The device that manages the driving speed of the old type industrial vehicles

The present invention relates to a device for managing the running speed of an old industrial vehicle, and more particularly, to a detachable/attachable device that can be horizontally attached to the interior of an old industrial vehicle while defining an accommodation space within the structure of the old industrial vehicle. Type driving speed detection box>, <Installed in the accommodation space of the traveling speed detection box, and electrically connected to the battery for power supply of the old industrial vehicle, the position point value, acceleration, angular velocity and the position point value of the old industrial vehicle , acceleration and angular velocity are measured, and the measured position point value, acceleration and angular velocity are corrected based on the noise data to estimate and calculate the driving speed of the old industrial vehicle, and Driving speed management unit capable of determining whether or not overspeeding>, <In the state of being electrically connected to the traveling speed management unit, it is drawn out of the traveling speed detection box through a wire and is attached to the outside of the old industrial vehicle. , when it is determined by the driving speed calculation unit that the driving speed of the old industrial vehicle is overspeed, a warning light capable of outputting a warning light>, etc. In, only the very simple procedure of simply attaching a detachable/attachable driving speed detection box, warning light, etc. inside/outside of an old industrial vehicle is a 'overspeed alarm' independent of the impact from the wheels in the structure of the old industrial vehicle. By inducing the easy installation/application of a 'speed sensor with a function', in the end, without experiencing any problems of time/monetary damage due to the complicated installation of the sensor, or damage to the sensor due to the impact from the wheels, etc. , It relates to a running speed management device for an older industrial vehicle that can effectively solve the problem of collision accidents caused by overspeeding of older industrial vehicles.

Recently, as the demand for industrial vehicles has rapidly increased, various technologies that can support their effective operation are being widely developed/distributed.

For example, Republic of Korea Patent No. 10-969561 (Name: brake gap adjustment device for construction equipment and industrial vehicles) (announced on July 12, 2010), Republic of Korea Patent No. 10-1089207 (Name: forklift and construction equipment) Parking brake device for vehicle) (announced on Dec. 5, 2011), Republic of Korea Patent No. 10-1444742 (name: Gearbox driving device for construction equipment and industrial vehicles) (announced on Sep. 26, 2014), Republic of Korea Patent No. 10- 2015-123534 (Name: Industrial and construction heavy equipment access monitoring and operation control system) (released on November 4, 2015), Republic of Korea Utility Model No. 20-2018-3062 (Name: Forklift attachment for excavator) (2018.10. 24. Disclosure), etc., discloses an example of a conventional industrial vehicle-related support technology in more detail.

On the other hand, under this conventional system, when an industrial vehicle (eg, a forklift, etc.) is driven at high speed inside a factory, in a yard, etc., it may cause a collision accident with nearby workers and surrounding equipment. Very close attention is paid to the driving speed of the industrial vehicle.

In general, in the case of a new industrial vehicle, as disclosed in, for example, Republic of Korea Patent Publication No. 10-2011-35674 (Title: Device and method for warning of driving speed of forklift) (published on Apr. 6, 2011), from the time of manufacture, Since a speed sensor having a series of speed alarm functions is provided, it is possible to prevent a collision accident due to overspeed in advance.

However, unlike these new industrial vehicles, the old industrial vehicles with an old departure point do not have a separate speed sensor at all, so unless a separate action is taken, the operator's side of the old industrial vehicle is self-driving. It becomes impossible to easily detect whether the vehicle is speeding, and in the end, it is inevitably exposed to collision accidents caused by speeding.

In the prior art, in consideration of the collision accident problem of the old industrial vehicle in advance, a speed measurement sensor such as a wheel sensor and a hall sensor is newly installed on the wheel of the old industrial vehicle, and through this, the old industrial vehicle's overspeed driving We are working on ways to block it.

However, in order to newly install the speed sensor such as the wheel sensor and the hall sensor on the wheel of an old industrial vehicle, for example, 'after disassembling the previously assembled wheel, the speed measuring sensor (wheel sensor, hall sensor, etc.), the process of re-setting the complicated wiring and reassembling the wheel with the speed sensor installed on the old industrial vehicle' becomes very complicated, and eventually, the old industrial vehicle is operated On the side of the subject, they have no choice but to bear the enormous financial and time damage caused by it.

In particular, when the speed sensor (wheel sensor, hall sensor, etc.) is installed on the wheel of an old industrial vehicle, the huge impact on the wheel is separately blocked with the speed sensor (wheel sensor, hall sensor, etc.) / Without buffering means, it is inevitably applied, and in the end, the operator of the old industrial vehicle has no choice but to bear the problem of damage to the speed measuring sensor (wheel sensor, hall sensor, etc.).

In short, the conventional 'method of installing a speed sensor (wheel sensor, hall sensor, etc.) Unless these measures are taken, the operator of the old industrial vehicle will not be able to easily solve the 'collision accident problem caused by the speed of the old industrial vehicle'.
