Description

Technical Field

[0001] The present invention relates to the technical field of intelligent switch cabinets, and in particular to a control method and system for an intelligent switch cabinet. Background Art

[0002] Smart switchgear, especially high-voltage smart switchgear, is widely used in industrial scenarios and renewable energy power generation scenarios due to its superior control and communication functions. However, due to differences in usage scenarios, the locations of installed smart switchgear are different. For example, in industrial control scenarios such as steel and aluminum rolling, due to the large rolling site and the presence of many high-risk rolling processes, most smart switchgear in this scenario currently have separate distribution rooms to complete the high-voltage power distribution function of the rolling site and the communication control functions in different rolling process flows. In renewable energy power generation scenarios such as photovoltaic and wind power, due to the relatively remote location of the power plant, multiple distribution rooms are also configured to complete power generation and control functions. However, regardless of the application scenario, there may be smart switchgear installed in other locations independent of the distribution room to meet the power distribution and communication control needs of the application scenario.

[0003] To meet application requirements, smart switch cabinets in different application scenarios need to ensure the legitimacy and real-time nature of the data they receive. Therefore, for both smart switch cabinets located in the power distribution room and those located elsewhere outside the power distribution room, a control solution is needed to ensure that each smart switch cabinet receives data safely and in a timely manner. Summary of the Invention

[0004] The object of the present invention is to provide a control method and system for an intelligent switch cabinet, which can ensure the accuracy and security of data received by the intelligent switch cabinet under different application conditions, and can ensure the timeliness of communication control instruction transmission.

[0005] The present invention solves the technical problem and adopts the following technical solution:

[0006] In one aspect, the present invention provides a method for controlling an intelligent switch cabinet, comprising the following steps:

[0007] Obtain the location information of the intelligent switch cabinet in the workshop and the location information of the field monitoring components used to send wireless monitoring data;

[0008] Sending the wireless monitoring data acquired by the field component for sending the wireless monitoring data to the smart switch cabinet closest to the field component;

[0009] Based on the wireless monitoring data received by the smart switch cabinet and the location information of the target smart switch cabinet, a first communication transmission link is established between the current smart switch cabinet receiving the wireless monitoring data and the target smart switch cabinet, and the wireless monitoring data is forwarded to the target smart switch cabinet through the first communication transmission link;

[0010] Obtaining a control instruction of an actuator in the intelligent switch cabinet, and establishing a second communication transmission link for transmitting the control instruction to a target intelligent switch cabinet based on a source of the control instruction;

[0011] The target intelligent switch cabinet receives the wireless monitoring data and the wired monitoring data connected to the target intelligent switch cabinet, and obtains the on-site monitoring results based on the wireless monitoring data and the wired monitoring data;

[0012] When the target intelligent switch cabinet receives the control instruction, it obtains the cabinet monitoring results of the cabinet monitoring unit, adjusts the control instruction based on the on-site monitoring results, and transmits the adjusted control instruction to the execution element to control the execution element to complete the execution action.

[0013] Furthermore, the field monitoring element for transmitting wireless monitoring data includes an image acquisition device and a temperature sensor associated with the intelligent switch cabinet;

[0014] The image acquisition device associated with the intelligent switch cabinet is used to obtain the cabinet door opening and closing status information of the intelligent switch cabinet and the information of the person who performs the cabinet door opening and closing action;

[0015] The temperature sensor associated with the intelligent switch cabinet is used to collect temperature information before and after the cabinet door is opened and closed.

[0016] Furthermore, each of the intelligent switch cabinets that receives wireless monitoring data is provided with a receiving data threshold;

[0017] When the intelligent switch cabinet receives the cabinet door switch status information and the information of the person who performs the cabinet door switch action and / or the temperature information before and after the cabinet door switch action is performed, the received information is converted into a unified format, and the size of the space occupied by the data of the unified format information is calculated. When the size of the space occupied by the data is greater than the receiving data threshold, the intelligent switch cabinet is used as a communication node of the first communication transmission link.

[0018] Furthermore, the step of establishing a first communication transmission link between the current smart switch cabinet receiving the wireless monitoring data and the target smart switch cabinet includes:

[0019] Acquire a communication node of a first communication transmission link;

[0020] Setting a first standard communication distance based on location information of the communication node in the workshop;

[0021] When the distance between the current smart switch cabinet receiving the wireless monitoring data and the target smart switch cabinet is less than the first standard communication distance, a first communication transmission link is established between the current smart switch cabinet and the target smart switch cabinet for direct communication transmission, and the wireless monitoring data received by the current smart switch cabinet is directly sent to the target smart switch cabinet.

[0022] Furthermore, the step of establishing a first communication transmission link between the current smart switch cabinet for receiving wireless monitoring data and the target smart switch cabinet further includes:

[0023] When the distance between the current smart switch cabinet receiving the wireless monitoring data and the target smart switch cabinet is greater than the first standard communication distance, the smart switch cabinet closest to the target smart switch cabinet is obtained and used as the first intermediate communication node, and the distance between the first intermediate communication node and the target smart switch cabinet is less than the first standard communication distance;

[0024] Determine whether the distance between the current smart switch cabinet and the first intermediate communication node is less than the first standard communication distance. If it is less than, establish a first communication transmission link for communication transmission between the current smart switch cabinet, the first intermediate communication node and the target smart switch cabinet, and send the wireless monitoring data received by the current smart switch cabinet to the target smart switch cabinet through the first intermediate communication node.

[0025] Furthermore, the step of establishing a first communication transmission link between the current smart switch cabinet for receiving wireless monitoring data and the target smart switch cabinet further includes:

[0026] When the distance between the current intelligent switch cabinet and the first intermediate communication node is greater than the first standard communication distance, the intelligent switch cabinet closest to the first intermediate communication node is obtained and used as the second intermediate communication node, and the distance between the second intermediate communication node and the first communication node is less than the first standard communication distance;

[0027] Determine whether the distance between the current smart switch cabinet and the second intermediate communication node is less than the first standard communication distance. If it is less than, establish a first communication transmission link for communication transmission between the current smart switch cabinet, the first intermediate communication node, the second intermediate communication node and the target smart switch cabinet, and send the wireless monitoring data received by the current smart switch cabinet to the target smart switch cabinet through the second intermediate communication node and the first intermediate communication node.

[0028] Furthermore, when the distance between the current smart switch cabinet and the second intermediate communication node is greater than the first standard communication distance, the smart switch cabinet closest to the second intermediate communication node continues to be obtained and used as an additional intermediate communication node until the distance between the current smart switch cabinet and the additional intermediate communication node is less than the first standard communication distance, and the distance between the additional intermediate communication node and the second communication node is less than the first standard communication distance.

[0029] Furthermore, with the location information of the target smart switch cabinet as the starting point and the location information of the current smart switch cabinet as the end point, a straight line is drawn between the starting point and the end point. If there are multiple intermediate communication nodes obtained, the smart switch cabinet closest to the straight line is selected as the intermediate communication node.

[0030] Furthermore, the step of establishing a second communication transmission link for transmitting the control instruction to the target intelligent switch cabinet based on the source of the control instruction includes:

[0031] All intelligent switch cabinets in the workshop receive control instructions from the remote control terminal in real time, and set the second standard communication distance between each intelligent switch and the target intelligent switch cabinet;

[0032] If the source of the control instruction of the actuator in the smart switch cabinet is a remote control terminal, all smart switch cabinets within the second standard communication distance from the target smart switch cabinet are obtained, and the smart switch cabinet that receives the control instruction earliest is used as the communication node of the second communication transmission link, and the control instruction received by the communication node is forwarded to the target smart switch cabinet;

[0033] If the source of the control instruction of the actuator in the intelligent switch cabinet is the field control terminal, the location information of the field control terminal is obtained, and it is determined whether the distance between the field control terminal and the target intelligent switch cabinet is less than the second standard communication distance. If it is less, the control instruction is directly sent to the target intelligent switch cabinet. Otherwise, the midpoint position information of the direct connection line between the target intelligent switch cabinet and the field control terminal is selected, and the intelligent switch cabinet closest to the middle position information is selected as the forwarding communication node, and a second communication transmission link is established between the field control terminal, the forwarding communication node and the target intelligent switch cabinet, and the control instruction is forwarded to the target intelligent switch cabinet through the forwarding communication node.

[0034] On the other hand, the present invention further provides a control system for an intelligent switch cabinet, which is applied to the control method of the intelligent switch cabinet, comprising:

BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Figure 1 This is a flow chart of a control method for an intelligent switch cabinet in Example 1 of the present invention. DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations. Example 1

[0044] This embodiment provides a control method for an intelligent switch cabinet. Figure 1, wherein the method comprises the following steps:

[0045] S1. Obtain the location information of the intelligent switch cabinet in the workshop and the location information of the field monitoring element used to send wireless monitoring data;

[0046] S2. Sending the wireless monitoring data acquired by the on-site component for sending wireless monitoring data to the smart switch cabinet closest to it;

[0047] S3. Based on the wireless monitoring data received by the smart switch cabinet and the location information of the target smart switch cabinet, establish a first communication transmission link between the current smart switch cabinet receiving the wireless monitoring data and the target smart switch cabinet, and forward the wireless monitoring data to the target smart switch cabinet through the first communication transmission link;

[0048] S4. Obtain control instructions for the actuators in the intelligent switch cabinet, and establish a second communication transmission link for transmitting the control instructions to the target intelligent switch cabinet based on the source of the control instructions;

[0049] S5. The target intelligent switch cabinet receives the wireless monitoring data and the wired monitoring data connected to the target intelligent switch cabinet, and obtains the on-site monitoring results based on the wireless monitoring data and the wired monitoring data;

[0050] S6. When the target intelligent switch cabinet receives the control instruction, it obtains the cabinet monitoring result of the cabinet monitoring unit, adjusts the control instruction based on the on-site monitoring result, and transmits the adjusted control instruction to the execution element to control the execution element to complete the execution action.

[0051] In this embodiment, the control of the intelligent switchgear in a steel rolling mill is taken as an example for detailed description. Specifically, in this embodiment, for the steel rolling mill, there are both intelligent switchgear installed in the power distribution room and intelligent switchgear in other locations independent of the power distribution room.

[0052] Generally speaking, in the application scenario of this embodiment, in order to monitor whether the operation of the intelligent switch cabinet operation panel is illegal, whether the opening and closing status of the intelligent switch cabinet door is normal, and whether there are any hidden dangers of operation for nearby workers, most intelligent switch cabinets may be equipped with image acquisition devices. However, many intelligent switch cabinets may have internal actuators working at the same time, causing the temperature inside the cabinet to be too high, and it is necessary to open the cabinet door for heat dissipation, so that the temperature around the distribution room or the temperature at the location of the intelligent switch cabinet independent of the distribution room is higher than that at other locations. Therefore, temperature sensors will also be set for the distribution room and the location of the intelligent switch cabinet independent of the distribution room to monitor the temperature. However, since the cables at the steel rolling site itself are already relatively numerous, For image acquisition devices and temperature sensors, using cables for data transmission may increase the difficulty of maintenance, and improper cable installation may also lead to data loss or safety hazards. Therefore, both the image acquisition device and the temperature sensor may send relevant monitoring data to the corresponding smart switch cabinet in a wireless form. Therefore, in this embodiment, the field monitoring element for sending wireless monitoring data includes an image acquisition device and a temperature sensor associated with the smart switch cabinet; here, the image acquisition device associated with the smart switch cabinet is used to obtain the cabinet door switch status information of the smart switch cabinet and the information of the person who performs the cabinet door switch action; the temperature sensor associated with the smart switch cabinet is used to collect temperature information before and after the cabinet door switch action is executed.

[0053] Since the image acquisition device acquires image information and the temperature sensor acquires temperature information, the two forms of information are different, and image information requires a longer transmission time and processing time. In order not to add additional data memory or cache burden to the smart switch cabinet, when selecting the communication node of the first communication transmission link, it cannot be guaranteed that all smart switch cabinets meet the requirements of being a communication node. Therefore, in this embodiment, a receiving data threshold is set for each smart switch cabinet that needs to receive these two types of information to ensure the timeliness of data transmission. Therefore, in this embodiment, each smart switch cabinet that receives wireless monitoring data is provided with a receiving data threshold; when the smart switch cabinet receives the cabinet door switch status information and the information of the person who executes the cabinet door switch action and / or the temperature information before and after the cabinet door switch action is executed, the received information is converted into a unified format, and the size of the space occupied by the data of the unified format information is calculated. When the size of the space occupied by the data is greater than the receiving data threshold, the smart switch cabinet is used as the communication node of the first communication transmission link.

[0054] Here, no matter which smart switch cabinet is selected as the communication node of the first communication transmission link, the image information and temperature information it receives should be within a similar data size range after being unified in format. If other wireless data is accessed, it means that the data source may be illegal. Therefore, setting the receiving data threshold can also avoid the access of other irrelevant wireless data.

[0055] It should be noted that, in this embodiment, since the locations of the intelligent switch cabinets may be relatively dispersed and the working conditions of the rolling site are high, even if the first communication transmission link is established, the transmission distance between the communication nodes may be relatively long, resulting in delayed data transmission. Therefore, it is necessary to establish a standard communication distance, i.e., a first standard communication distance. Therefore, in this embodiment, the establishment of the first communication transmission link between the current intelligent switch cabinet receiving wireless monitoring data and the target intelligent switch cabinet may include:

[0056] Acquire a communication node of a first communication transmission link;

[0057] Setting a first standard communication distance based on location information of the communication node in the workshop;

[0058] When the distance between the current smart switch cabinet receiving the wireless monitoring data and the target smart switch cabinet is less than the first standard communication distance, a first communication transmission link is established between the current smart switch cabinet and the target smart switch cabinet for direct communication transmission, and the wireless monitoring data received by the current smart switch cabinet is directly sent to the target smart switch cabinet.

[0059] Therefore, in each communication node of the first communication transmission link, it is necessary to compare the communication transmission distance between the communication nodes with the first standard communication distance to meet the timeliness of wireless monitoring data transmission.

[0060] Therefore, establishing a first communication transmission link between the current smart switch cabinet receiving wireless monitoring data and the target smart switch cabinet may further include:

[0061] When the distance between the current smart switch cabinet receiving the wireless monitoring data and the target smart switch cabinet is greater than the first standard communication distance, the smart switch cabinet closest to the target smart switch cabinet is obtained and used as the first intermediate communication node, and the distance between the first intermediate communication node and the target smart switch cabinet is less than the first standard communication distance;

[0062] Determine whether the distance between the current smart switch cabinet and the first intermediate communication node is less than the first standard communication distance. If it is less than, establish a first communication transmission link for communication transmission between the current smart switch cabinet, the first intermediate communication node and the target smart switch cabinet, and send the wireless monitoring data received by the current smart switch cabinet to the target smart switch cabinet through the first intermediate communication node.

[0063] At the same time, the step of establishing a first communication transmission link between the current smart switch cabinet receiving wireless monitoring data and the target smart switch cabinet may further include:

[0064] When the distance between the current intelligent switch cabinet and the first intermediate communication node is greater than the first standard communication distance, the intelligent switch cabinet closest to the first intermediate communication node is obtained and used as the second intermediate communication node, and the distance between the second intermediate communication node and the first communication node is less than the first standard communication distance;

[0065] Determine whether the distance between the current smart switch cabinet and the second intermediate communication node is less than the first standard communication distance. If it is less than, establish a first communication transmission link for communication transmission between the current smart switch cabinet, the first intermediate communication node, the second intermediate communication node and the target smart switch cabinet, and send the wireless monitoring data received by the current smart switch cabinet to the target smart switch cabinet through the second intermediate communication node and the first intermediate communication node.

[0066] It should be pointed out that in this embodiment, when the distance between the current smart switch cabinet and the second intermediate communication node is greater than the first standard communication distance, the smart switch cabinet closest to the second intermediate communication node will continue to be obtained and used as an additional intermediate communication node until the distance between the current smart switch cabinet and the additional intermediate communication node is less than the first standard communication distance, and the distance between the additional intermediate communication node and the second communication node is less than the first standard communication distance.

[0067] It should be pointed out that when there are multiple intermediate communication nodes, only one smart switch cabinet needs to be selected. At this time, the location information of the target smart switch cabinet is used as the starting point, and the location information of the current smart switch cabinet is used as the end point. A straight line is drawn between the starting point and the end point. If there are multiple intermediate communication nodes obtained, the smart switch cabinet closest to the straight line is selected as the intermediate communication node.

[0068] In this embodiment, the second communication transmission link is a communication transmission link for the intelligent switch cabinet to receive control instructions. The control instructions may come from a remote control terminal or an on-site control terminal. Therefore, in this embodiment, establishing a second communication transmission link for transmitting the control instructions to the target intelligent switch cabinet based on the source of the control instructions may include:

[0069] All intelligent switch cabinets in the workshop receive control instructions from the remote control terminal in real time, and set the second standard communication distance between each intelligent switch and the target intelligent switch cabinet;

[0070] If the source of the control instruction of the actuator in the smart switch cabinet is a remote control terminal, all smart switch cabinets within the second standard communication distance from the target smart switch cabinet are obtained, and the smart switch cabinet that receives the control instruction earliest is used as the communication node of the second communication transmission link, and the control instruction received by the communication node is forwarded to the target smart switch cabinet;

[0071] If the source of the control instruction of the actuator in the intelligent switch cabinet is the field control terminal, the location information of the field control terminal is obtained, and it is determined whether the distance between the field control terminal and the target intelligent switch cabinet is less than the second standard communication distance. If it is less, the control instruction is directly sent to the target intelligent switch cabinet. Otherwise, the midpoint position information of the direct connection line between the target intelligent switch cabinet and the field control terminal is selected, and the intelligent switch cabinet closest to the middle position information is selected as the forwarding communication node, and a second communication transmission link is established between the field control terminal, the forwarding communication node and the target intelligent switch cabinet, and the control instruction is forwarded to the target intelligent switch cabinet through the forwarding communication node.

[0072] It should be pointed out that regardless of whether the control instruction comes from the remote control terminal or the on-site control terminal, due to the setting of the second standard communication distance, the second communication transmission link can be established, and the position difference between the intelligent switch cabinet receiving the instruction and the target intelligent switch cabinet is used as a communication node and compared with the second standard communication distance, and the position difference between the on-site control terminal and the target intelligent switch cabinet is compared with the second standard communication distance, so as to transmit the control instruction to the target intelligent switch cabinet through the corresponding second communication transmission link. Therefore, the timeliness of the target intelligent switch cabinet receiving the control instruction can be guaranteed. Example 2
