[0025] It is understood that this embodiment does not limit this. It is understood that Figure 1 The application scenarios are only for illustration and are not limited to this.
[0026] In traditional equipment management methods, passive RFID (Radio Frequency Identification) technology electronic tags or active RFID tags are mainly used to power passive devices to ensure interconnection and data transmission between devices. However, the power required by passive RFID technology electronic tags comes from the radio frequency energy sent by the reader antenna, and the communication distance is short, which cannot guarantee the effective transmission of data, resulting in low equipment management efficiency. Active RFID tags are mainly powered by batteries, but the battery capacity is very limited. Once the battery is out of power, it cannot guarantee the effective transmission of data, and frequent battery replacement will increase the cost of equipment management.
[0027] The device management method of the present application is to set a main power supply unit and a backup power supply unit in the passive device in the passive Internet of Things, wherein the main power supply unit includes an energy conversion subunit, and the backup power supply unit includes an energy supply subunit. The main power supply unit is used to convert the energy received by the passive device into electric energy to power the passive device based on the energy conversion subunit, and the backup power supply unit is used to power the passive device based on the electric energy provided by the energy supply subunit. Obtain the operating state influencing parameters of the passive device; based on the preset main and backup power switching strategy, select one of the main power supply unit and the backup power supply unit to power the passive device, so as to send the operating state influencing parameters to the device management server; the device management server is used to manage the passive device based on the operating state influencing parameters. Compared with the traditional device management method based on passive RFID electronic tags to power passive devices to support data transmission, the present application can overcome the shortcoming of short communication distance of passive RFID electronic tags by setting a main power supply unit that can convert the energy received by the passive device into electric energy, and a standby power supply unit that can directly power the passive device, and by selecting one of the main power supply unit and the standby power supply unit to power the passive device to support data transmission based on the main and standby power switching strategy, and can ensure the effective transmission of data, thereby improving the efficiency of device management. In addition, since the passive device is also provided with a main power supply unit that can convert the energy received by the passive device into electric energy, the data transmission of the device does not only rely on the standby power supply unit that can directly power the passive device, therefore, the use time of the standby power supply unit can be extended, and there is no need to frequently replace the power supply sub-units such as batteries, thereby reducing the cost of device management. In addition, after the capacity of the standby power supply unit is used up, the present application can also power the passive device through the main power supply unit to support data transmission, which can ensure the effective transmission of data, thereby improving the efficiency of device management.
[0028] In one embodiment, Figure 2As shown, a device management method is provided, which is applied to passive devices in a passive Internet of Things, wherein the passive device includes a main power supply unit and a backup power supply unit, wherein the main power supply unit includes an energy conversion subunit, and the backup power supply unit includes an energy supply subunit, wherein the main power supply unit is used to convert energy received by the passive device into electrical energy based on the energy conversion subunit to power the passive device, and the backup power supply unit is used to power the passive device based on the electrical energy provided by the energy supply subunit; the method comprises the following steps:
[0029] Step 202: Obtain operating status influencing parameters of the passive device.
[0030] In one embodiment, the operating state influencing parameters include device parameters of the passive device and environmental parameters of the area where the passive device is located. The device parameters may include configuration information and operating performance information of the passive device, and the operating performance information may specifically include at least one of voltage, availability information, and reliability information of the passive device. Environmental parameters may include at least one of temperature, humidity, and light in the area where the passive device is located. Environmental parameters may be acquired through sensors arranged on the passive device. For example, the temperature of the area where the passive device is located may be acquired through a temperature sensor arranged on the passive device, the humidity of the area where the passive device is located may be acquired through a humidity sensor arranged on the passive device, and the light in the area where the passive device is located may be acquired through a light sensor arranged on the passive device.
[0031] In one embodiment, Figure 3 As shown, in addition to the main power supply unit and the backup power supply unit, the passive device of the passive Internet of Things may also include a microprocessing unit and a communication unit, as well as a temperature sensor for collecting environmental parameters (used to collect the temperature of the area where the passive device is located), a humidity sensor (used to collect the humidity of the area where the passive device is located), and a light sensor (used to collect the light of the area where the passive device is located). Among them, the main power supply unit includes an energy conversion subunit and a first power control subunit. The backup power supply unit includes an energy supply subunit and a second power control subunit. The main power supply unit can convert the energy received by the passive device into electrical energy based on the energy conversion subunit to power the passive device. The backup power supply unit can power the passive device based on the electrical energy provided by the energy supply subunit. The first power control subunit is used to control the main power supply unit to power the passive device. The second power control subunit is used to control the backup power supply unit to power the passive device. The microprocessing unit is used to control the switching of the main and backup power supplies based on a preset main and backup power supply switching strategy. The communication unit is used to send the operating state influencing parameters of the passive device to the device management server.
[0032] Step 204, based on the preset main and backup power switching strategy, select one of the main power unit and the backup power unit to power the passive device, so as to send the operating status influencing parameters to the device management server; the device management server is used to manage the passive device based on the operating status influencing parameters.
[0033] In one embodiment, the operating state influencing parameters include device parameters of the passive device and environmental parameters of the area where the passive device is located. The passive device can select one of the main power supply unit and the backup power supply unit to power the passive device based on a preset main and backup power supply switching strategy, so as to send the device parameters and environmental parameters to the device management server. The device management server can receive the device parameters and environmental parameters sent by the passive device, and manage the passive device based on the device parameters and environmental parameters.
[0034] In one embodiment, Figure 4 As shown, the parameters affecting the operating status include the device parameters of the passive device and the environmental parameters of the area where the passive device is located. The passive device can select one of the main power supply unit and the backup power supply unit to power the passive device based on the preset main and backup power supply switching strategy, so as to send the device parameters and environmental parameters to the intermediate node (for example, a relay device, a common terminal or an amplifier), and the intermediate node sends the device parameters and environmental parameters to the base station, and the base station sends the device parameters and environmental parameters to the device management server. The device management server can receive the device parameters and environmental parameters sent by the passive device, and manage the passive device based on the device parameters and environmental parameters.
[0035] In one embodiment, the passive device can obtain the operating state influencing parameters of the passive device, and select the main power supply unit to power the passive device, so as to send the operating state influencing parameters to the device management server. In the case that the main power supply unit is used to power the passive device, resulting in a failure to send the operating state influencing parameters, the standby power supply unit is selected to power the passive device, so as to send the operating state influencing parameters to the device management server.
[0036] In the above device management method, a main power supply unit and a backup power supply unit are set in the passive device in the passive Internet of Things, the main power supply unit includes an energy conversion subunit, and the backup power supply unit includes an energy supply subunit. The main power supply unit is used to convert the energy received by the passive device into electrical energy to power the passive device based on the energy conversion subunit, and the backup power supply unit is used to power the passive device based on the electrical energy provided by the energy supply subunit. Obtain the operating state influencing parameters of the passive device; based on the preset main and backup power switching strategy, select one of the main power supply unit and the backup power supply unit to power the passive device, so as to send the operating state influencing parameters to the device management server; the device management server is used to manage the passive device based on the operating state influencing parameters. Compared with the traditional device management method based on passive RFID electronic tags to power passive devices to support data transmission, the present application can overcome the shortcoming of short communication distance of passive RFID electronic tags by setting a main power supply unit that can convert the energy received by the passive device into electric energy, and a standby power supply unit that can directly power the passive device, and by selecting one of the main power supply unit and the standby power supply unit to power the passive device to support data transmission based on the main and standby power switching strategy, and can ensure the effective transmission of data, thereby improving the efficiency of device management. In addition, since the passive device is also provided with a main power supply unit that can convert the energy received by the passive device into electric energy, the data transmission of the device does not only rely on the standby power supply unit that can directly power the passive device, therefore, the use time of the standby power supply unit can be extended, and there is no need to frequently replace the power supply sub-units such as batteries, thereby reducing the cost of device management. In addition, after the capacity of the standby power supply unit is used up, the present application can also power the passive device through the main power supply unit to support data transmission, which can ensure the effective transmission of data, thereby improving the efficiency of device management.
[0037] In one embodiment, based on a preset main-backup power supply switching strategy, one of the main power supply unit and the backup power supply unit is selected to power the passive device so as to send the operating status influencing parameters to the device management server, including: determining the power switching decision value according to the current transmission power parameter and the average transmission power parameter of the main power supply unit, and the priority parameter of the operating status influencing parameters; in the event that the use of the main power supply unit to power the passive device results in a failure to send the operating status influencing parameters, based on the power switching decision value, one of the main power supply unit and the backup power supply unit is selected to power the passive device so as to send the operating status influencing parameters to the device management server.
[0038] Among them, the current transmission power parameter is the current transmission power parameter of the main power supply unit. The average transmission power parameter is the average value of the transmission power parameter of the main power supply unit, and the average transmission power parameter is a constant. The priority parameter of the operating state influencing parameter is a parameter used to characterize the priority of sending the operating state influencing parameter. The importance of the operating state influencing parameter is positively correlated with the priority parameter. It can be understood that the more important the operating state influencing parameter is, the higher its priority of sending is.
[0039] Specifically, the passive device can obtain the operating state influencing parameters of the passive device, and select the main power supply unit to power the passive device, so as to send the operating state influencing parameters to the device management server. In the case that the main power supply unit is used to power the passive device, resulting in failure to send the operating state influencing parameters, the power switching decision value is determined according to the current transmission power parameter and the average transmission power parameter of the main power supply unit, and the priority parameter of the operating state influencing parameters, and based on the power switching decision value, one of the main power supply unit and the backup power supply unit is selected to power the passive device, so as to send the operating state influencing parameters to the device management server.
[0040] In one embodiment, the passive device may determine the ratio of the average transmission power parameter of the main power unit to the current transmission power parameter of the main power unit, and directly add the ratio to the priority parameter of the operating state influencing parameter, and use the added value as the power switching decision value. If the power switching decision value is greater than the preset decision value, the passive device may select the standby power unit to power the passive device to send the operating state influencing parameter to the device management server. If the power switching decision value is less than or equal to the preset decision value, the passive device may continue to try to use the main power unit to power the passive device to send the operating state influencing parameter to the device management server.
[0041] In the above embodiment, when the use of the main power supply unit to power the passive device results in a failure in sending the parameters affecting the operating status, based on the power switching decision value, one of the main power supply unit and the backup power supply unit is continued to be selected to power the passive device to send the parameters affecting the operating status to the device management server, which can ensure the effective transmission of the parameters affecting the operating status, thereby further improving the efficiency of device management.
[0042] In one embodiment, a power switching decision value is determined based on a current transmission power parameter and an average transmission power parameter of a main power unit, as well as a priority parameter of a parameter affecting the operating status, including: determining a ratio of an average transmission power parameter of the main power unit to a current transmission power parameter of the main power unit; performing a weighted summation of the ratio and a priority parameter of the parameter affecting the operating status to obtain a power switching decision value; based on the power switching decision value, selecting one of the main power unit and the backup power unit to power a passive device so as to send the parameter affecting the operating status to a device management server, including: if the power switching decision value is greater than a preset decision value, selecting the backup power unit to power the passive device so as to send the parameter affecting the operating status to the device management server; if the power switching decision value is less than or equal to the preset decision value, continuing to try to use the main power unit to power the passive device so as to send the parameter affecting the operating status to the device management server.
[0043] In one embodiment, the power switching decision value may be calculated by the following formula:
[0044] ;
[0045] Among them, N0 represents the average transmission power parameter of the main power supply unit, N1 represents the current transmission power parameter of the main power supply unit, N2 is the priority parameter of the operating status influencing parameter, and Y1 and Y2 are pre-set weight coefficients respectively.
[0046] In the above embodiment, if the power switching decision value is greater than the preset decision value, it means that the energy collected by the main power unit is insufficient to generate enough electric energy to power the passive device to support data transmission. At this time, the backup power unit can be selected to power the passive device, so that the operating status affecting parameters can be smoothly sent to the device management server. If the power switching decision value is less than or equal to the preset decision value, it means that the energy collected by the main power unit is sufficient to generate enough electric energy to power the passive device to support data transmission. At this time, you can continue to try to use the main power unit to power the passive device, so as to smoothly send the operating status affecting parameters to the device management server. While ensuring the smooth transmission of quantitative data, you can avoid activating the backup power unit and save the energy of the backup power unit, so that when the energy collected by the main power unit is insufficient, the passive device can be powered in time to ensure the normal transmission of data, further improving the efficiency of device management.
[0047] In one embodiment, the method further includes: if the number of attempts to use the main power supply unit to power the passive device exceeds a preset number, selecting a backup power supply unit to power the passive device to send the operating status influencing parameters to the device management server.
[0048] Specifically, the passive device can obtain the operating state influencing parameters of the passive device, and select the main power supply unit to supply energy to the passive device, so as to send the operating state influencing parameters to the device management server. In the case where the main power supply unit is used to supply energy to the passive device, resulting in failure to send the operating state influencing parameters, the passive device can determine the ratio of the average transmission power parameter of the main power supply unit to the current transmission power parameter of the main power supply unit, and perform weighted summation of the ratio and the priority parameter of the operating state influencing parameters to obtain the power switching decision value. If the power switching decision value is greater than the preset decision value, the standby power supply unit is selected to supply energy to the passive device, so as to send the operating state influencing parameters to the device management server; if the power switching decision value is less than or equal to the preset decision value, the main power supply unit is continued to be tried to supply energy to the passive device, so as to send the operating state influencing parameters to the device management server. If the number of attempts to use the main power supply unit to supply energy to the passive device exceeds the preset number, the passive device can select the standby power supply unit to supply energy to the passive device, so as to send the operating state influencing parameters to the device management server.
[0049] In the above embodiment, if the number of attempts to use the main power supply unit to power the passive device exceeds the preset number, the backup power supply unit is selected to power the passive device, so that the passive device can be powered in time to ensure normal data transmission, further improving the efficiency of device management.
[0050] In one embodiment, the device management server is further used to input the operating status influencing parameters into a pre-built digital twin model of the passive device, so that the digital twin model simulates the operating status of the passive device based on the operating status influencing parameters.
[0051] Among them, the digital twin model of passive equipment is a model obtained by three-dimensional dynamic modeling of passive equipment.
[0052] In one embodiment, the passive device may obtain the operating state influencing parameters of the passive device, and based on a preset main-standby power switching strategy, select one of the main power supply unit and the standby power supply unit to power the passive device, so as to send the operating state influencing parameters to the device management server. The device management server may receive the operating state influencing parameters sent by the passive device, and input the operating state influencing parameters into a pre-built digital twin model of the passive device, so that the digital twin model simulates the operating state of the passive device based on the operating state influencing parameters.
[0053] In the above embodiment, the operating status of the passive device is simulated by the digital twin model based on the operating status influencing parameters, so that real-time monitoring of the operating status of the passive device can be achieved, the operating status of the passive device can be understood in time, and the equipment management efficiency can be further improved.
[0054] In one embodiment, the device management server is further configured to issue an alarm message when the operating status influencing parameter exceeds an alarm threshold.
[0055] In one embodiment, the passive device may obtain the operating state influencing parameters of the passive device, and based on the preset main and standby power switching strategy, select one of the main power supply unit and the standby power supply unit to power the passive device, so as to send the operating state influencing parameters to the device management server. The device management server may receive the operating state influencing parameters sent by the passive device, and determine whether the operating state influencing parameters exceed the preset alarm threshold. In the case where the operating state influencing parameters exceed the alarm threshold, the device management server may issue an alarm message.
[0056] In one embodiment, the passive device can obtain the operating state influencing parameters of the passive device, and based on the preset main and standby power switching strategy, select one from the main power unit and the standby power unit to power the passive device, so as to send the operating state influencing parameters to the device management server. The device management server can receive the operating state influencing parameters sent by the passive device, and input the operating state influencing parameters into the pre-built digital twin model of the passive device, so that the digital twin model simulates the operating state of the passive device based on the operating state influencing parameters. In addition, the device management server can also determine whether the operating state influencing parameters exceed the preset alarm threshold. In the case where the operating state influencing parameters exceed the alarm threshold, the device management server can issue an alarm message.
[0057] In the above embodiment, when the operating status influencing parameter exceeds the alarm threshold, an alarm message is issued so that the operation and maintenance personnel can promptly handle abnormal situations that may occur or have occurred, thereby further improving the equipment management efficiency.
[0058] In one embodiment, Figure 5 As shown, the device management server includes a receiving unit, a model building unit, a display unit and an analysis unit. Among them, the receiving unit is used to receive the operating state influencing parameters sent by the passive device. The model building unit is used to build a digital twin model of the passive device. The display unit is used to input the operating state influencing parameters into the pre-built digital twin model of the passive device, so that the digital twin model simulates the operating state of the passive device based on the operating state influencing parameters, and sends the operating state information of the passive device to the display device for display. The analysis unit is used to determine whether the operating state influencing parameters exceed the preset alarm threshold. When the operating state influencing parameters exceed the alarm threshold, the device management server may issue an alarm message.
