Problems solved by technology

[0002] As the bus communication becomes more and more widely used, each device on the CAN bus will have a corresponding bus target address. The target address of the existing bus is generally programmed or adjusted by peripheral dialing. In this case, it is necessary to modify the target address online. In the prior art, each device on the bus has a corresponding target address of the bus, and the device needs to be disassembled to adjust the program or peripheral dialing code, resulting in The use process is very inconvenient. For some large equipment, the process of disassembling and replacing the target address has certain potential safety hazards.

Embodiment 1

[0029] figure 1 It is a schematic diagram of a system for modifying the device target address online in the present invention; as figure 1 A system for modifying the target address of a device online is shown, including a bus, a second device communicating through the bus, and a first device for inputting the target address to be replaced, and a storage unit for storing target address information is set in the second device , the first device communicates with the second device through the bus to output the target address to be replaced in the storage unit in the second device, and the second device reads the target address to be replaced and replaces the original target address information during the startup process; The second device also includes a controller, the controller is communicatively connected to the storage unit, the first device is communicatively connected to the controller in the second device through a bus, the controller receives the target address informati...

Embodiment 2

[0039] figure 2 It is a system flowchart of a method for modifying device target address online in the present invention. Such as figure 2 The method for modifying the device target address online also includes the following steps:

[0040] S1. The first device inputs a valid target address to the second device through the bus, and the second device receives the target address and stores it in the storage unit;

[0041] S2. The second device selects the starting path to start from the storage unit, obtains the target address to be replaced inputted through the bus in the storage unit, replaces the target address with the target address of the second device, and stores the original target address information cover;

[0042] or;

[0043] S1. The second device receives the wrong target address in the controller. The controller cannot recognize the target address information through the program. The controller will send the wrong command through the bus, and the first device...

Embodiment 3

[0048] The online management method of the second device disclosed in this case also includes a host device, the host device masters all the target address information sent by the first device to each second device in the bus, and the host controls the obtained target address information through the background operation the second device exists in the management system;

[0049] Moreover, the host computer deletes the second device in the non-control system or the second device that has been screened out by the system from the system through the background operation, by deleting the target address of the second device.

[0050] The second device is controlled by the first device through the target address. The second device receives the effective address sent by the host through the first device and becomes part of the management system. After the target address in the second device has been replaced, it will enter the bus management by default. system;

[0051] Alternatively...

Abstract

The invention discloses a system for online modifying the target address of a device, comprising a bus, a second apparatus communicating through the bus, and a first apparatus for inputting a target address to be replaced. The second apparatus reads the target address to be replaced in the startup process and replaces the original target address information. The invention discloses a method for online modifying the target address of a device. The first apparatus inputs a valid target address to the second apparatus through the bus. The second apparatus receives and stores the target address ina storage unit. The device reads the target address in the startup process. The invention discloses a device online management method. A host sets an address segment, and sets the second apparatus inthe field within or outside the address segment through the first apparatus so as to manage whether the field device is present in the project management or not. According to the system and the method for online modifying the target address of a device, and the device online management method, the target address information can be replaced conveniently, the information replacing speed is effectively improved, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of long-distance communication, and more specifically, the invention relates to a system for modifying device target addresses online, a method thereof, and a device online management method. Background technique [0002] As the bus communication becomes more and more widely used, each device on the CAN bus will have a corresponding bus target address. The target address of the existing bus is generally programmed or adjusted by peripheral dialing. In this case, it is necessary to modify the target address online. In the prior art, each device on the bus has a corresponding target address of the bus, and the device needs to be disassembled to adjust the program or peripheral dialing code, resulting in The use process is very inconvenient. For some large equipment, the process of disassembling and replacing the target address has certain potential safety hazards. Contents of the invention [0003] The technical prob...
