[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] An embodiment of the present invention provides an unmanned equipment remote control system and method, which can solve the technical problems in the related art that humans manually obtain the remaining power status of the unmanned equipment through terminals such as mobile phones or computers, and wake up and charge the unmanned equipment through terminals such as mobile phones or computers when the remaining power is low, resulting in cumbersome operation and low intelligent control performance.

[0046] Figure 1 An embodiment of the present invention provides an unmanned equipment remote control system, comprising: a wake-up control device, a wake-up execution device, a battery, a vehicle controller, and an energy storage system.

[0047] The wake-up execution device, the vehicle controller, and the energy storage system are connected in sequence, the battery is connected to the energy storage system, and the wake-up control device is connected to the wake-up execution device, the battery, and the vehicle controller respectively, and is configured to: obtain the power of the battery, control the action of the wake-up execution device according to the power of the battery, and enable the vehicle controller to control the energy storage system to charge the battery.

[0048] An unmanned equipment remote control system according to an embodiment of the present invention includes a wakeup control device, a wakeup execution device, a battery, a vehicle controller, and an energy storage system. The wakeup execution device, the vehicle controller, and the energy storage system are connected in sequence, the battery is connected to the energy storage system, and the wakeup control device is connected to the wakeup execution device, the battery, and the vehicle controller, respectively. The wakeup control device is configured to obtain the battery power level and control the wakeup execution device to operate according to the battery power level, so that the vehicle controller controls the energy storage system to charge the battery. When the battery power level reaches a minimum remaining power level, the wakeup control device remotely wakes up and controls the wakeup execution device to operate, so that the vehicle controller controls the energy storage system to charge the battery. The battery power level can be automatically obtained at any time through the wakeup control device, eliminating the need for manual access to the device's stored power level through a terminal such as a mobile phone or computer. When the remaining power level is low, the wakeup control device automatically wakes up and controls the energy storage system to charge the battery, thereby simplifying the operation process and improving the intelligent performance of the remote control system.

[0049] As an optional implementation, in one embodiment of the invention, see Figure 2 and Figure 5 As shown, the wake-up control device includes: a first communication module, a first main control module, and a first acquisition module. The first communication module is connected to the remote control device and the first main control module, and is used to receive remote control instructions and transmit them to the first main control module. The first acquisition module is connected to the battery and the first main control module, and is used to collect the battery power and transmit it to the first main control module. The first communication module is used to receive remote wake-up control instructions or remote sleep control instructions. When the battery power reaches the minimum value of the remaining power, the first communication module receives the remote wake-up control instruction, then the first main control module remotely wakes up the vehicle controller and the energy storage system; when the first communication module receives the remote sleep control instruction, the first main control module remotely controls the vehicle controller and the energy storage system to sleep; the first main control module controls the energy storage system to charge the battery according to the battery power status collected by the first acquisition module, that is, controls the energy storage system to charge the battery when the battery power reaches the minimum value of the remaining power.

[0050] As an optional implementation, in one embodiment of the invention, see Figure 2 and Figure 3 As shown, the wake-up control device also includes: a first control module, a wake-up relay K1, and a sleep relay K2. The first control module is connected to the first main control module, and the wake-up relay K1 and the sleep relay K2 are respectively connected to the first control module. The first control module controls the wake-up relay K1 and the sleep relay K2 to be closed or disconnected according to the power of the battery. When the power of the battery reaches the minimum value of the remaining power or the first communication module receives a remote wake-up control instruction, the first control module controls the wake-up relay K1 to be closed, and then controls the wake-up execution device to wake up the vehicle controller, so that the energy storage system charges the battery; when the first communication module receives a remote sleep control instruction, the first control module controls the sleep relay K2 to be closed, and then controls the wake-up execution device to make the vehicle controller sleep.

[0051] As an optional implementation, in one embodiment of the invention, see Figure 3As shown, the wake-up execution device includes: a main relay coil K1B, a sub-relay coil K2B, a main relay contact K1A, and a sub-relay contact K2A. One end of the main relay coil K1B is connected to the wake-up relay K1, and the other end is connected to the main relay contact K1A. One end of the sub-relay coil K2B is connected to the sleep relay K2, and the other end is connected to the sub-relay contact K2A. The main relay coil K1B and the sub-relay coil K2B are attracted to control the main relay contact K1A and the sub-relay contact K2A to be closed. The main relay coil K1B and the main relay contact K1A, and the sub-relay coil K2B and the sub-relay contact K2A form two complete sets of magnetic latching relays. When the wake-up relay K1 is continuously closed for a time exceeding the minimum power-on control time of the magnetic latching relay, the main relay coil K1B, the sub-relay coil K2B, the main relay contact K1A, and the sub-relay contact K2A are all closed, and the battery is positive. The positive pole of the battery is connected to the positive pole of the power supply of the vehicle controller, and the negative pole of the battery is connected to the negative pole of the power supply of the vehicle controller. At this time, the vehicle controller is powered on and can control the energy storage system to charge the battery; when the continuous closing time of the dormant relay K2 exceeds the minimum power-on control time of the magnetic latching relay, the main relay coil K1B, the auxiliary relay coil K2B, the main relay contact K1A and the auxiliary relay contact K2A are all disconnected, and the positive pole of the battery is disconnected from the positive pole of the power supply of the vehicle controller. At this time, the vehicle controller is disconnected and can be controlled to sleep; in addition, by applying a pulse voltage signal to the attraction control end of the magnetic latching relay coil, the relay contact can be controlled to close, and by applying a pulse voltage signal to the disconnection control end of the magnetic latching relay coil, the relay contact can be controlled to disconnect. Since the magnetic latching relay adopts pulse control, it can overcome the disadvantage that traditional relays or contactors require continuous voltage signal control, avoid the jitter and interference of the control signal, and improve the reliability of the control system.

[0052] As an optional implementation, in one embodiment of the invention, see Figure 3As shown, the wake-up execution device also includes: a first diode D1 and a second diode D2, wherein the positive and negative electrodes of the first diode D1 are respectively connected to the main relay coil K1B and the sub-relay coil K2B, and the positive and negative electrodes of the second diode D2 are also connected to the main relay coil K1B and the sub-relay coil K2B. When the wake-up relay K1 is closed, the power supply voltage of the battery forms a loop with the main relay coil K1B, the first diode D1, the sub-relay coil K2B to the negative power supply electrode of the wake-up control device. The positive power supply electrode of the battery forms a loop with the main relay coil K1B, the second diode D2, the sub-relay coil K2B to the negative power supply electrode of the wake-up control device, and applies a pulse voltage signal to the pull-in control end of the main relay coil K1B and the sub-relay coil K2B, thereby controlling the closure of the main relay contact K1A and the sub-relay contact K2A. The first diode D1 and the second diode D2 are both freewheeling diodes, which are used to absorb the reverse electromotive force generated during the relay operation and improve the service life of the magnetic latching relay.

[0053] As an optional implementation, in one embodiment of the invention, see Figure 1 and Figure 3 As shown, the unmanned equipment remote control system also includes: a key switch, which is connected to the vehicle controller. When the key switch is closed, the vehicle controller controls the energy storage system to charge the battery. The key switch is a redundant setting for human intervention control and has the highest priority. The key switch is a multi-speed selection switch with ON, OFF, ACC and START gears. The key switch includes two sets of contacts, which are respectively connected to the vehicle controller. When the key switch is in a non-OFF position, the battery is connected to the vehicle controller through the key switch, the vehicle controller is awakened by power and can obtain the remaining power of the battery. The vehicle controller controls the energy storage system to charge the battery according to the remaining power of the battery.

[0054] As an optional implementation, in one embodiment of the invention, see Figure 4As shown, the vehicle controller includes: a second communication module, a second main control module, a second control module, and a second acquisition module. The second communication module is connected to the wake-up control device and the second main control module, and is used to receive remote control instructions and transmit them to the second main control module. The second control module is connected to the second main control module and the energy storage system. The second main control module is used to control the energy storage system to charge the battery. The second acquisition module is connected to the second main control module and the key switch, and is used to collect the gear status of the key switch and transmit it to the second main control module. When the second acquisition module collects that the key switch is in a non-OFF position, the battery is connected to the second main control module, so that the second main control module is powered on. The second main control module controls the energy storage system to charge the battery according to the battery power level. The second communication module is used to receive wake-up control instructions, sleep control instructions, and instructions for charging the battery from the wake-up control device to achieve remote communication and control.

[0055] As an optional implementation, in one embodiment of the invention, see Figure 1 As shown, the unmanned equipment remote control system also includes: high-voltage power distribution equipment and low-voltage power distribution equipment. The high-voltage power distribution equipment is connected to the vehicle controller, the energy storage system, and the high-voltage load. The vehicle controller controls the energy storage system to distribute power to the high-voltage load through the high-voltage power distribution equipment. The low-voltage power distribution equipment is connected to the high-voltage power distribution equipment and the low-voltage load of the vehicle controller. The vehicle controller controls the energy storage system to distribute power to the low-voltage load through the low-voltage power distribution equipment. When the vehicle controller is powered on and awakened, the vehicle controller can control the energy storage system to complete the system high-voltage power distribution output through the high-voltage power distribution equipment and complete the system low-voltage power distribution output through the low-voltage power distribution equipment, thereby realizing power distribution to the high-voltage load and the low-voltage load.

[0056] As an optional implementation, in one embodiment of the invention, see Figure 1 As shown, the unmanned equipment remote control system also includes: a voltage conversion device, which is connected to the high-voltage power distribution equipment and the battery, and is used to convert the high voltage of the high-voltage power distribution equipment into a low voltage and charge the battery. When the power of the battery reaches the minimum value of the remaining power, the vehicle controller is powered on and awakened, and the voltage of the energy storage system flows through the high-voltage power distribution equipment and is converted into a low voltage through the voltage conversion device and output to the battery, thereby charging the battery.

[0057] The present invention also provides a remote control method for unmanned equipment. Figure 5 As shown, the following steps are included:

[0058] Obtain the battery power, and wake up the execution equipment and vehicle controller according to the battery power, so that the energy storage system can charge the battery.

When the remaining power is low, the wake-up control device automatically wakes up and controls the energy storage system to charge the battery, thereby simplifying the operation process and improving the intelligent performance of the remote control system.
