[0047] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0048] The following describes the stretching system and its energy flow control method and machine-readable storage medium according to the present application with reference to the accompanying drawings.

[0049] The tensioning system is used for the installation of power transmission lines and aerial ropeways, and includes a tension field 100 and a traction field 200. Both the tension field 100 and the traction field 200 are composed of a plurality of tensioning devices 10, a plurality of traction devices 20 and a plurality of auxiliary devices. The traction devices 20 are used for traction operations to pull power transmission lines (guide ropes / aerial ropeways), and the tensioning devices 10 provide tension for power transmission lines to tension the power transmission lines (guide ropes / aerial ropeways).

[0050] like Figure 1As shown, a specific embodiment of the present application provides an energy flow control method for a tensioning system, wherein the tensioning system includes a plurality of electric devices having a driving power source 1, wherein the plurality of electric devices include a traction device 20 and / or a tension device 10, and the energy flow control method includes:

[0051] Step S1: determining that the electric device whose driving power source 1 is in a power-deficient state is a device to be powered up;

[0052] Step S2: Determine that other electric devices other than the device to be powered and having a power supply module are power supply devices;

[0053] Step S3: Control the power supply module to charge the driving power supply 1 of the device to be powered.

[0054] It can be seen that in the specific embodiment of the present application, each electric device is powered by its own driving power supply 1, and each driving power supply 1 provides corresponding power according to the actual operating conditions of each electric device. Since the energy consumption of each electric device is different, after a long period of operation, the power of the driving power supply 1 of some electric devices will be lower than the actual required power, causing the driving power supply 1 of the electric device to be in a low-power state. The electric device whose driving power supply 1 is in a low-power state is a device to be powered on. If the driving power supply 1 of the device to be powered on is not charged in time, it will affect the operating efficiency of the device to be powered on.

[0055] At the same time, the driving power supply 1 of some electric devices may be higher than the actual power required, among which the electric devices with power supply modules and whose driving power supply 1 is not in a power-deficient state are power supply devices. In this application, the device to be powered and the power supply device are determined by the energy flow control method, and the power supply module of the power supply device is controlled to charge the driving power supply 1 of the device to be powered, thereby increasing the power of the driving power supply 1 of the device to be powered, and then realizing the reasonable allocation of energy to improve the operating efficiency of the tensioning system.

[0056] Furthermore, the use of electric motor drive to replace the traditional diesel engine drive of the traction equipment 20 and the tension equipment 10 is more conducive to the redistribution of energy and can reduce the noise pollution of the traction system. Electric energy, as a new energy source, also has the advantages of low pollution and low energy consumption.

[0057] In some embodiments, the traction device 20 includes a power generation mechanism 21, which can directly drive the motor of the traction device 20 to work and can also charge the driving power supply 1; the tension device 10 includes an energy recovery mechanism 11. Since the operating condition of the tension device 10 is a passive rotation condition, the energy recovery mechanism 11 can convert the kinetic energy generated by the passive rotation into electrical energy to charge the driving power supply 1.

[0058] In other words, the power supply module includes one or more of a driving power supply 1, a power generation mechanism 21 and an energy recovery mechanism 11, that is, the driving power supply 1 of the power supply device can directly charge the driving power supply 1 of the device to be powered, the power generation mechanism 21 of the power supply device can use the generated electric energy to charge the driving power supply 1 of the device to be powered, and the energy recovery mechanism 11 of the power supply device can directly use the recovered electric energy to charge the driving power supply 1 of the device to be powered.

[0059] It can be seen that in the specific embodiment of the present application, there are multiple parallel energy distribution schemes to achieve energy sharing of the entire tensioning system, thereby achieving rational use of energy and reducing energy consumption.

[0060] Furthermore, since the energy recovery mechanism 11 of the tension device 10 recovers too much energy and the capacity of the driving power supply 1 of the tension device 10 is limited, the excess energy needs to be processed ineffectively. Therefore, the energy recovery mechanism 11 is utilized to the maximum extent possible through energy sharing of the tensioning system, thereby improving energy utilization and achieving the purpose of energy saving and consumption reduction.

[0061] As for the specific working principles of the power generation mechanism 21 and the energy recovery mechanism 11, they are well known to those skilled in the art and are not part of the core improvement of this application, so they will not be described here. It should also be noted that the charging method of the driving power supply 1-driving power supply 1, the power generation mechanism 21-driving power supply 1, and the energy recovery mechanism 11-driving power supply 1 is based on the tensioning system using the driving power supply 1 and the motor drive method. At present, only when electric energy is used as the main energy form can the mutual transmission of energy be realized.

[0062] In some embodiments, step S1 comprises:

[0063] Step S11: obtaining the power of the driving power source 1 of the electric device;

[0064] Step S12: determining that the driving power source 1 whose power is less than or equal to the second threshold is in a power-deficient state;

[0065] Step S13: determining that the electric device whose driving power source 1 is in a power-deficient state is a device to be powered up;

[0066] The second threshold is a power-deficient state determination threshold.

[0067] In some embodiments, step S2 comprises:

[0068] Step S21: Determine that the driving power supply 1 with a power level greater than a second threshold is in a normal state;

[0069] Step S22: confirming that the electric device whose driving power source 1 is in a normal state has a power supply module;

[0070] Step S23: Determine that the electric device whose driving power source 1 is in a normal state and has a power supply module is a power supply device.

[0071] Through steps S1 and S2, it is possible to determine the power-supplyable devices and the devices to be powered in the tensioning system, and that the power-supplyable devices have one or more of the driving power source 1, the power generation mechanism 21 and the energy recovery mechanism 11, but it is not certain which one or which ones of the driving power source 1, the power generation mechanism 21 and the energy recovery mechanism 11 are charged and the charging priority.

[0072] In order to determine the specific power supply module, in some embodiments, step S3 includes:

[0073] Step S31: confirming that the driving power source 1 of the power-supply-capable device whose power supply amount is greater than a first threshold is a power-supply-capable module;

[0074] Step S32: controlling the driving power source 1 with a power level greater than the first threshold to charge the driving power source 1 of the device to be charged.

[0075] Specifically, step S31 and step S32 are specific steps for determining whether the driving power supply 1 of the power-supplyable device can be used as a power-supplyable module, wherein the first threshold is a threshold for determining whether external power supply can be provided. In other words, if the power of the driving power supply 1 of the power-supplyable device is less than or equal to the first threshold, the driving power supply 1 can only maintain the normal operation of the power-supplyable device. Only if the power of the driving power supply 1 of the power-supplyable device is greater than the first threshold can the driving power supply 1 maintain the normal operation of the power-supplyable device and transmit the excess power to the driving power supply 1 of the device to be powered. It can be seen that the energy flow control method of the present application will not affect the normal operation of the power-supplyable device and has a high rationality.

[0076] In some embodiments, step S3 comprises:

[0077] Step S31': confirming that the power of the driving power source 1 is greater than a third threshold and that the energy recovery mechanism 11 of the power supply device having the energy recovery mechanism 11 is a power supply module;

[0078] Step S32 ′: controlling the energy recovery mechanism 11 to charge the driving power source 1 of the device to be charged.

[0079] Specifically, step S31' and step S32' are specific steps for determining whether the energy recovery mechanism 11 of the powerable device with the energy recovery mechanism 11 can be used as a powerable module, wherein the third threshold is a full-charge state determination threshold. In other words, if the power of the driving power supply 1 of the powerable device with the energy recovery mechanism 11 is less than or equal to the third threshold, the driving power supply 1 cannot reach the full-charge state. Only when the power of the driving power supply 1 of the powerable device with the energy recovery mechanism 11 is greater than the third threshold, the driving power supply 1 reaches the full-charge state, so that the electric energy generated by the energy recovery mechanism 11 cannot continue to charge the driving power supply 1 and the excess electric energy is transmitted to the driving power supply 1 of the device to be powered. It can be seen that the energy flow control method of the present application preferentially recovers the electric energy generated by the energy recovery mechanism 11 of the powerable device with the energy recovery mechanism 11 into the driving power supply 1 of the powerable device, and has a high rationality.

[0080] In some embodiments, controlling the power supply module to charge the driving power supply 1 of the device to be powered includes:

[0081] Step S31″: confirming that the power generation mechanism 21 of the power supply device having the power generation mechanism 21 is a power supply module;

[0082] Step S32 ”: controlling the power generation mechanism 21 to charge the driving power source 1 of the device to be powered.

[0083] In fact, the available energy in the entire tensioning system continuously decreases with the operation of the electric equipment, while the power generation mechanism 21 can increase the available energy in the tensioning system. It can be seen that the energy flow control method of the present application can supplement energy to maintain the normal operation of the tensioning system when the available energy of the entire tensioning system is insufficient.

[0084] The above three power supply modules can charge the driving power supply 1 of the device to be powered separately or simultaneously.

[0085] In addition to the above-mentioned method of charging the driving power supply 1 of the device to be powered by the power supply module of the power supplyable device, in some embodiments, the energy flow control method also includes: determining that the device to be powered has an energy recovery mechanism 11, and controlling the energy recovery mechanism 11 of the device to be powered to charge the driving power supply 1 of the device to be powered; determining that the device to be powered has a power generation mechanism 21, and controlling the power generation mechanism 21 of the device to be powered to charge the driving power supply 1 of the device to be powered.

[0086] Specifically, the energy recovery mechanism 11 of the device to be powered that has an energy recovery mechanism 11 will continuously charge the driving power supply 1 of the device to be powered, and the power generation mechanism 21 of the device to be powered that has a power generation mechanism 21 will continuously charge the driving power supply 1 of the device to be powered. In other words, both the energy recovery mechanism 11 and the power generation mechanism 21 have self-charging functions. It can be seen that the energy flow control method of the present application can not only realize the energy replenishment between multiple electric devices, but also realize the self-energy replenishment of electric devices, and has high practicality.

[0087] Preferably, the various implementations of step S3 and the self-charging methods of the electric device all have priorities to increase the rationality of the energy flow control method, and the reasonable setting of the priorities of the various implementations is also conducive to the automatic execution of the energy flow control method, thereby improving the automation of the tensioning system. The priority is explained below, where the electric device with the energy recovery mechanism 11 is the tensioning device 10, and the electric device with the power generation mechanism 21 is the traction device 20.

[0088] First, the power level of the driving power source 1 of each tension device 10 is compared with the third threshold value. If there is a tension device 10 whose driving power source 1 power level is greater than or equal to the third threshold value, the energy recovery mechanism 11 of the tension device 10 will replenish the recovered energy to the driving power source 1 of the device to be replenished.

[0089] Secondly, when there is no tension device 10 whose driving power source 1 has a power greater than or equal to the third threshold, the power of the driving power source 1 of each power-supplying device is compared with the second threshold. If there is a power-supplying device whose driving power source 1 has a power greater than the second threshold, the driving power source 1 of the power-supplying device charges the driving power source 1 of the device to be charged;

[0090] Finally, when there is no device that can be powered and whose driving power source 1 has a power supply amount greater than the second threshold, the power generation mechanism 21 is started to charge the driving power source 1 of the device to be powered.

[0091] In a specific embodiment of the present application, a first threshold value is mentioned as a threshold value for determining whether external power supply is possible, a second threshold value is mentioned as a threshold value for determining a power-deficient state, and a third threshold value is mentioned as a threshold value for determining a fully charged state, wherein the third threshold value is greater than the first threshold value, and the second threshold value is less than the first threshold value. The device to be supplemented is determined by the second threshold value, the third threshold value is used to determine whether the energy recovery mechanism 11 of the tension device 10 can charge the device to be supplemented, and the first threshold value is used to determine whether the driving power supply 1 with a higher power of the device that can be supplied can charge the device to be supplemented, thereby realizing energy flow control of each electric device in the traction system, and then realizing reasonable utilization and allocation of energy to improve the operating efficiency of the tensioning system.

[0092] like Figures 2 to 4As shown, the specific embodiment of the present application also provides a stretching system, which implements the above-mentioned energy flow control method. Since the stretching system adopts all embodiments of the energy flow control method, the stretching system has all the beneficial effects brought by the energy flow control method.

[0093] In some embodiments, the stretching system includes a power management module, which is electrically connected to the plurality of electric devices and configured as follows:

[0094] Determine that the electric device whose driving power source 1 is in a power-deficient state is a device to be powered up;

[0095] Determine that other electric devices with power supply modules other than the device to be powered are power supply devices;

[0096] The power supply module is controlled to charge the driving power supply 1 of the device to be powered.

[0097] Preferably, the power management module is configured as follows:

[0098] Obtaining the power of a driving power source 1 of an electric device;

[0099] Determining that the driving power supply 1 whose power is less than or equal to the second threshold is in a power-deficient state;

[0100] The electric device whose driving power source 1 is determined to be in a power-deficient state is a device to be powered up.

[0101] Preferably, the power management module is configured as follows:

[0102] Determining that the driving power supply 1 with a power level greater than a second threshold is in a normal state;

[0103] Confirm that the electric device with the driving power supply 1 in a normal state has a power supply module;

[0104] It is determined that the electric device whose driving power source 1 is in a normal state and has a power supply module is a power supply device.

[0105] Preferably, the power management module is configured as follows:

[0106] Confirm that the driving power source 1 of the power-supply-capable device whose power supply amount is greater than the first threshold is a power-supply-capable module;

[0107] The driving power source 1 whose power level is greater than the first threshold is controlled to charge the driving power source 1 of the device to be powered.

[0108] Preferably, the power management module is configured as follows:

[0109] Confirm that the power of the driving power source 1 is greater than a third threshold value and that the energy recovery mechanism 11 of the power supply device having the energy recovery mechanism 11 is a power supply module;

[0110] The energy recovery mechanism 11 is controlled to charge the driving power source 1 of the device to be powered.

[0111] Preferably, the power management module is configured as follows:

[0112] Confirm that the power generation mechanism 21 of the power supply device having the power generation mechanism 21 is a power supply module;

[0113] The power generation mechanism 21 is controlled to charge the driving power source 1 of the device to be powered.

[0114] Preferably, the power management module is configured as follows:

[0115] It is determined that the device to be powered has an energy recovery mechanism 11, and the energy recovery mechanism 11 of the device to be powered is controlled to charge the driving power supply 1 of the device to be powered.

[0116] Preferably, the power management module is configured as follows:

[0117] It is determined that the device to be powered has a power generation mechanism 21, and the power generation mechanism 21 of the device to be powered is controlled to charge the driving power source 1 of the device to be powered.

[0118] In the present application, the above-mentioned energy flow control method is implemented by setting up a power management module, thereby realizing the automation of energy distribution in the traction system, wherein the first threshold, the second threshold and the third threshold can be pre-set, and the judgment conditions for the execution of each step are set to distinguish the priority of each step.

[0119] In some embodiments, a plurality of electric devices have a DC bus port 2 , and the plurality of DC bus ports 2 are interconnected, so that the power supply module can charge the driving power supply 1 of other electric devices through the DC bus port 2 .

[0120] Specifically, the driving power supply 1 of the device that can supply power charges the driving power supply 1 of the device to be powered through the DC bus port 2; the energy recovery mechanism 11 of the device that can supply power charges the driving power supply 1 of the device to be powered through the DC bus port 2; the power generation mechanism 21 of the device that can supply power charges the driving power supply 1 of the device to be powered through the DC bus port 2.

[0121] Furthermore, each electric device has its own DC bus port 2, and the DC bus ports 2 of different electric devices can be connected as needed to achieve energy sharing. In other words, during actual construction operations, if the traction field 200 and the tension field 100 are far apart, only the traction devices 20 and the tension devices 10 in the same traction field 200 are connected, or only the traction devices 20 and the tension devices 10 in the same tension field 100 are connected, thereby achieving energy sharing among the electric devices in the traction field 200 or energy sharing among the electric devices in the tension field 100, thereby improving the practicality of the traction system.

[0122] Preferably, a DC / DC transformer is connected between the power supply module and the DC bus port 2. Since the power of the driving power supply 1 of different electric devices is different, the voltage of the driving power supply 1 of different electric devices is different. When the driving power supply 1 of the power supply device is used as the power supply module to charge the driving power supply 1 of the device to be charged, the voltage is made the same by setting a DC / DC transformer, thereby avoiding damage to the driving power supply 1, thereby improving the practicality of the tensioning system.

[0123] In some embodiments, the tensioning device 10 and the traction device 20 both have a DC charging port 3, and the tensioning system also includes a DC charging device that can be connected to the DC charging port 3, and the DC charging device charges the driving power supply 1 through the DC charging port 3; the tensioning device 10 and the traction device 20 both have an AC charging port 4, and the tensioning system also includes an AC charging device that can be connected to the AC charging port 4, and the AC charging device charges the driving power supply 1 through the AC charging port 4.

[0124] In fact, the energy of the entire tensioning system will continue to decrease during the operation. In other words, if there is no external energy supplement entering the tensioning system, the driving power supply 1 of each electric device will be in a power-deficient state. Although the traction device 20 includes a power generation mechanism 21 capable of generating electricity, the power generation efficiency of the power generation mechanism 21 is low and will cause environmental pollution. Therefore, the driving power supply 1 of each electric device is charged by providing a DC charging port 3 to connect to a DC charging device and by providing an AC charging port 4 to connect to an AC charging device.

[0125] However, the installation of AC charging equipment and DC charging equipment is limited by site conditions, and in most cases the conditions for installation are not available. Therefore, energy sharing among various electric devices in the tensioning system through the DC bus port 2 is highly practical and economical, and is applicable to all site conditions.

[0126] In some embodiments, the tension device 10 and the traction device 20 both have an AC discharge port 5, and the tensioning system also includes an accessory device that can be connected to the AC discharge port 5. The driving power supply 1 discharges to the accessory device through the AC discharge port 5, and the accessory device includes a wire crimping machine, lighting equipment, etc.

[0127] Preferably, the power management module includes a power management unit 6, a manual operator and a controller 7 respectively arranged on each electric device.
