Description

Technical Field

[0001] The utility model relates to the technical field of communication, in particular to a communication system of a coagulation analyzer. Background Art

[0002] During the operation of the coagulation analyzer, communication between its independent components and with the client is an essential link. The client first sends instructions, which are parsed by the main control module of the coagulation analyzer and distributed to the independent components for corresponding operations. The components then feed back the data to the main control module through different communication methods, and the main control module then uploads the data to the client, thus completing the data interaction process between the client and the coagulation analyzer.

[0003] At present, most of the independent components use 485 or CAN communication. The 485 communication method is serial processing. Since there are many independent components in the coagulation analyzer and the communication methods between each independent component are different, the communication system structure is mostly one master and multiple slaves. The master station and the slave station are distinguished by address coding. In particular, the mechanism for handling data conflicts is host polling and the lower computer responds. Since the host polling method usually needs to wait for the response of all slave stations before the next data reading or writing operation can be performed. If there are a large number of slave stations, the polling time will be relatively long, which will slow down the entire communication process, and then lead to low communication efficiency between components.

[0004] Therefore, how to improve the communication efficiency between components has become an urgent problem to be solved in this field. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0030] like Figure 1 As shown, an embodiment of the utility model provides a schematic diagram of the architecture of a communication system of a coagulation analyzer, the communication system comprising: a network switching circuit board 11, a data acquisition circuit board 12, a main control circuit board 13 and a low-speed component 14;

[0031] The external network interface of the network switch circuit board 11 is connected to the client 15 .

[0032] The network switching circuit board 11 is used for data interaction with the client 15 .

[0033] Optionally, the external network interface includes but is not limited to: a multi-channel network interface (for example, a 2-channel network interface), each of which can be connected to the client 15. Not only can the client 15 be directly controlled on site, but it can also be easily connected to the local area network, facilitating unified management of the coagulation analyzer, and even remote data collection functions.

[0034] It should be noted that the external network interface of the network switching circuit board 11 is connected to the client 15 via a network cable.

[0035] The internal network interface of the network switching circuit board 11 is connected to the main control circuit board 13 .

[0036] The main control circuit board 13 is used to receive data and perform processing according to the data.

[0037] The network switching circuit board 11 is provided with a plurality of network interfaces (eg, 8 network interfaces), including an external network interface and an internal network interface, and information interaction between the client 15 and the communication system of the coagulation analyzer is realized through the plurality of network interfaces.

[0038] It should be noted that the internal network interface of the network switching circuit board 11 is connected to the network interface of the main control circuit board 13 via a shielded network cable. The shielded network cable includes but is not limited to: a high-quality shielded network cable.

[0039] It is understandable that transmitting data between circuit boards through high-quality shielded network cables can not only reduce the interference to key communication signals in the complex electromagnetic environment inside each circuit board, but also reduce the electromagnetic interference radiated by this communication method to the outside, thereby improving anti-interference and stability.

[0040] Furthermore, the main control circuit board 13 is provided with a high-speed network port chip and a main control chip.

[0041] The high-speed network port chip is connected to the main control chip through parallel port communication.

[0042] Among them, the high-speed network chip is used to achieve high-speed data communication; the main control chip is used to process data.

[0043] Optionally, the high-speed network port chip is specifically a W5300 chip; the main control chip is specifically a STM32F407 chip.

[0044] It should be noted that parallel communication refers to a parallel communication method, that is, a communication method that transmits multiple bits of data at the same time. Compared with serial communication, it can transmit more data at the same time and is usually used in situations where high-speed data transmission is required. Through parallel communication, fast data transmission between the client 15 is achieved.

[0045] The main control circuit board 13 is connected to the low-speed component 14 .

[0046] The low-speed component 14 is used to transmit data to the main control circuit board 13 .

[0047] Furthermore, the main control circuit board 13 is provided with a plurality of communication interfaces.

[0048] The main control circuit board 13 is connected to the low-speed component 14 through a plurality of communication interfaces.

[0049] Optionally, the communication interface is specifically a 485 interface or a CAN interface.

[0050] The low-speed component 14 includes but is not limited to: an incubation component, a sample addition component, and a reaction cup component.

[0051] It should be noted that the low-speed component 14 is a non-core component. Among the non-core components, since the non-core components are in the communication system to assist in processing data, there is no need to use a fast data transmission method, and only the data needs to be transmitted to the main control circuit board 13. Therefore, the 485 communication method or the CAN communication method is still used to reduce the complexity of the communication system while ensuring normal data transmission.

[0052] Optionally, the core component indicates the optical method test component, and the low-speed component 14 is mainly used to cooperate with the optical method test component to complete data testing, that is, data processing.

[0053] It can be understood that after the main control circuit board 13 receives the data sent by the data acquisition circuit board 12 and the low-speed component 14, it processes the data and completes the corresponding test.

[0054] Another internal network interface of the network switching circuit board 11 is connected to the data acquisition circuit board 12 .

[0055] The data acquisition circuit board 12 is used to collect data and send the data to the main control circuit board 13 .

[0056] It can be understood that the data collected by the data acquisition circuit board 12 can be used for subsequent data analysis, recording and reporting, and the data is sent to the main control circuit board 13 so that the main control circuit board 13 analyzes and processes the data.

[0057] Furthermore, the data acquisition circuit board 12 is provided with a high-speed network port.

[0058] It should be noted that the purpose of the data acquisition circuit board 12 being provided with a high-speed network port is usually to achieve fast and stable data transmission. Through the high-speed network port, the collected data can be more effectively transmitted to other circuit boards to achieve functions such as real-time monitoring, data sharing or remote access.

[0059] It should be noted that another internal network interface of the network switching circuit board 11 is connected to the network interface of the data acquisition circuit board 12 via a shielded network cable.

[0060] Furthermore, the network switching circuit board 11 at least includes a main control unit.

[0061] Among them, the main control unit is used to transmit data.

[0062] Optionally, the main control unit is specifically an RTL8309N chip.

[0063] It should be noted that in order to meet the communication needs between multiple circuit boards and the communication needs with the client 15, the network switching circuit board 11 is provided with multiple network channels. Since the RTL8309N chip supports up to 8-way network communication, the network switching circuit board 11 can be provided with 8-way network channels to ensure that the communication needs are met.

[0064] It is understandable that the network switching circuit board 11 adopts a multi-channel communication interface, so that the network switching circuit board 11 meets the needs of large-scale data throughput, and the communication protocol is relatively mature and has better stability. The communication method adopts a full-duplex operation mode, and data and instructions can be transmitted simultaneously, which improves communication efficiency.

[0065] It should be emphasized that the use of this communication method not only allows for more flexible processing of data from each component, but also has strong anti-interference capabilities and easy access to the network interface. Through the network interface, you only need to configure the network IP and port number reserved at the factory to easily connect to the coagulation analyzer, which is also a great convenience for users.

[0066] In summary, by grading the main control circuit board and each component, network interfaces are used for communication with high real-time requirements and large data volumes, while low-speed components still use 485 communication or CAN communication. This not only improves the communication efficiency between components, but also reduces the complexity of the system.

[0067] In some examples, another schematic diagram of the communication system of a coagulation analyzer is provided, such as Figure 2 As shown, the communication system includes: a network switching circuit board 11, a data acquisition circuit board 12, a main control circuit board 13 and a low-speed component 14.

[0068] The client 1 is connected to the network port 1 of the network switching circuit board 11 through a network cable, and the client 2 is connected to the network port 2 of the network switching circuit board 11 through a network cable.

[0069] Among them, the network port indicates the network interface.

[0070] The network port 3 of the network switching circuit board 11 is connected to the network port of the main control circuit board 13 through a network cable, and the network port 4 of the network switching circuit board 11 is connected to the network port of the data acquisition circuit board 12 through a network cable.

[0071] The 485 interface and the CAN interface of the main control circuit board 13 are connected to the low-speed component 14 .

[0072] In summary, by grading the main control circuit board and each component, network interfaces are used for communication with high real-time requirements and large data volumes, while low-speed components still use 485 communication or CAN communication. This not only improves the communication efficiency between components, but also reduces the complexity of the system.

[0073] Corresponding to the communication system of a coagulation analyzer provided in the above utility model embodiment, the utility model embodiment further provides a data processing method, which is applicable to the communication system of the coagulation analyzer mentioned in the above utility model, such as Figure 3 As shown, the following steps are included:

[0074] S301: After receiving the data processing instruction sent by the client, the data processing instruction is parsed through the network exchange circuit board to obtain parsed content, and the parsed content is sent to the data acquisition circuit board.

[0075] When a data processing instruction is received, it is parsed and identified. It will parse the content of the instruction according to the predefined protocol or rules, determine which components need to be set, and send the parsed content to the data acquisition circuit board.

[0076] S302: After receiving the parsed content, data is collected through the data collection circuit board and the data is transmitted to the main control circuit board.

[0077] Optionally, the data acquisition circuit board collects data in real time by connecting sensors, measuring devices, etc. These data may include various types of physical quantities such as temperature, humidity, pressure, position, speed, etc.

[0078] S303: Transmit data to the main control circuit board via the low-speed component.

[0079] It is understandable that some assisting data is provided by the low-speed components to assist the main control circuit board in completing data processing.

[0080] S304: When the data is received, the main control circuit board processes the data to obtain a processing result, and sends the processing result to the network switching circuit board.

[0081] It is understandable that by sending the processing results to the network switching circuit board, data can be transmitted from the main control circuit board to other devices or systems to achieve data sharing and communication. This is very important for multi-device collaboration, data synchronization and information exchange.

[0082] S305: After receiving the processing result, the processing result is fed back to the client through the network switching circuit board.

[0083] Feedback of the processing results to the client allows the client to respond accordingly, such as making further decisions based on the processing results, issuing control instructions, etc. This helps to achieve two-way interaction and communication between the system and the user.

[0084] To summarize, the client controls the circuit board to send data through data processing instructions, so that the main control circuit board processes the data and feeds back the processing results to the client to realize data interaction with the client. Through data interaction, data sharing and transmission can be realized, so that different devices or systems can share data and information, promoting information flow and collaboration.
