FIELD OF INVENTION:
[001] The present invention relates to the field of length measuring system. The present invention in particular relates to a vehicle anchored length measuring system for special purpose or military vehicles.
DESCRIPTION OF THE RELATED ART:
[002] Off - highway & military vehicles are expected to cross the canals & rivers (unprepared edges) when situation demands. During that critical situation, the accurate measurement of canal / river bed length is most critical. In those unfavorable conditions, the vehicles have to be equipped with rigid & rugged measuring tools.
[003] Reference may be made to the following:
[004] Publication No. CN108981972 relates to a vehicle-mounted measuring instrument capable of simultaneously measuring a shearing force and a cone index. The measuring instrument is mainly formed by a vacuum chuck adsorbed on a vehicle surface, a connection device with a changeable length and angle, a control center measuring box, a shearing rod which carries out actual measurement through entering into soil and a cone rod. The penetration vertical movement of the cone rod and the shearing rotation movement of a claw disc are realized respectively without affecting each other, and precision is high. An electric push rod replaces manual operation so as to control the penetration speed of the cone rod, and simultaneously, a linear displacement sensor connected to the lower portion of the electric push rod can perceive a penetration depth at any time. A screw nut mechanism in the measuring box can realize the relative movement of a box body and the fixed position of a vehicle. The claw disc with a fixed length at the lower end of the box body can be stretched into soil so as to carry out shearing force measurement. The vacuum chuck on the tail end of the measuring instrument is used to realize connection with the vehicle, dismounting is convenient, and the measurement of different orientations and different angles can be realized.
[005] Publication No. CN214985380 relates to a measuring tool for a vehicle body, which comprises a fixed rod and a measuring part, the fixed rod is arranged on the ground along a first direction, one end of the fixed rod far away from the ground is used for abutting against the outer surface of the vehicle body, and the first direction is the length direction of the fixed rod; the measuring part is arranged on the fixing rod and can move relative to the fixing rod in the second direction so that one end of the measuring part can abut against the outer surface of the vehicle body, scales are arranged on the measuring part in the second direction, and the second direction is perpendicular to the first direction. When the measuring part abuts against the outer surface of the vehicle body in the second direction, a worker visually knows the inclination or expansion condition of the vehicle body relative to the first direction through the maximum value displayed on the extending part of the measuring part. The measuring tool for the vehicle body is simple in structure and convenient to operate, is not affected by weather, can measure the vehicle body only by one worker, is efficient and rapid, reduces the labor cost of vehicle body measurement, and improves the measurement efficiency of the vehicle body.
[006] Publication No. CN111649640 relates to a size measurement tool, a whole vehicle attitude measurement tool of a vehicle and a measurement method thereof. The size measurement tool comprises a main ruler, a reference ruler and a movable ruler. The reference ruler can be switched between an unfolded state and a folded state relative to the main ruler, and when the reference ruler is in the unfolded state, the reference ruler is perpendicular to the main ruler in the length direction. In a folded state, the reference ruler and the main ruler are consistent in length direction. The movable ruler can be switched between an unfolded state and a folded state relative to the main ruler, when the movable ruler is in the unfolded state, the movable ruler is connected to the guide rail through matching of the sliding piece and the guide rail, and the length directions of the movable ruler and the main ruler can be perpendicular through the limiting piece. The movable ruler can move relative to the main ruler along the length direction of the main ruler. In a folded state, the length directions of the movable ruler and the main ruler are consistent. A worker can accurately read the GAP value of the wheel eyebrow, the GAP value of the wheel eyebrow of the automobile is measured through the measuring tool, and the measuring tool has the advantages of being high in working efficiency, small in occupied resource and small in measuring error.
[007] Publication No. EP0922927 relates to device for measuring the bottom of vehicles comprising an extendable ruler that in one end with a pointed mandrel for contact with measuring holes or points and that the ruler in its other end is provided with a magnetic fastening means and a centering means for centering the fastening means relative holes in the bottom. The centering means is a conical mandrel that against the force of a spring can be pushed into the fastening bracket.

[010] Publication No. EP0167681 relates to a tractor includes a hitch for pulling a ground-working implement. A hydraulic cylinder is extensible and retractable to lower and raise the implement. A control system senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position. Error signals are derived from the sensed wheel slip, engine speed and draft force and correspond set point signals. The error signals are combined into a composite or combined error signal. The larger of (a) the combined error signal and (b) a separately determined position error signal. Is selected and converted to a pulse width modulated valve control signal which is applied to a control valve which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal. Certain set point signals are derived from the corresponding parameter signals themselves.
[011] Publication No. CN113168535 relates to a ponding water depth determination method. The method comprises the steps: obtaining image information of a ponding road at a preset distance of a ponding region, then carrying out the analysis and processing of the image information to obtain the spatial position of a ponding edge, acquiring the road slope angle, determining the road position corresponding to the maximum water depth of the ponding area through a certain strategy, and finally determining the maximum ponding depth of the ponding area according to the spatial position of the ponding edge, the road slope angle and the road position corresponding to the maximum water depth. The terminal does not need to wade, the ponding depth of the ponding area is measured, and risks caused by wading of the terminal are avoided. The method can be used for aided driving and automatic driving. Furthermore, the method improves the ADAS capability of the terminal in automatic driving or auxiliary driving, and can be applied to the Internet of Vehicles, such as vehicle external connection V2X, inter-vehicle communication long term evolution technology LTE-V, vehicle-vehicle V2V and the like.
