Detailed Description
The invention provides a vehicle locking and unlocking control method of a brake lock, and the invention is further described in detail below in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
A locking and unlocking control method of a brake lock is shown in figure 1, and the brake lock comprises a brake device, a motor gear box 1 with a worm gear, a fixed arm 2, a winding shaft 3, a locking wire 4 and a circuit board 9, wherein the brake device can be an expansion brake, a band-type brake, a roller brake, a pincerlike brake, a disc brake and the like. The winding reel 3 and the motor gear box 1 with the worm gear are arranged on the fixing arm 2, the motor gear box 1 with the worm gear drives the winding reel to rotate, namely, the winding reel 3 is connected with the worm gear rod end of the motor gear box 1, the brake device comprises a brake cable 15 and a brake swing arm 5 which are used for controlling braking, and the brake cable 15 is tensioned or loosened to drive the brake swing arm 5 to control the braking or finish. Specifically, one end of a locking wire 4 is fixed on a brake swing arm 5 of a brake device, a brake wire 15 is connected to the free end of the brake swing arm 5, the other end of the locking wire 4 is wound on a winding shaft 3, a circuit board 9 is connected with a motor gear box with a worm gear and controls the motor gear box 1 with the worm gear, wherein the circuit board 9 can be connected with a power supply and an external power supply, the motor gear box 1 is controlled by the circuit board 9 to drive the winding shaft 3 to rotate to drive the locking wire 4 to be tensioned to the brake device to be locked and continue, the locking function can be realized, the motor gear box 1 is controlled by the circuit board 9 to drive the winding shaft 3 to reversely rotate to drive the locking wire 4 to be loosened to the brake device to realize unlocking, and preferably, the motor gear box 1 with the worm gear has the locking function.
Specifically, brake equipment is the floodgate that rises, brake equipment still includes brake cam 10, brake disc 11 and the brake block 12 that meets with brake swing arm 5, because brake swing arm 5's free end is connected with brake cable 15, when brake cable 15 or lock line 4 were taut, brake swing arm 5 drove brake cam 10 and rotates, and brake cam 10 promotes brake block 12, makes the brake block open, and brake block 12 rubs with 11 inner walls of brake disc mutually, makes the brake disc not rotate, realizes braking and lock car function.
The method for controlling locking and unlocking of the brake station, as shown in fig. 2, specifically comprises the following steps:
s1, when a vehicle locking instruction is received, the circuit board controls a vehicle locking line to contract for a preset length by controlling the forward rotation of a motor gear box with a worm gear, so that vehicle locking is realized;
and S2, when an unlocking instruction is received, the circuit board controls the car locking line to extend for a preset length by controlling the reverse rotation of the motor gear box with the worm gear to realize unlocking.
According to the brake lock, the circuit board controls and controls the motor in the motor gear box to rotate forwards and backwards, the rotation of the motor can realize the stretching of the locking line through the transmission structures such as the turbine worm, the winding shaft and the like, so that unlocking and locking are realized, and the locking and unlocking operations of the brake lock are accurately controlled.
Preferably, the winding shaft 3 is provided with a magnetic induction wheel 6, a multi-pole magnetic ring 7 is embedded on the outer circumferential surface of the magnetic induction wheel, a hall switch 8 for inducing the magnetic field change of the multi-pole magnetic ring 7 is arranged beside the magnetic induction wheel 6, the hall switch 8 is connected with a circuit board 9, the hall switch 8 generates high and low level signals when inducing the magnetic field change, the high and low level signals are counted to identify the number of rotation turns of the motor in the motor gearbox, and then the telescopic length of the locking line is obtained through the change of the number of the rotation turns of the motor. Because the motor can drive the multipolar magnetic ring embedded on the winding shaft to rotate when rotating, so as to generate alternate magnetic field change, NS alternate magnetic field change is received on the Hall switch induction surface, thus the Hall switch outputs pulse waveforms of high and low level change corresponding to the rotating speed of the rotor, then the circuit board counts the high and low level switching to realize the identification of corresponding motor rotating circle number, the outer circumference of the winding shaft is relatively fixed, and the telescopic length of the locking line can be obtained through the change of the motor circle number.
In order to better realize the detection of the brake lock fault, and simultaneously consider the abrasion of a brake device and the deformation of a brake cable, an appointed number-of-turns range of motor rotation needs to be preset, if the number of the motor rotation turns does not reach the appointed number-of-turns range, the motor is locked, or the number of the motor rotation turns exceeds the appointed number-of-turns range, the motor is controlled to stop rotating, and the fault is reported.
Because whether the brake lock is locked or not is directly related to the tension of a lock line, and the rotating speed of the motor is in inverse proportion to the tension, the rotation of the motor is controlled or stopped to lock the brake lock by detecting the rotating speed of the motor, so that the aim of identifying whether the motor rotates for a preset number of turns or not can be indirectly achieved by monitoring the rotating speed of the motor, and the rotating speed of the motor can be obtained by timing high and low levels. More preferably, in the method for controlling locking and unlocking of the brake lock, when a vehicle locking command is received, firstly collecting the current power voltage, calculating the difference value between the current power voltage and the maximum power voltage, then obtaining a first rotating speed compensation value according to the positive correlation relation between the rotating speed and the voltage of the motor, compensating the appointed rotating speed of the locked vehicle (namely judging the rotating speed of the motor for locking the vehicle) by using the first rotating speed compensation value, starting to drive the motor to rotate towards the direction of locking the vehicle, timing high and low level signals generated by the Hall switch by the circuit board, calculating to obtain the rotation speed of the motor, detecting the minimum value exceeding the appointed range of turns, continuing to rotate the motor, entering a deceleration stage, when the motor is decelerated to the appointed speed compensated by the speed compensation value, namely the corresponding vehicle locking pulling force is reached, the vehicle locking state is indicated, and the motor is controlled to stop rotating so as to complete vehicle locking.
Specifically, during driving, the current voltage value collected for the driving voltage is CV, the maximum voltage value is preset as MV, and the compensation coefficient obtained through repeated actual measurement is K. According to the mechanical momentum formula F t = v m, wherein F represents force, t represents time, v represents velocity, and m represents load magnitude. Since the brake lock stroke S is the same, S = v × t, F = (MV × v)/S is substituted, and thus the compensated tensile force is calculated as F = (MV × v)/S + (MV-CV) K.
Further, considering that the rotation speed of the motor is not only in positive correlation with the voltage but also in inverse proportion to various resistances of the transmission mechanism, in order to accurately detect the rotation speed of the motor, in the method for controlling locking and unlocking of the brake lock, when a locking instruction is received, a circuit board is used for timing high and low level signals generated by a Hall switch, and the rotation speed of the motor is calculated, the motor in the device does not immediately enter a folding brake device after being started, and enters a relative uniform speed AV stage with small speed change for a short time, the stage can be influenced by the friction force and the voltage of the transmission device, the average rotation speed can reflect the change of the voltage and the resistance when the motor starts to rotate to a preset number of turns and the average rotation speed in the process is calculated, a second rotation speed compensation value can be calculated according to the average rotation speed, the second rotation speed compensation value is used for compensating the appointed rotation speed of locking the vehicle, when the motor continues to rotate after rotating at a section of relatively high uniform speed and enters the folding brake device, the rotating speed of the motor is slowly reduced, corresponding compensation can be performed through AV in the uniform speed stage, when the motor is decelerated to a locked vehicle appointed rotating speed compensated by a second rotating speed compensation value, namely the corresponding vehicle locking pulling force is reached, the vehicle locking state is indicated, and the motor is controlled to stop rotating so as to complete vehicle locking.
Specifically, according to the formula of mechanical momentum F × t = v × m, where F denotes force, t denotes time, v denotes velocity, and m denotes load size. And because the brake lock strokes S are the same, S = v × t is substituted into F = (MV × v)/S, and the compensated tension F = (MV × v)/S + (MV-AV) K is calculated, wherein MV is the maximum average speed of the appointed relative average speed stage, AV is the measured average speed of the relative average speed stage, v is the measured speed, m is the load size, and K is the compensation coefficient obtained by repeated measurement.
Preferably, in the driving process, if the rotating speed of the motor is lower than the appointed rotating speed for locking the vehicle when the rotating number of turns of the motor does not reach the appointed number range, or the rotating number of turns of the motor exceeds the appointed number range, the motor is controlled to stop rotating, and a fault is reported.
In addition, the invention can also carry out braking through the locking line, and the braking state specifically comprises a half locking state and a slow braking state.
The semi-locking state is an incomplete braking state and is in a stage with certain resistance. The circuit board drives the motor to orbit in the direction of locking the vehicle through the motor driving circuit, and the circuit board times and counts high and low level signals generated by the Hall switch to calculate the rotating speed of the motor; meanwhile, when the motor is monitored to rotate for a preset number of turns after the motor starts to rotate, the average rotating speed in the process is calculated, a second rotating speed compensation value is calculated according to the average rotating speed, and the half-locking appointed rotating speed is compensated by the second rotating speed compensation value; when the motor is decelerated to the half-locking appointed rotating speed after the compensation of the second rotating speed compensation value (obviously, the half-locking appointed rotating speed before the compensation is higher than the locking appointed rotating speed before the compensation), the motor is controlled to stop rotating to complete half-locking, and the state of entering the half-locking state is indicated. In the driving process of the semi-brake state, if the rotating speed of the motor is lower than the locking appointed rotating speed (namely the rotating speed is slow due to the fact that the rotating force is large or the rotating is blocked) when the rotating number of the motor does not reach the appointed number range, or the rotating number of the motor exceeds the appointed number range, the motor is controlled to stop rotating, and faults are reported.
The slow braking state means that the braking time is prolonged in a staged and pause mode in the braking process. And the motor driving circuit drives the motor to orbit in the vehicle locking direction, the driving is stopped after the appointed uniform speed revolution n is obtained, the compensated tension is calculated, and the vehicle is switched to a deceleration mode. In the deceleration mode, after a certain time, the motor continues to rotate, and after the number m of revolutions is reached, the motor continues to stop for a certain time, and then continues to rotate in this way. In the deceleration mode, when the motor speed is detected to be lower than the agreed compensated slow brake speed, namely the compensated pulling force, the motor is stopped to rotate, and the slow brake state is indicated to be entered. In the driving process of the slow brake state, if the rotating speed of the motor is lower than the locking appointed rotating speed (namely the rotating speed is slow due to the fact that the rotating speed is large or is blocked) when the rotating number of the motor does not reach the appointed number range, or the rotating number of the motor exceeds the appointed number range, the motor is controlled to stop rotating, and a fault is reported.
In summary, through the structural design, the brake and lock functions can be simultaneously realized through one structure, the lock is realized by controlling the forward rotation of the motor gear box with the worm gear and the worm gear to control the lock wire to contract for a preset length through the circuit board, and the unlock is realized by controlling the reverse rotation of the motor gear box with the worm gear and the worm gear to control the lock wire to extend for a preset length through the circuit board, so that the operation of accurately controlling the lock and the unlock of the brake lock is achieved, and the problems that the lock control method of the brake lock in the prior art is complex and the brake lock cannot be accurately controlled to lock the brake lock are solved.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
