Abstract

An equipment unit state controlling method and device, and an equipment unit. After receiving control data transmitted from a state controller, a unit controller detects whether the unit controller communicates with a display panel controller, in which the state controller transmits the control data to the unit controller and the display panel controller simultaneously. If the unit controller communicates with the display panel controller, the unit controller performs an operation on the equipment unit corresponding to instruction information transmitted from the display panel controller, and if the unit controller does not communicate with the display panel controller, the unit controller parses the control data by itself to obtain the parsing result and performs the operation on the equipment unit corresponding to the parsing result.

Claims10

Dependent claims

A method for controlling a state of an equipment unit performed by an unit controller, comprising:

detecting whether the unit controller communicates with a display panel controller after receiving control data transmitted from a state controller, wherein the control data are also transmitted from the state controller to the display panel controller;
performing an operation corresponding to instruction information transmitted from the display panel controller on the equipment unit in a case where the unit controller communicates with the display panel controller, wherein the instruction information corresponds to a first parsing result obtained by the display panel controller parsing the control data;
and
parsing the control data to obtain a second parsing result in a case where the unit controller does not communicate with a display panel controller, and performing an operation corresponding to the second parsing result on the equipment unit, wherein the performing the operation corresponding to the second parsing result comprises:
extracting delay information from the second parsing result in a case where the control data are unit encryption instruction information;
performing a delay process corresponding to the delay information, wherein the performing a delay process comprises:
transmitting a current remaining delay information to the display panel controller for the display panel controller to use the remaining delay information to continue the delay process in a case where a communication between the unit controller and the display panel controller is recovered during the delay process;
and
locking the equipment unit after receiving a locking instruction transmitted from the display panel controller, wherein the locking instruction is transmitted after the display panel controller finishes the delay process;
and
locking the equipment unit after the delay process.

8 more elements

A unit controller for controlling the state of an equipment unit, comprising:

a non-transitory memory configured to store instructions;
a processor coupled to the memory and configured to:
detect whether the unit controller communicates with a display panel controller after receiving control data transmitted from a state controller, wherein the control data are also transmitted from the state controller to the display panel controller;
perform an operation corresponding to instruction information transmitted from the display panel controller on the equipment unit in a case where the unit controller communicates with the display panel controller, wherein the instruction information corresponds to a first parsing result obtained by the display panel controller parsing the control data;
and
parse the control data to obtain a second parsing result in a case where the unit controller does not communicate with a display panel controller, and perform an operation corresponding to the second parsing result on the equipment unit, wherein the perform the operation corresponding to the second parsing result comprises:
extract delay information from the second parsing result in a case where the control data are unit encryption instruction information;
perform a delay process corresponding to the delay information, wherein the performing a delay process comprises:
transmit a current remaining delay information to the display panel controller for the display panel controller to use the remaining delay information to continue the delay process in a case where a communication between the unit controller and the display panel controller is recovered during the delay process;
and
lock the equipment unit after receiving a locking instruction transmitted from the display panel controller, wherein the locking instruction is transmitted after the display panel controller finishes the delay process;
and
lock the equipment unit after the delay process.
