Various sensors such as a liquid surface displacement sensor, a liquid surface level sensor, and a liquid amount sensor can be used for the remaining amount information detecting unit. The transmitting unit 11 transmits the remaining amount information input from the remaining amount information detecting unit to the receiving unit of the delivery source 3. The transmission section 11 of the present embodiment is a communication interface circuit corresponding to the above-described electric communication means. Note that, as the transmission unit 11, for example, a communication terminal device using an electric communication circuit may be used. As the communication terminal device, for example, a computer, a workstation, a smartphone terminal, a tablet terminal, a mobile phone terminal, and the like can be used.

  The transmission unit 11 of another form is configured by, for example, an electronic circuit for detecting remaining amount information including a CPU (Central Processing Unit), a memory, a timer, and the like, and a communication terminal device. In the present embodiment, the CPU controls the detection of the remaining amount information at predetermined time intervals by the remaining amount information detecting unit, temporarily writes the obtained remaining amount information to the memory, and then receives the received information via the communication terminal device. Send to. When a communication terminal such as a computer, a workstation, a smartphone terminal, or a tablet terminal is used, an electronic circuit incorporated therein can be used as an electronic circuit for remaining amount information detection. Further, the CPU of the transmission unit 11 compares the remaining amount with the reference amount, and when the remaining amount is equal to or less than the reference amount, information indicating that the remaining amount is equal to or less than the reference amount as remaining amount information. You can also set to send to.

  Further, a remaining amount warning means (not shown) is provided in the tank body 20, and when the remaining amount reaches a predetermined amount (an amount larger than the reference amount for determination), the liquid is supplied to the worker at the delivery destination 2 or the like. It can also be set to signal that the time is approaching. As the remaining amount warning means, for example, a lamp, an analog meter, a digital meter, a buzzer, or the like can be used.

  More specifically, the last liquid supply date and time, the date and time elapsed since the last liquid supply date and time, and the Information such as standard liquid consumption is input in advance. Then, the CPU in the electronic circuit calculates the date and time until the next liquid replenishment is necessary based on the information and the remaining amount information, and based on the calculation result, the date and time until the next liquid replenishment is, for example, 2 It is determined whether it is within two days or more than two days, and based on the determination result that it is within two days, a control signal is sent from the CPU to the remaining amount warning means, and the lamp, the meter, etc., flash different colors, A buzzer or the like can be controlled to emit a warning sound to notify the worker at the delivery destination 2 that the liquid supply time is approaching. Further, based on the remaining amount information, it is also possible to set, for example, to blink in a different color or emit a warning sound when the amount falls below a predetermined amount. It is also possible to set so that information indicating that the refueling time is approaching is transmitted to the delivery source 3 as a part of the remaining amount information.

  Next, the computer 12 installed at the delivery source 3 will be described. A communication interface circuit (not shown) corresponding to the above-described electric communication means is connected to the computer 12. In the present embodiment, the computer 12, more specifically, an electric circuit including a CPU, a memory, a timer, and the like built in the computer 12 also serves as a determination unit and a delivery instruction unit, and the communication interface circuit serves as a reception unit. .

  In the memory, remaining amount information, current position information of the delivery vehicle 4, and the like are input through an electric communication circuit. In the memory, for example, a reference amount (numerical value) for determining remaining amount information, the capacity of the storage tank 10 (tank body 20) installed at each delivery destination 2, the liquid used at each delivery destination 2 Type, the standard amount of liquid consumed at each delivery destination 2, the last replenishment date and amount of liquid at each delivery destination 2, the address of each delivery destination 2, the remaining amount information is compared with the reference amount, and the remaining amount is calculated. A program for determining information, a program for calculating a predicted time until liquid is exhausted at the delivery destination 2 from the remaining amount information and the standard consumption amount of the liquid at the delivery destination 2, and the like are input in advance. The reference amount may be uniform irrespective of the delivery destination 2, but it is preferable to set the reference amount according to the liquid consumption amount of each delivery destination 2. The standard consumption amount of liquid at the delivery destination 2 is, for example, a value obtained by dividing the total consumption amount of the liquid in the delivery destination 2 within a predetermined period by the number of days in the predetermined period.

  The CPU functions as a determination unit and a delivery instruction unit in the present embodiment. More specifically, the CPU takes out the remaining amount information and the reference amount from the memory, compares them, and determines whether the remaining amount information is equal to or less than the reference amount. If the CPU determines that the remaining amount information is equal to or less than the reference amount, the CPU transmits instruction information including the name, address, and the like of the delivery destination 2 requiring liquid supply to the delivery vehicle 4 through the electric communication circuit. The delivery vehicle 4 is dispatched to the delivery destination 2. Further, the CPU displays the instruction information on the screen of the computer 12, and the driver / delivery person of the delivery vehicle 4 waiting at the delivery source 3 checks the screen on which the instruction information is displayed, and controls the delivery vehicle 4 by itself. It is also possible to set to deliver to the delivery destination 2. As described above, when the transmission unit 11 transmits the remaining amount information indicating that the remaining amount is equal to or less than the reference value, the computer 12 (CPU) receives the remaining amount information and stores the remaining amount information in the storage tank 10. It may be determined that the remaining amount is equal to or less than the reference value, and the instruction information may be transmitted or displayed on a screen.

  When the CPU determines that the remaining amount information is equal to or less than the reference amount, the CPU calculates an approximate amount of the liquid supply amount from the remaining amount information and the capacity of the storage tank 10 (tank main body 20) at the delivery destination 2 or the like. Then, from the remaining amount information and the standard consumption amount of the liquid at the delivery destination 2, an expected time until the liquid is exhausted at the delivery destination 2 is calculated, and the calculation result is included in the instruction information to the delivery vehicle 4. You can also set it to send. A program for executing the above calculation is input in the memory in advance.

  When there are a plurality of delivery destinations 2 that require liquid supply, the CPU determines the delivery destination 2 from the estimated time until the delivery destination 2 runs out of liquid, the address of each delivery destination 2, the current position of the delivery vehicle 4, and the like. It is also possible to determine the dispatching priority order and the dispatching route to the vehicle, and to transmit the instruction information including the dispatching route to the delivery vehicle 4. When a plurality of delivery vehicles 4 are traveling, the CPU determines a delivery vehicle that travels at a point closest to the delivery destination 2 based on the address of the delivery destination 2, the current position information of each delivery vehicle 4, and the like. 4 can be set to transmit the instruction information.

  In the liquid delivery system 1 of the present embodiment, as described above, the liquid can be supplied, for example, in units of 1 liter. That is, in the present embodiment, it is possible to replenish the storage tank 10 with an amount of liquid that is full or an amount that is not full. Utilizing this point, for example, the determination unit may be set to execute the following determination based on the delivery destination information input in advance to the memory. The delivery destination information includes, for example, the address of the delivery destination 2, the remaining amount information for each delivery destination 2, the tank capacity of the storage tank 10 (tank body 20) for each delivery destination 2, the liquid consumption history for each delivery destination 2, and the like. is there. The liquid consumption history is, for example, a data table of the past liquid consumption of the delivery destination 2 for each month.

  The determination unit first sets a group including a plurality of delivery destinations 2 based on the delivery destination information, and determines a liquid standard consumption amount for each delivery destination 2 from the liquid consumption history of each delivery destination 2 in the group. For example, the group may be set so as to include a delivery destination 2 located in the vicinity based on the address of the delivery destination 2, or may be set to include a plurality of delivery destinations 2 having the same liquid consumption history. it can. The liquid standard consumption is, for example, a daily calculated liquid consumption in the same month as the delivery month in the liquid consumption history. Next, the determination unit determines, based on the remaining amount information, the tank capacity, and the standard liquid consumption for each delivery destination 2 such that the next replenishment time is substantially the same for all the delivery destinations 2 in the group. A liquid supply reference amount unique to each delivery destination 2 is determined. Here, the term “substantially the same period” is, for example, a range of 1 to 2 days, although it differs depending on the area of the area in the group.

  The liquid replenishment reference amount can be the actual replenishment amount as long as the liquid consumption amount of the delivery destination 2 is substantially constant. If the delivery destination 2 may consume a large amount of liquid irregularly, In the case where the liquid consumption amount of No. 2 is increasing, it is preferable to add the correction amount to the liquid supply reference amount to obtain the actual supply amount. The large amount of irregular liquid consumption at the destination 2 is entered into the memory as part of the liquid consumption history. Further, the case where the liquid consumption is increasing is, for example, a case where the liquid consumption in the three months before the delivery month has increased by 5 to 10% or more compared to the same month in the previous year, or the case before the delivery month. For example, when the liquid consumption is continuously increasing over six months. The correction amount varies depending on the delivery destination 2, but may be appropriately selected, for example, from a range of about 1 to 50 liters. It is preferable that the liquid replenishment reference amount is not set to a fixed value, but is recalculated by the CPU for each replenishment opportunity based on the above-mentioned delivery destination information.

The delivery instruction unit notifies the delivery vehicle 4 of the instruction information including the liquid reference supply amount set by the determination unit or displays the information on the screen of the computer 12, and based on the notification, the delivery vehicle 4 Then, route delivery is performed to the delivery destinations 2 of the group, and a liquid of a liquid supply reference amount is injected into the storage tank 10 of each delivery destination 2. Since the liquid supply reference amount is not limited to the amount that completely fills the storage tanks 10 of all the delivery destinations 2, the case where the storage tanks 10 of the delivery destination 2 may not be fully filled due to the tank capacity or the standard liquid consumption of the delivery destination 2. Can occur.
With such a setting, the efficiency of route delivery of the delivery vehicle 4 can be improved.
