[0053] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0054] An embodiment of the present invention provides a method for analyzing the working condition of a mixer truck, such as Figure 1As shown, the working condition analysis method includes the following steps:

[0055] Step S101: obtaining the distance between the initial working position of the mixer truck and the actual position of the mixer truck;

[0056] Step S102: obtaining the operation information of the mixer truck;

[0057] Step S103: determining the operating condition of the mixer truck based on the distance and operation information;

[0058] Step S104: determining whether the order of the operating conditions sequentially experienced by the mixer truck satisfies a predetermined order according to the operating conditions;

[0059] Step S105: When the determined sequence satisfies the predetermined sequence, it is determined that the mixer truck has undergone a cycle operation.

[0060] The mixer truck in this embodiment has an on-board terminal and an Internet of Things platform. The Internet of Things platform includes a processor. The on-board terminal and the Internet of Things platform are communicatively connected. The on-board terminal will transmit the recorded data (such as GPS data, driving speed, engine speed, mixing drum speed, total fuel consumption, and data timestamp, etc.) to the Internet of Things platform. The processor in the Internet of Things platform will then process the above data to achieve the purpose of mixer truck customer operating status capability assessment or industry data analysis.

[0061] In this embodiment, the initial working position of the mixer truck is the mixing station. That is, the mixing station is the starting point of the mixer truck's cycle work and is also the location where the mixer truck appears most frequently in its daily transportation route. Moreover, the mixing station where the mixer truck works is fixed for a period of time. Therefore, based on the above characteristics, the processor can analyze the GPS data to obtain the geographical location of the mixing station. Specifically, obtaining the initial working position of the mixer truck includes the following steps:

[0062] Step S201: Obtain the time interval between two valid ignition data of the mixer truck, and determine whether the time interval is greater than a preset time interval.

[0063] It can be understood that the ignition data in this embodiment can be obtained from the ACC-ON data of the mixer truck, and the above-mentioned time interval ΔH1 can be determined based on the data timestamps of two valid ACC-ON data (i.e., the data timestamp of the current ACC-ON data and the data timestamp of the previous ACC-ON data). After obtaining the above-mentioned time interval ΔH1, the processor compares it with the preset time interval t1 pre-stored in the processor, and performs subsequent operations based on the comparison results.

[0064] Step S202: When the time interval is greater than the preset time interval, the GPS position of the mixer truck for ignition is obtained.

[0065] That is, when the time interval ΔH1 is greater than the preset time interval t1, the processor marks the GPS position corresponding to the valid ignition data of the mixer truck in step S201.

[0066] Step S203: Obtain the number of times the mixer truck appears at the GPS location within a preset continuous time period, and determine whether the number exceeds the preset number.

[0067] When step S202 is satisfied, the processor further obtains the number n of times the mixer truck appears at the same GPS location within a continuous preset time period (such as one day, one week, one month, one quarter or one year, etc.), and after obtaining the above number n, compares it with the preset number N in the processor, and performs subsequent operations based on the comparison results.

[0068] Step S204: when the number of times exceeds the preset number of times, obtaining the position deviation between two adjacent GPS positions.

[0069] That is, when the number n in step S203 exceeds the preset number N, the processor marks the current GPS position that meets the judgment condition of step S203 and the GPS position that met the judgment condition of step S203 last time, and then obtains the position deviation ΔS1 between the two GPS positions.

[0070] Step S205: Determine whether the position deviation is within a preset range.

[0071] After obtaining the position deviation ΔS1, the processor compares it with the preset range S1 in the processor and performs subsequent operations based on the comparison result.

[0072] Step S206: When the position deviation is within the preset range, obtain the average value of all GPS positions that meet the requirements of steps S201, S203 and S205.

[0073] It can be understood that if the position deviation is not within the preset range, it means that the GPS position obtained in steps S202-S204 is not within the location range of the mixing station, and it needs to be divided into a geographical location outside the mixing station (that is, there is no need to eliminate data that does not meet the above conditions).

[0074] Step S207: Determine the initial working position of the mixer truck according to the average value.

[0075] That is, after obtaining all GPS positions that meet step S201, step S203, and step S205, the average value of all the GPS positions is calculated, and the average value is the initial working position of the mixer truck (i.e., the location of the mixing station). After obtaining the initial working position of the mixer truck, the processor determines the actual position of the mixer truck according to the real-time GPS data of the mixer truck, and then determines the distance (the distance is the distance between the mixing station and the mixer truck) according to the absolute value of the difference between the actual position and the initial working position; based on the engine speed, mixing drum speed and other data uploaded by the vehicle terminal, the processor can obtain the operation information of the mixer truck; a cycle working condition of the mixer truck (the cycle working condition in this embodiment refers to a complete transport working cycle experienced by the mixer truck) includes multiple different operating conditions arranged in sequence, so the processor first determines a certain operating condition of the mixer truck in combination with the distance and operating information, and then determines whether the arrangement order between the multiple different operating conditions meets the preset order. If it meets, it is determined that the mixer truck has experienced a complete cycle working condition; if not, the mixer truck has not experienced a complete cycle working condition. The operating condition analysis method for a mixer truck provided in this embodiment can extract effective operating condition data from the massive data uploaded by the mixer truck's onboard terminal for analysis, so as to quickly and effectively determine the cyclic operating conditions experienced by the mixer truck. Compared with the simple sampling analysis method used in the prior art, this method can also eliminate errors caused by small sample size, and is simple, efficient and reliable.

[0076] In one embodiment of the present invention, the sequence of operating conditions includes:

[0077] The mixer truck goes through the conditions of waiting for receiving materials, fully loaded transportation, unloading at the construction site and returning empty in sequence.

[0078] In this embodiment, the mixer truck's operating task is to transport concrete. A mixer truck cycle includes four operating conditions: a material receiving waiting condition, a fully loaded transport condition, a construction site unloading condition, and an empty return condition. The material receiving waiting condition refers to the process of the mixer truck waiting in line and receiving materials at the mixing station; the fully loaded transport condition refers to the process of the mixer truck transporting concrete to the construction site after receiving materials at the mixing station; the construction site unloading condition refers to the process of the mixer truck unloading concrete to the construction site; and the empty return condition refers to the process of the mixer truck returning to the mixing station after unloading concrete. Furthermore, the cycle conditions in this embodiment may also include other operating conditions based on the actual operating task of the mixer truck, and the order of the different operating conditions may also be adjusted accordingly based on actual conditions.

[0079] In one embodiment of the present invention, the operating information includes engine speed and / or mixer drum rotation direction.

[0080] Since the data uploaded by the vehicle terminal includes the engine speed and the mixer drum speed, and the mixer drum speed has a magnitude and a direction, the mixer drum direction can be determined according to the direction of the mixer drum speed.

[0081] In one embodiment of the present invention, determining the operating condition of the mixer truck based on the distance and operation information includes the following steps:

[0082] Step S301: Determine whether the distance is less than a first preset value and whether the engine speed is greater than a first preset speed;

[0083] Step S302: When it is determined that the distance is less than the first preset value and the engine speed is greater than the first preset speed, it is determined that the mixer truck is in a material receiving waiting state.

[0084] The material receiving and waiting condition is the first operating condition in the mixer truck's cycle condition. When determining this condition, the processor first determines whether the mixer truck is in the mixing station based on the distance ΔS2 (ΔS2 is the distance between the initial working position of the mixer truck in the material receiving and waiting condition and the actual position of the mixer truck). That is, it first determines whether the distance ΔS2 is less than the first preset value K1. If the distance ΔS2 is less than the first preset value K1, it means that the mixer truck is in the mixing station; if the distance ΔS2 is greater than or equal to the first preset value K1, it means that the mixer truck is not in the mixing station. Specifically, the first preset value K1 refers to the preset radius of the mixing station site. The researchers will investigate the site radius of multiple actual mixing stations in advance, and then set the first preset value K1 based on the above research results and pre-store it in the processor.

[0085] The processor performs a subsequent determination only when the distance ΔS2 is less than the first preset value K1. Specifically, only when the distance ΔS2 is less than the first preset value K1 does the processor further determine whether the engine speed is greater than the first preset speed. If the engine speed is greater than the first preset speed, the mixer truck is determined to be in a material receiving and waiting state. If the engine speed is less than or equal to the first preset speed, the mixer truck is determined not to be in a material receiving and waiting state. Furthermore, in this embodiment, the first preset speed is set based on the engine's idle speed and is pre-stored in the processor.

[0086] In one embodiment of the present invention, determining the operating condition of the mixer truck based on the distance and operation information includes the following steps:

[0087] Step S401: determining whether the distance is greater than a first preset value, whether the engine speed is greater than a second preset speed, and whether the mixer drum is rotating in a forward direction;

[0088] Step S402: When it is determined that the distance is greater than a first preset value, the engine speed is greater than a second preset speed, and the mixer drum is turning in a forward direction, it is determined that the mixer truck is in a fully loaded transport condition.

[0089] The fully loaded transport condition is the second operating condition in the mixer truck's cycle. This condition is determined only after the material receiving and waiting condition has been determined. When determining the fully loaded transport condition, the processor first determines whether the mixer truck is within the mixing station based on the distance ΔS3 (ΔS3 is the distance between the mixer truck's initial operating position and its actual position under the fully loaded transport condition). That is, it first determines whether the distance ΔS3 is greater than a first preset value K1. If the distance ΔS3 is greater than the first preset value K1, it indicates that the mixer truck is far away from the mixing station. If the distance ΔS3 is less than or equal to the first preset value K1, it indicates that the mixer truck is still within the mixing station.

[0090] The processor makes a subsequent determination when the distance ΔS3 is greater than the first preset value K1. Specifically, only when the distance ΔS3 is greater than the first preset value K1 does the processor further determine whether the engine speed is greater than a second preset speed and whether the mixer drum is rotating in the forward direction. If the engine speed is greater than the second preset speed and the mixer drum is rotating in the forward direction, the mixer truck is determined to be in a fully loaded transport condition. If the engine speed is less than or equal to the second preset speed and / or the mixer drum is not rotating in the forward direction, the mixer truck is determined not to be in a fully loaded transport condition. Furthermore, in this embodiment, the second preset speed is set based on the engine speed of the fully loaded mixer truck and is pre-stored in the processor.

[0091] In one embodiment of the present invention, determining the operating condition of the mixer truck based on the distance and operation information includes the following steps:

[0092] Step S501: determining whether the distance is greater than a first preset value and whether the mixing drum is rotating in the reverse direction;

[0093] Step S502: When it is determined that the distance is greater than the first preset value and the mixer drum is turning in the reverse direction, it is determined that the mixer truck is in the construction site unloading condition.

[0094] The construction site unloading condition is the third operating condition in the mixer truck's cycle condition. This condition is determined only after the full-load transport condition is determined. When determining the construction site unloading condition, the processor determines whether the distance ΔS4 (ΔS4 is the distance between the mixer truck's initial working position and its actual position under the construction site unloading condition) is greater than a first preset value K1, and whether the mixer drum is rotating in the opposite direction. If the distance ΔS4 is greater than the first preset value K1 and the mixer drum is rotating in the opposite direction, the mixer truck is determined to be in the construction site unloading condition at this time; if the distance ΔS4 is less than or equal to the first preset value K1 and the mixer drum is not rotating in the opposite direction, the mixer truck is determined not to be in the construction site unloading condition at this time.

[0095] In one embodiment of the present invention, determining the operating condition of the mixer truck based on the distance and operation information includes the following steps:

[0096] Step S601: determining whether the mixer truck is gradually approaching the initial working position based on the initial working position and the actual position;

[0097] Step S602: When it is determined that the mixer truck is gradually approaching the initial working position, determining whether the distance is less than a first preset value and whether the engine speed is greater than a third preset speed;

[0098] Step S603: When it is determined that the distance is less than the first preset value and the engine speed is greater than the third preset speed, it is determined that the mixer truck is in an empty return condition.

[0099] The no-load return condition is the fourth operating condition in the mixer truck's cycle. This condition is determined only after the construction site unloading condition is determined. When determining the no-load return condition, the processor can determine whether the mixer truck is gradually approaching the mixer truck based on the acquired mixing station location and the mixer truck's real-time GPS location. That is, when the distance between the mixer truck's real-time GPS location and the mixer truck's location gradually decreases, the mixer truck is determined to be gradually approaching the initial working position. After determining that the mixer truck is gradually approaching the initial working position, the processor further determines whether the distance ΔS5 (ΔS5 is the distance between the mixer truck's initial working position and the mixer truck's actual position in the no-load return condition) is less than a first preset value K1, and whether the engine speed is greater than a third preset speed. If the distance ΔS5 is less than the first preset value K1 and the engine speed is greater than the third preset speed, the mixer truck is determined to be in the no-load return condition. If the distance ΔS5 is greater than or equal to the first preset value K1, and / or the engine speed is not greater than the third preset speed, the mixer truck is determined to be not in the no-load return condition. Furthermore, the third preset speed in this embodiment is set according to the speed of the engine when the mixer truck is idling and is pre-stored in the processor.

[0100] In one embodiment of the present invention, the operating condition analysis method further includes: obtaining the single average fuel consumption and the total average fuel consumption of the mixer truck under a certain operating condition to optimize the configuration of the mixer truck.

[0101] After determining each operating condition in the cycle, the processor combines the single average fuel consumption and total average fuel consumption of the mixer truck under each operating condition to analyze the fuel consumption performance of mixer trucks with different configurations (such as different rear axle speed ratios, different engine rated powers, different gear speed ratios or different mixing drum volumes, etc.) under different operating conditions, and then distinguishes the fuel tank performance under the influence of factors such as different rear axle speed ratios, different engine rated powers, different gear speed ratios or different mixing drum volumes. Based on the above fuel tank performance, the various parameters of the mixer trucks in different areas are reasonably designed (the various parameters include at least one of the rear axle speed ratio, engine rated power, gear speed ratio and mixing drum volume), thereby optimizing the configuration of the mixer truck, improving the product performance of the mixer truck, and making the mixer truck more suitable for usage scenarios in different areas.

[0102] In one embodiment of the present invention, obtaining the single average fuel consumption and the total average fuel consumption of a mixer truck under a certain operating condition includes the following steps:

[0103] Step S701: When it is determined that the distance is less than a first preset value and the engine speed is greater than the first preset speed, obtaining a first operating time and a first fuel consumption of the engine;

[0104] Step S702: Based on the first working time and the first fuel consumption, obtain the single average fuel consumption and the total average fuel consumption of the mixer truck in the material receiving and waiting condition.

[0105] In this embodiment, the processor obtains the average fuel consumption of the mixer truck in the material receiving and waiting condition according to the following formula:

[0106]

[0107] Among them, A1 is the average fuel consumption of the mixer truck in the condition of waiting for receiving materials, in L / h; ΔL1 is the first fuel consumption, in L, which is the fuel consumption of the mixer truck when the distance ΔS2 is less than the first preset value K1; ΔH2 is the first working time of the engine, in h, which is the working time of the engine when the distance ΔS2 is less than the first preset value K1.

[0108] The processor obtains the total average fuel consumption of the mixer truck in the material receiving and waiting condition according to the following formula:

[0109]

[0110] Among them, B1 is the total average fuel consumption of the mixer truck in the condition of waiting for receiving materials, in L / h.

[0111] In one embodiment of the present invention, obtaining the single average fuel consumption and the total average fuel consumption of a mixer truck under a certain operating condition includes the following steps:

[0112] Step S801: When it is determined that the distance is greater than a first preset value, the engine speed is greater than a second preset speed, and the mixer drum is rotating in a forward direction, obtaining a second fuel consumption of the engine and a first mileage of the mixer truck;

[0113] Step S802: obtaining the single average fuel consumption and the total average fuel consumption of the mixer truck under the fully loaded transport condition based on the second fuel consumption and the first driving mileage.

[0114] In this embodiment, the processor obtains the average fuel consumption of a single trip of the mixer truck under full-load transport conditions according to the following formula:

[0115]

[0116] Among them, A2 is the average fuel consumption of the mixer truck under full-load transportation conditions, in L / Km; ΔL2 is the second fuel consumption, in L, which is the fuel consumption of the mixer truck under full-load transportation conditions. The value of ΔL2 is the difference between the fuel consumption of the mixer truck when unloading at the construction site and the fuel consumption of the mixer truck when at the mixing station; ΔS6 is the mileage of the mixer truck under full-load transportation, in Km. The value of ΔS6 is the difference between the odometer reading of the mixer truck when unloading at the construction site and the odometer reading of the mixer truck when at the mixing station.

[0117] The processor obtains the total average fuel consumption of the mixer truck in the material receiving and waiting condition according to the following formula:

[0118]

[0119] Among them, B2 is the total average fuel consumption of the mixer truck in the condition of waiting for receiving materials, and the unit is L / Km.

[0120] In one embodiment of the present invention, obtaining the single average fuel consumption and the total average fuel consumption of a mixer truck under a certain operating condition includes the following steps:

[0121] Step S901: when it is determined that the distance is greater than a first preset value and the mixer drum is rotating in the reverse direction, obtaining a second operating time and a third fuel consumption of the engine;

[0122] Step S902: Based on the second working time and the third fuel consumption, obtain the single average fuel consumption and the total average fuel consumption of the mixer truck under the unloading condition at the construction site.

[0123] In this embodiment, the processor obtains the average fuel consumption of a mixer truck under the unloading condition at the construction site according to the following formula:

[0124]

[0125] Among them, A3 is the average single fuel consumption of the mixer truck under the unloading condition on the construction site, measured in L / h; ΔL3 is the third fuel consumption, measured in L, and the third fuel consumption is the fuel consumption of the mixer truck under the unloading condition on the construction site; ΔH3 is the second working time of the engine, measured in h, and the second working time is the working time of the mixer truck engine under the unloading condition on the construction site.

[0126] The processor obtains the total average fuel consumption of the mixer truck under the unloading condition at the construction site according to the following formula:

[0127]

[0128] Among them, B3 is the total average fuel consumption of the mixer truck under the unloading condition at the construction site, in L / h.
