As shown in fig. 1, the method for detecting a dual-network-port cascade power supply includes:
s110, acquiring a first detection point voltage and a second detection point voltage; the first detection point is connected with a first internet access; the second detection point is connected with a second network port;
in the scheme, a plurality of devices are powered in a double-network-port cascading mode, namely, not only network signals and data but also power signals are transmitted among network cables. Usually, a power supply is connected to a first device, and then the devices which are cascaded are only connected in series through a network cable, and can normally operate without a separate external power adapter.
Exemplarily, fig. 2 is a schematic diagram of a device cascade connection mode provided in an embodiment of the present application, and as shown in fig. 2, N devices are cascaded, where any network port of a first device is connected to a switch and a dc power adapter, and another network port is connected out through a network cable and directly connected to any network port of a next device. The latter equipment is only required to be sequentially and directly connected to the Nth equipment through a network cable. According to the signal definition of 8 pins at the network port, the pins 1, 2, 3 and 6 are used for transmitting data, the remaining four pins are used as a pair of positive power supply and a pair of negative power supply, for example, the positive pole of the adapter is connected to the pins 4 and 5, the negative pole is connected to the pins 7 and 8, and the pins 1, 2, 3 and 6 are connected to the switch. The latter equipment is only required to be sequentially and directly connected to the Nth equipment through a network cable.
In this embodiment, N devices are cascaded through a network port, and each device includes two network ports, i.e., a first network port and a second network port. A detection control circuit is designed in each device, and the detection control circuit is composed of a control unit and a detection unit. The detection unit is used for measuring the equivalent impedance of the equipment at the later stage, namely whether the equipment at the later stage has a fault. The control unit is controlled by the detection unit, and the executed function depends on the detection result of the detection unit.
For example, fig. 3 is a schematic structural diagram of a detection unit provided in an embodiment of the present application, and as shown in fig. 3, the detection unit inside the device is composed of a load detection module, an ADC (analog-to-digital conversion) module, an MCU (micro control unit), two detection switches K2 and K3, and four voltage dividing resistors. The point A is a first detection point, and the point B is a second detection point. The ADC module is used for detecting the voltage on the voltage dividing resistor; the MCU is used for controlling the closing of the detection switch; the load detection module is used for calculating the load impedance of the subsequent equipment.
Preferably, two divider resistors are respectively arranged to be connected with the first network port and the second network port, and the detection point is arranged between the two divider resistors. A plurality of divider resistors can be respectively arranged to be connected with the network ports. The number of the voltage dividing resistors and the positions of the detection points can be set according to the connection requirements of the dual-network-port cascade equipment.
In this embodiment, optionally, the obtaining the voltage of the first detection point and the voltage of the second detection point includes:

S120, determining a receiving port network port and a power supply port network port from the first network port and the second network port according to the first detection point voltage and the second detection point voltage;
in this embodiment, the present apparatus includes a first network port and a second network port, one of the two network ports is a power supply port, and the other is a power receiving port. The power supply port and the power receiving port can be judged according to the voltage of the detection point.

and if the voltage of the first detection point is less than the voltage of the second detection point, determining that the first network port of the current device is a power receiving network port and the second network port is a power supply network port.
In the scheme, the receiving port and the power supply port can be determined by comparing the voltages of the first detection point and the second detection point. Generally, the voltage of the power supply end is greater than that of the power receiving end during normal power-on, and a situation of voltage false detection caused by incomplete release of the power supply voltage may exist after rapid power-on and power-off, so that a certain time delay can be set, for example, one or two seconds, and then the magnitude relation between the voltage of the first detection point and the voltage of the second detection point is detected and compared. When the voltage of the first detection point is greater than the voltage of the second detection point, or the voltage of the first detection point detected for the first time is less than the voltage of the second detection point, and the voltage of the first detection point detected for the second time is greater than the voltage of the second detection point, the second network port is determined to be a power receiving network port; and when the voltage of the second detection point is greater than the voltage of the first detection point, or the voltage of the first detection point is less than the voltage of the first detection point, and the voltage of the second detection point is greater than the voltage of the first detection point, the first network port is determined to be the power receiving network port.

Wherein the threshold constraint condition may be that the load impedance is smaller than an impedance criterion value. The magnitude of the standard impedance value can be set according to the condition of the cascade equipment circuit.
In the scheme, if the rear-stage link has a fault, the current device cannot supply power to the device of the rear-stage link, and at this time, the calculated load impedance value of the rear-stage link is small. Whether the rear-stage link has a fault can be judged by comparing the load impedance with the impedance standard value. The failure of the rear link may be a short-circuit failure or a failure not meeting a power supply condition.
In this technical solution, optionally, the detection switch is controlled to be closed based on the receiving end network port, and the load impedance of the rear link of the receiving end network port is calculated based on the load detection module.
In this embodiment, if the receiving port is the first port, the detection switch K2 is controlled to be closed based on the MCU to form the detection loop 1, and the load impedance of the subsequent link of the receiving port is calculated based on the load detection module. If the receiving end network port is the second network port, the detection switch K3 is controlled to be closed based on the MCU to form a detection loop 2, and the load impedance of the rear-stage link of the receiving end network port is calculated based on the load detection module. Wherein, the power supply port is the power supply input end.
For example, fig. 4 is a schematic diagram of a detection circuit provided in the first embodiment of the present application. As shown in fig. 4, the loop 1 and the loop 2 are both detection loops of a back-stage link device, and the load impedance of the back-stage link of the power receiving port can be calculated by the load detection module.
By calculating the load impedance, whether the cascade link has a fault or not can be detected, so that the normal power supply of the preceding link of the short-circuit fault equipment is maintained.

In this scheme, the standard voltage constraint condition may be set according to the number of cascaded devices. When a plurality of cascaded devices are available, the problem that the state of the device is unstable or the device cannot be started due to too low rear-stage input voltage is inevitable, and a standard voltage VS can be set at the moment and compared with the detected voltage of the network port of the power supply terminal. And controlling the connection or disconnection of the power supply link of the internal network port of the current equipment by the control unit. The stability of power supply of the cascade link can be guaranteed, and the number of cascade devices can be accurately controlled.
