[0003]现有的国产前期生产灭菌设备,通常采用PLC作为主控及灭菌时间计时处理模块,其设定灭菌采集时间的过程需要用时1S,当出现灭菌开始时间和灭菌结束时间与采集时间不吻合时,会导致PLC记录的灭菌持续时间相比于实际的灭菌持续时间缺少1S,影响灭菌整体时长,导致质量风险难以评估
[0015] One technical advantage of this invention is that by setting up a data recording device independent of the equipment PLC, on the one hand, data can be recorded separately, thereby increasing the sampling frequency; on the other hand, it also avoids the 1-second delay caused by setting the time when using PLC recording, thus improving the accuracy of sterilization time setting.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sterilization equipment, and more specifically, to a data recording device for sterilization equipment. Background Technology
[0002] Current sterilization equipment in the pharmaceutical industry requires the collection of sterilization duration—a crucial parameter for sterilization effectiveness—during equipment operation. This data is used to calculate the F0 value (standard sterilization time) and to verify the effectiveness of the sterilization process. To ensure the accuracy of the sterilization duration, the equipment's timing accuracy must reach the second level.
[0003] Existing domestically produced sterilization equipment typically uses a PLC as the main control and sterilization time timing module. The process of setting the sterilization acquisition time takes 1 second. When the sterilization start time and sterilization end time do not match the acquisition time, the sterilization duration recorded by the PLC will be 1 second less than the actual sterilization duration, affecting the overall sterilization time and making it difficult to assess the quality risk. Utility Model Content
[0004] To improve the accuracy of sterilization time settings, this invention provides a data recording device for sterilization equipment.
[0005] This utility model provides a data recording device for sterilization equipment, comprising a data input module, a data conversion module, a data processing module, a database module, and a communication module.
[0006] The data input module is connected to the temperature sensor in the sterilization equipment to acquire the temperature data measured by the temperature sensor and transmit it to the data conversion module.
[0007] The data conversion module is used to convert the data type of the temperature data so that the temperature data can be recognized by the data processing module.
[0008] The data processing module is used to store the temperature data processed by the data conversion module into the database module;
[0009] The communication module is used to communicate with the host computer to transmit the temperature data stored in the database module to the host computer.
[0010] Optionally, the temperature sensor is a PT100, the data input module has an input current of 4-20mA and an input voltage of 0-5V.
[0011] Optionally, the data conversion module is an A / D conversion module, used to convert the data type of the temperature data from analog signal to digital signal.
[0012] Optionally, the data processing module supports running Windows or Linux systems.
[0013] Optionally, the communication module is connected to the host computer via a switch.
[0014] Optionally, the communication module and the switch are connected via an RS232 interface or an Ethernet connection.
[0015] One technical advantage of this invention is that by setting up a data recording device independent of the equipment PLC, on the one hand, data can be recorded separately, thereby increasing the sampling frequency; on the other hand, it also avoids the 1-second delay caused by setting the time when using PLC recording, thus improving the accuracy of sterilization time setting.
[0016] Another technical advantage of this invention is that when the PLC or host computer malfunctions, the data recording device can continue to record data. After the host computer recovers, it transmits the temperature data stored in the database module to the host computer through the communication module and performs data synchronization to restore the data and ensure the integrity of the equipment data.

[0026] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0028] This application discloses a data recording device for sterilization equipment. This data recording device is independent of the PLC in the sterilization equipment and is included in the sterilization equipment's data acquisition system. (Refer to...) Figure 1 The sterilization equipment data acquisition system also includes the sterilization equipment body 1, a temperature sensor 2 for collecting the sterilization temperature of the sterilization equipment, a switch 3, and a host computer 4. The data recording device is electrically connected to the temperature sensor 2 to acquire the temperature data collected by the temperature sensor 2. The data recording device and the sterilization equipment body 1 are respectively connected to the host computer 4 through the switch 3, and both have independent signal transmission paths.
[0029] Reference Figure 2 The data recording device includes a data input module, a data conversion module, a data processing module, a database module, and a communication module.
[0030] The data input module is connected to temperature sensor 2 to acquire the temperature data measured by temperature sensor 2 and transmit it to the data conversion module. Temperature sensor 2 can be a PT100 model. To match temperature sensor 2, the data input module is configured to support an input current of 4-20mA and an input voltage of 0-5V.
[0031] The data conversion module is used to convert the data type of temperature data so that it can be recognized by the data processing module. Specifically, the data conversion module can be an A / D conversion module, used to convert the temperature data from a time-continuous, amplitude-continuous analog signal into a time-discrete, amplitude-discrete digital signal.
[0032] The data processing module uses a CPU and supports running Windows or Linux systems. It stores the temperature data processed by the data conversion module into the database module. The database module can use a memory device, and the storage capacity of the memory device can be selected according to user needs.
[0033] The communication module is used to communicate with the host computer 4 to transmit the temperature data stored in the database module to the host computer 4. Specifically, the communication module can be connected to the switch 3 via an RS232 interface or an Ethernet connection, and then connected to the host computer 4 via the switch 3.
[0034] This application discloses a data recording device for sterilization equipment. By setting up a data recording device independent of the equipment's PLC, it can achieve separate data recording, thereby increasing the sampling frequency. Furthermore, it avoids the 1-second delay caused by setting the time when using PLC recording, improving the accuracy of sterilization time setting. In addition, when the PLC or host computer 4 malfunctions, the data recording device can continue to record data. After the host computer 4 recovers, it transmits the temperature data stored in the database module to the host computer 4 via the communication module and performs data synchronization to restore the data and ensure the integrity of the equipment data.
[0035] While specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
