Description
Technical Field
[0001] The present invention belongs to the technical field of cold chain transportation monitoring, and specifically relates to a comprehensive monitoring terminal and monitoring method for a cold chain transportation box. Background Art
[0002] A patent with the publication number CN113706071A discloses a monitoring method, system, terminal and storage medium for a cold chain transportation box, which relates to the field of cold chain transportation. The monitoring method for the cold chain transportation box includes: obtaining parameter information of the transportation box, where the parameter information includes the real-time temperature value inside the transportation box and the number of the transportation box; judging whether the real-time temperature value is higher than a preset temperature value according to the parameter information; if the judgment is yes, forming an alarm message; obtaining vehicle information, where the vehicle information includes the vehicle driving route and the driver terminal, and the vehicle driving route consists of several service stations and sub-driving routes between the service stations; sending the service station location and the alarm message to the driver terminal according to the vehicle driving route. This application can facilitate the driver to monitor the temperature inside the transportation box and take remedial measures in time to reduce the probability of food spoilage.
[0003] However, for the cold chain transportation box, the above patent mainly focuses on the temperature situation during its transportation process to determine whether there are problems during the transportation of the transportation box. However, when it comes to the end of transportation or transfer in the middle, first, the cold chain transportation box needs to be unloaded. At this time, the cold chain transportation box is separated from the low-temperature environment of the logistics vehicle, and under the influence of the external environment, some temperature fluctuations may occur, thereby increasing the risk of damage to the corresponding cold chain products. At the same time, if it is placed in the unloading area for too long and not transferred to the storage location in time, it will also affect the quality of the cold chain products; to solve this problem, a solution is proposed now. Summary of the Invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a comprehensive monitoring method for a cold chain transportation box;
[0005] The method specifically includes the following steps:
[0006] Step 1: Mark the cold chain transportation box as the target object, and then obtain information. Obtain the temperature inside the target object and mark it as the internal temperature data, and obtain the temperature of the environment where the target object is located and mark it as the external temperature data. The internal temperature data and the external temperature data form the temperature information.
[0007] Step 2: Then analyze the temperature information, determine the state of the target object at this time according to the temperature information, and obtain the temperature growth situation of the external temperature data. When the temperature of the external temperature data is detected to rise by more than X1 compared to the previous node at any node, an external increase signal is generated.
[0008] After subtracting the internal temperature data from the external temperature data, the obtained value is marked as the internal-external differential temperature. Similarly, if the internal-external differential temperature detected at any node shows a temperature increase exceeding X1 compared to the previous node, a differential increase signal is generated;
[0009] When both the external increase signal and the differential increase signal are generated simultaneously, the state of the target object at this time is marked as State One.
[0010] Furthermore, the specific method for obtaining temperature information in Step One is as follows:
[0011] An internal temperature acquisition unit is set inside the target object to obtain the real-time temperature inside the cold chain transportation box, which is marked as internal temperature data;
[0012] An external temperature acquisition unit is set on the outer wall of the target object to obtain the real-time temperature of the environment where the cold chain transportation box is located, which is marked as external temperature data;
[0013] The internal temperature data and the external temperature data are obtained and marked as temperature information.
[0014] Furthermore, the specific determination method for determining the state in Step Two is as follows:
[0015] First, the external temperature data and the internal temperature data in the temperature information are obtained. After subtracting the internal temperature data from the external temperature data, the obtained value is marked as the internal-external differential temperature;
[0016] The external temperature data and the internal-external differential temperature are acquired every T1 time interval. T1 is a preset value, and they are marked as Wi and Ci in sequence, where i = 1,..., n. Here, Wn represents the external temperature data obtained at the latest moment, and Cn represents the internal-external differential temperature obtained at the latest moment;
[0017] After that, the real external increase value Zwi and the real differential increase value Zci are obtained. The specific acquisition formula is as follows:
[0018]
[0019] When it is detected that Zwi exceeds X1 (X1 is a preset value), an external increase signal is generated. At the same time, it will be detected whether the increase value of the corresponding Zci at this time exceeds X1. If it does, a differential increase signal is generated;
[0020] After that, a comprehensive determination is made based on the generated external increase signal and differential increase signal. The specific determination method is as follows:
[0021] When both the external increase signal and the differential increase signal are generated simultaneously, the state at this time is marked as State One;
[0022] When only the external increase signal or the differential increase signal is generated, the state at this time is marked as an alarm signal. At this time, the target object corresponding to the generated alarm signal is automatically acquired and marked as the warning object.
[0023] Further, after step two is completed, the following steps need to be carried out:
[0024] Step 1): Transmit the signals generated by all target objects to the cloud processing end, and perform signal operation and analysis with the help of the cloud. The specific method of signal operation and analysis is as follows:
[0025] First, obtain all target objects in the corresponding freight vehicle. When any target object generates state one, transmit it to the corresponding cloud processing end. The cloud processing end numbers them in sequence according to the transmission order of the received target objects, and marks the serial number of the corresponding target object as the target sequence value;
[0026] Step 2): Obtain the sequence value of the target object according to numerical analysis, and then drive the alarm in the target object to emit light and beep in sequence according to the order of the sequence value. The specific method is as follows:
[0027] First, obtain the target object with the smallest sequence value, drive its alarm to emit light and beep, and automatically stop when it is detected that the actual external increment Zwi starts to be negative;
[0028] After that, select target objects in ascending order of the sequence value, and process them in the above steps in sequence until the alarms of all target objects stop beeping.
[0029] Further, the specific method of numerical analysis is as follows:
[0030] Assign the value corresponding to the target sequence value of the target object to the sequence value.
[0031] Further, the specific method of numerical analysis is as follows:
[0032] First, obtain the target sequence value of the target object;
[0033] After that, obtain the internal temperature data of all target objects, and synchronously obtain the upper limit storage temperature of the items stored in the corresponding target object. The upper limit storage temperature refers to the highest temperature allowed for the storage of the corresponding items in the corresponding target object;
[0034] Subtract the internal temperature data from the upper limit storage temperature, and then mark the obtained value as the pressure difference;
[0035] After that, calculate the sequence value using the formula. The specific method of obtaining the sequence value is as follows:
[0036] Sequence value = 0.42 * pressure difference + 0.58 * target sequence value;
[0037] In the formula, both 0.42 and 0.58 are preset values.
[0038] A comprehensive monitoring terminal for a cold chain transport box, which realizes the monitoring of the cold chain transport box by using the foregoing monitoring method.
[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0040] In the present invention, the cold chain transportation box is marked as the target object, and then information is obtained. The temperature inside the target object is obtained and marked as the internal temperature data, and the temperature of the environment where the target object is located is obtained and marked as the external temperature data. The internal temperature data and the external temperature data form the temperature information;
[0041] After that, the temperature information is analyzed, and the state of the target object at this time is determined according to the temperature information, which are state one and warning signal respectively. According to state one, the unloading state of the cold chain transportation box is distinguished, and different monitoring is started, and reasonable arrangements are made for the unloading waiting and transfer sequence, so as to realize better monitoring of the quality of the products transported by the cold chain transportation box; the present invention is simple and effective, and easy to use.

[0044] Next, the technical solutions of the present invention will be described clearly and completely in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0045] As Figure 1 - Figure 2 shown, the present application provides a comprehensive monitoring method for a cold chain transportation box;
[0046] As Embodiment 1 of the present invention, the method specifically includes the following steps:
[0047] Step 1: For the convenience of description, first, the cold chain transportation box is marked as the target object, which will be unified hereinafter, and then information is obtained. The specific method is as follows:
[0048] An internal temperature acquisition unit is arranged inside the target object to acquire the real-time temperature inside the cold chain transportation box and mark it as the internal temperature data;
[0049] An external temperature acquisition unit is arranged on the outer wall of the target object to acquire the real-time temperature of the environment where the cold chain transportation box is located and mark it as the external temperature data;
[0050] The internal temperature data and the external temperature data are obtained and marked as the temperature information;
[0051] Step 2: Then analyze the temperature information and determine the state of the target object at this time. The specific determination method is as follows:
[0052] First, obtain the external temperature data and internal temperature data in the temperature information, subtract the internal temperature data from the external temperature data, and mark the obtained value as the internal and external differential temperature;
[0053] Obtain the external temperature data and the internal and external differential temperature every T1 time. T1 is a preset value, and they are marked as Wi and Ci in sequence, where i = 1,..., n. Here, Wn represents the external temperature data obtained at the latest moment, and Cn represents the internal and external differential temperature obtained at the latest moment;
[0054] Then obtain the actual external increase value Zwi and the actual differential increase value Zci. The specific acquisition formula is as follows:
[0055]
[0056] When it is detected that Zwi exceeds X1 (X1 is a preset value), an external increase signal is generated. At the same time, it will be detected whether the increase value of the corresponding Zci at this time exceeds X1. If it exceeds X1, a differential increase signal is generated;
[0057] Then make a comprehensive determination according to the generated external increase signal and differential increase signal. The specific determination method is as follows:
[0058] When both the external increase signal and the differential increase signal are generated at the same time, mark the state at this time as State One;
[0059] When only the external increase signal or the differential increase signal is generated, mark the state at this time as an alarm signal. At this time, automatically obtain the target object corresponding to the generated alarm signal and mark it as the warning object;
[0060] Certainly, as Embodiment 2 of the present application, it is implemented on the basis of Embodiment 1. After the processing of Step 2 in Embodiment 1 is completed, the following steps can also be carried out:
[0061] Step 1): Then, with the help of the freight vehicle where the target object is located, establish a signal transmission channel between the target object and the cloud processing end. This is a prior art, so no specific description will be given here. Transmit all the signals generated by the target objects to the cloud processing end, and perform signal operation and analysis with the help of the cloud to obtain the transfer reminder information. The specific method of signal operation and analysis is as follows:
[0062] First, obtain all the target objects in the corresponding freight vehicle. When any target object generates State One, transmit it to the corresponding cloud processing end. The cloud processing end numbers them in sequence according to the received transmission order of the target objects, and marks the serial number of the corresponding target object as the target sequence value;
[0063] Step 2): Mark the target sequence value as the sequence value corresponding to the target object according to the value of the target sequence value. Then, in the order of the sequence values, drive the sirens in the target objects to emit light and beep one by one. The specific method is as follows:
[0064] First, obtain the target object with the smallest sequence value, drive its siren to emit light and beep, and automatically stop when it is detected that the actual external increase value Zwi starts to be negative;
[0065] After that, select the target objects in ascending order of the sequence values, and process them in the above steps one by one until the sirens of all the target objects stop beeping.
[0066] Of course, as Embodiment 3 of the present application, this embodiment is implemented on the basis of Embodiment 2. The difference from Embodiment 2 is that the processing method in Step 2) is different. The specific method in this embodiment is as follows:
[0067] Step 2): First, obtain the target sequence value of the target object;
[0068] After that, obtain the internal temperature data of all the target objects, and synchronously obtain the upper limit storage temperature of the items stored in the corresponding target object. The upper limit storage temperature refers to the highest temperature allowed for the storage of the corresponding items in the corresponding target object;
[0069] Subtract the internal temperature data from the upper limit storage temperature, and then mark the obtained value as the pressure difference;
[0070] After that, calculate the sequence value using the formula. The specific method for obtaining the sequence value is as follows:
[0071] Sequence value = 0.42 * pressure difference + 0.58 * target sequence value;
[0072] In the formula, both 0.42 and 0.58 are preset values;
[0073] First, obtain the target object with the smallest sequence value, drive its siren to emit light and beep, and automatically stop when it is detected that the actual external increase value Zwi starts to be negative;
[0074] After that, select the target objects in ascending order of the sequence values, and process them in the above steps one by one until the sirens of all the target objects stop beeping.
[0075] Of course, as Embodiment 4 of the present application, the difference between this embodiment and Embodiment 3 is that when finally calculating the sequence value in Step 2), the pressure difference is replaced by the expected melting time. The expected melting time is to first observe the T2 time (T2 is a preset value), then calculate the temperature increase value per unit time of the corresponding target object, and then calculate how long it takes for the temperature corresponding to the pressure difference value to rise. Mark this time as the expected melting time; the rest of the solutions are the same as those in Embodiment 3.
[0076] As the fifth embodiment of the present application, the solution of this embodiment is to implement by integrating Embodiments 1 to 4. When there are parallel manners in the embodiments, one is randomly selected and the other is discarded.
[0077] A comprehensive monitoring terminal for a cold chain transportation box, and the monitoring terminal uses the foregoing comprehensive monitoring method to implement comprehensive monitoring of the cold chain transportation box.
[0078] Some of the data in the above formula are calculated by removing the dimension and taking its numerical value. The formula is a formula that is closest to the actual situation obtained through software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by those skilled in the art according to the actual situation or obtained through simulation of a large amount of data.
[0079] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
