[0024] Based on the power management method for smart electric boxes suitable for power management of projection equipment, the method includes: a network receiving module obtains a command from a theater TMS system; a logic control module retrieves the command from the memory according to the command Matching on/off configuration file; the strong current execution control module according to the on/off sequence of the strong current channels in the on/off configuration file, and the on/off delay interval of two adjacent strong current channels in the sequence , Execute the on/off of the strong current channel. Wherein, the command is any one of a show command, a power saving command, and a business suspension command.
[0025] More detailed explanation:
[0026] (1) The function description of each module
[0027] The logic control module is responsible for receiving the command sent by the cinema TMS system, and searching for a configuration file matching the command according to the command.
[0028] The network receiving module is responsible for realizing the connection between the logic control module and the cinema TMS system;
[0029] The storage module is responsible for storing multiple configuration files. The configuration files include: the opening/closing sequence of each screening-related device, the correspondence between each screening-related device and the channel number of the strong current channel, and the channel number of each strong current channel ;
[0030] The strong current execution control module is responsible for executing the power on/off operations of each strong current channel according to the configuration file.
[0031] The logic control module in the smart electric box in this embodiment searches for the configuration file, and the high-current execution control module performs power-on/off operations on the high-current channel physically connected to each device according to the configuration file, so the logic control module and the high-current execution control The module is the key for the smart electric box to realize automation and accurately control the sequence on and off of theater projection equipment. Therefore, the smart electric box in this embodiment has a function that can be configured according to business logic.
[0032] (2) Smart electric box and external equipment
[0033] The smart electric box is wirelessly or wiredly connected with the equipment related to the projection, and the equipment related to the projection includes: a projector, a playback server, an audio device, a field lamp and a curtain.
[0034] (3) Door opening protection function of smart electric box
[0035] The door opening of the smart electric box is provided with a protection lock, the protection lock is connected with a hardware detection circuit provided inside the smart electric box, and the hardware detection circuit is connected with the power up/down switch of each strong current channel.
[0036] For safety reasons, the smart electric box also adds a door opening protection function. The smart electric box door itself has a protective lock. In order to further ensure personal safety, the smart electric box can detect that the door is opened, and then it will prohibit the strong current channel. The principle of power-on and power-off operation is simply to use the hardware circuit to detect whether the box door is open, and then the software will not perform power-on and power-off operations on the power channel.
[0037] (4) Automatic projection function, automatic power saving function and automatic shutdown function
[0038] 1. Automatic screening function
[0039] When the command is a projection command, the on/off configuration file matching the projection command includes: the channel number of the strong current channel; the one-to-one correspondence between each of the projection-related equipment and the channel number of the strong current channel; each is related to the projection The sequence in which the equipment is turned on; the time interval between the opening times of two adjacent equipment related to the screening in the sequence.
[0040] The reason why the smart electric box described in this application can realize the automatic and accurate operation of the theater projection equipment is because after the network module of the smart electric box receives the projection command, the logic control module first checks the configuration file on the storage module. Find out which devices need to be turned on when executing the show command, the boot sequence of these devices, the time interval between the booting of two adjacent devices in the boot sequence, and the channel number of the strong current channel corresponding to each device , And finally through the strong current execution control module, the strong current channels involved in the show command are turned on sequentially and with time intervals.
[0041] 2. Automatic power saving function
[0042] When the command is a power saving command, the on/off configuration file matching the power saving command includes: the channel number of the strong current channel; the one-to-one correspondence between the projection equipment and the channel number of the corresponding strong current channel, and the playback server and The corresponding one-to-one correspondence of the channel number of the strong current channel; the opening sequence and the time interval of the opening time of the projection equipment and the playback server.
[0043] 3. Automatic shutdown function
[0044] When the command is a business shutdown command, the on/off configuration file matching the business shutdown command includes: the channel number of the strong current channel; the one-to-one correspondence between each of the projection-related equipment and the channel number of the strong current channel; each is related to the projection The sequence in which the equipment is closed; the time interval between the closing time of two adjacent equipment related to the screening in the sequence.
[0045] Similarly, the smart electric box will also receive, for example, shutdown commands, power saving commands, etc. The shutdown command is to shut down all the theater equipment, and the power saving command is to open only the projector and the playback server to facilitate film transmission tasks, and other devices to shut down . The implementation of these two commands is the same as the "show" command. It is also that the logic control module searches for the configuration file after receiving the command through the network signal receiver, and sequentially turns on and off the devices involved in the configuration file, while ensuring that the equipment and equipment are The power operation of the time has a delay interval.
[0046] (5) One-key on/off function
[0047] The smart electric box is also provided with a one-key on/off module, the one-key on/off module captures the artificial on/off operation on the smart electric box, and then forms an on/off command to turn the on/off The shutdown command is transmitted to the logic control module, and the logic control module uses the on/off command as the corresponding projection command or shutdown command, and retrieves the matching on/off configuration file from the memory according to the projection command or the shutdown command.
[0048] That is: the one-key shutdown module described in this embodiment realizes that when there is no need to receive the shutdown command sent by the theater TMS system, just press a shutdown button on the smart electric box, and you can quickly and automatically check each and show Relevant devices are turned on/off one by one and sequentially, using the logic control module to first look up the configuration file internally, and then the strong current execution control module performs up/down point operations on the involved strong current channel numbers according to the configuration file to achieve one key Shut down. The one-key switch function can usually be applied to scenes such as a theater network failure or other situations in the theater that need to switch the machine quickly.
[0049] (6) Software automatic update function
[0050] The smart electric box is also provided with a software management module, which is responsible for judging whether there is a new version of the software it manages from the messages periodically interacting with the network, and if it exists, it will be downloaded from the server to which the new version software belongs and automatically updated ; If it does not exist, continue to judge.
[0051] (7) Smart electric box has a wide range of applications
[0052] The smart electrical box described in this embodiment can control equipment with different content in different theaters. The software in the smart electrical box will match almost all types of projection equipment in the theater in advance, and then generate configuration files according to the on-site configuration during on-site installation. The electric box can automatically control the cinema equipment.
[0053] The main difference between the smart electric box described in this embodiment and the traditional power distribution box: the smart electric box described in this embodiment has the door opening protection function, automatic projection function, automatic power saving function and automatic shutdown function of the smart electric box, and one-key opening /Shutdown function, automatic software update function, and a wide range of applications, therefore, the smart electric box described in this embodiment ensures that the theater and projection-related equipment are safer, and can be accurately powered on and run, while reducing theater operating costs.
