Description

Berth lock undoes the lock system automatically

Technical field

The utility model relates to parking apparatus field, is specifically related to a kind of berth lock and automatically undoes the lock system.

Background technology

There is numerous electric vehicle position lock on the market at present, when car owner drives to leave, all need by remote controller or other means, berth lock to be undone the lock (rise), play parking stall management and control, others can not take the object of parking stall; Therefore for very inconvenient the master of parking stall, both wasted time, again because often forget that the berth lock that undoes the lock does not rise and causes parking stall to be taken situation by others.

Utility model content

The utility model, for the deficiencies in the prior art, proposes a kind of structure simple, easy to operate, and automatically can to undo the lock system detecting the berth lock automatically rising berth lock after vehicle leaves, concrete technical scheme is as follows:

A kind of berth lock undoes the lock system automatically, be provided with controller (1), the input of this controller (1) is connected with range sensor (3) through control circuit (2), and output is connected with elevating mechanism (4);

Described control circuit (2) comprises power supply chip U1 and power supply chip U2, described power supply chip U1 is all connected with power positive end with the anode of power supply chip U2, the equal ground connection of negative terminal, the output of wherein said power supply chip U1 is connected with the power positive end of described range sensor (3), control end is connected with the control end of described controller (1), be connected with the input of described controller (1) after output series resistor R7 with R6 of described power supply chip U2, the output of described range sensor (3) is connected between described resistance R7 and R6.

For better realizing the utility model, may further be:

The output of described range sensor (3) is normal open switch, and one end ground connection of this normal open switch.

Native system is such realization, the control end of controller (1) sends control signal, making its power supply chip U1 export 5V power supply is range sensor (3) power supply, when range sensor (3) detects that upper vehicle is left, send low level, or by output head grounding, the output of power supply chip U2 is 3.3V, when range sensor (3) sends low level or ground connection, to drag down the voltage of resistance R6 end, now, controller (1) detects low level, this sends control signal, opens berth lock.

The beneficial effects of the utility model are: native system structure is simple, utilizing infrared sensor to detect, parking stall locks vehicle parks situation, just automatically rises berth lock detecting, control simple after vehicle leaves, and can effectively prevent user from leaking operation, make its parking stall occupied; When berth lock is in opening, power supply chip U1, not for range sensor is powered, effectively can save the energy.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

As shown in Figure 1: a kind of berth lock undoes the lock system automatically, being provided with controller 1 should, this controller 1 is single-chip microcomputer, the input of controller 1 is connected with range sensor 3 through control circuit 2, output is connected with elevating mechanism 4, wherein range sensor 3 is infrared ray sensor, or is ultrasonic sensor;

As shown in Figure 2: described control circuit 2 comprises power supply chip U1 and power supply chip U2, be connected with the anode of battery after the positive power source terminal serial connection protective tube of described power supply chip U1, after the anode series diode D1 of power supply chip U2, the positive supply of battery is connected, power supply chip U1 and the equal ground connection of power supply chip U2 negative terminal, be connected with the power positive end of described range sensor 3 after the output series resistor R10 of wherein said power supply chip U1, control end is connected with the control end of described controller 1, be connected with the input of described controller 1 after output series resistor R7 with R6 of described power supply chip U2, resistance R3 and resistance R4 is also connected with between this resistance R7 and R6, the other end of this resistance R3 is connected with the output of power supply chip U1, the other end ground connection of resistance R4, the output of described range sensor 3 is connected between described resistance R7 and R6, the output of this range sensor 3 is normal open switch, when having vehicle above range sensor 3 detects, normal open switch closes, and ground connection.

As shown in Figure 3: berth lock undoes the lock the control method of system automatically, adopts following steps,

Step one: initial state;

Step 2: detect parking stall lock status, unlocking condition then gets back to step one, and blocking then enters step 3;

Step 3: time delay one minute

Step 4: open range sensor and power;

Step 5: time delay 10ms;

Step 6: detecting distance sensor output level;

Step 7: time delay 1ms;

Step 8: detecting distance sensor level;

Step 9: circulate 5 step 8, detects number of times and does not reach, then enter step 7, reach, then enter step 10;

Step 10: judge low and high level, is not low level entirely, then enters step 3, be low level entirely, then enter step 11;

Step 11: exit circulation, sends and opens parking stall lock signal;

Step 12: enter step one.
