[0002] With the progress of technology, robot technology has developed rapidly. Industrial robots are usually provided with a robot control cabinet to control the operation of the robot. A variety of electronic devices are arranged inside the control cabinet. If the temperature inside the robot control cabinet is too high, it is easy to damage the electronic devices and even cause a fire. Summary of the Invention

[0003] The purpose of the present disclosure is to provide a temperature monitoring system for a robot control cabinet and a robot control cabinet, which can meet the heat dissipation requirements of the robot control cabinet while reducing energy consumption and improving the service life.

[0004] To achieve the above purpose, the present disclosure provides a temperature monitoring system for a robot control cabinet, and the temperature monitoring system includes:

[0005] An infrared temperature measuring device, which is arranged in the control cabinet and is used for collecting the temperature inside the control cabinet;

[0006] A controller, which is used for receiving the temperature collected by the infrared temperature measuring device and controlling the operation of the cooling device;

[0007] The cooling device, which is arranged in the control cabinet and is connected to the controller, and is used for dissipating heat from the control cabinet;

[0008] Wherein, a switching device is arranged in the cooling device. When the temperature inside the control cabinet is greater than a first temperature threshold, the controller controls the switching device to cut off the power supply of the cooling device. When the temperature inside the control cabinet is less than a second temperature threshold, the controller controls the switching device to turn on the power supply of the cooling device, and the first temperature threshold is greater than the second temperature threshold.

[0009] Optionally, the switching device includes a relay.

[0010] Optionally, the temperature monitoring system further includes an alarm device, which is connected to the infrared temperature measuring device and is used for outputting an alarm message when the temperature inside the control cabinet is greater than a third temperature threshold.

[0011] Optionally, the alarm device includes a buzzer and / or an indicator light.

[0012] Optionally, the temperature monitoring system further includes an output device, which is connected to the infrared temperature measuring device and is used for outputting the temperature collected by the infrared temperature measuring device.

[0015] Optionally, the cooling device includes a fan and / or an air conditioner.

[0016] Optionally, the temperature monitoring system further includes a DC / DC conversion circuit for converting an external DC power supply voltage into a low-voltage DC voltage.

[0018] Through the above technical solution, the temperature monitoring system of the robot control cabinet includes an infrared temperature measuring device, a controller, and a cooling device. The cooling device is arranged in the control cabinet for collecting the temperature inside the control cabinet. The controller is configured to receive the temperature collected by the infrared temperature measuring device and control the operation of the cooling device. The cooling device is arranged in the control cabinet and connected to the controller for dissipating heat from the control cabinet. When the temperature inside the control cabinet is greater than the first temperature threshold, the controller controls the switching device to cut off the power supply of the cooling device. When the temperature inside the control cabinet is less than the second temperature threshold, the controller controls the switching device to power on the cooling device. In this way, when the temperature inside the robot control cabinet is relatively high, the operation of the cooling device is controlled. When the temperature inside the robot control cabinet is relatively low, the operation of the cooling device is not controlled, which not only meets the heat dissipation requirements of the robot control cabinet but also reduces energy consumption and improves the service life.

[0019] Other features and advantages of the present disclosure will be described in detail in the subsequent specific implementation section. Description of the Drawings

[0020] The drawings are used to provide a further understanding of the present disclosure and constitute a part of the specification. They are used together with the following specific implementation to explain the present disclosure, but do not limit the present disclosure. In the drawings:

[0021] Figure 1 is a schematic diagram of a temperature monitoring system shown according to an exemplary embodiment.

[0022] Figure 2 is a schematic diagram of a temperature monitoring system shown according to another exemplary embodiment.

[0023] Description of the Reference Numerals

[0024] 1 Infrared temperature measuring device 2 Controller 3 Cooling device

[0025] 4 Switch device 5 Alarm device 6 Output device

[0026] 7 Wireless communication device 8 DC / DC conversion circuit 100 Temperature monitoring system Detailed implementation manner

[0027] Figure 1 is a schematic diagram of a temperature monitoring system shown according to an exemplary embodiment. As Figure 1 shown, the temperature monitoring system 100 includes an infrared temperature measuring device 1, a controller 2, and a cooling device 3.

[0028] The infrared temperature measuring device 1 is arranged in the control cabinet and is used for collecting the temperature inside the control cabinet.

[0029] The controller 2 is used for receiving the temperature collected by the infrared temperature measuring device 1 and controlling the operation of the cooling device 3.

[0030] The cooling device 3 is arranged in the control cabinet and is connected to the controller 2 and is used for dissipating heat from the control cabinet.

[0031] Wherein, a switch device 4 is arranged in the cooling device 3. When the temperature inside the control cabinet is greater than the first temperature threshold, the controller 2 controls the switch device 4 to cut off the power supply of the cooling device 3. When the temperature inside the control cabinet is less than the second temperature threshold, the controller 2 controls the switch device 4 to power on the cooling device 3. The first temperature threshold is greater than the second temperature threshold.

[0032] The infrared temperature measuring device 1 can be, for example, an infrared temperature measuring probe. The first temperature threshold can be preset by the designer and can be, for example, 35°C. When the temperature inside the control cabinet is greater than the first temperature threshold, the temperature inside the control cabinet is relatively high, and it is necessary for the cooling device 3 to operate to meet the heat dissipation requirement. The switch device 4 can be controlled to be turned off so that the cooling device 3 is powered on. The first temperature threshold can be preset by the designer and can be, for example, 32°C. When the temperature inside the control cabinet is less than the second temperature threshold, the temperature inside the control cabinet is relatively low, and it is not necessary for the cooling device 3 to operate. The heat dissipation requirement can be met only by the heat dissipation capacity of each electronic device inside the control cabinet. The switch device 4 can be controlled to be turned on so that the cooling device 3 is cut off the power supply.

[0033] Through the above technical solution, the temperature monitoring system of the robot control cabinet includes an infrared temperature measuring device, a controller, and a cooling device. The cooling device is arranged in the control cabinet and is used to collect the temperature inside the control cabinet. The controller is used to receive the temperature collected by the infrared temperature measuring device and control the operation of the cooling device. The cooling device is arranged in the control cabinet and is connected to the controller for dissipating heat from the control cabinet. When the temperature inside the control cabinet is greater than the first temperature threshold, the controller controls the switching device to cut off the power supply of the cooling device. When the temperature inside the control cabinet is less than the second temperature threshold, the controller controls the switching device to power on the cooling device. In this way, when the temperature inside the robot control cabinet is relatively high, the operation of the cooling device is controlled. When the temperature inside the robot control cabinet is relatively low, the operation of the cooling device is controlled not to run, meeting the heat dissipation requirements of the robot control cabinet while reducing energy consumption and extending the service life.

[0034] In another embodiment, the switching device 4 includes a relay.

[0035] A relay is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity reaches the specified requirement. It is an "automatic switch" that controls the operation of a large current with a small current.

[0036] In this embodiment, by using the relay switching device, the opening or closing of the switching device can be remotely and automatically controlled.

[0037] Figure 2 It is a schematic diagram of a temperature monitoring system shown according to another exemplary embodiment. As Figure 2 shown, the temperature monitoring system 100 further includes an alarm device 5, which is connected to the infrared temperature measuring device and is used to output an alarm message when the temperature inside the control cabinet is greater than the third temperature threshold.

[0038] The third temperature threshold can be preset by the designer. For example, it can be 50 °C. When the temperature inside the control cabinet is greater than the third temperature threshold, the cooling device 3 may malfunction, and an alarm message needs to be output in a timely manner. When multiple thresholds are set, different types of alarm messages can be corresponding sent. For example, it can be set that when the temperature is higher than 50 °C, the first alarm message is controlled to be sent, and it can be considered that the device temperature has exceeded the normal range at this time; when the temperature is higher than 60 °C, the second alarm message is controlled to be sent, and it can be considered that the temperature is relatively high at this time; when the temperature is higher than 70 °C, the first alarm message and the second alarm message are controlled to be sent, and it can be considered that the device temperature is extremely high at this time, and relevant processing by technicians is required immediately.

[0039] In this embodiment, technicians can accurately and timely obtain the alarm message, which is convenient for taking corresponding processing measures in a timely manner according to the type of the alarm message, improving the processing efficiency.

[0040] In yet another embodiment, the alarm device 5 includes a buzzer and / or an indicator light.

[0041] The buzzer achieves an alarm effect by emitting sound, and the indicator light achieves an alarm effect by flashing. The alarm message can be output through the buzzer, or through the indicator light, or simultaneously through the buzzer and the indicator light.

[0042] In this embodiment, both the buzzer and the indicator light can reliably output the alarm message.

[0043] In yet another embodiment, the temperature monitoring system 100 further includes an output device 6, connected to the infrared temperature measuring device 1, for outputting the temperature collected by the infrared temperature measuring device 1.

[0044] In this embodiment, the output device can output the temperature collected by the infrared temperature measuring device 1 in real time.

[0045] In yet another embodiment, the output device 6 includes a display screen.

[0046] In this embodiment, the display screen can display the temperature collected by the infrared temperature measuring device 1 in the form of numbers or graphs, which is highly intuitive and convenient for the staff to view.

[0047] In yet another embodiment, the temperature monitoring system 100 further includes a wireless communication device 7, connected to the infrared temperature measuring device 1, for sending the temperature collected by the infrared temperature measuring device 1 to the server. The wireless communication device 7 can be, for example, a WiFi device or a 4G device. The wireless communication device 7 can send the temperature collected by the infrared temperature measuring device 1 to the server in real time. The server can store and generate a temperature curve graph according to the date, and send it to the user's mobile terminal (such as a mobile phone). The user can view the temperature situation inside the control cabinet in real time, and can also view the temperature curve graphs of multiple control cabinets for historical dates. By analyzing the real-time temperature data and historical temperature curves, combined with the seasonal ambient temperature, equipment working load, and year-on-year and month-on-month comparisons between equipment rooms, potential equipment hazards can be predicted, providing a basis for preventing faults from occurring.

[0048] In this embodiment, the temperature collected by the infrared temperature measuring device is uploaded to the server through the wireless communication device, which is convenient for the user to view the temperature situation inside the control cabinet in real time.

[0049] In yet another embodiment, the cooling device 3 includes a fan and / or an air conditioner.

[0050] Generally, the corresponding cooling device 3 can be selected according to different heat dissipation requirements. For example, when the device temperature is higher than 50°C, it can be considered that heat dissipation needs to start at this time, and the fan is controlled to start for heat dissipation; when the device temperature is higher than 60°C, it can be considered that the temperature is relatively high at this time, and turning on the fan can no longer meet the heat dissipation effect, so the fan is controlled to turn off, and the air conditioner is controlled to start for heat dissipation; when the temperature is higher than 70°C, it can be considered that the temperature is extremely high at this time, and both the air conditioner and the fan need to be turned on for heat dissipation, so the air conditioner and the fan are controlled to turn on.

[0051] In this embodiment, heat dissipation is carried out by using an air conditioner and a fan, which has high reliability and good heat dissipation effect. Moreover, according to different heat dissipation requirements, the corresponding heat dissipation equipment is selected, which not only ensures that the heat dissipation requirements are met, but also saves electric energy.

[0052] In another embodiment, the temperature monitoring system 100 further includes a DC / DC conversion circuit 8 for converting the external DC power supply voltage into a low-voltage DC voltage.

[0053] The DC / DC conversion circuit 8 can convert the DC voltage (such as 24V) of the robot control cabinet into a low-voltage DC voltage (such as 5V) and then supply power to the temperature monitoring system 100.

[0054] In this embodiment, by setting the DC / DC conversion circuit, the temperature monitoring system can be reliably powered.

[0055] The present disclosure also provides a robot control cabinet including the above-mentioned temperature monitoring system.
