1) It cannot be used for the setting of the work site, and the parameters often need to be set in advance.

2) The set parameters cannot establish a corresponding relationship with the monitoring parameters of the system in real time, and manual configuration is still required in use.

3) The configuration and input of parameters are randomly added, and there are often many input situations with different names but the same parameter.

Contents of the invention

The purpose of the present invention is to overcome above-mentioned defect, provide a kind of configuration input method for vehicle-mounted system fault dictionary, can automatically detect the repetitive parameter in the fault dictionary, real-time, on-line the working process of vehicle is configured and monitored, improve input efficiency and Automation, and monitoring system compatibility, openness and flexibility.

In order to achieve the above object, a kind of configuration input method for vehicle-mounted system failure dictionary provided by the present invention includes setting report display module, file configuration module, coding module and configuration information database, also includes setting input configuration module, and the method includes as follows step:

Step 1 Initialize the system, start the configuration information database, call the report display module, and display the input status;

Step 2 Start the input configuration module to query the input fault dictionary name code;

Step 3 Determine whether a fault code is required, if yes, go to the next step, if not, go to step 7;

Step 4 Call the fault code configuration parameters in the configuration information database, read the configuration file, and judge whether there is a fault code name, if so, call the coding module, verify the fault code and store it in the configuration information database; otherwise, go to the next step;

Step 5 Update the input configuration module;

Step 6 Enter the new fault code configuration parameters and fault dictionary name and store them in the configuration information database, go to step 9;

Step 7 Read the configuration file and query the configuration information database;

Step 8 monitor display;

Step 9 Determine whether to continue configuring input, if yes, go to step 3; if not, go to the next step;

Step 10 ends.

The present invention is a configuration input method for a vehicle system fault dictionary, wherein the fault coding feature parameters set by the input configuration module at least include name, dimension, value range and positioning parameters, wherein the positioning parameters include The object length and pointer ID in the location.

The advantages and positive effects of a configuration input method for vehicle-mounted system fault dictionary of the present invention are: due to the method of parameter configuration file, after the parameter information is imported into the data interface, the repeated parameters in the fault dictionary can be automatically detected, and real-time , Configure and monitor the working process of the vehicle online, which improves the input efficiency and automation, as well as the compatibility, openness and flexibility of the monitoring system, and better adapts to the future needs of the vehicle monitoring system.

The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments.

detailed description

The invention is a configuration input method for a vehicle-mounted system fault dictionary. In the input of the fault dictionary, a unique number is defined to distinguish different faults. For the same parameter object, a plurality of characteristic parameter attributes can be used to describe, and adopt Implementation of logical operation methods. Setting the same monitoring flag for the input code can make real-time monitoring information associated with specific parameters. A common input format is defined, and a large number of parameters can be pre-set as data interface files, and finally imported into the software system at the same time.

As shown in Figure 1, in a kind of configuration input method that is used for vehicle-mounted system fault dictionary of the present invention, the structure that module is set is as follows: report display module, input configuration module, configuration information database, verification module, file configuration module, parameter The configuration module and the coding module are composed.

The characteristic parameter attributes can be configured in the input configuration module, including name, dimension, value range and positioning parameters, wherein the positioning parameters include the object length and pointer ID used to determine the position in the bus. The parameters generated on this interface can be directly called in other system interfaces, realizing modular management, that is, separating parameter configuration from parameter calling.

The specific method is as follows.

As shown in Figure 2, a kind of configuration input method for vehicle-mounted system fault dictionary, this method comprises the following steps:

Step 1 Initialize the system, start the configuration information database, call the report display module, and display the input status;

Step 2 Start the input configuration module to query the input fault dictionary name code;

Step 3 Determine whether a fault code is required, if yes, go to the next step, if not, go to step 7;

Step 4 Call the fault code configuration parameters in the configuration information database, read the configuration file, and judge whether there is a fault code name, if so, call the coding module, verify the fault code and store it in the configuration information database; otherwise, go to the next step;

Step 5 Update the input configuration module;

Step 6 Enter the new fault code configuration parameters and fault dictionary name and store them in the configuration information database, go to step 9;

Step 7 Read the configuration file and query the configuration information database;

Step 8 monitor display;

Step 9 Determine whether to continue configuring input, if yes, go to step 3; if not, go to the next step;

Step 10 ends.

During the monitoring process, by calling the associated object length, pointer ID, conversion formula and other attributes in the characteristic parameter attributes, the bus value is converted into a meaningful parameter value display in real time.

The above-mentioned embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention.
