Description

Technical Field

[0001] The invention belongs to the field of motor vehicle environmental protection information service, and specifically relates to a diesel vehicle exhaust treatment liquid filling service system and application thereof. Background Art

[0002] As diesel vehicle exhaust emission regulations become increasingly stringent, the requirements for diesel vehicle exhaust treatment are also becoming higher and higher. A common method is to use diesel vehicle exhaust treatment fluid to treat diesel vehicle exhaust so that the treated diesel vehicle exhaust can reduce pollution to the environment.

[0003] At present, diesel exhaust treatment fluid is usually diesel exhaust treatment fluid. Many engine manufacturers use selective catalytic reduction (SCR) exhaust treatment technology. The main working principle of SCR is that the urea in the diesel exhaust treatment fluid is decomposed into NH 3 and CO 2 , the generated NH 3 As a reducing agent, it reacts with NOx in the exhaust gas to generate nitrogen and water, effectively reducing the NOx content in the automobile exhaust gas and reducing the air pollution caused by NOx. Diesel exhaust treatment fluid is an important and necessary consumable in SCR technology.

[0004] In order to carry diesel vehicle exhaust treatment fluid, a container for containing diesel vehicle exhaust treatment fluid is provided on the diesel vehicle. In order to replenish the diesel vehicle exhaust treatment fluid in time, a diesel vehicle exhaust treatment fluid filling machine is usually installed at a gas station. When the diesel vehicle exhaust treatment fluid needs to be replenished, the car needs to go to the gas station to use the filling machine to fill the diesel vehicle exhaust treatment fluid.

[0005] Since gas stations are widely distributed, it is currently impossible to obtain the real-time status of the filling machines at each gas station in a timely manner, which is not conducive to the unified management of the diesel exhaust treatment fluid filling machines at each gas station, and the distribution and maintenance costs are very high.

[0006] Moreover, when building a new gas station or adding new filling machines to an existing gas station, the gas station usually decides the model and quantity of the filling machines by itself. Since the gas station staff are not professional designers, it is easy for the installed filling machines to fail to meet the demand, and the filling machines need to be replaced. This not only affects the operation of the gas station, but also greatly increases the construction cost.

[0007] In addition, diesel exhaust treatment fluid suppliers (manufacturers) are also distributed in different places, and the amount of diesel exhaust treatment fluid required to be unloaded at each gas station is also different. Gas stations are generally located next to highways or provincial and national roads. The distance between diesel exhaust treatment fluid suppliers in various places and gas stations is far. When each gas station needs to distribute diesel exhaust treatment fluid, the gas station staff needs to contact the supplier on their own and inform the supplier of the distribution requirements. The supplier will arrange the distribution after receiving the distribution requirements. Due to incomplete information, the supplier contacted by the gas station staff may not be the closest or most suitable supplier for the gas station, and the supplier may not necessarily distribute according to the optimal route when arranging the distribution. All of these lead to low efficiency and increased costs of filling liquid services. Summary of the invention

[0008] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to provide a diesel vehicle exhaust treatment fluid filling service system and its application, so as to obtain the information of each filling machine in real time, and to arrange the most suitable diesel vehicle exhaust treatment fluid supplier to deliver according to the optimal route when the liquid storage volume of the filling machine is insufficient, and to arrange maintenance in time when the filling machine fails, and to provide a suitable plan when a new filling machine is needed, so as to improve the efficiency of the filling service and reduce the cost.

DETAILED DESCRIPTION

[0072] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0073] like Figure 1 As shown, the diesel vehicle exhaust treatment fluid filling service system of the present invention comprises: a cloud server 10 and a maintenance center 20, a filling machine supplier 30, a diesel vehicle exhaust treatment fluid supplier 40, a logistics distribution center 50 and N filling machines 60 respectively connected to the cloud server;

[0074] The cloud server 10 collects status messages of each filling machine, and sends messages to the diesel vehicle exhaust treatment fluid supplier 40, the logistics distribution center 50, and the maintenance center 20 according to the status messages;

[0075] The cloud server sends a filling machine purchase message to the filling machine supplier 30 according to the received filling machine installation request message.

[0076] The diesel vehicle exhaust treatment fluid supplier 40 includes multiple suppliers that can provide diesel vehicle exhaust treatment fluid; the filling machine supplier 30 includes multiple suppliers that can provide filling machines; the logistics distribution center 50 is equipped with various types of transport vehicles and drivers, which can deliver diesel vehicle exhaust treatment fluid from the diesel vehicle exhaust treatment fluid supplier 40 to the filling machine 60; the maintenance center 20 is equipped with various maintenance tools and maintenance personnel, which can repair the filling machine.

[0077] The embodiments of the system of the present invention are as follows:

[0078] [Example 1]

[0079] The filling machine 60 is arranged in each gas station 70, and one or more filling machines 60 are arranged in each gas station 70. Each filling machine 60 is provided with an industrial computer 601 and a wireless communication module 603 and a liquid level meter 602 connected thereto. Figure 3 As shown; each filling machine 60 has a unique filling machine identification, by which the filling machine can be uniquely identified, and the filling machine identification can adopt a string of numbers, a string of characters, a bar code, a two-dimensional code, and other existing codes that can achieve unique identification.

[0080] The liquid level meter 602 is used to detect the height of the liquid level in the chassis of the filling machine, that is, the liquid level value. The industrial computer 601 collects the liquid level value, sales volume and operating parameters of the filling machine at set time intervals, and sends status messages to the cloud server 10 in real time through the wireless communication module 603. The wireless communication module 603 can use a WIFI module, a 4G module, etc. The wireless network includes but is not limited to a wide area network, a metropolitan area network, a local area network, etc.

[0081] The status message includes: filling machine identification, liquid level value, sales volume, and operating parameters. The operating parameters include: voltage, current parameters, filling machine chassis temperature, vulnerable parts status and other parameters related to the filling machine operation. The sales volume is the average daily volume of the treatment liquid sold by the filling machine or the average monthly volume of the treatment liquid sold, etc., which is used to compare with the designed daily or monthly sales volume of the filling machine. The sales volume can be obtained through the cash register module or filling data on the filling machine, which are all detected by existing sensors or corresponding equipment and collected by the industrial computer.

[0082] [Example 2]

[0083] On the basis of the first embodiment, a liquid unloading machine 604 is provided on each filling machine 60, and a 4G Internet of Things module is installed on each liquid unloading machine 604. The liquid unloading machine 604 is an existing product, which is used to input the diesel vehicle exhaust treatment liquid on the transport vehicle into the filling machine, and accurately measure the amount of liquid unloading, so that the amount of diesel vehicle exhaust treatment liquid delivered to the filling machine 60 can be accurately measured. After the liquid unloading machine 604 completes the liquid unloading, it sends a liquid unloading completion message to the cloud server through the 4G Internet of Things module, and the liquid unloading completion message includes the filling machine identification, liquid unloading amount, transport vehicle number, liquid unloading completion time, etc.

[0084] [Example 3]

[0085] On the basis of the second embodiment, a GPS may be provided on each filling machine 60, so that it is convenient for the cloud server to locate the filling machine and also convenient for the transport vehicle to accurately locate the filling machine that needs to be replenished.

[0086] [Example 4]

[0087] like Figure 2As shown, the cloud server is provided with: a filling machine information processing module 101, a liquid replenishment information processing module 102, a distribution information processing module 103, a filling machine installation design module 104, and a filling machine procurement module 105; the filling machine information processing module 101 is connected to the liquid replenishment information processing module 102 and the filling machine installation design module respectively; the liquid replenishment information processing module 102 is connected to the distribution information processing module 103; the filling machine installation design module 104 is connected to the filling machine procurement module 105; the liquid replenishment information processing module 102 is connected to the diesel vehicle exhaust treatment fluid supplier 40; the distribution information processing module 103 is connected to the logistics distribution center 50; the filling machine procurement module 105 is connected to the filling machine supplier 30; the filling information processing module 101 is connected to the maintenance center 20. Among them, the connection with the diesel vehicle exhaust treatment fluid supplier 40, the connection with the logistics distribution center 50, the connection with the filling machine supplier 30, and the connection with the maintenance center 20 can be understood as communication with the supplier, logistics distribution center, maintenance center's management computer or management system.

[0088] The embodiments of the application method of the above system are as follows:

[0089] [Example 5]

[0090] The method comprises:

[0091] The filling machine information processing module 101 receives the status message of each filling machine 60, and determines whether the liquid level value in the status message is less than the set threshold value. If so, the filling machine is replenished with liquid;

[0092] At the same time, the filling machine information processing module 101 determines whether each operating parameter in the status message is abnormal. If so, the filling machine is repaired. The method for determining whether each operating parameter is abnormal can adopt multiple existing methods. For example, a threshold value or a reference value range can be set for each operating parameter. When the operating parameter does not meet the threshold value or the reference value range, it is determined to be abnormal. These are all set according to the normal operating parameters of each filling machine. The existing method can be used for comparison and judgment, which will not be repeated here.

[0093] At the same time, the filling machine information processing module determines whether the sales volume in the status message is greater than the designed sales volume. If so, a sales volume excess message is sent to the filling machine installation design module. The sales volume excess message includes the filling machine identification, sales volume and designed sales volume. Each filling machine has a designed sales volume. If the actual sales volume exceeds the designed sales volume, it can be determined that the filling machine no longer meets the sales requirements, and therefore needs to be replaced with a new filling machine that meets the sales requirements.

[0094] If the filling machine installation design module receives the sales volume exceeding standard message multiple times, the filling machine modification design and installation is performed; for example, a threshold value P of the number of times can be set, and if the number of sales volume exceeding standard messages received exceeds P times, the filling machine modification design and installation is performed;

[0095] If the filling machine installation design module 104 receives a filling machine installation request message, the filling machine design and installation is performed; the filling machine installation request message includes: gas station number, sales data, and floor area.

[0096] [Example 6]

[0097] like Figure 4 The operation of replenishing the filling machine includes:

[0098] (1) The filling machine information processing module 101 sends a refill request message to the refill information processing module 102, wherein the refill request message includes the filling machine identification, model, and refill amount. The refill amount can be obtained based on the filling machine model and the current liquid level value, that is, the capacity of the filling machine can be known based on the model, and the volume minus the liquid level value can be obtained to obtain the volume of the liquid to be replenished, that is, the refill amount.

[0099] (2) After receiving the liquid replenishment request message, the liquid replenishment information processing module 102 searches for the best supplier from the diesel vehicle exhaust treatment liquid suppliers 40 and sends the liquid replenishment request message to the best supplier;

[0100] (3) After receiving the refill request message, the optimal supplier determines whether to provide diesel vehicle exhaust treatment fluid according to its own situation. If yes, the optimal supplier sends a refill request success message to the refill information processing module 102. If no, the optimal supplier sends a refill request failure message to the refill information processing module 102.

[0101] (4) After receiving the successful liquid replenishment request message, the liquid replenishment information processing module 102 sends a waiting delivery message to the filling machine information processing module 101, and sends a delivery request message to the delivery information processing module 103, and then proceeds to step (5); the waiting delivery message includes the name and address of the optimal supplier; the delivery request message includes the filling machine identification, model, liquid replenishment amount, and the address of the optimal supplier;

[0102] After receiving the message of the failure of the replenishment request, the replenishment information processing module 102 searches for the best supplier from other diesel vehicle exhaust treatment fluid suppliers 40 (i.e., suppliers that send the message of the failure of the replenishment request are no longer considered), and then sends the replenishment request message to the best supplier, and then returns to step (3);

[0103] (5) After receiving the delivery request message, the delivery information processing module 103 obtains the address of the filling machine according to the filling machine identifier in the delivery request message, obtains the optimal delivery path according to the address of the filling machine and the address of the optimal supplier, and determines the model of the transport vehicle according to the amount of liquid replenishment, and then sends the delivery message to the logistics distribution center 50. The delivery message includes: the address of the filling machine, the optimal delivery path, and the model of the transport vehicle. The optimal delivery path can be obtained using existing map software such as Amap and Baidu Map.

[0104] (6) After receiving the delivery message, the logistics distribution center 50 arranges a transport vehicle of a corresponding model to deliver the diesel vehicle exhaust treatment liquid from the optimal supplier to the corresponding gas station according to the optimal delivery path, and then the logistics distribution center 50 sends a delivery completion message to the delivery information processing module 103. The delivery completion message includes: delivery completion time and delivery path. Specifically, the optimal delivery path can be sent to the driver of the selected transport vehicle, and the driver drives the transport vehicle of the corresponding model to pick up the goods from the optimal supplier, and delivers the diesel vehicle exhaust treatment liquid to the gas station requesting liquid replenishment according to the optimal delivery path.

[0105] (7) After receiving the delivery completion message, the delivery information processing module 103 sends the delivery completion message to the liquid replenishment information processing module 102, and the liquid replenishment information processing module 102 sends the delivery completion message to the filling machine information processing module 101, thereby completing a delivery task.

[0106] The operation of searching for the best supplier in step (2) and step (4) includes: finding a supplier whose inventory is greater than the replenishment amount and is closest to the filling machine corresponding to the filling machine identifier (i.e., the filling machine that needs to be replenished) among the diesel vehicle exhaust treatment fluid suppliers 40. Specifically, find a supplier whose inventory is greater than the replenishment amount from all diesel vehicle exhaust treatment fluid suppliers 40, and then find a supplier whose inventory is greater than the replenishment amount and is closest to the filling machine corresponding to the filling machine identifier from among the suppliers whose inventory is greater than the replenishment amount, and use the supplier as the best supplier.

[0107] [Example 7]

[0108] Furthermore, after receiving the liquid unloading completion message from the liquid unloading machine, the filling machine information processing module 101 sends the liquid unloading completion message to the liquid replenishment information processing module 102. After receiving the delivery completion message and the liquid unloading completion message, the liquid replenishment information processing module 102 stores the delivery completion message and the liquid unloading completion message in the database, so as to facilitate statistics on the liquid replenishment of each filling machine, and compare the liquid unloading completion message with the liquid replenishment request message to determine whether the liquid replenishment amount in the liquid replenishment request message and the liquid unloading amount in the liquid unloading completion message are the same. If they are different, an alarm is issued to remind the staff to check the link where the problem occurs. In this way, problems that may occur during the liquid unloading process can be timely known.

[0109] If the system receives multiple refilling request messages at the same time, it can refill each filling machine separately, or arrange a transport vehicle to refill multiple filling machines, and determine the best supplier and the best delivery route based on actual conditions.

[0110] [Embodiment 8]

[0111] like Figure 5 As shown, the operation of repairing the filling machine includes:

[0112] The filling machine information processing module 101 sends a maintenance request message to the maintenance center 20. The maintenance request message includes: the filling machine identification, model, abnormal operating parameters;

[0113] After receiving the maintenance request message, the maintenance center 20 dispatches a technician to the site to repair the filling machine according to the maintenance request message. After the maintenance is completed, the maintenance center 20 sends a maintenance completion message to the filling machine information processing module 101. The maintenance completion message includes: filling machine identification and maintenance time. The filling machine information processing module 101 stores the maintenance completion message in the database. In this way, there is no need to station maintenance personnel at each gas station. When a fault occurs, the maintenance center 20 can arrange maintenance personnel to go to the site for maintenance, which reduces maintenance costs.

[0114] [Example 9]

[0115] If the filling machine installation design module receives sales volume exceeding standard messages for multiple times, the filling machine modification design and installation will be carried out.

[0116] like Figure 6 As shown, the operation of modifying, designing and installing the filling machine includes:

[0117] The model and quantity of the filling machine are determined according to the sales volume in the sales volume exceeding the standard message, and a suitable installation plan is designed (the installation plan can be designed using the existing design method, which will not be repeated here). Then, a filling machine purchase message is sent to the filling machine procurement module 105. The filling machine purchase message includes the filling machine identification (the filling machine identification of the filling machine whose sales volume exceeds the designed sales volume), the filling machine model, quantity, and installation plan. The location of the filling can be known according to the filling machine identification.

[0118] When a gas station needs to install a new filling machine, or a newly built gas station needs to install a filling machine, the gas station sends a filling machine installation request message to the filling machine installation design module 104. The filling machine installation request message includes: gas station number, sales data, and floor area. The address of the gas station can be known based on the gas station number.

[0119] like Figure 7 As shown, the operation of designing and installing the filling machine includes:

[0120] After receiving the request message for installing the filling machine, the filling machine installation design module 104 determines the model and quantity of the filling machines that need to be installed at the gas station based on the sales data, and designs a suitable installation plan based on the floor space (the installation plan can be designed using existing design methods, which will not be repeated here), and sends a filling machine purchase message to the filling machine procurement module 105.

[0121] The filling machine purchase message includes the gas station number, the model, quantity and installation plan of the filling machine. The filling machine installation design module 104 can realize the optimal design of the newly installed filling machine, avoiding the situation that each gas station decides the model and quantity of the filling machine by itself, which may lead to unreasonable design plan. If each gas station decides the model and quantity of the filling machine by itself, after blindly installing the filling machine, the filling machine may not be suitable for the gas station, and it is necessary to dismantle the unsuitable filling machine and reinstall the new filling machine, which not only affects the normal operation of the gas station, but also increases costs and reduces work efficiency.

[0122] The operation of determining the model and quantity of the filling machine that needs to be installed at the gas station according to the sales data includes: determining the model and quantity of the filling machine according to the monthly sales volume of diesel in the sales data, for example, a ton tank type filling machine can be used for a monthly sales volume of more than 500 tons of diesel, and a 3-5 ton split type filling machine can be used for a monthly sales volume of 2,500 tons of diesel. The corresponding model and quantity of the filling machine are selected according to the monthly sales volume, so that the installation of the filling machine can meet the filling volume of the gas station from the beginning, avoiding blind installation of the filling machine.

[0123] After receiving the filling machine purchase message, the filling machine purchasing module 105 prepares a bid document according to the filling machine purchase message, and sends the filling machine purchase message to the filling machine manufacturer. The filling machine purchase message includes the bid document and the time when the bid document is sent.

[0124] After receiving the message of purchasing the filling machine, each filling machine manufacturer participates in the bidding. Then the filling machine manufacturer that wins the bidding completes the production of the filling machine and installs the filling machine at the gas station. After the installation, the supplier sends a successful installation message to the filling machine purchasing module 105. The successful installation message includes: filling machine identification, filling machine model, installation time, and maintenance date. The filling machine purchasing module 105 updates the filling machine information in the database in the cloud server according to the successful installation message, and records the newly installed filling machine identification, model, gas station to which it belongs, installation time, maintenance date, and other information.

[0125] If the filling machine is to be installed not only at the gas station but also in other places, such as at the entrance of a convenience store, then these places will send a filling machine installation request message to the filling machine installation design module 104, and the gas station number in the filling machine installation request message can be replaced with the number of the place. The model, quantity and installation plan of the filling machine can be designed according to the actual situation of the place, and the other steps are the same as the above steps for installing the filling machine at the gas station.

[0126] The content of the message transmitted in each of the above embodiments can be designed according to actual needs, and the message transmission can be realized by using various existing communication protocols.

[0127] [Example 10]

[0128] The cloud server further includes a database, in which a filling machine form, a gas station form, a diesel vehicle exhaust treatment fluid supplier form, and a filling machine supplier form are stored;

[0129] The filling machine form stores the specific information of each filling machine, including the filling machine identification, the gas station to which it belongs, the address, the model, the installation date, the maintenance date, the liquid level value, and the operating parameters;

[0130] The gas station form stores the specific information of each gas station, including the number, address, and sales data of the gas station;

[0131] The diesel vehicle exhaust treatment liquid supplier form stores the number, address, product parameters, production volume, and inventory of each diesel vehicle exhaust treatment liquid supplier;

[0132] The filling machine supplier form stores the number, address, product model, output, and inventory of each filling machine supplier.

[0133] The information stored in each form in the database can be designed according to the actual situation, and each form can be updated at any time according to changes in the actual situation.

[0134] The system and method of the present invention improve the efficiency of filling, repairing and installing a new filling machine, and reduce the cost.
