Description

Technical Field

[0001] The present invention belongs to the field of industrial control protocols, and more specifically, relates to a security identification method and device based on industrial control protocols. Background Art

[0002] Industrial control protocols refer to the various protocol instructions used in industrial automation control. Through the combination of electronic, electrical, mechanical and protocol instructions, automated production control can be achieved. They are widely used in today's intelligent machinery manufacturing to reduce production costs and improve production accuracy.

[0003] When using industrial control protocols, it is usually necessary to consider their security to prevent the execution unit from identifying and executing erroneous instructions when the industrial control protocol is invaded. In order to avoid losses caused by equipment invasion, industrial control protocols in the prior art usually use account identification to perform security authentication. This method is too simple. Once the intruder steals the account authority, the entire protocol control chain can be modified, resulting in excessive losses to the production line controlled by the protocol after the invasion.

[0004] To this end, we propose a security identification method and device based on industrial control protocol to solve some problems existing in the above-mentioned prior art. Summary of the invention

By installing the cooling unit on the machine body and automatically adjusting it according to the actual stability in the machine body, the operating efficiency of each unit in the machine body can be improved, and energy consumption can be saved to a certain extent.

[0031] Step 5: When multiple checking units receive abnormal instructions from the main control unit, the backup control unit directly determines it as the highest level of abnormality and performs an emergency power-off.

[0032] The beneficial effects of the present invention are that, compared with the prior art, the advantages of the present invention are:

[0033] (1) This solution can identify the instructions issued by the main control unit by installing a checking unit between each execution unit and the main control unit, thereby avoiding losses caused by erroneous operation of the execution unit due to erroneous instructions on the main control unit. By electrically connecting the backup control unit with the checking unit, when the checking unit identifies that the instruction of the main control unit is erroneous, it can urgently call the instructions on the backup control unit to continue controlling the operation of the execution unit, thereby avoiding shutdown of the execution unit.

[0034] (2) By electrically connecting an alarm unit to the backup control unit, an alarm can be triggered when the backup control unit is started, so as to remind the staff to deal with the abnormality in time. By cutting off the power, the entire industrial control protocol is controlled to perform emergency stop processing, which can effectively reduce the losses caused by the equipment to which the protocol is applied during production.

[0035] (3) By connecting the main heat dissipation pipe to the bottom of the machine body and installing a pump inside the main heat dissipation pipe for pumping the insulating oil, the insulating oil can be caused to circulate inside the machine body and the main heat dissipation pipe, so as to quickly dissipate the heat generated during operation in the machine body, which is beneficial to improving the working stability of each unit in the machine body. By adding multiple auxiliary heat dissipation pipes for the flow of insulating oil, it is beneficial to further improve the efficiency of heat dissipation in the machine body, thereby improving the cooling effect in the machine body.

[0036] (4) By inserting the sensing ends of multiple temperature control probes in sequence inside a group of adjacent main heat dissipation pipes and auxiliary heat dissipation pipes on the left side thereof, the temperature of the insulating oil in the main heat dissipation pipes and auxiliary heat dissipation pipes after cooling can be detected, thereby flexibly controlling the conduction of multiple auxiliary heat dissipation pipes layer by layer, so as to automatically adjust and use an appropriate amount of auxiliary heat dissipation pipes for cooling operations according to the actual working temperature in the machine body, thereby avoiding large-scale unified cooling that leads to increased energy consumption during equipment operation. By inserting the sensing ends of the temperature control probes in the direction of the water outlet inside the main heat dissipation pipes and auxiliary heat dissipation pipes, it is beneficial to improve the accuracy of the temperature control probe in determining the cooling demand in the machine body.

[0037] (5) By fixing the metal heat sink on the outside of the main heat sink and the auxiliary heat sink, and fixing a plurality of metal sheets on the outer surface of the metal heat sink, the contact area between the metal heat sink and the outside air can be effectively increased, thereby effectively accelerating the rate at which the heat of the insulating oil in the main heat sink and the auxiliary heat sink is dissipated outward, thereby facilitating the improvement of the heat dissipation effect of the device. By arranging the metal sheets horizontally on the outer surface of the metal heat sink, it is beneficial for the airflow generated by the heat dissipation fan to blow it, thereby ensuring the smoothness of the airflow passing through the metal sheets, thereby ensuring the stability of heat dissipation.

[0038] (6) By setting the shapes of the main heat dissipation pipe and the auxiliary heat dissipation pipe to a circular "S"-shaped structure, the coverage of the main heat dissipation pipe and the auxiliary heat dissipation pipe on the corresponding metal heat dissipation plate can be effectively improved. At the same time, by setting the overall thickness of the main heat dissipation pipe and the auxiliary heat dissipation pipe to a flat structure, the contact tightness of the main heat dissipation pipe, the auxiliary heat dissipation pipe and the metal heat dissipation plate can be ensured, which is conducive to ensuring that the heat in the main heat dissipation pipe and the auxiliary heat dissipation pipe is quickly transferred to the metal heat dissipation plate, so as to ensure the cooling and heat dissipation effect of the device.

[0039] (7) By installing a guide hood that is open outward between the cooling fan and the partition frame, the air intake of the device can be effectively increased, so as to further enhance the heat dissipation effect in the metal heat sink. By staggering multiple cooling fans at the front and rear ends of multiple partition frames, sufficient space can be provided for the guide hood that expands outward, so that the structure of the device is more compact and reasonable.

[0040] (8) By installing the one-way valve inside the water inlet and outlet of the main heat dissipation pipe and the auxiliary heat dissipation pipe, the insulating oil flow direction in the main heat dissipation pipe and the auxiliary heat dissipation pipe can be effectively guaranteed to be consistent, thereby avoiding interference in the circulation and cooling, and effectively improving the working stability of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] like Figure 1 As shown, embodiment 1 of the present invention provides a security identification device based on an industrial control protocol, comprising a body 1, wherein a main control unit and a backup control unit are sequentially installed inside the body 1, a plurality of execution units electrically connected to the main control unit are installed outside the body 1, and a checking unit is electrically connected between each execution unit and the main control unit, and the backup control units are electrically connected to the plurality of checking units through wires, and an alarm unit is fixedly installed on the outer surface of the body 1, and the alarm unit and the backup control unit are electrically connected through wires;

[0057] Specifically, the security identification device based on the industrial control protocol is as follows: Figure 3-10, including a cooling unit installed on a machine body 1, a main heat dissipation pipe 2 is fixedly installed at the bottom of the machine body 1, and a water outlet and a water inlet of the main heat dissipation pipe 2 are respectively fixedly connected to the outer end walls of the front and rear sides of the machine body 1, and the interior of the machine body 1 is filled with an appropriate amount of insulating oil, and a pump 201 is fixedly connected to the interior of the main heat dissipation pipe 2 close to its water inlet. When the device is working, the pump 201 is powered on and started to drive the insulating oil in the main heat dissipation pipe 2 to flow, so that the insulating oil circulates inside the machine body 1 and the main heat dissipation pipe 2, and the heat in the machine body 1 is dissipated outward through the main heat dissipation pipe 2. By connecting the main heat dissipation pipe 2 to the bottom of the machine body 1 and installing a pump 201 for pumping the insulating oil inside the main heat dissipation pipe 2, the insulating oil can be caused to circulate inside the machine body 1 and the main heat dissipation pipe 2, so as to quickly dissipate the heat generated when the machine body 1 is working, which is beneficial to improving the working stability of each unit in the machine body 1.

[0058] like Figure 3 and Figure 4 As shown, the bottom of the body 1 is sequentially fixedly connected with a plurality of auxiliary heat dissipation pipes 3 arranged side by side with the body 1, and the water outlet and the water inlet of the auxiliary heat dissipation pipe 3 are respectively fixedly connected to the outer end walls on the front and rear sides of the body 1, and the auxiliary heat dissipation pipe 3 is internally fixedly connected with a second pump 301 at one end close to the water inlet thereof. When the device is working, the second pump 301 is powered on and started to circulate the insulating oil in the body 1 through the auxiliary heat dissipation pipe 3. By adding a plurality of auxiliary heat dissipation pipes 3 to circulate the insulating oil, it is beneficial to further improve the efficiency of heat dissipation in the body 1, thereby improving the cooling effect in the body 1.

[0059] like Figure 5 , Fig. 9 and Fig.10 As shown, there are four auxiliary heat dissipation pipes 3 in total, and an electromagnetic valve 302 is fixedly installed on the inner end wall of each auxiliary heat dissipation pipe 3 near its water outlet, and a temperature control probe 303 is installed on the outer side of each electromagnetic valve 302. The sensing end of the temperature control probe 303 located on the far left is inserted on the inner wall of the main heat dissipation pipe 2 near the water outlet, and the sensing ends of the three temperature control probes 303 located on the right are sequentially inserted on the inner wall of the auxiliary heat dissipation pipe 3 adjacent to the left side near the water outlet. Multiple temperature control probes 303 are electrically connected to the electromagnetic valves 302 corresponding to them, and the pumps 2 301 arranged on the multiple auxiliary heat dissipation pipes 3 are electrically connected to the temperature control probes 303 corresponding to them. When the device is working, the pumps 2 301 and the electromagnetic valves 302 installed in the multiple auxiliary heat dissipation pipes 3 on the right are all in the non-starting state. At this time, only the main heat dissipation pipe 2 relies on the start of the pump 1 201 inside it to circulate the insulating oil in the body 1 to reduce the temperature in the body 1.

[0060] When the temperature of the insulating oil refluxed at the water outlet of the main heat dissipation pipe 2 is higher than the detection set temperature of the temperature control probe 303, the temperature control probe 303 inserted in the main heat dissipation pipe 2 controls the pump 2 301 and the electromagnetic valve 302 located on the right side of the main heat dissipation pipe 2 to start, so that the auxiliary heat dissipation pipe 3 located on the right side of the main heat dissipation pipe 2 performs an insulating circulation cooling operation on the body 1. Similarly, when the reflux temperature in the auxiliary heat dissipation pipe 3 arranged at an adjacent position on the right side of the main heat dissipation pipe 2 is too high, the temperature control probe 303 inside it controls another corresponding group of auxiliary heat dissipation pipes 3 to perform an insulating oil circulation operation. In a layer-by-layer progressive manner, multiple auxiliary heat dissipation pipes 3 are controlled. When the temperature control probe 303 detects that the corresponding temperature drops to an appropriate value, the corresponding pump 2 301 and the electromagnetic valve 302 are powered off to avoid additional cooling resulting in increased energy consumption of equipment operation, so that the device can flexibly perform cooling regulation according to the actual temperature in the body 1.

[0061] By sequentially inserting the sensing ends of multiple temperature control probes 303 inside a group of adjacent main heat dissipation tubes 2 and auxiliary heat dissipation tubes 3 located on the left side thereof, the temperature of the insulating oil in the main heat dissipation tubes 2 and the auxiliary heat dissipation tubes 3 after cooling can be detected, thereby flexibly controlling the conduction of multiple auxiliary heat dissipation tubes 3 layer by layer, so as to automatically adjust and use an appropriate amount of auxiliary heat dissipation tubes 3 for cooling operations according to the actual working temperature in the machine body 1, thereby avoiding large-scale unified cooling that leads to increased energy consumption during equipment operation. By inserting the sensing ends of the temperature control probes 303 in the direction of the water outlet inside the main heat dissipation tubes 2 and the auxiliary heat dissipation tubes 3, it is beneficial to improve the accuracy of the temperature control probe 303 in determining the cooling demand in the machine body 1.

[0062] like Figure 7 Figure 8 As shown, metal heat sinks 4 are fixedly mounted on the outer sides of the main heat sinks 2 and the auxiliary heat sinks 3, and a plurality of transversely arranged metal sheets are evenly fixed on the outer surfaces of the metal heat sinks 4. When the device is working, when the insulating oil flows in the main heat sinks 2 and the auxiliary heat sinks 3, the heat in the machine body 1 is transferred to the main heat sinks 2 and the auxiliary heat sinks 3 according to the flow of the insulating oil, and then is conducted to the metal heat sink 4, and is quickly conducted outwardly through a plurality of metal sheets evenly arranged on the metal heat sink 4. By fixing the metal heat sink 4 on the outer sides of the main heat sinks 2 and the auxiliary heat sinks 3, and fixing a plurality of metal sheets on the outer surfaces of the metal heat sink 4, the contact area between the metal heat sink 4 and the outside air can be effectively increased, thereby effectively accelerating the rate at which the heat of the insulating oil in the main heat sinks 2 and the auxiliary heat sinks 3 is dissipated outward, thereby facilitating the improvement of the heat dissipation effect of the device. By laterally arranging the metal sheets on the outer surfaces of the metal heat sinks 4, it is beneficial for the airflow generated in the heat dissipation fan 402 to blow it, thereby ensuring the smoothness of the airflow passing between the metal sheets, thereby ensuring the heat dissipation stability.

[0063] like Figure 4 and Figure 8As shown, the main heat dissipation tube 2 and the auxiliary heat dissipation tube 3 are both configured as a circulating "S"-shaped structure, and the overall thickness of the main heat dissipation tube 2 and the auxiliary heat dissipation tube 3 is configured as a flat structure. When the device is working, by configuring the main heat dissipation tube 2 and the auxiliary heat dissipation tube 3 as a circulating "S"-shaped structure, the coverage of the main heat dissipation tube 2 and the auxiliary heat dissipation tube 3 on the corresponding metal heat dissipation plate 4 can be effectively improved. At the same time, by configuring the main heat dissipation tube 2 and the auxiliary heat dissipation tube 3 as a flat structure, the contact tightness between the main heat dissipation tube 2, the auxiliary heat dissipation tube 3 and the metal heat dissipation plate 4 can be ensured, which is beneficial to ensure that the heat in the main heat dissipation tube 2 and the auxiliary heat dissipation tube 3 is quickly transferred to the metal heat dissipation plate 4, so as to ensure the cooling and heat dissipation effect of the device.

[0064] like Figure 7 As shown, a partition frame 401 is fixedly sleeved on the outer sides of the main heat dissipation pipe 2, the auxiliary heat dissipation pipe 3 and the metal heat dissipation plate 4, and a heat dissipation fan 402 is fixedly installed at one end of the partition frame 401. The heat dissipation fans 402 corresponding to the multiple auxiliary heat dissipation pipes 3 are electrically connected to multiple correspondingly arranged temperature control probes 303 through wires. When the device is working, the heat dissipation fans 402 are controlled by the temperature control probes 303 to start and blow air to the inside of the partition frame 401, thereby accelerating the rate at which heat on the metal heat dissipation plate 4 is dissipated outward.

[0065] like Figure 6 As shown, a plurality of cooling fans 402 are respectively arranged in an interval and staggered structure at the front and rear ends of a plurality of partition frames 401 in sequence, a guide cover 403 is fixedly installed between each cooling fan 402 and its corresponding partition frame 401, and the end of the guide cover 403 away from the partition frame 401 is open outwardly. When the device is working, the air intake of the device can be effectively increased by installing the guide cover 403 that is open outwardly between the cooling fan 402 and the partition frame 401, so as to further enhance the heat dissipation effect in the metal heat sink 4, and by staggering the plurality of cooling fans 402 at the front and rear ends of the plurality of partition frames 401, sufficient space can be provided for the guide cover 403 that expands outwardly, so as to make the structure of the device more compact and reasonable.

[0066] One-way valves are fixedly installed at the water inlet and outlet of the main heat dissipation pipe 2 and the auxiliary heat dissipation pipe 3. When the device is working, by installing the one-way valves inside the water inlet and outlet of the main heat dissipation pipe 2 and the auxiliary heat dissipation pipe 3, it can effectively ensure that the insulating oil in the main heat dissipation pipe 2 and the auxiliary heat dissipation pipe 3 flows in the same direction, avoids interference with its circulation flow and cooling, and effectively improves the working stability of the device.

[0067] like Figure 2 As shown, embodiment 2 of the present invention provides a security identification method based on an industrial control protocol, which specifically includes the following steps:

[0068] Step 1: The main control unit is provided with a protocol instruction, and when the main control unit inputs the instruction to the execution unit, the instruction is checked by the checking unit;

[0069] Step 2: When the checking unit checks that the instruction outputted in step 1 is correct, the instruction continues to be inputted into the execution unit for operation;

[0070] Step 3, when the checking unit checks that the instruction outputted in step 1 is incorrect, the checking unit intercepts the instruction outputted from the main control unit and receives the instruction inputted from the standby control unit;

[0071] Step 4: A backup protocol instruction is set in the backup control unit. When the instruction in the backup control unit is output successfully, the alarm unit is activated to remind the abnormal situation.

[0072] Step 5: When multiple checking units receive abnormal instructions from the main control unit, the backup control unit directly determines it as the highest level of abnormality and performs an emergency power-off.

[0073] The method for securely identifying an industrial control protocol, when in operation, when multiple checking units identify an instruction issued by a main control unit as an abnormal state, the backup instructions in the backup control unit will no longer be called. To avoid comprehensive instruction errors, the backup control unit is directly started, and the entire industrial control protocol is controlled to perform emergency stop processing by powering off, which can effectively reduce the losses caused by the equipment to which the protocol is applied during production.

[0074] The beneficial effect of the present invention is that, compared with the prior art, a security identification method and device based on industrial control protocols are provided, which realizes separate verification of the instructions received by each execution unit, and when the instruction verification is incorrect, the instruction on the backup control unit is enabled, and the alarm unit is triggered at the same time, so that the security identification method is more refined, which is beneficial to reducing the overall loss after the protocol is invaded. By installing the cooling unit on the machine body and automatically adjusting it according to the actual stability in the machine body, the operating efficiency of each unit in the machine body is improved, and energy consumption can be saved to a certain extent.

[0075] The above are only preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The heat dissipation fan (402) is powered on and started by controlling the temperature control probe (303), so as to blow air into the interior of the partition frame (401), thereby accelerating the rate at which heat on the metal heat dissipation plate (4) is dissipated outwards.

6. A security identification device based on industrial control protocol according to claim 5, characterized in that: One-way valves are fixedly installed at the water inlet and outlet of the main heat dissipation pipe (2) and the auxiliary heat dissipation pipe (3) to ensure that the insulating oil in the main heat dissipation pipe (2) and the auxiliary heat dissipation pipe (3) flows in the same direction.

7. A security identification method based on industrial control protocol applied to claim 1, characterized in that: The following steps are involved: Step 1: The main control unit is provided with a protocol instruction, and when the main control unit inputs the instruction to the execution unit, the instruction is checked by the checking unit; Step 2: When the checking unit checks that the instruction outputted in step 1 is correct, the instruction continues to be inputted into the execution unit for operation; Step 3, when the checking unit checks that the instruction outputted in step 1 is incorrect, the checking unit intercepts the instruction outputted from the main control unit, receives the instruction inputted from the standby control unit, and executes step 4; Step 4, a backup protocol instruction is set in the backup control unit. When the instruction in the backup control unit is output successfully, the alarm unit is activated to remind the abnormal situation; Step 5: When multiple checking units receive abnormal instructions from the main control unit, the backup control unit directly determines it as the highest level of abnormality and performs an emergency power-off.
