Abstract

The invention discloses a method for updating a multilevel system program in a lead-acid storage battery inner formation busbar type charge/discharge motor unit network. The method is capable of performing batch updating on all or part of units and also capable of updating a second-level loop control board and a third-level system man-machine interface control board of the next level of the control board. When the control board is updated, the updating is finished according to an IAP updating process; and when a display board is updated, a display board code is disguised as a user configuration program and downloaded to a residual space of an external Flash of the control board, then updating information is pushed to the display board, and the display board finishes the updating according to the IAP updating process. When being updated, a second-level system still can continue to run without influence, so that the trouble of large-scale manual downloads can be avoided and the manpower resources of enterprises can be optimized and saved. A charge unit with a huge networking scale and numerous loops can perform batch updating for part or all of control boards and display boards according to an actual situation, so that the manual intervention is avoided and the manpower cost is reduced.

Description

Lead-acid accumulator is internalized into the multilevel system method for updating program in bus-type charge-discharge machine group network

Technical field

The present invention relates to the method being internalized into a kind of user program renewal in bus-type charge-discharge machine group network at lead-acid accumulator.

Background technology

Can use on a large scale in lead-acid storage battery production factory and be internalized into bus-type charge-discharge machine, after networking, network connection diagram is shown in Fig. 1, large-scale controller utilizes RS485 fieldbus mode to carry out networking, and then is turned in USB interface access monitoring computer by RS485.

For conventional 6A fill/10A puts the charging set in 48 loops, can reach 4800 feeder numbers, substantial amounts after 100 charging set networkings, Fig. 2 is shown in by communication network connected system block diagram.Now utilize IAP (in-service units) downloading mode can only download to the control panel in each loop of level two with PC host computer, and the display board of the third level can only utilize ISP (in-system programming) mode, manual intervention is adopted to download, the danger of its workload and hot line job is all sizable.And if not hot line job, then rack can only be out of service, and line production efficiency is produced in impact.

Summary of the invention

The invention provides a kind of lead-acid accumulator and be internalized into multilevel system method for updating program in bus-type charge-discharge machine group network, multistage reception and registration can be realized, do not affect middle transition level system and normally run, reduce the system shutdown time.

Technical scheme of the present invention is as follows:

Lead-acid accumulator is internalized into the multilevel system method for updating program in bus-type charge-discharge machine group network, comprises the following steps:

(1) host computer selects the scope of renewal according to address, or sends update content to broadcast Group transmit mode to all slave computers;

(2) whether the method that control panel uses poll to detect detects in upper machine communication has the renewal sending out this address to push, namely output is closed if having, after system is in a safe condition, the renewal zone bit of power down conservation zone is write 1, then watchdog reset is used to restart system, start after reset to enter BOOTLOADER boot, IAP is started working;

(3) utilize the remaining space of Flash external in every block control panel as terminal, the configurator that disguised oneself as by program of lower computer is put in terminal, then lastest imformation is pushed to control panel as host computer, lastest imformation is pushed to display board, and the flow process that display board upgrades according to IAP again completes renewal.

Advantageous Effects of the present invention is:

1, adopt the technology of the present invention can realize multilevel system Simulation with I AP mode to upgrade, there is no too many manual intervention.Procedural compliance, program are leaked down, upgrade in the problems such as efficiency and all have greatly improved.

2, during down loading updating, if not system program at the corresponding levels upgrades, no person does not all affect upper level system and runs normally.

3, the configuration file space that the outer power down of user's sheet is preserved all has unnecessary space, does not take MCU own resources after utilizing this space.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.

The present invention is the method that a kind of user program being internalized into bus-type charge-discharge machine unit (hereinafter referred to as charging unit) at lead-acid accumulator upgrades.Specific practice of the present invention is as follows:

Have sound IAP system in original system for the renewal of control panel program, host computer can select the scope of renewal according to address, also can broadcast Group transmit mode (single work communication) and send update content to all slave computers.The process flow diagram of its logical process is shown in Fig. 3.Whether the method that first control panel can use poll to detect has the renewal sending out this address to push to detect in upper machine communication, namely output is closed if having, after system is in a safe condition, the renewal zone bit of power down conservation zone is write 1, then watchdog reset is used to restart system, start to enter BOOTLOADER boot after so resetting, make IAP start working like this.

The allocation of space figure in the FLASH region of control panel MCU is shown in Fig. 4, as can be seen here MCU can only have 64KB, wherein 4K is used for depositing the BOOTLOAD program containing IAP, only remaining 60KB deposits user program, so resource is valuable, be not suitable for dividing the terminal of a part of space as next stage system update again.In every block control panel, all can have one piece of external FlashMX25L4006E, this FLASH is originally and preserves user configurator for power down, and communication modes is shown in Fig. 5.MX25L4006E not only cost performance is high, and memory capacity has 512KB, normal setup procedure only needs 8KB, and the allocation of space figure of external FLASH is shown in Fig. 6, the present invention utilizes the remaining space of 0x00010000-0x0007F000 as terminal, solves the problem of insufficient space.

The process flow diagram of the reception display board control program of control panel is shown in Fig. 7.The configurator that disguised oneself as by program of lower computer is put in terminal, then pushes lastest imformation to control panel as PC host computer, lastest imformation is pushed to display board.The last flow process upgraded according to IAP again of display board completes renewal.

In sum, use the present invention can select to carry out batch updating to all or part of unit, also can upgrade to secondary circuit control panel and at the three-level system man-machine interface display board of control panel next stage, when upgrading display board, the user's configurator that disguised oneself as by display board code downloads on control panel (the outer Flash of sheet of middle transition level), then the program that IAP upgrades next stage is enabled, it is unaffected that level two can continue operation, the loaded down with trivial details of extensive artificial download can be avoided, optimize and save the human resources of enterprise.Huge for Interconnection Scale, the charging unit of loop One's name is legion, can carry out batch updating according to actual conditions for some or all of control panel and display board, exempts manual intervention, saves human cost.

Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, all should think and be included within protection scope of the present invention.
