Problems solved by technology

[0003] There is a problem now. When a single sensor in the storage box detects abnormal data or fails, the controller cannot judge whether the current box system is operating normally. It will issue a parameter failure reminder, and the system may no longer operate normally. The system lacks the normal operating range of each parameter. If the judgment is made, it will be shut down for protection in a short period of time. After receiving the alarm, the management personnel should investigate the cause as soon as possible.
If a delay is found, the temperature in the box may rise, causing the item to deteriorate and fail

Embodiment 1

[0031] figure 1 One of the schematic flow charts of the operation control method according to the embodiment of the present invention is shown. like figure 1 As shown, the operation control method includes:

[0032] Step 101, acquiring multiple monitoring data collected by multiple sensors;

[0033] Step 102, determine whether any monitoring data in the plurality of monitoring data is abnormal; when it is determined that any monitoring data is abnormal, perform step 103;

[0034] Step 103, determine whether the cold storage device is in a normal state; if so, go to step 104;

[0035] Step 104, enter the safe operation mode.

[0036] In the operation control method provided by this embodiment, when any monitoring data in the plurality of monitoring data collected by the plurality of sensors is abnormal, it is considered that the system is in an unstable state and has a certain fault. At this time, it is further judged whether the cold storage device is in a normal state, a...

Embodiment 2

[0038] figure 2 The second schematic flowchart of the operation control method according to the embodiment of the present invention is shown. like figure 2 As shown, the operation control method includes:

[0039] Step 201, acquiring multiple monitoring data collected by multiple sensors;

[0040] Step 202, determine whether any monitoring data in the plurality of monitoring data is abnormal; when it is determined that any monitoring data is abnormal, perform step 203;

[0041] Step 203, determine whether the cold storage device is in a normal state; if so, go to step 204;

[0042] Step 204, enter the safe operation mode;

[0043] Step 205, determine the abnormal sensor corresponding to any monitoring data, and shield the monitoring data of the abnormal sensor;

[0044]Step 206, obtaining stable operation data of the cold storage equipment before the abnormality sensor occurs;

[0045] Step 207 , compare the stable operation data with the pre-stored experimental operat...

Embodiment 3

[0048] In the second embodiment, further, the operation strategy includes the compressor operation frequency and / or the on-off time ratio.

[0049] In this embodiment, it can be understood that the operation strategy includes, but is not limited to, the compressor operation frequency and / or the on-off time ratio.

Abstract

The invention provides an operation control method and device for cold storage equipment and the cold storage equipment. The operation control method comprises the following steps: acquiring a plurality of pieces of monitoring data acquired by a plurality of sensors; judging whether any monitoring data in the multiple monitoring data is abnormal or not; when it is judged that any monitoring data is abnormal, whether the cold storage equipment is in a normal state or not is judged; if yes, entering a safe operation mode. According to the operation control method provided by the invention, whether the system is in a normal state can be further judged after a certain sensor is judged to be abnormal or invalid, and if the system is still in the normal state, the system can be ensured to continuously and stably operate for a period of time by switching to the safe mode, so that shutdown protection in a short time is avoided; therefore, it is guaranteed that the system temperature does not fluctuate greatly, the deterioration risk of stored substances is reduced, and sufficient time is provided for a manager to conduct maintenance.

Description

technical field [0001] The invention belongs to the field of cold storage equipment, and in particular relates to an operation control method, control device and cold storage equipment for cold storage equipment. Background technique [0002] Medical refrigerators are used to store blood, proteins, bacteria, cells, bone marrow, nucleic acids, viruses, tissues and other items. The stored items are valuable, so the reliability of continuous and stable operation is high. [0003] There is a problem. When the detection data of a single sensor in the storage box is abnormal or invalid, the controller cannot judge whether the current box system is running normally, and will issue a parameter failure reminder, the system may no longer run normally, and the system lacks the normal operating range of each parameter. It will be shut down for protection in a short period of time, and managers should investigate the cause as soon as possible after receiving the alarm. If a delay is fo...
