Description

Patrol and examine the monitoring recording device

The utility model relates to a kind of induction type patrol record device of being made up of electron device, is applicable to that railway locomotive, circuit and all kinds of warehouse, goods yard etc. need regularly patrol and guard the place of inspection.

At present, the personnel of patrolling and examining such as night watchman, trackwalker, relevant skilled worker are carried out the equipment that the tours of inspection working condition exercises supervision, normally wired monitoring apparatus, this equipment are will be arranged on the switching device of checkpoint and indoor testing fixture couples together by lead.The checkpoint is many, then lead is just many, long for distance, not only cost height, and complex structure, and function is also poor.

The purpose of this utility model is the shortcoming that will overcome above-mentioned wire transmission mode monitoring apparatus, design a kind of do not have the lead transmission mode portable, patrol and examine the monitoring recording device that receiving trap that a sender unit and the personnel of patrolling and examining carry is formed jointly by ground, with reception and the storage of realization to information.This device can match with specific record display device, finishes the supervisory role to tours of inspection work jointly.

The purpose of this utility model can realize in the following manner.

Portable recorder I and fixed position sensor II are set, the two connects by induction mode, position sensor II is passive solid information part, register I is by the governor circuit 1 that is provided with single-chip microcomputer, link information receiving circuit 2, power sense circuit 3, the clock memory circuit 4 that can regularly start, sound cue circuit 5,

aura warning circuit

6,7 constitute respectively, register I is portable, and position sensor II is fixed.Message pick-up circuit 2 can be the magnetic induction device, also can be pickup coil; The passive solid information part that constitutes position sensor II can be the magnet steel coding structure, also can be the pickup coil structure; When it was the magnet steel coding structure, magnet steel positional number set in position sensor II was corresponding with the magnetic inductor number of packages in the message pick-up circuit 2, and n magnet steel position can have 2 ⁿThe coding of-a kind of combination then can establish 2 at most ⁿ-1 ground check point; When it is the pickup coil structure, in each inductor II, be provided with the different LC resonance coil of resonance frequency, corresponding with the pickup coil in the message pick-up circuit 2.In power sense circuit 3, be provided with boost, voltage stabilizing, undervoltage warning, feed circuit.

The utlity model has following advantage: portable patrol record device be arranged on the position sensor of patrolling and examining a little and be connected by way of electromagnetic induction, overcome the problem that transfer wire brings of laying, it is not subjected to the restriction in time, space, and volume is little in light weight, carry, use all and make things convenient for, components and parts adopt general part, thereby stable performance, not fragile, this device itself is simple in structure, but have the time limit, in proper order, receive, functions such as storage prompting, warning, be suitable for supervision to the work of patrolling and examining.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the register schematic appearance, 8-casing among the figure, 9-message pick-up induction end socket;

Fig. 2 is for patrolling and examining monitoring recording device circuit structured flowchart, I-register among the figure, 1-governor circuit in it, 2-message pick-up circuit, 3-power sense circuit, 4-clock memory circuit, 5-sound cue circuit, 6,7-aura warning circuit, II-position sensor;

Fig. 3 is the circuit theory diagrams of register one embodiment;

Fig. 4,5 is respectively that the magnet steel coding type position sensor structure that is provided with 3 magnet steel among the embodiment is analysed and observe, vertical view, 12-magnet steel among the figure, 13-filler, 14-housing.

In the present embodiment, sound cue circuit 5 is connected and composed by switching tube G1 and hummer M1; Aura

warning circuit

6,7 is connected and composed by the corresponding port of luminotron D1, D2 and governor circuit 1 respectively, main frame U1 in the governor circuit 1 adopts the PIC16C84 chip, chip U2 in the clock memory circuit 4 is PCF8583, chip U3 in the power sense circuit 3 is MAX856, adopts the switching regulator of N-channel MOS FET.

Now the position sensor with magnet steel coding structure formula is an example, and 3 magnet steel 12 can be set in the position sensor II in the present embodiment, can have 2 by the different of magnet steel quantity and ranking ³-1=7 kind combination, promptly it can satisfy and establishes 7 checkpoints on the ground at most.And the induction end of the message pick-up circuit 2 of corresponding patrol record device I also is equipped with 3 magnetic induction device S1, S2, S3, selects tongue tube in the present embodiment for use.

As personnel of patrolling and examining during with the induction end socket 9 insertion position inductor II of entrained register I, because magnetic induction device tongue tube S1, S2, S3 corresponding actions in the magnet steel effect message pick-up circuit 2, supposing has magnet steel on position 1, the position 3 in the inductor II of this checkpoint, 2 free time of position, dry-reed tube switch S1, S3 adhesive that this moment is corresponding, S2 keeps disconnecting, then port RB5, the RB7 of Dui Ying governor circuit 1 chips U1 are low level, port RB6 is a high level, judge that through governor circuit 1 positional information is distinguished.Information after host chip U1 confirms is carried out serial communication by port SDA, the SCL of the chip U2 of its port RA0, RA1 and clock memory circuit 4, read real-time clock, after chip U1 handles, deposit among the chip U2 by serial communication once more with corresponding format.Putting port RB3 simultaneously is low level, luminotron D1 conducting is lighted, send pulse signal about 2KHZ from port RA3, cause triode G1 with the same frequency conducting, close, AC signal in addition on hummer M1 promotes its sounding, carry out acousto-optic hint, represent register I operate as normal, receive the information of this checkpoint, so finish reception, the storage of primary information.

Have among the chip U2 of clock memory circuit 4 and regularly play noisy function, after finishing the patrolling and examining an of point, chip U1 can set a delay time, surpassing this time does not carry out next when patrolling and examining yet, chip U2 proposes interrupt request by port INT to chip U1, after the port RBO of chip U1 receives that look-at-me is confirmed, carry out acousto-optic hint, remind the personnel of patrolling and examining to be carried out in accordance with regulations and patrol and examine by its port RA3, RB3 control luminotron D1, hummer M1.

The chip U3 of power sense circuit 3 adopts the on-off mode voltage stabilizer of N-channel MOS FET, provides stable power voltage by automatic adjustment pulsed frequency to each circuit.The battery input voltage is connected to the port LBI of chip U3 after resistance R 9, R10 dividing potential drop, the reference voltage inner with it relatively, then export the chip U1 of a low level if the result is on the low side to governor circuit 1 by port LBO, it is low level that chip U1 puts port RA2, cause luminotron D2 to light, the prompting battery is under-voltage.
