Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, a schematic flow chart of a monitoring method of a refrigeration device according to an embodiment of the present application is shown, where the method is applied to a sample analyzer. Optionally, the sample analyzer is a blood routine + CRP all-in-one machine, and a latex reagent is stored in a refrigeration device of the sample analyzer at a preset temperature for CRP detection. It will be appreciated that the latex reagent plays an important role in the accuracy of the detection of CRP, and the storage temperature of the latex reagent is an important factor in ensuring that the latex reagent is not degraded. If the refrigeration device is abnormally operated and cannot be known by a user, the latex reagent may deteriorate, so that the result of the CRP detection is not desirable because the user does not know the reagent.
As shown in fig. 1, the monitoring method of the refrigeration apparatus specifically includes:
110: and acquiring the temperature information of the refrigerating device in a preset acquisition period.
Specifically, when the refrigeration device is working normally, the temperature sensor in the refrigeration device can also work normally. In other words, when the refrigeration device normally works, the temperature sensor can collect the temperature information of the refrigeration device in a preset collection period. If the refrigeration device cannot work normally when the power is off, the corresponding temperature sensor cannot acquire the temperature information of the refrigeration device.
In one embodiment, the temperature information may be a temperature value of the refrigeration device currently acquired by the temperature sensor. For example, if the temperature value of the refrigeration device is 1 degree, the temperature information currently collected by the temperature sensor is 1 degree.
120: storing the collected temperature information.
Specifically, the memory stores the collected temperature information.
130: and acquiring the quantity of the temperature information acquired in a preset time period.
Specifically, the preset time period may be a preset time period. Or may be a time period for triggering controller acquisition in a burst scenario, such as a power-off scenario. Or may be a time period of user input received by the sample analyzer. For example, the acquisition cycle is 10s, and the preset time period is 13: 00-13: 01, when the refrigerating device works normally, the number of the temperature information stored in the memory is 10. If the refrigerating device cannot work normally, the number of the temperature information stored in the memory is less than 10.
140: and determining the abnormal time of the refrigerating device according to the quantity of the collected temperature information.
Specifically, the abnormal time of the refrigeration device can be determined according to the quantity of the temperature information, so that a user can know whether the refrigeration device works abnormally in a preset time period, and can know whether the refrigeration device keeps the preset temperature in the preset time period to refrigerate the latex reagent so as to know whether the latex reagent is deteriorated and the CRP detection is affected, and the reliability of the sample analyzer is ensured.
According to the monitoring method of the refrigerating device, the temperature information of the refrigerating device is collected and stored in the preset period, the quantity of the collected temperature information in the preset time period is obtained, the abnormal time of the refrigerating device can be determined according to the quantity of the collected temperature information, and therefore the monitoring method of the refrigerating device capable of monitoring whether the refrigerating device works abnormally is provided.
Referring to fig. 2, a schematic flow chart of a monitoring method of another refrigeration device according to an embodiment of the present application is shown, where the method is applied to a sample analyzer. Optionally, the sample analyzer includes a main system power supply and a cooling device. In other words, when the main system power supply is powered off, the power supply of the refrigerating device may be powered off or may work normally, so that when the main system power supply is powered off, whether the refrigerating device works abnormally or not cannot be determined, and whether the latex reagent stored in the refrigerating device is deteriorated or not cannot be determined. The monitoring method of the refrigerating device can accurately acquire the abnormal time of the refrigerating device when the power supply of the main system is powered off.
As shown in fig. 2, the monitoring method of the refrigeration apparatus specifically includes:
210: and acquiring the temperature information of the refrigerating device in a preset acquisition period.
Specifically, when the refrigeration device is working normally, the temperature sensor in the refrigeration device can also work normally. In other words, when the refrigeration device normally works, the temperature sensor can collect the temperature information of the refrigeration device in a preset collection period. If the refrigeration device cannot work normally when the power is off, the corresponding temperature sensor cannot acquire the temperature information of the refrigeration device.
220: storing the collected temperature information.
Specifically, the memory stores the acquired temperature information and stores an acquisition time stamp corresponding to the acquired temperature information.
230: acquiring a power-off time period of a main system power supply; and counting the quantity of the temperature information in the power-off time period.
In the normal operation process of the refrigerating device, when temperature information is collected, the current temperature information collection times are accumulated according to the collected temperature information, and the collection time stamp for the temperature information and the accumulated temperature information collection times are stored in a correlation mode. The temperature information acquisition times and the acquisition time stamp corresponding to the acquired temperature information at each time can be stored. These temperature acquisition times and corresponding acquisition time stamps are stored in a memory in association. For example, the temperature information a1 is collected at the collection timestamp T1, the current temperature information collection times S are accumulated to obtain S +1, and the collection timestamps T1 and S +1 are stored in the memory in a correlated manner; further, when the temperature information a2 is collected at the next collection timestamp T2 of the collection timestamp T1, the current collection times S +1 of the temperature information are accumulated to obtain S +2, and the T2 and the S +2 are stored in the memory in an associated manner, which is repeated herein.
Optionally, the power-off time period of the main system power supply may be acquired as the preset time period when the main system power supply normally works after being powered off.
In one embodiment, when acquiring a power-off time period of a main system power supply, a start time stamp and an end time stamp of the power-off time period may be acquired; acquiring the accumulated temperature information acquisition times at the initial timestamp as a first count value; acquiring the temperature information collection times accumulated in the end timestamp as a second count value; and determining the quantity of the temperature information in the power-off time period according to the difference value of the second counting value and the first counting value. The method includes the steps that for a first counting value, a collection timestamp close to a starting timestamp can be obtained from collection timestamps stored in a pre-association mode, accumulated temperature information collection times having an association relation with the close collection timestamps are obtained, and the temperature information collection times are used as the first counting value. For the second count value, the collection timestamp close to the end timestamp may be obtained in the collection timestamps stored in advance in an associated manner, and then the accumulated temperature information collection times having an association relationship with the close collection timestamp may be obtained, and the temperature information collection times may be used as the second count value. And determining the quantity of the temperature information in the power-off time period according to the difference value of the second counting value and the first counting value.
For example, the power-off period is 13: 01-13: 49, and converting 13: 01 as the start timestamp, 13: 10 as the end timestamp. As shown in table 1: the acquisition time stamp stored in the memory comprises 13: 00. 13: 02. 13: 04. 13: 50. 13: 52. wherein with 13: the closest acquisition timestamp before 01 is 13: 00, thus 13: 00 as the acquisition timestamp close to the start timestamp, and further acquiring the data of 13: 00 the temperature information collection times after the correlation is accumulated is 156; the temperature information collection count 156 is taken as a first count value of the start time stamp. And 13: the closest acquisition timestamp before 49 is 13: 04, and therefore 13: 04 as the acquisition timestamp adjacent to the start timestamp, and further acquiring the data corresponding to the acquisition time of 13: 04 the number of times of acquiring the temperature information after the correlation is accumulated is 158; the temperature information collection count 158 is set as a second count value of the end time stamp. The difference 2 after subtracting the first count value 156 from the second count value 158 is determined as the power-off period 13 by the difference 2: 01-13: 49 temperature information. In other words, in the power-off period 13: 01-13: within 49, the number of temperature information collected is 2.
Table 1:
| acquisition time stamp | 13：00 | 13：02 | 13：04 | 13：50 | 13：52 |
| Number of times of temperature information acquisition | 156 | 157 | 158 | 159 | 160 |
In another embodiment, when acquiring the power-off time period of the main system power supply, a start time stamp and an end time stamp of the power-off time period may be acquired; and counting the quantity of the temperature information in the interval according to the starting time stamp and the ending time stamp.
240: and determining the abnormal time of the refrigerating device according to the quantity of the collected temperature information.
Optionally, the abnormal time of the refrigeration device is determined according to the number of the collected temperature information, the frequency of the collection cycle, and the duration of the preset time period. In one embodiment, the quantity of the collected temperature information, the frequency of a collection period and the duration of a preset time period are calculated based on an abnormal time formula to obtain the abnormal time of the refrigeration device; wherein, the abnormal time formula is as follows: t is1T-n/f; wherein, T1The time is the abnormal time of the refrigerating device, T is the duration of a preset time period, n is the number of collected temperature information, and f is the frequency of a collection period. Specifically, the power-off time period is used as a preset time period.
For example, the power-off period is 13: 01-13: 49, the corresponding time duration is determined to be 48 minutes, the number of the collected temperature information is 3 as shown in table 1, the frequency of the collection period is 1/2, and the abnormal time T is obtained148-2 x 2-44 minutes. In other words, in the power-off period 13: 01-13: in 49, the abnormal time of the refrigeration apparatus was 44 minutes. Therefore, the latex reagent is not stored at the preset temperature within 44 minutes, and then the deterioration of the latex reagent is judged, so that the latex reagent cannot be used for GRP detection.
250: if the abnormal time of the refrigerating device is zero, determining that the refrigerating device is in a normal running state; and if the abnormal time of the refrigerating device is greater than zero, outputting alarm information.
Specifically, if the abnormal time of the refrigeration device is greater than zero, it indicates that the refrigeration device is also powered off in the power-off time period, which affects the refrigeration of the latex reagent stored therein, and therefore alarm information is output to remind the user. Otherwise, it indicates that the refrigeration device is not powered off during the power-off period, and does not affect the refrigeration of the emulsion reagent stored therein.
The monitoring method for the refrigerating device provided by the embodiment of the application can accurately acquire the abnormal time of the refrigerating device in the power-off time period of the main system power supply without adding hardware under the scene that the main system power supply and the refrigerating device are not powered off synchronously, so that the monitoring method for the refrigerating device can monitor whether the refrigerating device works abnormally or not.
