In-hospital consumable delivery device based on real-time positioning method

Abstract

The invention relates to the technical field of logistics distribution positioning, and discloses a hospital consumable distribution device based on a real-time positioning method, and the device comprises the steps: collecting position fingerprints in a hospital, and carrying out the clustering of the collected position fingerprints through a k-means method; performing Hamming distance matching on the position fingerprint of the to-be-positioned device and the position fingerprints in the sub-regions, and taking the sub-regions of which the matching results are within a preset distance threshold as a region set in which the to-be-positioned device is possibly located; calculating a Gaussian logarithm distance between the position fingerprint of the to-be-positioned device and the position fingerprint in each possible area; and calculating the membership degree of each possible area, and taking the position vector mean value of the position fingerprints in the area with the minimum membership degree as the position of the to-be-positioned equipment. According to the invention, the internal fingerprint map of the hospital is determined by using the wireless network technology, position fingerprint matching is carried out on the to-be-positioned consumables, the position vector mean value of the optimal position fingerprint obtained through matching is the position of the to-be-positioned consumables, and real-time positioning of the consumables in the hospital is realized.

Description

Technical field [0001] The present invention relates to the technical field of logistics distribution positioning, in particular to a real-time positioning method based on the in-hospital consumables distribution device. Background [0002] At present, the hospitals generally only record the accounts for the management of the circulation of consumables in the hospital, and the support for the logistics management of consumables distribution is weak, especially for the monitoring of the delivery trajectory of consumables, where the consumables are sent, when can they be sent to pharmacies or departments, and cannot get a clear answer. [0003] At present, most of the indoor positioning technology is to achieve positioning through the indoor wireless sensing network, and the construction of the wireless sensing network requires a large number of sensor equipment, and in order to weaken the impact of the indoor environment and achieve high-precision positioning requirements, it is u...

Problems solved by technology

[0002] At present, hospitals generally only record accounts in the management of consumables circulation in the hospital, and support the logistics management of consumables distribution is weak, especially for the monitoring of the delivery track of consumables, where are the consumables sent, and when can they be delivered? Sent to the pharmacy or department, can not give a clear answer

[0003] At present, most indoor positioning technologies use indoor wireless sensor networks to achieve positioning, but the construction of wireless sensor networks requires a large number of sensor devices, and in order to reduce the impact of the indoor environment and achieve high-precision positioning requirements, other devices are usually required Signal auxiliary processing equipment, which leads to high investment cost of this type of positioning technology in practical applications, and does not have the value of promotion
