Wireless data transmission device for molecular sieve purifier based on WBee

Abstract

The invention relates to a wireless data transmission device for a molecular sieve purifier based on WBee and belongs to the technical field of an air separation oxygen generating device. The wireless data transmission device is characterized in that a field inspection instrument is connected with a WBee terminal device, if the field detection instrument output is analog quantity, the field detection instrument and an analog-digital converter are connected with the WBee terminal device in series, and field collection data can be transmitted through a wireless data mode by the WBee terminal device; the WBee terminal device is connected with a WBee router device through a wireless way to form subnetworks of field data collection; each subnetwork is connected with a WBee coordinator through the WBee router device by the wireless way to form a field data collection network; and the WBee coordinator is connected with a gateway device, and the WBee data network is converted into a control system network format of the molecular sieve purifier. The wireless data transmission device has the advantages that the field data can be collected and transmitted in real time and sent to a control system of the molecular sieve purifier by the wireless data transmission device, and the wireless data transmission device provides data basis for the steady operation of the molecular sieve purifier and lays a reliable foundation for guarantee of product quality and safety production.

Description

technical field [0001] The invention belongs to the technical field of air separation and oxygen production equipment, and relates to an improvement to a data transmission device of a molecular sieve purifier. Background technique [0002] In modern air separation and oxygen production equipment, molecular sieve purifiers are mainly used to purify water, carbon dioxide, acetylene and other hydrocarbons in the raw air, as well as solid impurities such as dust. The molecular sieve purifier is composed of two molecular sieves, one is in the state of adsorption, the other is in the state of regeneration, and the two molecular sieves are switched in turn to purify the raw air. The switching time should be determined according to the physical characteristics of the molecular sieve, combined with the air quality of the raw material; the temperature and pressure of the molecular sieve inlet; the water and carbon dioxide content of the molecular sieve outlet; Due to difficulties and...
