For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In order to facilitate the understanding of the present application, the scheme of the present application is explained in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-3The present invention provides a movable cable branching detection device, which includes an outer shell 1, a plurality of cable plug-in interfaces 2 are installed on the outer shell 1, and a display panel 3 is installed on the outer wall of the outer shell 1; a plurality of electrical signal sensor groups and a control circuit board are installed in the inner cavity of the outer shell 1, and the plurality of electrical signal sensor groups are respectively installed at the cable plug-in interfaces 2, and the electrical signal sensor groups are electrically connected to the control circuit board, and the control circuit board is electrically connected to the display panel 3.

[0029] In this solution, when detecting the cable, the end of the cable can be inserted into the cable connection port 2. At this time, the electrical signal sensor group can collect electrical signals such as current, voltage, temperature and resistance on the cable, and transmit the electrical signals to the control circuit board. The control circuit board can receive the aforementioned electrical signals, analyze and process the detected electrical signals such as current, voltage, temperature and resistance, and display the electrical signals through the display panel 3.

[0030] The cable plug interface 2 may be a conventional interface adapted to a cable. The display panel 3 may be a conventional LED display panel or LCD display panel, which is not specifically limited in the present application.

[0031] In some embodiments, the electrical signal sensor group includes a current sensor 4, a voltage sensor 5, a temperature sensor 6 and a resistance sensor 7; the current sensor 4 adopts a Schneider Hall current sensor; the voltage sensor 5 adopts a CHV-25P Hall voltage sensor; and the temperature sensor 6 adopts a KG3007A.

[0032] In this solution, the current sensor 4 can detect the electrical signal of the current flowing through the cable. The voltage sensor 5 can detect the electrical signal of the voltage of the cable. The temperature sensor 6 can detect the electrical signal of the temperature on the cable. The resistance sensor 7 can detect the electrical signal of the resistance on the cable. In addition, the current sensor 4, the voltage sensor 5, the temperature sensor 6 and the resistance sensor 7 can transmit the electrical signals collected by each to the control circuit board, so that the control circuit board can analyze and process the electrical signals.

[0033] The control circuit board may be a control circuit board in the prior art, or a control circuit board in a non-prior art. For example:

[0034] When the control circuit board adopts the control circuit board in the prior art, specifically, a GEIS200WEMAH1AEA circuit board can be adopted.

[0035] This board is part of the General Electric Mark VI and Mark VIe control systems and is designed to perform signal termination and distribution functions. This board provides support between sensors, actuators and other peripheral devices.

[0036] When the control circuit board adopts a control circuit board not in the prior art, in some embodiments, a central processing unit 10, an electrical signal acquisition unit 11, an electrical signal optimization transmission unit 12, an alarm unit 13 and a storage unit 14 are installed on the control circuit board; the input end of the electrical signal acquisition unit 11 is respectively connected to the current sensor 4, the voltage sensor 5, the temperature sensor 6 and the resistance sensor 7, and the output end of the electrical signal acquisition unit 11 is connected to the central processing unit 10; the alarm unit 13 and the storage unit 14 are respectively connected to the central processing unit 10; the central processing unit 10 is connected to the background monitoring terminal 15 through the electrical signal optimization transmission unit 12.

[0037] In this solution, the electric signal acquisition unit 11 is used to obtain the electric signals collected by the current sensor 4, the voltage sensor 5, the temperature sensor 6 and the resistance sensor 7, and transmit the electric signals to the central processing unit 10. The central processing unit 10 is used to receive the electric signals transmitted by the electric signal acquisition unit 11, and analyze and process the electric signals. Among them, the processing of the electric signals by the central processing unit 10 includes storing the electric signals in the storage unit 14, and judging whether the electric signals are abnormal, and generating an alarm electric signal when it is determined that the electric signals are abnormal, sending the alarm electric signal to the alarm unit 13, and sending it to the background monitoring terminal 15 through the electric signal optimization transmission unit 12.

[0038] Among them, the central processing unit 10, the electrical signal acquisition unit 11, the electrical signal optimization transmission unit 12, the alarm unit 13 and the storage unit 14 can be existing units, and these existing units can be integrated with the control circuit board.

[0039] In some embodiments, the electrical signal optimization transmission unit 12 adopts an optical fiber transmission module, which includes transistor A (1c), transistor B (2c) and transistor C (3c). The base of transistor A (1c) is respectively connected to one end of resistor A (1a) and the signal input end, the emitter is grounded, the collector is respectively connected to one end of resistor B (2a) and the base of transistor C (3c), the collector of transistor C (3c) is grounded, the emitter is respectively connected to the emitter of transistor B (2c) and the optical fiber transceiver 16, the base of transistor B (2c) is connected to one end of resistor B (2b), and the collector is respectively connected to one end of resistor C (3a) and the optical fiber transceiver 16.

[0040] Considering the instability of data transmission between the detection device and the background monitoring terminal 15, in this solution, the electrical signal optimization transmission unit is designed to be an optical fiber driving circuit built by triode devices instead of an integrated driving chip. This mode can be suitable for harsh environments, that is, when the environment of the connection between the central processor 10 and the background monitoring terminal 15 is poor, the connection between the three triodes and the optical fiber transceiver can also achieve stable transmission of electrical signals, further improving the detection efficiency.

[0041] In some embodiments, a display screen 8 and an alarm indicator light 9 are installed on the display panel 3 ; the display screen 8 is connected to a central processing unit 10 ; and the alarm indicator light 9 is connected to an alarm unit 13 .

[0042] In this solution, the central processor 10 can transmit the electrical signal to the display screen 8, and the display screen 8 can receive the electrical signal and display the electrical signal. The central processor 10 can also transmit the abnormal electrical signal to the alarm unit 13, and the alarm unit 13 can perform an alarm based on the abnormal electrical signal.

[0043] In some embodiments, 3-5 cable plug-in ports 2 are provided, and the sizes of the cable plug-in ports 2 are not consistent.

[0044] In this solution, 3-5 cable plug-in ports 2 with different diameters can facilitate the detection device to detect cables of different sizes. For example, thinner cables can be inserted into the cable plug-in port 2 with a smaller diameter for easy detection. Thicker cables can be inserted into the cable plug-in port 2 with a larger diameter for easy detection. In this way, the versatility of the movable cable branching detection device can be improved.

[0045] The present invention also provides a detection method for a movable cable branching detection device, which is used for the aforementioned movable cable branching detection device, and the method comprises the following steps:

[0046] A. First, insert the end of the cable to be tested into the cable plug-in port;

[0047] B. The current sensor, voltage sensor, temperature sensor and resistance sensor respectively collect the current, voltage, temperature and resistance electrical signals of the cable and transmit them to the electrical signal acquisition unit;

[0048] C. The electrical signal acquisition unit acquires the electrical signals of current, voltage, temperature and resistance, and transmits the acquired electrical signals to the central processing unit;

[0049] D. The central processing unit analyzes and processes the electrical signal, and when it determines that the electrical signal is abnormal, generates an alarm electrical signal, and sends the alarm electrical signal to the alarm unit and the background monitoring terminal;

[0050] E. The alarm unit executes an alarm based on the alarm electrical signal.

[0051] In summary, the present invention has a novel structural design and is easy to use. It can be directly plugged in and out to avoid safety accidents, can achieve better protection effects in terms of insulation, can display the real-time status of current, resistance and wiring on the cable, and also has a power-off function, which saves labor and time, increases maintenance efficiency, visualizes line parameters, shortens maintenance time, and allows the line status to be clearly seen, thereby improving production efficiency.
