Abstract: A method for standardizing an object model of an Internet of Things (IoT) terminal includes requesting an IoT terminal connected to the IoT management platform to upload respective object model data and if the IoT terminal supports uploading its own object model data, updating, according to the object model data uploaded by the IoT terminal, a first object model that matches the object model data. If the IoT terminal does not support uploading its own object model data, the method includes acquiring an object model log of the IoT terminal, and formatting log data in the object model log to obtain target log data. The method further includes sending the target log data to a big data platform to enable the big data platform to generate a second object model according to the target log data, and if the second object model is received, storing the second object model.

Abstract: A concrete interface agent relates to the technical field of concrete surface protection, an ingredient of the concrete interface agent comprises 55 to 100 parts by weight of a nano-calcium salt solution and a nano-SiO2 precursor, 0.1 to 0.4 parts by weight of a surfactant, 30 to 60 parts by weight of a silane coupling agent and 10 to 40 parts by weight of a polydimethylsilane, an ingredient of the nano-calcium salt solution comprises 2 to 5 parts by weight of a calcium hydroxide, 2 to 5 parts by weight of an acid catalyst and 200 to 500 parts by weight of an alcohol-based organic solvent, which can form a coating layer with higher hydrophobic angle on the concrete surface, reduce the water absorption of the concrete, and is not easy to crack after drying, which has more protective effect and longer service life than the existing TEOS interface agent.

Abstract: An energy dynamic control method for the EPS with hybrid power supply and an energy dynamic control system. Control system collects real-time current of vehicle electric appliances except the steering motor and the super-capacitor and calculates target current of the steering motor according to real-time steering torque and vehicle speed, and determines state of the super-capacitor by comparing rated current of vehicle power supply and sum of the current of vehicle electric appliances and target current of the steering motor. When super-capacitor is in the charging state, charging current is dynamically regulated to make vehicle power supply work in optimal working range, and maximum charging current is limited based on SOC of the super-capacitor. When super-capacitor is in discharging state, discharging current is dynamically regulated to make vehicle power supply work in optimal working range, and maximum discharging current is limited based on SOC of super-capacitor.
