Referring to fig. 1, an embodiment of the present invention provides a shared parking stall lock, which is used to establish a signal connection with a server and is controlled by the server to lock or unlock a corresponding parking stall. Specifically, the parking stall lock includes: the lock comprises a seat body, a driving mechanism, a lock body and a main control module.
The pedestal sets firmly on corresponding the subaerial of parking stall, actuating mechanism and host system all locate in the pedestal.
The drive mechanism includes a motor that outputs rotational motion.
The lock body comprises a first arm and a second arm which extend out of the seat body and are connected into a whole, the first arm is connected with the output end of the driving mechanism in a rotation stopping mode and rotates along an axis parallel to the ground, and therefore the second arm is correspondingly lifted or lowered relative to the ground. In this embodiment, the number of the first arms is two, and the second arm is provided between the two first arms, so that the first arms and the second arms form a substantially door-shaped configuration.
It goes without saying that the second arm has a height when raised which is higher than the vehicle's chassis height and a height when lowered which is lower than the vehicle's chassis height.
The main control module is electrically connected with the motor and is in signal connection with the server, so that when the parking garage works normally, the main control module receives a locking instruction sent by the server and controls the motor to rotate forwards to lift the second arm, so that the parking space is locked and is prevented from being occupied randomly; the motor is controlled to rotate reversely to enable the second arm to descend so as to allow the vehicle to drive in and occupy.
Particularly, aiming at the defect that the parking space state existing in the existing shared bicycle management system due to communication or sensing faults cannot be matched with the actual occupied state, the parking space lock provided by the embodiment of the invention has the following configuration so as to improve the defect.
The parking spot lock further comprises a current sensor which is arranged in the seat body and electrically connected with the main control module, and the current sensor is used for detecting and sending a current signal of the parking spot lock when the motor acts, wherein the signal is a current value. And the main control module also receives the current signal when controlling the electric forward rotation to lift the second arm, controls the motor to rotate reversely to lower the second arm when judging that the current value exceeds a threshold value, and sends a first signal to the server.
Through carrying out above-mentioned configuration to the parking stall lock, can adopt current sensor to detect the current value of motor and exceed a threshold value and come the representation and have taken place the phenomenon of being hindered when the second arm lifts up the in-process. It should be understood that, in the normal action process of the parking lock, the lifting process of the second arm is a process with a very high requirement on the stability of each communication coordination mechanism in the shared parking space management system, and the blocking phenomenon occurring due to various factors in the process is often a main reason for causing the state of the parking lock of the server to be disordered. In this embodiment, the parking lock itself is provided with the current sensor, and when the lifting process of the second arm is blocked, the parking lock can send out the first signal to inform the server of the corresponding state change action, and the specific process of the parking lock is described in detail in the following method.
When the lifting is blocked, in order to reduce the possible damage to the lock body and the circuit part of the user vehicle and the parking spot lock, the main control module also controls the motor to rotate reversely so as to enable the second arm to descend. In addition, in this embodiment, the first arm is further provided with a spring to absorb and buffer the impact generated in the process when the second arm is blocked due to the impact on the shielding object.
Further, in order to detect the fault source as much as possible in the case where the above-described lifting process is hindered, the parking lock has the following configuration.
The lock body rests at least partially against the ground when the second arm is lowered, the part resting against the ground forming a ground-resting portion of the lock body.
Sharing parking stall lock still includes distance sensor, and it locates pastes ground portion and keeps away from the one side on ground when the second arm descends. The distance sensor is electrically connected with the main control module and used for detecting the reflection distance of the shielding object in the preset distance in the opposite direction.
The main control module sends a detection signal to the distance sensor to control the distance sensor to start detection when controlling the motor to rotate reversely so as to enable the second arm to descend, and sends a second signal to the server when judging that a shielding object exists in the preset distance.
The above embodiment introduces the distance sensor, and it has the characteristics of high stability and low false alarm rate, so that after the second arm descends again, the main control module accurately detects whether the shelter is actually present above the parking lock through the distance sensor, and sends a second signal according to the detection result to inform the server whether the corresponding trigger condition of the locking instruction sent by the server has a corresponding fault.
Correspondingly, the embodiment of the invention also provides a shared parking space management system which comprises a server, a shared parking space lock, a user terminal, a management terminal and a geomagnetic sensor, wherein the shared parking space lock, the user terminal, the management terminal and the geomagnetic sensor are all in signal connection with the server through the Internet. The shared parking spot lock adopts the technical scheme.
The user terminal is used for the user to send a reservation request and an arrival signal to the server. The reservation request is used for reserving the reserved parking space selected by the user, and the arrival signal is used for informing the server user of arriving at the reserved parking space.
The management terminal is used for receiving fault notification from the server by a manager of the parking lot.
The geomagnetic sensor is arranged in the middle of the corresponding parking space and is controlled to be started by an activation signal sent by the server so as to detect whether the vehicle on the parking space drives away or not, and a third signal is sent to the server when the vehicle is detected to drive away.
The server stores parking space states corresponding to the parking spaces, and correspondingly changes the parking space states according to the reservation request, the third signal and the first signal. The system also sends out the activation signal and an unlocking instruction according to the arrival signal, sends out the locking instruction according to the third signal and sends out a fault notification according to the second signal. The specific trigger conditions and trigger timing for the communication of the modules that make up the system are described in detail in the methods described below.
Based on the shared parking space management system, the embodiment of the invention also provides a status monitoring method for the reserved parking space, which completely presents the interaction process of each module in the system, and specifically comprises the following steps:
the user terminal sends the reservation request;
the server receives the reservation request and changes the corresponding parking space state into a non-reservation state;
the user terminal sends the arrival signal;
the server sends the unlocking instruction and the activation signal after receiving the arrival signal;
after receiving the unlocking instruction, the main control module of the shared parking spot lock controls the motor to rotate reversely so as to enable the second arm to descend;
the geomagnetic sensor starts detection after receiving the activation signal, and sends out the third signal when detecting that the vehicle drives away;
after receiving the third signal, the server sends the locking instruction and changes the parking space state into a reserved state;
after receiving the locking instruction, the main control module of the shared parking spot lock controls the motor to rotate forwards so as to lift the second arm; if the second arm is lifted to the right position, the monitoring process is finished; if the second arm is blocked from being lifted, the main control module sends the first signal and the detection signal;
after receiving the first signal, the server changes the corresponding parking space state into a non-reservation state;
the distance sensor of the shared parking spot lock starts detection after receiving the detection signal, and the main control module sends the second signal when judging that a shelter exists in the preset distance;
and after receiving the second signal, the server judges that the geomagnetic sensor has a fault and sends a fault notification to the management terminal.
In the state monitoring method, the server detects whether the user drives away from the parking space through the geomagnetic sensor so as to send out a locking instruction, and the detection accuracy of the geomagnetic sensor is greatly influenced by whether magnetic substances exist in the installation position and the surrounding environment, so that a certain false alarm rate exists in the detection process. According to the embodiment of the invention, the first signal is sent to inform the server when the parking space lock is in the locking process, namely the lifting process of the second arm is blocked, so that the server can change the parking space which is changed into the bookable state when the server receives the third signal originally into the non-bookable state again, thereby preventing the user from booking the parking space which is probably occupied actually or has a fault again, solving the problem of disordered parking space state of the parking space management system, improving the operation level of the parking lot as a whole and improving the quality of parking service.
In addition, after the second arm descends again, the main control module accurately detects whether a shelter really exists above the parking spot lock through the distance sensor, and if the shelter is detected, the geomagnetic sensor is indicated to generate false alarm, and then the second signal is sent out; if it is determined that the blocking object is not detected, it may be that the driving mechanism itself has failed, and a fourth signal is sent. The server judges the fault type according to the received signal and sends a fault notification to the management terminal, and a manager can quickly respond and arrange corresponding types of maintainers to carry out on-door maintenance.
The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the invention or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the invention.
