In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
the device sampling apparatus in this embodiment is used for sampling the current of the power line of the sampled device in an electromagnetic induction manner so as to realize the data sampling of the sampled device, and is also used for taking electricity from the power line of the sampled device in an electromagnetic induction manner, and immediately using the taken electric energy for self power supply and self power supply after storage. The embodiment provides a management method of an equipment sampling device, which can comprise the following steps:
s101, obtaining decision data, wherein the decision data at least comprises current energy related data sent by an equipment sampling device in a wireless communication mode, the energy related data at least comprises characteristic data used for representing the current power supply capacity of the equipment sampling device, and the power supply capacity comprises electromagnetic induction electricity taking capacity and electric energy reserve capacity;
s102, generating energy management data according to preset rules and the decision data;

The decision data in S101 may further include: at least one of the characteristic attribute of the sampled device and the sampling service requirement becomes a factor influencing energy management data, and the data is used for determining the energy management data by combining the current energy related data of the device sampling device acquired in a wireless communication mode as decision data. For example, if the device to be sampled belongs to a device with low precision, or the requirement on the accuracy of the current sampling service is not high, the data sampling frequency and the wireless data outgoing frequency of the device sampling apparatus may be relatively low, and energy management data for reducing the data sampling frequency and the wireless data outgoing frequency of the device sampling apparatus may be generated.
The energy related data in S101 may further include: and when the energy source related data also comprises the power consumption influence data of the equipment sampling device, the decision data also comprises the power consumption influence data of the equipment sampling device because the decision data at least comprises the energy source related data. The power consumption influence data of the equipment sampling device also becomes one of the factors influencing the energy management data. The data type included in the power consumption influence data is described below.
The feature data in S101 may include: at least one of heartbeat messages, current power taking power, current power taking electric energy, current power taking electric quantity, current power storage electric energy and current power storage electric quantity under the condition of power off can be used as characteristic data. The power supply capacity comprises electromagnetic induction electricity taking capacity and electric energy reserve capacity. That is to say, the data capable of representing the current electromagnetic induction electricity taking capability or the electric energy reserve capacity of the device sampling device can be used as characteristic data.

After the power supply is disconnected (for example, the power supply is cut off by the power line of the sampled device), the device sampling apparatus may send a heartbeat message to the management platform in a wireless communication manner by means of the reserved power. Theoretically, it is preferable to continuously send the heartbeat message, and the heartbeat message can be kept in contact with the management platform all the time, but in order to recover the power supply, data sampling is started at the fastest speed, and the reserved energy is needed when the data sampling is started, so, preferably, after the power supply is cut off, the frequency and the frequency of sending the heartbeat message are controlled, a lower limit amount is reserved, for example, 2 heartbeat messages are sent every day and are sent for 30 days in total, and if the battery power is less than 90%, the heartbeat message is stopped being sent.
