Description

Technical Field

[0001] The present invention relates to the field of borrowing and returning equipment, and in particular to a borrowing and returning management system and a borrowing and returning method for self-service equipment. Background Art

[0002] In enterprises or research institutions, there are many instruments and equipment provided as public resources to employees or technicians. These instruments and equipment are expensive and of various types. They may belong to various departments or laboratories. If no one manages the instruments and equipment, the equipment may be idle for a period of time without knowing where it is. Others who want to borrow them do not know where the instruments and equipment are, which will inevitably lead to a waste of public resources. If the equipment is managed by a dedicated person, when the number of instruments and equipment is large, the labor cost investment is high and the management efficiency is low.

[0003] The current instrument borrowing and returning management system usually adopts two methods. One is cabinet management, that is, the equipment is uniformly stored in the partitions of the cabinet, and the borrower borrows it from the cabinet. However, this method is suitable for places that can be centrally managed and cannot be managed in a distributed manner. The other is mobile phone scanning, which uses mobile phone software to scan the identification code on the device to borrow the device. However, this method requires the maintenance of the background server, which has a high maintenance cost. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a self-service equipment borrowing and returning management system with low power consumption and capable of returning the equipment to a designated location after borrowing. To achieve the above objectives, the present invention adopts the following specific technical solutions:

[0005] A self-service instrument and equipment borrowing and returning management system, comprising a key, a lock terminal unit, a housing and a network information management unit;

[0006] The key is fixedly connected to the instrument and equipment with a gap through a flexible member, and the instrument and equipment is provided with a unique key;

[0007] The lock terminal unit is arranged on the housing, and the lock terminal unit comprises a pin lock cylinder matched with the key;

[0008] The network information management unit is connected to the lock terminal unit for communication, and is used for receiving and managing the borrowing and returning information sent by the lock terminal unit.

[0009] The present invention can achieve the following technical effects:

[0010] The present invention provides a self-service instrument and equipment borrowing and returning management system, which can be connected to the instrument and equipment without affecting the normal use of the instrument and equipment, and adopts a special key design to ensure that the equipment can be returned to the designated location after being borrowed. The system can realize distributed management, and one management terminal can manage one or more instruments and equipment. The display screen display device can display the instrument name, borrower name, borrowing time, and whether it has been returned, which is convenient for other borrowers or managers to find instruments and equipment.

[0011] The shell of the integrated lock terminal unit is small and easy to fix to any position. The instrument and the shell are connected by flexible parts such as easy-pull, so there can be a certain distance. The key adopts a dedicated key design to ensure that the instrument can be returned to the surrounding of the shell when the equipment is returned, which can form a self-disciplined instrument and equipment management. The display screen adopts an e-paper display screen, which only consumes power when displaying information, so the power consumption is extremely low. Wireless networking is used for communication connection, and the network push information is turned on only when there is a change in borrowing and returning, which effectively reduces the power consumption of the network and has extremely low maintenance costs. The shell has built-in charging and power detection functions, and the battery uses a universal rechargeable battery for easy replacement.

[0012] The borrowing and returning method provided by the present invention can realize self-service borrowing and returning of instruments and equipment, and the instruments and equipment are connected to the housing at a certain distance through flexible parts, so as to prevent the loss of the instruments and equipment and visualize the instruments and equipment.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0022] The purpose of the present invention is to provide a self-service equipment borrowing and returning management system with low power consumption and capable of returning the equipment to a designated location after borrowing. The self-service equipment borrowing and returning management system provided by the present invention will be described in detail below through specific embodiments.

[0023] Figure 1 The main structure of the borrowing and returning management system of the present invention is shown as follows: Figure 1 As shown, it includes a key 1, a lock body terminal unit, a housing 3 and a networking information management unit.

[0024] The key 1 is fixedly connected to the instrument at a certain distance through a flexible member, and the instrument is provided with a unique key 1; the lock terminal unit is provided on the housing 3, and the lock terminal unit includes a pin lock cylinder 231 that cooperates with the key 1. The network information management unit is connected to the lock terminal unit for communication, and the network information management unit is used to receive and manage the borrowing and returning information sent by the lock terminal unit.

[0025] The corresponding method of use is that when borrowing the instrument, the key 1 leaves the pin lock cylinder 231; when returning the instrument, the key 1 is fixedly connected by the pin lock cylinder 231, and the connection distance between the instrument and the housing 3 is controlled by the flexible member.

[0026] The borrowing and returning management system and the borrowing and returning method realize the distance control between the instrument and the housing 3, avoid the loss of the instrument, and visualize the location and return status of the instrument.

[0027] In a preferred embodiment of the present invention, the lock terminal unit includes a radio frequency identification card reader module 21, a display screen 22, a power supply module, a pin lock cylinder module 23 and a main control module.

[0028] Among them Figure 3The key is fixedly connected to the instrument through a flexible part, and the instrument is provided with a unique key. Preferably, the flexible part is a drawbar, which has a certain length, and can realize controllable distance between the instrument and the shell 3 when the key 1 is connected to the shell 3, and the instrument is not easy to lose; at the same time, it has a certain elasticity, and can retract the key 1 in time when the key 1 is separated from the shell 3, so as to facilitate the safekeeping of the key 1. The shell of the drawbar is fixed to the surface of the instrument with double-sided tape, or the instrument that is not convenient to stick can be attached to the instrument through a rope system, and the other end of the drawbar stretch rope is connected to the key 1.

[0029] Among them Figure 2 As shown, the lock terminal unit is arranged on the housing 3, and the lock terminal unit includes a radio frequency identification card reader module 21, a display screen 22, a power supply module, a pin lock core module 23 and a main control module.

[0030] The RFID card reader module (radio frequency identification card reader module) 21 is used to read the identity information of the borrower's identity card. This module is a prior art and will not be described in detail here.

[0031] It is preferred to use a low-energy-consuming e-paper screen (electronic ink screen) to display the device name, the lender's loan time, and whether it has been returned.

[0032] The power supply module can be charged through the USB interface, or the rechargeable battery can be directly replaced. The power supply module can check the power of the rechargeable battery and remind the borrower or manager to charge when the power is low. The borrowing and returning method of this system includes the borrowing process and the returning process:

[0033] like Figure 4-6 As shown, the steps of the borrowing process include: when the borrower borrows the instrument or equipment, after the borrower swipes the card successfully, he presses the serial number button 25 of the corresponding borrowing equipment (a one-to-one lock body does not require a selection button), and the borrower turns the key 1 to make it leave the pin lock cylinder 231;

[0034] The steps of the returning process include: when the borrower returns the instrument, the borrower locks the key 3 on the pin lock cylinder 231 and controls the connection distance between the instrument and the housing 3 through the flexible member.

[0035] The pin lock cylinder module 23 includes a pin lock cylinder 231, a lock tongue 232, a spring 233, a push-pull electromagnet 234 and a micro switch 235. The main control module is used to identify identity information and is connected to the push-pull electromagnet 234 and the micro switch 235. The connection between the three belongs to the existing technology of electrical components and will not be repeated here.

[0036] The pin lock cylinder 231 has a locked position and an unlocked position, and the two positions can be switched by rotating relative to the housing 3; the lock tongue 232 is fixedly connected to the pin lock cylinder 231, and the lock tongue 232 is connected to the housing 3 through a spring 233, and a tongue notch 2321 is provided on the lock tongue 232. When the instrument is not borrowed, the pin lock cylinder 231 is in the locked position, and the key 1 of the instrument is inserted into the pin lock cylinder 231 and cannot be pulled out, and the lock tongue 232 contacts the micro switch 235, and the micro switch 235 controls the push-pull electromagnet 234 to cut off the power, so that it can be stuck in the tongue notch 2321, and the position of the lock tongue 232 is kept unchanged.

[0037] When the borrower uses an IC card or ID card to borrow equipment, the main control module finds that the identity information is correct and has the authority to borrow instruments and equipment. The identity information is recognized, and the main control module controls the push-pull electromagnet 234 to energize, so that it works and disengages from the turning tongue notch 2321, so that the lock tongue 232 releases the position restriction, and the lock tongue 232 rotates from the locked position to the unlocked position under the action of the spring 233. At this time, the key 1 is separated from the pin lock cylinder 231, and the instrument and equipment are separated from the borrowing and returning management system.

[0038] The pin lock cylinder 231 is opened or locked with a plum blossom key, and the key is a special key to ensure that one instrument corresponds to one key. When the pin lock cylinder 231 is locked by the push-pull electromagnet 234, the key cannot be pulled out, and the key can only be pulled out when the pin lock cylinder is unlocked. There is a tongue notch on the lock tongue, and the lock tongue is connected to a spring, and the other end of the spring is fixed to the housing. When the pin lock cylinder is locked, the spring is stretched, and when the pin lock cylinder is unlocked, the lock tongue is pulled back by the spring. When the pin lock cylinder is locked, the iron column of the push-pull electromagnet is stuck at the tongue notch, and there is a micro switch at the bottom of the lock tongue, which is triggered.

[0039] In a preferred embodiment of the present invention, the borrowing and returning management system also includes a network information management unit that is communicatively connected to the main control module, and the network information management unit is used to receive and manage borrowing and returning information. The main control module is used to identify the borrower's information. When the borrower's identity is identified to be correct, the push-pull electromagnet is controlled to work, and the borrowing information is recorded, and the wireless network is turned on to push the borrowing record to the network information management unit. After receiving the information returned by the network information management unit, the network is closed. The network information management unit is installed in a unified network connected to the lock body terminal unit, and can receive the information sent by the lock body terminal unit. It is convenient for the administrator to grasp the borrowing and returning time of the instrument and the power of the lock body terminal unit. More specifically, the two query buttons 24 next to the display screen can be used to check the borrowing and returning records of the equipment.

[0040] In a preferred embodiment of the present invention, the housing 3 is provided with a plurality of lock body terminal units 2, and each lock body terminal unit 2 is connected to an instrument device in a locked position.

[0041] In a preferred embodiment of the present invention, the borrowing and returning management system further comprises a buzzer. The buzzer is electrically connected to the main control module, which is a prior art in the field of buzzers and will not be described in detail here.

[0042] When borrowing, if Figure 5 As shown, when the borrowed instrument and equipment is connected to a one-to-one lock terminal, that is, one shell is only connected to one instrument and equipment, an IC card or ID card with the borrower's identity is swiped on the area of ​​the RFID card reader module. After the lock terminal unit recognizes that the borrower's identity information is incorrect, the buzzer beeps for a long time, indicating that the identity recognition fails; after the lock terminal unit recognizes that the borrower's identity information is correct, it controls the push-pull electromagnet to work so that it leaves the tongue gap, and the tongue is pulled back by the spring, which pulls the tongue to rotate. When the key is turned to the unlocked position, the key is separated from the pin lock core, and driven by the spring reel inside the easy-to-pull, the key is pulled back to the side of the easy-to-pull, and the micro switch is reset without the suppression of the tongue. The E-PAPER screen displays the borrower's name and borrowing time, and the buzzer beeps twice. The wireless networked lock terminal unit is turned on to push the borrowing information to the networked information management unit.

[0043] When the borrowed equipment is connected to a one-to-many lock terminal, such as Figure 4 As shown, when a housing is connected to multiple instruments and equipment and multiple pin lock cylinders are set on the housing, it is necessary to assign numbers to the borrowed instruments and equipment as serial numbers for identifying the instruments and equipment, press the corresponding digital button 25 on the housing, call out the RFID card reader module corresponding to the instrument and equipment, and then swipe the IC card or ID card for identity recognition. Each pin lock cylinder is also marked with corresponding numbers for distinction.

[0044] When returning equipment, Figure 6 As shown, insert the key into the pin lock hole of the corresponding pin lock cylinder. If the key on the instrument fails to pair with the lock terminal unit, the key cannot be rotated; if the key on the instrument is correctly paired with the lock terminal unit, the key can be rotated. When it is rotated to the locked position, the micro switch is triggered, and the push-pull electromagnet is stuck in the tongue notch of the lock tongue. The display screen shows the borrower's name and return time, the buzzer sounds twice, and the wireless network lock terminal unit is turned on to push the return information to the network information management unit.

[0045] The borrowing and returning method using the management system with the push-pull electromagnet 234 includes a borrowing process and a returning process:

[0046] The steps in the borrowing process include:

[0047] A1. The RFID card reader module 21 reads the borrower's identity information. When the identity information is recognized by the lock terminal unit, the lock terminal unit controls the push-pull electromagnet 234 to disengage from the lock tongue 232, and the lock tongue 232 turns to the unlocking position, and the key 1 is separated from the pin lock cylinder 231;

[0048] A2. The lock terminal unit records the borrowing information;

[0049] A3. Open the network, and the lock terminal unit transmits the borrowing information to the network information management unit;

[0050] The steps in the return process include:

[0051] B1. Insert the key 1 into the pin lock hole of the pin lock cylinder 231. If the key 1 does not turn, the return of the instrument fails and the return process ends. If the key 1 can turn, perform the following steps (B2-4) in sequence:

[0052] B2, the key 1 is turned to the locked position, the micro switch 235 is triggered, the push-pull electromagnet 234 is inserted into the tongue notch 2321, the key 1 is connected to the pin lock cylinder 231, and the distance between the instrument and the housing 1 is controlled by the flexible member;

[0053] B3, the lock terminal unit records the return information;

[0054] B4. Open the network, and the lock terminal unit transmits the return information to the network information management unit.

[0055] The method allows the key to be turned when it is returned correctly, but cannot be turned when the key does not match the lock terminal unit when returned; when borrowing instruments and equipment, it is necessary to first pass the identity verification of the lock terminal unit before turning the key, so as to first unlock the push-pull electromagnet, thus achieving double guarantee when borrowing instruments and equipment.
