The invention discloses a method for adjusting the left and right volume of earphones. A first sensor is arranged on the ear-in portion of the main earphone, and a second sensor is arranged on the ear-in portion of the slave earphone; A vibration signal obtains the first volume heard by the user; the main earphone obtains the second volume of the slave earphone, and the second volume is obtained from the second vibration signal detected by the second sensor; the main earphone adjusts the volume according to the first volume and the second volume. At least one of the earphone volume of the terminal and the earphone volume of the slave earphone, so that the user's left and right ear volumes are balanced. The invention also discloses an earphone and a storage medium. The present invention adjusts the volume of the user's left and right ears according to the volume actually heard by the user. If the degree of fit between the main earphone and the left ear canal is different from that between the slave earphone and the right ear canal, the hearing imbalance between the left and right ears of the normal user can be automatically adjusted. The balance adjustment does not require the user to wear the headset again, which brings convenience to the user.

The invention discloses a power grid rush-repair ladder capable of being used on a slope. The power grid rush-repair ladder capable of being used on the slope comprises an electric control box for theladder, wherein a working cavity is formed in the electric control box for the ladder; a forking assembly is arranged in the working cavity; and the forking assembly comprises an annular slide groovewhich is fixedly formed in the inner wall of the right side of the working cavity and annular, and a first through hole formed in the inner wall of the right side of the working cavity and communicating with the outside.

The invention discloses a method for controlling the balance of vertical and horizontal imbalances of a secondary network. By setting the temperature sensor, the water supply temperature, return water temperature and indoor temperature are collected; the dynamic flow balance valve is set on the heating pipeline of each user; each unit is respectively equipped with a collection concentrator, which is used to collect the water supply temperature and return water temperature of each household and indoor temperature, the collection concentrator communicates with the remote control center. During regulation, according to the indoor target temperature and outdoor temperature, as well as the current indoor temperature, supply water temperature and return water temperature, the target value of the average temperature of the user's supply and return water is calculated and sent to the dynamic flow balance valve. The average temperature of the water level controls the increase and decrease of the flow rate until the stabilized indoor temperature reaches the indoor target temperature. The invention solves the problem that it is difficult to adjust the vertical and horizontal imbalances in the secondary network system at the same time, and the problem that the indoor temperature of each household is unbalanced leads to large measurement errors.
