Abstract: A charging method and system, an electronic device, and a computer storage medium are disclosed. The system includes a first device and a second device. The first device includes a boost chip and a first battery. The second device includes a charge pump chip and a second battery. The first battery is configured to output a first voltage to the boost chip. The boost chip is configured to: receive the first voltage and output a second voltage to the second device, where the second voltage is greater than the first voltage. The charge pump chip is configured to: receive the second voltage and output a third voltage to the second battery, where the second voltage is M times the third voltage, and M is a positive number greater than 1. The second battery is configured to: receive the third voltage and perform charging.

Abstract: Provided are a dual injection system and a synchronization control method thereof. The system includes a primary injection system and a secondary injection system, where the primary injection system and the secondary injection system each include a speed injection oil circuit and a booster oil circuit; the speed injection oil circuit of the primary injection system and the speed injection oil circuit of the secondary injection system are arranged independently of each other; and the booster oil circuit of the primary injection system and the booster oil circuit of the secondary injection system each include an A-bridge valve group and are arranged in coordination with each other. The method is configured to perform a synchronization control on the primary injection system and the secondary injection system of the system.

Abstract: The invention discloses a method for implementing signaling link redundancy in IP networks. Two ASPs are created for the same AS in the host at the IP network side, and all user adaptation protocols share ASPSM and ASPTM messages so that the states of the two ASPs can become active and inactive respectively, thus to implement two signaling links for serving the same traffic. When switch is initiated, SCTP association can be closed by using “graceful close”, and the SCTP itself will make sure to send out all the data remaining in its buffer and its higher-layer applications will also send subsequent data in order after learning the remaining data are all sent out, thus sequential delivery for the data can be guaranteed. This method can avoid data loss and disorder, and the speed for switch can be ensured because the backup link will be notified immediately after the data on the primary link are sent out.
