Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] The main body of the present invention is a set of CPLD-based dot-matrix material detection and reclaiming instruction method and intelligent device. CPLD is the core of the work, and realizes three functions of communication with wireless nodes, material detection, and material retrieving instructions. Serial ports can be used to communicate with wireless nodes, which is simple and efficient; material detection and material reclaiming indication are two sets of independent functions, which occupy different control pins of CPLD. The material detection unit is a dot matrix structure made of cables according to the actual size of the material rack. There is a detection device at each row and column intersection, which is used to detect the stock at each position on the material rack. The material retrieving indicator is similar to the st...

Abstract

The invention relates to a dot-matrix material detecting and fetching indicating device and method. The device comprises two functional parts: a dot-matrix material detecting unit and a dot-matrix fetching indicating device, wherein the dot-matrix material detecting unit is arranged on a detected material shelf and used for scanning the allowance of a material, giving an alarm if the material lacks and sending the alarm to a wireless node via an interface, a plurality of material racks in a storehouse form a wireless sensor network via wireless nodes, and the wireless network converges the data of each node and uploads the data to an upper layer server; the dot-matrix fetching indicating device is arranged on the material rack; when a fetching person needs to fetch a certain material, the fetching person only needs to select the material in the upper layer server and give the quantity, the server transmits a fetching instruction to the corresponding material rack via the wireless network to lighten a master pilot lamp of the material rack and a corresponding material position indicating lamp, and a digitron carried by the wireless node displays the fetching quantity. According to the device and the method, a plurality of material racks in a storehouse are connected into a wireless sensor network using mature wireless sensor network technology, and the allowance of materials on all material racks in the storehouse is monitored by the server in the office area, so that material shortage is monitored in real time.

Description

technical field [0001] The invention relates to detection technology and wireless sensor network technology, in particular to a dot-matrix material detection and reclaiming indicating device and method. Background technique [0002] In the field of equipment manufacturing, such as mechanical processing, instrumentation and other industries, there are many kinds of materials that need to be used in the production and processing process, and the daily consumption is relatively large. If the management is not good, there will often be problems affecting the production schedule due to lack of materials. Timely perception of material defects in the warehouse and timely replenishment can effectively reduce the impact of material shortage on production progress, thereby improving efficiency; The storage situation is very familiar, so that the required materials can be found in time. Once the new warehouse manager is replaced, it will take a lot of time and effort to find materials...
