Problems solved by technology

[0003] With the continuous development of the Internet and the Internet of Things technology in recent years, gradually developed a one-dimensional barcode, two-dimensional barcode, passive RFID tag as the medium to realize the electronic handover of the bank cash box. Due to the low price, the early promotion At that time, it was generally recognized by bank users, but in the actual application process, it was found that the friction and collision of the cash box during the transportation process made the one-dimensional barcode and two-dimensional barcode easy to be blurred, which caused the barcode scanner to fail to recognize normally during the handover, and became a Decoration: Passive RFID tags do not have the disadvantage of being blurred compared to barcodes, but because RFID readers have directional requirements for reading, when the cash boxes enter the vault in batches, it is easy to miss scans and incomplete reading, which must reach 100 The application of % reading success rate is a very fatal flaw, which limits the promotion of passive RFID technology in the electronic handover of bank cash boxes

Embodiment 1

[0039] Such as figure 1 As shown, a control method for a dual-frequency reader-writer used for the electronic handover of cash boxes includes the following steps:

[0040] a. Receive the initialization signal, control the chip to initialize the port and each module;

[0041] b. According to the received server-side instruction, continue to send the wake-up message, and judge whether the label is awakened message is received, if yes, then enter step c; if not, then re-enter step b;

[0042] c. Interrupt receiving, process the received message, and send the receipt information to the corresponding tag.

[0043] In this embodiment, after power-on, the power supply module obtains the 24V, 5V, and 3.3V power supply voltages required for the normal operation of the reader-writer through AC / DC conversion and DC / DC conversion; after the microcontroller software resets and runs, first Initialize the port of the chip, initialize the low-frequency transmitting module, high-frequency tr...

Embodiment 2

[0045] On the basis of embodiment 1, this embodiment also includes the following steps before performing step b:

[0046] According to the server-side instructions received, it is judged whether it is entering the vault outlet or exiting the vault outlet, and the wake-up distance is controlled according to the judgment result, and the tags within the antenna range are activated. Using a 125KHz low-frequency transmission module, it can effectively control the wake-up distance, so that it can judge whether the cash box is entering the vault outlet or exiting the vault outlet. It is especially suitable for the compact scene application of the second door of the outlet, improving the accuracy and effectiveness of judgment.

Embodiment 3

[0048]On the basis of embodiment 1, this embodiment also includes the following steps:

[0049] Store the same tag received at different times, judge its direction of entry and exit, and send the judgment result information to the server. The reader is used to locally judge the direction of the label's entry and exit, and at the same time has the function of data storage. The SD data storage module is used to store the judgment data of the label's entry and exit direction, in case the data is lost due to the failure of the Ethernet interface, it can be retransmitted when the network is normal; so that all The dual-frequency reader for the electronic handover of the cash box can better meet the business needs of bank users for the electronic handover of the cash box, and facilitate the rapid promotion and application of Internet + and Internet of Things technologies in the financial industry.

Abstract

The invention discloses a control method of a double frequency reader-writer for electronic handing over of a cash box. An initialization signal is received, and a control chip initializes ports and different modules; and according to a received server-end instruction, wake-up messages are sent continuously, whether a label waken up message is received is determined, if YES, reception is interrupted, and the received message is processed, and replay information is sent to a corresponding label. The invention also discloses a control system of the double frequency reader-writer for electronic handing over of the cash box. The control system comprises an initialization module, a message transmitting-receiving module and a message processing module. Thus, active electronic labels installed inthe cash box can be read in a batch manner efficiently and stably without omission, and handover of the bank cash box can be really electronic.

Description

technical field [0001] The invention relates to the technical field of bank cash box electronic handover monitoring, in particular to a control method and system for a dual-frequency reader-writer used for electronic cash box handover. Background technique [0002] For the sake of safety, the bank has always used manual verification of identity information and manual handover procedures for the handover of bank deposit boxes. [0003] With the continuous development of the Internet and the Internet of Things technology in recent years, gradually developed a one-dimensional barcode, two-dimensional barcode, passive RFID tag as the medium to realize the electronic handover of the bank cash box. Due to the low price, the early promotion At that time, it was generally recognized by bank users, but in the actual application process, it was found that the friction and collision of the cash box during the transportation process made the one-dimensional barcode and two-dimensional b...
