This disclosure discloses a method, apparatus, and system for controlling multiple air conditioning devices, as well as air conditioning equipment and a storage medium. The method includes: determining whether the multiple air conditioning system is in a state without central control; when the system is in this state, acquiring the average ambient temperature and a set temperature; determining the number of air conditioning devices to be turned on based on the average ambient temperature and the set temperature; and determining whether the current air conditioning device needs to operate based on the number of devices turned on and the operating time of all air conditioning devices in the system. The multiple air conditioning system includes a central control device and multiple air conditioning devices, and the control method is executed by a control device located on the current air conditioning device. In the state where the multiple air conditioning system is in a state without central control, the air conditioning devices within the system can automatically control their on / off states and maintain the ambient temperature.

This invention provides a single-sided tin-coating device for triangular conductive wires, including a tin-spraying mechanism and a protective wheel assembly. The tin-spraying mechanism includes a tin pot, a molten tin pumping device, a nozzle, and a flow control valve. The protective wheel assembly includes two consecutively arranged V-grooved wheels. Two sides of the triangular conductive wire are inserted into the V-grooves of the V-grooves, exposing the tin-coating surface. The nozzle of the tin-spraying mechanism is located between the two consecutively arranged V-grooved wheels, facing the exposed tin-coating surface of the triangular conductive wire. Using this single-sided tin-coating device for triangular conductive wires, the thickness of the tin layer can be controlled, production efficiency and yield can be improved, and long-distance, non-overflowing, non-broken, and uniformly controllable tin layer thickness of the single-sided tin-coated triangular conductive wires can be produced, thereby greatly improving production efficiency.
