With the function of shutting down the computer system remotely, multiple computers on the network can be provided with security protection. When the mains fails, the application data is saved in time and the computer system is shut down before UPS5 can provide reasonable power supply protection.

[0050] Specifically, the freeze dryer with UPS monitoring function includes a freeze dryer body 1, an electrical cabinet 2, a monitoring computer, a communication cable 4, a UPS5, a UPS5 input cable 6, a UPS5 output cable 7, and a control module 8.

[0051] During operation, the freeze dryer cools down the material containing a large amount of water and freezes it into a solid in advance, and then allows water vapor to sublime directly from the solid under vacuum conditions, while the material itself remains in the frozen ice shelf, so that the dried product retains its original solid skeleton structure, maintains the original shape of the material, and the product has excellent rehydration properties.

[0052] The electrical cabinet 2 is located on the freeze dryer frame and provides power for the freeze dryer equipment. The cabinet is divided into a strong current part and a weak current part, including a main circuit breaker, a branch circuit breaker, a fuse, a transformer, a motor protector, an AC contactor, a solid-state relay, an intermediate relay, a key switch, etc. The three-phase electricity of the compressor, the circulating pump, the vacuum pump, the hydraulic pump and the heater belongs to the strong current part, and its circuit is the power circuit; the manual operating system such as the simulation diagram, the recording instrument, the PLC and the input and output module, the PC, the button switch and the key switch, etc., may also have a temperature control instrument, a vacuum measurement and control instrument, a touch screen, a touch switch, a button switch, etc. according to the configuration of different freeze dryers, and belongs to the weak current part, and its circuit belongs to the control circuit.

[0053] The monitoring computer must have a free communication port (RS232 or USB interface), at least 256MB of available hard disk space, Win10 system, and must install TCP / IP protocol, UPS5 monitoring software and freeze dryer monitoring software.

[0054] The communication cable 4 is divided into two types: RS232 and USB. The RS232 communication cable 4 communicates with the UPS 5 via the serial port (RS232), and can monitor up to 4 devices connected to the serial port at the same time; the USB communication cable 4 communicates with the UPS 5 via the USB port, and can monitor up to 32 devices connected to the USB communication at the same time. In actual use, the appropriate communication cable 4 can be selected according to needs.

[0055] Place UPS5 in a clean, vibration-free, well-ventilated environment away from water. Its total output power should not exceed 1kVA / 0.8kW (0.9kW), 2kVA / 1.6kW (1.8kW), 3kVA / 2.4kW (2.7kW). In addition to socket output, C3K also provides terminal block output. When the output current is greater than 10A, it is recommended to use terminal blocks for load wiring.

[0056] UPS5 input cable 6 is a three-core wire, including 220V+, 220V- and ground wire, connected to the mains; UPS5 output cable 7 is a three-core wire, including 220V+, 220V- and ground wire, connected to the load.

[0057] UPS5 monitoring software consists of three parts: Agent, Monitor, and Taskbar Icon, namely UPS Agent Unit, UPS Monitoring Unit, and UPS Taskbar Icon Unit. Agent is the core of the software, responsible for communicating with UPS5, recording UPS events, notifying users of abnormal events, performing certain operations according to user requirements, and shutting down the computer system and UPS5 when necessary; Monitor is the software user interface program, which communicates with Agent when running.

[0058] Through the user interface, users can view the real-time status information of UPS5, set UPS5 control parameters and shutdown parameters; the taskbar icon is a management tool for software operation, and is displayed in the status area of ​​the Windows system taskbar when running. The software monitors the status of UPS5 in real time. When the UPS5 status is abnormal, the software will issue an immediate alarm notification to protect key equipment and shut down the computer system normally, so that the protected equipment will not be seriously damaged by sudden failure of the mains power. The software has the function of remotely shutting down the computer system and can provide security protection for multiple computers on the network. When the mains power fails, the application data is saved in time and the computer system is shut down before the UPS5 can provide reasonable power supply protection.

[0059] Preparation before freeze drying: Power on the freeze dryer, turn on UPS5, and ensure that the freeze dryer is powered normally. Turn on the freeze dryer monitoring computer, start the UPS monitoring software, enter the real-time monitoring display mode, and confirm that the communication cable 4 signal is normal. After normal startup, you will see the corresponding software icon in the taskbar, indicating that the background service program is running normally

[0060] "Start Agent" starts the local agent; "Stop Agent" stops the local agent; "Start Monitor" starts the software interface; "Exit" exits the background service program.

[0061] Before setting up the UPS5 monitoring software, you must first become an administrator and change the password. The software defaults to non-administrators, who can only view permissions.

[0062] Select the device node to view the device's flow graph status, and the device's related parameters are also displayed in the flow graph.

[0063] Select the device node and enter the battery control parameter setting interface through the "Battery Control Parameters" item under the "Device" menu. The battery control parameter setting interface has different parameter item settings depending on the device. Some devices do not support battery control parameter settings. If the menu item of the selected device node is gray and cannot be selected, it means that the device does not support battery control parameter settings.

[0064] The software monitors the equipment and records abnormal events and real-time data of the equipment, which is convenient for subsequent maintenance personnel to analyze and view problems. The operation process is obtained through equipment data records and log records.

[0065] When the device is abnormal, the software can inform the user through different notification methods, so that the user can understand the device status in time and take corresponding preventive measures. The notification methods are mainly:

[0066] 1. Real-time alarm box notification;

[0067] 2. Email notification;

[0068] 3. Short message notification.

[0069] When an abnormality occurs in UPS5, the UPS5 output is turned off through the monitoring software. Five setting conditions can be used to turn off the UPS5 output through the software. When any of the following five conditions is met, the UPS5 output will be turned off.

[0070] Condition 1: UPS5 mains power is abnormal, battery backup time expires, and output is turned off;

[0071] Condition 2: When the UPS5 battery is at low potential, the output is turned off;

[0072] Condition 3: The remaining battery time of UPS5 is lower than the set time;

[0073] Condition 4: When the battery capacity of UPS5 is lower than the set value;

[0074] Condition 5: The user uses the scheduled shutdown function to set and control when the UPS5 turns off the output and when it turns on the normal output.

[0075] The settings of condition 1, condition 2, condition 3 and condition 4 are set through the "Shutdown parameter setting" interface.

[0076] To summarize, the freeze dryer with UPS monitoring function provided in the embodiment of the present application monitors the status of the UPS by connecting the UPS monitoring module and the control module to the UPS, compares the status information of the UPS with the pre-stored threshold, and issues an alarm or shuts down the UPS after exceeding the pre-stored threshold, so that the status of the UPS can be monitored in real time, and when an abnormality occurs in the UPS, it can be shut down.
