The first embodiment is as follows:
fig. 1 shows a schematic flow chart of a data processing system provided in an embodiment of the present application, which is detailed as follows:
the data processing system includes: a device to be networked 101, a server 102 and a gateway 103.
And the device to be networked 101 is configured to send a visible light signal according to the communication key. The device to be networked 101 is specifically configured to: converting a binary system corresponding to a pre-stored communication key into coded data according to a first preset binary system conversion rule, wherein the binary system of the communication key is different from that of the coded data, for example, when the binary system of the communication key is hexadecimal, the binary system of the coded data can be binary; the visible light source is controlled to emit a visible light signal according to the encoded data, the encoded data includes a plurality of sub-parameters, the sub-parameters may be 0 or 1, for example, the encoded data 11110111 includes 8 sub-parameters, the 8 sub-parameters are 1, 0, 1, and 1, respectively, and the device to be networked 101 may support a ZigBee protocol.
Optionally, in the prior art, one sub-parameter only corresponds to one visible light intensity, so that the error probability of the communication key determined by the subsequent server is increased, and the network access efficiency of the device to be accessed to the network is reduced, which is illustrated in the following example: assuming that a corresponding system of a pre-stored communication key is hexadecimal, the communication key is FF, the communication key FF is converted into encoded data 11111111, and the encoded data 11111111 only has one sub-parameter "1", so that the encoded data only corresponds to one visible light intensity, and when a subsequent server determines the encoded data according to the visible light intensity, an abnormal condition that the sub-parameter bit number in the encoded data is wrong easily occurs, so that the communication key determined by the server is wrong, and further the network access failure of the device to be networked is caused. In order to improve the accuracy of data and the network access efficiency of the device to be networked, therefore, when the device to be networked 101 performs the control of the visible light source to emit the visible light signal according to the encoded data, the method specifically includes:
a1, determining the duration of the first visible light intensity and the duration of the second visible light intensity according to the sub-parameters in the coded data and the preset sub-parameter time length, wherein the duration of the first visible light intensity and the duration of the second visible light intensity meet the following conditions: the sum of the duration of the first visible light brightness and the duration of the second visible light brightness is equal to a preset sub-parameter time length, and it needs to be ensured that a quotient obtained by dividing the duration of the first visible light brightness by the duration of the second visible light brightness is equal to a preset quotient, different sub-parameters correspond to different preset quotients, and the preset sub-parameter time length is a time length in which the device to be networked 101 controls the visible light source to emit a visible light signal so as to display one sub-parameter.
And A2, controlling the visible light source to emit the visible light signal according to the duration of the first visible light intensity and the duration of the second visible light intensity.
For example, as shown in fig. 2, assuming that the time length of the preset sub-parameter corresponding to the sub-parameter 1 is 0.96 ms, and the preset quotient corresponding to the sub-parameter 1 is 3, it can be determined that the duration of the first visible light intensity and the duration of the second visible light intensity are 0.72 ms and 0.24 ms, respectively, so as to satisfy the following conditions: the sum of the duration of the first visible light intensity and the duration of the second visible light intensity is equal to a preset sub-parameter time length of 0.96 ms, and it is required to ensure that a quotient of the duration of the first visible light intensity divided by the duration of the second visible light intensity is equal to a preset quotient 3, and then controlling the visible light source to emit the visible light signal according to the duration of the first visible light intensity and the duration of the second visible light intensity is specifically: after the duration of the visible light signal with the first visible light intensity emitted by the visible light source is controlled to be 0.72 milliseconds, the duration of the visible light signal with the second visible light intensity emitted by the visible light source is controlled to be 0.24 milliseconds.
Because one sub-parameter corresponds to two kinds of visible light brightness, for example, 8 sub-parameters 1 are provided in the coded data 11111111, each sub-parameter 1 corresponds to two kinds of visible light brightness, and one coded data 11111111111 needs to be displayed by a visible light source, the visible light source needs to be controlled to jump between two kinds of visible light brightness for many times, so that the server can determine the number of bits of the sub-parameters in the coded data more easily and more accurately, and therefore, the accuracy of the coded data determined by the server and the network access efficiency of the device to be networked are greatly improved.
