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

The present invention relates to a device for managing the driving speed of an old industrial vehicle, and more particularly, to a device that can be attached/detachable horizontally to the interior of an old industrial vehicle while defining an accommodation space within the structure of the old industrial vehicle. type travel speed detection box>, <the location point value, acceleration, angular velocity, and location point value of the old industrial vehicle are installed in the receiving space of the travel speed detection box and are electrically connected to the battery for power supply on the old industrial vehicle side In addition to measuring noise data corresponding to acceleration and angular velocity, the measured position point value, acceleration and angular velocity are corrected based on the noise data to estimate and calculate the traveling speed of the old industrial vehicle, Driving speed management unit that can determine whether or not to speed>, <In the state of being electrically connected to the driving speed management unit, it is drawn out of the driving speed detection box through a wire, and in a state attached to the exterior of the old industrial vehicle , When the driving speed of the old-fashioned industrial vehicle is determined to be overspeed by the driving speed management unit, a warning light capable of outputting a warning light> is systematically arranged/provided, and through this, on the side of the driving entity of the old-fashioned industrial vehicle In, only a very simple procedure of simply attaching a detachable/attachable driving speed detection box, a warning light, etc. to the interior/exterior of the old industrial vehicle, within the structure of the old industrial vehicle, 'overspeed alarm' unrelated to the impact applied from the wheels By inducing the easy provision/application of a 'speed sensor having a function', in the end, without experiencing any problems of time/money damage due to complex installation of the sensor or damage to the sensor due to shock applied from the wheel, etc. , It relates to a driving speed management device for older industrial vehicles 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 capable of supporting their effective operation have been widely developed/distributed.

For example, Korean Patent Registration No. 10-969561 (Name: Brake Interval Adjustment Device for Construction Equipment and Industrial Vehicles) (Announced on July 12, 2010), Korean Patent Registration No. 10-1089207 (Name: Forklift and Construction Equipment) Parking brake system for vehicles) (published on Dec. 5, 2011), Korean Registered Patent No. 10-1444742 (Title: gearbox driving device for construction equipment and industrial vehicles) (published on Sep. 26, 2014), Korean Patent Publication No. 10- No. 2015-123534 (Name: Industrial and construction heavy equipment access monitoring and operation control system) (2015.11.04), Korea Utility Model Publication No. 20-2018-3062 (Name: Forklift attachment for excavators) (2018.10. 24) discloses an example of a conventional support technology related to industrial vehicles in more detail.

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

Usually, in the case of new industrial vehicles, for example, as disclosed in Korean Patent Publication No. 10-2011-35674 (Name: Forklift driving speed warning device and method) (published on April 6, 2011), from the time of manufacture, Since it is equipped with a speed sensor having a series of overspeed alarm functions, it is possible to prevent collisions caused by overspeed in advance.

However, unlike these new industrial vehicles, in the case of older industrial vehicles that have been out of stock for a long time, since they do not have a separate speed sensor at all, unless a separate measure is taken, the old industrial vehicle that is self-driving on the worker's side It is not possible to easily detect whether or not the vehicle is speeding, and eventually, it is inevitable to be exposed to a crash caused by speeding.

Conventionally, in consideration of the problems of collision accidents of older industrial vehicles, new sensors for measuring speed, such as wheel sensors and hall sensors, are newly installed on wheels of older industrial vehicles, and through this, overspeed driving of older industrial vehicles We are trying to find a way to block it.

However, in order to newly install sensors for measuring speed, such as the wheel sensor and hall sensor, on the wheel of an old industrial vehicle, for example, after dismantling the previously assembled wheel, the sensor for measuring speed (wheel sensor, hall sensor, etc.) sensors, etc.), as well as newly setting up complicated wiring and reassembling the wheel with the sensor for measuring speed back to the old industrial vehicle. On the side of the subject, there is no choice but to bear the huge financial and time damages caused by it.

In particular, when sensors for measuring speed (wheel sensors, hall sensors, etc.) are installed on the wheels of older industrial vehicles, the sensors for measuring speeds (wheel sensors, hall sensors, etc.) are separately blocked from the enormous shock applied to the wheels. /Without a buffering means, it is forced to be applied as it is, and in the end, the operator of the old industrial vehicle has no choice but to bear the problem of damage to the sensor for measuring speed (wheel sensor, hall sensor, etc.).

In short, the conventional 'method of installing speed measurement sensors (wheel sensors, hall sensors, etc.) on the wheels of old industrial vehicles' is only a very unrealistic method that is not easy to apply in practice, and in the end, separate measures are required. Unless is taken, the operator of old industrial vehicles cannot easily solve the 'problem of collision accidents caused by speeding of old industrial vehicles'.
