Description

Tool and Die Fixed Assets Remote Inventory System and Method

technical field

The invention relates to a technology for remote inventory of tool and mold fixed assets, in particular to a system and method for realizing remote inventory of tool and mold assets in large-scale divergent enterprises by using RFID radio frequency identification technology and Internet communication technology.

Background technique

Large-scale car manufacturers have many suppliers of car parts, among which a considerable number of suppliers, the tools and molds used in their production lines (mainly various molds, testing equipment, fixtures and other tooling) are funded and manufactured by car manufacturers. Yes, they all belong to the fixed assets of car manufacturers. Such tool and mold fixed assets are not only huge in number, but also widely distributed, usually in multiple cities. In order to ensure the integrity of these borrowed assets, car manufacturers must Arrange personnel to go to the place of use for inspection and inventory. At the same time, there are still a large number of tool and mold assets distributed in factories near car manufacturers and in factories in other places, and it is also necessary to arrange personnel to carry out inventory every year. We call this method of arranging people to go to the place where the assets are used to carry out physical inventory as the manual inventory method.

During the implementation process, we gradually found that there are certain deficiencies in the manual inventory method. The first is the high inventory cost. According to the current amount of assets, the car manufacturer dispatches 4-5 personnel every year to the company's headquarters, suppliers in various places and factories in other places for on-site inventory. foreign travel expenses. The second is the problem of low inventory accuracy. The main reason is that when manually checking the content of the asset nameplate, misreading and writing errors occur; input errors occur when the inventory data is input into the computer; due to unclear handwriting, data input personnel misread and mistype, etc., the above situations affect the inventory statistical data. accuracy and authority. The third is the problem of low efficiency. The inventory is not fast, and the daily inventory of manual inventory generally does not exceed 80 assets; sometimes it takes 1-2 days to go to the on-site storage point for a few assets; the on-site inventory records generally need to be recorded after the inventory personnel return to the company The process of inputting and counting takes as little as a day and as long as a week, and the input and analysis of inventory data also takes a certain amount of time. Therefore, it objectively affects the timeliness of statistical publication of inventory results.

An embodiment of the remote stocktaking system for fixed assets of tools and molds

Fig. 2 shows the principle of an embodiment of the tool and mold fixed asset remote inventory system of the present invention. Please refer to FIG. 2 , the system of this embodiment includes: a handheld device 1 , a remote inventory system platform 2 and an electronic nameplate 3 equipped with an RFID chip.

The handheld device 1 includes an RFID module 11 , a camera module 12 , a positioning module 13 , an automatic acquisition module 14 , a mold state input module 15 , and a data upload module 16 .

The workflow of the handset 1 is shown in FIG. 3 . The on-site staff first performs user login on the handheld, and then automatically obtains information when the label information on the electronic nameplate is readable. Specifically, the automatic acquisition module 14 controls the RFID module connected to it to read the label information on the electronic nameplate 3, controls the photographing module 12 connected to it to automatically take a panoramic photo that can reflect the whole picture of the fixed asset, and controls the positioning module 13 connected to it Automatically obtain the location information of the mold. It can be designed as a physical button for automatic acquisition, that is, the electronic nameplate label information, mold photo, and geographical location coordinates can be obtained synchronously through the physical button of the handheld device, so as to effectively prevent manual operation by personnel and prevent manual fraudulent information collection.

In the case that the label information is unreadable, the staff manually inputs the label information, and then manually calls the camera module 12 to manually license the license plate, combined with the location information automatically obtained by the positioning module 13 .

The positioning module 13 includes a GPS positioning unit 131 , a WIFI positioning unit 132 and a base station positioning unit 133 . The reason for designing three positioning methods is that the geographical locations to be collected are distributed all over the country, and the collected locations are all indoors. There will be situations such as no GPS signal, no network signal, or unstable network signal. These situations will lead to The system cannot be used normally.

The GPS positioning unit 131 uses the GPS positioning module on the mobile phone to send its own position signal to the positioning background to realize the positioning of the mobile phone. GPS is the earliest, most mature, and most widely used positioning technology, but it also has an obvious defect, that is, it cannot be positioned indoors, and the accuracy of general civilian use is not high enough, but it can meet the requirements for this system.

The WIFI positioning unit 132 automatically searches and connects to the WIFI signal when there is a WIFI signal, obtains the strength of the WIFI signal and the MAC address to comprehensively calculate the location information of the device, and its positioning error is about 24 meters.

The base station positioning unit 133 determines the position of the mobile phone by using the distance calculated by the base station to the distance of the mobile phone. The principle of base station positioning is: the mobile phone measures the downlink pilot signals of different base stations, and obtains the TOA (Time of Arrival, time of arrival) or TDOA (Time Difference of Arrival, time difference of arrival) of the downlink pilot signals of different base stations. Combined with the coordinates of the base station, the position of the mobile phone can be calculated by generally using the triangular formula estimation algorithm. When GPS positioning cannot be performed indoors, mobile phone base station positioning LBS is used to realize the positioning function, but the accuracy depends on the distribution density of base stations and the size of the coverage area. The more base stations are measured, the higher the measurement accuracy.

The positioning module 13 automatically switches between these three units to ensure the accuracy and stability of coordinate information collection. Fig. 4 shows the working flowchart of the handset acquiring the geographic location. In Fig. 4, the priority of acquiring the geographic location information in the system is GPS > WIFI > base station positioning. When location positioning is required, first turn on the GPS module (the GPS positioning error is about 10 meters) to obtain the GPS geographic location coordinates. If the GPS signal is lower than a certain threshold value, it indicates that the GPS signal has no signal or the signal is unstable. The system will switch to the wifi mode for positioning (the wifi positioning error is about 24 meters), automatically search for the connected wifi signal, and comprehensively calculate the location information of the device through the MAC address of the wifi signal and the strength of the wifi signal. If both GPS and wifi cannot be positioned successfully, the system will use the base station to achieve positioning (the base station positioning error is about 210 meters), and calculate the geographic location information of the device through the distance from the base stations around the device.

Then, through the mold state input module 15, the staff inputs the mold state including the actual usage of the asset or the condition of the asset in good condition. While the status is input, the staff can also call the photographing module 12 to take some auxiliary photos or input remark information.

So far, all the information collection work has been completed, and the collected information is uploaded to the server through the data upload module 16 .

The remote inventory system platform 2 includes an instruction issuing module 21 , a data calling module 22 , a statistical analysis module 23 and a result output module 24 .

The instruction sending module 21 is responsible for sending inventory instructions to the site when the entire system just starts running. The data calling module 22 calls the collected information from the server after the handset 1 has completed the data collection and uploaded to the server. Afterwards, the statistical analysis module 23 performs statistical analysis on the collected information. Statistical analysis functions include: statistical analysis of static data of tool and mold assets, statistical analysis of inventory plan completion, statistical analysis of scanning history records, statistical analysis of inventory results, statistical summary of supplier information, statistical summary of handheld information, etc. Finally, the result of the statistical analysis is output by the result output module 24 . Various statistical analysis results can be output in the form of reports, forming such as: "List of Fixed Assets with Accounts and Nothing", "List of Fixed Assets with Unsuitable Locations", "List of Incomplete Fixed Assets", "Summary of Inventory Results", "Handheld Machine Binding Summary Table", "Scanning History Logbook" and so on. At the same time, the system has also set up an automatic email feedback function for the inventory results, which can inform the recipient of the inventory results in a timely manner, so as to urge timely rectification.

The structural principle of the electronic nameplate 3 is shown in FIGS. 5A to 5C . The electronic nameplate 3 is composed of a label substrate 31 , an antenna printed copper skin 32 and a label chip 33 . The label chip 33 and the antenna printed copper skin 32 are connected by gold wire crimping, and the label chip 33 is covered with black glue. The antenna printed copper skin 32 is arranged on the front and back sides of the electronic nameplate 3 respectively. The label substrate 31 The FR-4 epoxy glass fiber plate is selected as the carrier for the antenna to print the copper skin and the label chip to be crimped.

The back side of the label chip 33 is provided with a longitudinal slit 34 (such as a V shape), and an adhesive 35 is pasted on the slit surface (for example, VHB strong adhesive is selected, placed on the back of the label, and pasted on the mold), so that the label chip It is easy to break when it is forcibly disassembled by external force, so that the gold wire crimping pin of the tag chip is broken and damaged, resulting in the failure of the electronic nameplate.

In other words, there are two design structures for the anti-disassembly of the electronic nameplate. The first design structure is the rivet 36, which can prevent personnel from easily warping the label. It must be cut and polished with electric tools to remove the rivet. The second design structure is the adhesive backing and the easy-to-break cut groove, which can easily break the label and make the label invalid when removed from all corners and sides around the label.
