[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0033] At present, there are often more than ten docking points in the coal sampling and sample preparation system, which means that more than ten rolling shutter doors need to be set up, and their keys correspond to the rolling shutter doors one by one. Figure 1 The figure is a schematic diagram of the correspondence between rolling doors and keys in a coal sampling and sample preparation system in the prior art. In this storage system where rolling doors and remote control keys are one-to-one, the keys of each rolling door are similar in appearance and difficult to distinguish. The keys and rolling doors can only be numbered accordingly to facilitate manual management. The driver of the cargo transfer vehicle needs to carry a large number of keys during work, and must carefully check and distinguish the keys at each docking point. Only when the correct key is found can the sample barrel be transferred normally. This process often requires multiple attempts and errors until the correct rolling door remote control key is found. Because there are many docking points in the coal sampling and sample preparation system, and there are also many keys for electric rolling doors, it is difficult for the cargo transfer vehicle driver who transfers the sample barrel to manage the keys and find and confirm the keys.

[0034] In order to solve the aforementioned problem, an embodiment of the present invention provides a multi-roller door control device, which is applied to a coal sampling and sample preparation system. Figure 2 A schematic diagram of a multi-roller door control device provided by an embodiment of the present invention, referring to Figure 2 The multi-roller door control device 200 includes a wireless control module 201 and a plurality of wireless receiving modules 202. All wireless receiving modules 202 are divided into a plurality of groups. Figure 2 X groups are shown, and X can be any positive integer greater than 1. The wireless control module 201 is arranged on the cargo transfer vehicle, and the wireless control module 201 includes an operating unit 203 and a transmitting unit 204; the operating unit 203 corresponds to each group of the wireless receiving module 202, and the operating unit 203 is used to adjust its own state according to the driver's operation; the transmitting unit 204 is connected to the operating unit 203, and is used to send a corresponding wireless control signal according to the state of the operating unit 203. The wireless receiving module 202 is arranged at the corresponding rolling door, connected to the driving device of the rolling door, and is used to receive the corresponding wireless control signal and control the switch state of the rolling door according to the wireless control signal, wherein the relative distance between the wireless receiving modules 202 in the same group is greater than twice the control distance of the wireless control module 201.

[0035] Specifically, the wireless control module 201 refers to a rolling door remote control or remote control component provided on the cargo transfer vehicle, which can send out wireless control signals for controlling each group of wireless receiving modules 202 according to the operation of the driver. The control distance of the wireless control module 201 refers to the maximum value of the effective transmission distance of the wireless control signal sent by the wireless control module 201. For example, the wireless control signal is an infrared signal, and the maximum value of the effective transmission distance of the infrared signal is 10 meters, then the control distance of the wireless control module 201 is 10 meters. The operating unit 203 refers to the operating component in the wireless control module 201, which corresponds to each group of the wireless receiving module 202 one by one. For example, the operating unit 203 can include a switch button, a switch knob or a gear switch. In the case where the rolling door to be controlled belongs to the first group, the control of the target rolling door can be achieved by operating the operating unit 203 corresponding to the first group. The transmitting unit 204 refers to the wireless signal transmitting component in the wireless control module 201, which can generate corresponding wireless control signals according to the status of each operating unit 203 to control the wireless receiving module 202 in the corresponding group of the operating unit 203. Exemplarily, the transmitting unit 204 can generate a wireless control signal corresponding to the first group of wireless receiving modules 202 when the operating unit 203 corresponding to the first group is changed from an open state to a closed state, so as to control the rolling shutter door where the first group of wireless receiving modules 202 are located within the control distance to implement a closing action.

[0036] The wireless receiving module 202 refers to a control component arranged at the rolling door, and corresponds to the type of the transmitting unit 204 in the wireless control module 201. Exemplarily, if the transmitting unit 204 includes an infrared transmitting device, the wireless receiving module 202 includes an infrared receiving device. When the distance between the transmitting unit 204 and the wireless receiving module 202 is less than the control distance, the wireless receiving module 202 and the transmitting unit 204 can achieve wireless communication connection. The wireless receiving modules 202 in the same group correspond to the same operating unit 203. When the transmitting unit 204 sends a wireless control signal according to the state of the operating unit 203, if the wireless receiving module 202 in the corresponding group of the operating unit 203 is within the control range, the wireless control signal can be received and the opening and closing state of the corresponding rolling door can be controlled according to the wireless control signal, wherein the control range is a circular range with the transmitting hole of the transmitting unit 204 as the center and the control distance as the radius. Exemplarily, the wireless receiving module 202 may include a signal receiving unit and a control unit, and the signal receiving unit corresponds to the type of the transmitting unit and can receive the wireless control signal sent by the transmitting unit. The control unit can generate a control signal according to the wireless control signal, and the driving device of the rolling door can adjust the opening and closing state of the rolling door according to the control signal.

[0037] For example, Figure 3A schematic diagram of the distribution of multiple rolling shutter doors in a coal sampling and sample preparation system provided by an embodiment of the present invention, combined with Figure 2 and Figure 3 Since the relative distance between the wireless receiving modules 202 in the same group needs to be greater than twice the control distance of the wireless control module 201, and the wireless receiving modules 202 are set at the corresponding rolling shutter doors, it can be determined that two rolling shutter doors with a relative distance less than twice the control distance are not set in the same group, and their corresponding wireless receiving modules 202 are not set in the same group. According to this setting principle, if Figure 3 In the coal sampling and sample preparation system, the control distance of the wireless control module 201 is equal to 10 meters, so the grouping of the rolling shutter doors and the wireless receiving modules 202 can be set to the same group of rolling shutter doors No. 1, No. 3, No. 4 and No. 5 and their corresponding wireless receiving modules 202, which can be recorded as Group A, while the rolling shutter doors No. 2 and No. 6 and their wireless receiving modules 202 are another group, which can be recorded as Group B. Corresponding to the two groups of wireless receiving modules 202, there are also two operating units 203 in the wireless control module on the cargo transfer vehicle, one for controlling the wireless receiving module 202 of Group A, and the other for controlling the wireless receiving module 202 of Group B. When the driver drives the cargo transfer vehicle to the vicinity of rolling shutter door No. 1, he can operate the operating unit corresponding to Group A to send a control signal. Because the distance between the wireless receiving module 202 at the No. 1 rolling door and the wireless control module 201 is within the control distance, and the distance between the wireless receiving module 202 at other rolling doors in group A and the No. 1 rolling door exceeds the control distance of the wireless control module 201, the wireless control signal is only effective for the No. 1 rolling door, and the other rolling doors in group A do not act. Although the distance between the wireless receiving module 202 at the No. 2 rolling door in group B and the wireless control module 201 is also within the control distance, the wireless control signal sent by the wireless receiving module 201 for controlling group A is invalid for the wireless receiving module 202 in group B, so the No. 1 rolling door can be controlled separately without affecting the status of other rolling doors.

[0038] The multi-roller door control device provided in this embodiment is provided with a wireless control module and multiple groups of wireless receiving modules. The wireless control module is arranged on the cargo transfer vehicle, and the wireless control module includes an operating unit and a transmitting unit; the operating unit corresponds to each group of wireless receiving modules one by one, and the operating unit is used to adjust its own state according to the operation of the driver; the transmitting unit is connected to the operating unit, and is used to send a wireless control signal corresponding to the operating unit according to the state of the operating unit. The wireless receiving module is arranged at the corresponding roller shutter door, connected to the driving device of the roller shutter door, and is used to receive the corresponding wireless control signal, and control the switch state of the roller shutter door according to the wireless control signal, wherein the relative distance between the wireless receiving modules in the same group is greater than twice the control distance of the wireless control module, so that the individual control of multiple roller shutter doors is realized. On the one hand, the wireless control module is arranged on the cargo transfer vehicle, and the separation of people and keys avoids the loss and duplication of keys, thereby improving the safety of the system. On the other hand, by setting the relative distance between the wireless receiving modules in the same group to be greater than twice the control distance, the control of the entire group of wireless receiving modules by a single operating unit is realized, the number of operating units in the wireless control module is reduced, and the difficulty of operation of the driver is greatly reduced.

[0039] Optionally, Figure 4 A schematic diagram of another multi-roller door control device provided by an embodiment of the present invention, based on the above embodiment, Figure 4 , the number of other wireless receiving modules 202 whose relative distance to any wireless receiving module 202 is less than or equal to twice the control distance is less than or equal to N. The number of groups of wireless receiving modules 202 is equal to N+1, where N is a positive integer. Figure 4 FIG. 4 shows an exemplary multi-roller door control device in the case where N=1.

[0040] Specifically, the number of other wireless control modules 202 within the control range of any wireless receiving module 202 in the multi-roller door control device 200 is less than or equal to N, wherein the control range of the wireless receiving module 202 refers to a range where the distance between the wireless receiving module 202 and the wireless receiving module 202 is less than or equal to the control distance. Two wireless receiving modules 202 whose distance is less than or equal to the control distance are divided into different groups, and the number of groups of wireless receiving modules 202 can be equal to N+1. Correspondingly, the number of operating units 203 in the wireless control module 201 is also set to N+1. This setting minimizes the number of groups and makes the structure of the wireless control module 201 the simplest, further reducing the difficulty of operation for the driver and improving the convenience of the control device.

[0041] Optionally, Figure 5 A schematic diagram of the outer surface of a wireless control module provided by an embodiment of the present invention, Figure 6 A perspective schematic diagram of a wireless control module provided by an embodiment of the present invention, Figure 6The perspective direction is Figure 5 The arrows indicate that, based on the above embodiments, Figure 5 and Figure 6 The wireless control module 201 further includes a packaging shell 501; the operating unit includes a switch button or a switch knob 502 ( Figure 5 and Figure 6 Only the case where the operating unit includes a switch knob is shown in the figure), the switch button or switch knob 502 is arranged on the surface of the package shell 401; the transmitting unit includes a remote control card 503 and a transmitter 504; the remote control card 503 is arranged in the package shell 501, connected to the operating unit, and used to generate an original control signal according to the state of the switch button or switch knob 502; the transmitter 504 is arranged on the surface of the package shell 501, connected to the remote control card 503, and used to convert the original control signal into a wireless control signal and send the wireless control signal. The wireless control module 201 also includes a power supply unit 505, which is respectively connected to the operating unit and the transmitting unit (the connection relationship of the power supply units is not shown) to supply power to the operating unit and the transmitting unit.

[0042] Specifically, the packaging shell 501 refers to the outer packaging shell of the wireless control module. For example, the packaging shell can be a hard resin. The different gears of the switch button or the switch knob 502 can correspond to the opening and closing of the rolling door respectively. For example, when the driver rotates the switch knob 502 of the group A operating unit to the rolling door opening gear, the group A wireless receiving module whose distance from the wireless control module is less than or equal to the control distance will control the corresponding rolling door to open according to the control signal. The remote control board 503 refers to a wireless control signal generating circuit, which can generate a corresponding wireless control signal according to the state of the operating unit (that is, the gear position of the switch button or the switch knob in this embodiment). The control signals generated according to different operating units are different, so that the corresponding control signal of this group can only be received and recognized by the wireless receiving module in this group. The transmitter 504 refers to a transmitting device of the wireless control signal. For example, the transmitting unit includes at least one of various transmitters such as a Bluetooth circuit, an infrared circuit and an ultrasonic circuit; correspondingly, the wireless receiving module includes at least one of a Bluetooth receiving circuit, an infrared receiving circuit and an ultrasonic receiving circuit.

[0043] The power supply unit 505 refers to the power supply component of the wireless control module, which can supply power to the operating unit and the transmitting unit. Exemplarily, the power supply unit 505 can include a storage battery pack. The power supply unit 505 can include an independent power supply component or a power supply component that shares a storage battery with the cargo transfer vehicle.

[0044] For example, Figure 7 A schematic diagram of another multi-roller door control device provided by an embodiment of the present invention, referring to Figure 7 , the number of remote control boards 503 and transmitters 504 is equal to the number of operating units, and they correspond to the operating units one by one. When the driver changes the state of any operating unit, the remote control board 503 corresponding to the operating unit will generate a corresponding wireless control signal, and the transmitter 504 corresponding to the operating unit will transmit the wireless control signal to achieve the control of the corresponding group of rolling doors. In this example, each group of wireless receiving modules 202 corresponds to a remote control board 503 and a transmitter 504, and the wireless control module 201 can be regarded as a collection and encapsulation of multiple groups of rolling door remote controllers. Each remote control board 503 and transmitter 504 only needs to send a control signal that can be received by the corresponding group of wireless receiving modules 202. Figure 8 A schematic diagram of a structure of another multi-roller door control device provided by an embodiment of the present invention, referring to Figure 8 , the number of remote control boards 503 and transmitters 504 are both 1. When the driver operates any state of the operating unit, the unique remote control board 503 will generate a wireless control signal corresponding to the operating unit according to the state change of the operating unit, and the unique transmitter 504 will send out the wireless control signal to achieve the control of the corresponding group of rolling doors. In this example, multiple groups of wireless receiving modules 202 all correspond to the same remote control board 503 and the same transmitter 504, and the remote control board 503 and the transmitter 504 need to send out different wireless control signals corresponding to each group of wireless receiving modules 202.

[0045] Optionally, Fig. 9 A schematic diagram of a rolling door and its surrounding facilities provided by an embodiment of the present invention, referring to Fig. 9 The multi-roller door control device further includes: an identification symbol 901 corresponding to the wireless receiving module. The identification symbol 901 is set at the corresponding roller door, and the identification symbol 901 includes group data and number data.

[0046] Specifically, the identification symbol 901 refers to a symbol set near the rolling door for showing identification information such as the group data of the rolling door. Exemplarily, the identification symbol can be set on the wall near the rolling door in a screen printing manner. The identification symbol 901 may include group data and number data. The group data may indicate the grouping information of the rolling door and its wireless receiving module, which is convenient for the driver to associate the rolling door with the operating unit of the corresponding group, avoiding the driver's search and trial and error. The number data may indicate the unique number of the rolling door and its wireless receiving module in the group, which is convenient for the driver to distinguish different rolling doors in the group. Exemplarily, the identification symbol set at the third rolling door of group A may be A3.

[0047] The multi-rolling door control device provided in the present embodiment is further provided with an identification symbol at each rolling door. The identification symbol corresponds one-to-one with the wireless receiving module and can indicate the group data and number data of the wireless receiving module. When a certain rolling door needs to be controlled, the driver can operate the corresponding operating unit according to the identification symbol at the rolling door, thereby avoiding the driver's searching and trial and error and improving the control efficiency of the control device.

[0048] The embodiment of the present invention further provides a storage system.

The wireless control module of the multi-rolling shutter door control device is provided on the cargo transfer vehicle, and can send out corresponding control signals according to the operation of the driver. The wireless receiving module of the multi-rolling shutter door control device is provided at each rolling shutter door, and can control the opening and closing state of the rolling shutter door according to the corresponding control signal, thereby realizing the state control of the rolling shutter doors of the warehousing system. Through the group setting, all the rolling shutter doors are controlled by using the minimum number of operating units, which greatly reduces the complexity of the multi-rolling shutter door control device. The wireless control module is integrated on the cargo transfer vehicle, which avoids the loss and duplication of keys and improves the security of the warehousing system.

[0050] Optionally, based on the aforementioned embodiment, the cargo transfer vehicle and the wireless control module thereon share a power supply unit, which can not only provide electrical energy for the cargo transfer vehicle and support at least one of the power, lighting or ignition functions of the cargo transfer vehicle, but also power the wireless control module to realize remote control of the rolling door, further reducing the complexity of the multi-rolling door control device.

[0051] The multi-roller door control device and storage system provided by the embodiment of the present invention are provided with a wireless control module and multiple groups of wireless receiving modules. The wireless control module is arranged on the cargo transfer vehicle, and the wireless control module includes an operating unit and a transmitting unit; the operating unit corresponds to each group of wireless receiving modules one by one, and the operating unit is used to adjust its own state according to the operation of the driver; the transmitting unit is connected to the operating unit, and is used to send a wireless control signal corresponding to the operating unit according to the state of the operating unit.
