Factory Forklift Personnel Positioning Management Plan

UWB (Ultra Wideband) is a carrier free communication technology that utilizes nanosecond to microsecond level non sinusoidal narrow pulses to transmit data. UWB modulation uses fast rising and falling pulses with pulse widths in the ns range, covering a spectrum from DC to GHz without the RF frequency conversion required by conventional narrowband modulation. After pulse shaping, it can be directly sent to the antenna for transmission. The shape of the spectrum can be adjusted by the shape of a very narrow sustained single pulse and the characteristics of the antenna load. The radiation of UWB signals is very low, usually only one thousandth of that of mobile phones, so there is no interference problem with other instruments and meters when applied in industry.

The system will implement functions

1: Realize precise positioning of forklifts, real-time grasp of the position of each forklift, and based on this, develop secondary navigation for forklifts to guide forklift drivers to quickly access tires and improve their work efficiency.

2: To achieve precise positioning of factory workers, knowing the real-time position and movement history trajectory of each worker, and based on this, secondary development can be carried out to achieve collision prevention between forklifts and workers, preventing safety accidents from occurring.

If the distance is less than the preset distance, an alarm will sound. The closer the distance, the more urgent the sound will be, reminding the driver to pay attention to approaching pedestrians or forklifts!

3: Real time monitoring of forklift operation, providing second level response. Provide customers with real-time information on the specific location, operating status, and overspeed situation of forklifts. Enable decision-makers to grasp the usage status of forklifts in a timely manner and understand whether the forklifts are in operation. When the forklift exceeds the speed limit, it can also provide sound and light alarms.

Big data analysis

4: Reflecting the trajectory of forklift operation, historical trajectory maps can be queried to provide clues for holding the responsible party accountable for the frequent occurrence of forklift collisions with equipment without anyone acknowledging or correcting them.

5: Record instances of forklift speeding and other violations, and conduct speeding statistics for each forklift within a specific time frame. It is convenient for managers to understand whether the driving of each forklift driver is stable, which is helpful for evaluating the performance of forklift operators. It can also facilitate managers to educate and even transfer employees with unstable driving in a timely manner, eliminating safety hazards.

6: Provide statistics on forklift operation time, travel, and create monthly and daily reports on forklift usage. Perform statistical analysis on the usage time of each forklift. Provide the following references for managers. Check whether the forklift is fully utilized; Reduce the situation of fatigue driving and uneven work and rest, ensuring safe driving. As a reference for the management department to increase, decrease, and allocate forklift equipment, arrange the working time of forklifts reasonably.

Two dimensional positioning principle

The positioning tag sends position pulses according to the set frequency. After receiving the position pulses, the positioning base station calculates the distance between the tag and the base station, and determines the position of the tag through four distances. The location of the base station is determined during installation, and the position of the label is obtained by solving the equation.

One dimensional positioning principle

The positioning tag sends position pulses according to the set frequency. After receiving the position pulses, the positioning base station calculates the distance between the tag and the base station, and obtains the position of the tag through two distances. The location of the base station is determined during installation, and the position of the label is obtained by solving the equation.

System composition

The positioning management system mainly consists of personnel positioning management platform, positioning server, switch, and other equipment. The switch device is used to implement data uploading, mainly for receiving and uploading location data to the data server.

Base station layout

Due to the severe obstruction of the high-level metal shelves, we adopted a one-dimensional positioning mode and installed a positioning base station every 100 meters at both ends of each shelf column to achieve one-dimensional positioning of forklifts in the entire storage plant.
