Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a gas delivery system and method, and a gas container management method.
Efficient delivery of various gases such as oxygen, nitrogen, carbon dioxide, and semiconductor material gas from gas suppliers to gas users in various forms such as liquefied gas loaded on tank trucks, liquefied gas filled in gas containers, or high-pressure gas Systems and methods capable of doing so.

[0002]

2. Description of the Related Art For example, in the delivery of gas from a gas supplier (manufacturer) to a gas user, each user manages the gas amount at each point of use, and When the quantity reaches a predetermined amount, the gas order is ordered from the manufacturer, and the manufacturer instructs the delivery department (gas delivery base) to deliver the gas based on the order, and the delivery department based on the delivery instruction. A predetermined amount of gas is delivered to each user (use point).

[0003] Therefore, it is necessary for each user to have a gas manager who checks the amount of gas, performs an ordering operation, and performs an inspection at the time of delivery. Also, whether inside or outside the company,
In some cases, the delivery of gas was delayed due to a communication error, or a large number of orders were received at once, resulting in a shortage of gas inventory.

Further, when the gas to be delivered is a liquefied gas and the liquefied gas loaded on the tank lorry is delivered to the liquefied gas storage tank at the point of use, as a problem at the time of liquefied gas delivery, the amount of liquefied gas delivered must be clearly determined. There is also a so-called full tank system in which delivery is completed when the amount of liquid in the storage tank is not specified and the tank is full, usually when the tank is full. Sometimes returned to the base. In addition, a small lorry may have to be delivered for small orders, and the liquefied gas carrying capacity of the lorry cannot be fully exhibited, which has led to an increase in distribution costs.
This problem is the same also in the delivery of gas containers filled with gas, and moving to delivery without loading only a few gas containers on the truck can not make full use of the loading capacity of the truck, Logistics costs are wasted.

In the case of a gas filled in a gas container,
At the time of shipment from the filling factory and delivery to the user, information on the gas container and its movement is recorded. However, in the intermediate distribution stages of relay bases and business offices, since these records are hardly taken, the location and condition of the gas container could not be sufficiently grasped.

[0006] For this reason, for example, there is a case where a stock is delivered to a user from a filling factory via another business office or the like, even though the stock is in a business office relatively close to the user. In some cases, a great waste of time, labor, and cost occurs.

[0007] Furthermore, small users who use less gas, such as hospitals and clinics handling medical oxygen, may be operating in residential areas with narrow roads, so that large lorries and trucks may use gas. Delivery was sometimes impossible. For this reason, it is necessary to deliver gas to such users using small lorries and trucks from distribution bases and filling factories, and large users who can deliver gas with large vehicles nearby. Even if there were, gas users could not be delivered at the same time as large users, so small users had to perform their own management.

Accordingly, an object of the present invention is to provide a gas delivery system and a gas container management system which can reduce the distribution cost by efficiently delivering various gases.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic block diagram showing a first embodiment of a system configuration of a gas delivery system according to the present invention, and illustrates a case where a liquefied gas is delivered. First, the liquefied gas is generally supplied to the production bases 11, 12,
13 to be produced and stocked, respectively, lorries 21 and 22
2. Liquefied gas storage tanks 31, 3 at each use point
Delivered to 2,33,34.

Each liquefied gas storage tank 3 at the use point
1, 32 and 33 are each provided with a liquid amount measuring means 41 such as a liquid level gauge, and the stored amount information measured by the liquid amount measuring means 41 is used as important use point information through a network. Inventory management monitoring system 51 via
The amount of liquefied gas used per unit time is calculated based on changes in the amount of stored liquid, and is averaged for one hour, one day, one week, etc., maximum used, and minimum used. Is stored in the storage device as a past gas use history.

Other use point information includes a user name (company name, business name), a location, a type of liquefied gas including purity, a capacity of a liquefied gas storage tank, and a stockout level for issuing a remaining amount reduction warning. Operating conditions such as continuous or intermittent use, handling of hazardous materials and fire, business hours of operation, holidays,
Various kinds of information such as delivery handling time, form of lorries that can be entered, and other fixed point information, stockout level information, safety management information, etc. regarding use points are selected as necessary and input to the inventory management monitoring system 51. And stored in a storage device or the like.

The gas base information such as the production amount and the stock amount at each production base or the liquefied gas sending base associated with the production base is transmitted to the production inventory management system 52 via a network.
Is sequentially input to the computer and managed. As the gas base information, base name (factory name), location, maximum and minimum production amount, maximum stock amount, production plan, filling capacity, and other information related to the gas base are selected as necessary. And stored in the storage device.

Further, the gas distribution information such as the current positions of the lorries 21 and 22 and the arrangement of the lorries at the vehicle bases 23 to 26 to which the lorries belong is sequentially input to the computer of the vehicle allocation support system 53 via the network. Be managed. The gas delivery information includes the base name,
The location, the loading capacity and type of each vehicle, the number of trolleys placed at the depot and the number of drivers, transportation capacity based on these, transportation plans, road information such as road closures and congestion, and other information on depots are selected as necessary. The information is input to the vehicle allocation support system 53 and stored in the storage device.

The computers of the inventory management monitoring system 51, the production inventory management system 52, and the vehicle allocation support system 53 are interconnected, and make optimal delivery plans and production plans based on the information. In addition, each system, the liquid amount measuring means 41, each base, and each vehicle (lorry) are connected via an appropriate communication means such as a dedicated communication line, a telephone line, wireless, a portable terminal, etc. Forming a network.

By constructing such a system, there is a great difference in the management of liquefied gas between a gas user in the network and a gas user outside the network. That is, users in the network
A self-serving delivery user who can manage the liquefied gas storage tank, that is, gas management such as gas usage and gas stock via communication means (network),
The user does not need to perform cumbersome management of the liquefied gas storage tank, thereby reducing management costs, and the producers and distributors as gas suppliers use the gas consumption and gas inventory obtained through the network. By appropriately delivering (delivery and supplying) the liquefied gas based on the gas management information such as the amount, it is possible to reduce distribution costs and improve production efficiency.

On the other hand, a gas user outside the network is a general user as in the past, and the gas user himself performs monitoring of the amount of liquefied gas used, inventory, etc., and gas management such as ordering work. The delivery of the liquefied gas to the general users is performed by ordering the gas supply from each general user to the gas supplier.

That is, by constantly monitoring the amount of liquid in each liquefied gas storage tank in the network by the inventory management monitoring system 51, the amount of gas used per unit time (hour, day, week, month, etc.) can be grasped. From the amount of liquid in the storage tank and the amount of gas used, it is possible to calculate the time or the number of days until a stockout in which the liquefied gas disappears. For example, the liquefied gas storage tank 31
Has a storage capacity of 10000 m ³ and a low remaining warning line
000m ^3, when the gas amount of the past hour obtained from gas usage history information of 200 meters ^3, the liquefied gas level is 2000
must deliver the liquefied gas within 10 hours After becomes m ^3, it deliverable amount is 8000 m ³ at present is outputted from the inventory management monitoring system 51 as shortage level information.

In this case, optimal conditions for the delivery of the liquefied gas,
For example, liquefied gas can be delivered under optimal conditions in consideration of the mileage, time, loading capacity, and the like of a gas delivery vehicle. For that purpose, first, a lorry that is loaded with a liquefied gas of the same type as the liquefied gas in the liquefied gas storage tank 31 and that can deliver the liquefied gas to the liquefied gas storage tank 31 is provided near the liquefied gas storage tank 31. Whether the vehicle is running is searched based on the vehicle information and the transportation plan information stored in the vehicle allocation support system 53, and if the corresponding lorry 21 is found, the lorry 21 is instructed to deliver the liquefied gas to the liquefied gas storage tank 31. I do.

The loaded liquefied gas is stored in the liquefied gas storage tank 3.
The state in which delivery is possible to 1 is a state in which the amount of liquid stored in another liquefied gas storage tank to be delivered has room to the shortage level, and the next day's delivery is in time. At the same time, based on the information on the type of the lorry 21 and the information on the location of the liquefied gas storage tank 31,
First, it is determined whether the liquefied gas can be delivered, for example, in consideration of the road width relative to the size of the lorry.

If there is no lorry as described above, the liquefied gas is transmitted from each vehicle base via each gas base by referring to the vehicle base information from the vehicle allocation support system 53 and the gas base information from the production inventory management system 52. In consideration of the road to the storage tank 31 and road conditions, a vehicle base having a lorry capable of reliably delivering liquefied gas within 10 hours and within an acceptable time and a gas base corresponding to the vehicle base are selected as candidates, Among them, for example, the depot 23
And the production base 11 is selected.

At this time, if the stock amount of the corresponding liquefied gas is insufficient due to the stock information from the production base 11, another production base 12 is selected and this production base 12 is selected.
Select a depot at a location suitable for the location of the vehicle. The selection of the lorry at the depot is first performed on condition that the liquefied gas storage tank 31 can be entered and a predetermined amount can be delivered.
If there is room, a semi-trailer class of 12 to 13 tons is selected, and in a narrow place or a small liquefied gas storage tank, a 2-ton class, 4-ton class, or 8-ton class lorry is appropriately selected.

At the same time, the state of the other liquefied gas storage tanks 32 to 34 is confirmed, and the total amount of gas delivered from the vehicle can be 80% or more, preferably 90% or more of the gas loading capacity of the vehicle. 2. Select a third liquefied gas storage tank. Second,
In selecting the third liquefied gas storage tank, not only the location information and the liquefiable gas deliverable amount but also the liquefied gas reception information such as holidays and after hours, and road information in the vicinity are referred to.

For example, the liquefied gas storage tank 32 is
Or it is near the liquefied gas storage tank 31 and can be delivered
Is 3000m³From the vehicle depot 23
Loading capacity 10,000m³Of lorries and production base
Liquefied gas 10,000m at 11 ³Liquefied gas
The liquefied gas is stored in the storage tank 31 and the liquefied gas storage tank 32, respectively.
Delivery location, delivery quantity, delivery order (direction), etc.
Delivery instruction information to the lorry via the depot, or
Directly to the lorry.

Thus, the loading capacity of the lorry is 1
Since the liquefied gas of 0000 m ³ can be delivered to each of the liquefied gas storage tank 31 and the liquefied gas storage tank 32, the transportation capacity of the lorry can be maximized. Also,
By taking into account road information such as winter snow cover, disasters, road closures due to intensive construction, and traffic congestion due to accidents, the second and third destinations are determined so that the travel time and distance (distance) are minimized. , Lowering lorry fuel costs, reducing maintenance and parts replacement costs, extending vehicle life,
It is also possible to reduce labor costs by shortening the working hours of the driver. In addition, it is possible to optimize the type of lorry to be deployed at each depot, and there is also an effect that an operation plan can be easily created by unifying vehicle types.

The amount of liquefied gas delivered depends on the liquefied gas storage tank 3.
8000m per 1³Deliver the rest to the liquefied gas storage tank 32
The liquefied gas storage tank 32 may have³,
The remainder may be delivered to the liquefied gas storage tank 31,
Both liquefied gas storage tanks 31 and 33 are, for example, 5000 m³Each
The delivery quantity can be changed to be delivered. Further
The liquefied gas storage tank 33 near the liquefied gas storage tank 31
Out of stock level information due to unusual increase in gas usage
If liquefied gas is delivered to the liquefied gas storage tank 31,
Delivery to the liquefied gas storage tank 33
From the liquefied gas storage tank 32 to the liquefied gas storage tank 33
5,000 m in the liquefied gas storage tank 31 ³, Liquefied gas
2000m in storage tank 32³3000 in the liquefied gas storage tank 33
m³It can be sorted as follows.

As described above, the liquefied gas is appropriately delivered by the gas supplier on the basis of the amount of liquefied gas used and stored in each of the liquefied gas storage tanks owned by the self-serving delivery users in the network. In each installed liquefied gas storage tank, it is as if the gas supplier and the gas user are connected by virtual piping, that is, virtual piping (registered trademark), greatly burdening the user with liquefied gas management and the like. Can be reduced.

That is, by delivering the liquefied gas from the gas supplier to the gas user through the virtual pipe as described above, each user can freely use the liquefied gas without worrying about the amount of the liquefied gas. While being able to use it with your heart,
Even at the gas supplier, each production base can make a production plan based on information such as the amount of gas used from the inventory management monitoring system 51. Therefore, by efficiently operating the air separation device and the like, the liquefied gas Manufacturing costs can be reduced. In addition, since the necessary inventory at production bases and liquefied gas delivery bases can be optimized, the worst situation of inventory shortage can be avoided, and inventory burden due to having a large inventory is reduced, and capital investment is optimized. Can also be planned.

Furthermore, at each vehicle depot, the location and consumption of each liquefied gas storage tank on the user side, and the location, production and inventory of the production and shipping bases on the supplier side, etc. Since an operation plan can be made, liquefied gas can be transported and delivered more efficiently, and the number and type of lorries to be deployed can be optimized.
It is also possible to ensure the number of operating personnel while taking into account working conditions. In addition, the number of deliveries (purchases) can be reduced as compared with the case where liquefied gas is delivered individually, so that logistics costs such as the number of lorries, the number of times of filling, mileage, and fixed costs can be significantly reduced.

In addition, by planning the delivery of liquefied gas in consideration of weather information and various event information, for example, when a typhoon, a torrential downpour, or a drunk snow is expected, the delivery is set earlier. By doing so, shortage due to a delivery delay can be reliably prevented. If the surrounding road conditions are expected to be different from normal times due to international events, take measures such as studying a detour or distributing to a depot or production base that is in charge of other areas. Can take.

On the other hand, when a gas sales company or a dealer receives an order for liquefied gas from an independent user (general user) not incorporated in the network,
Order information from the user, for example, a company name or the like is input to a terminal installed at a gas sales company or the like, and a vehicle base and a production base (shipping base) closest to the user are selected by the production inventory management system 52 and the dispatch support system 53. Then, the vehicle allocation support system 53 outputs a lorry transportation command.

At this time, not only the information of the lorries waiting at each of the vehicle bases 23 to 26 but also the position information of the lorries 21 and 22 existing outside the bases can be used as a criterion. If the stock amount is insufficient, another production base is selected, and a vehicle base suitable for the selected production base is selected again.

The lorry receiving the instruction enters the designated production base, loads the full amount of liquefied gas, faces the user, and delivers the liquefied gas to the user's storage tank. The amount of liquefied gas delivered from the lorry is taken into the network from the lorry driver or user's manager through means such as a terminal, and the amount of liquefied gas remaining in the lorry is determined by the inventory management monitoring system 51. And the vehicle allocation support system 53.

The inventory management monitoring system 51 determines the liquefied gas storage tank capable of delivering the liquefied gas in the lorry from the liquefied gas remaining amount of the lorry and the storage amounts of the liquefied gas storage tanks 31 to 34 incorporated in the network. Is selected as a delivery candidate. The selection of the liquefied gas storage tank may be one or plural depending on the remaining amount of the liquefied gas in the lorry. Further, various information such as the location information of the liquefied gas storage tank selected as a candidate, the remaining amount of the liquefied gas, and the receiving state,
Based on the lorry position information from the vehicle allocation support system 53, the shortest mileage, the shortest time, and a liquefied gas storage tank that can deliver gas under optimal conditions in consideration of a vehicle with an optimal capacity is selected as a delivery location. Information such as a delivery place, a delivery amount, and a delivery order (road direction) is transmitted to the lorry via the vehicle allocation support system 53.

By supplying a predetermined amount of liquefied gas sequentially around the designated liquefied gas storage tank, it becomes possible to deliver 80% or more, preferably 90% or more of the liquefied gas loaded on the lorry. Therefore, the lorry in which a large amount of liquefied gas is left unloaded does not return to the depot.

For example, when the lorry loads 10,000 m ³ of liquefied gas and delivers 7000 m ³ to the user, one or a plurality of liquefied gas storage tanks capable of delivering the remaining 3000 m ³ are selected, and at least 1000 m ³ , preferably 2000 m ³ or more is set to be delivered to any of the liquefied gas storage tank. As a result, even if the amount delivered to the user is uncertain, the loading capacity of the lorry can be maximized, and even if the amount delivered to the user is small and a large amount of liquefied gas remains in the lorry, By appropriately delivering to the liquefied gas storage tank connected by virtual piping like this, it is possible to maximize the transportation capacity of the lorry and to efficiently deliver the liquefied gas by virtual piping .

Further, at one of the use points,
Even when the amount of liquefied gas used has been significantly changed, for example, when the amount of liquefied gas used has been lost due to a factory relocation or the like, the stored amount information input to the inventory management monitoring system 51 is lost or the amount of fluctuation is reduced. It will be zero,
It is possible to respond immediately, and by sending this information from the inventory management monitoring system 51 to the production inventory management system 52 and the dispatch support system 53, the production plan at the nearest production base can be reviewed, and Immediate measures such as reviewing the operation plan can be taken. Conversely, if the amount of liquefied gas used increases significantly, it can be dealt with immediately by increasing production, using production bases in other areas, transferring lorries from vehicle depots in other areas, etc. Such a serious situation does not occur.

Further, as a gas user (point of use), for example, as in a clinic handling medical oxygen, the gas consumption is small and the stock capacity is scarce.
There are small users whose location is narrow. Normally, such small users are treated in the same manner as other users, and based on the above-mentioned use point information, gas base information and gas distribution information, select a small car that can be delivered to that point of use and Make a delivery.

In general, a plurality of such small users exist in an urban area or a residential area in many cases. In such a case, in the area where these small users exist, the same user is referred to using the use point information. Search for use points (large users) that can enter large vehicles and have appropriate inventory capacity in the area or in the neighboring area, and once deliver the gas delivered to the small users to the large users In addition, in the case of a liquefied gas, a gas is delivered to a small-scale user by loading the gas into a small lorry or filling a portable liquefied gas container. In the case of gas filled in a gas container, a large-scale user is required to store the gas container, and the gas container is transported to the small-scale user using a small truck or a van.

As described above, by configuring the system so that the gas is delivered to the small user via the large user, the gas delivery from the gas supplier to the point of use can be performed for the large user. Since it is only necessary to deliver a large amount of gas at a time, it is possible to significantly reduce the logistics cost of gas delivery compared to loading and transporting a small amount of gas from a distant depot on a small truck. This makes it easier to create a transportation plan. At this time, the transfer of the gas from the large user to the small user may be performed by a relay base or a sales office on the gas supplier side, and depending on the conditions, the large user may be substituted.

Even in such a case, the use point information of each small user is collected and stored in the same manner as the other use point information, so that the gas consumption can be grasped, the gas delivery time can be calculated, and the gas delivery time can be calculated. The calculation of the delivery amount is performed in the same manner as described above, and the calculated delivery time and delivery amount are treated as a part of the gas usage amount for large users. As a result, even if it is necessary to deliver gas from a large user to many small users at once, gas can be delivered to a large user including the small user, so that a large user, Both small users will not be out of stock.

The consumption forecast 121, the delivery plan 122, and the production plan 1 calculated by the calculation processing in the calculation server 120
23, the distribution plan 124, the vehicle allocation plan 125, and the like are stored in the storage device 130 and transmitted from the communication device 140 as various types of information. That is, each use point 1
To 60, gas delivery information (P) 141 such as gas delivery time and gas delivery amount based on the delivery plan 122 is mainly transmitted. The gas transport base 170 transmits delivery instruction information (Q) 142 such as a gas purchase base (gas production base, relay base), a gas delivery destination (use point, relay base), and a route based on the vehicle allocation plan 125. Also, the production base 150
, The production instruction information (R) 143 is transmitted based on the production plan 123 and the distribution plan 124.

Then, the gas transport base 170 arranges a driver based on the delivery instruction information (Q) 142, and the like.
Make or modify vehicle operation plans. Also,
Also at the production base 150, the production instruction information (R) 143
The operation plan of the gas production apparatus is made or revised based on the information. As a result, the production and delivery of gas based on the information obtained from each use point 160 is ensured, and
It can be done without waste.

FIG. 4 is a flowchart showing an example of a monitoring procedure in the monitoring system for monitoring the liquid amount, pressure, and discharge amount of the liquefied storage tank at the use point 160 using the liquefied gas and transmitting it to the receiving server 110. is there. In the liquefied gas storage tank, step 201 of measuring the amount of liquid in the liquefied gas storage tank with a liquid level gauge or the like, step 202 of measuring the pressure in the liquefied gas storage tank with a pressure gauge or the like, flow rate of the liquefied gas discharge from the liquefied gas storage tank Step 203 of measuring with a meter or the like and step 204 of measuring other data such as gas temperature and atmospheric temperature are continuously performed, and each measurement data is sequentially sent to a storage device and stored (step 205). ).

Each measurement data stored in the storage device is compared with a set value stored in advance in the storage device in step 206. At this time, if an abnormality is recognized in the measurement data (Y), the process proceeds to step 207, where the measurement data is transmitted to the receiving server. If no abnormality is found in the measurement data (N), the process proceeds to step 208, and it is confirmed whether a request for transmission of the measurement data has come from the receiving server. If no transmission request has been received (N),
Returning to step 205, the measurement data is stored, and the process of comparing the measurement data with the set value in step 206 is repeated.
If a transmission request has been received in step 208 (Y), the process proceeds to step 207 to transmit the measurement data to the receiving server, and then returns to step 205.

As described above, while continuously collecting and storing various measurement data, the presence or absence of abnormality in the measurement data is confirmed.
If abnormalities are found in the measured data, by sending the measured data to the receiving server immediately, measures such as urgent delivery of liquefied gas can be taken, for example, even if the liquid volume suddenly decreases. In addition, it is possible to quickly cope with a decrease in the heat insulation performance of the liquefied gas storage tank and a failure of the measuring device.

FIG. 5 is a flowchart showing an example of a procedure of the storage tank group monitoring system in the central processing unit 100 when the measurement data is received from the use point monitoring system. First, in step 211, it is checked whether the measurement data transmitted from the use point is abnormal data, and when it is confirmed that the data is abnormal data (Y).
Proceeds to step 212 to indicate that an abnormal situation has occurred on a display or the like, and further proceeds to step 213 to instruct countermeasures against the abnormality.

If it is determined in step 211 that the measured data is not abnormal data, the process proceeds to step 214,
Individual information corresponding to the storage tank that has received the data is selected from a large number of storage tank groups, and in step 215, each measurement data is stored and accumulated in a database corresponding to each storage tank. In addition, abnormal data is similarly stored.

In step 216, calculations are performed based on the liquid amount, pressure, and discharge amount in each storage tank to calculate a liquefied gas delivery plan (delivery time, delivery amount). The calculated delivery plan is compared with data 218 stored and accumulated as delivery plan data in step 217. If there is no change (N), the process returns to step 216 to calculate a delivery plan based on the next data. I do. Step 217
If the change of the delivery plan is recognized (Y), the process proceeds to step 219, where the change of the transportation plan and the production plan is instructed to the responsible department via the communication device, and the data 218 is changed.
Is updated with new delivery plan data.

As described above, based on the measurement data received from the use point monitoring system, in the case of abnormal data, a countermeasure against the abnormality is promptly taken, for example, when the amount of liquefied gas in the storage tank decreases more rapidly than the planned amount. In such a case, shortage at the point of use can be avoided beforehand by instructing measures such as emergency transportation of liquefied gas. Then, the delivery plan is calculated from the data including the abnormal data, and when there is a change in the delivery plan, the transportation and production of the liquefied gas can be ensured by instructing the change of the transportation plan and the production plan related thereto. It can be carried out.

FIG. 6 is a flowchart showing an example of a planning procedure in a transportation planning system for drafting a transportation plan with reference to the above various information. First, step 2
At 21, a transportation plan for the next day is created. At this time, the delivery plan data 218 of the storage tank group monitoring system and the use point information 131 of the storage device 130, the production / discharge plan data 234 in the production base system described later, the production information 132 of the storage device 130, and the transport information 133 The included road information, weather information 135 and vehicle information 136 are read as basic information.

For example, from the delivery plan data 218, information on the delivery destination (use point) and the delivery amount, etc., and from the use point information 131, information on the delivery destination location, the size of the storage tank, the vehicles that can enter, etc. From the payout plan data 234, information on suppliers and purchase amounts based on the production information 132, information on detours and snowfall from road information and weather information 135, information on vehicle inspection and repair from vehicle information 136, Each is read.

In step 221, a calculation is performed based on these information, and a transportation plan for the next day (vehicle allocation plan 12
Plan 5). Similarly, in step 222, a transportation plan for the next two days is prepared, in step 223, a transportation plan for three days is prepared, and in step 224, a transportation plan for four days is prepared. In step 225, these transportation plan data are stored and accumulated. The accumulated transportation plan data can be displayed on the display unit 226, and can be printed or transmitted to a related department. Then, in step 227, it is confirmed whether or not there is a change for the next day. If there is a change (Y), the process proceeds to step 228 to instruct the relevant department such as each gas transport base to make the change. If there is no change (N), the process ends.

As described above, by preparing a transportation plan based on various information, for example, the delivery plan data 218
Is changed, and a plan change instruction is given from step 219 in FIG. 5, a transportation plan can be made based on a new delivery plan, and it is possible to immediately respond to the change in the delivery plan. In addition, by preparing a transportation plan up to four days later, during normal times when there is no significant change in the gas usage at the use point, it is possible to secure enough driver staff and take extra time for vacations etc. .

FIG. 7 is a flowchart showing an example of a planning procedure in a production base system for drafting a gas production plan based on the above transport plan. First, step 23
In step 1, information on each production base, for example, information on operation status, inventory status, and the like is collected. In step 232, the optimum payout amount from each base is calculated based on the information and the transport plan data 225 prepared by the above-mentioned transport plan planning system, and a payout plan is prepared for each base. Then, based on the payout plan, a production plan is made in step 233,
It is stored and accumulated as production plan data 234.

Therefore, in this production base system, even if the gas delivery amount is changed unexpectedly, for example, the change data from the storage tank group monitoring system is used as the change of the transportation plan data 225 of the transportation planning system. Since the instruction is given, the payout plan and the production plan can be changed promptly and surely by incorporating the change and calculating again.

The storage tank group monitoring system, the transportation planning system and the production base system described above can be used in a case where a gas tank is filled and delivered in substantially the same procedure by using the storage tank group monitoring system as a gas container monitoring system. Applicable.
However, low-temperature liquefied gas such as liquefied oxygen and liquefied nitrogen
Normally, the liquefied gas storage tank at the liquefied gas production plant where the air liquefaction equipment is installed is directly transported and delivered to the liquefied gas storage tank at the point of use by lorry. When filling a gas container and delivering it to a point of use,
A complex logistics system is adopted in which a container filled with gas is once delivered to a relay base or business office at a filling factory, and then delivered to each use point. Furthermore, in the case of gas containers, it is necessary to consider the return of the empty container after using the gas at the point of use and the quality assurance period of the gas filled in the container, and these are different from liquid gas. It becomes a problem.

FIG. 8 is a flow chart showing the outline in the case where various gases are filled in a gas container (including a portable liquefied gas storage tank) and delivered to a point of use. The gas container can be delivered to each point of use. 5 shows an example of a delivery determination procedure for determining whether or not the delivery has been completed.

First, in step 251, various kinds of information are collected and monitored. The information includes the remaining gas amount at the use point. Based on the information obtained from the gas remaining amount data 261 obtained by measuring the gas usage amount, the weight of the gas container, and the like, the consumption prediction is made in step 252. The time when the remaining amount of gas at the use point becomes insufficient is calculated from the calculated and obtained consumption prediction data 262 and the gas remaining amount data 261.

From the information collected and monitored in step 251, the number of stocked gas containers at the gas production base, the gas filling factory, and the relay base is totaled, and the number of stocked containers is calculated in step 254. At the same time, referring to the remaining gas data 261, an excess or deficiency in the number of stock containers is calculated in step 255. Further, in another step 256, the quality assurance period of the gas filled in the gas container is confirmed.

Then, in step 257, it is determined whether or not the gas container can be delivered to the designated use point on the designated date based on the data and information, and it is determined that the delivery is not possible. In this case (N), the process proceeds to step 258 to indicate that the gas container cannot be delivered. If it is determined that the delivery of the gas container is possible (Y), the process ends.

At this time, in step 258, not only the calculation results of the number of insufficient gas containers and the amount of gas are displayed, but also
Distribute information to gas production bases, gas filling plants, and relay bases,
Instructs the gas container to be filled with new gas or to transport the filled gas container. It should be noted that a delivery plan, a production plan, a transportation plan, and the like can be drafted in the same manner as the liquefied gas.

When the gas is delivered in a state where the gas container (cylinder, curl, ELF, etc.) is filled at the point of use, the gas in the filling factory 300 is supplied as shown in the gas container distribution example shown in FIG. , Transportation to the relay base 310, transportation to the business office 320, and transportation to the user (use point) 330, and the used gas container is transported in the opposite direction. User 33
From 0, return to the filling factory 300.

The distribution means 341, 342, 343 such as trucks are necessarily interposed between the filling factory 300, the relay base 310, the business office 320, and the user 330. Among them, the relay base 310, the sales office 320, the user 330
Transportation of gas containers during the period is most often by truck,
Special gas is also transported by air or train. In addition, most of the gas containers have no specified user, and one gas container is delivered to various users, and moves between the filling factory and the users through a complicated distribution stage.

The gas container which has undergone such a distribution process is provided with display means for giving each gas container unique identification information, and the filling factory 300, the relay station 310, the sales office 320, The person 330 is provided with a means for reading the display means, and is formed so as to collect identification information of each gas container at each distribution stage such as delivery and return of the gas container.

That is, as shown in an example of the gas container handling network in FIG. 10, each of the filling factories 300, 301,
302, 303 and each relay base 310, 311, 312,
Each sales office 320, 321, 322, each user 330, 3
31 and 332 and the host computer 350 are connected to each other via a network, and at each distribution stage, the display means is read by a reading means to collect identification information of each gas container.

At this time, by incorporating location information and date information into each reading means, gas container distribution information obtained by adding location information and date information to the collected identification information can be obtained. This gas container distribution information, if each reading means has a communication function, directly, if not having a communication function, via a communication device of a computer provided at each filling factory or relay base, etc. The data is transmitted to the host computer 350 using a communication means such as a telephone line.

As the unique identification information in the gas container, the container number assigned to each gas container in the related art is optimal, and as a means for adding the identification information and collecting the identification information, a bar as shown in FIG. At present, the combination of the display means having the code 360 and the bar code reader is easy and the reliability is sufficient. In addition, a large amount of identification information can be automatically collected in a short time by using an IC chip. The mounting (sticking) position of the barcode when using a barcode depends on readability and
The shoulder of the gas container is most suitable from the handling situation of the gas container.

The host computer 350 stores various kinds of information such as the use point information 351, gas use plan information 352, demand forecast information 353, gas production capacity information 354, and gas container delivery capacity information 355 similar to those in the case of the liquefied gas. A receiving device for receiving, a storage device for storing these information, and a calculation unit for drafting a delivery plan, a transportation plan, and a production plan based on the information are provided. A search means is provided for accessing the host computer 350 from a base, a sales office, or a user via communication means to search for gas container distribution information stored in a storage device of the host computer 350. .

By using such a system, for example, it is possible to monitor the delivery status and return status of a gas container at an arbitrary point of use, to grasp the amount of gas used at the point of use, and to determine the initial inventory. By referring to the amount, it is possible to formulate a delivery plan such as the delivery time and delivery number of the gas container in the same procedure as in the case of the liquefied gas.

The timing of collecting the identification information at each distribution stage is, in principle, the time when the gas container moves. For example, when transferring from a gas filling factory to a truck, when carrying a gas container from a truck to a relay station,
In addition, it is performed when the location of the gas container changes. Further, it is preferable that the location information and the date information are collected simultaneously with the collection of the identification information of the gas container. However, when the transmission to the host computer is performed without delay, the communication line is identified on the host computer side. It is also possible to determine the transmission source and add such information.

Therefore, in the storage means of the host computer 350, the location of a specific gas container is loaded on a truck owned by a certain business office, for example, on what date (what time may be included). As a result, information indicating that the gas container is being transported or stored at a business office can be stored, and a large number of gas containers can be centrally managed by the host computer. Note that each piece of information may be distributed and stored in a plurality of computers, but it is preferable that any one computer can call out and use the stored information of another computer. Further, a different host computer may be used for each type of gas for oxygen, nitrogen and the like.

The type of gas charged in the gas container,
It is preferable that the purity, pressure, production lot, filling lot, user name, order code, and the like are also input as gas container identification information and stored in the host computer as gas management information. However, such information only needs to be input when shipping at a gas filling factory, and it is not necessary to collect or re-input at each distribution stage.

Further, by incorporating the gas production capacity information 354 and the gas container delivery capacity information 355 into the host computer 350, it is possible to make a production plan, a filling plan, and a delivery plan in the same manner as in the case of the liquefied gas. This can be done smoothly and reliably, and these can be properly instructed to the department in charge.

As described above, by collecting the identification information of the gas containers together with the location information and the date information and storing them in the host computer 350, the location and the state of each gas container can be easily tracked. . Further, by forming the information on the gas container stored in the host computer 350 from a distribution base such as a sales office or a relay base, and further from a terminal of a gas user or the like,
Inquiries from users and sales staff can be easily handled.

For example, by storing the type and purity of the gas together with the identification information of the gas container, the stock status of the gas container filled with the ordered gas can be compared with the order from the user to the business office. It can be immediately known and can be directly delivered to the user from the stock location, so that a sudden order can be easily handled. In particular, even when receiving orders for special gases with a small absolute number, it is possible to respond promptly, so it is possible to significantly shorten the delivery time and eliminate the loss of storing expensive special gases wastefully for a long time. it can.

Also, for a temporary increase in demand,
Since it is possible to easily and surely know the inventory status at nearby sales offices and relay bases, it is possible to take measures without significantly affecting the filling plan at the filling factory.

Further, by defining a transit point for transporting the gas container for each user, a warning is issued when the gas container is transported to an incorrect business office and the gas container is transferred to a predetermined business office. It is also possible to make arrangements to do so, and it is possible to minimize delays in delivery due to simple mistakes.

In addition, since the location of the empty container can be known, an empty container recovery plan that follows the filling plan at the filling factory can be easily planned and executed.

Then, by sequentially monitoring the state of the gas container in and out of each user, the amount of gas used by each user can be calculated, and the amount of gas remaining at the user's hand can be estimated. it can. For example, the gas usage per unit time (day, month, etc.) can be obtained from the number of gas containers based on the past order status, and seasonal fluctuations in the usage can be easily known. As a result, the next order time and the number of orders can be predicted in advance, so that the inventory amount at a sales office or the like can be optimized.

Further, by setting a minimum inventory amount based on past delivery results in advance, a warning can be issued when the inventory amount becomes low.
Furthermore, when ordering or receiving an order, setting is made so that the time of the previous order or order is confirmed. For example, a user who normally receives an order once a week may receive an order for two consecutive days. In such a case, the order can be confirmed with the user, and mistakes such as a double order can be prevented.

Further, since the delivery can be performed in consideration of the filling date and the inspection period of the gas container, the gas within the quality assurance period can be surely delivered to the user for use, and the inspection period can be reduced. If the user has a gas container that is approaching, the user can give priority to using the gas container and work to promptly collect it.

Further, it is also possible to form a virtual pipe similar to the aforementioned liquefied gas. In other words, the history of the number of gas containers used by each user (use point), use point information such as the number of stored gas containers, gas delivery information such as information on trucks carrying gas containers, filling capacity of filling factories, relay stations By monitoring the stock capacity and the gas base information such as the stock quantity, it is possible to appropriately deliver the gas containers from the business office or the like to each user before the user runs out of stock.

For example, based on the delivery amount of various gas containers such as oxygen gas, nitrogen gas, carbon dioxide gas and the past use results, it is assumed how many empty containers exist for the user, and When a gas container is delivered to a user who has used it, a truck must be filled with various gas containers at a predetermined ratio corresponding to the past usage results, and the gas type information, usage history information, Carrying gas containers by maximizing the load capacity of trucks by sequentially delivering actual containers from the nearest user and collecting empty containers in consideration of location information, road information, etc. The distribution cost can be reduced in the same manner as described above, and the user can always prepare a gas container in an amount that does not cause a shortage in a normal use state. Case (intensive use, etc.) The management of the gas container can be left to the office or the like of the gas company, it is possible to reduce the labor required for the gas management by delivery of the gas container to form a virtual pipe with the exception of.

[0102]

As described above, according to the present invention,
Between the users and producers of various gases, as well as intermediate distributors and relay stations, these can be connected as if they were connected by virtual piping. Gas can be used without worrying about a shortage, and ordering work between the user and the producer is not required. Therefore, the gas user can reduce the cost required for gas management.

Further, on the producer side, when the gas is delivered, the vehicle operation can be realized by making the most of the loading capacity of the lorry and the truck, so that the number of times of gas delivery and the number of purchases can be greatly reduced as compared with the related art. This can reduce the number of lorries and trucks, the number of times of filling, and the traveling distance, and can significantly reduce the entire distribution cost including fixed costs.

Further, since the actual usage of various gases can be accurately grasped, efficient production can be performed at the production base, and the gas production cost can be reduced. At the same time, inventory can be optimized,
Eliminating wasted inventory can reduce inventory costs and investment.

On the other hand, by collecting and storing the identification information of the gas container together with the location information and the date information, it is possible to immediately respond to sudden orders or inquiries from the user, and the case of liquefied gas and Similarly, it is possible to establish a state where the user side and the producer side are connected via virtual piping.

This eliminates the need for the user to manage the gas container, and allows the producer to efficiently produce and fill the gas. Further, in the case of a gas container, the inventory amount at a relay base or a sales office can be optimized, and the operation efficiency of a truck that transports the gas container can be improved.
