Description

Combined control system and control flow of lifting and horizontal moving garage
Technical Field
The invention relates to the technical field of parking equipment, in particular to an improved lifting and horizontal moving garage combined control system and a control flow.
Background
Parking equipment (mechanical garage) in China is introduced from forty years ago, wherein the lifting and transverse moving garage is always a main corner, and the market share is not lower than 80%. Up to now, the control system of the lifting and horizontal moving garage adopts a PLC device, and the cost is relatively high. Over a decade ago, the industry has tried to construct a control system of a lifting and traversing garage by using a single chip microcomputer to replace a PLC device, but for various reasons, the control system cannot be applied (at least not applied to products) until now.
The technical scheme of the special control system for the lifting and horizontal moving type stereo garage, which is provided by the patent application with the publication number of CN200969049Y and the name of 'special control system for the lifting and horizontal moving type stereo garage' filed on 8.11.2006, provides a main controller, a slave controller and an operation box. From the related applications it is known that: the technical scheme is characterized in that the operation box is used as a human-computer interface device, information of accessing the vehicle is sent to the main controller in a card reading or keyboard input mode, and the garage running state information is displayed; the main controller is used as a core component to control a certain number of vehicle plates (namely support plates) and transverse frames (namely trays), the embodiment in the figure is used for controlling a two-layer 3-row lifting and transverse type stereo garage, the detection of the positions and the running states of the trays and the support plates and the operation of vehicle access are mainly finished, various photoelectric switches and travel switches are used for detecting the position states, and a contactor and a relay are used for executing start-stop control on a dragging motor. When the vehicle is stored and taken, the main controller can receive and analyze the instruction input by an operator at an operation box button or an upper computer, and make reasonable industrial control arrangement; judging the state of the detection element, and reading information of a mechanical driving part of the garage; then, the information is fed back to the executive component, the vehicle board is dragged, the position movement of the vehicle board is realized, and the access operation of the vehicle and the display of signals (indicator lights) are completed. The slave controller is used as a secondary control panel, when the number of the garages exceeds the control number of the master control panel (in the embodiment in the figure, the number of the garage columns exceeds 3 columns), the column expansion performance is provided, each slave chess control panel can control 1 column of garages, various collected limiting signals are transmitted to the master controller in a 485 communication mode, and the control signals of the master controller are received to execute corresponding operation.
As is well known, the PLC is used as a mature component, has perfect functions, is stable and reliable, has various forms, is matched with visual auxiliary programming software by each mainstream manufacturer, and is convenient to use. The single chip microcomputer is low in price and can flexibly adapt to various application occasions, but the design, the manufacture and the specialized programming of the circuit board are needed, so that the single chip microcomputer is more suitable for being used in a control device of a large-scale product.
Therefore, the main control chip of the control system of the lifting and transverse moving garage is changed from a PLC to a single chip microcomputer, and the key problems are as follows: firstly, how to balance the matching of the master structure and the slave structure so as to ensure that the cost is relatively low on the premise of ensuring the service performance; secondly, the structures of the master controller and the slave controller are generalized, and the garage with different configuration forms can be adapted; and thirdly, the control flow and the running software of the master controller and the slave controller are generalized, and can adapt to different configurations and different application scenes.
The above application documents do not basically introduce or make useful prompts to the generalization of the structures of the master controller and the slave controller and the generalization of the control flows and the operating software of the master controller and the slave controller, and the software flow chart shown in the attached drawings is not only simple, but also only carries the simplest control flow of the PLC control system. The number of the highest layers of the current mainstream products of the lifting and traversing garage is at least seven, the layout of the garage is limited or influenced by the environment and the position, the combination forms are very many, and the operation control mode of the vehicle plate is beyond the previous limit. For the control chip using the single chip microcomputer, if the control flow of the original PLC control system is limited, the complexity of the control system is increased by the master controller mode and the slave controller mode. Therefore, the above application documents have little reference to the structures, control flows and generalization of running software of the master controller and the slave controller which take the single chip microcomputer as a control chip. The master controller acts as a small, fully functional control device and then adding slave controllers in columns or layers adds substantial complexity to the control system and overall cost is not necessarily an advantage over PLC control systems.
The similar technical scheme also has a patent application which is filed on 21.12.2015, and has a publication number of CN105401770A and a name of 'a structural control system of lifting and horizontal moving parking equipment', and the key point of the technical scheme is that a control chip is a master control device of a single chip microcomputer and is responsible for being connected with peripheral devices and each secondary device; the number of the secondary devices of which the control chip is a singlechip is determined according to the number of all parking space units required to be controlled by the control system; each secondary device is respectively connected with the main control device through a serial port communication interface, receives a control instruction of the main control device and controls a plurality of parking space units; therefore, the main control device needs to adopt a multi-serial-port MCU or a conventional MCU plus a UART multi-serial-port expansion chip to obtain a sufficient serial-port communication interface. Compared with the technical scheme of the special control system for the lifting and horizontal moving type stereo garage, the main difference lies in that: the master control device does not participate in the dispatching control of the vehicle board, and each parking space unit corresponds to a secondary device which is connected with the master control device through serial port communication. The technical scheme has the advantages that the functions of the master control device and the secondary device are completely separated, the secondary device is constructed by the parking space unit, resources can be fully utilized, the structure is relatively complex, the overall cost is superior to that of a PLC control system, and application documents lack sufficient introduction or make beneficial prompts for the generalization of the structures of the master controller and the slave controller and the generalization of control flows and operation software of the master controller and the slave controller.
In addition, the patent application which is filed on 3.2.2017, has the application number of 2017100629799 and is named as a control system formed by 1+ N singlechips of parking equipment, wherein the key point of the technical scheme is that 1 describes a comprehensive control device, and N describes N vehicle board control devices for controlling N vehicle carrying boards; obviously, the structure is similar to the second technical solution, and the main difference is that the integrated control device sends the communication data packet containing the code of the vehicle board control single-chip device to all the vehicle board control single-chip devices in a broadcasting mode or a master-slave mode, and the vehicle board control single-chip device sends the communication data packet containing the code of the vehicle board control single-chip device to the integrated control single-chip device. Obviously, the technical scheme still maintains the defect of relatively complex structure, the overall cost still has no advantage compared with a PLC control system, and the application document lacks sufficient introduction or beneficial prompts for the generalization of the structures of the master controller and the slave controller and the generalization of the control flow and the running software of the master controller and the slave controller.
In summary, the technical scheme that the master control chip is a master control structure and a slave control structure of the single chip microcomputer and is applied to the lifting and traversing garage control system is about twenty years from the initial proposal to the present, but the master control chip and the slave control structure are still not applied to actual products so far, and the reason is in the following aspects. Firstly, the functions of the single chip microcomputer are not fully exerted, the hardware architecture is not as reasonable as possible, and the advantages in cost are not achieved; secondly, under the influence of the control flow of the traditional PLC device, a control method which is matched with a hardware architecture and has strong universality cannot be found, so that corresponding control software is designed.
Therefore, how to provide an adopt main control chip to be the owner of singlechip, from control structure, the control flow can fully embody owner, from control structure's advantage, can utilize the resource as far as possible, really reduce cost, can adapt to the commonality that different year sweep configuration modes, hardware and software are strong, be applicable to the lifting and horizontal moving garage control system and the control flow who promotes on a large scale, still the problem that technical staff in the field need to solve urgently.

And each data unit of the initial array list describes two-dimensional coordinates, objective states, initial settings and plate frame codes of a physical parking space of the garage.
First term, two-dimensional coordinates: describing a two-dimensional coordinate of a parking space by at least 8-bit binary digits; wherein, the layer is described by at least 4-bit binary digits, and the column is described by at least 4-bit binary digits; therefore, if the 1 st layer is described with "0001", 15 layers at most can be represented; if the 1 st column is described with "0001", 15 columns can be represented at the maximum.
Second term, objective status: describing the objective state of the parking space by at least 2 binary digits; wherein:
whether the system can be used or not is described by 1-bit binary digits; the term "usable or not" herein means: if the plate frame can be used, the plate frame can be moved into the parking space and can be stopped; if can not use, describe this parking stall space promptly and have the barrier, the sheet frame can not move into this parking stall space, also can not stop in this parking stall space. The garage that the unable parking stall space that exists in the garage usually appears in the inside garage of building, and the leading cause is that roof beam, post, pipeline, the structure of building are located the inside in garage for some parking stall spaces can not set up the sheet frame. It may be agreed that "1" indicates that it can be used and "0" indicates that it cannot be used; of course, other settings may be employed.
1-bit binary digits are used for describing whether the access can be performed or not; the 'entering and exiting' is only suitable for the parking space of the ground floor, and the parking space of other floors cannot enter and exit necessarily; when the parking space is positioned on the ground floor, if the parking space can be accessed, namely the vehicle plate is positioned in the parking space, the vehicle can be driven in or out of the vehicle plate; if the vehicle cannot enter or exit, namely the vehicle plate is located in the parking space, the vehicle cannot enter or exit the vehicle plate. The reason why the parking space is located on the ground floor but cannot enter and exit is that an obstacle exists on one side of the parking space close to the lane. It may be agreed that "1" indicates access, and "0" indicates no access; of course, other settings may be employed.
From the above, the objective states of the parking spaces of two garages with the same number of layers and the same number of rows are different.
Third, initial setting: describing the initial setting condition of a plate frame of a parking space by at least 10 binary digits; wherein: at least 1-bit binary digits are used for describing whether the vehicle board is lifted or not; it may be agreed that "1" indicates yes and "0" indicates no; of course, other settings may be employed; whether the frame or the plate is transversely moved is described by at least 1-bit binary digits; it may be agreed that "1" indicates yes and "0" indicates no; of course, other settings may be employed.
The combined meaning of the above-mentioned continuous 2-bit binary numbers is: "00" indicates no lifting plate, no traversing frame or traversing plate, which describes the initial state of the parking space as an empty parking space; "01" indicates that there is no lifting plate, there is a traversing plate (because it is meaningless to have a traversing frame alone), this situation appears in the parking space of the ground floor, only the traversing plate; "10" indicates that there is a lifting vehicle board and no transverse frame, and this condition appears in the parking space of the highest floor and the lowest floor with the negative floor, and only the lifting vehicle board; "11" indicates a raised deck, a traversing frame (because it is impossible to have both raised and traversing decks in a parking space), which occurs in a parking space in an intermediate layer other than the ground layer, the highest layer, or the lowest layer, and the traversing frame carries the traversing deck.
Except that the plate frame can not be arranged due to the existence of the barrier, each middle layer at least needs to reserve an empty space without the plate frame, and the space becomes a transverse moving vacancy. The above initial setting is to artificially set the specific position of the traverse vacancy.
Describing the slave control device code corresponding to the plate frame by at least 2-bit binary digits; describing plate frame codes corresponding to the plate frames by at least 6-bit binary digits; therefore, if the first slave control device is described by "00", then "11" is the 4 th slave control device; the 1 st panel frame is described as "00001", and the 63 rd panel frame is described as "111111".
The control program of the main control device can obtain the two-dimensional coordinates, the objective state and the related parameters of the initial setting of all the parking space spaces of the garage by reading the initial array list.
Assuming that the total number of layers of the garage is 4, the number of total columns is 4, the number of layers of the ground layer is 2, the 1 st column is the leftmost column, the plate frame number of the 1 st plate frame is the plate frame positioned on the 1 st layer and the 1 st column, the plate frames are arranged in the 1 st layer in an increasing manner from left to right, then the plate frames are arranged in the 1 st column of the 2 nd layer in an increasing manner from left to right, and the rest is analogized; assuming that the data unit length of the initial array list is 24 binary bits (i.e. 3 word lengths), wherein the content of the 1 st word length is a two-dimensional coordinate, the upper 4 bits of the 2 nd word length are in an initial setting condition, the lower 4 bits are unused, and the 3 rd word length is slave control device coding and plate frame coding; the following illustrates how the data units of the initial array list describe the two-dimensional coordinates of the parking space, the initial setting, and the frame coding.
If the content of a certain data unit in the initial array table is "000100101010 XXXX 00000010", that is, the two-dimensional coordinate of the parking space is described as the layer 1, the column 2; can be used; can not enter and exit; the lifting vehicle plate is arranged, and the transverse moving frame is not arranged; the number of the plate frame is No. 2 corresponding to the No. 1 slave control device.
If the content of a certain data unit in the initial array table is "001001001101 XXXX 01000111", the two-dimensional coordinate of the parking space is described as the 4 th column of the layer 2; can be used; accessible (floor 2 is the ground floor); the lifting sweep is not provided, and the transverse sweep is provided; the number of the plate frame is No. 7 corresponding to the No. 2 slave control device.
If the content of a certain data unit in the initial array table is "001100011011 XXXX 00001000", the two-dimensional coordinate of the parking space is described as the 1 st column of layer 3; can be used; not accessible); the lifting vehicle plate is provided with a transverse moving frame; the number of the plate frame is 8 corresponding to the 1 st slave control device.
The static parameter area of the master control device is also provided with a detection parameter table indexed according to the plate frame codes, each data unit of the detection parameter table comprises a plate frame code and a group of corresponding detection parameters, each plate frame code has multiple groups of detection parameters, each group of detection parameters comprises detection information of the plate frame described by at least 16-bit binary digits, wherein:
information whether the plate frame has finished detection or not is described by at least 1-bit binary digits; for example, "0" may be set to indicate that the detection is not completed, and "1" may be set to indicate that the detection is completed; of course, additional settings may be made.
At least 2-bit binary digits are used for describing upward movement in place and upward movement out-of-limit information of the plate frame; for example, "00" may be set to indicate that there is no upward movement detection information and no upward movement overrun detection information, "01" indicates upward movement, "10" indicates upward movement overrun, and "11" indicates upward movement and upward movement overrun; of course, additional settings may be made.
At least 2-bit binary digits are used for describing the downward moving in-place and downward moving overrun information of the plate frame; for example, "00" indicates no move down, "01" indicates move down to the right, "10" indicates move down over limit, "11" indicates move down to the right and move down over limit; of course, additional settings may be made.
Left shift to bit and left shift overrun information of the plate frame described by at least 2-bit binary digits; for example, "00" may be set to indicate no left move, "01" to indicate left move to position, "10" to indicate left move overrun, and "11" to indicate left move to position and left move overrun; of course, additional settings may be made.
Right shift to bit and right shift overrun information of the plate frame described by at least 2-bit binary digits; for example, "00" may be set to indicate no right movement, "01" to indicate right movement to the right, "10" to indicate right movement overrun, and "11" to indicate right movement to the right and right movement overrun; of course, additional settings may be made.
At least 2 bits of binary digits describe the opening and resetting information of the falling protector of the plate frame; for example, "00" can be set to indicate that the safety catcher is not arranged, "01" indicates that the safety catcher is reset to be normal, "10" indicates that the safety catcher is opened to be normal, and "11" indicates that the safety catcher is out of order; of course, additional settings may be made.
At least 1 bit binary digit to describe the chain cable state information of the plate frame; for example, a "0" may be set to indicate that the state is normal or no strand detection, and a "1" may indicate that the state is not normal (e.g., broken); of course, additional settings may be made.
At least 4 bits of binary digits to describe the resulting state information of the plate frame; if the result state is normal with the highest bit being "0", up to 8 normal result states can be represented from "0000" to "0111".
For a panel frame with only a lift panel, there is one of three normal result states:
the state number 1 is in an initially set parking space and is in a determined state of standing in the parking space;
the state number 2 is a determined state of standing of a ground layer which is in an initially set parking space and is positioned vertically below or vertically above;
the state number 3 is in the initially set parking space, but the specific position cannot be specified, and is in the intermediate state of ascending or descending.
The three normal result states correspond to three groups of detection information, and the corresponding plate frame number, detection information and state number are respectively used as a group of data information to be written into three data units of the detection parameter table.
When only the plate frame of the lifting vehicle plate is in the state number 3, the control program of the master control device needs to send an ascending or descending operation instruction of the corresponding plate frame to the corresponding slave control device according to the slave control device code and the plate frame code corresponding to the plate frame, so that the corresponding lifting vehicle plate returns to the state number 1.
If the detection result of the plate frame of the lifting plate does not accord with one of the three states, the detection result indicates that the position of the plate frame is in an abnormal state or a detection device for detecting the plate frame is in a fault state.
For a panel frame that only traverses the panel, there is one of three normal result states:
the state number 1 is in a determined state of the initially set parking space;
a state number 2, which is a determined state on the left side or the right side of the initially set parking space;
the state number 3, the specific position of which cannot be determined, is in an intermediate state in which the initially set parking space moves to the left or to the right.
The three states correspond to three groups of detection information, and the corresponding plate frame number, detection information and state number are respectively used as a group of data information to be written into three data units of the detection parameter table.
When only the plate frame of the traverse car plate is in the state number 3, the control program of the master control device needs to send a left-shift or right-shift operation instruction of the corresponding plate frame to the corresponding slave control device according to the slave control device code and the plate frame code corresponding to the plate frame, so that the corresponding traverse car plate returns to the state number 1 or the state number 2.
If the detection result of the plate frame of the transverse moving plate does not meet one of the three states, the detection result indicates that the position of the plate frame is in an abnormal state or a detection device for detecting the plate frame is in a fault state.
For sheet frames with cross-sliding frames and lift car decks, there are one of seven normal result states:
the state number is 1, the transverse moving frame is in an initially set parking space, and the lifting vehicle plate is in a determined state of standing in the parking space;
the state number is 2, the transverse moving frame is in an initially set parking space, and the lifting vehicle plate is in a determined state of standing on a ground layer vertically below or vertically above;
the state number 3 is that the transverse moving frame is in the initially set parking space, and the lifting plate body position cannot be determined and is in the middle state of lifting or descending;
the state number is 4, the transverse moving frame is positioned on the left side or the right side of the initially set parking space, and the lifting vehicle plate is positioned in a determined state of standing in the parking space;
the state number is 5, the transverse moving frame is positioned on the left side or the right side of the initially set parking space, and the lifting vehicle plate is positioned in a determined state of standing on a ground layer positioned vertically below or vertically above;
the state number 6 is that the traverse frame is positioned at the left side or the right side of the initially set parking space, and the lifting plate body position cannot be determined and is in a middle state of ascending or descending;
and the state number is 7, the lifting vehicle plate is positioned in the transverse moving frame and stands still, and the specific position of the transverse moving frame cannot be determined.
The seven states correspond to seven groups of detection information, and the corresponding plate frame number, detection information and state number are respectively used as a group of data information to be written into seven data units of the detection parameter table.
When a transverse moving frame exists and the plate frame with the lifting vehicle plate is in the state number 3, a control program of the master control device needs to send a rising or falling operation instruction of the corresponding plate frame to the corresponding slave control device according to the slave control device code and the plate frame code corresponding to the plate frame, so that the corresponding lifting vehicle plate returns to the state number 1;
when a transverse moving frame exists and the plate frame with the lifting vehicle plate is in the state number 6, a control program of the master control device needs to send a lifting or descending operation instruction of the corresponding plate frame to the corresponding slave control device according to the slave control device code and the plate frame code corresponding to the plate frame, so that the corresponding lifting vehicle plate returns to the state number 4;
when the plate frame with the transverse moving frame and the lifting plate is in the state number 7, the control program of the master control device needs to send a left-moving or right-moving operation instruction of the corresponding plate frame to the corresponding slave control device according to the slave control device code and the plate frame code corresponding to the plate frame, so that the corresponding plate frame returns to the state number 1 or the state number 4.
If the detection result of the plate frame with the transverse moving frame and the lifting plate does not accord with one of the seven states, the detection result indicates that the position of the plate frame is in an abnormal state or a detection device for detecting the plate frame is in a fault state.
