Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
In embodiments of the present invention, by HHU working group is set, realizes not needing upgrading to the wireless communication module of the node to be upgraded in the working group to upgrade to the scene by the mode that sends AKU, convenient, fast.
Below in conjunction with specific embodiment realization of the present invention is described in detail:
Embodiment one
Fig. 1 shows the realization flow of the method for the remote upgrade wireless communication module that the embodiment of the invention one provides, and present embodiment is applicable to be undertaken by the mode of broadcasting the scene of remote upgrade, and details are as follows:
In step S101, obtain the radio node in the channel.
Handheld unit HHU has the high-performance palm machine that has multiple communication modes, radio-frequency (RF) identification (Radio Frequency Identification is equipped with, RFID), the infrared head of electric power, wireless communication module, SMS module, RS485 line, both can carry out copy reading, data were set electric energy meter at the scene, also can image data and upload in master station computer, topmost function is long-range program to wireless communication module to upgrade, organize into groups, to arrange messaging parameter, makes things convenient for data acquisition.Wireless communication module by HHU carries out the transmission of data, having power consumption few, reduces wiring, and speed is fast, and data such as are difficult for losing at the advantage.
In the present embodiment, HHU adopts WINCE6.0 operating system, is equipped with the micropower wireless communication module of 433MHz.The wireless communication module of HHU automatically sending node scan channel order is searched for the radio node that frequency satisfies 433MHz, if relevant radio node is arranged in the channel, then list all radio nodes in the channel, this radio node is electric energy meter or the collector of built-in wireless communication module.One large characteristics of the electric energy meter of built-in wireless communication module or collector are, can gather by the low pressure concentrator data of each radio node, and process, store, simultaneously can and master station computer or HHU carry out exchanges data.
In step S102, working group is set, with described radio node as described working group from node.
In embodiments of the present invention, HHU can search the frequency radio node identical with self frequency, with those radio nodes as in the working group from node, self is as host node, form a hypotactic working group, then can select one in the working group from node this wireless communication module from node to be upgraded, can effectively manage radio node.
In step S103, determine that according to the selection instruction of input a described node from node is node to be upgraded.
In step S104, according to predetermined byte-sized total AKU is resolved into a plurality of sub-AKUs.
In the present embodiment, HHU at first reads upgrade file, and the data of intercepting from address 0XC000 to 0XE000, data in this address realm are the upgrading valid data, from the upgrading valid data, decomposite vendor code, chip code, version date, version number again, to judge according to these information whether described upgrade file is accurate.Then calculate the length of upgrading valid data, all upgrading valid data as a total AKU, according to data length and the chip code of total AKU, are resolved into described total AKU the independent sub-AKU of 128 bytes or 64 byte-sized automatically.To the decomposition of total AKU, make large upgrade file resolve into many little upgrade files of N, alleviated the operating pressure of node to be upgraded, guaranteed the success rate of upgrading.
In step S105, send one by one described a plurality of sub-AKU to described node to be upgraded, until all sub-AKUs are sent.
In embodiments of the present invention, when the wireless communication module that will treat upgrade node was upgraded, HHU opened two threads, and wherein, the first thread is responsible for sending according to the order of sequence one by one described a plurality of sub-AKU to described node to be upgraded; Every the sub-AKU of the second thread monitor return frame, if there is sub-AKU to send unsuccessfully, then reissue extremely described node to be upgraded of described sub-AKU by described the second thread, until described sub-AKU sends successfully.
Details are as follows:
The first thread sends sub-AKU according to the order of sequence, after every sub-AKU is sent, sends next attached bag, and every sub-AKU is with sequence number, and sequence number is unique.
Every the sub-AKU of the second thread monitor return frame, when a certain sub-AKU sends unsuccessfully, the second thread is responsible for reissuing this sub-AKU, this sub-AKU sequence number is constant, until transmission accurate till.
The advantage that multithreading is processed is when a total AKU is divided into many sub-AKUs of N, if there is a certain sub-AKU to send unsuccessfully in the escalation process, has the system of reissuing this moment, and main ROMPaq is still being carried out, because every sub-AKU has strict sequence limit, in the usual way, when there being arbitrary sub-AKU to send unsuccessfully, must re-execute escalation process.The processing of multithreading has greatly improved success rate for upgrading and has saved update time, and wall scroll sends and is expected to be 30 minutes nodes, and the update time of each node of multithreading shortens to 15 minutes.
Concrete, send sub-AKU to node to be upgraded by sending sub-AKU order, this frame format that sends sub-AKU order is as shown in table 1, wherein, this command word that sends sub-AKU order is 8DH, the command word DD of parameter comprises data content, 3 attributes of data format and byte number, wherein data content comprises the packet sequence number, data length and upgrade data, data format is the packet sequence number, the data format that data length and upgrade data adopt, be HEX, byte number is the packet sequence number, the maximum number of byte of data length and upgrade data, as shown in table 2, wherein, when data length is 0, and when wearing the total CRC of 2Byte ROMPaq after the order, represent that sub-AKU is sent.
Table 1
| Data content | Data format | Byte number |
| The packet sequence number | HEX | 1 |
| Data length | HEX | 1 |
| Upgrade data | HEX | This bag data length |
Table 2
Concrete, the frame format of returning frame of every sub-AKU is as shown in table 3, and wherein, parameter is packet sequence number+00 o'clock, for correctly replying, represents that sub-AKU sends successfully; When parameter is packet sequence number+FF, be wrong responses, represent that sub-AKU sends unsuccessfully.Need to prove, do not need to reply acknowledgement frame during the broadcasting upgrading.
Table 3
Present embodiment arranges working group by HHU, realizes not needing upgrading to the wireless communication module of the node to be upgraded in the working group to upgrade to the scene by the mode that sends AKU, and is convenient, fast.In addition, to the decomposition of total AKU, make large upgrade file resolve into many little upgrade files of N, alleviated the operating pressure of node to be upgraded, guaranteed the success rate of upgrading.
