The application discloses a kind of softener automatic filling circulation systems and methods of gluing quantifying machine, the system includes: main controller, intermediate controller, power supply unit, gluing subsystem and lubricating subsystem, gluing subsystem includes the gluing controller for controlling gluing work, lubricating subsystem includes lubricating oil pump and relay, relay includes control coil and main contact, one end of control coil is connected with the output end of intermediate controller, the other end of control coil is electrically connected with the common end of intermediate controller;Intermediate controller is used to receive the gluing state signal sent by gluing controller and the operating state signal of lubricating oil pump, main controller is used to judge whether gluing subsystem satisfies lubricating condition according to gluing state signal and / or operating state signal, if yes, then send lubricating start signal to intermediate controller, intermediate controller is also used to control main contact to be connected according to lubricating start signal.

The invention discloses a charging and discharging control method for an elevator energy storage device and a related device, and relates to the technical field of elevator energy-saving control, and the method comprises the steps: constructing an action sequence optimization model comprising an action sequence, a target function and a constraint condition according to an electricity price prediction sequence and an elevator power prediction sequence in a prediction period, the target function represents the total net income of the system after actions in the action sequence are sequentially executed on the elevator energy storage device in the prediction period, and the total net income is jointly determined by the electricity charge income, the aging cost of the energy storage device and the abrasion cost of a control assembly of the energy storage device; the aging of the energy storage device and the wear of the control assembly of the energy storage device are quantified into cost, and the cost and the electric charge income are uniformly optimized, so that frequent operation of the control assembly of the energy storage device for pursuing small electric charge income or charge and discharge behaviors damaging the health of the energy storage device can be effectively avoided.

This utility model discloses a power-on / off testing circuit and device for electricity meters. The circuit includes a main control module, a 485 communication module, a power supply module, and a relay module. The 485 communication module is connected to a host computer and the main control module, and is used to receive power-on / off test parameters sent by the host computer, convert the test parameters into electrical signals, and input them to the main control module. The power supply module is connected to both the main control module and the electricity meter under test, and is used to provide power to both the electricity meter and the main control module. The relay module is connected to both the main control module and the electricity meter under test, and is used to control the electricity meter under test to perform power-on / off testing according to the electrical signals received by the main control module. This utility model can improve the testing effect and efficiency of power-on / off testing of electricity meters.
