The application discloses a kind of based on blockchain transaction processing method, controller, storage medium and equipment, belong to blockchain technical field.The method includes: transaction pool module stores transaction in the form of key-value pair to transaction area, value includes transaction label and transaction data, transaction label is set to first content, indicates that transaction is not confirmed;Select a plurality of transactions that are not confirmed to form candidate block;Chain module synchronizes candidate block to proposal area, and synchronizes one confirmation block selected from the candidate block of proposal area to confirmation;Transaction pool module sets the transaction label of transaction in confirmation block to second content, indicates that transaction has been confirmed, deletes the candidate block of proposal area except confirmation block;Data in transaction area, proposal area and confirmation are synchronized by synchronization module based on CRDT.This application can decouple the coupling between synchronization module and verification module, transaction pool module and chain module, reduce the design complexity of synchronization module.

The invention discloses a plug-in loading method for Excel format update, which is characterized by comprising the following steps of: S100, starting a host main program, finishing initialization of a main program core service and starting a plug-in loader for loading a plug-in when the host main program has the capability of responding to an external component; s200, the plug-in loader obtains configuration information of the configuration file; s300, judging whether configuration information of the configuration file is obtained or not, if yes, executing the step S400, and if not, executing the step S200; s400, the plug-in loader creates a plug-in monitor for communication between the main program and the plug-in and monitoring a life cycle event of the plug-in; s500, a plug-in loader loads all plug-ins one by one from a directory according to the plug-in configuration information; s600, judging whether all plug-ins are registered and have no abnormity, if so, executing the step S700, and otherwise, executing the step S600; and S700, the plug-in loader reads the data template of the plug-in package, stores the content of the data template to the memory and binds the content to the current plug-in, and plug-in starting is completed.

The invention discloses a BMS high-voltage sampling circuit which comprises a high-voltage side sampling port, a voltage dividing module and an isolation operational amplifier module, the high-voltage side sampling port inputs a first voltage to the voltage dividing module, the voltage dividing module is used for dividing the collected first voltage to output a second voltage, the voltage dividing module inputs the second voltage to the isolation operational amplifier module, and the isolation operational amplifier module is used for outputting the second voltage. The isolation operational amplifier module is used for inputting the third voltage to the bias operational amplifier module, the bias operational amplifier module is used for enabling the third voltage to generate bias gain so as to output a fourth voltage, and the low-voltage side sampling port is used for receiving the fourth voltage. The bias operational amplifier module inputs a fourth voltage to a low-voltage side sampling port, and the low-voltage side sampling port is used for collecting the fourth voltage as a sampling voltage; during high-voltage sampling, isolation communication between high voltage and low voltage is not needed, an isolation power supply module does not need to be arranged, a sampling chip does not need to be arranged on the high-voltage side, the circuit is simple and high in reliability, and the sampling circuit can collect negative voltage.
