The invention relates to the electronic payment and information safety field, and discloses interface conversion equipment communicating with a safety device used for calculating electronic payment codes and a method thereof. The invention is primarily used for interface conversion when the invention communicates with the safety device to calculate the electronic payment codes. The invention can effectively ensure that a PC computer or bank computer terminal equipment connects with and communicates with the safety device in USB-key mode to calculate the electronic payment codes; mains input can be provided for the safety device to calculate the electronic payment codes during communication. At the same time, the equipment can also independently support the connection with prior hand-held electronic payment coder equipment through standard serial port transfer lines, and is compatible with such operations and functions as initialization and loading account information of prior hand-held electronic payment coder equipment at the bank terminal.

The application provides an automatic teleprompter method for video recording. The method comprises the following steps: inputting designed script into a teleprompter system, placing a sentence to berecorded in the script in the center of a teleprompter center to display; collecting voice information of video-recorded personnel, identifying the voice information of the video-recorded personnel, and converting the voice information into text information; matching the text information with the sentence at the center of the teleprompter screen; if the matching is successful, moving the next sentence in the script to the screen center of the teleprompter by the system; if the matching is unsuccessful, further judging whether the matching dissimilarity t is greater than the preset threshold T,if the matching dissimilarity t is greater than the preset threshold T, automatically interrupting and ending the prompting; if the matching dissimilarity t is not greater than the preset threshold T, giving caution information in different levels according to the size of t, and enabling the video recorder to decide whether to end; if the video recorder decides not to end, continuously performingvoice information collection, identification and subsequent flows, or directly ending the operation.

The invention relates to analog switch circuit and a secondary current detection circuit for an inversion resistance welding machine. The analog switch circuit comprises a comparison circuit, a detection circuit, and an electronic switch circuit. The input end of the comparison circuit is connected with a Rogowski coil voltage signal output end, and the output end of the comparison circuit is connected with the input end of the detection circuit. The output end of the detection circuit is connected with the control end of the electronic switch circuit. The comparison circuit compares a Rogowski coil output voltage signal with a preset comparison voltage, and outputs a control signal to the detection circuit. The detection circuit transmits the control signal to the control end of the electronic switch circuit after detection processing of the control signal, and the electronic switch circuit controls a fixed integrating circuit and an adjustable integrating circuit to switch the working states according to the processed control signal, wherein the fixed integrating circuit and the adjustable integrating circuit are connected with the electronic switch circuit. The analog switch circuit can control the integrating circuits to switch the state between an integrating state and a non-integrating state, effectively reduces the time of an integrating capacitor in the integrating circuits in arriving at a saturation state, and guarantees the stability of a system.
