The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the scheme, in order to realize the functions of online updating and upgrading of the measuring nipple, a controller is added on the measuring nipple, and the functions of information reading and writing, updating and upgrading of application programs and the like are realized through control; for example, the controller may be configured with a read unit, an update unit, an address read-write unit, etc., to meet the hardware configuration requirements for online update and upgrade of the measurement nipple.
In this scheme, in order to guarantee that data can not lose because of losing the power, this scheme has set up memory module independent of measuring nipple joint, through memory module storage measuring nipple joint's local address information, application program update sign and parameter information's data information.
Specifically, the controller configured on the hardware design of the measuring nipple in the scheme adopts an Atmega128 single-chip microcomputer, and the controller can be used as a signal acquisition unit to acquire signals of the accelerometer through an external analog-to-digital conversion chip, so that the function of measuring nipple data acquisition is realized. In the scheme, a storage module adopts a charged erasable programmable read-Only Memory (EEPROM), parameter information is configured in the EEPROM, and a reset signal end of a controller is connected with an externally arranged hardware watchdog circuit; the controller performs data communication with the outside through a 485 interface, so that the update and upgrade control of the measurement nipple is realized.
In the scheme, the program area of an internal FLASH memory (FLASH) of the Atmega128 single-chip microcomputer can be divided into two parts: a boot program and an application program.
The guiding program distributes different local addresses of the measuring short sections so as to facilitate on-line upgrading and distinguishing different measuring short sections. The bootstrap program decides whether to erase the application program and write the updated program code according to the status flag. And receiving a corresponding system upgrading command of the 485 interface, completing corresponding system upgrading operation, and finally completing the upgrading of the application program. After the upgrade is completed, the bootstrap program exits to jump to the new application program.
The application program is a finally executed code and completes the functions of sensor data acquisition, transmission and the like of the measuring nipple. Meanwhile, a corresponding system upgrade preparation operation command of the 485 interface can be received, and a corresponding new system upgrade preparation operation is completed. The application program then resets to begin executing the boot program.
As shown in fig. 1, the scheme can firstly allocate different local address information for the measuring nipple, so as to realize the read-write operation of the addresses of different measuring nipples. Therefore, the scheme needs to judge whether an address command for writing the measuring nipple is received, if so, the local address information writing operation of the measuring nipple is executed; and judging whether an address command for reading the measuring nipple is received, if so, executing a local address information reading operation of the measuring nipple, thereby determining whether the local address of the measuring nipple is successfully written into the measuring nipple.
Further, when updating is realized, the method firstly acquires the local address information of the measuring nipple and an application program updating mark for indicating that the measuring nipple is in a state to be updated; judging whether the address information contained in the application program update command is the same as the local address information; if yes, updating the application program of the measuring nipple according to the application program updating command; if not, directly jumping to execute the current application program of the measuring nipple.
The scheme can save the update configuration time of the measuring nipple, reduce the update difficulty and effectively solve the problem of online update of the measuring nipple.
The present application will be further described with reference to the accompanying drawings.
After the measurement nipple is configured according to the mode, the configured and compiled guide program needs to be programmed into a program storage area inside the Atmega128 singlechip. After the power-on reset of the Atmega128 singlechip, the boot program is firstly entered. And reading an application program update mark stored in an appointed address of the external EEPROM, and judging whether the application program needs to be updated. The execution application is directly jumped without updating the application. And if the application program needs to be updated, the Atmega128 singlechip waits for an online upgrade command of the application program of the 485 interface to perform corresponding online upgrade operation.
In order to facilitate online upgrading and distinguishing between different measuring sub sections, different addresses are allocated to the different measuring sub sections. And receiving a write/read measurement nipple address command of 485 interfaces, and writing/reading the addresses of different measurement nipples. In the EEPROM appointed address with the address stored outside, the data is not lost when power is lost.
In this embodiment, the bootstrap program receives the corresponding system upgrade command of 485 interface, completes the corresponding system upgrade operation, and finally completes the upgrade of the application program. The boot program then jumps to the new application program and executes the new application program. As shown in fig. 2, the specific implementation manner is as follows:

In this embodiment, the application program receives a system upgrade preparation operation command corresponding to the 485 interface, and completes a corresponding system upgrade preparation operation. The application program then resets to begin executing the boot program. And the address command of the 485 interface for writing/reading the measuring nipple can be received, and the contents of the EEPROM designated addresses stored outside the different measuring nipples are written/read.
