Hereinafter, a wiring structure for a specially equipped vehicle according to an embodiment of the present invention will be described with reference to a powder or granular material carrier, which is an example of a specially equipped vehicle. Although not shown, the powder and granular material carrier procures from a chassis manufacturer a chassis on which an engine is mounted as a driving source for traveling, and a working device and a controller that operate by receiving the driving force of the engine are mounted on the chassis. The manufacturer installs it and ships it to the requester (customer). Engine specifications (for example, idling speed, minimum engine speed, or maximum engine speed with respect to the voltage value (driving value) of the engine, which will be described later) differ for each chassis manufacturer. The specifications of the engine set for each chassis maker are stored in the storage means provided in the controller mounted on the specially equipped vehicle. A chassis manufacturer is a manufacturer that manufactures a chassis on which an engine is mounted, excluding work equipment. called a maker.

The working device is composed of a compressor that introduces pressurized air through an introduction pipe into a tank that stores the granular material. The pressurized air from the compressor causes the granular material in the tank to flow and is configured to be discharged to the outside through a discharge pipe. The compressor is provided with a rotation speed sensor as rotation speed detection means for detecting the rotation speed (output value) of the compressor. The compressor is provided with a rotational speed sensor as measuring means for detecting the rotational speed (output value) of the compressor and measuring the actual output value. A working device is one that receives mechanical motion directly from a drive source. For example, in this embodiment the compressor is subject to the rotational motion of the engine.

As shown in FIG. 1, the wiring structure of the specially equipped vehicle includes drive source side wiring (drive source side cable) 3 extending from an electronic governor 2 for keeping the number of revolutions of the engine 1 constant, and extension of the drive source side wiring 3. Controller-side wiring (controller-side cable ) 9. The second connector 5, the third connector 6, and the controller-side wiring (controller-side cable) 9 connecting the two connectors 5 and 6 constitute a setting harness (selection means), which will be described later. Here, four types of setting harnesses are provided. The first connector 4 has a different shape for each chassis manufacturer, and the second connector 5 has a shape corresponding to the shape of the first connector 4, which varies for each chassis manufacturer. With this configuration, the controller-side wiring 9 for each chassis maker can be identified just by looking at the shape of the second connector 5 . The fourth connector 7 has a shape common to each chassis manufacturer. This is because the controller 8 can be shared. Wiring (conversion wiring) is required for connecting the first connector 4 for each chassis maker to the common fourth connector 7 . Therefore, in the present invention, a selection circuit 11, which will be described later, is provided in the third connector 6 constituting the conversion wiring. This eliminates the need for a dedicated wiring with a selection circuit in addition to the conversion wiring. One of the first connector 4 and the second connector 5 is configured as a female type, and the other is configured as a male type so that it can be inserted into the female type. Similarly, one of the third connector 6 and the fourth connector 7 is configured as a female type, and the other is configured as a male type so that it can be inserted into the female type.

The storage means 33 of the controller 8 stores information on the specifications of a plurality of drive sources (engines in this case) that differ for each chassis manufacturer. The information includes, but is not limited to, the idling speed of the engine and the minimum and maximum speeds of the engine 1 for each chassis manufacturer.

As shown in Figures 2 and 3, the fourth connector 7 comprises a plurality of selected circuits 10 for accessing one of a plurality of information, and the third connector 6 comprises a fourth The selection circuit 11 is electrically connected to one selected circuit 10 out of the plurality of selected circuits 10 by connection with the connector 7 . Therefore, only by connecting the fourth connector 7 and the third connector 6, one selected circuit 10 out of the plurality of selected circuits 10 is electrically connected. When replacing the controller with a new one, information on the specifications of the drive source (engine) mounted on the specially equipped vehicle can be selected without making a mistake.

Each of the selected circuits 10 includes an idling circuit 12 for setting an idling speed of the engine that differs for each chassis maker, and a working device (compressor) that is operated by the driving force of the engine to set the speed of the compressor for work. A working circuit 13 is further provided. By connecting the third connector 6 to the fourth connector 7, the idling circuit 12 of the engine mounted on the specially equipped vehicle and the working circuit 13 of the compressor are simultaneously connected. By connecting the third connector 6 to the fourth connector 7 in this way, the idling circuit 12 of the engine mounted on the specially equipped vehicle and the work circuit 13 of the compressor are connected, thereby increasing the idling speed and the speed of the engine mounted on the specially equipped vehicle. The compressor speed can be set at the same time.

In this embodiment, the controller 8, that is, the storage means 33 (see FIG. 8) of the control unit 30, which will be described later, stores the engine idling speed and the compressor speed (minimum engine speed or the number of revolutions at the maximum engine speed) is stored. The term "stored" includes both software storage as a program and hardware storage as a circuit. The third connector 6 is composed of four types of third connectors 6a, 6b, 6c and 6d. The first third connector 6a is a first selection circuit for selecting the idling circuit 12 of the chassis manufacturer of company A. 14, and a second selection circuit 18 for selecting the work circuit 13 for reading the upper limit value and lower limit value of the rotation speed of the compressor of the compressor manufacturer combined with A company. Further, the second third connector 6b is connected to a first selection circuit 15 for selecting the idling circuit 12 of the chassis manufacturer of Company B, and the upper limit value and lower limit value of the rotation speed of the compressor of the compressor manufacturer combined with Company B. and a second selection circuit 19 for selecting the working circuit 13 for reading out. The third connector 6c is connected to the first selection circuit 16 for selecting the idling circuit 12 of the chassis manufacturer of Company C, and the upper limit value and lower limit value of the rotation speed of the compressor of the compressor manufacturer combined with Company C. and a second selection circuit 20 for selecting the working circuit 13 for reading out. The fourth third connector 6d is connected to a first selection circuit 17 for selecting the idling circuit 12 of the chassis maker of Company D, and the upper limit value and lower limit value of the rotation speed of the compressor of the compressor maker combined with Company D. and a second selection circuit 21 for selecting the working circuit 13 for reading out.

Specifically, FIGS. 2(a) to 2(d) show the idling circuit 12 of the fourth connector 7 and the four types of first selection circuits 14, 15, 16, 17 of the third connector 6. FIG. The fourth connector 7 has resistors with different resistance values A to D from four chassis manufacturers. The idling speed is read and the voltage value is output to the electronic governor 2 . In other words, different resistance values result in different voltage values, and the idling speed of each chassis manufacturer is read according to the different voltage values. In FIG. 2(a), by being connected to a resistor A, the idling speed of the engine of chassis maker A is read out. In FIG. 2(b), by connecting to the resistor B, the idling speed of the engine in the case of the chassis maker B company is read. In FIG. 2(c), by connecting to the resistor C, the idling speed of the engine of chassis maker C is read. In FIG. 2(d), by connecting to the resistor D, the idling speed of the engine of chassis maker D is read out.

3(a) to 3(d) show the working circuit 13 of the fourth connector 7 and the four types of second selection circuits 18, 19, 20, 21 of the third connector 6. FIG. Note that the second selection circuit 21 is in a state of no circuit. The fourth connector 7 has GNDs 22 and 23, and SET1 and SET2 which have an output value of 0 when connected to the GNDs 22 and 23 and an output value of 1 when not connected to the GNDs 22 and 23. By connecting each third connector 6 to a fourth connector 7, the upper limit value (maximum engine speed) and the lower limit value (minimum engine speed) of the engine of each chassis maker (referred to as preset command values to be described later) can be read out. It has become. In FIG. 3(a), by connecting SET1 and GND 23 on the lower side, the output values become "0" and "1", and the upper limit value and lower limit value of the engine of chassis maker A are read out. In FIG. 3(b), by connecting SET2 and GND 23 on the lower side, the output values become "1" and "0", and the upper limit value and lower limit value of the engine of chassis maker B are read out. In FIG. 3(c), by connecting SET1 to the lower GND 23 and SET2 to the upper GND 22, the output values become "0" and "0", and the upper limit value and lower limit value of the engine of chassis maker C are read out. . In FIG. 3(d), there is no circuit in the third connector 6, and when the fourth connector 7 is not connected to the fourth connector 7, the output value becomes "1" and "1". Read the upper and lower limits. The upper limit and lower limit of the engine of each chassis manufacturer A to D correspond to the upper limit and lower limit of the compressor rotated by the output of the engine.

Further, a meter panel 24 shown in FIG. 4 is attached to the granular material carrier. This meter panel 24 is used when discharging the granular material in the tank and when setting at least one of the upper limit and lower limit of the rotation speed of the compressor 25 (see FIG. 5). Specifically, a main switch 26, a rotation speed adjustment switch 27 for the compressor 25, and a screen changeover switch 28 are arranged in order from the top on the right end of the meter panel 24, and a liquid crystal meter screen 29 as a display unit is provided in the center of the left and right portions. It has

The main switch 26 consists of a toggle switch, and is configured as an alternate operation type that switches to an ON or OFF state and maintains the switched state by tilting the operating lever upward or downward only once. Here, when the operation lever is tilted upward, the compressor 25 is switched to work (ON state), and this state is maintained until the next operation (downward operation) is performed. In addition, when the operation lever is pushed downward, it is switched to the running state (OFF state) in which the specially equipped vehicle runs, and this state is maintained until the next operation (upward operation) is performed.

The rotational speed adjusting switch 27 constitutes output value adjusting means for varying the rotational speed, which is the output value of the compressor 25 when the compressor 25 is in operation. Specifically, the rotation speed adjustment switch 27 is a toggle switch that is urged to return to the neutral position, which is the horizontal posture shown in FIG. 4, when not operated. It is configured as a momentary operation type that turns ON only when it is tilted to the side. Here, when the operation lever is tilted upward, the rotation speed of the compressor 25 is increased. Further, when the operation lever is pushed downward, the rotation speed of the compressor 25 is decreased. If the number of rotations of the compressor 25 is to be changed continuously, the operating lever must be held in the upward or downward position. The rotation speed adjustment switch 27 also functions as a fine adjustment switch as fine adjustment means for finely adjusting the minimum rotation speed (lower limit value) and the maximum rotation speed (upper limit value) of the compressor 25 .

The screen changeover switch 28 consists of a toggle switch, and is biased so as to return to the neutral position, which is the horizontal posture shown in FIG. 4, when it is not operated. It is configured as a momentary operation type in which only one switch is in the ON state. Here, when the operation lever is tilted upward, the screen is switched, for example, to the meter screen 29 shown in FIG. In addition, the value of the trip meter (running distance meter) can be reset by tilting the operation lever downward and maintaining the tilted state for a predetermined time (several seconds) (pressing and holding). The screen changeover switch 28 also functions as a determination memory switch as determination means for determining the minimum and maximum rotation speeds of the compressor 25 set by the rotation speed adjustment switch 27 .

The meter screen 29 shown in FIG. 5 displays the number of revolutions (850 rpm in FIG. 5) of the compressor 25 driven by the power from the engine 1 (see FIG. 5), as well as the measured value of the pressure gauge in the tank (see FIG. 5). 5) and the measured value of the pressure gauge in the pipe (0.175 MPa in FIG. 5) are displayed. Although not shown, it is also possible to switch to the operation information screen, and the operation information screen displays the total operating time of the compressor, the operating time of the compressor today, the temperature of the compressor, error display and error history, etc. is displayed.

Further, as shown in FIG. 8, operation signals from the rotation speed adjustment switch 27 and the screen changeover switch 28 are input to the control unit 30, and the engine 1 and the compressor 25 are connected or disconnected. A power take-off device (PTO) 31 capable of switching between the connected state and the cut-off state of the power take-off device 31 is connected to the controller 30 .

The control unit 30 includes a controller 8 and storage means 33 . In the storage means 33, a plurality of voltage values of the upper limit value and the lower limit value of the engine speed are stored as preset command values for each chassis manufacturer. Since the difference between the upper limit and the lower limit of is small, one rotation speed is stored as a preset command value. The storage means also stores a gain, which is the width of increase or the width of decrease when the rotational speed adjustment switch 27 is operated upward or downward during work to operate the compressor 25 . Since there is no difference in gain for each compressor manufacturer, one gain is stored. Then, by inserting the third connector 6a or 6b or 6c or 6d of one of the four types of setting harnesses into the controller 8, the setting mode is switched to and which chassis maker's engine is identified. Then, the voltage value that generates the specified minimum engine speed and the corresponding rotation speed of the compressor 25 (which is rotated by the torque of the engine) are read out. The read voltage value and the rotation speed of the compressor 25 are displayed on a setting screen, which will be described later.

6 and 7 show the process of setting the minimum rotation speed (lower limit of output value) and maximum rotation speed (upper limit of output value) of the compressor 25, which are necessary when assembling the powder carrier. will be explained based on

First, the controller 11 is mounted on the granular material carrier (step S1). Next, the setting mode is switched to by inserting the third connector 6 of the setting harness into the fourth connector 7 of the controller 8 (step S2). Next, the engine 1 is started, the changeover switch 32 is turned on to turn on the power takeoff device (PTO) 31 (connected state), and the main switch 26 is pushed upward to switch to "during operation" (step S3). . At this time, it is determined that the power take-off device (PTO) 31 is electrically connected by the ON signal of the switch 32. The number of revolutions of the compressor 25 that operates on the voltage value is read out (the setting harness constitutes selection means). As a result, the meter screen 29 is switched to the setting screen shown in FIG. The upper part of FIG. 6 shows the rotation speed of the compressor 25 at 700 rpm when the minimum rotation is set and the rotation speed of the compressor 25 at 900 rpm when the maximum rotation is set. Subsequently, by inserting the setting harness into the controller 8, the engine 1 is driven at the drive voltage value (preset command value of 2.20 V) corresponding to the read minimum engine speed (step S4). By this driving, the current drive voltage value of the engine 1 and the rotational speed of the compressor 25 actually measured by the measuring means are displayed (step S5). At this time, due to individual differences in the engine 1 and the compressor 25, a display different from the pre-stored minimum rotation speed (preset command value) is displayed. In the upper part of FIG. 6, the voltage value is 2.20 V and the rotation speed is 760 rpm. (see the middle section of ). After the adjustment, the screen changeover switch 28 is pushed downward for a long time to set the minimum rotation speed (regular lower limit value) (step S6). This set minimum number of revolutions (regular lower limit) is stored as the lower limit in the storage means 33 (step S7). After storage, the rotational speed is raised to the maximum rotational speed of 900 rpm (the voltage value at this time is 2.50 V) by tilting the rotational speed adjustment switch 27 upward (see the lower part of FIG. 6). When the maximum rotation speed reaches 900 rpm, the screen changeover switch 28 is pushed downward for a long time to set the maximum rotation speed (step S8). The set maximum number of revolutions (regular upper limit) is stored as the upper limit in the storage means 33 (step S9). After saving, the inserted setting harness is removed from the controller 8 to switch to the work mode (step S10). After switching, the operation of the compressor 25 is checked (step S11), and if it is confirmed that the operation is normal, the setting work is completed. Here, the minimum rotation speed is made to match from 750 rpm to 700 rpm, but the minimum rotation speed may be adjusted so as to approach 700 rpm.

In addition, by setting prohibited areas (two areas, the lowest area and the highest area) where the minimum and maximum rotation speeds cannot be set for each chassis manufacturer, it is possible to avoid an error in the engine 7. ing.

For example, the specially equipped vehicle of the present invention is not limited to the powder carrier. It may be configured to be variable when the working device is operated, or may be constant without being variable. Here, as a work device driven by an engine, there is a work device that applies energy to a cargo by a fluid moved by the work device to load the cargo into or out of the vehicle. It should be noted that the fluid to be moved by the work device may be the load itself. The granular material carrier of the present embodiment applies pressure to the granular material (load) with air (fluid) compressed by a compressor, which is a working device, and discharges the cargo. A tank truck is an example of a load that is moved by a working device. In this case, a pump, which is a working device, applies pressure to petroleum (load), which is a fluid, to load or discharge petroleum. Further, as a working device driven by an engine, there is one having an actuator that converts a fluid moved by the working device into mechanical motion. There are two types of loading and unloading by moving the machine on board with this actuator or by the machine moved by the actuator. For example, there is a concrete pump vehicle with a concrete pump that regulates the amount of concrete delivered during operation. This concrete pump has a hydraulic pump and a hydraulic cylinder, and the hydraulic cylinder (actuator) is moved by hydraulic oil (fluid) pressurized by the hydraulic pump (working device). The hydraulic cylinder moves the boom (machine) or another hydraulic cylinder (actuator) to eject the concrete. A pump that applies pressure to hydraulic oil is sometimes called a hydraulic pump, and a pump that applies pressure to cargo is sometimes called a loading/unloading pump. A specially equipped vehicle equipped with a hydraulic pump operates a hydraulic actuator with the hydraulic pressure of the hydraulic pump. The amount of oil discharged from the hydraulic pump corresponds to the output value of the working device. Specially equipped vehicles equipped with loading and unloading pumps also include the granular material carrier of the present embodiment. As another example, there is a garbage truck that generates electricity with a working device. The working device of the garbage truck is the generator. The garbage truck supplies electric power from a generator to a motor, drives a hydraulic pump with the motor, drives a hydraulic actuator with hydraulic oil pressurized by the hydraulic pump, drives a loading device with the hydraulic actuator, and discharges garbage. load the

The detection means may be composed of a rotation sensor for detecting whether the compressor 25 is rotating or a sound sensor for detecting a sound when the compressor 25 is rotating. In this manner, the driving voltage value (driving value) of the engine (driving source) is read based on the detection signal from the detection means, and the compressor (working device) is operated. Fine adjustment of the measured value is not performed while the compressor (working device) is not electrically connected.

Further, in the above embodiment, the engine 1 is used as the drive source for traveling, but an electric motor driven by a battery may be used.
