Fig. 1 shows a circuit schematic diagram of a carrier communication circuit 100 provided in a first aspect of an embodiment of the present application, and for convenience of description, only parts related to the embodiment are shown, and detailed as follows:
the carrier communication circuit 100 in the present embodiment includes: the main control circuit 110 and the power data transmission circuit 120 are connected, and the power data transmission circuit 120 is electrically connected with the external powered device 10 through power lines (PIN +, PIN-, wherein the power line PIN + is a positive power line and the power line PIN-is a negative power line). The main control circuit 110 is configured to output a control signal Vtrl1 with a preset magnification according to the first data signal; the power data pass-along circuit 120 is configured to supply power to the external powered device 10 via the power line (PIN +, PIN-) and to output a first electrical signal Singal1 representing the first data signal to the external powered device 10 via the power line (PIN +, PIN-) under the control of the control signal Vtrl 1.
It is understood that the master control circuit 110 may be formed by a microprocessor, such as a single chip or other master control chip. The power data synchronous circuit 120 may be formed of an electronic switch or the like, and is turned on or off by the control signal Vtrl1 to generate and output the first electrical signal single 1 to the external powered device 10.
It is understood that the first data signal is communication data of the master control circuit 110 communicating with the external powered device 10, and the first data signal may be a digital signal. The first electrical signal Singal1 is a level signal string composed of a plurality of level signals. The control signal Vtrl1 may be a level signal with a preset multiplying factor of high and low levels of a preset proportion, or may be a duty cycle within any time length.
It is understood that the carrier communication circuit 100 in this embodiment may be disposed in a device including a power supply or a power interface, such as a cabinet for supplying power to a power bank. The external powered device 10 is a device that needs external power to operate or store energy, and the external powered device 10 may also supply power to other devices, such as a power bank.
In this embodiment, by using the main control circuit 110, the control signal Vtrl1 with a preset magnification is output according to the first data signal, and by using the power data transmission circuit 120, the first electrical signal single 1 representing the first data signal is output to the external powered device 10 through the power line while the external powered device 10 is powered through the power line, that is, the device using the carrier communication circuit 100 can realize power supply and communication with the external powered device 10 through the power line. Further, the cabinet provided with the carrier communication circuit 100 is not connected with the external powered device 10 (charger baby), so that the defective communication rate is reduced, and the problems that the number of communication interfaces is limited, the communication is poor and the order cannot be ended easily in the conventional cabinet-charger baby communication circuit are solved.
In one embodiment, the method comprises the following steps: the first electrical signal Singal1 includes a plurality of first level signals representing binary values constituting the first data signal and a second level signal representing the end of reading.
It is understood that the first level signal and the second level signal are level signals with different high-low level ratios. For example, the first level signal is a level signal having a ratio of high level to low level of N:1(N ≠ 1), and the second level signal is a level signal having a ratio of high level to low level of 1: 1.
It is understood that the external power supply apparatus starts reading from a first level signal when the external power supply apparatus recognizes the first level signal, and starts stopping reading when a second level signal is read. The first data signals are binary data, and all the first level signals may be specifically divided into high bits and low bits of the binary data, specifically, may be divided into high bits and low bits in an order of output order of the respective first level signals, or may be divided into high bits and low bits in an order of reverse order of output of the respective first level signals.
Optionally, when the main control circuit 110 outputs the control signal Vtrl1 according to the first data signal, the output steps are as follows:
1. when the data '1' is output, a level signal with the high level time length and the low level time length in a first preset proportion is output;
2. when the data '0' is output, a level signal with the high level time length and the low level time length in a second preset proportion is output;
3. when the data with the preset number of bits is continuously output, the level signal with the high level duration and the low level duration in a third preset proportion is output, wherein the data with the preset number of bits forms a first data signal, such as 8-bit binary data. The level signal of the third preset proportion represents the end of reading.
Referring to fig. 2, in one embodiment, the method includes:
when the ratio of the pulse width of the high level to the pulse width of the low level of the first level signal is a first preset proportion, the first data signal represented by the first electrical signal Singal1 is a binary value 0;
when the ratio of the pulse width of the high level to the pulse width of the low level of the first level signal is a second preset proportion, the first data signal represented by the first electrical signal Singal1 is a binary value 1;
the first preset proportion and the second preset proportion are reciprocal numbers.
Wherein Tc is a total duration of the first level signal, i.e. a time period, and a pulse width ratio of a high level to a low level of the first level signal is a ratio of a duration of the high level to the low level in a time period.
It is understood that the first preset ratio and the second preset ratio may be adjustable. For example, in one embodiment, the first preset ratio and the second preset ratio may be 1:3, 3:1, respectively, and in other embodiments, may also be 1:4, 4:1, and so on.
The carrier communication circuit 100 in this embodiment determines the first data signal represented by the first level signal by setting the pulse width ratio of the high level and the low level of the first level signal to a first preset ratio and a second preset ratio. Namely, the reliability of signal transmission is improved and the risk of external cracking is reduced through multiplying power coding and decoding.
In one embodiment, the pulse width of the first level signal is adjustable, i.e., the time width occupied by the first level signal is adjustable.
It will be appreciated that the adjustment of the pulse width of the first level signal does not affect the proportion of the high and low levels of the first level signal, and that by adjusting only the pulse width of the first level signal, an adjustment of the communication rate is achieved, for example, as the pulse width of the first level signal increases, the communication rate decreases, and as the pulse width of the first level signal decreases, the communication rate increases.
In one embodiment, the method comprises the following steps: the main control circuit 110 is further configured to receive a second electrical signal Singal2 sent by the external powered device 10 through the power line, and decode the second electrical signal Singal2 to obtain a second data signal.
It is understood that the master control circuit 110 obtains the communication data fed back by the external powered device 10 by encoding and decoding the received second electrical signal single 2.
