2results about How to "Simplify overhead" patented technology

This application provides a payment processing method, apparatus, electronic device, storage medium, and program product. The method includes: receiving a payment transaction request from an acquiring node, the payment transaction request being triggered by a contactless payment operation of the acquiring node based on a payment terminal; processing the payment based on the payment transaction request, and determining whether the payment terminal meets the object distribution conditions of the target merchant based on the payment transaction request; when the object distribution conditions are met, sending a payment transaction response to the payment terminal, the payment transaction response including payment completion notification information and the target object of the target merchant, so that the payment terminal displays the payment completion notification information and the target object of the target merchant on the user interface. The payment result and target object distribution are completed in a single response, reducing the downlink message volume and thus significantly reducing the peak QPS pressure on the central gateway; secondly, target description information can be obtained without a secondary request, simplifying system interaction logic and network overhead.

A single-input double-output thyristor triggering method and device based on digital control, which obtains electric energy from an alternating current power supply; converts the collected anode-cathode voltage into a square wave signal synchronized with the alternating current power supply, and outputs the square wave signal to the input end of a digital control chip; determines the half cycle in which the current alternating current power supply voltage is located, and selects the first thyristor or the second thyristor to be turned on; outputs an adjustable-width trigger pulse to the gate of the thyristor corresponding to the trigger module through the trigger module, and controls the thyristor to be turned on. The advantages of the present application are: the trigger pulse width and the feedback pulse width are configured, all pulse width parameters are generated by software configuration of the digital control chip, and do not depend on any analog timing elements such as resistors and capacitors, thereby avoiding the problem of pulse width change caused by capacitor value temperature drift and long-term use value attenuation, ensuring the long-term stability of the trigger pulse and the feedback pulse width, and eliminating the risk of state misjudgment of the upper circuit caused by pulse width change.
