The positioning card can define a variety of different states according to the sound and light. Each state can represent different meanings of the item, such as missing parts, waiting for maintenance, under maintenance, and already maintained. It can also mean other meanings.
2. System design
2.1. Design principle
First, according to the specific conditions of the warehouse area, a certain number of card reader base stations are placed to make the signal in the warehouse area fully covered.
Bind a RW-T738 sound and light search to the stored itemselectronic label, When the warehousing is completed, the items and the positioning card are placed within the signal coverage of the base station. The card reader base station receives the information of the positioning card and uploads it to the transmission interface, and the transmission interface uploads to the host. The host is processed by software to obtain The specific location information of the item, the area location of the item can be displayed on the host map when positioning, combined with the sound and light prompt of the positioning card, the item can be found accurately and conveniently.
After the item is bound to the location card and stored in the warehouse, the information is uploaded to the system through the card reader base station, and the item information is displayed in the item information column in the item management, which can be based on the area of the item, item number, location card number, status, storage time, etc. Make an inquiry.
The indicator light of the positioning card and the sound of the buzzer have four states, which can indicate the four different states of the item. They are: missing parts-the red light flashes four times and the buzzer beeps four times, to be maintained- The red light of the location card flashes once, and the buzzer sounds once. During maintenance-the red and green lights of the location card flash twice, the buzzer sounds twice, and it is maintained-the green light flashes three times and the buzzer sounds three times. Press the button on the positioning card for a short time for about 1 second to view the current status of the item, press the button on the positioning card for a long time for more than 3 seconds to switch between the four states. The system will record the status change every time the status is changed, thereby forming a status record, which is convenient for tracking and querying.
The system has the function of automatically counting various types of items. The positioning card enters the item number, positioning card number, item type, and item description when entering the warehouse. The information is uploaded to the transmission interface through the card reader base station, and the transmission interface is uploaded to the host. The host analyzes and counts. Calculate the quantity of each type and complete the inventory of the inventory items.
Item outbound statistics can record item number, item type, in-warehousing time, out-of-warehouse time, whereabouts and other information. The item number, item type, in-warehouse time, and out-of-warehouse time are automatically generated by the system at the time of outgoing, and the destination needs customers The choice is made, and the choice of whereabouts is the information entered in advance by the customer.
