摘要：A data monitoring system includes a display unit for communicating with an operation that has charac t eristics which are to be monitored, a recording unit located remotely from the environment of the monitored operation, and a local area network interconnect circuit for connecting the display and recording units. The local area network circuit allows multiple display units to be connected to a single pair of electrical conductors. Each display unit has at least one dual microcomputer configuration interconnected by a shared dual port random access memory. A data acquisition apparatus inclu d ing two microcomputers interconnected by a shared dual access digital storage de肘关节疼痛的原因
vice, forms another aspect of the invention. One microcomputer obtains the data related to the monitored condition, stores it in the digital storage device, and modifies a status word which is monitored by the other microcomputer. When the other microcomputer detects a change in the status word, it takes the data from the shared防范意识
