Distributed system multilevel fault tolerance method under cloud environment

The invention provides a distributed system multilevel fault tolerance method under a cloud environment, which comprises a distributed application collaboration algorithm based on a virtual machine disk snapshot, which can back up the I/O state and the dependent operating system environment; a hierarchical fault detection and recovery mechanism, which can detect a physical layer, a virtual layer, a cloud platform layer, a virtual machine OS layer and an application layer fault in real time, and adopt the matched fault recovery method for different faults. Thus, the fault detection and recovery can be refined to modules, and the strategy of top-down stepwise recovery is adopted to minimize the recovery overhead; based on the virtual fault tolerance cluster service deployment strategy of the template, a user can use the virtual machine template to perform one-click deployment on the virtual machine fault tolerance cluster and upload the operation to perform collocation, and use the authorized fault-tolerant PaaS service. The invention can effectively solve the problems that the existing cluster deployment is complicated and the fault tolerance overhead is expensive, and can cope with the distributed application fault at all levels under the cloud computing environment in all directions.

Docking station for mounting and programming multifunction timer device and method

A multifunction timer device provides a time / date stamp on a dispensing container and includes a housing, a controller with a timer circuit contained in the housing, a display for displaying information from the timer circuit, and a multifunction input button. The input button is operable in predetermined sequences to select operating and display modes of the timer device. The input button can be operated to display an actual date or time, to display a current timer value, to select between count-up and count-down modes, and to increment a counter. An adhesive backing is provided for attaching the timer device to the container. A communications link is provided for interfacing the controller with an external programmer. A reset trigger is used to automatically reset the timer device when the object is moved in a particular way, such as when a lid is removed from a pill container. A docking station interconnected with a host data processing system encodes information read from a container label and writes scanned and stored data to the timer device while simultaneously mounting the timer device to the container.

Smartphone-based HART (highway addressable remote transducer) handheld operator and implementation method thereof

The invention relates to a smartphone-based HART (highway addressable remote transducer) handheld operator and an implementation method thereof. The smartphone-based HART handheld operator comprises a smartphone with a smart operating system, a storage card with HART configuration software, and an HART wireless communication interface with a wireless communication function. The storage card is disposed in the smartphone. The smartphone is communicated with the HART wireless communication interface by means of WIFI (wireless-fidelity). The HART wireless communication interface is communicated with HART field devices through standard HART communication protocol. A user can communicate with HART field instruments conveniently with the smartphone which is widely popularized, and accordingly the handheld operator has the advantages of flexibility, portability, practicality, high cost performance and the like. A complete HART master station data link layer is built in the wireless communication face, so that the handheld operator is compatible with all HART field devices. Universal handheld operators meeting various fieldbus standards can be assembled flexibly and conveniently by changing different wireless communication interfaces.

DDR3 arbitration controller and method for high-speed ccd data storage

DDR3 arbitration controller and method for high-speed CCD data storage. A DDR3 arbitration controller of the present invention includes a read-write control module, a DDR3 arbitration module, an IP core control module, a data format replacement module, and a read-write storage module. The IP core control module is mainly responsible for driving the read-write storage module, so that the read-write storage module can read and write data correctly. The read-write storage module is responsible for matching the data stream given by the front-end with the read-write speed of the read-write storage module. The read-write speed of the read-write storage module is much faster than the front-end data stream and the data stream required by the subsequent circuit, so data is written to read and write The memory module and the data read from the read-write memory module must be speed-matched. The arbitration module is responsible for arbitrating the order of applications when multiple data streams apply for the use of the read-write storage module, determining the response order, and allocating resources for the use of the read-write storage module. The data format conversion module is responsible for converting the data format read from the read-write storage module into the standard format required by subsequent modules.
