Chapter 1 Introduction 1.1 System Device Description scale ruler precise positioning system includes a ground electrical cabinet (including scale analyzers, etc.), an onboard electrical cabinet (including scale generation instrument, etc.), and a vernier scale ruler pointers. Scale ruler which is made of PVC wire flat synthetic material shell material and the internal laws of the preparation according to Gray code structure, similar to a graduated scale, usually installed in the locomotive moving along the side of a single orbit, or laying along the running track On the ground, or will be installed on the fence post beside the track can be, how long it needs to detect displacement laying on how long scale ruler; vernier pointer mounted on the locomotive, a location where the identification of the locomotive. Vernier scale ruler pointer relative movement parallel non-contact, vernier scale that is a pointer to the current position value, you can get the amount of displacement in the car or on the ground, without the initial reference point, positioning accuracy 5 mm, 2 mm resolution; can break continuous or continuous detection, especially for rail carts or uneven mechanical displacement detection circular motion. Waterproof, oil, dust, acid, used in metallurgy, mining, water, port yard, warehousing, chemical and other conditions are harsh environments. 1.2 System Components 1) automotive subsystems: the vernier pointer, automotive electrical cabinet (containing scale generation device, the switching power supply, etc.). 2) ground subsystems: the ground electrical cabinets (containing scale analyzer, switching power supplies, gateways, rulers lead converters, etc.). 3) scale ruler subsystems: the special scale ruler, CN box, EN boxes, cables and a variety of ordinary ruler for scale installation, fixed, protection agencies.

Chapter 2 System Principles scale ruler precise positioning system uses electromagnetic induction principle to detect the amount of displacement of the mobile device, when vernier pointer coil pass into alternating current, in the vicinity of vernier pointer produces an alternating magnetic field. Approximate scale ruler in an alternating magnetic field evenly distributed, each of scale ruler wire will be induced electromotive force. Scale instrument signal to generate the scale ruler induced by electromagnetic coupling loop. Scale analyzer signal received phase comparison. Signal phase with the phase of the signal line intersecting parallel lines of the same address is "0"; cross-line phase of the signal phase of the signal lines opposite and parallel to, the address is "1", so that the induction of the Gray code address information is arranged, whereby determine the position of the pointer on the vernier scale ruler in the longitudinal direction. After Chapter 3 System Features system scale generation instrument (and function signal generator) address of the carrier signal emitted by a certain period, the vernier scale ruler pointer to launch, scale analyzer ground station receives the signal, decode restore the absolute address at the scale ruler locomotive which, after processing the output controller by RS232 or RS485. Wear-free non-contact position sensing, long life; can be intermittent or continuous testing, ranging up to 2 km, the length of the displacement detection can be customized; resistant to pollution super capacity, available water, Steam, resistance pH; easy to install and replace (without changing the environment of the scene), maintenance-free; high stability, high reliability, multi-signal output mode selection; with reverse polarity protection, anti-lightning, anti-RF interference, anti-static ; no displacement of the absolute output reference point, not afraid brownout; sampling and measuring the length of time the location does not matter; can be used in circular motion mechanical position detection. Scale ruler can be buried in the concrete floor, easy installation and protection, without affecting the working environment. Chapter 4 System main application areas for bulk material handling environments material handling equipment. Systems such as mining, metallurgical, port systems, chemical systems, shipbuilding systems, power systems, cement systems, railroad systems, light systems, building systems, military systems, petroleum systems, mechanical systems, rail transportation equipment and automatic precise positioning control, such as: such as: ring furnace heating point, ring cold car positioning (silicon steel, sinter plant); unloading car location (mine, sinter, pellets, raw materials, coking, iron, port, lime); Crane Positioning (cold-rolled, hot-rolled, cut library, library slab, coil library, finished products, raw material warehouse, garbage power plant, pot luck submerged arc furnace plant material, garbage power plant); push car puller moved wagon Positioning (dumper); ship launching position (shipyard comb slide winch synchronous control); bucket wheel stacker reclaimer anti-collision position (raw materials plant, port); door positioning, loading and unloading boats Positioning (ports, hydropower); high-speed rail system 500 m long rail operation; other mobile devices rail precise positioning and centralized control. Chapter 5 System Installation and Checkpoints section 5.1 vernier vernier pointer pointer shape is flat plastic box mounted on top of an extension rod locomotive, close to the neighborhood scale ruler. When the locomotive forward, vernier pointer will move parallel along the scale ruler. Vernier locomotive address pointer is a pointer to measure the image, so when the system operation and maintenance, we must ensure that installation firm, let vernier scale ruler pointer out of the plane and remain at a distance of 50-150mm. Do occur when moving collisions with other objects. Section 5.2 scale ruler scale ruler subsystem includes scale ruler, mounting brackets, tensioning device, junction boxes, and various cables. As shown, the A welding fixture on the stationary object (which can also be saved without welding), jig B (corner angle) can be directly soldered or fixed objects and fixtures A connection to ensure a vertical horizontal line, but do not clamp D the jig and fixture C B as illustrated below a good connection, and then embed scale ruler, along with the upper clamp C connection is good, all the fixtures are installed in accordance with this model. Scale ruler is made by several groups in accordance with a special cable series around methods. Parallel installed near the orbit locomotives. In the process of moving locomotive, locomotives pointer vernier scale ruler forward or backward along the direction in accordance with a certain distance. Scale ruler is a key component of the system address detection, which is the standard measurement ruler address detection, so be especially careful during installation and maintenance, does not allow internally generated disconnection is not allowed to generate dynamic stretching and compression. Chapter 6 6.1 operating system maintenance procedures Note 1) general operator will be allowed to turn the power off and exit the system equipment, 2) strict compliance system mobile inspection system should be 3) vehicle idle be turned off, 4) is strictly prohibited in the cabinet Other electrical equipment plugged and placed debris, 5) non-hot plug system charged for repair or modules, 6) to prevent collision with hard objects and vernier scale ruler cable pointer. 7) Check the power supply is correct. 6.2 Routine maintenance 1) the integrity of the scale ruler cable firm checks, 2) check the firmness and the position of vernier pointer 3) Check the distance vernier scale pointer and scale rubber flat cable, 4) in the vertical direction to scale vernier scale cable located above the appropriate pointers, vernier pointer securely without loosening. With the movement of locomotives, vernier pointer does not collide with any object, 5) on-board electrical cabinet should regularly check their firmness, solidity check all the terminals, 6) power detection, normal: DC 5V ± 0.5V; ± 12V ± 0.5V. 7) Try to each vehicle control cabinet controlled power supply connected to the console (or backup cycle, the device can break), cut off the power supply when not in use. 8) should pay attention to the heat of the cabinet, to prevent the control cabinet is over baking. 9) should always be on the inside of each car rack terminals for cleaning. Not dust accumulation on the terminal strip on the internal modules and.
