Abstract: A risk assessing and managing system for monitoring and managing one or more areas includes an obtaining module, a configuring module, a calculating module, and a managing module. The obtaining module obtains parameters of an area. The configuring module configures a weight coefficient and an evaluation class value to each of several monitoring terminals or sensors according to the parameters and influence proportion of each terminal. The calculating module calculates a weight value of each terminal according to the weight coefficients, and calculates a risk value of the area according to the weight values, the evaluation class values, and readings taken by the monitoring terminals. The managing module determines a risk class of the area according to the risk value and selects an improvement program to manage the area according to the risk class. A risk warning and managing method is also provided.

Abstract: A management device includes a first server, a first control module, a management module connected to the first control module through the first server; and a first executing module connected to the first control module. When the first server is operating normally, the first server outputs a first signal to the first control module, the first control module controls the first executing module to operate corresponding to the first signal. When the first server is operating abnormally, the management module outputs a second signal, the first control module controls the first executing module to operate corresponding to the second signal.

A container data center is further disclosed.

Abstract: A control system for a mobile warning triangle, to implement route planning by distance sensors and internet connection. Modules can control the mobile warning triangle to rotate to establish an environmental map and convert the environmental map into a linear vector map. A line forward can be established as a reference direction and the mobile warning triangle moved a second predetermined distance. A driving control module controls the mobile warning triangle to keep moving forward on the original line or to move on a reselected line. A control method of the mobile warning triangle is also provided.

Abstract: A mounting mechanism which can be mounted to holes with different shapes includes an installation member, a locating member, and a clamping member. The locating member includes a first locating pillar with one end fixed to the installation member and a second locating pillar fixed to an opposite end of the first locating pillar. A floating pillar is sheathed on the second locating pillar and one end of the floating pillar is elastically connected to the installation member. The clamping member is opposite to the locating member to form a clamping part together with the locating member. The floating pillar is moveable between a first position, where the floating pillar shields the second locating pillar and a second position where the floating pillar exposes the second locating pillar. A sliding rail is further disclosed.

Abstract: A data storage device carrier includes a first supporting bracket and an upper cover. The first supporting bracket includes a first bottom plate and two first side plates, each of the first side plates defines an opening on an upper end and a sliding slot; the upper cover is slidably attached to the first supporting bracket, the first supporting bracket is configured to accommodate the first data storage device, the limiting columns are respectively received in the sliding slots via the openings, the top plate is configured to resist the upper surface of the first data storage device, the top plate comprises a connecting piece for connecting with another supporting bracket. A data storage system is further disclosed.

Abstract: A chassis in a device housing includes a housing of the housing, a hard disk drive, and a fastening apparatus. The housing includes a backplane and a side plate defining an opening. The hard disk drive defining an opening is electrically coupled to the backplane. The fastening apparatus includes a connecting member and a fastening member. The connecting member includes a connecting post. The connecting post defines a mounting hole. Two locking protrusions protrude from the connecting post. A raised portion protrudes from an inside wall of the mounting hole. The fastening member includes an urging portion. The fastening apparatus is coupled between the hard disk drive and the side plate. The fastening member is mounted in the mounting hole, and the raised portion is urged by the urging portions. The connecting post undergoes elastic deformation, and the locking protrusions are locked in the openings.

Abstract: A thermal dissipation system for a server includes a compressed air generating device, a compressed air transmission device, and a controller coupled to the compressed air generating device and the compressed air transmission device. The compressed air generating device includes at least one compressed air source for outputting compressed air. The compressed air transmission device is coupled to the compressed air generating device, and is configured to transmit the compressed air to a server, to make the temperature of air inside the server can be outputted with the compressed air. The controller is configured to detect the heat in the server through the compressed air transmission device, and control values of the pressure and airflow of the compressed air output from the compressed air generating device, according to the heat detected of the server. Therefore, the thermal dissipation system can output compressed air with higher pressure and greater airflow.

Abstract: A fault detecting system for a server includes a field programmable gate array (FPGA) unit and an user interface. The FPGA unit is configured to detect at least one fault signal of the server, and to output fault signal in form of logic level. The user interface includes a processing unit and a display. The processing unit is configured to receive the fault signal in form of logic level, and to determine whether the logic level of the fault signal is changed. In event the logic level of the fault signal is changed, the processing unit output a fault message to the display. Therefore, user can be prompted a position of the fault of server through the display.
