20160020602 | BUS EXPLOSION PROOF NETWORK AND EXPLOSION PROOF NODE STRUCTURE THEREOF - A CAN bus explosion proof node structure is disclosed which includes a physical parameter sensor, a physical parameter measurement circuit, a master controller, a data storage module, a communication interface module, and a power voltage and current limiting module. The master controller performs service processing of the digital signals, compares them with respective threshold levels to determine whether dangerous situations occur for the explosion proof node, and sends out an alarm when dangerous situations occur for the explosion proof node. The power voltage and current limiting module limits a maximum open circuit voltage and a maximum short circuit current of input power so that explosive gas and dust will not ignite when the nodes are in normal operation or experience failures. | 01-21-2016 |
20150280304 | LOAD CELL TOPOLOGY NETWORK BASED ON MULTI-BRANCH CABLES - The present invention relates to a load cell topology network comprising at least one multi-branch cable and a plurality of load cells. Each multi-branch cable comprises at least three connectors and one or more groups of signal lines; each group of signal lines comprise at least three branch signal lines, with one end of each branch signal line connected to at least three connectors described respectively and correspondingly, and the other end of each branch signal line connected to a common node, thereby realizing the interconnection of the same kinds of electrical signals between respective connectors; each connector is adapted to be connected to another multi-branch cable or a load cell. The plurality of load cells are electrically connected by the multi-branch cable to form a topology network. | 10-01-2015 |
20150268089 | WEIGHING SYSTEM AND WEIGHING METHOD HAVING WEIGHING UNINTERRUPTED FUNCTIONS - A weighing system and a weighing method are disclosed having uninterrupted weighing functions. A plurality of load cells in the weighing system are arranged so that each load cell has a local small neighborhood, the local small neighborhood being defined by four neighboring points in front, back, left, and right of the load cell and four points on diagonal directions in a matrix. A weighing control module polls the load cells to determine whether there is failed load cell(s), and performs a calculation: | 09-24-2015 |
20150226602 | LOAD CELL WIRELESS KIT - A load cell wireless kit as disclosed can include a load cell and a kit component removably attached to an outside of the load cell. Exemplary embodiments are free of cables and a junction box, and can provide a great convenience for use and save power consumption, without affecting normal system functions. | 08-13-2015 |
