technical field

The utility model relates to a forklift anti-collision system based on a single-chip microcomputer, which belongs to the auxiliary system in the field of heavy machinery equipment.

Background technique

At present, when using a forklift to transport large goods, the driver's field of vision has a blind spot, which leads to the occurrence of goods collisions. In order to successfully complete the handling task, the driver must get off the car to check the relative position distance between the cargo and the obstacle or complete the position transfer of the cargo with the cooperation of other personnel. This not only has potential safety hazards, but also reduces work efficiency.

Large-volume goods are beyond the driver's field of vision in the three directions of length, width and height. The length direction and width direction can be controlled more easily with the cooperation of other personnel, but the height direction is difficult to obtain even with the cooperation of others. control.

In order to solve the situation where the driver drives a forklift to transport large goods and there is a blind spot, it is necessary to design a system to expand the driver's field of vision and avoid collisions between large goods and other objects, so as to improve work efficiency and safety.

detailed description

In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, specific implementations will now be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the forklift anti-collision system based on the single-chip microcomputer includes a signal acquisition device 1 and a signal receiving device 2, and the signal acquisition device 1 includes an ultrasonic sensor 101, a signal processing module 102, an A/D conversion module 103, Single-chip microcomputer control module 104, coding chip 105 and wireless transmitting module 106; Signal receiving device 2 comprises the wireless receiving module 201, decoding chip 202 and single-chip microcomputer control module 203 of sequential communication connection, single-chip microcomputer control module 203 communication connection display screen 204 and alarm 205 , the display screen 204 is an LED display screen.

According to the needs of the specific situation, the signal acquisition device 1 is set at the key position of the cargo. The signal acquisition device 1 collects a relative position signal from a certain part of the cargo to the obstacle. After the signal is processed, it is transmitted to the signal receiving device 2 through the wireless transmission module 106. The signal receiving device 2 Convert the signal into an intuitive readable signal after processing for the driver's reference.

The ultrasonic sensor 101 serves as the input of the entire system, providing a signal source for the system; the display screen 204 and the alarm 205 serve as the output of the entire system, providing the driver with vision signals and alarm signals in various directions.

The single-chip microcomputer control module 104 mainly controls each module of the transmitting device. The role of the wireless transmitting module 106 is to transmit the processed signal collected by the ultrasonic sensor 101 to realize communication with the signal receiving device 2 to realize short-distance information transmission. The A/D conversion module 103 converts the analog signal collected by the sensor into a digital signal that can be processed by the single-chip microcomputer. The signal processing module 102 mainly amplifies the weak signals collected by the ultrasonic sensor 101 and eliminates interference signals at the same time. The display screen 204 displays the distance signal collected by the ultrasonic sensor and the working status of the system. The alarm 205, when the collected distance signal is less than the set threshold, the alarm 205 sends out an alarm.

When a forklift transports large cargo, signal acquisition devices 1 are installed at different positions according to the shape of the object to be transported. Therefore, when the system is working, there will be multiple signal sources. Each signal acquisition device must be numbered to solve the problem of confusion in the signal transmission process, interference with the driver's judgment, and dangerous situations.

The signal collection device 1 can be arranged at the key position of the goods according to the needs of the specific situation, and the number of the signal collection device 1 depends on the situation.
