Description

[Detailed description of the invention]

The present invention relates to a driving information recording device for analyzing and recording driving information such as vehicle speed and engine speed. Fuel costs account for a high proportion of the operating costs of vehicles, especially large commercial vehicles such as trucks and buses, and for this reason, driving information recording devices have been developed for the purpose of economical driving and rationalization of transportation. According to this device, a microcomputer system analyzes vehicle speed (hereinafter referred to as "vehicle speed") and engine speed, etc.
For example, a predetermined range for Hayabusa N

[For example, O~20.20~
40.40~6'0.60~80.8ONKm/h) expressed as a simultaneous ratio. By the way, normally for such devices, the operational information to be analyzed is determined at the design stage, and even if the user of this device wants to measure or analyze their own operational information, it is not possible to do so simply. . This invention has been made based on four such points, and is equipped with a prediction input terminal so that the user can measure the operation period or number of operations of the measurement target determined independently by the user, and the measurement content r An object of the present invention is to provide an entrainment information recording device that outputs entrainment information. This invention will be explained below based on an example. Fig. 1 is a schematic diagram of groove 1 showing the embodiment τ of this invention,

) is its input processing circuit; (4a) is a preliminary input terminal C for measuring the operation time of the object to be measured; also referred to as an operation time preliminary input terminal; and (4b) is a preliminary input terminal 7 for measuring the number of operations. Hereinafter also referred to as the preliminary input terminal for the number of assists.
, (5a) is a control circuit consisting of a start switch, (5'b) a printed switch, and (6) an H microcomputer system. After being detected by the rotary rotation speed detector (2), it is inserted through the manual processing circuit (3). Furthermore, the operation time preliminary input terminal (4a), the operation number preliminary input terminal (4a), the operation number preliminary input terminal (4a),
The operation of the embodiment of the present invention, which is configured to take into account the problems of the input terminal (4b), the start switch (5a), and the print switch (5b), will be described below. Figure (2) shows a flowchart of the microcomputer used for the control circuit 16) of Figure 1. In the figure, when the power supply to the control circuit (6) starts, the starting point (8
1), and after performing all initial settings in step (S2), the state of the start switch (5a) is determined in step (S3). Now, in order to analyze the upcoming operation information, when the start switch (5a) is closed and closed, Sugetsubu (S4) is executed and the vehicle speed counting memo IJ-V is displayed. ~v6.1A function rotation speed counting memory rI-r li

In addition, the counting memory ml of the operation-1 hour preliminary input terminal (4a) shall measure the time when the KM input terminal (4a) is at the electric fM potential, and the number of operations can be predicted. It is assumed that the counting memory mir/''i of the input terminal (41)) counts the number of times this preliminary input terminal C4b) switches from the ground level to the voltage potential. By operating the start switch (5a), the preparation for counting and storing the operation information is completed, and the serial I messenger is i4L+ll1i, -
Ω take tml start. Step (S5) is a step knob that determines whether or not to print out the minute results of the operation information at the end of the trip by inputting the 1st blank status of the print input (5b). , if the print switch (5b) is not operated, the process jumps to step [s8]. In this step (S8), it is determined whether the L/1. If it is not, it is determined that the motor is in operation.If the motor is not in operation, it is determined that the motor is not in operation.Step (S3) jumps to a higher position.Hereinafter, the explanation will be made assuming that it is in operation.In this case, step (S9) is subsequently executed. In this step (S9), T is opened for a predetermined time (for example, for 2 seconds).
The vehicle speed and engine rotation speed are determined according to the above-mentioned range (Vl
``+va, rl''''rs), and waits for a time (i-1'T, every predetermined time open T) to measure the operating time according to the state of the operating time preliminary input terminal (4a). In step (810), the memory (Vl) corresponding to the vehicle MVt (described later) and the vehicle speed V is stored.
-V5) and increment this memory money. In Sugetsubu (5ll), set the rotation speed r between one groove at this time (described later), select one of the memories Crt to R5 corresponding to this rotation speed) and increment this memory. do. For example, the following methods can be used to decrease the vehicle speed V and the rotational speed r. When the vehicle speed is determined in a row, the vehicle speed controller (1) sends out all pulse train signals in accordance with the rotation of the sword/car 1 cutter, and this Noculus train signal is applied to the interrupt processing terminal of the microcomputer system of the control circuit (6). The vehicle speed can be easily calculated by measuring the period of the pulse train No. 16 every moment using a program started by an interrupt. Furthermore, the engine speed can also be calculated using the same processing method as the vehicle speed. After step (all) is executed, in step (812), the state of the operation time preliminary input terminal (4a) is incremented by 6, the memory for operation time counting (m+75≦). That is, as mentioned above, if this fine input terminal (4a) is set to the power supply potential, it will be incremented at this step (512). , step (5lo) (8113(
512) is repeatedly executed. m1, the potential force of the input terminal (4b) for the number of times of operation ≦ 9j changes from the ground level to the power supply potential, as described above with a program that processes the 11 times. By incrementing the memory, the number of operations of the object to be measured applied to the preliminary input terminal (4) is counted. [It is sufficient to temporarily close the print switch (5b) in Fig. 11. That is, in step (S5), the print switch <, a
The open state of [b] is detected and step (S6) is executed. In this step (S6), all processing for analyzing the operation information that has been counted and stored up to now is performed. For example, I/11 would make it difficult to understand even if the total count for each predetermined flood range, such as vehicle speed and engine speed, was output as is, so calculate the ratio of each predetermined range to the total count of each predetermined item. It is easy to understand if this is outputted (described later).0 In step (S7), the analysis result obtained in the above step (S6) is outputted to the drive circuit (7).Drive circuit ゛(71

Print the analysis results. Figure 3 shows an example of this printing. (PI) shows the analysis result of the vehicle speed. For example, "20 to 40 nights = 5%" means that the vehicle speed of 2θ to 40 KmA, which accounts for the total operating time of the engine, is This shows that the cumulative open rate is 5%. As described above, this calculation can be easily calculated as the percentage of the count value of the memory IJ y- to the total of each count value of the memory vl-76. (P2) is the analysis result of the engine rotation speed "800 to 1200"
RPM: 20%" is 8% of the total operating time of 1
This shows that the ratio of engine rotational speed between 00 and 1200 rpm is 20%. The calculation method is the same as in the case of J4J-luck. (P3) indicates the operating time of the object to be measured measured by the operating time preliminary input terminal (4a) r OFT ON1:1

This shows that it was 0 sho. (P4) indicates the number of operations of the measurement target measured by the operation number preliminary input terminal (4b).
4 T MES J indicates that the number of operations was 354. As mentioned above, this embodiment analyzes the posthumous work and the information taken,
Output the camphor. By the way, if the user does not have entrainment information that he or she wants to measure independently, there is no need to connect anything to the two preliminary input terminals (4a) and (4b). In this case, the output result is (P3):
OOH00MOO8J,' (P4) rop'r
Work ON 2: It becomes OTIME8J, and both the operation time and operation confirmation are printed in cello gold.O If there is any operation information that you want to measure independently in addition to vehicle speed and engine speed, for example, the usage time of the cooler or the number of times the brakes are used. If you want to use Hong 11, connect them as shown in Figure 4. In Fig. 4, (9) is a power switch of the controller (10) of the cooler (not shown), which is configured to set the preliminary input terminal (4a) to the i1 mixed potential. When the brake (not shown) is activated, the brake switch (1 is closed) is set to the ground potential by the control circuit 6 (not shown) in the control circuit. brake light 0
2 is lit. Therefore, the pre-input terminal (4b
) is set to the power supply potential, and when there is no brake operation,
Set to 1 at ground potential. Therefore, if the user makes such a complicated external connection, the analysis results such as vehicle speed and liquid rotation speed can be displayed at the same time.
It becomes possible to easily measure the operating time of the cooler, the number of times the brake is used, etc. In addition, the time when the 171 preliminary input terminal (4a) U'4 voltage is activated is measured. Needless to say, it is easy to measure the time when the ground potential is on. The same applies to the operation count preliminary input terminal (41). Furthermore, it is also possible to easily measure both the operating time and the operation time using one pre-preparation power terminal. As explained above, the present invention is equipped with a preliminary input terminal that can measure the operation time or number of operations of the object to be measured while the vehicle is in operation, and outputs the 11 (c) value of the operation, so that the user can The value for JY is that all unique entrainment information can be measured with a simple external connection, making the device highly portable.
