The utility model provides a pan-tilt driving motor starting capacitor board. The pan-tilt driving motor starting capacitor board comprises a switch interface module, an arc extinguishing module, a starting capacitor module and a network and power supply transmission interface module which are integrally configured on a circuit board, the arc extinguishing module is respectively connected with a motor limit switch of a holder driving motor, the camera device and the starting capacitor module through the switch interface module, and the network and power supply transmission interface module is configured to supply power to the camera device by external voltage and input network signals; in response to an electric energy signal sent to the pan-tilt driving motor by the camera device, the pan-tilt driving motor is controlled to act through the arc extinguishing module and the starting capacitor module; and in response to the moment that the contact of the trigger generator limit switch is disconnected, the arc extinguishing module absorbs transient voltage generated at the moment that the contact is disconnected so as to control the pan-tilt driving motor to stop acting. According to the application, the electric arc and sparking conditions generated by the position of the contact point in the limit switch during action in an alternating current power supply environment can be effectively inhibited, the contact point is effectively protected, the reliability is improved, the problem of control failure of the pan-tilt is avoided, and long-term stable operation of the pan-tilt is ensured.

The application relates to the technical field of suspensions, and discloses a double wishbone suspension for a vehicle and the vehicle, wherein the double wishbone suspension comprises a steering knuckle, an upper swing arm, a lower swing arm and a shock absorber; the steering knuckle is used for being connected with a vehicle wheel; one end of the upper swing arm is rotationally connected with the steering knuckle, and the other end is rotationally connected with a vehicle frame; one end of the lower swing arm is rotationally connected with the steering knuckle, and the other end is rotationally connected with the vehicle frame; along the height direction of the vehicle, the lower swing arm is arranged below the upper swing arm; one end of the shock absorber is rotationally connected with the upper swing arm, and the other end is connected with a vehicle body tower package. The universal design of the interface of the vehicle body tower package is realized; the space conflict problem caused by the fact that the shock absorber of the traditional double wishbone suspension cannot share the tower package with the shock absorber of a McPherson suspension is effectively avoided, and the vehicle body platformization and compatibility are realized.

The application discloses a kind of data high-precision acquisition processing systems of battery module, belong to acquisition processing system technical field, comprising: distributed intelligent acquisition module, digital communication connection line, main control and collaborative computing module and fast self-checking and protection circuit, the distributed intelligent acquisition module is used to connect and acquire the analog signal of each electric core or electric core module electric parameter and environmental parameter, and it is converted into original digital data, then original data is carried out online adaptive weighted data fusion, sparse sampling compression and feature extraction, generates situation data package, and according to time series prediction model dynamic adjustment data acquisition cycle to optimize energy consumption, simultaneously according to network state and data priority dynamic selection communication protocol and transmission path.The application can also be distributed intelligent acquisition on the basis of realizing high-precision acquisition processing to battery module, and can realize the intelligent closed loop of sensory transmission calculation protection depth cooperation.

The application provides a universal lost foam coating for cast steel and cast iron and a preparation method and application thereof, and relates to the technical field of lost foam casting. Raw materials of the lost foam coating include quartz powder, kaolin and iron liquid nodularizing slag micro powder, the iron liquid nodularizing slag micro powder is obtained by calcining treatment of iron liquid nodularizing slag, and the iron liquid nodularizing slag is obtained by nodularizing and slagging treatment of iron liquid in a nodular cast iron process; the mass percentage of the iron liquid nodularizing slag micro powder in the raw materials is 4-17%, the mass ratio of the quartz powder to the iron liquid nodularizing slag micro powder is 4-16:1, and the mass ratio of the kaolin to the iron liquid nodularizing slag micro powder is 0.6-3:1. The lost foam coating has suitable air permeability, high crack resistance and bending strength in a wide temperature range, can be simultaneously applied to cast iron and cast steel, realizes universal design of the coating, and reduces production cost while improving resource recycling rate.
