On-line monitoring methods for high-voltage circuit-breaker switching on-off time

The present invention relates to a method of monitoring the gate opening and closing time on line by a high-voltage circuit breaker. The inception time for the breaker gate opening and closing coil with electricity can be obtained through the voltage telecommand sampling of the breaker gate opening and closing coil, the time for the separation and connection of breaker head can be obtained through three-phase voltage telecommand sampling of capacitance sensor of high-voltage electricity-carrying display device that is arranged on the electric power transmission lines. The time gap between the inception time of breaker gat closing coil with electricity and the finish time of separation of breaker head is calculated, then the gate opening time is worked out; the time gap between the inception time of breaker gate closing coil with electricity and the finish time of jointing of breaker head is calculated, then the gate closing time is worked out. The method of the present invention bases on the telecommand sampling of voltage signal; brings the operating facilities of electric power system into full play; and overcomes the shortcomings of previous online monitoring methods; thereby making the verification of time point more conveniently and accurately, and reducing the cost, thus being favorable for the realization of state repairing of the breaker.

Method for preventing cool roller bed of hot rolling layer from steel rear-end collision

The invention relates to a method for preventing a cool roller bed of a hot rolling layer from steel rear-end collision. The rolling rhythm of adjacent front band steel and back band steel are controlled according to different steel types and specifications based on a preset technique requirement through a hot metal detector combined with a basic automatic controller and a process controller; and under the premise of ensuring the rolling rhythm, steel rear-end collision of a layer cool zone due to differences in steel types and specifications can be avoided. The method includes the steps: 1, theoretically calculating out a time gap value T between the tail of the front band steel and the head of the back band steel; 2, practically detecting and calculating out a real time gap value T ' between the tail of the front band steel and the head of the back band steel; and 3, comparing the T and the T ', and issuing an on-site swinging command or a moving command to the back band steel according the comparison result. The method can shorten overlong gap time during manual control processes, reduce unnecessary time waste, and can avoid steel rear-end collision of the layer cool zone due to differences in steel types and specifications under the premise of ensuring the fastest rolling rhythm.

Multi-source data grid fault identification method

The invention provides a multi-source data grid fault identification method, and relates to the field of dispatching automation of electric power systems. When an electric system is dispatched, the advantage that diagnosis is conducted by only depending on protecting action information is not beneficial for the judgment and immediate processing of an accident. The multi-source data grid fault identification method includes the following steps of setting up a parameter, collecting grid operation information in real time, sorting out grid fault reports when receiving action information of a relay protection device, organizing action reports according to a protection device when a real fault signal is detected, taking the time scale of the earliest received protection action as the zero-time of the action report, if other protection action signals belong to the same device and the time gap between the action time and the zero-time is less than a threshold value, arranging the protection action signals to be in the same action report, if received scattered wave records belong to the same device and the time gap is less than the threshold value, arranging the received scattered wave records to be in the same report. According to the technical scheme, after a fault occurs in the electrical system, the real grid fault can be quickly and accurately identified, and a clear grid fault report can be organized.

Method for renting idle private car parking stall

The invention discloses a method for renting an idle private car parking stall, comprising a third-party platform, a private car parking stall rent-seeker and a private car parking stall leaser. The private car parking stall rent-seeker and the private car parking stall leaser fill relevant information in a downloaded third-party APP. Then, the third-party APP collects all the parking stall rental information for the parking stall rent-seeker to screen the parking stall that meets his or her requirement; and then, with a deposit, the parking stall can be booked and used. When the parking stall rent-seeker leaves the parking stall, the rental fee is deducted and the remaining deposit is returned. At the same time, the rent seeker also receives a rental-fee deduction message as evidence so that he or she does not pay parking fee to a community property management company. The third-party platform also receives the booking from other qualified parking stall leasers through the use of the time gap between the parking stall rent-seeker and the parking stall leaser. According to the invention, through the management of the idle parking stalls, a driver no longer worries about trying to find a parking stall. In addition, the utilization efficiency of the fixed parking stalls is also raised; and pressure on a current parking lot is also eased.

Method for rapidly decomposing time gap conflicts in distributed type TDMA protocol

The invention discloses a method for rapidly decomposing time gap conflicts in a distributed type TDMA protocol. The method mainly solves the problem that in an Ad Hoc network, due to the time gap conflicts, the transmission efficiency and channel utilization rate are decreased. The method includes the steps that firstly, a node has access to a network and is marked with a time gap type; secondly, when receiving a correct packet during a receiving time gap, the node calculates prediction parameters according to the physical layer parameters of the packet and conducts conflict forecasting decomposition if the prediction parameters meet the conflict prediction conditions; thirdly, when receiving a wrong packet during the receiving time gap, the node conducts conflict decomposition if physical layer parameters of the packet meet the conflict conditions; fourthly, when receiving no packet during the receiving time gap or receiving a correct packet during an idle time gap, the node renews a time gap list. The cross-layer design is introduced, and therefore the time gap conflicts are more efficiently predicted and detected, the network transmission efficiency and channel utilization rate are increased, and the method can be used for the distributed type self-organized network.
