Description

Technical Field

[0001] The present invention relates to the field of Internet of Things control technology, and in particular to a control device applied to industrial Internet of Things. Background Art

[0002] PLC controller, or programmable logic controller, is a digital computing and operating electronic system designed for use in industrial environments. PLC can receive input signals from sensors and control output devices based on these signals and preset logic rules. This logic control function enables PLC to replace traditional relay control cabinets and achieve more complex and flexible control logic and sequential control. In many industrial processes, operations need to be performed in a specific order. PLC can implement complex sequential control through programming to ensure that each step is performed at the right time. PLC can communicate with other PLCs, sensors, actuators, and host computers (such as HMI, SCADA systems) to achieve real-time data exchange and remote monitoring. This communication capability makes PLC a key node in the Industrial Internet of Things (IIoT) and smart manufacturing networks.

[0003] Some PLC controllers have added IoT functions, which increase internal energy consumption and generate more heat. Therefore, it is particularly important to cool down the IoT PLC controller. At present, some PLC controllers are equipped with fans for cooling to keep the main circuit board below 55°C. In addition, temperature sensors are set on the circuit board to monitor temperature changes in real time and transmit them to the industrial system. Some PLC controllers are usually set inside the staff's operating table, close to the staff. PLC controllers are generally equipped with spare ones. After a failure occurs, they can switch to the spare PLC controller, but it takes time. PLC controllers sometimes have high-temperature circuit board failures due to fan failures. At this time, the staff finds abnormal temperature alarms on the system monitoring of the operating table, and can also operate and switch to the spare PLC in time. After the switch is completed, the PLC with temperature failure is turned off; however, there are also occasions where the temperature sensor and the fan fail at the same time. The staff often cannot get the alarm in time, and the PLC shuts down or burns due to long-term operation above 70°C, causing property losses. It will also affect normal work because there is no time to switch to the spare PLC controller. Summary of the invention

[0004] The purpose of the present invention is to provide a control device for industrial Internet of Things, which can temporarily cool down the circuit board itself and issue an audible alarm when the temperature sensor and fan of the controller itself fail at the same time, reminding the staff that the controller itself has failed, thereby buying precious time for the staff to switch to a backup controller and shut down the failed controller.

[0047] The cooling mechanism 13 includes a long cylinder 131, a piston 132 and a movable rod 133. The long cylinder 131 is in two groups and is bolted to the upper and lower sides of the surface of the rotating cover 11. The piston 132 is slidably connected to the inner wall of the long cylinder 131. One end of the movable rod 133 is bolted to the piston 132. The end of the movable rod 133 away from the piston 132 is bolted to a movable plate 134. A transverse groove 139 is also provided on the surface of the rotating cover 11.

The surface of the long cylinder 131 is also provided with a liquid inlet 136 A first sealing cover 137 is provided on the surface of the liquid inlet 136, and the first sealing cover 137 and the liquid inlet 136 are fixed to each other by threads. A through hole 138 is also penetrated and opened on the surface of the rotating cover 11, and the first sealing cover 137 is located on the inner side of the through hole 138. The liquid inlet 136 is convenient for the staff to add coolant to the inside of the long cylinder 131. At the same time, the first sealing cover 137 can seal the liquid inlet 136. A first connecting pipe 1310 is provided on one side of the long cylinder 131. The first connecting pipes 1310 on the upper and lower sides are connected to each other through a three-way interface. The cooling mechanism 13 also includes a long hose 1312 and a first box body 1313. The long hose 131 One end of the long hose 1312 is connected to the first connecting pipe 1310 through a three-way interface, and a bracket 16 is bolted to the inner wall of the shell 1 for auxiliary support of the long hose 1312, lifting the long hose 1312 to prevent it from sagging in a relaxed state and contacting other internal components. The other end of the long hose 1312 is connected to the first box body 1313, and the first box body 1313 is connected to the side away from the long hose 1312. A second connecting pipe 1314 is installed on the surface of the second connecting pipe 1314. A second box body 1316 is bolted to the upper back of the copper plate 8, and one end of the second connecting pipe 1314 passes through the second box body 1316. Inside, a threaded cap 1317 is also provided at one end of the second connecting pipe 1314. The threaded cap 1317 is made of polyvinyl chloride and has a thermal deformation temperature of about 70°C-80°C. The inner wall of the second connecting pipe 1314 at one end inside the second box body 1316 is provided with threads for fixing the threaded cap 1317 there. A plurality of copper tubes 1318 are connected to the bottom of the second box body 1316, and the surface of the copper tubes 1318 fits with the back of the copper plate 8. A fixed plate 1311 is also bolted to the surface of the rotating cover 11. A second spring 135 is installed on the surface of the fixed plate 1311, and the other end of the second spring 135 is fixed to the movable plate 134.

[0048] The positioning mechanism 14 includes a pin rod 141, a positioning hole 142 and a pin hole 143. One end of the pin rod 141 is bolted to the movable plate 134. The positioning hole 142 penetrates the surface of the fixed plate 1311, and the pin hole 143 is formed on the surface of the housing 1. Before working, the rotating cover 11 is first closed. The inner diameter of the positioning hole 142 is the same as the inner diameter of the pin hole 143. When the rotating cover 11 is closed, the fixed plate 1311 contacts the first spring 12 and makes the first spring 12 in a compressed state. At the same time, the positioning hole 142 and the pin hole 143 are aligned with each other. The screwdriver is inserted into the transverse groove 139 to push the movable plate 134 to move, and the movable plate 134 drives the movable rod 133, the piston 132 and the pin rod 141 to move together in the direction close to the fixed plate 1311, so that the second spring 135 is in a compressed state, and then the pin rod 141 passes through the positioning hole 142 and the pin hole 143 in sequence. At the same time, another set of screwdrivers enters the through hole 138, rotates the first sealing cover 137, removes the first sealing cover 137 from the surface of the liquid inlet 136, and then injects liquid into the interior of the long cylinder 131 through the liquid inlet 136. A sufficient amount of coolant is added, and the coolant can be cooling oil. After the coolant passes through the first connecting pipe 1310, the long hose 1312, the first box body 1313 and the second connecting pipe 1314, the interior of the long cylinder 131, the first connecting pipe 1310, the long hose 1312, the first box body 1313 and the second connecting pipe 1314 are all filled with the coolant, and then the first sealing cover 137 is closed, and the movable plate 134 is loosened. Due to the blocking effect of the internal coolant, the piston 132, the movable rod 133 and the movable plate 134 will not be reset under the reaction force of the second spring 135. At the same time, the pin rod 141 will not separate from the positioning hole 142 and the pin hole 143, fixing the rotating cover 11 on the surface of the shell 1, and the fixing plate 1311 is attached to the surface of the first spring 12 and puts it in a compressed state. The long cylinder 131 adopts a heat-insulating design and uses heat-insulating plastic. The first connecting pipe 1310 and the first box body 1313 both use heat-insulating plastic. The long hose 1312 uses a heat-insulating hose material. In this way, the heat generated by the PLC controller during operation will not affect the coolant inside the long cylinder 131, the first connecting pipe 1310 and the long hose 1312.

[0049] When the control device is working, the heat generated by the circuit board body 2 is transferred to the surface of the copper plate 8 through the silicone grease layer 7. The copper sheet 9 arranged on the back of the copper plate 8 serves as an extension of the copper plate 8 to increase the contact area with the flowing air. The fan body 10 is turned on and blows air to the back of the copper plate 8. The flowing air takes away the heat on the surfaces of the copper plate 8 and the copper sheet 9, thereby cooling the circuit board body 2 so that the temperature of the circuit board body 2 does not exceed 55°C. In addition, the temperature sensor body 6 monitors the temperature of the circuit board body 2 and transmits it to the operating system of the industrial workshop. The staff can see the temperature of the circuit board body 2 of the PLC control device in real time on the operating table. If only the fan body 10 fails and the temperature of the circuit board body 2 rises, the staff can The abnormal temperature monitored by the temperature sensor body 6 can be seen, and the standby PLC controller can be manually operated and switched in time, and then the faulty PLC controller can be shut down, or the industrial Internet of Things system can automatically switch. However, after the fan body 10 and the temperature sensor body 6 fail, the system cannot receive the temperature information from the circuit board body 2, and thus cannot realize early warning and automatic switching. The staff temporarily knows that the PLC controller has a temperature rise failure. At this time, the temperature of the circuit board body 2 continues to rise. The second connecting pipe 1314 and the second box body 1316 are both made of copper. The heat generated by the circuit board body 2 can also be transferred to the second connecting pipe 1314 and the second box body 1316. The second connecting pipe 1314 is close to the check valve 13 The coolant at the front end of 15 also rises with the temperature, but is hindered by the check valve 1315, and the heated coolant will not return. When it is close to 70°C, the threaded cap 1317 gradually deforms and melts (the threaded cap 1317 is always heated to a temperature close to 70°C when the circuit board body 2 is working. When the temperature of the circuit board body 2 rises due to an abnormality, the temperature of the threaded cap 1317 is also likely to rise). In addition, the second spring 135 applies pressure to the movable plate 134, the movable rod 133 and the piston 132 in a direction away from the fixed plate 1311, and applies a force to the coolant inside the long cylinder 131, so that the deformation speed of the threaded cap 1317 is accelerated. After the circuit board body 2 is at about 70°C for a short time, it is about to burn out (the circuit board body 2 is about to burn out). When the temperature of the capacitor on the capacitor is above 70°C, there is a risk of burning). After the threaded cap 1317 is deformed, the thread may fall off or partially crack, and it will be washed open by the liquid in the second connecting pipe 1314. At this time, the coolant in the long tube 131 is pushed into the first connecting pipe 1310 under the action of the second spring 135, the movable plate 134, the movable rod 133 and the piston 132, so that the coolant in the first connecting pipe 1310, the long hose 1312, the first box body 1313 and the second connecting pipe 1314 flows to the inside of the second box body 1316 and flows into the inside of the copper tube 1318. The low-temperature coolant temporarily cools the copper plate 8 and the circuit board body 2, winning time for the staff to switch the operating system to the standby PLC controller.At the same time, when the second spring 135 pushes the movable plate 134 to move, the pin rod 141 is driven to disengage from the pin hole 143 and the positioning hole 142 in sequence, releasing the positioning of the rotating cover 11. The first spring 12 applies a reaction force to the fixed plate 1311, which pops open the fixed plate 1311 and also drives the rotating cover 11 to rotate, so that the inside of the housing 1 is in an open state, so that the circuit board body 2 can contact with more external air in a short time, and better assist in cooling, and prevent heat from accumulating inside the housing 1.

[0050] A storage box 1319 is bolted to the lower part of the shell 1, and the other end of the copper tube 1318 is connected to the storage box 1319. The coolant flowing through the copper tube 1318 enters the storage box 1319 for storage to prevent it from flowing to other components inside the controller. One side of the storage box 1319 is also connected to a liquid outlet 1320, and a second sealing cover 1321 is provided on the surface of the liquid outlet 1320. The second sealing cover 1321 is fixed to the liquid outlet 1320 through threads and can be rotated down or tightened.

[0051] The sound mechanism 15 includes an impeller 151, a rotating column 152 and a rotating column 153. The rotating column 152 is rotatably connected to the inner wall of the first box body 1313. The impeller 151 is bolted to the surface of the rotating column 152 and is located inside the first box body 1313. A cover body 154 is also bolted to one side of the first box body 1313. The rotating column 153 is rotatably connected to the inner wall of the cover body 154. The rotating column 153 is connected to the rotating column 152 through a gear transmission. The cover body 15 The side close to the first box body 1313 is open-type and does not contact the first box body 1313. The side of the cover body 154 is also connected with an air supply pipe 155. The end of the air supply pipe 155 away from the cover body 154 is connected with a steel whistle 156. The inlet of the steel whistle 156 is connected with the air supply pipe 155. The air outlet of the steel whistle 156 is aligned with the bottom of the copper plate 8. When the cooling mechanism 13 is working, the cooling liquid is discharged to protect the circuit board body 2. During temporary cooling, when the coolant passes through the first box body 1313, it can push the impeller 151 to rotate, and the impeller 151 drives the rotating column 152 to rotate, and then the rotating column 152 drives the rotating column 153 to rotate through the gear, and the rotating column 152 drives the rotating column 153 to rotate in the manner of a large gear driving a small gear. The surface of the rotating column 153 is fixed with a fan blade 157, which drives the fan blade 157 to rotate, and allows the surrounding air to enter the interior of the cover body 154, and then enter the interior of the steel whistle 156 through the air supply pipe 155, thereby blowing to the steel whistle 156, attracting the attention of the staff on the operating table, so that the staff can immediately know that the PLC control device has a temperature fault, and perform temporary cooling work in combination with the cooling mechanism 13. Before the PLC with a temperature fault is about to burn out, the staff has time to switch to the standby PLC through the system, and can shut down the PLC with a temperature fault in time to reduce losses.

[0052] Moreover, when repairing a PLC control device with a temperature fault, the rotating cover 11 is in an open state, which also brings convenience to the repair; during the repair process of the faulty PLC control device, the circuit board body 2 and the copper plate 8 can be disassembled, and the second box body 1316 can be disassembled, and the connection with the second connecting pipe 1314 can be released, and a new threaded cap 1317 can be replaced on the second connecting pipe 1314. At the same time, the second sealing cover 1321 is opened, and the coolant inside the storage box 1319 is emptied through the liquid outlet 1320.
