FIG. 1 is a block diagram of a management system 1 according to an embodiment of the present invention. Referring to FIG. 1 , the management system 1 includes (but is not limited to) one or more mechanical parking devices 30 , one or more backup power sources 50 , and an abnormality control device 100 . The management system 1 is suitable for parking lot management.

The mechanical parking device 30 may be a gate, a car compartment, a vehicle-mounted transfer tray, a rotary tray, a lift, a transporter, a charger, or other mechanical parking-related devices. The components of the mechanical parking device 30 may be power components such as a motor, a transmission chain, and a Programmable Logic Controller (PLC). Alternatively, the components may also be various types of mechanical components such as slide rails, turntables, screws, cylinders, power supplies, positioners, carriers, etc., but are not limited thereto.

The backup power source 50 may be an Uninterruptible Power System (UPS), a generator, or a battery. In one embodiment, the backup power source 50 may include a supercapacitor (or called an Electric Double-Layer Capacitor (EDLC)). The characteristics of supercapacitors are (compared with ordinary batteries) relatively long life and high tolerance to ambient temperature, so as to reduce the limitation of battery power due to cycle life. In other embodiments, the backup power source 50 may also include lithium batteries, graphene batteries, or other types of electrical storage elements. In addition, in one embodiment, the backup power source 50 is used to provide power to the mechanical parking equipment 30 and the abnormality control device 100 under set conditions (eg, power failure, earthquake, voltage instability, etc.).

The abnormality control device 100 may be a desktop computer, a notebook computer, an AIO computer, a smart phone, a tablet computer, or a server and other devices. The abnormality control device 100 may include (but is not limited to) a communication module 110 , a storage 130 and a processor 150 .

The communication module 110 may be a transceiver supporting Wi-Fi, mobile network, Bluetooth, Ethernet, fiber optic network or other types of communication protocols. In one embodiment, the communication module 110 is used to transmit information to an external device (eg, a computer, a server, or a mobile phone). In some embodiments, the message may be in the form of a text message, a network packet, a call, or other forms.

The storage 130 may be any type of fixed or removable random access memory (RAM), read only memory (ROM), flash memory, conventional hard disks (Hard Disk Drive, HDD), solid-state hard disk (Solid-State Drive, SSD), non-volatile (nonvolatile) memory or similar components. In one embodiment, the storage 130 is used to record code, software modules, configuration, data (eg, operating status, setting parameters, notification messages, etc.) or files.

The processor 150 is coupled to the communication module 110 and the storage 130. The processor 150 may be a central processing unit (CPU), a graphics processing unit (GPU), or other programmable general Purpose or special purpose microprocessor (Microprocessor), digital signal processor (Digital Signal Processor, DSP), programmable controller, Field Programmable Gate Array (Field Programmable Gate Array, FPGA), special application integrated Circuit (Application-Specific Integrated Circuit, ASIC), neural network accelerator or other similar elements or a combination of the above elements. In one embodiment, the processor 150 is used to execute all or part of the operations of the abnormality control device 100 , and can load and execute each code, software module, file and data recorded in the storage 130 .

In one embodiment, the abnormality control device 100 further provides an input-output (I/O) interface for connecting with the mechanical parking device 30 and transmitting data to and from the mechanical parking device 30 accordingly. For example, the abnormality control device 100 obtains the status report from the mechanical parking facility 30 . For another example, the abnormality control device 100 transmits an instruction or configuration setting of the mechanical parking device 30 . In some embodiments, the abnormality control device 100 (after being modularized) may be integrated into any mechanical parking device 30 .

Hereinafter, the method described in the embodiment of the present invention will be described in conjunction with various elements, modules and devices in the management system 1 . Each process of the method can be adjusted according to the implementation situation, and is not limited to this.

FIG. 2 is a flowchart of an abnormality control method according to an embodiment of the present invention. Referring to FIG. 2 , the processor 150 may record the operation state of the mechanical parking device 30 in the storage 130 (step S210 ). Specifically, the operating state is related to the operating relationship between the mechanical parking device 30 and the vehicle. The action relationship can be related to the current action or attitude, location and load situation. In one embodiment, the actuation relationship includes the positions of the components of the mechanical parking device 30 and the relative positions of the mechanical parking device 30 and the vehicle. Take the handling status as an example: whether the vehicle enters the field and sends it to the car compartment or the vehicle leaves the field to send the car; whether the car compartment has reached the location; whether the lift has reached the location; whether the transporter is carrying the vehicle; whether the entrance and exit are closed. It should be noted that, according to the structure and control items of each parking lot, the type and content of the operation state and the action relationship can be changed according to the actual needs.

The processor 150 may detect an abnormal condition of the mechanical parking device 30 (step S230). Specifically, abnormal conditions include power interruptions and shutdowns (or shutdowns). In one embodiment, the processor 150 may periodically query the power or system status of the mechanical parking device 30 via the input/output interface, or the mechanical parking device 30 may actively transmit the power or system status to the abnormality control device 100 . And when the report from the mechanical parking device 30 has not been received within the predetermined time, the processor 150 may regard it as the occurrence of an abnormal situation. In another embodiment, the processor 150 may directly detect the power of the mechanical parking device 30 via the detection circuit. For example, the detection circuit determines the operating voltage or current of the mechanical parking device 30, and regards the occurrence of an abnormal situation when the operating voltage or current is lower than a threshold value.

In some embodiments, the abnormal conditions may also be natural disasters, fires, high temperatures, power instability, and the like. The abnormality control device 100 can determine the abnormality through temperature, voltage, humidity or other types of sensors.

If no abnormal condition is detected, the processor 150 continuously updates the operation status of the mechanical parking device 30 .

In response to detecting an abnormal situation, the processor 150 can generate a notification message according to the operation state before the abnormal situation occurs, and transmit the notification message through the communication module 110 (step S250 ). Specifically, when an abnormal condition of the mechanical parking device 30 occurs, the processor 150 can generate a notification message in a form supported by the communication module 110 according to the last or more operation states of the mechanical parking device 30 . The selection of these operational states is based on the time closest to the occurrence of the abnormal situation. The abnormality control device 100 is still powered by the backup power source 50 or other power sources, so that the communication module 110 can send the notification message. In addition, the notification message can specify a specific email address, phone number, or network address as an exception notification, and let the outside world know the operating status before the exception occurs.

In one embodiment, in response to removing the abnormal situation, the processor 150 may control the mechanical parking device 30 to restore the operating relationship before the abnormal situation occurs. The exclusion of abnormal conditions may be the restoration of power, the normal operation of equipment, the removal of disaster alarms, or the value of sensors within the safe range. The processor 150 can send an instruction or provide an instruction to reconstruct the state information of the mechanical parking device 30 , so that the mechanical parking device 30 can know the operation relationship with the vehicle before the stop, and proceed to the next operation accordingly.

In one embodiment, the processor 150 further records the setting parameters of the mechanical parking device 30 in the storage 130 . This setting parameter is the configuration of the mechanical parking device 30 in the current operating state. Configurations can be related to modes, power characteristics or load conditions. The processor 150 will update the set parameters of the mechanical parking device 30 whenever the set parameters are changed. In addition, in response to detecting an abnormal situation, the processor 150 can generate a notification message according to the operating state and the setting parameters before the abnormal situation occurs. That is to say, in addition to the operating status, the processor 150 also integrates the last or more setting parameters before the abnormal situation occurs into a notification message. In this way, the processor 150 can send an instruction or provide an instruction to reconstruct the setting parameters of the mechanical parking device 30, so that the operation of the mechanical parking device 30 can be smoothly and safely connected to the operation before the power failure or other abnormal conditions occur in a timely and orderly manner. state.

In this way, remote maintenance personnel can grasp the status of the power outage site and find out the necessary countermeasures when the power is restored. In addition, after the power is restored, the system administrator and the remote maintenance and management personnel are notified to confirm that the state of the mechanical parking equipment 30 is safe and sound, and the system start-up warning light and whistle are issued on the facility site. After the on-site personnel clear the site, the mechanical parking equipment 30 will be restarted safely.

In order to ensure that the notification message is sent successfully, the processor 150 can transmit the notification message according to the working power and the operation period of the communication module 110 (which may include the period of analog-to-digital processing, power amplification, filtering, radiation electromagnetic wave, etc., but not limited thereto. ) to determine the required energy. For example, the required energy is the product of the operating power, the operation period and the capacity margin (Margin). Capacity headroom is related to additional capacity to avoid factors such as battery aging or other factors affecting operating power and duration of operation. For example, the capacity margin is 130%, 150% or 200%. The processor 150 can compare this required energy to the remaining energy. The remaining energy is the remaining energy of the backup power supply 50 , and the comparison result between the required energy and the remaining energy is related to the feasibility of transmitting the notification message through the communication module 110 . If the remaining energy is about to be lower than the required energy (eg, the difference is smaller than a safe range), the processor 150 may generate a notification message in advance according to the latest operating state and/or setting parameters, and transmit the notification message through the communication module 110 .

In one embodiment, the processor 150 may determine the attenuation index of the backup power supply 50 according to the attenuation rate and the capacity margin of the backup power supply 50 . The backup power source 50 includes a battery, and the decay rate is related to the number of charge-discharge cycles of the battery and the temperature of the environment where the backup power source is located. The battery state (State of Health, SoH) and the storage capacity (State of Charge, SoC) can be used as energy indicators of the energy storage system. The energy storage capacity of the battery will gradually decline with the number of charge-discharge cycles and the ambient temperature; the so-called Degradation rate. The attenuation index is used as a basis for judging battery replacement. If the product of the decay rate and the capacity margin is less than a critical value (eg, 90%, 110%, or 130%), it means that the actual capacity margin has reached the critical value, which may lead to insufficient power supply capacity of the UPS. For example, if the decay rate of the energy drops below 70%, and the capacity margin is set to 150%, the decay index is 150%*70%=105%. Assuming that the critical value is 110%, the attenuation index is already less than 110%. Therefore, the battery module should be replaced in time or the battery capacity should be expanded by connecting the batteries in parallel.

In this way, it can ensure that the transmission task of the complete notification message is not interrupted, and at the same time, it is environmentally friendly, that is, there is no environmental protection burden after the battery life is exhausted.

In addition to ensuring the transmission of notification messages, the backup power source 50 can also ensure that the mechanical parking device 30 is parked in a safe position after an abnormal situation occurs. In one embodiment, the processor 30 may determine the operating power and the operation period of the components of the mechanical parking apparatus 30 to move to the safe position. This operating power is the power consumed by the mechanical parking device 30 at maximum load (eg, maximum load or maximum rotational speed). It is worth noting that the mechanical parking equipment 30 may be subject to high heavy loads (eg, 2000~3000 kilograms (Kg)), high power motor drive and lift (to pull 3~6 vehicles, and the no-load/full-load power drop is as high as 10~ 20 tons or more), and carrying high-priced items. Therefore, when the mechanical parking device 30 is interrupted without warning or other abnormal conditions, the backup power supply 50 needs to provide sufficient total energy to assist the mechanical parking device 30 to still move to a safe position. The processor 150 can determine the total capacity of the backup power source 50 according to the operating power, the operation period and the capacity margin. For example, the total capacity of the backup power supply 50 is at least the product of the operating power of the motor under full load, the time required for the longest positioning (moving to a safe position) and the capacity margin. From this, it can be seen that the operation-related information of the mechanical parking equipment 30 can be used as a reference for the capacity planning of the backup power source 50 . If the on-site mechanical parking equipment 30 changes, the processor 150 needs to further determine whether to adjust the capacity of the backup power supply 50 . In this way, it can be ensured that the vehicle board and the transmission mechanism of the mechanical parking device 30 are properly parked in a stable and safe position, thereby ensuring that there is no safety concern when restarting after the power is restored.

To sum up, in the abnormality control device and abnormality control method for a parking lot according to the embodiment of the present invention, the power storage element has a relatively long service life and a high tolerance to ambient temperature, and it is ensured that a corresponding Notify messages and move the device to a safe location. In this way, the embodiment of the present invention can facilitate maintenance personnel to track records in time, so as to quickly find countermeasures for obstacle removal. In addition, the embodiments of the present invention can prevent the system from entering into a wrong action of starting after the operation is resumed, thereby endangering the parked vehicle or the on-site maintenance personnel.

Although the present invention has been disclosed above by the embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The protection scope of the present invention shall be determined by the scope of the appended patent application.
