Description

Inventory management setting system

The invention relates to an electronic digital data processing system, in particular to an inventory management setting system.

Manufacturers of servo systems perform functional adjustments on several components of the servo system, such as backplanes, chassis, chassis fans, heat sinks, etc., according to customer specifications, and produce a number of motherboards for installation. In the servo system. For example, if the specifications of the two batches of motherboards are different only when the chassis fans are respectively operated in a first speed interval and a second speed interval, a batch of motherboards whose chassis fans operate in the first speed interval form an inventory. A stock keeping unit (SKU), and another batch of motherboards whose chassis fan operates in the second speed range constitutes a different inventory management unit. Therefore, the manufacturer of the servo system needs to implement the above two batches of hosts. The two inventory management units respectively formed by the boards respectively establish two sets of inventory management parameter codes, and each set of inventory management parameter codes includes, for example, an inventory management number (SKU ID), a fan control table (fan table), and a chassis code (chassis ID). )and many more.

Referring to FIG. 1, the existing motherboard includes a south bridge having a general-purpose input/output (Gerneral Purpose I/O, GPIO) control circuit 13. 11. A baseboard management controller (BMC) 12 electrically connected to the south bridge 11 and controlling the servo component, and a basic input electrically connected to the south bridge 11 and communicating with the baseboard management controller 12 through the south bridge 11 The output unit (Basic Input/Output System, BIOS) 14 assumes that the N types of motherboards required by a certain customer form a total of N inventory management units, and the basic input and output unit 14 in each motherboard of the same customer. And the read-only memory of the baseboard management controller 12 pre-stores N sets of inventory management parameter codes, and the N sets of inventory management parameter codes respectively correspond to N inventory management units, and when the basic input/output unit 14 executes the booting process, the basic input The output unit 14 receives the data designation signal generated by the universal input/output control circuit 13 indicating the corresponding specification of the motherboard, that is, reads the corresponding inventory management parameter code from the read-only memory, and displays the corresponding inventory management. The parameter code is known to the user.

After the basic input/output unit 14 waits for a predetermined time (the preset time is the time required for the substrate management controller 12 to complete initialization), an instruction is sent to the baseboard management controller 12 via the south bridge 11 to indicate the The substrate management controller 12 reads the corresponding inventory management parameter code, so that the baseboard management controller 12 can control the servo component according to the read inventory management parameter code to complete the booting process.

However, the disadvantages of the motherboard in batch management are as follows.

First, when the customer adds different specifications to the motherboard, the (N+1)th inventory management unit is extended. At this time, the basic input/output unit 14 and the baseboard management controller 12 must be re-created, and the personnel are manually The corresponding inventory management parameter code is written to the basic input/output unit 14 and the read-only memory of the baseboard management controller 12. However, the operator often wants to digest the motherboard that is not shipped in the inventory. At this time, it takes extra manpower to set the data designation signal, and verify and test whether the basic input/output unit 14 and the substrate management controller 12 read the corresponding inventory. Management parameter code.

Second, because the substrate management controller 12 is initialized for 40 seconds to 60 seconds, waiting for its initialization to complete and then receiving the instruction to read which inventory management parameter code, not only the overall boot process takes a long time, but also the substrate management. The controller 12 may not even complete the boot process normally.
