Description
Technical Field
The invention belongs to the field of stage and landscape lamps, and particularly relates to the field of a DMX lamp for wireless upgrading of a computer.
Background
Currently, professional stage and landscape lamps are increasingly widely used, and although DMX512 control protocols different from those of traditional lighting lamps are adopted, related wireless functions are still developed and applied.
In the existing lamp control system, if a lamp is to be subjected to system upgrade, two schemes exist:
1, copying an upgrade file into a lamp, then upgrading the lamp through the upgrade file of the lamp, and if the number of lamps needing to be upgraded is large, the operation is troublesome;
and 2, wirelessly transmitting and storing the upgrade file into a control box or a DFI controller, and starting upgrade setting through the control box or the DFI controller to upgrade the lamp. With respect to the first solution, it is possible to upgrade a plurality of luminaires simultaneously, but it does not actually implement a direct wireless upgrade from the handset to the luminaires, but rather an indirect setup and operation upgrade on the control box or DFI controller.
The patent document CN105208752B refers to a wireless control system and a control method for an LED lamp, in which the specific embodiment of the specification refers to "upgrading the lamp using WIFI", and the method includes the steps of:
a. compiling a lamp source code to generate a file in a BIN format by using Keil;
b. setting a DFI controller menu DFI Update- > Update Setting- > Else, and upgrading the lamp;
c. encrypting the compiled BIN format file through an UpladFirm application program;
d. WIFI of the DFI controller is connected by using UpladFirm;
e. sending the encrypted file to the DFI controller through WIFI;
the DFI controller temporarily stores the data sent by wireless into an external storage IC;
g. after the WIFI downloads all data, selecting a d-mode in a lamp menu, and long-pressing UP and DOWN keys for 1 second to enter an upgrading state (LOAD);
h. setting a DFI controller menu DFI Update- > YES;
and i, reading data in the external storage IC by the DFI controller, and sending the data to the lamp through the 2.4G wireless until the data is finished. "
As is known from e, f, g, h, the lamp is updated indirectly through the DFI controller by the second scheme described above.
In another example, patent document CN207075024U refers to an upgrade file transmission device and system, in which, in the specific implementation manners of the specification, examples one, two, three and four refer to "when the controller 11 receives an upgrade file, the upgrade file is not directly forwarded to the stage device 100, but is stored in the memory 13 first, and the upgrade file is transmitted to the stage device 100 after the upgrade file is stored successfully. It is seen that its upgrade mode is still indirectly upgraded by the controller.
As another solution for upgrading stage lighting equipment by using a mobile phone or a tablet computer in patent document CN103281828A, in the specific embodiment of the specification, the following steps are mentioned "a solution for upgrading stage lighting equipment by using a mobile phone or a tablet computer as shown in fig. 1: the stage lamp equipment establishes connection with special Wi-Fi equipment through a DMX communication interface (4); the special Wi-Fi equipment is connected with a mobile phone or a tablet computer which is provided with stage lamp equipment upgrade software and has Wi-Fi function through an antenna (5), and a password is set or not set during connection; the mobile phone or the tablet computer sends an upgrade instruction; the singlechip detects an upgrade signal and enters an upgrade mode; selecting software to be upgraded from a mobile phone or a tablet computer to send; the singlechip judges whether the software is compatible with the singlechip or not, if the software is incompatible, the software returns to reselect an upgrade file, if the software is incompatible, the upgrade is started, the normal starting state is automatically entered after the upgrade is completed, and the upgrade can be cut off.
The technical scheme disclosed in the above patent document adopts indirect upgrade through a controller, because the technical barrier for directly and wirelessly upgrading the DMX lamp by using a mobile phone or a computer is high, and the following conditions must be satisfied:
1-a mobile phone APP lamp program with complete architecture or a computer-controlled DMX lamp software can meet various control requirements of the DMX lamp and can be updated;

With reference to the foregoing embodiment one, it can be understood that when the computer wirelessly upgrades the DMX lamps X/Y/Z respectively, because each upgrade file includes identity information, when the identity information of the upgrade file is not matched with the identity information in the MCU of the DMX lamps, the DMX lamps do not take care that:
when the DMX lamp X lamp is upgraded, because the upgrade file contains the identity information of the DMX lamp X, the MCU b in the DMX lamp X compares the prestored model information of the DMX lamp X with the identity information in the upgrade file, the model information and the identity information are matched with OK, and the MCU b sends out an instruction to start automatic upgrade; meanwhile, the MCU c of the DMX lamp Y compares the prestored model information of the DMX lamp Y with the identity information in the upgrade file, the model information and the identity information are not matched, and the MCU c does not take care of the model information; similarly, the MCU d of the DMX lamp Z compares the prestored model information of the DMX lamp Z with the identity information in the upgrade file, the model information and the identity information are not matched, and the MCU c does not consider.

In this embodiment, the W-DMX wireless transmitting module and the W-DMX wireless receiving module are widely used in the current stage and landscape lighting industries, and the supplier is Wireless solution in sweden.
It can be understood by referring to the second embodiment that when the computer wirelessly upgrades the DMX lamps X/Y/Z, respectively, because each upgrade file includes identity information, when the identity information of the upgrade file is not matched with the identity information in the MCU of the DMX lamps, the DMX lamps do not take care of:
when the DMX lamp X lamp is upgraded, because the upgrade file contains the identity information of the DMX lamp X, the MCU b in the DMX lamp X compares the prestored model information of the DMX lamp X with the identity information in the upgrade file, the model information and the identity information are matched with OK, and the MCU b sends out an instruction to start automatic upgrade; meanwhile, the MCU c of the DMX lamp Y compares the prestored model information of the DMX lamp Y with the identity information in the upgrade file, the model information and the identity information are not matched, and the MCU c does not take care of the model information; similarly, the MCU d of the DMX lamp Z compares the prestored model information of the DMX lamp Z with the identity information in the upgrade file, the model information and the identity information are not matched, and the MCU c does not consider.
Similarly, when the DMX lamp Y lamp is upgraded, the DMX lamp X/Z does not give care to the upgrade file; when the DMX luminaire Z luminaire is upgraded, the DMX luminaire X/Y disregards the upgrade file.
As can be seen from the above-mentioned upgrading process, when 3 different types of lamps are simultaneously upgraded, no change needs to be made to the W-DMX wireless communication line and the lamps themselves, and the steps are the same as those of upgrading the 1 type lamps in the second embodiment, so that the simultaneous upgrading of multiple lamp types can be realized, and the only difference is the sequence.
The above embodiments are only for further description of the technical solution of the present invention, and not for limiting the protection scope of the present invention. It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
