For example, the user terminal 10 uploads the basic information stored in the database unit 30 to the weight calculation module 20 so that the weight calculation module 20 may calculate the wiring weight of the system based on the basic information. To help.

In addition, the user terminal 10 inputs various control commands necessary for calculating the wiring weight of the system in the weight calculation module 20, and outputs the result according to the control command, so that the user calculates the wiring weight of the system. And control the weight of the system.

The user terminal 10 may include a personal computer, a smart terminal, a personal digital assistant (PDA), and the like.

The weight calculation module 20 uploads basic information stored in the database unit 30, generates a circuit route for the weight model circuit based on the basic information, and separates circuits for each system from the generated circuit route. Then, the wiring weight in the circuit separated for each system is calculated.

2, the weight calculation module 20 includes a circuit route generation unit 21, a circuit separation unit 22, and a weight calculation unit 23.

The circuit route generation unit 21 constructs a wiring circuit route from the basic information stored in the database unit 30 according to a control command input from the user terminal 10, and the weight to be calculated from the wiring circuit route. The model sets are combined and uploaded as shown in FIG.

The weight model is separately marked in the corresponding text as shown in the text 'W001' of FIG. ) To upload.

Then, the circuit route generation unit 21 extracts the circuit route of the weight model by connecting From_Id and To_Id of the wire list from the uploaded basic information. Here, 'From_Id' and 'To_Id' are information defined for identifying systems and connecting them to each other.

Subsequently, the circuit separation unit 22 extracts a wire list composed of the weight model part numbers from the circuit route of the weight model generated by the circuit route generation unit 21 according to the control command of the user terminal 10. By doing so, circuits constituted by systems are separated.

That is, as shown in FIG. 4, the circuit separation unit 22 includes 'R-0020', for the weight model circuit of the vehicle corresponding to 'OrderNo' is W001, 'BWS' is 91890-A8010W, and corresponds to 'CONT_THETA_GDI'.

That is, the circuit separation unit 22 separates the circuit for each system using 'From_Id' and 'To_Id' of the circuit route as shown in FIG. 5.

The weight calculator 23 calculates the wiring weight of the system by the circuit separator 22.

In this case, the weight calculator 23 calculates the wiring weight of the system according to the preset weight calculation type range.

The weight calculation type range may be set according to the type of circuit connection between the systems.

Typically, the system circuit connection type includes the main system when the main system is connected to the peripheral system by an inline connector, when the main system and the plurality of peripheral systems are connected by splice joints, and when the main system is ultrasonically fused to the plurality of peripheral systems. And the peripheral system are connected by joint connectors, and the main system and the peripheral system are connected by cut joints.

Depending on the connection, it can be either the main system or the peripheral system.

Meanwhile, the weight calculator 23 calculates the wiring weight of the system according to the preset weight calculation type range for each circuit connection type. In this case, the weight calculator 23 extracts the BOM information and the connector information of the circuit connected to the system to calculate the wiring weight of the system.

In more detail, when the circuit connection type corresponds to the case where the main system is connected to the peripheral system through the inline connector as shown in FIG. 5, the weight calculator 23 performs the wiring weight from the main system to the peripheral system. To calculate.

When the circuit connection type corresponds to the case where the main system and the plurality of peripheral systems are connected by the splice joint as shown in FIG. 6, the weight calculator 23 calculates the wiring weight from the main system to the peripheral system.
