Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; the two elements may be directly connected or indirectly connected through an intermediate medium, or may be communicated with each other inside the two elements, or may be wirelessly connected or wired connected. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the invention discloses a remote upgrade detection method for roadside parking equipment, which comprises the following steps of:
step S101, when the parking equipment detects that the version of the parking program is updated, the parking equipment remotely downloads an upgrade file; the upgrade file is composed of a plurality of encrypted differential files, and each encrypted differential file comprises an encrypted header and upgrade content;
and S102, remotely upgrading the parking equipment according to the upgrading file.
It should be noted that, the method for detecting remote upgrade of the roadside parking equipment disclosed by the embodiment of the invention includes: when the parking equipment detects that the parking program version is updated, the parking equipment remotely downloads the upgrade file; the upgrade file is composed of a plurality of encrypted differential files, and each encrypted differential file comprises an encrypted header and upgrade content; and according to the upgrading file, remotely upgrading the parking equipment. Compared with the prior art, the invention is convenient for remote upgrading of the roadside parking equipment.
It should also be noted that the parking facility is divided into two zones, a first zone and a second zone. The program is defaulted to run in one partition, and when the program enters the upgrading process, the upgrading file is programmed in the second partition. When the upgrade is complete, the program jumps to the two-partition execution. When the program operated by the two partitions detects the upgrade, the upgrade file is programmed in one partition, and when the upgrade is completed, the program jumps to the other partition for execution. If the upgrade fails, the program is not adjusted and still runs in the current partition. Therefore, upgrading failure caused by abnormal reasons during upgrading is guaranteed, and normal operation of equipment can be guaranteed.
In a specific implementation process, before step S101, as shown in fig. 2, the method further includes: and S100, when the parking equipment senses that the vehicle leaves the field, the parking equipment is connected with a remote server for network communication.
In a specific implementation process, the encryption header is 16 bytes of data, and the data includes a current version number, a last version number supporting upgrading, a corresponding device model, a file length, a current file CRC (cyclic redundancy check) checksum, a whole upgrading identifier, a current differential packet number and a total file checksum.
In a specific implementation process, the upgrade content is a difference file formed by recording different positions and contents of the current version binary upgrade file and the previous version binary upgrade file.
In a specific implementation process, when the size of the differential file is smaller than that of the upgrade file before the differential file is not encrypted, the whole upgrade identifier is not effective. And the device software analyzes the content of the second part of differential file, and writes the content of different positions into the flash address of the device, thereby completing upgrading.
In a specific implementation process, when the size of the differential file exceeds the size of the upgrade file before differential encryption, the whole upgrade identifier takes effect. And burning all contents except the encrypted header part into the flash address of the device according to the position corresponding to the differential packet number.
In the specific implementation process, each differential file is numbered in an increasing mode according to the content sequence, and the file names are named according to the time of the timestamp millisecond, so that all differential packets are unique.
In the specific implementation process, each liter of level completes one differential packet, and the parking equipment automatically records the name, the number and the checksum of the differential packet into flash storage.
In the specific implementation process, when the number of the recorded upgraded differential packets is consistent with the total number, and the checksum sum of all the differential packets is equal to the total checksum, the upgrade is completed.
In the specific implementation process, when the parking equipment is abnormally powered off, the parking equipment is restarted after the upgrading is failed, and the equipment detects the upgrading again, the upgraded file is not downloaded by the equipment.
It should be noted that, the upgrade file is an encrypted differential file, which can greatly reduce the size of the upgrade file. When the upgrade file is large, the device may perform a segmented download. If the downloading fails due to network reasons in the downloading process, the downloaded upgrade complete upgrade package can be kept and recorded, and all upgrade files do not need to be downloaded again when the upgrade is performed again. And after the downloading is successful, the software is automatically updated in the equipment. If the equipment is powered off due to external factors in the updating process, after the equipment is powered on and restarted, the software can automatically recover to be normal and enter upgrading again.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
