[0043] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this solution will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, not all of them. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this solution.

[0044] The term "comprising" and any other variations thereof in the specification, claims, and accompanying drawings of this invention mean "including but not limited to," and are intended to cover a non-exclusive inclusion, not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.

[0045] The implementation of this disclosure will be described in detail below with reference to the specific accompanying drawings:

[0046] Figure 1 This is a schematic diagram of a food delivery robot control system provided in an embodiment of this disclosure. (Refer to...) Figure 1 The food delivery robot control system is applied to the food delivery robot and includes: voltage detection equipment, main power supply, backup power supply, camera equipment, power display, relays and control system;

[0047] The relays are connected to the main power supply, the backup power supply, and the control system respectively; the voltage detection device is connected to the main power supply and the control system respectively; the control system is configured to switch between the main power supply and the backup power supply by controlling the switching state of the relays.

[0048] The control system is connected to both the power display and the camera; the camera is positioned directly above the power display and is configured to collect the power readings from the power display.

[0049] In this embodiment, the voltage detection device may include a Hall effect-based voltage sensor or a linear optocoupler voltage detection circuit, etc. The voltage detection device is installed near the main power supply output terminal and directly connected to the positive and negative terminals of the main power supply via wires to collect the raw voltage signal. The main power supply can be a lithium battery pack, etc., and is located in the center of the robot chassis or near the drive motor. The backup power supply can be a supercapacitor bank, placed adjacent to the main power supply for easy relay switching.

[0050] The camera device can be a small, high-definition camera, such as one using a CMOS image sensor, which features low light sensitivity and high resolution, enabling it to clearly capture the readings on the power indicator. The camera is positioned directly above the power indicator and mounted on an adjustable stand for easy initial viewing angle calibration, ensuring the camera's field of view fully covers the power indicator's reading area.

[0051] The battery level indicator can be an LCD screen, intuitively displaying key information such as battery percentage and voltage. The indicator is installed in a prominent position on the robot's control panel or side, allowing staff to quickly access battery information during routine checks and maintenance. A light shield can also be installed. Electromagnetic relays, such as single-pole double-throw relays, can be used, positioned near the output terminals of the main and backup power supplies. The control system outputs high / low level signals to drive the relay coils. When the control system determines that a power switch is needed, it changes the output level, causing the relay contacts to actuate, achieving a rapid switch between main and backup power.

[0052] For example, a small high-definition camera reads the battery level from the power indicator and transmits this reading to the control system. A voltage sensor monitors the voltage at the main power supply output and transmits the detected voltage signal to the control system. The control system first converts the battery level reading into an analog signal, then compares the voltage signal and the battery level signal. When both the battery level signal and the voltage signal are higher than a reference battery level signal and a reference voltage signal, the main power supply is maintained. Otherwise, the relay contacts are switched to the backup power supply for operation.

[0053] As can be seen from the above, due to the large deviations in power supply display readings during the aging and frequent failure stages of the power supply, voltage detection equipment becomes crucial to ensuring stable operation. It monitors the main power supply voltage in real time, ensuring the control system has a true grasp of the power supply's status and effectively avoiding the risk of power outages caused by misjudgments of power levels.

[0054] The camera is positioned near the power display to collect readings, thus addressing potential data anomalies that may occur in complex restaurant environments. Whether it's electromagnetic interference, temporary component failures, or reading errors, the system can ensure accurate power information, thereby enabling it to regulate the robot's operation in an orderly manner.

[0055] The control system flexibly operates the relays based on accurate power monitoring results, quickly switching between main and backup power sources to ensure uninterrupted power supply for the robot during high-intensity food delivery tasks, thereby improving restaurant operational efficiency and providing customers with a better and faster service experience.

[0056] like Figure 2 As shown, in one embodiment of this disclosure, the control system includes:

[0057] The system includes a digital-to-analog converter, a first comparator, a second comparator, AND gates, NOT gates, and a data processing unit.

[0058] The data processing unit is connected to the output of the NOT gate, the relay, and the power display, respectively.

[0059] The non-inverting input of the first comparator is connected to the voltage detection device, the inverting input of the first comparator is used to receive the first reference value, and the output of the first comparator is connected to the first input of the AND gate.

[0060] The non-inverting input of the second comparator is connected to the digital-to-analog converter, the inverting input of the second comparator is used to receive the second reference value, and the output of the second comparator is connected to the input of the AND gate.

[0061] The output of an AND gate is connected to the input of a NAND gate.

[0062] The digital-to-analog converter is connected to the camera equipment.

[0063] In this embodiment, the first reference value can be set as the analog voltage signal corresponding to the lowest voltage value required for the main power supply to operate normally, and the second reference value can be set as the analog signal value corresponding to the lowest power level required to ensure the food delivery robot operates normally. The voltage detection device monitors the main power supply voltage in real time and transmits the analog voltage signal to the non-inverting input of the first comparator. The first comparator compares the analog voltage signal with the preset first reference value: if the analog voltage signal is higher than the first reference value, the first comparator outputs a high-level signal; if the analog voltage signal is lower than the first reference value, the first comparator outputs a low-level signal.

[0064] Simultaneously, the camera captures the reading from the power display, converts it into a digital signal via a digital-to-analog converter, and transmits it to the non-inverting input of the second comparator. The analog power signal corresponding to the power reading is compared with a preset second reference value. If the analog power signal is higher than the second reference value, the second comparator outputs a high-level signal; if the analog power signal is lower than the second reference value, the second comparator outputs a low-level signal. When both the first and second comparators output high levels, the AND gate outputs a high level to the NOT gate, which inverts and outputs a low level to the data processing unit. The data processing unit receives the low-level signal and performs no action. However, when either the first or second comparator outputs a low level, the AND gate outputs a low level to the NOT gate, which inverts and outputs a high level to the data processing unit. At this time, the data processing unit outputs a control signal to control the relay to perform a contact switching action, switching the contacts from the main power supply to the backup power supply.

[0065] Food delivery robots often experience significant discrepancies between battery readings and actual battery levels due to power supply aging and failures. Inaccurate monitoring of actual battery levels can lead to unexpected interruptions in the robot's operation. This embodiment significantly improves the reliability and stability of the food delivery robot through a dual comparison mechanism. The first comparator monitors the main power supply voltage to ensure it remains within the normal range, while the second comparator checks if the battery level meets the minimum operating requirements. When both conditions are met, the system maintains normal operation; in the event of an anomaly, it promptly switches to the backup power supply, ensuring the smooth execution of delivery tasks, reducing losses caused by power failures, improving user experience, and providing strong support for the efficient operation of the restaurant.

[0066] like Figure 3 As shown, in one embodiment of this disclosure, the food delivery robot control system further includes:

[0067] Vibration monitoring equipment, pressure monitoring equipment, and shock absorbers;

[0068] Vibration monitoring equipment, pressure monitoring equipment, and shock absorbers are all connected to the control system.

[0069] In this embodiment, the pressure monitoring device includes:

[0070] Multiple pressure sensors; all pressure sensors are connected to the control system.

[0071] Multiple pressure sensors are installed at different wheels on the chassis of the food delivery robot.

[0072] In this embodiment, the vibration monitoring device includes:

[0073] Strain gauge vibration sensors and piezoelectric vibration sensors;

[0074] Both strain gauge vibration sensors and piezoelectric vibration sensors are connected to the control system;

[0075] Strain gauge vibration sensors are installed at the joints of the robotic arm, the storage compartment, and the chassis of the food delivery robot;

[0076] The piezoelectric vibration sensor is mounted on the motor housing of the food delivery robot.

[0077] In this embodiment, multiple pressure sensors need to be evenly distributed near the wheel hubs of the food delivery robot's chassis wheels. This allows for direct measurement of the pressure exerted on the wheels when they contact the ground, thereby obtaining information such as the load status of the food delivery robot and the flatness of the ground. At the same time, based on the pressure data at different locations, it can be determined whether the food delivery robot is unbalanced, and preventive measures can be taken in time to avoid the robot shaking or falling.

[0078] For example, the pressure sensor is fixed to a specific position on the chassis wheel by bolts or welding, and its signal output terminal is connected to the signal acquisition interface of the control system via a shielded cable. When the wheel is subjected to pressure, the resistance value inside the sensor changes, thereby generating an electrical signal proportional to the pressure. Based on the electrical signal fed back by the pressure sensor, the control system can determine whether the robot is overloaded and whether it has encountered obstacles or uneven ground during travel, and then take corresponding measures, such as adjusting the travel speed or route, or transmitting alarm signals to the staff.

[0079] In this embodiment, strain gauge vibration sensors are installed at the joints of the robotic arm to monitor the vibration of the robotic arm during movement in real time, ensuring the accuracy and stability of grasping and placing items. Strain gauge vibration sensors are installed at the bottom and sides of the storage compartment to detect the vibration of the storage compartment during transportation, preventing items from being damaged by excessive vibration. Sensors are installed at key support parts of the chassis to understand the overall vibration state of the chassis, providing data for the overall stability assessment of the robot.

[0080] For example, strain gauge vibration sensors are tightly bonded to the surface of a metal structure at the target location, and the resistance change caused by strain is converted into a voltage signal using a Wheatstone bridge circuit. These signals, after preprocessing such as amplification and filtering, are transmitted to the control system via cables. The control system determines whether the robot's operating status is normal based on the characteristics of the received vibration signals, such as vibration frequency and amplitude. If the vibration exceeds a preset reference range, the control system can reduce the robot's speed, adjust its posture, or activate shock absorbers to reduce the impact of vibration on the robot and the transported goods.

[0081] In this embodiment, the piezoelectric vibration sensor is installed on the motor housing near the bearing or rotor, because these parts are the key areas for the generation and transmission of motor vibration. By directly measuring the vibration of the motor housing, the operating status of the motor can be effectively monitored, such as whether there is abnormal vibration caused by imbalance, wear or other faults.

[0082] For example, a piezoelectric vibration sensor utilizes the piezoelectric effect to convert the mechanical stress generated by motor vibration into an electrical signal. The piezoelectric vibration sensor is fixed to the motor housing using a specialized clamp or adhesive. Its output signal is amplified and filtered by a conditioning circuit before being transmitted to the control system. Based on the signal from the piezoelectric vibration sensor, the control system can monitor the motor's vibration in real time. If abnormal vibration is detected, such as a sudden increase in vibration amplitude, the control system can promptly generate an alarm signal and illuminate a fault indicator light, and take corresponding protective measures, such as stopping the motor, adjusting the motor's operating parameters, or notifying maintenance personnel for repair, to prevent further deterioration of the motor fault and ensure the normal operation of the food delivery robot.

[0083] This embodiment can comprehensively and accurately acquire vibration and pressure information of the food delivery robot during operation, providing a strong guarantee for its stable and efficient operation. It also helps to improve the robot's service life and reliability, and reduce maintenance costs and failure risks.

[0084] like Figure 3 As shown, in one embodiment of this disclosure, the food delivery robot control system further includes:

[0085] Temperature sensor; the temperature sensor is installed in the storage compartment of the food delivery robot;

[0086] The temperature sensor is connected to the control system.

[0087] In this embodiment, temperature sensors can be installed at the top and bottom of the storage compartment. The top sensor can monitor the temperature of the area where hot air rises and accumulates, while the bottom sensor can detect possible temperature stratification, especially at the bottom near the cooling or heating elements. This helps to understand the temperature gradient of the entire storage space and ensure that the temperatures of the upper and lower layers are within a suitable range.

[0088] Temperature sensors can also be placed near the door. Since the door is frequently opened and closed during food delivery, outside air can easily enter. Placing a sensor here can quickly detect temperature changes caused by opening the door, so as to adjust the temperature environment of the storage compartment in a timely manner and reduce the impact of the external environment on the internal temperature.

[0089] For example, temperature sensors utilize the characteristics of thermistors and other thermistors, whose resistance changes with ambient temperature, thus generating different electrical signals. The control system collects and analyzes these electrical signals, converting them into corresponding temperature values.

[0090] This embodiment ensures that the items (especially food) in the food delivery robot's storage compartment are always kept at a suitable temperature. By monitoring the temperature in real time, the control system can take corresponding measures according to the set temperature range, such as activating or adjusting the cooling and heating devices, thereby ensuring the quality and safety of the delivered food and improving the customer's dining experience.

[0091] like Figure 3 As shown, in one embodiment of this disclosure, the food delivery robot control system further includes:

[0092] Light intensity sensor and infrared illumination device; both the light intensity sensor and infrared illumination device are connected to the control system;

[0093] Both the light intensity sensor and the infrared lighting device are installed on the food delivery robot.

[0094] In this embodiment, the control system is also configured to activate the infrared lighting device when the received light intensity data from the light intensity sensor is lower than a preset threshold. The light intensity sensor can be positioned above the robot's head (similar to the position of a human eye), enabling it to comprehensively perceive the lighting conditions of the robot's surroundings without being obstructed by its own structure. This allows for accurate measurement of ambient light intensity, providing reliable light data to the control system to determine whether the lighting device needs to be turned on.

[0095] Light intensity sensors can also be placed around the food delivery platform. This location can detect the effect of light on the food delivery area, ensuring that operators can clearly see the operation process when the robot places or retrieves food in low light conditions, thus avoiding operational errors caused by insufficient light.

[0096] Infrared lighting equipment can be placed on both sides in front of the robot, shining at a certain angle in the direction the robot is moving. This can illuminate the path in front of the robot and the surrounding area, ensuring that the robot can drive and deliver food safely in low light environments, while avoiding direct light shining into people's eyes and causing discomfort.

[0097] For example, a light intensity sensor can use a photosensitive element, such as a photoresistor or photodiode, whose electrical characteristics change with the intensity of light. When light shines on the sensor, the current or voltage signal generated by the photosensitive element changes accordingly. The control system collects and analyzes these signals, converts them into actual light intensity values, and compares them with a preset threshold. When the light intensity is below the preset threshold, the control system issues a command to activate the infrared lighting device. The infrared lighting device uses infrared LEDs to emit infrared light invisible to the human eye, illuminating the surrounding environment.

[0098] This embodiment enables the food delivery robot to operate normally and perform food delivery tasks even in low-light environments, improving the robot's work flexibility and adaptability, ensuring the continuity and stability of food delivery services, and reducing operational obstacles and potential safety risks caused by insufficient light.

[0099] like Figure 3 As shown, in one embodiment of this disclosure, the food delivery robot control system further includes:

[0100] Wireless communication equipment;

[0101] Wireless communication devices are connected to the control system;

[0102] The control system connects to an external mobile terminal via wireless communication equipment.

[0103] In this embodiment, the wireless communication device may include a Wi-Fi module or a Bluetooth module. A Wi-Fi module enables the food delivery robot to connect to the restaurant's wireless network, suitable for transmitting large amounts of data, such as robot status information and food delivery task information. A Bluetooth module is suitable for short-range device connections and can be used for simple control command transmission and device pairing.

[0104] For example, the Wi-Fi module receives and transmits radio signals compliant with the Wi-Fi protocol via a built-in antenna. After pairing with the restaurant's wireless router, the control system's data is modulated into Wi-Fi signals and transmitted, while simultaneously receiving Wi-Fi signals from external mobile terminals (such as mobile phones, tablets, etc.) and demodulating them into data.

[0105] This embodiment enables information interaction between the food delivery robot and an external mobile terminal. Restaurant staff can remotely monitor the robot's operating status, such as battery level, location, and delivery progress, through the mobile terminal. They can also send control commands to the robot, such as starting a delivery task, returning to charging, or changing the delivery route, thereby improving the intelligent management level and work efficiency of the food delivery robot.

[0106] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this disclosure.
