Description

Technical Field

[0001] The present invention belongs to the technical field of sanitation vehicles, and in particular relates to a control system and a control method for a vertical station transfer vehicle. Background Art

[0002] With the continuous development of mechanized and intelligent production equipment, the types of sanitation machinery in my country are increasing. The increase in sanitation industry equipment also puts forward higher requirements for saving manpower, reducing labor costs, and improving work efficiency. The characteristics of mobile stations for rapid compression and flexible transportation make them more and more widely used, and various types of transfer vehicles have emerged.

[0003] The collection and transfer of vertical stations is more difficult than that of horizontal mobile stations. When loading, the vertical station transfer vehicle needs to use its arm that can be flipped from horizontal to vertical state, connect the vertical station and lock it, and then reset the arm to rotate the vertically placed station body ninety degrees to lie on the vehicle. When unloading, the vertical station transfer vehicle also needs to use the arm flip to drive the station body locked on the arm to rotate ninety degrees to a vertical state and land. In the above process, due to the structural characteristics of the vertical station, it is inevitable that the arm will contact the ground in the process of flipping from horizontal to vertical state and from vertical to horizontal to form a force point that causes the vehicle to be stressed, which is enough to cause the wheels of the transfer vehicle to leave the ground and cause danger. In order to overcome this danger, almost all vertical station transfer vehicles currently operate in a non-parking state. The advantage of this method is that when the arm flips from horizontal to vertical state and from vertical to horizontal, it will contact the ground to form a force point that causes the vehicle to be subjected to backward and forward traction, so that the vehicle can move with the traction force, thereby eliminating the danger of wheels leaving the ground. However, the major drawback of this method is that it allows the vertical station transfer vehicle to operate while in motion, which may lead to more serious consequences if the operator does not operate in a standardized manner or makes an error in operation. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a vertical station transfer vehicle control system and control method, which solves the contradiction between the transfer vehicle needing to move in a working state and not operating in a driving state.

[0005] The present invention provides the following technical solutions: In the first aspect, a vertical station transfer vehicle control system is provided, including a data acquisition unit for collecting status information of a chassis and an operating mechanism of the transfer vehicle; a data processing unit connected to the data acquisition unit, for receiving status information of the chassis and the operating mechanism, judging whether the transfer vehicle is in a workable state or a non-workable state according to the status information of the chassis and the operating mechanism, and issuing an alarm instruction in the non-workable state; an operating unit connected to the data processing unit, for sending a job request to the data processing unit; an alarm unit connected to the data processing unit, for issuing an alarm message according to the alarm instruction of the data processing unit; when the data processing unit judges that the transfer vehicle is in a workable state, the data processing unit responds to the job request sent by the operating unit, and sends a job instruction to the operating mechanism; when the data processing unit judges that the transfer vehicle is in a non-workable state, the data processing unit does not respond to the job request sent by the operating unit, and sends an alarm instruction to the alarm unit.

[0006] As an optional technical solution of the present invention, the chassis status information collected by the data collection unit includes handbrake status, gear status and chassis rear wheel pressure data.

[0007] As an optional technical solution of the present invention, when the chassis status information is handbrake triggered and neutral, the data processing unit determines that the transfer vehicle is currently in a parking state; when the chassis status information is handbrake released and neutral, the data processing unit determines that the transfer vehicle is currently in a working state, and if the chassis is subjected to traction, it will move; when the chassis status information is not neutral, the data processing unit determines that the transfer vehicle is currently in a driving state.

[0008] As an optional technical solution of the present invention, the parking state and the driving state are both non-operating states.

[0009] As an optional technical solution of the present invention, the operating mechanism status information collected by the data collection unit includes boom position information and contact status with the vertical station box.

[0010] As an optional technical solution of the present invention, when the operating mechanism is in a state where the boom is flipped and the boom has not slid back to its original position, the data processing unit sends an alarm instruction to the warning unit, and the warning unit issues an alarm message; when the operating mechanism is in a vertical state of the boom and is in contact with the vertical station box, the data processing unit sends a lock closing instruction to the operating mechanism.

[0011] As an optional technical solution of the present invention, the data processing unit compares the chassis rear wheel pressure data p with the preset pressure values ​​p1 and p2. If p1≤p≤p2, the unit determines that the transfer vehicle is in an operable state; if p>p2, and the operating mechanism is in contact with the vertical station box, the transfer vehicle is determined to be in an inoperable state; if p>p2, and the operating mechanism is not in contact with the vertical station box, the transfer vehicle is determined to be in an operable state.

[0012] In a second aspect, a control method for a vertical station transfer vehicle control system based on the first aspect is provided, comprising: obtaining status information of a transfer vehicle chassis and an operating mechanism; judging whether the transfer vehicle is in an operable state or an inoperable state according to the status information of the transfer vehicle chassis and the operating mechanism; if the transfer vehicle is in an operable state, sending an operating instruction to the operating mechanism, and if the transfer vehicle is in an inoperable state, restricting the operating mechanism from operating.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The vertical station transfer vehicle control system provided by the present invention analyzes the status information of the transfer vehicle chassis and the operating mechanism through a data processing unit, determines whether it is currently in a working state, and issues different instructions according to different states, thereby solving the contradiction between the transfer vehicle being subjected to force and needing to move in a working state and not operating in a driving state. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 is a schematic diagram of a control system for a vertical station transfer vehicle in an embodiment of the present invention; Figure 2 It is a flow chart of the vertical station transfer vehicle control method in an embodiment of the present invention. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0016] Example 1 This embodiment provides a vertical station transfer vehicle control system, such as Figure 1 As shown, it includes a data acquisition unit for collecting status information of the chassis and the operating mechanism of the transfer vehicle. A data processing unit is connected to the data acquisition unit and is used to receive the status information of the chassis and the operating mechanism, and judge whether the transfer vehicle is in a workable state or a non-workable state according to the status information of the chassis and the operating mechanism, and issue an alarm instruction in the non-workable state. An operating unit is connected to the data processing unit and is used to send a job request to the data processing unit. An alarm unit is connected to the data processing unit and is used to issue an alarm message according to the alarm instruction of the data processing unit.

[0017] In this embodiment, the chassis status information collected by the data collection unit includes handbrake status, gear status and chassis rear wheel pressure data.

[0018] Further, when the chassis status information is a handbrake trigger and neutral gear, the data processing unit determines that the transfer vehicle is currently in a parking state. When the chassis status information is a handbrake release and neutral gear, the data processing unit determines that the transfer vehicle is currently in an operable state, at which time the chassis does not actively move, and moves if the chassis is subjected to traction. When the chassis status information is non-neutral gear, the data processing unit determines that the transfer vehicle is currently in a driving state. Both the parking state and the driving state are inoperable states.

[0019] In this embodiment, the operating mechanism status information collected by the data collection unit includes boom position information and contact status with the vertical stand box.

[0020] Furthermore, when the operating mechanism is in a state where the boom is flipped and the boom is not reset, the data processing unit sends an alarm instruction to the warning unit, and the warning unit sends an alarm message. When the operating mechanism is in a vertical state of the boom and is in contact with the vertical station box, the data processing unit sends a lock closing instruction to the operating mechanism. This prevents the operator from executing the lock closing when the operating mechanism is in a vertical state. If it is not in contact with the box at this time, there is a risk of damaging the structure.

[0021] Furthermore, the data processing unit compares the rear wheel pressure data p of the chassis with the preset pressure values ​​p1 and p2. If p1≤p≤p2, the unit determines that the transfer vehicle is in an operable state. If p>p2, and the operating mechanism is in contact with the vertical station box, the transfer vehicle is determined to be in an inoperable state; if p>p2, and the operating mechanism is not in contact with the vertical station box, the transfer vehicle is determined to be in an operable state. During the process of the vertical station transfer vehicle loading and unloading station body leaving the ground and landing, all forces will be transmitted to the rear wheels of the chassis. If the rear tire pressure exceeds the limit, there is a risk of tire blowout, which reduces the service life. The system automatically judges, reminds, and limits to prevent the operator from causing this risk due to oversight or mistakes.

[0022] When the data processing unit determines that the transfer vehicle is in an operable state, the data processing unit responds to the operation request sent by the operating unit and sends an operation instruction to the operating mechanism; when the data processing unit determines that the transfer vehicle is in an inoperable state, the data processing unit does not respond to the operation request sent by the operating unit and sends an alarm instruction to the warning unit.

[0023] Example 2 This embodiment provides a control method based on Embodiment 1.

[0024] like Figure 2As shown, specifically including: Obtain status information of the transfer vehicle chassis and operating mechanism.

[0025] The transfer vehicle is judged to be in an operable state or an inoperable state according to the status information of the transfer vehicle chassis and the operating mechanism; if the transfer vehicle is in an operable state, an operating instruction is sent to the operating mechanism; if the transfer vehicle is in an inoperable state, the operating mechanism is restricted from operating.
