The invention discloses a working method of a dynamic token. The working method comprises the following steps: judging the type of the pressed key when an effective key is detected by the dynamic token, detecting whether a current starting-up mark is set when the pressed key is a power key, restoring if yes, otherwise, setting the key and checking whether a lock mark is set, logging in a decoding code input interface if yes, otherwise, logging in an information interface; deleting the data of the bottom end of a block buffer cache when the pressed key is a deletion key; storing corresponding data to the block buffer cache when the pressed key is a number key, and the dynamic token is unarranged at the information interface; judging whether the pressed time of the pressed key is longer than a predetermined time when the dynamic token is arranged at the information interface, logging in a power-on password correcting interface if yes, storing the corresponding data to the block buffer cache if not; judging whether the data in the block buffer cache is true or qualified when the pressed key is the enter key and the dynamic token is unarranged at the information interface, generating a dynamic password and displaying corresponding content when the dynamic token is arranged at the information interface.

The invention discloses an electricity market subject market-oriented transaction behavior credit evaluation method. The electricity market subject market-oriented transaction behavior credit evaluation method comprises the steps: 1, establishing a credit rating index system; 2, collecting actual transaction historical data of an electricity market, and calculating and correcting each index weightby using a comprehensive weight method; and 3, based on the index weight, establishing an index scoring standard and a credit main scale. The electricity market subject market-oriented transaction behavior credit evaluation method solves the problems that in the prior art, the electricity market transaction credit rating evaluation range is small, and the quantification degree is low, and a market subject credit rating model with more market subjects and more comprehensive evaluation angles is not established, and the main credit of the electricity market cannot be accurately evaluated in real time and the like, can focus on key links of market-oriented transaction behaviors, and can satisfy the requirements for data collection, index quantification and evaluation.

The commodity pre-sales and after-sales management system comprises a commodity information entering terminal, an information processing terminal and a commodity money collecting terminal. The commodity information entering terminal, the information processing terminal and the commodity money collecting terminal are mutually networked. The commodity pre-sales and after-sales management system is characterized in that the commodity information entering terminal comprises a code reader A used for reading commodity information, an entering machine used for entering the commodity information, and an identification code printer used for printing an identification code; the information processing terminal comprises an information memory module and an information monitoring module; the commodity money collecting terminal comprises a cash register, a code reader B used for reading the commodity information and the identification code, and a bill printer used for printing a bill; the bill includes the information of the identification code. By the way of adding a novel identification code for a commodity, identification code information is recorded in the after-sales bill, thus, the unique corresponding relation of the after-sales commodity and the bill can be formed, and the malice claim for compensation of a consumer through the mode that a novel bill is matched with an expired commodity can be effectively prevented.

The invention relates to a simulating calculation based intelligent rotary mechanical fault diagnosis system and method. A data acquisition module acquires vibration data of an original analog quantity in the operation process of a unit, processes frequency-domain data to obtain characteristic parameters of vibration, and obtains thermodynamic data, including temperature, pressure and flow, of theunit; a simulating calculation module carries out simulating calculation, of a dynamic system, on the acquired vibration data and thermodynamic data; and a health monitoring and fault diagnosis module compares a real-time simulation calculation result with actual operation data of the unit to evaluate the operation state of the set, and feeds back the evaluated operation state to a human-computerinterface, so that operation staff can use the operation state as reference. Thus, the operation staff can pre-discriminate the mechanical vibration fault timely, and loss generated by vibration fault can be prevented.
