A control method and system for a mine explosion-proof and intrinsically safe combined interconnection switch.

Abstract

This application provides a control method and system for a mine-use explosion-proof and intrinsically safe combined interconnection switch, belonging to the field of control technology. First, the communication control terminal receives a unified control command from the operating terminal and breaks it down into multiple target commands with a priority order. Then, based on the priority order, the communication channels between the communication control terminal and the execution switches are allocated. The execution switch corresponding to a higher-priority target command establishes a higher frequency band when establishing a communication connection with the communication control terminal. Finally, the communication control terminal sends the target command to the execution switch based on the allocated frequency band. The higher the priority of the target command, the higher the frequency band the execution switch uses to establish a communication connection with the communication control terminal. For the execution switch with the highest risk level, it occupies the highest frequency band among all communication-enabled frequency bands, thus its response speed is the fastest, minimizing the risk in the control process.

Description

It combines both explosion-proof and intrinsically safe technologies to ensure safe operation in hazardous environments.

[0003] Mining explosion-proof and intrinsically safe combination interconnection switches can perform a wide range of actions, making their control commands complex. In large mining areas, wired communication is more expensive than wireless communication. Furthermore, wireless communication can lead to interference between devices operating on the same frequency band. Summary of the Invention

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, embodiments of this application propose a control method for a mine-use explosion-proof and intrinsically safe combined interconnection switch, applicable to a switch control system.

[0008] The communication control terminal obtains the priority order based on the priority level of the target instructions;

[0009] The communication control terminal allocates communication channels between itself and the execution switches based on priority. The execution switch corresponding to the target instruction with higher priority shall use a higher frequency band when establishing a communication connection with the communication control terminal, and each execution switch shall exclusively occupy a frequency band when communicating with the communication control terminal.

[0010] The communication control terminal sends the target command to the execution switch based on the allocated frequency band, receives the execution data fed back by the execution switch, and sends the execution data to the operation terminal.

[0011] In conjunction with the first aspect, optionally, the communication control terminal sends the target instruction to the execution switch based on the allocated frequency band, and receives the execution data fed back by the execution switch, including:

[0012] The communication control terminal sends the target command to the execution switch based on the allocated frequency band, and acquires idle time and frequency resources at the same time as sending the target command. The idle time and frequency resources include the frequency band that is idle after the target command is sent.

[0013] The communication control terminal is based on priority order. When an idle frequency band appears, it uses the idle frequency band to establish a communication connection with the execution switch corresponding to the target instruction with the highest priority and receives the execution data fed back by the execution switch.

[0014] In conjunction with the first aspect, the method may optionally also include:

[0015] When the communication control terminal sends the corresponding target instruction to the execution switch, it generates a completion instruction and sends the completion instruction to the operation terminal, so that the operation terminal can establish a communication connection with multiple execution switches through the side link according to the completion instruction and directly obtain the execution data.

[0016] In conjunction with the first aspect, optionally, when the communication control terminal sends a completion command to the execution switch, a completion command is generated and sent to the operation terminal, so that the operation terminal can establish a communication connection with multiple execution switches via a side link according to the completion command and directly obtain execution data, including:

[0020] The communication control terminal determines the priority level of the target instruction based on the characters in the identifier field.

[0021] In conjunction with the first aspect, optionally, the priority order is the execution priority order. The communication control terminal allocates communication channels between the communication control terminal and the execution switches based on the priority order. Specifically, the execution switch corresponding to a higher priority target instruction establishes a higher frequency band when establishing a communication connection with the communication control terminal. Furthermore, each execution switch exclusively occupies one frequency band when communicating with the communication control terminal, including:

[0022] The communication control terminal acquires the frequency bands of all candidate channels and binds the target command with the lowest priority to the frequency band with the lowest frequency.

[0023] The communication control terminal binds target commands with increasing priority to multiple candidate frequency bands based on the frequency order from low to high corresponding to the candidate frequency bands.

[0024] Secondly, embodiments of this application propose a mine-use explosion-proof and intrinsically safe combined interconnection switch control system, applicable to a switch control system. The switch control system includes an operating terminal, a communication control terminal, and multiple execution switches. The multiple execution switches are communicatively connected to the communication control terminal and are used to receive control commands from the communication control terminal and to feed back execution data to the communication control terminal. The system is configured as follows:

[0025] The communication control terminal receives the overall control command from the operation terminal and breaks it down into multiple target commands, each of which corresponds to a specific execution switch.

[0026] The communication control terminal obtains the priority order based on the priority level of the target instructions;

[0027] The communication control terminal allocates communication channels between itself and the execution switches based on priority. The execution switch corresponding to the target instruction with higher priority shall use a higher frequency band when establishing a communication connection with the communication control terminal, and each execution switch shall exclusively occupy a frequency band when communicating with the communication control terminal.

[0028] The communication control terminal sends the target command to the execution switch based on the allocated frequency band, receives the execution data fed back by the execution switch, and sends the execution data to the operation terminal.

[0029] Optionally, the system is configured as follows:

[0030] The communication control terminal sends the target command to the execution switch based on the allocated frequency band, and receives the execution data fed back by the execution switch, including:

[0031] The communication control terminal sends the target command to the execution switch based on the allocated frequency band, and acquires idle time and frequency resources at the same time as sending the target command. The idle time and frequency resources include the frequency band that is idle after the target command is sent.

[0032] The communication control terminal is based on priority order.

Furthermore, each execution switch occupies a dedicated frequency band when communicating with the communication control terminal, including:

[0044] The communication control terminal acquires the frequency bands of all candidate channels and binds the target command with the lowest priority to the frequency band with the lowest frequency.

[0051] Figure 1 This is a flowchart illustrating a control method for a mine explosion-proof and intrinsically safe combined interconnection switch proposed in an embodiment of this application. Detailed Implementation

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] This application proposes a control method for a mine-use explosion-proof and intrinsically safe combined interconnection switch, applicable to a switch control system.

[0054] Specifically, the switch control system includes an operating terminal, a communication control terminal and multiple actuator switches. The multiple actuator switches are communicatively connected to the communication control terminal and are used to receive control commands from the communication control terminal and to feed back execution data to the communication control terminal.

[0055] For example, the operating terminal can be a PC, a host device, or other interactive terminals, and is not limited in this embodiment. The communication control terminal can be a wireless base station device or other communication hub device. In this embodiment, the actuators are distributed across a large open-pit mine area; in other embodiments, the actuators may be distributed in other scenarios, and is not limited in this embodiment.

[0056] In this embodiment, the actuator switch can be a mining explosion-proof and intrinsically safe combination interconnection switch, used in electrical equipment in flammable and explosive environments such as coal mines, mainly for control and protection circuits.

[0057] The method proposed in this application includes the following steps:

[0058] S101: The communication control terminal receives the overall control command from the operation terminal and breaks down the overall control command into multiple target commands, each of which corresponds to a specific execution switch.

[0059] Understandably, when controlling multiple actuator switches in combination, the operating terminal first needs to determine the execution order or execution method, such as switching on and off, or instantaneous closing (opening) or delayed closing (opening). Therefore, the instruction to coordinate all switches is completed by the operating terminal, which can be manually or intelligently selected, and is not limited in this embodiment. This overall control instruction can be received by the communication control terminal and forwarded to each actuator switch.

[0060] Specifically, as one implementation method, the communication control terminal receives a unified control instruction from the operation terminal. The unified control instruction includes multiple data fields and multiple identification fields. Each data field corresponds to an identification field and together they form a target instruction. Then, the communication control terminal determines the priority level corresponding to the target instruction based on the characters in the identification fields.

[0061] Understandably, these control commands contain multiple data fields and multiple identifier fields, with each data field corresponding to one identifier field. This mapping allows each data field to be matched with a target command. The communication control terminal can determine the priority level of each target command based on the characters in the identifier field.

[0062] S102: The communication control terminal obtains the priority order based on the priority level of the target instruction.

[0063] Understandably, for each execution switch, due to its different location or the different functions it needs to perform, communication delays exist during the execution of specific operations. For an execution switch, the longer the communication delay, the higher the risk. Therefore, different execution switches have corresponding risk levels. That is, target instructions with higher priority need to be executed first to ensure that the risk during execution is minimized.

[0064] S103: The communication control terminal allocates communication channels between the communication control terminal and the execution switch based on priority. The execution switch corresponding to the target instruction with higher priority shall use a higher frequency band when establishing a communication connection with the communication control terminal, and each execution switch shall exclusively occupy a frequency band when communicating with the communication control terminal.

[0065] Understandably, in this embodiment, the communication control terminal is wirelessly connected to multiple execution switches. To avoid problems such as signal interference, each execution switch exclusively occupies a frequency band with the communication control terminal.

[0066] In wireless communication, higher frequencies correspond to faster data transmission speeds. Therefore, in this embodiment, the execution switch corresponding to a higher-priority target instruction establishes a communication connection with the communication control terminal at a higher frequency. Thus, the execution switch with the highest risk level occupies the highest frequency among all communication-enabled frequency bands, resulting in the fastest response speed. This minimizes the risks associated with communication delays.

[0067] Of course, in other embodiments, priority can also refer to the order of execution. For example, switch A must perform a certain action before switch B can perform the corresponding action; that is, higher-priority target instructions need to be executed first. It is understandable that higher frequency bands have faster response speeds, but also shorter transmission distances, and excessively high frequency bands may lead to data loss. Therefore, in this embodiment, all frequency bands that the communication control terminal and the execution switches can establish connections with are candidate frequency bands. After acquiring the frequency bands of all candidate channels, the communication control terminal can first bind the lowest-priority target instruction to the lowest-frequency band, and then bind target instructions with progressively higher priorities to multiple candidate frequency bands based on the ascending frequency order of the candidate frequency bands. This prioritizes the use of low-frequency bands, ensuring the accuracy of data transmission. Simultaneously, since higher-priority target instructions are transmitted through higher frequency bands, their priority is also guaranteed.

[0068] S104: The communication control terminal sends the target command to the execution switch based on the allocated frequency band, receives the execution data fed back by the execution switch, and sends the execution data to the operation terminal.

[0069] Understandably, the above method allows the target command to be sent to the execution switch and executed within the allocated frequency band. Sometimes, after the execution switch completes its operation, it needs to provide feedback on execution data, such as the current status of the execution switch or other data. This data needs to be received by the operating terminal.

[0070] In this embodiment, as one implementation method, the communication control terminal sends the target instruction to the execution switch based on the allocated frequency band, and simultaneously acquires idle time-frequency resources, including the frequency band that becomes idle after the target instruction is sent. Then, based on priority, when an idle frequency band appears, the communication control terminal uses the idle frequency band to sequentially establish a communication connection with the execution switch corresponding to the target instruction with the highest priority, and receives the execution data fed back by the execution switch.

[0071] Understandably, the above method effectively utilizes idle time and frequency resources. When executing a large number of switches, it also avoids overlap between transmission frequency bands as much as possible to prevent signal interference.

[0072] In other implementations, since the amount of execution data is small, the operating terminal can also be directly connected to multiple execution switches via a side link, and the execution data can be received by the side link.

[0073] Understandably, when the communication control terminal sends a completion command to the execution switch, it generates a completion command and sends it to the operation terminal. This allows the operation terminal to establish communication connections with multiple execution switches via the side link based on the completion command and directly obtain execution data. Of course, when establishing connections via the side link, the operation terminal can also establish communication connections with the corresponding execution switches sequentially according to the priority level of the target command.

[0074] This application proposes a control method for a mine-use explosion-proof and intrinsically safe combined interconnection switch. First, a communication control terminal receives a unified control command from an operating terminal and breaks it down into multiple target commands with a priority order. Then, based on the priority order, the communication channels between the communication control terminal and the execution switches are allocated. The execution switches corresponding to higher-priority target commands establish communication connections with the communication control terminal at higher frequencies. Finally, the communication control terminal sends the target commands to the execution switches based on the allocated frequency bands, receives execution data from the execution switches, and sends the execution data back to the operating terminal. In this mine-use explosion-proof and intrinsically safe combined interconnection switch control method, the execution switches corresponding to higher-priority target commands establish communication connections with the communication control terminal at higher frequencies. For the execution switches with the highest risk level, the highest frequency band among all communication-enabled frequency bands is occupied, resulting in the fastest response speed and the lowest risk during the control process.

[0075] Based on the same inventive concept, this application also proposes a mine-use explosion-proof and intrinsically safe combined interconnection switch control system, applicable to a switch control system. The switch control system includes an operating terminal, a communication control terminal, and multiple execution switches. The multiple execution switches are communicatively connected to the communication control terminal and are used to receive control commands from the communication control terminal and to feed back execution data to the communication control terminal. The system is configured as follows:

[0076] The communication control terminal receives the overall control command from the operation terminal and breaks it down into multiple target commands, each of which corresponds to a specific execution switch.

[0078] The communication control terminal allocates communication channels between itself and the execution switches based on priority. The execution switch corresponding to the target instruction with higher priority shall use a higher frequency band when establishing a communication connection with the communication control terminal, and each execution switch shall exclusively occupy a frequency band when communicating with the communication control terminal.

[0079] The communication control terminal sends the target command to the execution switch based on the allocated frequency band, receives the execution data fed back by the execution switch, and sends the execution data to the operation terminal.

The idle time and frequency resources include the frequency band that is idle after the target command is sent.

[0083] The communication control terminal is based on priority order. When an idle frequency band appears, it uses the idle frequency band to establish a communication connection with the execution switch corresponding to the target instruction with the highest priority and receives the execution data fed back by the execution switch.

First, the communication control terminal receives a unified control command from the operation terminal and breaks it down into multiple target commands with a priority order. Then, based on the priority order, the communication channels between the communication control terminal and the execution switches are allocated.
