The invention discloses a system and method for updating firmware through a heterogeneous network. A technical means lies in that after an update command is received through a target device, connection with a first wireless communication network is switched into connection with a second wireless communication network, an update file is received through the second wireless communication network, after the update of the firmware is completed by the update file, the connection with the second wireless communication network is switched into connection with the first wireless communication network, so that the situation that a bandwidth used by other normally-operated devices is influenced when new firmware is downloaded can be avoided, and the technical effect of simultaneously updating the firmware of a plurality of target devices is realized.

The invention discloses a yawing testing mechanism for a blower, which comprises a cabin bracket, a tower drum tool, an upper pivoting support, and a lower pivoting support; the lower end part of the cabin bracket is fixed on a yawing base, and the cabin of the blower is fixed at the upper end part; the tower drum tool is connected with a tower drum tool driving device through a transmission mechanism, and rotates around the axis of the tower drum tool under the action of the tower drum tool driving device; the upper pivoting support is mounted at the lower part of an underframe of the cabin,and is used for leading the tower drum tool to move relative to the cabin; and the lower pivoting support is mounted on the yawing base, and is used for allowing the tower drum tool to move relative to the yawing base. When the blower is in yawing test, the tower drum tool rotates while the cabin stands still; on one hand, as the yawing test can be conducted alongside the towing test on the blower, the testing time is saved, the testing efficiency is improved, and the testing operation is facilitated; and on the other hand, as the yawing test is carried out without the deflection of the cabin, the space for test is saved, and the installation is facilitated. On the basis of the mechanism, the invention further discloses a complete machine test stand for the blower.

Provided is a system for providing an update file via a heterogeneous network and a method thereof. The technical means is listed as follows: a target device is detected via a first wireless communication network, and the update file is transmitted via a second wireless communication network so that the target device connected with the first wireless communication network is enabled to use the second wireless communication network to receive the update file and update target data according to the update file, influence of downloading of the new target data on bandwidth used by other normally operated devices can be avoided, and the technical effect that the target data of multiple target devices are updated simultaneously can be achieved.

The invention relates to an intelligent starting system and method of fire-fighting equipment. According to the intelligent starting system and method of the fire-fighting equipment, when one smoke detector detects that the corresponding indoor space generates smoke, a warning signal is generated, furthermore, the warning signal and the detector information are sent to a management center, and themanagement center makes inquiry and finds the fire-fighting equipment and the fire-fighting equipment information at the same floor as the detector information; and then the equipment distance from the smoke detector to the corresponding fire-fighting equipment is calculated according to the detector information and the fire-fighting equipment correspondingly, so that when the equipment distancefrom the corresponding fire-fighting equipment to the smoke detector is smaller than a preset distance, a starting command corresponding to the fire-fighting equipment is generated, and the managementcenter transmits the starting command to the corresponding fire-fighting equipment so as to start the fire-fighting equipment so that the technical effect of providing intelligent fire-fighting equipment starting can be achieved.

The invention discloses a system and a method for carrying out pressure testing on a communication port through a core program; the technical scheme is that a testing program is established on a processor according to a sending parameter after the sending parameter corresponding to a connection port is set, and the processor is enabled to transmit and receive a test packet on the connection port through a drive program executed in a core program using network card in a computer according to the sending parameter; thus, an enough and large amount of data flow can be generated to carry out pressure testing on the network card; and the technical effect of directly testing the network device with different network cards mounted can be achieved.

The submersible pump stage comprises an impeller comprising a front cover disk and a rear cover disk, blades arranged between the front and rear cover disks, a sleeve and a guide apparatus, which comprises a front cover disk and a rear cover disk and blades arranged between the front and rear cover disks. The rear cover disk of the guide apparatus is equipped with through-openings which extend in end surfaces and are arranged circumferentially. The number of through-openings is selected to be at least equal to the number of interblade channels. The openings are formed in such a way that liquid can flow from a front pocket of this submersible pump stage into each interblade channel of the guide apparatus of the previous stage. The use of the claimed device reduces the abrasive wear on the cover disk of the impeller and significantly extends the service life of the electric motor.
