Fig. 1 schematically illustrates an exemplary system architecture to which the alert method and apparatus for cold chain transportation scenarios of the present disclosure may be applied. It should be noted that fig. 1 is only an example of a system architecture to which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, and does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, a system architecture 100 according to this embodiment may include a transportation vehicle 101, a temperature monitoring system 102 provided by a vehicle manufacturer, a temperature monitoring system 103 provided by a logistics company, and a big data computing platform 104.
Among them, the transport vehicle 101 is provided with a temperature sensor 1011 and a refrigerator 1012. Among them, the refrigerator 1012 is used to cool a refrigerating space provided in the transport vehicle 101. The temperature sensor 1011 is used to collect the ambient temperature in the refrigerated space provided on the transport vehicle 101 and transmit the collected ambient temperature to the temperature monitoring system 102.
The temperature monitoring system 102 is configured to obtain an ambient temperature from each transport vehicle, determine whether an abnormal temperature is currently present in a refrigerating space of each transport vehicle, and transmit temperature abnormality information to the temperature monitoring system 103.
The temperature monitoring system 103 is used for acquiring temperature anomaly information, accessing the acquired temperature anomaly information to the big data computing platform 104, performing operation and analysis through the big data computing platform 104 so as to filter invalid alarm information, leave valid alarm information, and output valid alarm information for alarm.

Accordingly, the alerting device for cold chain transportation scenarios provided by embodiments of the present disclosure may be generally disposed in the big data computing platform 104.
It should be understood that the number of transport vehicles 101, temperature monitoring systems 102 and 103, and big data computing platforms 104 in FIG. 1 are merely illustrative. There may be any number of transport vehicles 101, temperature monitoring systems 102 and 103, and big data computing platforms 104, as desired for an implementation.
Fig. 2A to 2C schematically show application scenarios of the alarm method according to the embodiment of the present disclosure.
As shown in fig. 2A to 2C, the cold chain transport vehicle 200 includes a partition 201 for enclosing a refrigerating space, a condenser 202 and an evaporator 203 for constituting a refrigerator, and a temperature sensor 204 for collecting an ambient temperature in the refrigerating space.
As shown in fig. 2A, when loading is started, a refrigerator on the cold chain transport vehicle 200 (refrigerator car) is turned on to perform cooling, and this process is a pre-cooling process. The environmental temperature in the cold storage space in the precooling process cannot reach the temperature in a specific temperature zone range preset for the transportation process, and the method belongs to a normal precooling link. This link does not require an alarm.
For example, the commodity a needs to be refrigerated in a 0-10 ° refrigeration environment to ensure the quality of the commodity, but in the loading stage (i.e. the precooling stage), if the actual temperature in the refrigeration environment is 15 °, the normal phenomenon occurs. At this point no alarm is required.
As shown in fig. 2B, the cold chain transport vehicle 200 does not need to perform whole-course refrigeration during transportation, and only needs to start the refrigerator to perform refrigeration when the refrigeration temperature does not meet the transportation requirement. For this reason, the refrigerating temperature of the cold chain transport vehicle 200 may fluctuate during transportation, and such fluctuation may cause the refrigerating temperature to fail the transportation requirement for a short time. When the refrigerating temperature does not meet the requirement, the temperature sensor 204 will transmit back the abnormal temperature information, but the abnormality needs to be ignored actually. I.e. no alarm is required at this time.
For example, the commodity a needs to be refrigerated in a 0-10 ° refrigeration environment to ensure the quality of the commodity, but in the transportation stage (i.e. after the loading is completed), if the actual temperature in the refrigeration environment is 11 ° and automatically returns to 10 ° after 1 minute, it is a normal phenomenon. At this point no alarm is required.
As shown in fig. 2C, after the unloading in the current transportation, no commercial product is available on the cold chain transport vehicle 200 until the next transportation and loading. At this time, even if the refrigerating temperature does not meet the requirement, the temperature sensor 204 will send back the abnormal temperature information, and the abnormality should be ignored. I.e. no alarm is required at this time.
For example, the commodity a needs to be refrigerated in a 0-10 ° refrigeration environment to ensure the quality of the commodity, but after unloading, if the actual temperature in the refrigeration environment is 11 °, the normal phenomenon also exists. At this point no alarm is required.
However, for the scenarios shown in fig. 2A to 2C, the related art cannot distinguish whether the anomaly needs to be alarmed. By the alarm scheme provided by the embodiment of the disclosure, which anomalies can be filtered out can be distinguished, no alarm is needed, and which anomalies should not be filtered out need to be alarmed normally.
The present disclosure will be described in detail below with reference to specific examples.
Fig. 3-5 schematically show flow charts of an alerting method according to an embodiment of the present disclosure.
Example one
As shown in fig. 3, the method may include operations S301 to S302.
In operation S301, it is determined whether goods are currently in a refrigerated space of a vehicle for cold chain transportation when a first event occurs, wherein the first event indicates that a current ambient temperature in the refrigerated space does not reach a temperature within a preset temperature zone.
In operation S302, in response to determining that there is no item currently within the refrigerated space, no alert is made for the first event.
Example two
As shown in fig. 4, the method may include operations S401 to S405.
In operation S401, when a first event occurs, which indicates that the current ambient temperature in the refrigerated space does not reach the temperature within the preset temperature zone range, the time starting point of the occurrence of the first event is recorded and it is determined whether the refrigerated space of the vehicle for cold chain transportation is currently in the in-transit phase.
Operation S402, in response to determining that the refrigerated space is currently in the in-transit phase, performing the following operations every preset time from the time start (i.e., operations S403 to S405):
in operation S403, it is detected whether the first event is still continuing.
In operation S404, in response to detecting that the first event is still continuing, it is determined whether the duration of the first event has reached a first preset value.
In operation S405, if it is determined that the duration of the first event has not reached the first preset value, no alarm is performed with respect to the first event.
EXAMPLE III
As shown in fig. 5, the method may include operations S501 to S502.
In operation S501, it is determined whether a refrigerated space of a vehicle for cold chain transportation is currently in a pre-cooling stage when a first event occurs, where the first event indicates that a current ambient temperature in the refrigerated space does not reach a temperature within a preset temperature zone range.
In operation S502, in response to determining that the refrigerating space is currently in the pre-cooling stage, no warning is given for the first event.
It should be noted that, in the embodiment of the present disclosure, the preset temperature range may be determined according to the type of goods loaded on the vehicle. Different types of goods need to be stored in different refrigerated environments to ensure their quality. In addition, the current ambient temperature in the refrigerating space not reaching the temperature within the preset temperature zone includes the current ambient temperature being lower than the lowest temperature of the preset temperature zone and being higher than the highest temperature of the preset temperature zone.
It should be understood that the occurrence of the first event in the loading step, or the occurrence of the first event in the transportation step due to temperature fluctuation, or the occurrence of the first event in the case where no goods are loaded after unloading, can be regarded as a normal phenomenon, and no alarm is required.
Based on this, in the embodiment of the present disclosure, when the first event occurs, it may be determined whether one of the following occurs: currently in the loading link (as in example three); currently, the method is in a transportation link and belongs to normal temperature fluctuation (as in the second embodiment); no goods are currently loaded on the refrigerated vehicle (as in example one). If it is determined that one of the above conditions occurs, the alarm information is filtered, i.e., no alarm is made.
It should be noted that, for the above three cases, the disclosed embodiment does not limit the determination order for each case. For example, whether the goods are currently loaded on the refrigerator car can be judged firstly, whether the goods are currently loaded on the refrigerator car can be judged continuously under the condition that the goods are not currently loaded, whether the goods are currently loaded on the refrigerator car or not and whether the normal temperature fluctuation exists can be judged continuously under the condition that the goods are not currently loaded on the refrigerator car.
Specifically, in the first embodiment, whether goods are loaded on the vehicle currently can be indirectly monitored by determining whether the associated order bound with the refrigerated vehicle exists and determining whether the associated order bound with the refrigerated vehicle is currently in an order loaded state. And if the associated order bound with the refrigerated truck exists and the associated order bound with the refrigerated truck is currently in a loaded freight note state, the truck is considered to be currently loaded with goods. Otherwise, it is assumed that no goods are currently loaded on the vehicle.
Specifically, in the second embodiment, since the whole process of refrigeration is not performed during transportation, the refrigerator is turned on only when the refrigeration temperature fluctuates to perform refrigeration. And when the refrigerating temperature fluctuates, the refrigerating temperature in the refrigerating space can be adjusted to be within the preset transportation temperature range after the refrigerator is started under the normal condition for a certain time. If the refrigerating temperature in the refrigerating space cannot be adjusted to be within the preset transportation temperature range after a certain time, the fact that the refrigerator is possibly broken down is indicated, and at the moment, an alarm needs to be given out so that a worker can conveniently check the related temperature problem. Therefore, in the second embodiment, when the first event occurs at the transportation link, it is possible to record the time when the first event occurs and detect whether the duration of the first event exceeds the time (first preset value) theoretically consumed to restore the refrigerating temperature to the temperature within the preset transportation temperature zone. And if the duration time of the first event is detected not to exceed the time consumed for theoretically restoring the refrigerating temperature to the temperature within the preset transportation temperature range, namely the first event is ended within the expected time period, filtering the alarm information and not alarming. Otherwise, if it is detected that the duration of the first event exceeds the time consumed for theoretically restoring the refrigerating temperature to the temperature within the preset transportation temperature range, that is, the first event is not ended within the expected time period, the alarm information cannot be filtered, and an alarm needs to be given, so that the staff can conveniently troubleshoot the relevant temperature problem.
It should be noted that, in the embodiment of the present disclosure, the model of the refrigerator car and the refrigeration power of the refrigerator installed thereon may be measured and calculated through big data analysis, so as to calculate how long (the first preset value) the refrigeration temperature needs to reach the preset transportation temperature region that is required to be met by the transported goods again when the temperature of the car fluctuates during transportation.
Specifically, in the third embodiment, whether the vehicle is currently in a precooling link (loading link) can be indirectly monitored by determining whether the associated order bound with the refrigerated vehicle exists and determining whether the associated order bound with the refrigerated vehicle is currently in an order loading state. And if the associated order bound with the refrigerated vehicle exists and the associated order bound with the refrigerated vehicle is currently in an order carrying and loading state, the vehicle is considered to be currently in a precooling link.
It should be noted that, in the embodiment of the present disclosure, the model of the refrigerator car and the refrigeration power of the refrigerator installed thereon may be measured and calculated through big data analysis, so as to calculate how long the vehicle can reach the preset transportation temperature region (i.e., how long the refrigeration link needs to last) that the refrigeration temperature can reach the requirement of the transported goods again after the refrigerator is started. Moreover, in the embodiment of the disclosure, it can also be determined by big data analysis how long various goods can be stored at most without going bad in the non-refrigeration environment. Thus, it can be determined when the refrigerator is turned on and when loading is started, and the safety of goods can be guaranteed.
In one embodiment of the present disclosure, the time for turning on the refrigerator may be taken as the starting time of the pre-cooling stage. Alternatively, in another embodiment of the present disclosure, the time for starting loading may be used as the starting time of the pre-cooling stage. The time for starting loading can be the time for triggering the freight note to be in a loading state. The required duration of the refrigeration cycle may be determined according to the above method. In one embodiment of the present disclosure, the end time of the pre-cooling stage may be calculated based on the start time of the pre-cooling stage and the duration of the refrigeration stage. Alternatively, in another embodiment of the present disclosure, the time when the waybill is triggered to the loading completion state (the vehicle-sealing state) may be used as the end time of the pre-cooling link.
Alternatively, in one embodiment of the present disclosure, the state of the door of the refrigerator car may be determined by detecting the door magnetism, and the time for opening the door may be regarded as the start time of the pre-cooling link, and the time for closing the door may be regarded as the end time of the pre-cooling link.
By the aid of the method and the device, precooling starting time, precooling duration and precooling ending time of the vehicle can be accurately captured, and a time period in which the vehicle precooling does not need to be alarmed is established, so that invalid alarm information in a precooling link is effectively filtered, and working efficiency of workers is improved.
In addition, in the embodiment of the disclosure, related invalid alarm information can be filtered during transportation.
It should be appreciated that in embodiments of the present disclosure, when the pre-cool time for the vehicle is over, the vehicle begins to enter the in-transit time period, at which point the pre-cool end time is recorded as the in-transit start time.
As an alternative embodiment, the method may further include the following operations.
When a first event occurs, the time origin at which the first event occurred is recorded.
In response to determining that the refrigerated space is not currently in the pre-cool phase, it is determined whether the refrigerated space is currently in the in-transit phase.
In response to determining that the refrigerated space is currently in the in-transit phase, performing the following operations at preset time intervals from the start of time:
it is detected whether the first event is still persisting.
In response to detecting that the first event is continuing, it is determined whether a duration of the first event has reached a first preset value.
And if the duration of the first event is determined not to reach the first preset value, not alarming aiming at the first event.
Or, as an alternative embodiment, the method may further include the following operations: and if the duration of the first event is determined to reach the first preset value, alarming is carried out aiming at the first event.
Specifically, in the disclosed embodiment, it may be determined whether the vehicle is currently in a pre-cooling phase. If it is determined that the vehicle is not currently in the pre-cooling phase, the determination of whether the vehicle is currently in the transportation phase may continue. If the vehicle is determined to be in the transportation stage currently, whether corresponding warning information is filtered out or not can be determined according to the processing logic for judging whether warning is required or not in the transportation stage.
For example, in the embodiment of the present disclosure, when the refrigerating temperature fluctuates up and down during transportation, if the refrigerating temperature can be restored to fluctuate within a preset transportation temperature range within 30 minutes (which may be obtained through big data analysis), the alarm information occurring within the 30 minutes due to the fluctuation of the refrigerating temperature may be regarded as invalid alarm information, and filtered out, that is, no alarm is performed. And if the refrigerating temperature cannot be recovered to fluctuate within the range of the preset transportation temperature area after 30 minutes, the refrigerator is considered to possibly have a fault, at the moment, the alarm information which appears within the 30 minutes and fluctuates up and down due to the refrigerating temperature is regarded as invalid alarm information and filtered, namely no alarm is given, but the alarm information which appears after the 30 minutes and fluctuates up and down due to the refrigerating temperature is regarded as valid alarm information and is reserved and given an alarm.
By the aid of the method and the device, invalid alarms occurring in the transportation process can be filtered out in the time dimension, so that the working efficiency of workers is prevented from being influenced by the invalid alarms occurring in the time dimension.
Further, as an alternative embodiment, the method may further include the following operations.
In response to detecting that the first event has ended, recording a number of times the first event occurred.
It is determined whether the number of times the first event occurred has reached a second preset value.
And if the number of times of occurrence of the first event is determined not to reach the second preset value, not alarming aiming at the first event.
Or, as an optional embodiment, the method may further include alarming for the first event if it is determined that the number of times of occurrence of the first event has reached the second preset value.
Specifically, in the embodiment of the present disclosure, if the first event occurring during transportation is ended when the duration time does not reach the first preset value, and such a phenomenon occurs continuously for a plurality of times, it is considered that a fault occurs in the refrigerator or the temperature sensor, and at this time, it is considered as an effective alarm, and there is no need to filter, and a normal alarm is required.
For example, in the embodiment of the present disclosure, when the refrigerating temperature fluctuates during transportation, although the first event ends within 30 minutes, within 30 minutes or within 20 minutes, the first event continuously occurs multiple times (for example, 3 times or more), and it is considered that a fault occurs in the refrigerator or the temperature sensor, and at this time, it is considered that an effective alarm is generated, and filtering is not required, and a normal alarm is required.
Through the embodiment of the disclosure, invalid alarms occurring in the transportation process can be filtered from the time dimension and the statistics frequency dimension, so that the working efficiency of workers is prevented from being influenced by the invalid alarms occurring in the period, and meanwhile, the problem that the temperature of the workers cannot be checked in time due to the fact that the valid alarms are blocked can be avoided, and the quality of goods is influenced.
By the embodiment of the disclosure, in the transportation process, the duration of the continuous abnormity and the occurrence frequency of the continuous abnormity can be used as parameters to judge whether to execute the alarm or filter the alarm information.
In one embodiment of the present disclosure, after the temperature sensor returns the temperature information, the temperature is recorded and whether the temperature is an abnormal temperature is determined. If the temperature is abnormal, the alarm is not informed at the moment, and the time record of the abnormal temperature is stored. After saving, a processing event is established, which can determine the duration of the abnormal temperature every 1 minute. And if the duration of the abnormal temperature reaches 30 minutes, alarming and informing. If the temperature sensor returns the information that the temperature is normal within 30 minutes, the event is relieved, and meanwhile, an alarm notice is not sent. Invalid alarm messages can thus be filtered. Meanwhile, in the embodiment of the present disclosure, the number statistics may also be increased. After the temperature sensor returns the abnormal temperature information, the event continuously receives the abnormal temperature information for a plurality of times (for example, more than 3 times), and the alarm is directly notified instead of the logic judgment for 30 minutes. Therefore, invalid alarm information with fluctuating temperature can be filtered, and the situation that valid alarm information is put away can be avoided.
As an alternative embodiment, operation S401 may include the following operations.
A start time of a last executed pre-cooling operation recorded for the refrigerated space is determined.
And determining the finish time of the precooling operation.
The current time information is acquired.
Based on the time information, it is determined whether the current time is between the start time and the end time to determine whether the refrigerated space is currently in the pre-cooling phase.
In addition, in the embodiment of the present disclosure, if the starting time of the precooling operation is not recorded, it may also be determined whether the vehicle has an ongoing waybill task through the waybill state. If so, the time of departure in the order loading state can be used as the starting time of vehicle precooling.
It should be noted that, in the embodiment of the present disclosure, when performing actual business operations, an association relationship may be established between the waybill and the vehicle. The first of these associations may be the sealing status of the manifest (for which the manifest has completed loading). After the freight note enters a vehicle sealing state, the freight note can be bound with the vehicle.
Specifically, in the embodiment of the present disclosure, when the vehicle receives the first waybill-sealing state, the time point of the sealing may be recorded, and the refrigerator is turned on to start cooling the vehicle. In the refrigerating process, the temperature sensor is ensured to measure and calculate the temperature of the vehicle in the whole process. The precooling duration (precooling time for short) can be predicted through a data model created based on big data.
Further, as an optional embodiment, determining the ending time of completing the pre-cooling operation may include: and determining the finish time of the precooling operation based on the vehicle type and the refrigerator power of the vehicle, wherein the refrigerator power is the power of the refrigerator for refrigerating the refrigerated space when the refrigerator normally works.
Specifically, the pre-cooling time (T) may be determined based on the model of the vehicle and the refrigerator power, at the start time (T) based on the pre-cooling operation0) And calculating an end time (T) of the precooling operation1). E.g. T1＝T0+t。
As an alternative embodiment, determining the end time for completing the pre-cooling operation may include the following operations based on the vehicle type and the refrigerator power of the vehicle.
And determining a corresponding data model by using the model of the vehicle and the refrigerating machine power as basic information.
And taking the minimum temperature value and the maximum temperature value in the preset temperature zone range as input values of the data model, calculating corresponding output values and taking the output values as the precooling time of the precooling operation.
The end time is determined by calculating the sum of the start time and the pre-cooling time.
In particular, in the process, the continuous precooling time required by the precooling process of the cold chain transport vehicle can be predicted. The method comprises the following steps: determining a vehicle model (M) of the cold chain transport vehicle and the refrigerating power (W) of a refrigerator arranged on the cold chain transport vehicle, and determining a data model required for calculating the continuous precooling time required in the precooling process of the cold chain transport vehicle by taking the vehicle model information and the refrigerating power as basic information; and determining a preset temperature area range set for the current transportation task of the cold chain transport vehicle, taking the maximum temperature value and the minimum temperature value in the preset temperature area range as input values of the data model, wherein the output value is the continuous precooling time required by the cold chain transport vehicle in the precooling process.
It should be noted that, in the embodiment of the present disclosure, the data model may be trained according to big data. Specifically, the following operations may be performed in the process of training the data model: (1) the temperature (Q) collected by the temperature sensor on the vehicle with the same vehicle type and refrigeration power as the cold chain transport vehicle1) (with time information) and a preconfigured temperature range (Q)2i) Calculating the precooling time X of the vehicle as a reference value; (2) and (3) repeating the operation (1) for multiple times to obtain multiple precooling times X, calculating the average value of the multiple precooling times X, and taking the average value as the final precooling time of the vehicle.
Wherein each precooling time X ═ Q ((Q))2min-Q1) Whether or not > 0) … ((Q)2i-Q1) Whether or not > 0) … … ((Q)2max-Q1) Whether or not > 0)
Wherein Q is2minIndicating the lowest temperature, Q, in a pre-configured temperature zone2maxIndicating pre-provisioningThe highest temperature in the warm zone. If the temperature returned by the temperature sensor every time is less than the temperature of the temperature zone configured in advance, precooling is finished. At the moment, the pre-cooling time calculated by the big data is the pre-cooling duration of the combination of the vehicle type and the refrigerator power. With this time range, invalid alarms for pre-cooling periods may be filtered. Specifically, when the abnormal temperature data returned by the temperature sensor is data occurring after the precooling start time and before the precooling end time, the abnormal temperature data is regarded as invalid alarm information. Therefore, invalid alarms in the precooling link can be successfully filtered.
As an alternative embodiment, the method may further include the following operations.
In response to determining that the refrigerated space is not currently in the pre-cool phase, it is determined whether goods are currently within the refrigerated space.
And if the goods are determined not to be currently in the refrigerating space, no alarm is given for the first event.
It should be noted that experiments show that, according to the embodiment of the present disclosure, 70% of invalid alarms can be shielded, and the work efficiency of the worker is greatly improved.
