Description

[Detailed description of the invention]

(Technical Field) The present invention relates to a refueling device that allows remote confirmation of refueling amount wirelessly. (Prior art) For example, a fuel oil delivery vehicle is configured by storing a fuel storage tank, a fuel pump, a weighing machine, and an extendable fuel hose in a loading platform, and is parked on the road in front of a home that requires refueling. Although it is common practice to run a hose to a household oil storage tank and refuel,
Since there is a considerable distance between the display of the refueling device and the tank, there is a problem in that it takes time and effort to check the amount of refueling. Furthermore, when the refueling point and the display are separated from each other as in the case of a suspended refueling system, there is a problem in that the display is hidden behind the vehicle, making it difficult to confirm the amount of refueling. In order to solve this problem, Japanese Patent Application Laid-open No. 1983-
As shown in Publication No. 99392, a system has been proposed in which refueling data is transmitted by radio frequency, and the salesperson is equipped with a receiver to display the amount of refueling as a numerical value on a display, but this is usually not the case. While refueling,
Because they were busy checking the refueling status of the tank, they were unable to see the display on the receiving device, making it difficult to check the current amount of refueling. In order to solve such problems, for example,
A refueling device that converts the amount of refueling into an audio signal and notifies the user has also been proposed, as disclosed in Japanese Patent No. 23198. This flow rate display method eliminates the need to look at the display every time, improving work efficiency, but in environments with high noise levels, such as at a refueling station, it is difficult to hear the constantly changing refueling amount as audio. The problem is that it is extremely difficult. (Purpose) The present invention has been made in view of these problems, and its purpose is to provide a new and easy-to-hear audio notification of the amount of refueling with the optimum accuracy for the work type at the time. The purpose of the present invention is to provide a refueling device. (Summary of the Invention) In order to achieve such an object, the present invention includes a means for measuring the flow rate of fuel oil discharged from a refueling nozzle and outputting a flow rate pulse, and a means for counting the flow rate pulse and calculating it in a predetermined unit. A counting means integrates the amount of oil supplied as expressed by , and a change in the counted contents of the counting means is detected at regular intervals, and when the change occurs in the integer part, only the integer part of the counted contents is added. Speech synthesis means that converts only the decimal part of the count contents into an audio signal when a change does not occur in the integer part but only in the decimal part, and further converts the integer part and the decimal part when there is no change in the count contents. The apparatus includes a transmitting means for transmitting the audio signal as a wireless signal, and a receiving means for receiving the wireless signal and converting the audio signal into sound. (Example) The details of the present invention will be described below based on illustrated examples. Figures 1 and 2 show an example in which an embodiment of the present invention is applied to a fuel oil delivery vehicle, showing a pump 2 that receives power from an engine 11 of a vehicle 10 through a transmission mechanism 12 such as Partco, and A flowmeter 3 that measures the flow rate, and a refueling data input/output device 4 that operates by receiving power from the vehicle's battery 13.
It pumps fuel oil from an oil storage tank 14 mounted on the vehicle to a refueling nozzle 17 via a hose 16 housed in a reel 15, and supplies pulses from a flow rate pulse transmitter 5 connected to a flow meter 3. The data is configured to be output via the data input/output device 4 to a display device 18 mounted at a position where it can be read from outside the vehicle. Reference numeral 4 denotes the above-mentioned refueling data input/output device, which has a keyboard 41 on the surface of the case, a display 42, a printer 43 for printing on delivery slips and receipts, and an IC card reader, as shown in FIG.・
A writing device 44 is provided. Meanwhile, inside the case, the customer number is input from the keyboard 41.
Customer data on IC card 8 can now be accessed.
In addition, the amount of refueling obtained by counting and calculating the flow rate data from the flow rate pulse transmitter 5 is stored in the memory 50, and is displayed on the displays 18 and 42. 6 (Figure 4), customer name column 61, date column 62, and unit price,
Required data is printed in each column of refueling data 63 such as refueling amount and amount, and it is accessible.
The refueling data is stored in the customer column of the IC card 8, and the refueling amount is sampled at regular intervals, and either the integer part, the decimal part, or all digits will be described later depending on the rate of change in the refueling amount. It includes a microcomputer 45 programmed to output to a voice conversion circuit 46. Reference numeral 46 denotes an audio conversion circuit that converts digital data output from the microcomputer 45 into an audio signal as an analog signal. 47 is
The frequency modulation circuit frequency-modulates the carrier wave from the carrier wave oscillator 48 using an audio signal and outputs the resultant signal to the antenna 19 provided outside the vehicle. 49
is a counter, which is configured to count up every time the amount of refueling is sampled in response to a sampling signal from a microcomputer. Reference numeral 7 denotes a receiver owned by a salesperson, which is configured to receive radio frequency signals transmitted from a vehicle, demodulate them into audio signals, and output the signals to a speaker 71 or earphones. Note that the reference numeral 51 in the figure indicates a plug for connecting a power supply terminal. Next, the operation of the device configured in this way will be explained in the fifth section.
The explanation will be based on the flowchart shown in the figure. The salesperson receives the delivery schedule for the area he/she is in charge of and the IC card 8, and then displays the delivery schedule (Table 1).
Select a customer from , and drive a delivery vehicle to this address. The IC card 8 storing customer data is loaded into the IC card reading/writing device 44 of the refueling data input/output device 4, and the customer's customer number is input from the keyboard 41. As a result, IC card 8
It becomes possible to access the customer data area stored in the data area, and the customer name, oil type, and reservation amount stored here are displayed on the display 42, and this reservation amount is set in the data area.

[Table] After completing these preparations, engine 11
The power is transmitted to the pump 2 and the oil supply switch 52
Turn on (Step I). In this state, when the receiver 7 is worn on clothing, the fuel nozzle 17 is set in the customer's tank, and the nozzle valve is opened, fuel oil is pumped into the customer's tank by the fuel pump 2.
As a result, the flowmeter 3 is activated, and the flow rate pulse generator 5 attached thereto outputs a flow rate pulse at a frequency proportional to the flow rate, and the microcomputer 45 performs a counting operation and stores it in the memory 50. The microcomputer 45 operates for a certain period of time, for example, 1
Every time a second passes (step pro), the amount of oil supplied is sampled and the counter 49 is counted up by 1 (step pro). This sampled value is compared with the previous sampled value to determine whether a change has occurred in the integer part or only in the decimal part (Step 2). At the beginning of refueling, the amount of liquid is large, so
Since a change occurs in the integer part of the oil supply amount within the sampling period (Step 2), only the integer part of the sampled oil supply amount is output to the voice conversion circuit 46,
At the same time, reset the counter 49 (step
e). This integer part is converted into an audio signal and transmitted by the frequency modulation circuit 47 as a radio signal.
As a result, the receiver 7 generates only the integer part, that is, a value larger than Little, while ignoring the decimal part, which changes extremely quickly. As a result, the salesperson can reliably grasp the current amount of refueling based on the amount of refueling that is uttered from the receiver 7 for a certain period of time, in this embodiment, every second. In this process, a buzzer sound is superimposed when the value reaches a suitable value, for example 10, 20, etc. When the amount of refueling approaches the preset value or nears full, the flow rate of the nozzle 17 is throttled.
The difference in the amount of oil supplied within the sampling period becomes smaller, and there is no change in the integer part (step 2).
Only the decimal part will change (step
f). At this stage, the microcomputer 45
Only the last digit of the integer part and the decimal part of the refueling data are output to the voice conversion circuit 46, and at the same time the counter 49 is reset (step). As a result, the receiver 7 vocalizes the last digit of the integer part and the decimal part of the refueling amount at fixed time intervals (1 second), so even when detailed refueling operations such as integer refueling are required, Since only the data necessary for this operation is transmitted, it is possible to concentrate one's nerves. Therefore, even when the salesperson is monitoring the refueling status of the customer's tank, he or she can reliably know the amount of refueling from the data that matches the current discharge amount. Even when refueling is performed at a small flow rate, if there is a change in the integer part due to carry, all digits of the integer part are converted into voice again and the counter 49 is reset (step 2, home). ). In this way, at the time of the next sampling after the oil supply amount reaches the target value and the nozzle valve is closed, the oil supply data will have changed only in the decimal part (step Speak the last digit and the decimal part and reset the counter 49 at the same time (step). Next, since lubrication is stopped at the time of sampling, there is no change in lubrication data, and counter 4
Since the content of 9 is less than or equal to 1 (step),
Speak out the last digit of the integer part and the decimal part of the refueling data (Stepply). In this way, when the refueling operation is stopped, sampling progresses and the counter 49 counts up, and when the count number is 8 or less (step nu) and the count number N = 3n + 1 = 4,7, that is, the previous occurrence. When 3 seconds and 6 seconds have passed since then (step-off), all digits of the refueling data at the time of refueling stop will be uttered twice (step-off). Furthermore, the count value N of the counter 49 is 10n + 7 = 17, 27, 37...In other words, all digits are uttered every 10 seconds (steps) from the time when the utterance of data every 3 seconds has ended.
mosquito). When refueling is completed in this way, the frequency of vocalizing the amount of refueling is reduced, and all digits of the amount of refueling are uttered to ensure that the information is communicated to the salesperson. Note that when the refueling operation is restarted, the refueling data changes again, so the process moves from step 2 to step E or step G to transmit the digit corresponding to the rate of change of the refueling data as an audio signal. When the refueling work is completed, return the nozzle 17 and turn the refueling switch 52.
The refueling amount voice operation ends when the button is turned off (step 1). When the refueling operation is completely completed in this way, the salesperson operates the transmission mechanism 12 to cut off the power from the engine 11 and stop the pump 2 to end the refueling, and then presses the print button 40. As a result, the refueling data input/output device 4 calculates the charge based on the amount of refueling and the unit price, and calculates the charge in the customer name column 6 of the delivery note.
1. Fill in the required data in the date column 62 and refueling data column 63 using the printer 63 to issue a delivery note (Fig. 4), and at the same time store the date, amount of refueling, and amount in the customer column of the IC card 8. . If this transaction is a cash transaction, please indicate that on the keyboard 41.
When the command is issued, the computer 45 issues a receipt and at the same time stores the fact that the money has been collected in the customer column of the IC card 8. After completing the sale to the planned customer and returning to the office, the refueling data was taken out from the input/output device 4.
By loading the IC card 8 into a host computer (not shown) and issuing a processing command, it is possible to perform the day's accounting processing directly from the sales data without using a slip. FIG. 6 shows the present invention in a suspended type oil supply system, that is, the fuel oil from the pump 2 is transferred to the pipe 8 through the flow meter 3.
1 to a hose reel 82 on the ceiling, which communicates with a nozzle 84 via a hanging hose 83, and controls the refueling operation with a preset switch 85 and a hose lift switch 86 located on the wall. In the device configured to display the amount of refueling on the display 87, the refueling data input/output device 4 described above is installed in an office or the like, and
It is clear that the same effect can be achieved by having the salesperson carry the receiver 7 or by attaching it near the nozzle 84. According to this embodiment, even if the display 85 is located behind something, the amount of refueling can be confirmed. Note that reference numeral 88 in the figure indicates a transmitting antenna. In this embodiment, the audio signal is frequency modulated, but it is clear that the same effect can be achieved by amplitude modulation depending on the frequency of the carrier wave used. In addition, the sampling period and flow rate vocalization period are
It is arbitrarily selected depending on the application target. (Effects) As explained above, in the present invention, there is provided a means for measuring the flow rate of fuel oil discharged from a refueling nozzle and outputting a flow rate pulse, and a means for counting the flow rate pulse and calculating the refueling amount expressed in a predetermined unit. The counting means for integrating and the changes in the count contents of the counting means are detected at regular intervals, and if a change in the count contents occurs in the integer part, only the integer part of the count contents is detected, or if the change does not occur in the integer part. A voice synthesis means converts only the decimal part of the count contents into an audio signal when the occurrence occurs only in the decimal part, and further converts the integer part and the decimal part when there is no change in the count contents, and converts the audio signal into a wireless signal. Since it is equipped with a transmitting means for transmitting data and a receiving means for receiving a wireless signal and converting the audio signal into sound, data on the required amount of oil is automatically extracted depending on the size of the discharge flow rate, and the data can be converted into audio and audio. Therefore, you can easily hear the necessary data according to the work status.
