A method of predicting failures of data storage devices in a data storage network. In predicting failures, birth and/or health records of data storage devices in the data storage network are requested. The records are then scaled and thresholded and processed using a probabilistic neural network to classify the data storage devices. Based on the classification, an action is taken to improve the reliability and availability of the data storage network.

A method of controlling an inverter, in which the inverter includes a single-phase inverter arrangement comprising a complementary pair of power switches, comprises the steps of:

controlling the complementary pair of power switches with a modulating signal to output an AC signal;

judging which of the power switches in the complementary pair of power switches is at a higher temperature;

determining the magnitude and sign of a DC offset signal to apply to the modulating signal to reduce the total current in the power switch judged to be at the higher temperature; and

applying the DC offset signal to the modulating signal.

The invention provides a fault detection method and device and related equipment. The fault detection method is applied to a network card or a switch, and comprises the steps: generating a heartbeat detection message; sending the heartbeat detection message to a service node, wherein the heartbeat detection message is used for detecting the working state of the service node, and the service node is a node where the network card is located or a service node connected with the switch; obtaining a response message, wherein the response message comprises state information used for indicating the working state of the service node; and sending the response message to a management node, wherein the management node is used for managing the service node. Therefore, the performance of the distributed system is improved.

A dual-channel hot standby system and a method for carrying out dual-channel hot standby, the system comprises a hot standby status management layer including two hot standby management units, an application processing layer including two application processors, and a data communication layer including two communicators; the hot standby status management layer is used for controlling the setting and switching between a active status and a standby status of the two application processors, monitoring the working status of the data communication layer, and carrying out synchronization of the control cycles for the two channels of the system; wherein one of the hot standby management units controls one of the application processors, and together constitute a channel of the system therewith; the data communication layer is used for receiving data from outside, and forwarding the data to the application processing layer. The present invention avoids the occurrence of “dual-channel-active” or “dual-channel-standby” status; ensures synchronization of the control cycles of two channels; reduces the time of the system for responding to breakdowns; meets the real-time requirements; enhances the reliability and availability of the system; and ensures a seamless switching between active and standby statuses.

The system and the method provided by the invention have the advantage that the reliable automatic driving is realized.

The invention relates to a gate for rail transit. The gate comprises a plurality of gate case bodies arranged side by side; each gate case body is provided with a controller and an infrared sensor; the gate further comprises an abnormal execution mechanism connected with the controller; a light curtain device is arranged at one side of each gate case body; and the light curtain devices form a visible light curtain wall between every two adjacent gate case bodies. According to the gate for rail transit of the invention, mechanical opening and closing actions are greatly reduced; a blocking effect can still be achieved visually; the occurrence of behaviors such as ticket evasion is prevented through the abnormal execution mechanism; and therefore, the gate has greatly-improved reliability and usability compared with the prior art. The actions of mechanical parts of the gate are reduced largely, and therefore, the service life of the gate is prolonged, and the maintenance cost of the gateis also remarkably reduced.
