upgrade within one minute.
According to the intelligent terminal non-inductive upgrading method provided by the embodiment of the invention, a subcontracting transmission interaction method and a breakpoint continuous transmission mechanism with good fault tolerance are designed by taking the delay characteristic of a wireless transmission network, the capacity limit of a wireless transmission module and the priority of a collector work task into consideration, and the influence on a main task is avoided by adopting a reasonable strategy in software operation; the method can ensure that the normal operation of the equipment is not influenced in the process of firmware package transmission through the breakpoint continuous transmission method, meanwhile, the restrictions of various factors such as a network transmission mechanism and a communication module buffer memory are also considered, the firmware package can be transmitted to the intelligent terminal for many times, the intelligent terminal has good fault tolerance performance, through the online noninductive upgrading system and the online noninductive upgrading method, the terminal user can avoid the situation that the equipment is not upgraded when the user uses busyness, the terminal user can not feel that the equipment is upgraded, the server of the cloud is linked through the network card to carry out the mounting of the upgrade file, the high-capacity local memory is not needed, the production cost and the later maintenance cost of the equipment are greatly reduced, the user experience is enriched, and the upgrade risk is reduced.
