Control module of tool management device

Abstract

The invention relates to the field of tool management modularization, in particular to a control module of a tool management device. The control module comprises an S3C2416 processor serving as a control core; a personnel library and a tool library memory being connected with the S3C2416 processor through an I2C interface; an operation log memory, connected with the S3C2416 processor through an SPI interface; an Ethernet interface, used for transmitting terminal information such as a personnel library, a tool library memory and an operation log memory to a remote server; an asynchronous serialport interface, wherein the asynchronous serial port 0, the asynchronous serial port 1, the asynchronous serial port 2 and the asynchronous serial port 3 are arranged on the S3C2416 processor and play different functions. Through using the S3C2416 processor in an ARM9 series as a control core on the whole, the processor is rich in resource, high in utilization rate, high in cost performance, small in size, light in weight, convenient to carry and install, capable of automatically scanning tools based on the RFID technology and automatically achieving tool borrowing and returning, high in accuracy and convenient to operate, and traditional manual operation is not needed.

Background technique [0002] At present, manual management is the main way of current tool management. Even if the "three counting" system mainly adopted at present, including pre-work counting, transfer counting, and post-work counting, can play a certain role, this method is more susceptible to human factors. The impact of the resulting accidents also occur from time to time. At the same time, the phenomenon of "emphasizing equipment and ignoring management" is also a common phenomenon, which is manifested in the loss of tools for no reason, and the failure to locate the responsible person.

[0002] At present, manual management is the main way of current tool management. Even if the "three counting" system mainly adopted at present, including pre-work counting, transfer counting, and post-work counting, can play a certain role, this method is more susceptible to human factors. The impact of the resulting accidents also occur from time to time

At the same time, the phenomenon of "heavy equipment, light management" is also a common phenomenon, which is manifested by the loss of tools for no reason, and the failure to locate the responsible person, etc.

In addition, due to the complexity of the product system of large enterprises and the variety of tools involved, the work of borrowing and returning tools and taking inventory of tools is very troublesome, time-consuming and laborious

Therefore, the traditional mode of relying on manual management can no longer meet the needs of high-speed development and the development needs of the new situation. It is necessary to design and develop tool management equipment based on new technology support. Among them, the design of the control module as the core component of the tool management equipment is especially important. The essential

For example, the Southwest Jiaotong University master's degree thesis "Design and Implementation of Software and Hardware for ARM-Based Tool Management Control System" published in 2018 discloses a tool management system control module design based on the STM32 development board. Control collection and reading tool label information, human-computer interaction for LCD touch screen control, etc., but some specific details have not been disclosed. For example, as an embedded system, the specific physical realization of the database has not been introduced in detail. It is still a bit cumbersome to enter the ID and password

Another example is the engineering master's degree thesis of the China Academy of Railway Sciences published in 2016 "RFID Signal-Based Maintenance Tool Management System" discloses a tool cabinet control module based on the S3C2440A processor, including a touch screen, serial port, keyboard, USB, and off-chip memory and other resources, but in order to set the Ethernet interface, it is inconvenient to upload the borrowing and returning information of the tool; another example is the master's degree thesis "Research and Development of Intelligent Toolbox Based on RFID Technology" published in 2017 by the Civil Aviation Flight Academy of China, which discloses a STC89LE52-based Intelligent toolbox control module, but this solution is a handheld device, the controller has limited performance, the number of management tools is small, and there is no personnel control function, so it is of little reference value

In addition, none of the above tool management systems considers the issue of energy saving. After the system is turned on, it is in the working state for a long time, and there is unnecessary energy waste.
