Description

A kind of redundancy approach of tractor engine data

Technical field

The present invention relates to technical field of data processing, more particularly, to a kind of redundancy approach of tractor engine data.

Background technique

As agricultural machinery intelligence degree is higher and higher, there are tractor multiple control units to carry out to different systems Control and monitoring, tractor has ECU (control unit of engine), VCU (full-vehicle control unit), TCU (gearbox control at present Unit), ICM (instrument control module), data are exchanged by CAN bus between each control unit, and related data is stored Into respective EEPROM, but if some control unit breaks down or not in communication, it is necessary to will specifically count According to being substituted into new control unit, otherwise data can be reset.And vehicle hour and operating range etc. are to influence client Maintenance, the important information of used car trade and data, are related to main engine plants and the equity of user.

Existing technical solution is unable to automatic synchronization operation data to new control list when replacing some control unit Member, the data such as working time, range ability of tractor when manual record being needed to replace ECU, then uses relevant service work Tool is write with a brush dipped in Chinese ink in corresponding controller.And common attendant does not have the permission for writing with a brush dipped in Chinese ink data, needs to return factory, by profession Technical staff operate, maintenance cycle is long.

Be not easy to manage by manually writing with a brush dipped in Chinese ink data, be easy careless omission, and haves the shortcomings that write with a brush dipped in Chinese ink data it is random, if several Quality guarantee period, maintenance period, vehicle value etc. may be influenced whether according to inaccuracy.

Summary of the invention

In view of the defects existing in the prior art, the purpose of the present invention is to provide a kind of redundancies of tractor engine data Scheme needs manually to write with a brush dipped in Chinese ink data, and write with a brush dipped in Chinese ink data to be inconvenient to be not easy after tractor replaces some control unit for solving The shortcomings that management.

The present invention provides a kind of redundancy approach of tractor engine data, each control unit packet of the engine It includes: VCU, ECU, the TCU connected by CAN bus;The CAN bus is also connected with shelf storage ICM;

The redundancy the following steps are included:

S1: the data of each control unit are respectively stored in main memory and shelf storage,

S2: when the data appearance stored in main memory is abnormal, according to the attribute of data, spare accordingly deposits is read Data in reservoir simultaneously copy in main memory the replacement for completing data.

Further, the replacement process includes:

When the data attribute stored in the main memory is vehicle identification code, read from the shelf storage ICM Access evidence, replaces the corresponding data in the main memory VCU.

Further, the replacement process includes:

When the data attribute stored in the main memory is engine hour, read from the shelf storage ICM Access evidence, replaces the corresponding data in the main memory ECU.

Further, the replacement process includes:

When the data attribute stored in the main memory is Car-hour, read from the shelf storage ICM Data replace the corresponding data in the main memory VCU.

Further, the replacement process includes:

When the data attribute stored in the main memory is PTO hours, number is read from the shelf storage ICM According to replacing the corresponding data in the main memory VCU or TCU.

The beneficial effects of the present invention are:

The technical program is sent by primary storage controller and storing data, receives and stores data from storage control Scheme avoids the process for artificially writing with a brush dipped in Chinese ink data, will not leak brush, wrong brush data, improve data safety and reliability, efficiency are higher than Artificial brush, and data are just reliable, do not influence the interests of client and main engine plants.

Detailed description of the invention

Fig. 1 is a kind of flow diagram of the redundancy approach of tractor engine data of the invention;

Fig. 2 is main memory and CAN bus connection relationship diagram of the invention.

Specific embodiment

In being described below, for illustration and not for limitation, propose such as project equipment structure, interface, technology it The detail of class, to understand thoroughly the present invention.However, it will be clear to one skilled in the art that there is no these specific The present invention also may be implemented in the other embodiments of details.In other situations, omit to well-known device, circuit and The detailed description of method, in case unnecessary details interferes description of the invention.

As shown in Figure 1, a kind of redundancy approach of tractor engine data, each control unit packet of the engine It includes: VCU, ECU, the TCU connected by CAN bus;The CAN bus is also connected with shelf storage ICM;

The redundancy the following steps are included:

S1: the data of each control unit are respectively stored in main memory and shelf storage;

S2: when the data appearance stored in main memory is abnormal, according to the attribute of data, spare accordingly deposits is read Data in reservoir simultaneously copy in main memory the replacement for completing data.

In some illustrative embodiments, the replacement process includes:

When the data attribute stored in the main memory is vehicle identification code, read from the shelf storage ICM Access evidence, replaces the corresponding data in the main memory VCU.

Vehicle identification code is set of number, sequence number, for identification the coding of tractor vehicle.

In some illustrative embodiments, the replacement process includes:

When the data attribute stored in the main memory is engine hour, read from the shelf storage ICM Access evidence, replaces the corresponding data in the main memory ECU.

Engine hour be engine after factory, engine altogether used how long.

In some illustrative embodiments, the replacement process includes:

When the data attribute stored in the main memory is Car-hour, read from the shelf storage ICM Data replace the corresponding data in the main memory VCU.

Car-hour be tractor vehicle factory after, be used to indicate tractor vehicle altogether start how long.

In some illustrative embodiments, the replacement process includes:

When the data attribute stored in the main memory is PTO hours, number is read from the shelf storage ICM According to replacing the corresponding data in the main memory VCU or TCU.

It is used within PTO hours indicate working output shaft, for characterizing the time of vehicle power output action.

1. new spare ECU will be synchronized automatically in the case where replacing spare ECU, because specific data are total It is transmitted on line, spare ECU reads and stores it;

2. service aid needs to read specific data, and service aid from backup ECU in the case where more change owner ECU It needs to be written into main ECU with the PGN specified in this document;

3. in the case where replacing active and standby ECU at the same time, only customer service is authorized to use proprietary PGN on main ECU Specific data is written, then backup ECU is synchronized data itself by CAN bus.

In conclusion just attendant is needed to write by service aid when only master & slave control unit breaks down simultaneously Enter data, and probability of occurrence is very low the case where master-slave equipment breaks down simultaneously.Above scheme can be in most feelings The risk that human factor generates storing data can be reduced to avoid the process for manually writing with a brush dipped in Chinese ink data under condition, had safe and reliable The advantages of.

The beneficial effects of the present invention are:

The technical program is sent by primary storage controller and storing data, receives and stores data from storage control Scheme avoids the process for artificially writing with a brush dipped in Chinese ink data, will not leak brush, wrong brush data, improve data safety and reliability, efficiency are higher than Artificial brush, and data are just reliable, do not influence the interests of client and main engine plants.
