Description

Technical Field

[0001] The present invention relates to the technical field of hardware management, and more specifically, to an elevator management device and an elevator management method thereof. Background Art

[0002] During the development and production phase of new products, confidentiality is particularly important. Therefore, the transportation of related goods during the development and production phase of new products requires the use of specific logistics elevators to ensure that everything is under control. In the existing process, it is generally emphasized that the employee who picks up and puts the goods must be the same person. Suppose an employee places the goods from the first-floor workshop to the logistics elevator, then enters the second-floor or higher-floor workshop through the security check channel, and goes to the corresponding logistics elevator to pick up the goods. If the employee forgets to select the elevator floor when placing the goods, then the employee cannot get the goods at the corresponding logistics elevator because the logistics elevator cannot go up. It is necessary to exit the workshop through the security check channel, open the logistics elevator to reselect the floor, and then enter the workshop through the security check channel again. This round trip is time-consuming, labor-intensive, and inefficient.

[0003] Therefore, how to provide an elevator management device to promptly remind employees to select the destination floor after placing the goods in the logistics elevator and improve the transfer efficiency has become a technical problem that urgently needs to be solved. Summary of the invention

[0004] In view of the above problems, the object of the present invention is to provide an elevator management device and an elevator management method, so as to timely remind the cargo pick-up and delivery staff to select the destination floor after placing the cargo.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is apparent that these embodiments may also be implemented without these specific details. In other examples, for ease of describing one or more embodiments, known structures and devices are shown in the form of block diagrams.

[0031] In view of the confidentiality requirements of units or workshops with strong confidentiality, when the freight elevator in the environment transports goods on different floors, in order to prevent transportation errors, resulting in loss of goods or receipt of goods on other floors leading to leakage, it is required that no people be on the freight elevator during transportation. In order to solve the problem of low transportation efficiency caused by the employees who pick up and put goods forgetting to select the elevator floor when placing goods in the prior art, the present invention proposes an elevator management device and elevator management method that can timely remind the employees who pick up and put goods to select the destination floor after placing the goods.

[0032] In order to describe the elevator management device and the elevator management method thereof in detail, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 The logical structure of the elevator management device according to the embodiment of the present invention is shown. Figure 2 A diagram showing an example of the configuration of an infrared detection unit according to an embodiment of the present invention is shown.

[0034] like Figure 1 and Figure 2 As shown together, the elevator management device provided in this embodiment mainly includes an infrared detection unit 101, a microprocessor 102 and a reminder unit 103.

[0035] Among them, the infrared detection unit 101 is mainly used to determine whether the employee is in the elevator car;

[0036] The microprocessor 102 is used to determine the shielding condition of the infrared detection unit and the floor button condition in the elevator after the elevator door is opened by swiping a card, and control the opening and closing of the elevator according to the shielding condition and the button condition, and send reminder control information to the reminder unit 103; wherein, if at least one group of infrared detection units is blocked, the elevator will remain normally open; if all infrared detection units are not blocked, it is determined whether the employee has left the elevator car, and corresponding reminder control information is sent according to the judgment result; wherein, if the employee has not left the elevator car, the elevator continues to be normally open, and a reminder message is sent to select the desired floor and leave the elevator in time; if the employee has left the elevator car, it is further detected whether there is a floor button pressed at present, if not, the elevator continues to be normally open, and a prompt message to select the desired floor is sent; correspondingly, if it is detected that a floor button has been pressed, the elevator is closed and the elevator is run to the target floor corresponding to the floor button.

[0037] The reminder unit 103 is used to send reminder information according to the reminder control information of the microprocessor 102. In a specific embodiment of the present invention,

[0038] In the description of the following embodiments of the present invention, the reminder unit can be a device with a sound function, such as a speaker, which is used to remind employees through similar voice prompt information such as "Please press the floor button", "Please select a floor before leaving the elevator", "Please select the arrival floor", etc., or it can be a buzzer, which is used to remind employees to select a floor through a specific buzzer prompt sound; or, in order to give visual reminders to employees who pick up and put away goods at the same time, it can also include a sound function device and a light-emitting function device to remind employees through a combination of flashing light, voice, buzzer sound, etc.

[0039] The microprocessor in the present invention can be composed of a microprocessor such as a single chip microcomputer, and the infrared detection unit includes an infrared transmitting unit and an infrared receiving unit arranged in pairs. Figure 2 In the embodiment shown, at least two groups of infrared detection units are arranged in the horizontal direction on the boxes on both sides of the elevator door frame, and each group of infrared detection units has a transmitting unit and a receiving unit, which are used to determine whether a person is in the elevator. In addition, transmitting / receiving units can be added in the horizontal / vertical direction according to actual needs to increase the detection accuracy. Another group of infrared detection units can also be arranged on the box on the upper side of the elevator door frame to further increase the detection accuracy.

[0040] In another specific embodiment of the present invention, the elevator management device further includes a timing unit (not shown in the figure), which is used to start timing when the microprocessor 102 receives a signal that the last infrared detection unit 101 changes from a blocked state to an unblocked state. If no employee is detected pressing a floor button in the preset room, the microprocessor 102 sends a prompt message of selecting the desired floor to the reminder unit 103 while keeping the elevator in a normally open state. If an employee is detected pressing a floor button in the preset room, the microprocessor 102 clears the timing unit, closes the elevator, and controls the elevator to run to the target floor corresponding to the floor button.

[0041] The elevator management device of the present invention will be further described below by taking an example having three groups of infrared detection units.

[0042] Figure 3 FIG. 1 shows a schematic diagram of three groups of infrared detection units detecting employees entering and leaving an elevator according to an embodiment of the present invention. Figure 3 As shown, the working process of the elevator management device in this embodiment is as follows:

[0043] First, the employee swipes the authorized employee card to open the elevator door. When the employee enters the elevator to place the goods, the infrared detection unit is blocked. At this time, as long as at least one group is blocked, the elevator will remain open and will not close automatically.

[0044] When the infrared detection unit is not blocked, Figure 3 Taking the three groups of infrared detection units shown in the figure as an example, the following situations can be considered:

[0045] like Figure 3 As shown in (a), if the last signal received by the microprocessor that changes from the blocked state to the unblocked state comes from the third group of infrared detection units, then it is determined that the current employee is inside the elevator car, and the microprocessor controls the elevator door to be in the normally open state. If the employee is not detected pressing the floor button within the specified time, the microprocessor 102 will control the reminder unit 103 to make a sound while maintaining the elevator door normally open, reminding the employee to select the required floor and leave the elevator in time, and not to ride with the goods at the same time.

[0046] like Figure 3 As shown in (b), if the last signal received by the microprocessor that the state changes from blocked to unblocked comes from the third infrared detection unit, then it is determined that the current employee has left the elevator, and the microprocessor detects whether a floor button is currently pressed. If not, the elevator continues to be open and controls the reminder unit to send a prompt message for selecting a floor. Correspondingly, if it is detected that a floor button has been pressed, the elevator door is controlled to close, and then the elevator runs to the target floor corresponding to the floor button.

[0047] Figure 4 The flowchart of the elevator management method according to the embodiment of the present invention is shown.

[0048] like Figure 4 As shown, the elevator management method provided in this embodiment uses the elevator management device as described above to implement elevator management; it includes:

[0049] S401: Open the elevator door by swiping an authorized employee card;

[0050] S402: Determine the shielding status of the infrared detection unit through the microprocessor; if at least one group of infrared detection units is blocked, the elevator will remain normally open; if all infrared detection units are not blocked, determine whether the employee has left the elevator car, and issue corresponding reminder control information based on the determination result; if the employee has not left the elevator car, keep the elevator normally open, and issue a reminder to select the desired floor and leave the elevator in time; if the employee has left the elevator car, further detect whether there is a floor button currently pressed, if not, keep the elevator normally open, and issue a reminder to select the desired floor; S403: Issue a reminder message through the reminder unit according to the reminder control information.

[0051] Correspondingly, if the microprocessor detects that a floor button has been pressed, the elevator is shut down and the elevator is run to the target floor corresponding to the floor button.

[0052] In addition, in order to provide the cargo pick-up and delivery employees with appropriate time to carry out cargo pick-up and delivery, sorting and other processing in the elevator car, an optional technical solution is to use a timing unit to count when the microprocessor receives a signal that the last infrared detection unit changes from an obstructed state to an unobstructed state; wherein, if no employee is detected pressing a floor button in the preset room, the microprocessor 102 will send a prompt message to select the required floor while keeping the elevator in a normally open state.

[0053] More specific implementations of the above-mentioned elevator management method can refer to the above-mentioned description of the embodiment of the elevator management device, which will not be described in detail here.

[0054] The elevator management device and the elevator management method shown in the above embodiments use an infrared detection unit to detect whether the employees who pick up and place goods are in the elevator car and whether they press the floor button, thereby promptly reminding the employees to press the floor button, effectively preventing the employees from forgetting to select the elevator floor when placing goods, thereby correspondingly improving the efficiency of cargo transfer.
