Description

Technical Field

[0001] This utility model relates to the field of snow melting technology, and in particular to an indoor unmanned robot container intelligent snow melting system. Background Technology

[0002] In cold regions, snow and ice accumulation in front of container doors has always been a significant problem hindering container operation. Currently, most snow removal in front of container doors relies on manual sweeping or the application of de-icing agents. However, manual sweeping is inefficient and poses safety hazards in severe weather conditions; while de-icing agents, whose main components are chloride salts, can lower the melting temperature of snow and ice, they can corrode the metal plates in front of the container doors, chassis tires, etc. Furthermore, salts dissolved in water are conductive, easily causing rust on the chassis of unmanned robots, affecting the equipment's lifespan and safety. In addition, for indoor unmanned robots, snow or ice accumulation in front of container doors may cause the robot's chassis to slip after exiting the container, leading to scraping against the container body and unnecessary maintenance work. Utility Model Content

[0005] The industrial computer is connected to the control cabinet and is used to receive the ambient temperature and humidity signals transmitted by the control cabinet. Based on the ambient temperature and humidity signals, it determines whether the snow melting operation needs to be started. When the snow melting operation is started, it sends a heating control signal to the control cabinet.

[0006] The control cabinet is used to receive ambient temperature and humidity signals from temperature and humidity sensors and upload these signals to the industrial control computer. When it receives a heating control signal from the industrial control computer, it starts the electric heating element via the isolation transformer.

[0011] Optionally, each channel's industrial control terminal includes multiple sets of isolation transformers and electric heating elements, with each set of isolation transformers connected to one electric heating element, to enable independent snow melting operations in multiple areas.

[0012] Optionally, the system also includes a linear pressure gauge connected to the output of the main power switch. The linear pressure gauge is used to detect in real time whether the incoming voltage, current and frequency after passing through the main power switch are normal, and to send a fault alarm signal to the control cabinet when an abnormality is detected, so that the control cabinet can handle the fault according to the signal.

[0013] Optionally, the system further includes a short-circuit protection device for immediately cutting off power when a short circuit occurs in the circuit.

[0014] Optionally, the system also includes a leakage current protector for real-time detection of whether the circuit is leaking current and for immediately cutting off the power supply when leakage occurs.

[0015] Optionally, the system also includes a backup battery installed inside the industrial control terminal to maintain operation in the event of a sudden power outage. If power is not restored within 10 minutes, the heating plate will stop working.

[0016] Optionally, the system also includes a remote monitoring and management module that supports three modes: local control, container control, and remote control. It is used to display the working status, voltage, current, and other information of the heating element in real time and to provide fault alarms. At the same time, it records operator information and sets corresponding operation permissions according to different management levels.

[0017] Optionally, the remote monitoring and management module supports three modes: local control, container control, and remote control, specifically including:

[0018] Local control mode includes operating the snow melting system directly through a local control panel installed on the control cabinet, including starting and stopping the heating operation, as well as manually setting the heating parameters;

[0019] The container control mode includes controlling the snow melting system via a control terminal installed inside the container; this control terminal communicates with the control cabinet, allowing operators to remotely operate the snow melting system from inside the container, including starting and stopping the heating operation, as well as adjusting the heating parameters;

[0020] The remote control mode includes remote monitoring and management of the snow melting system via network connection; the remote control terminal communicates with the industrial control computer to remotely operate the snow melting system, including starting and stopping the heating operation, as well as adjusting the heating parameters.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] Currently, the company uses shipping containers to store indoor unmanned robot equipment, providing power and a constant temperature environment for the devices. However, if snow or ice accumulates on the outside of the container during the robot's descent after exiting the container, the robot's chassis may slip, causing it to scrape against the container and resulting in avoidable maintenance work.

[0032] The equipment in this application is powered by a dedicated circuit and is suitable for both centralized and distributed snow melting, depending on the specific usage environment. The snow melting equipment supports three modes: local control, container control, and remote control. The system has functions such as diagnostics, alarms, remote monitoring, and management.

[0033] For details, please refer to Figure 1 The diagram illustrates a block diagram of an indoor unmanned robot container intelligent snow melting system provided in an embodiment of this application. The system includes multiple channels of industrial control terminals, wherein each channel's industrial control terminal specifically includes:

[0034] Industrial computer 1 is connected to control cabinet 2 and is used to receive the ambient temperature and humidity signal transmitted by control cabinet 2. It determines whether the snow melting operation needs to be started based on the ambient temperature and humidity signal. When the snow melting operation is started, it sends a heating control signal to control cabinet 2.

[0035] Control cabinet 2 is used to receive ambient temperature and humidity signals from temperature sensor 5 and humidity sensor, and upload the ambient temperature and humidity signals to industrial computer 1. When it receives the heating control signal sent by industrial computer 1, it starts the electric heating element 6 through isolation transformer 3.

[0036] Isolation transformer 3 is connected to control cabinet 2 and electric heating element 6 respectively. It is used to electrically isolate control cabinet 2 from the corresponding electric heating element 6, so as to ensure the safe operation of the system and stabilize the output voltage.

[0037] Temperature sensor 5 is connected to control cabinet 2 and is used to detect the ambient temperature outside the container door in real time and transmit the temperature signal to control cabinet 2.

[0038] A humidity sensor, connected to control cabinet 2, is used to detect the ambient humidity outside the container door in real time and transmit the humidity signal to control cabinet 2.

[0039] An electric heating element 6 is connected to an isolation transformer 3. A pressure sensor 4 is installed in the electric heating element 6 to heat and melt snow based on the output voltage of the isolation transformer 3. The power supply is cut off to stop heating when the pressure signal in the pressure sensor 4 exceeds a threshold. Each channel's industrial control terminal includes multiple sets of isolation transformers 3 and electric heating elements 6. Each set of isolation transformers 3 is connected to one electric heating element 6, enabling independent snow melting operations in multiple areas.

[0040] In an optional embodiment of this application, an unmanned robot container intelligent snow melting system includes hardware such as an industrial control computer 1, a PLC, a control cabinet 2, an isolation transformer 3, a temperature and humidity sensor, a pressure detection switch, various types of fuses, short circuit protection, a pressure gauge, an ammeter, a contactor, a circuit breaker, and a leakage current protector; the terminal power-consuming equipment includes an electric heating element 6.

[0041] The control core is an S7-1200. The input of this controller is responsible for collecting the status of various temperature sensors, the soft emergency stop signal provided by remote control, and the necessary buttons for manual operation. The output is responsible for controlling the engagement and disengagement of various contactors. The controller needs to select an analog input / output module, leaving the analog channel empty because of its poor stability. The analog input is responsible for reading the temperature and humidity sensors to determine the icing situation outside the container door, and controlling whether to perform centralized or localized snow melting.

[0042] The linear pressure gauge is connected to the lower terminal of the main power circuit breaker. First, ensure that the voltage, current and frequency values ​​of the incoming power are normal. If there is an abnormality, a fault alarm will be sent to the host computer.

[0043] When the PLC's digital input is connected to the switch pressure sensor 4, if the pressure exceeds the set value, the switch will send feedback to the corresponding area and cut off the power supply to that area.

[0044] The PLC's digital outputs connect to various contactors and relays, allowing for the control of power supply to different areas.

[0045] The temperature sensor 5 value will also be uploaded to the host computer and compared with the weather forecast for the day. If the deviation is large and it is obviously an abnormal value, it will be displayed in the measurement data section and a fault alarm will be triggered.

[0046] The operating status, operating voltage, and current of each heating circuit are displayed on the host computer in real time, and the values ​​are also calculated. If a certain part is significantly higher or lower than the average value, the host computer will display an alarm for that part.

[0047] Use pressure gauges and ammeters to perform real-time testing on circuit breakers, contactors, and residual current devices, and save the results for at least 15 days.

[0048] The heating plate is customized into a 10cm*10cm square block with pressure resistance requirements. Each heating block is equipped with a pressure sensor 4, and the PLC collects the pressure in real time. If the pressure is too high, the power supply to the heating plate is cut off to prevent the heating plate from being damaged by the force during heating.

[0049] Whether controlled locally or remotely, operator information is recorded; separate account passwords are set for personnel at different management levels, and different shutdown levels result in significantly different operational permissions on the remote control platform; the remote monitoring and management module supports three modes: local control, container control, and remote control, specifically including:

[0050] Local control mode, including direct operation of the snow melting system via the local control panel installed on control cabinet 2, including starting and stopping heating operations, as well as manually setting heating parameters;

[0051] The container control mode includes controlling the snow melting system via a control terminal installed inside the container; this control terminal communicates with control cabinet 2, allowing operators to remotely operate the snow melting system from inside the container, including starting and stopping the heating operation, as well as adjusting the heating parameters;

[0052] The remote control mode includes remote monitoring and management of the snow melting system via network connection; wherein the remote control terminal communicates with the industrial control computer 1 to remotely operate the snow melting system, including starting and stopping the heating operation, as well as adjusting the heating parameters.

[0053] The control cabinet 2 internally tracks the heating time, number of heating cycles, and total power consumption for each heating plate circuit, with the heating time accuracy displayed down to the minute.

[0054] In automatic heating mode, the heating plates will be turned on one by one. If the power is suddenly cut off during operation, the container has a backup battery that can keep the power supply running for about 10 minutes. If the power is restored within 10 minutes, the automatic program will not be affected. If it exceeds 10 minutes, the heating plates cannot be guaranteed to work normally.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
