Description

Technical Field

[0001] The present invention relates to the technical field of arresters, and in particular to a lifting type arrester and a lifting type arrester control system. Background Art

[0002] At present, parking lots usually manage parking spaces by setting ground stakes on the left and right sides of each parking space entrance and connecting movable iron chains between the two ground stakes for blocking. When a vehicle needs to enter, the on-site manager removes the iron chain. This management method is costly and inefficient. When multiple vehicles enter at the same time, it also increases the waiting time for vehicle drivers. Summary of the invention

[0018] Furthermore, the mounting seat is sleeved on the guide column via a linear bearing.

[0019] Furthermore, the lower ends of the two lifting barrier units are embedded in the ground, and a long strip groove is provided on the ground between the two lifting barrier units. When the two mounting seats move to the lower mounting plate, the barrier member connected between the two mounting seats is accommodated in the groove.

[0020] Furthermore, a circular groove is provided on the lower mounting plate corresponding to the lower end of the screw rod, and the lower end of the screw rod is embedded in the circular groove and rotates in the circular groove.

[0021] Furthermore, the blocking member is a long rod, a chain or a rope.

[0022] In a second aspect, the present invention provides a lifting arresting control system, which needs to provide the device described in the first aspect, including two lifting arresting control subsystems, wherein the two lifting arresting control subsystems are respectively connected to two lifting arresting units, and each lifting arresting control subsystem includes:

[0023] An MCU module, and a motor drive module, a radio frequency transceiver module, a power supply module, a reset module, a speed adjustment module, and a torque adjustment module respectively connected to the MCU module;

[0024] The MCU module is connected to the motor of the lifting type barrier unit through the motor driving module, and is used to drive the motor to operate through the motor driving module; the MCU module is also connected to the motor of the lifting type barrier unit through the three-phase Hall line, and is used to obtain the operating state of the motor through the three-phase Hall line;

[0025] The MCU modules of the two lifting arresting control subsystems are wirelessly connected through two radio frequency transceiver modules, and are used to send and synchronize the running status of the motor through the radio frequency transceiver modules. The two MCU modules also receive control instructions of the remote controller through the radio frequency transceiver modules.

[0026] The power supply module is used to connect to a power source and transform the voltage to supply power to the MCU module;

[0027] The reset module is used to reset the MCU module;

[0028] The speed adjustment module is used to receive the speed setting value and transmit it to the MCU module;

[0029] The torque adjustment module is used to receive the torque setting value and transmit it to the MCU module.

[0030] Furthermore, each of the lifting arresting control subsystems further includes a third-party device signal input interface module, an electronic lock driving module, a spotlight driving module, and a status indicator light module connected to the MCU module;

[0031] The third-party device signal input interface module is used to process the signal input of the third-party device, and the third-party device includes: an access control system, an infrared sensor, and a card reader;

[0032] The electronic lock driving module is used to lock or unlock the screw nut of the lifting arresting device according to the instruction;

[0033] The spotlight driving module is used to drive the spotlight of the lifting arresting device;

[0034] The status indicator light module is used to indicate the working status of the lifting and lowering arresting device according to the setting of the enabling status indicator light.

[0035] Furthermore, the lifting control process of the lifting arresting control system is as follows:

[0036] Step 1: After the system is powered on, the MCU module kernel and interface are initialized, and then the RF module is initialized. Then the travel data, remote control code and the serial number data of the two lifting arresting units in the storage space of the MCU are read, and finally the arresting unit is lowered to the lowest point;

[0037] Step 2, the RF transceiver module monitors the remote control signal. When receiving the remote control signal, the MCU module determines whether the remote control code included in the remote control signal matches the remote control code in the storage space. If so, it proceeds to step 3. If not, it determines whether it is in the remote control learning mode. If so, it saves the remote control code in the remote control signal and then proceeds to step 3; if not, it proceeds to step 4.

[0038] Step 3, receiving the control instruction in the remote control signal, and then determining whether the control instruction is a lifting instruction, if it is a lifting instruction, entering the lifting sub-process, if not, entering step 4;

[0039] Step 4, determining whether the control instruction is a stop instruction, if it is a stop instruction, proceeding to step 5, if not, proceeding to step 6;

[0040] Step 5: Stop the drive and update the status;

[0041] Step 6: Determine the pressing status of the remote control. If it meets the preset conditions, enter the remote control learning mode. If it does not meet the preset conditions, the two MCUs exchange status through the RF transceiver module, then update the current status and return to step 2.

[0042] Furthermore, the abnormal state processing process of the lifting arresting control system is as follows:

[0043] Set the current detection point on the COM pin of the MCU module;

[0044] When the Hall state of the motor obtained through the three-phase Hall line is abnormal, and the value of the current detection point is abnormal, it is judged that the lifting and lowering blocking device is in a stalled state, and then it is further judged whether it is currently in the rising process. If it is in the rising process, the motor is driven to lower the blocking member, and then the state is sent to the other end; if it is not in the rising process, it is judged whether it is currently in the descending process. If it is in the descending process, the driving motor is stopped, and if it is not in the descending process, the motor driving module is turned off;

[0045] When the Hall state of the motor obtained through the three-phase Hall line is abnormal, but the value of the current detection point is normal, it is judged that the lifting and lowering arresting device is in a state of artificial violent hard pressing, and the Hall state of the motor is continuously obtained through the three-phase Hall line. When the Hall state is normal, the motor is driven to raise the arresting member.

[0046] The present invention has the following advantages:

[0047] 1. Through the operation of two motors, the lead screw nut is driven to move upward or downward with the forward or reverse rotation of the lead screw, thereby driving the blocking member arranged between the two mounting seats to move upward or downward. When the blocking member is located at the upper part, the management area is blocked to restrict the passage. When the blocking member is located at the bottom, the management area is released, thereby blocking or releasing the management area, saving time and labor costs;

[0048] 2. Use two MCU modules to drive the two motors to operate respectively through the motor drive module. At the same time, the two MCU modules send and synchronize the operating status of the motor through the RF transceiver module to achieve synchronous operation of the two lifting and blocking units connected to the blocking parts, avoiding the abnormal state that one end is raised and the other end is not raised, or one end is blocked while the other end continues to operate, thereby ensuring the normal operation of the lifting and blocking device.

[0064] See also Figures 1 to 4 As shown, the embodiment of the present invention discloses a lifting type blocking device, comprising: two lifting type blocking units 10 and a blocking member 20 connected between the two lifting type blocking units;

[0065] Each of the lifting arresting units 10 comprises:

[0066] Motor 101;

[0067] A planetary reducer 102, wherein an input end of the planetary reducer 102 is connected to the motor 101;

[0068] An upper mounting plate 103 is fixedly connected to the chassis of the planetary reducer 102;

[0069] A screw rod 104, the upper end of which is connected to the output end of the planetary reducer 102 and is perpendicular to the upper mounting plate 103;

[0070] The screw nut 105 is sleeved on the screw 104 and moves upward or downward as the screw 104 rotates in the forward or reverse direction;

[0071] A lower mounting plate 106 is disposed at the lower end of the screw rod 104 and is arranged parallel to the upper mounting plate 103;

[0072] A guide column 107 is vertically fixed between the upper mounting plate 103 and the lower mounting plate 106 and is arranged parallel to the screw rod 104;

[0073] At least one support column 108, fixed between the upper mounting plate 103 and the lower mounting plate 106;

[0074] The mounting seat 109 is sleeved on the guide column 107 and connected to the screw nut 105, and moves up and down synchronously with the screw nut 105;

[0075] The two ends of the blocking member 20 are respectively mounted on the mounting seats 109 of the two lifting blocking units 10 .

[0076] In a possible implementation, each of the lifting type blocking units 10 further includes a shell 110, the shell 110 having a downwardly open cavity and a side seam 1101, and the connection portion between the blocking member 20 and the mounting seat 109 is slidably disposed in the side seam 1101. The shell 110 can be engaged with an opening provided on the lower mounting plate 106 through a card slot at the bottom, thereby achieving positioning and fixing.

[0077] In a possible implementation, the mounting seat 109 is sleeved on the guide column 107 via a linear bearing 111. The linear bearing 111 can ensure that when the mounting seat 109 moves up and down along the guide column 107, no force in other directions is generated, thereby increasing the service life of the mounting seat 109.

[0078] In a possible implementation, the lower ends of the two lifting barrier units 10 are embedded in the ground, and a long strip groove 30 is provided on the ground between the two lifting barrier units 10. When the two mounting seats 106 are moved to the lower mounting plate 109, the barrier member 20 connected between the two mounting seats 109 is accommodated in the groove 30, so that the barrier member 20 is hidden in the groove 30, so that vehicles and the like will not be affected by the barrier member 20 when passing.

[0079] In a possible implementation, a circular groove (not shown) is provided on the lower mounting plate 106 corresponding to the lower end of the screw rod, and the lower end of the screw rod 104 is embedded in the circular groove and rotates in the circular groove.

[0080] In a possible implementation, the blocking member 20 is a long rod, a chain or a rope, and a suitable flexible or rigid blocking member can be selected according to the blocking requirements.

[0081] The working principle of the lifting arresting device is as follows:

[0082] Through the operation of two motors 101, the lead screw nut 105 is driven to move upward or downward as the lead screw 104 rotates in the forward or reverse direction, thereby driving the blocking member 20 arranged between the two mounting seats 109 to move upward or downward. When the blocking member 20 is located at the upper part, the management area is blocked to restrict the passage. When the blocking member 20 is located at the bottom, the management area is released, thereby realizing automatic blocking or releasing of the management area, saving time and labor costs.

[0083] The embodiment of the present invention further discloses a lifting arresting control system for controlling the lifting arresting device, including two lifting arresting control subsystems, wherein the two lifting arresting control subsystems are respectively connected to two lifting arresting units, and each lifting arresting control subsystem includes:

[0085] The MCU module is connected to the motor of the lifting barrier unit through the motor drive module, and is used to drive the motor to operate through the motor drive module; the MCU module is also connected to the motor of the lifting barrier unit through the three-phase Hall line, and is used to obtain the operating state of the motor through the three-phase Hall line; the motor of the lifting barrier device can be a brushed motor or a brushless motor, but because the brushless motor has a longer service life, a large torque and is relatively quiet during operation, Figure 5In the embodiment shown, a brushless motor is used, and the motor driving module also uses a brushless motor driving module that matches the brushless motor (if a brushed motor is used, the power supply of the brushed motor can be directly controlled by the MCU module to drive it); the MCU modules of the two lifting and arresting control subsystems are wirelessly connected through two radio frequency transceiver modules, which are used to send and synchronize the running status of the motor through the radio frequency transceiver modules, and the two MCU modules also receive control instructions of the remote controller through the radio frequency transceiver modules;

[0086] The power supply module is used to connect to a power source and transform the voltage to supply power to the MCU module;

[0087] The reset module is used to reset the MCU module;

[0088] The speed adjustment module is used to receive the speed setting value and transmit it to the MCU module;

[0089] The torque adjustment module is used to receive the torque setting value and transmit it to the MCU module.

[0090] Two MCU modules are used to drive the two motors to operate respectively through the motor drive module. At the same time, the two MCU modules send and synchronize the operating status of the motor through the RF transceiver module, so as to realize the synchronous operation of the two lifting arresting units connected to the arresting parts, avoiding the abnormal state that one end is raised and the other end is not raised, or one end continues to operate when a stall failure occurs, thereby ensuring the normal operation of the lifting arresting device.

[0091] In a preferred embodiment, each of the lifting arresting control subsystems further includes a third-party device signal input interface module, an electronic lock driving module, a spotlight driving module, and a status indicator light module connected to the MCU module;

[0092] The third-party device signal input interface module is used to process the signal input of the third-party device, and the third-party device includes: an access control system, an infrared sensor, and a card reader;

[0093] The electronic lock driving module is used to lock or unlock the screw nut of the lifting arresting device according to the instruction;

[0094] The spotlight driving module is used to drive the spotlight of the lifting type arresting device, and the spotlight can be used for specific logo display or local area lighting;

[0095] The status indicator light module is used to indicate the working status of the lifting and lowering barrier device according to the setting of the enabling status indicator light. When the barrier element rises or falls, the status indicator light flashes to remind nearby people to avoid it.

[0096] Through the above modules, the application scenarios of the lifting arresting device can be expanded to meet various usage needs.

[0097] like Figures 5 to 14 As shown, in a specific embodiment, the radio frequency transceiver module adopts a 433M wireless module, and the motor adopts a 24V DC brushless motor.

[0098] Figure 5 The schematic diagram of the module structure of the lifting arresting control subsystem in a specific embodiment (the whole control system consists of two sets of Figure 5 The subsystem shown in the figure) Figure 6 This is the overall block diagram of the lifting arresting control system; Figure 7 This is a single block diagram of a lifting arresting control subsystem; the lifting arresting control system receives remote control commands and third-party equipment input control commands, controls the DC brushless motor, pushes the lead screw through the planetary reducer, and thus drives the arresting member to move up and down, and realizes the following functions:

[0099] A. Receive 433M wireless remote control signals, decode and extract control instructions;

[0100] B. Through 433M wireless signal status interaction, the purpose of synchronizing both ends of the chain can be achieved;

[0101] C. Receive and process the Hall signal of the brushless motor;

[0104] F. Can receive signals from third-party devices such as ground sensors, infrared, and card readers;

[0105] G. Can be connected to spotlights and status indicator lights;

[0106] H. Can drive electric lock (normally closed / normally open);

[0107] I. Speed ​​and torque can be adjusted freely.

[0108] Among them, the design of the MCU module is as follows:

[0109] 1. Using ST Cortex-M3 main control CPU, multiplied to 72M;

[0110] 2. Initialization and application of 433M wireless module, switching of transceiver mode;

[0111] 3. Push-pull drive brushless DC motor to realize the functions of lifting, lowering and stopping, slow starting and stopping, and smooth operation;

[0112] 4. Both ends of the lifting chain are synchronized and share the same status, preventing the abnormal state where one end rises while the other end does not rise;

[0113] 5. Anti-blocking and anti-locking: when rising, the rotor will be blocked and when descending, when descending, the rotor will be blocked and stopped;

[0114] 6. Prevent human-induced violent pressure. When human-induced pressure is applied, it will naturally drop. When the person leaves, it will automatically rise.

[0115] 7. Overcurrent and overload protection;

[0118] 10. When lifting, drive the electric lock to lock the blocking part;

[0119] 11. Signal input from third-party equipment.

[0120] like Figure 8 As shown in the figure, the lifting control process of the lifting arresting control system is:

[0121] Step 1: After the system is powered on, the MCU module kernel and interface are initialized, and then the RF module is initialized. Then the travel data, remote control code and the serial number data of the two lifting arresting units in the storage space of the MCU are read, and finally the arresting unit is lowered to the lowest point;

[0122] Step 2, the RF transceiver module monitors the remote control signal. When receiving the remote control signal, the MCU module determines whether the remote control code included in the remote control signal matches the remote control code in the storage space. If so, it proceeds to step 3. If not, it determines whether it is in the remote control learning mode. If so, it saves the remote control code in the remote control signal and then proceeds to step 3; if not, it proceeds to step 4.

[0123] Step 3, receiving the control instruction in the remote control signal, and then determining whether the control instruction is a lifting instruction, if it is a lifting instruction, entering the lifting sub-process, if not, entering step 4;

[0124] Step 4, determining whether the control instruction is a stop instruction, if it is a stop instruction, proceeding to step 5, if not, proceeding to step 6;

[0125] Step 5: Stop the drive and update the status;

[0126] Step 6: Determine the pressing status of the remote control. If it meets the preset conditions, enter the remote control learning mode. If it does not meet the preset conditions, the two MCUs exchange status through the RF transceiver module, then update the current status and return to step 2.

[0127] like Fig. 9 As shown, the lifting and lowering sub-process specifically includes:

[0128] Step 31, the MCU module obtains the speed value from the speed regulation module and obtains the torque value from the torque regulation module;

[0129] Step 32, the MCU module reads the Hall count and calculates the stroke;

[0130] Step 33, the MCU module drives the motor through the motor drive module according to the acquired speed value and torque value;

[0131] Step 34, the MCU module obtains the running status of the motor through the three-phase Hall line;

[0132] Step 35, determine whether the Hall state changes, if so, count the number of turns, and exit the process when the number of turns reaches the stroke setting value, if not, stop and exit the process.

[0133] In a specific embodiment, the radio frequency transceiver module adopts a 433M wireless module (for example, a wireless module of model CMT2300):

[0134] In order to ensure data accuracy and completeness, the following communication protocol is formulated, using a question-and-answer method.

[0135] STX Data length Instruction number Serial Number Variable Data CRC 0xAA2DD4 1 byte 2 bytes 1 byte variable 1 byte

[0136] Response message:

[0137] Message Description

[0138] Instruction number

[0139] Response Code Description

[0140] Since a lifting and blocking device includes two lifting and blocking units, in order to prevent a third lifting and blocking unit from responding, a unique number of the lifting and blocking unit is added to the "variable data" field. This number can be entered during production and permanently stored in the flash storage space. Fig.10 As shown, the two lifting and arresting units can be paired through messages to prevent a third-party lifting and arresting unit from responding incorrectly.

[0141] like Fig.11 As shown, in order for the lifting and arresting units at both ends to be raised or lowered, or stopped synchronously, before starting the operation at one end, the status is sent through the RF transceiver module to enable the other party, and it is started after the other party responds. In order to ensure that the other party can receive accurately, the signal is sent three frames in a row. After the other party receives the data, it responds with a delay of 100ms (three frames of delay) to prevent channel conflicts. The two lifting and arresting control subsystems can determine the initiator of the operation (for example, the one with a larger number) by the number of the lifting and arresting units they control. When the initiator is abnormal, the other lifting and arresting control subsystem will naturally change to the initiator after receiving the status of the other party, and will not change again until the fault is eliminated.

[0142] Considering that the lifting arresting device may have abnormal conditions during operation (such as stalling, overcurrent or overload), it is necessary to identify and handle the abnormal conditions:

[0143] 1. Hardware

[0144] like Fig.12 As shown, a current detection point is set at the COM pin of the MCU module; when it is determined that the current at the current detection point exceeds the threshold, it takes effect, otherwise it is ignored.

[0145] Usually the current threshold is a fixed value: for example:

[0146] When starting to rise, it is 5A;

[0147] When rising steadily, it is 3A;

[0148] When starting to drop, it is 3A;

[0149] When it is falling steadily, it is 1A;

[0150] Therefore, when the current exceeds 5A, it can be regarded as a stall.

[0151] 2. Software:

[0152] A. An abnormal state descent is detected during the ascent process;

[0153] B. Stop when abnormal condition is detected during descent;

[0154] C. When an abnormality is detected during the stop process, the driver chip is turned off and the indicator light flashes;

[0155] D. Notify the other end to stop synchronization via 433M signal.

[0156] If the Hall state of the motor obtained through the three-phase Hall line is abnormal and the value of the current detection point is abnormal, it is determined that the lifting arresting device is in a stalled state, and then the execution Fig.13 The process shown further determines whether it is currently in the ascending process. If it is in the ascending process, the motor is driven to lower the blocking member, and then the status is sent to the other end; if it is not in the ascending process, it is determined whether it is currently in the descending process. If it is in the descending process, the driving motor is stopped; if it is not in the descending process, the motor driving module is turned off;

[0157] When the Hall state of the motor obtained through the three-phase Hall line is abnormal, but the value of the current detection point is normal, it is judged that the lifting arresting device is in a state of artificial violent hard pressing, and then the execution Fig.14 The process shown continuously obtains the Hall state of the motor through the three-phase Hall line. When the Hall state is normal, the motor is driven to raise the barrier, thereby preventing human-induced violent pressure. When human-induced violent pressure is applied, the barrier naturally descends, and when the person leaves, the barrier automatically rises.

[0158] The embodiment of the present invention drives the lead screw nut to move upward or downward as the lead screw rotates in the forward or reverse direction through the operation of two motors, thereby driving the blocking member arranged between the two mounting seats to move upward or downward. When the blocking member is located at the upper part, the management area is blocked to restrict passage; when the blocking member is located at the bottom, the management area is released, thereby blocking or releasing the management area, saving time and labor costs. Two MCU modules are used to drive the two motors to operate respectively through the motor driving module. At the same time, the two MCU modules transmit and synchronize the operation status of the motors through the radio frequency transceiver module, thereby realizing the synchronous operation of the two lifting and blocking units connected to the blocking member, avoiding the abnormal state that one end is lifted and the other end is not lifted, or the abnormal state that one end continues to operate when a stall occurs, thereby ensuring the normal operation of the lifting and blocking device.

[0159] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
