The present invention relates to an operation control method of a cleaning vehicle having a loading method such as compression, new compression, compression, and the like, and in particular, the operation of the cleaning vehicle can be controlled during operation, loading, and discharging of the cleaning vehicle through the CPU without a complicated stripping of the wires. The present invention relates to a method of controlling a sweeper using a CPU.

In the conventional method of loading garbage into a loading box of various garbage collection vehicles that have been put into a garbage collection operation, some workers in a garbage collection work group consisting of about 4 to 5 people use a garbage bin containing garbage on the ground. It lifts up to the loading tray installed in the container, or spreads various hand tools such as a shovel or samtaegi to the loading box, and another worker on the loading box takes over the garbage and stacks the garbage sequentially from the rear of the loading box. Has been loaded onto the bed. This method of loading has caused workers to always feel uncomfortable due to odors or dusts from the garbage, and also has to adversely affect the health of workers. It was a wasteful operation and a loss of working time. Also, opening and closing doors installed in the front of the loading box to load the garbage, which makes it impossible to put the garbage on the loading box, resulting in an inefficient waste collection amount compared to the loading capacity of the loading tray. Has been emerging.

Recently, the loading method is automated to operate the loading device by the button operation attached to the rear of the loading box so that when the garbage is inserted into the loading slot at the rear of the loading box, the garbage is automatically pushed into the loading box so that the garbage can be collected in a short time with little manpower.

Garbage collection vehicles, ie, cleaning trucks, are classified into route packs, clean packs, town packs, and food-only cars, depending on the loading method. , Household garbage, etc. Pressed seismic is used for collecting and treating household wastes by pressing stacking with rotating plate and dumping discharge that does not leave internal residue. The new compression material can simultaneously perform the compression and compression loading function using the rotating plate and the compression plate.It is possible to operate the rotating plate and the sealing plate used for loading once and continuously by simple button operation located at the rear of the vehicle. Unloading can be easily handled by a switch in the driver's seat. Compressed dust is to increase the loading efficiency by using a wide opening and compression plate suitable for collecting bulky waste such as home appliances and furniture.

By the way, the operation device for the loading operation of such a cleaning vehicle takes 20 to 30 places where wires are to be connected by peeling off the sheath by using a multitude of sheathed cable switches, which takes a lot of manufacturing time, and aging progresses quickly. There was a problem that the wiring was complicated and it was difficult to find the point of failure. In particular, in recent years, the application of a gas car is also applied to a cleaning vehicle in consideration of the environment. When using a low-pollution natural gas (CNG) cleaning vehicle, sparks may occur in a jumper portion of a connected electric wire, which may cause a fire.

Accordingly, an object of the present invention is to control the loading and discharging operation of the cleaning vehicle through the CPU instead of the complicated sheathed wire connection in order to solve the above-mentioned problems, reducing the manufacturing time and progress of aging, and easy to troubleshoot the CPU The present invention provides a method for controlling the operation of a cleaning vehicle.

A fourth step of retracting the mill plate by sending out a limit switch of the stop position recognition unit while reversing the mill plate; A fifth step of determining the close plate stop position by checking an input; and when the close plate stop position is determined to reach the close plate stop position, a close plate reverse stop control signal is output to the hydraulic control valve control output unit to close the close plate. A sixth step of determining the stop position of the rotary plate by stopping and checking the limit switch input of the stop position recognition unit; and when the stop plate of the rotary plate arrives at the stop position of the rotary plate, the rotating plate rotates forward to the hydraulic control valve control output unit. A seventh step of outputting a stop control signal; an eighth step of outputting a close plate forward control signal to the hydraulic control valve control output unit after stopping the rotation of the rotating plate forward; If it is the stop position to determine whether it is the stop position, the close plate advance stop control signal is outputted And a ninth step of stopping, after the completion of the ninth stage is characterized in that comprising an operation 10 which is in accordance with the activation frequency is selected in the second step is repeated return to the third step or exit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram showing an operation control apparatus for a cleaning vehicle using a CPU according to the present invention, in particular, a case where it is applied to a crimping open vehicle.

In Fig. 1, the CPU 10 is mounted with an operation program according to the compression stacking method, and executes the operation program according to the input signal to send out a control signal to perform the compression stacking function. The CPU 10 has a pin 1 connected to + 5V to receive driving power, and a pin 2 is connected to a ground GND. Toggle switches 11 for selecting loading and discharging are connected to pins 11 and 12 of the CPU 10. Pins 13 to 15 of the CPU 10 have a stop position recognition section made up of a number of limit switches LS1 to LS3 to indicate that the rotary plate and the mill have reached the position where the plate should be stopped during automatic operation. 14) is connected. Pins 17 and 18 of the CPU 10 are connected with a toggle switch 12 for selecting one time and continuous operation. Pins 19 to 23 of the CPU 10 are connected to input switches 13 for selecting forward and backward of the mill, reverse rotation of the rotating plate, operation, buzzer, and the like, respectively. A pin control output unit 15 for outputting a driving control signal to a pilot lamp P is connected to pin 24 of the CPU 10 so as to lightly display the load / discharge switch 11 input. Pin 25 of the CPU 10 is connected to the Excel controller side is connected to the Excel controller control output unit 16 for outputting a drive control signal to the Excel controller (RPM). Pin 26 of the CPU 10 is connected to a buzzer control output unit 17 for outputting a driving control signal to the buzzer so that a buzzer sounds. Pins 27 to 30 of the CPU 10 are connected to the hydraulic control valve side, respectively, and are connected to the hydraulic control valve control output unit 18 for outputting operation control signals such as reverse rotation of the rotary plate, forward rotation, tight plate reverse, and forward. . Here, the outputs 15 to 18 consist of a photocoupler and a transformer. The operation control apparatus of FIG. 1 also includes a discharge operation unit 19 for manually operating the discharge function by operating the dump and parka up and down by a toggle switch operation of the operator.

The crimping start operation control operation using the CPU of the device of FIG. 1 having such a configuration will be described in detail with reference to FIG. 2.

During operation of the cleaning truck, the operator injects garbage into the loading tray inlet at the rear of the vehicle, and operates the stacking device through a switch operation attached to the rear of the storage box. First, the CPU 10 checks pin 11 and 12 inputs connected to the loading / ejection switch 11 to determine whether the cleaning vehicle is currently loaded or discharged (step 210). Typically, the load / discharge switch 11 is in a neutral state while the sweeper is running, and one of the load and the discharge is selected according to the operator's switch operation. The CPU 10 outputs the lamp P driving control signal through the lamp control output unit 15 when the load / discharge switch 11 is operated, thereby turning on the lamp P and turning on / off the switch / load switch ( 11) is activated. Lamp P remains " OFF " while load / discharge switch 11 is neutral. If the determination result of step 210 is loaded, the CPU 10 receives the operation number through pins 17 and 18 connected to the one time / continuous switch 12 (step 220). Then, the CPU 10 receives an operation (automatic) switch input through pin 22 connected to the input switch 13 (step 230). The CPU 10 executes the mounted program so that the loading function is automatically operated as many times as the input number and performs the compression loading function (step 240). When performing the compression stacking function of step 240, the CPU 10 first forwards the rotating plate forward rotation control signal to the hydraulic control valve control output unit 18 through pin 28 to rotate the rotating plate forward (step 241). That is, the rotating plate rotates clockwise toward the inlet in accordance with the rotating plate forward rotation control signal output from the CPU 10. At this time, the CPU 10 checks whether the forward rotation of the rotating plate has passed the predetermined time "t" seconds (step 242), and closes it to the hydraulic control valve control output unit 18 via pin 29 after "t" seconds. A reverse control signal is sent to reverse the mill plate (step 243). Here, the predetermined time "t" seconds means the time required to rotate the rotating plate so that the compact plate and the rotating plate do not interfere with each other. In accordance with the close plate reverse control signal output from the CPU 10, the close plate is operated to rotate backwards, i.e., in the traveling direction of the cleaning vehicle, and the rotating plate continues to rotate. The CPU 10 checks the limit switch LS1 to LS3 input of the stop position recognition section 14 while determining that the plate holding position is rotated while the plate and the rotating plate continue to rotate (step 244). Here, the limit switches LS1 to LS3 of the stop position recognition unit 14 are installed near the position where the rotating plate should stop, the position to stop when the sliding plate enters the front and exits back, so that the rotating plate and the sliding plate are located at the installed position. When it reaches, it recognizes it and informs the CPU 10. If the determination result of the step 244 determines that the close plate stop position, the CPU 10 outputs the close plate reverse stop control signal to the hydraulic control valve control output unit 18 through pin 29 to stop the close plate (step 245). At this time, the rotating plate is near the inlet opening, the wheat plate is stopped at the top of the rotating shaft of the rotating plate. Here, step 241 to step 245 can be seen as a transport preparation step.

Then, the CPU 10 continuously rotates the rotating plate to transfer the garbage to the rear of the loading box and determines whether the current rotating plate position is the stop position (step 246). The CPU 10 determines the stop position when the rotating plate arrives at the initial setting position according to the input of the stop position recognition unit 14. If the determination result of the step 246 is the rotation stop position, the CPU 10 outputs the rotation plate forward rotation stop control signal to the hydraulic control valve control output unit 18 via pin 28 to stop the rotation of the rotation plate forward (step 247). Here, step 245 to step 247 are transfer steps.

Then, while the rotary plate is stopped at the initial setting position, the CPU 10 advances the mill plate by outputting the mill plate advance control signal to the hydraulic control valve control output unit 18 through pin 30 (step 247). In other words, the mill is rotated in the forward direction (moving direction of the cleaning vehicle) to push the garbage transported to the rear of the loading box into the storage box. At this time, the CPU 10 determines whether the current mill position is the stop position (step 248), and if the mill position is a stop position, outputs a mill forward stop control signal to stop the mill plate (step 249). That is, the CPU 10 stops the platen when it is recognized from the input of the stop position recognition unit 14 that the platen has reached the initial set position. Here, step 247 to step 249 are the loading steps.

The CPU 10 is operated once through the transfer preparation step, the transfer step, and the stacking step, and in the case of the continuous operation switch input in step 220, the CPU 10 operates continuously by repeating this.

When the waste is compressed and stacked in this way, when the operator selects the discharge by the operation of the loading / discharge switch 11, the discharge function is performed by manual operation (step 250). The discharge function is operated manually because of the risk of automatic operation. That is, the operator discharges the garbage by operating the up and down dumper and the parka up and down by a toggle switch operation of the discharge operation unit 19.

3 is a configuration diagram illustrating a case where an operation control apparatus for a cleaning vehicle using a CPU according to the present invention is applied to a compressed vehicle. As shown in FIG. 3, the operation control apparatus of the compressed vehicle is configured in the same manner as the operation control apparatus of the compressed vehicle shown in FIG. 1, and the operation program according to the compression stacking method is mounted on the CPU 30 instead of the compression. It is configured to be. The CPU 30 of FIG. 3 is also configured to control the slide and compression plate PS operation of the compressed drive vehicle instead of the rotary plate and push plate operation of the compressed drive vehicle.

Since the compressed vehicle CPU 30 also operates and operates similarly to the compressed vehicle CPU 10 described above with reference to FIGS. 1 and 2, the operation will be briefly described.

The compressed vehicle CPU 30 checks the load / discharge switch 31 input connected to pins 11 and 12 to determine whether the current work of the cleaning vehicle is loaded or discharged. In the case of stacking, the CPU 30 receives the number of one time and the number of continuous operations from the one time / continuous switch 32 connected to pins 17 and 18, and the operation connected to the number 19 pin of the plurality of switches in the input switch 33 ( Automatically performs compression loading function by receiving switch input. The CPU 30 executes a mounted loading program and transfers, compresses, and loads the waste which is introduced by controlling the slide and the compression plate up and down through the hydraulic control valve control output unit 37. The CPU 30 performs the same number of times of operation received. The CPU 30 recognizes the position at which the slide and the compression plate PS up and down should be stopped through the limit switches LS1 to LS4 of the stop position recognition unit 34 during the automatic operation. In the case of discharge, the discharge plate forward and backward and the parka up and down operation is manually operated through the discharge operation unit 39.

In the above embodiment has been described in the case of the compression and compression vehicle, it is obvious to those skilled in the art even if the case of the new compression vehicle is not described in detail.

As described above, the operation control apparatus of the cleaning vehicle using the CPU of the present invention is carried out through the CPU instead of the complicated shielded wire connection during the operation control of the cleaning vehicle having the crimping, the new pressing, and the compression loading method, thereby removing the covering one by one. No work is required, which reduces manufacturing time, slows down the aging process, and facilitates troubleshooting. In addition, when the cleaning vehicle is used as a natural gas vehicle to improve the air environment, there is an effect of improving the fire concern due to the occurrence of coating sparks.
