The invention discloses a connecting device for an escalator and a control method, the connecting device comprises double physical safety links, and two completely independent and electrically isolated physical safety links, namely a link A and a link B, are laid in parallel on the whole line of the escalator; the distributed safety node comprises a safety relay unit which comprises two pairs of normally open contacts KA and KB which are forced to guide and are completely synchronous in state, and the two pairs of normally open contacts KA and KB are respectively connected in a physical safety link A and a physical safety link B in series; the physical link on-off detection circuit is used for directly detecting voltage / current of a link A and a link B and judging the on-state of the link A and the link B, and the diagnosis excitation and measurement circuit comprises a precise constant current source and a high-precision voltage sampling and demodulation circuit and can be switched to a diagnosis bus. A test signal is injected into a diagnosis loop formed by a plurality of node coils, and a response is measured, so that a tough and adaptive safety protection system is constructed, and potential network attacks and internal faults can be resisted.

This utility model discloses a forklift bracket assembly with a front-end locking mechanism, comprising: a mounting plate, one side of which is fixedly connected to a connecting block, and the other side of which is fixedly connected to a surrounding frame; an unlocking assembly, one side of which is fixedly connected to one side of the mounting plate, and the unlocking assembly is used for directly unlocking the front-end locking mechanism; and a locking assembly, one side of which is fixedly connected to one side of the unlocking assembly, and the locking assembly is used for stably clamping the material to be clamped. This utility model relates to the field of bracket assembly technology. In this forklift bracket assembly with a front-end locking mechanism, the unlocking assembly is electrically driven to achieve the unlocking operation. An unlocking motor drives the screw sleeve and synchronous shaft to rotate, and works in conjunction with a limiting plate and a protruding plate to achieve precise positioning, enabling rapid switching of the locking state. This design avoids manual unlocking and allows for remote or automatic control.

The invention discloses a heating display board used for being installed on a fire grandstand, and belongs to the technical field of outdoor public facilities. The display board comprises a box body, a display screen, a heating mechanism, a fixing clamp and a controller. The interior of the box body is divided into front and rear independent containing spaces through a vertical partition plate, and the front and rear containing spaces are used for containing electronic elements on the back side of the display screen and the heating mechanism respectively so as to block direct heat transfer. The heating mechanism comprises an electric heating wire, a base plate, an outer shell and a heat dissipation wing plate and is used for radiating heat towards the stand. The controller integrates wireless communication and temperature sensing functions, and can control display content and heating power in a centralized manner. The problems of thermal interference and space occupation during display and heating function integration in an open-air viewing scene are solved, and miniaturization, safe and reliable operation and intelligent management of equipment are realized.
