In the embodiment of the present application, the current detection device 100 is communicatively connected to the platform 200. The current detection device 100 is configured to be disposed at a location where the first device 300 is located, detect a working current of the first device 300, convert the working current into a reference value, and send the current reference value to the platform 200 when it is determined that the working current of the first device 300 meets a preset condition according to the reference value. The platform end 200 receives the reference value, and determines the current operation state of the first device 300 or outputs alarm information according to the type of the interval to which the reference value belongs. Sending information including the identity of the current detection apparatus 100 and the current reference value to the client

Optionally, the platform side 200 has a database. The database stores first device 300 account information and identity information of the current detection apparatus 100, and the first device 300 account information is associated with the identity information of the corresponding current detection apparatus 100.

One embodiment of the present application provides a current detection apparatus 100, as shown in fig. 1 and 3, including a control module 1 and a current collection module 2.

The current collection module 2 is configured to be disposed near the power line 301 of the first device 300 in a non-contact manner, and the control module 1 is electrically connected to the current collection module 2.

The current collection module 2 is used for sensing the working current of the first device 300 and converting the working current into a reference value.

The control module 1 is configured to receive the reference value, and when it is determined that the working current of the first device 300 meets the preset condition according to the reference value, send the current reference value to the platform end 200, so that the platform end 200 determines the current operation state of the first device 300 or outputs alarm information according to the type of the interval to which the reference value belongs.

The current in the power line 301 of the first device 300 is the working current of the first device 300, and the current collecting module 2 may generate an induced current according to the working current of the first device 300 according to the electromagnetic induction principle. The current collection module 2 has an analog-to-digital conversion function, and converts the induced current into a reference value (i.e., a digital signal). The working current, the induced current and the reference value of the first device 300 have a predetermined conversion relationship, and when the working current changes, the induced current and the reference value also change correspondingly. Therefore, the control module 1 can determine the operating current of the first device 300 according to the reference value.

The preset condition to be satisfied by the operating current of the first device 300 may be whether the variation amount of the operating current exceeds a current variation threshold, or whether the operating current exceeds a rated current value. Of course, other preset conditions may be set as desired.

In an embodiment of the present application, a worker may set a preset condition at the platform end 200, for example, the worker may input or select a specific value range of the current variation threshold and/or the rated current value, and the platform end 200 sends information of the preset condition set by the worker to the current detection device 100 for storage. Of course, the platform end 200 may also send and store information of default preset conditions to the current detection device 100.

In the current detection apparatus 100 for device status according to the embodiment, the current collection module 2 is disposed near the power line 301 of the first device 300 in a non-contact manner, so that a failure of the first device 300 due to a defect of the current collection module 2 is avoided, and potential safety hazards of the first device 300 are reduced. Through information interaction, the control module 1 and the platform end 200 can determine the current operation state of the first device 300 or output alarm information in time, so that a worker can know the operation condition of the first device 300 in real time or know the alarm information, and can take corresponding measures to guarantee the normal operation of the first device 300 in time.

Moreover, the monitoring device does not autonomously cut off the power supply of the first device 300, thereby ensuring the power stability of the first device 300 and further reducing the potential safety hazard.

In one embodiment of the present application, the current collection module 2 includes a current transformer 21 and a signal conversion unit 22.

The current transformer 21 is configured to be disposed in a non-contact manner near the power line 301 of the first device 300, and the signal converting unit 22 is electrically connected to the current transformer 21 and the controller, respectively.

The current transformer 21 is used to generate an induced current according to the operating current of the first device 300.

The signal conversion unit 22 is configured to receive the induced current and convert the induced current into a reference value.

The current transformer 21 generates an induced current of a corresponding magnitude according to the magnitude of the current in the power line 301 of the first device 300 according to the principle of electromagnetic induction, and transmits the induced current to the signal conversion unit 22. The signal conversion unit 22 is configured to perform analog-to-digital conversion, generate a corresponding reference value according to the magnitude of the induced current, and send the reference value to the control module 1.

Alternatively, the number of current transformers 21 in the current collection module 2 may be configured according to the type of the operating power supply of the first device 300. The current collecting module 2 shown in fig. 1 may be applied to a first device 300 whose operating power source is two-phase electricity, for example, the operating voltage of the first device 300 may be 220V (volt) and the operating voltage may be 16A (ampere) or 10A. The current collection module 2 shown in fig. 3 may be applied to a first device 300 whose operating power source is three-phase power, for example, the operating voltage of the first device 300 may be 380V.

Alternatively, the first device 300 may be a medical device, and may also be a device in other fields.

In fig. 2, a line L is a Live line (Live) in the power line 301 of the first device 300, a line N is a Null line (Null) in the power line 301 of the first device 300, and a line E is a ground line (Earth) in the power line 301 of the first device 300. The current collection module 2 includes 1 current transformer 21, and the line L of the first device 300 is inserted into the current transformer 21, and the line L, the line N, and the line E are not in contact with the current transformer 21.

In fig. 4, line L1, line L2, and line L3 are the 3 live lines in the power cord 301 of the first device 300, and line N is the neutral line in the power cord 301 of the first device 300. The current collection module 2 includes 3 current transformers 21, and the line L1, the line L2, and the line L3 of the first device 300 are respectively inserted into the corresponding current transformers 21, and none of the line L1, the line L2, the line L3, and the line N contact the current transformers 21.

In an embodiment of the present application, when the control module 1 determines that the working current of the first device 300 meets the preset condition according to the reference value, the sending of the reference value to the platform end 200 includes:

the control module 1 determines the variation of the operating current of the first device 300 according to the previous reference value and the current reference value. If the variation exceeds the current variation threshold, the control module 1 sends the current reference value to the platform 200.

In an embodiment of the present application, when the control module 1 determines that the working current of the first device 300 meets the preset condition according to the reference value, the sending of the reference value to the platform end 200 includes:

the control module 1 determines the variation of the working current of the first device 300 according to the previous reference value and the current reference value; if the variation does not exceed the current variation threshold, the control module 1 sends the current reference value to the platform 200 at the preset time.

The control module 1 may receive the reference value output by the current collecting module 2 periodically. If the variation of the working current of the first device 300 does not exceed the current variation threshold, the control module 1 may periodically send a reference value to the platform 200; if the variation of the working current of the first device 300 exceeds the current variation threshold, the control module 1 will immediately send the reference value to the platform 200 even if the preset time is not reached.

The frequency at which the control module 1 receives and transmits the reference values may depend on the actual design requirements. For example, the control module 1 receives the reference value output by the current collection module 21 time every 1 second, and sends the reference value to the platform 200 1 time every 1 minute. If the variation of the operating current of the first device 300 does not exceed the current variation threshold, the control module 1 receives 60 reference values within one minute, and then sends the 60 reference values to the platform 200 at the same time. Of course, the frequency of receiving and transmitting the reference value by the control module 1 may be other values, for example, the control module 1 transmits the reference value to the platform end 200 every 2 minutes, and transmits 120 reference values each time.

Assuming that the control module 1 receives the reference value output by the current collection module 2 every 1 second for 1 time, when the control module 1 receives the reference value once in the 59 th second, the control module 1 determines the variation of the working current of the first device 300 according to the reference value received in the 58 th second and the reference value received in the 59 th second. If the control module 1 needs to send the reference value to the platform 200, the reference value received in the 59 th second is sent.

Alternatively, the staff may set a preset condition at the platform end 200, for example, the staff may input or select a specific numerical range of the current variation threshold, and the platform end 200 sends the information of the current variation threshold set by the staff to the current detection device 100 for storage. Of course, the platform end 200 may also send and store information of the default current variation threshold to the current detection device 100.

In an embodiment of the present application, when the control module 1 determines that the working current of the first device 300 meets the preset condition according to the reference value, the sending of the reference value to the platform end 200 includes:

the control module 1 determines the current working current of the first device 300 according to the current reference value; if the current working current exceeds the rated current value, the control module 1 sends the current reference value to the platform end 200.

The control module 1 may receive the reference value output by the current collecting module 2 at a fixed time, and the specific frequency of receiving the reference value may be determined according to actual design requirements. For example, the control module 1 receives the reference value output by the current collection module 21 time every 1 second, and receives the reference value 60 times in one minute.

Assuming that the control module 1 receives the reference value output by the current acquisition module 2 every 1 second for 1 time, and when the control module 1 receives the reference value once in the 59 th second, the control module 1 determines the current working current of the first device 300 according to the reference value received in the 59 th second; if the current working current exceeds the rated current value, the control module 1 sends the reference value received in the 59 th second to the platform end 200.

Alternatively, the operator may set a preset condition at the platform end 200, for example, the operator may input or select a specific numerical range of the rated current value, and the platform end 200 sends the information of the rated current value set by the operator to the current detection device 100 for storage. Of course, the platform end 200 may transmit and store information of the default rated current value to the current detection device 100.

In the current detection apparatus 100 provided in the embodiment of the present application, under the condition that the transmission frequency of the reference value set by the control module 1 is low, the control module 1 may also send the reference value in time when the variation of the operating current of the first device 300 does not exceed the current variation threshold or the current operating current of the first device 300 exceeds the rated current value, so as to reduce the delay of information sending.

In an embodiment of the present application, when the control module 1 determines that the operating current of the first device 300 meets the preset condition according to the reference value, the sending the current reference value to the platform end 200 includes: when determining that the working current of the first device 300 meets the preset condition according to the reference value, the control module 1 sends the current reference value and the identity information of the current detection apparatus 100 to the platform 200.

The platform end 200 receives the reference value and the identity information of the current detection apparatus 100. The platform end 200 determines a first device 300 corresponding to the current detection device 100 according to the identity information; according to the section type to which the reference value belongs, determining the operation state of the first device 300 corresponding to the current detection apparatus 100, or outputting alarm information of the first device 300 corresponding to the current detection apparatus 100.

Specifically, the platform 200 determines, according to the identity information of the current detection apparatus 100, the standing book information of the first device 300 associated with the identity information, thereby determining the first device 300 corresponding to the current detection apparatus 100.

The 4V dc power can be connected to the 4G module in the first communication unit 31 and the 3.3V dc power can be connected to other components or modules.

In one embodiment of the present application, as shown in fig. 1, the power module 4 further includes a battery 42, and the battery 42 is electrically connected to the second communication unit 32. The battery 42 can store electric energy, and when the voltage conversion unit 41 is disconnected from the external alternating current, the battery 42 supplies power to the second communication unit 32, so that the second communication unit 32 can normally realize the positioning function.

Alternatively, the battery 42 may employ a button battery.

Alternatively, the battery 42 may be a rechargeable battery, and the battery 42 may be electrically connected to the voltage conversion unit 41.

It should be noted that the current detection apparatus 100 shown in fig. 3 can be applied to a large-sized first device 300 (for example, the operating voltage is 380V), and the position of the first device 300 is relatively fixed, and the positioning function is generally not required, so that the battery 42 is not separately provided to supply power to the second communication unit 32.
