Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable traffic meter, which allows easy measurement of traffic volume by vehicle type per unit time.

There are two methods of measuring traffic volume by vehicle type: manual methods and non-manual methods, but the former method is inefficient;
Also, in the latter case, the device is a dog handle.

The present invention takes these points into consideration, and will be described below with reference to one embodiment of the drawings.

Figure 1 shows its appearance, and 10 is 1 to 0. A-F
The keyboard 11 has keys for a power switch, 12 a time display section, 13 a vehicle type display section, 14 a vehicle number display section,
Reference numeral 15 denotes a mode selector lever switch. For example, if the lever switch is set at the 5 minute position, the contents of the counter will be transferred to the memory in 5 minute increments.

If it is 10 minutes, 15 minutes, or 30 minutes, the contents of the counter will be transferred to the memory at the corresponding timing, or if it is a cumulative total, the contents of the counter will be transferred to the memory one after another.

16 is a switch for manually transferring the contents of the counter to memory;
17. 18 is a time adjustment knob, and 19 is a switch that can be switched between C and D sides.When turned on to the C side, the contents of the counter are incremented, and when turned on to the D side, the contents of the counter are not added. This is a switch that directs the count value of the counter to the display section 14.

Reference numeral 20 is a switch that can be switched to the M and C sides, and is used to guide the contents of the memory and counter to the display section 14.

21 is a print paper, 22 is a printer drive switch, 23
is a switch that can be switched between the PE and PI sides, and when it is turned on to the PE side, data is transferred to the memory, and when it is turned on to the PI side, it opens the print input to the printer.

Reference numeral 24 is a switch for switching between the PA and PP sides, and is used to guide the data in the memory by turning on the switch 22 when the switch is set to the PA side, and to lead the contents of the counter to the printer when the switch is set to the PP side.

25 is a terminal for supplying data to a processing device (not shown) mainly a computer, and can be an output section such as a connector or a jack.

FIG. 2 shows its specific configuration, where 26 is a clock pulse generator, 2T is a counter, and 28 is a switch 15.
29 is an OR gate, 30 (301° 302-30F) is a counter corresponding to each key 1° 2-F on the keyboard 10, 3
1 (311, 312~31F) is counter 3 in memory.
It has a function of cumulatively adding up the contents of 0 and storing the added value until a reset command is received.

32 (321, 322-32F) is a gate that guides the command from the keyboard 11 to the counter 30 only when the switch 19 is turned on; 33 (331, 332-33F);
) is a gate that transfers the contents of the counter 30 to the memory 31 only when there is an output from the OR gate 29, and 34 operates with the output of the OR gate 29, and resets the contents of the counter 30 after transferring the contents of the counter 30 to the memory 31. A reset pulse generator 35 is a reset means for resetting the contents of the memory 31, and 36 is a display driver which displays the contents of the counter 301 or the memory 31 on the display section 14 if the 1 key is turned on, while also displaying the vehicle type display section. 13 to display "1" corresponding to key 1.

37 is a battery for power supply, 38 is a printer, and 39 is a printer driver.

Next, the operation based on this configuration will be explained.

First, by turning on the power switch 11 and adjusting the display on the display section 12 using the time adjustment knobs 17 and 18, the display section 12 can display the time from now on.

Further, when the switch 15 is set to 5 minutes, an output is output to the OR gate 29 through the gate 28 every 5 minutes.

By the way, when the switch 19 is on, the output of the keyboard 10 is counted by the counter 30.

If the key 1 is now turned on, the counter 301 will increment by 1, the vehicle type will be displayed on the display section 13 through the driver 36, and the contents of the counter 301 will be displayed on the display section 14.

In this case, if the switch 19 is off, the gate 32 prevents the output of the keyboard 10 from being added to the counter 30, but the keyboard 36 displays the contents of the counter 30 or memory 31 up to the present moment on the display sections 13 and 14, indicating the type of car and its information. Display numerical values or memory values.

Therefore, keys 1 on the keyboard 10 are divided into motorcycles, keys 2 are light cars, keys 3 are passenger cars, keys 4 are small trucks, and keys 5 are buses, etc., respectively, with the same meaning, and the corresponding keys are assigned according to the type of vehicle passing at the measurement point. When you press , the counter 30 counts the number n.

When the OR gate 29 outputs an output while the counter 30 is counting, the gate 33 is opened, the contents of the counter 30 are transferred to the memory 31, and then the contents of the counter 30 are reset.

Therefore, the contents of the counter 30 are transferred to the memory 31 each time the OR gate 29 outputs.

Furthermore, by switching the switch 20 to the M side, the contents of the memory 31 can be displayed on the display section 14.

Next, the relationship between printing on the print paper 21 by the printer 38 will be explained.

If switch 23 is now switched from the PI side to the PE side, gate 3
The output of 3 is applied to the print driver 39 through switches 23 and 24.

Therefore, in the printer 38, the counter 30 is stored in the memory 31.
The data added from is printed.

When the switch 24 is switched from the PP side to the PA side, the contents of the memory 31 become input to the counter 38, and are printed when the switch 22 is turned on.

If the terminal 25 is connected to the processing device, the contents of the memory 31 are supplied to the processing device, and can be processed as traffic information by vehicle type.

When the reset means 35 is operated, the contents of the memory 31 are reset and new information from the counter 30 is accepted.

In addition, 22 to 24, 38° 39 with the section xx-x in Figure 2 as the border.
The printer system consisting of the printer system may be configured separately from other parts so that it can be docked as necessary.

Also, counter 30 excluding memory 31, gate 32゜33
etc. may be replaced by a microcomputer.

As explained above with reference to the embodiments, according to the present invention, by pressing the corresponding key on the keyboard according to the vehicle type determined by the measurer, counting and display for each vehicle type can be easily performed, and the counting of i can be performed as necessary. It can also be printed as a direct input source to processing devices, mainly computers.

Therefore, the processing in the processing device is facilitated, the processing time is shortened, and the vehicle type and count values can be easily determined per unit time.
