Description

Technical Field

[0001] The invention belongs to the technical field of wireless communication, and more specifically, particularly relates to a remote control method for wirelessly releasing multiple alarms. Background Art

[0002] In today's retail environment, anti-theft measures are essential to protect the safety of goods and maintain the normal operation of stores. However, traditional anti-theft systems have many problems in practical applications.

[0003] With the continuous development of the retail industry, retail stores often use different types of anti-theft devices to meet different anti-theft needs. These anti-theft devices usually come from different manufacturers and have independent and inconsistent alarm receiving instructions. As a result, during store operations, once an anti-theft device sounds an alarm, sales staff need to hold multiple different remote controls and try to cancel the alarm one by one, which is extremely cumbersome and inefficient.

[0004] This traditional way of removing the alarm not only seriously affects the shopping experience of consumers, but also makes consumers feel irritated and uneasy due to the continuous harsh alarm sound. At the same time, it also greatly distracts the attention of sales staff, making it impossible for them to devote themselves to the promotion activities, which has a certain negative impact on the sales performance of the store.

[0005] In addition, the need to operate multiple remote controls increases the difficulty of sales staff's work and the probability of error. In an emergency, the alarm may not be released in time, causing unnecessary confusion and losses. Moreover, the management and maintenance of multiple remote controls is also more complicated, increasing the store's operating costs.

[0006] Therefore, in order to solve the problems of cumbersome and inefficient alarm cancellation process caused by inconsistent alarm reception instructions of multiple burglar alarm devices in retail stores, an innovative technical solution is urgently needed that can enable one remote control to cancel the alarms of multiple different burglar alarms at the same time, improve store operation efficiency, and enhance consumer experience. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a remote control method for wirelessly releasing multiple alarms to solve the above problems.

[0008] The invention discloses a remote control method for wirelessly releasing multiple alarms, comprising a remote controller, wherein the remote controller is composed of a shell, a main board and a battery, wherein the main board is equipped with an RF antenna, an RF circuit and a single-chip microcomputer, and the battery of the remote controller provides power for the circuit board.

[0009] Preferably, when the remote controller is working, the A anti-theft device receiving instruction is sent first, and the B anti-theft device receiving instruction is sent synchronously after 100-500ms, and so on, and multiple anti-theft device receiving instructions are sent simultaneously to cancel the alarms of multiple different anti-theft device hosts.

[0010] Preferably, the radio frequency transmitting chip in the remote control is a low-power, high-bandwidth wireless digital communication module designed specifically for the 2.4G wireless application frequency band.

[0011] Preferably, the RF transmitter chip has a built-in MCU and a charging management circuit, and has the characteristics of low cost, small size and stable operation.

[0012] Preferably, the key input module of the remote control controls the P14 signal through a button, and after the P14 signal enters the single-chip microcomputer, the control signal is transmitted through the radio frequency circuit and the RF antenna.

[0013] Preferably, the control signal operates in a multi-frequency band within the RF carrier frequency range of 2400 MHz to 2483.5 MHz, flexibly configuring various communication channels and switching frequencies quickly to meet the requirements of a frequency hopping system.

[0014] Preferably, the control signal has a data buffer, supports burst data transmission, and has automatic response reception and retransmission processing functions.

[0015] Preferably, the control signal is built into the EPROM, and the EPROM data space can be modified arbitrarily.

[0016] Preferably, the wireless transmission of the control signal supports 250Kbps and 2Mbps rates, achieves high data throughput by using FSK / GFSK modulation, and has 5 to -35dBm power output control.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Improve store operation efficiency: The wireless remote control method for deactivating multiple alarms of the present invention significantly improves the operation efficiency of retail stores. The traditional multi-remote control operation method requires sales staff to spend a lot of time testing the remote controls one by one to deactivate the alarms, which is not only cumbersome, but also easily leads to untimely processing and affects normal business. The integrated remote control of the present invention only needs to press a button once to send a deactivation command to multiple different anti-theft devices at the same time, greatly shortening the time to process alarms. This enables sales staff to quickly resolve alarm problems and devote more time and energy to promotional activities, thereby improving the overall operation efficiency of the store. At the same time, quickly deactivating the alarm can also reduce the interference to customers caused by the continuous alarm sound, maintain a good shopping environment, and help improve customer satisfaction and loyalty.

[0019] 2. Improve consumer shopping experience: In the past, the untimely and cumbersome processing of burglar alarms would bring a bad shopping experience to consumers in the store. The harsh alarm sound may cause consumers to be nervous and uncomfortable, and the long processing process may also interrupt the consumer's shopping process. The remote control method of the present invention can quickly release the alarm, reduce the impact of the alarm sound on consumers, and create a quieter and more comfortable shopping environment for consumers. Consumers can focus more on purchasing goods without being bothered by frequent alarm interference. This helps to improve consumers' favorability towards the store and increase their willingness to patronize again.

[0020] 3. Reduce labor costs: In the traditional anti-theft device management model, in order to respond to different alarm reception instructions, stores often need to equip sales staff with multiple remote controls and provide them with complex operation training. This not only increases the equipment procurement cost, but also consumes a lot of human training resources. The single remote control solution of the present invention greatly simplifies the operation process and reduces the training requirements for sales staff. One sales staff can easily deal with the alarm release of multiple anti-theft devices, reducing manpower investment. At the same time, due to the improved convenience of operation, the time waste and possible economic losses caused by operational errors are reduced, further reducing the operating costs of the store.

[0021] 4. Enhance the reliability of the anti-theft system: The present invention improves the reliability and accuracy of command transmission through strict command transmission timing control, adding preambles and check codes, etc., ensuring that each anti-theft device can accurately receive the release command. This effectively avoids the situation where the anti-theft device cannot release the alarm due to command transmission errors or loss, and enhances the overall reliability of the store's anti-theft system. Even in a complex electromagnetic environment, by adopting anti-interference measures and optimized hardware design, the remote control can work stably to ensure the normal operation of the anti-theft system. In addition, the encryption authentication mechanism further enhances the security of the system, prevents interference and malicious release of illegal commands, and provides more reliable protection for the property safety of the store.

[0022] 5. Flexible adaptation to business changes: Over time, stores may replace or add different types of anti-theft devices, or adjust anti-theft strategies. The remote control of the present invention has good compatibility and scalability, and can add new anti-theft device receiving instruction formats and control logic through software upgrades. The reserved hardware interface and expansion space are also convenient for adding new functional modules. This enables the remote control to easily adapt to changes and developments in store business without the need for frequent equipment replacement, reducing equipment update costs. At the same time, sales staff can personalize the remote control by setting buttons or configuring software, such as adjusting the instruction sending interval, selecting the anti-theft device to be released first, etc., to meet the needs of different scenarios, further improving the flexibility and adaptability of the system.

[0023] 6. Facilitate system integration and intelligent management: The remote control of the present invention can be integrated with the security monitoring system, inventory management system, etc. in the store to achieve more intelligent store management. When the remote control releases the burglar alarm, it can automatically record the relevant information into the security monitoring system to provide data support for subsequent security analysis and management. At the same time, integration with the inventory management system can trigger the update of the corresponding commodity inventory to ensure the accuracy and timeliness of inventory data. This system integration not only improves the efficiency and accuracy of store management, but also provides more comprehensive information for data analysis and decision-making, which helps store managers better understand the store's operating conditions and make more scientific decisions.

[0028] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] See also Figure 1-Figure 4 The present invention provides a remote control method for wirelessly disabling multiple alarms. The remote control method for wirelessly disabling multiple alarms is intended to solve the cumbersome alarm disabling process caused by inconsistent alarm receiving instructions of multiple anti-theft devices in retail stores. Through innovative software and hardware design, a convenient function of a remote control being able to simultaneously disabling multiple different anti-theft device alarms is realized, which improves store operation efficiency and consumer experience. The remote control includes a housing, a main board, and a battery. The main board is equipped with an RF antenna, an RF circuit, and a single-chip microcomputer. The battery of the remote control provides power for the circuit board.

[0030] The shell is made of high-strength, wear-resistant plastic material with good insulation and anti-interference capabilities. Its design shape conforms to ergonomics, making it easy for sales staff to hold and operate. The shell not only provides physical protection for the internal circuit board to prevent it from being eroded by external collisions, dust and moisture, but also plays a role in shielding external electromagnetic interference, ensuring that the internal circuit of the remote control can work stably and reliably.

[0031] The RF antenna adopts a miniaturized, high-gain PCB antenna design, and its operating frequency covers the 2.4GHz frequency band. This antenna has good omnidirectional radiation characteristics, and can effectively propagate RF signals in all directions, ensuring stable and reliable communication between the remote control and the anti-theft device, without being restricted by the direction and position of the remote control. In order to improve the performance of the antenna, the shape, size and routing of the antenna are carefully optimized during the PCB wiring process to reduce signal reflection and loss. At the same time, a ground shielding layer is set around the antenna to further reduce the impact of external interference on the antenna performance.

[0032] The RF circuit consists of two parts: the RF transmitter and the RF receiver. The RF transmitter uses an efficient power amplifier, which can amplify the weak electrical signal output by the single-chip microcomputer to a sufficient power level to meet the needs of long-distance transmission. At the same time, in order to ensure the quality and spectrum purity of the transmitted signal, a filter circuit and an impedance matching circuit are also used to filter and optimize the transmitted signal. The RF receiver uses a highly sensitive low-noise amplifier and mixer, which can amplify and down-convert the received weak RF signal into an intermediate frequency signal that can be processed by the single-chip microcomputer. At the front end of the receiver, a bandpass filter is also set to filter out out-of-band interference and noise and improve the signal-to-noise ratio of the received signal. In order to ensure the stability and reliability of the RF circuit, a high-precision crystal oscillator is used as the clock source to provide an accurate operating frequency for the RF transceiver. At the same time, a power management module is also set in the circuit to perform separate filtering and voltage stabilization on the power supply of the RF part to reduce the impact of power supply fluctuations on RF performance.

[0033] The single-chip microcomputer uses a high-performance, low-power microcontroller with rich I / O ports and powerful computing power. The single-chip microcomputer is responsible for processing the signal from the key input module, generating the corresponding control instructions, and sending the instructions through the RF circuit. It integrates a large-capacity Flash memory and SRAM to store control programs and data. Through programming, the working mode and parameters of the single-chip microcomputer can be flexibly configured to meet different anti-theft device control requirements. In order to improve the anti-interference ability of the single-chip microcomputer, a decoupling capacitor is set between its power pin and ground pin to reduce the influence of power supply noise. At the same time, in the program design, a watchdog timer and error handling mechanism are also used to ensure that the single-chip microcomputer can automatically resume normal operation when it is disturbed or abnormal.

[0034] The battery uses a rechargeable lithium battery as a power source, which has a high energy density and a long service life. The battery is connected to an external power source through a specially designed charging management circuit to achieve safe and fast charging. The charging management circuit can monitor the charging status of the battery and automatically stop charging when the battery is full to prevent overcharging from damaging the battery. At the same time, it can also send an alarm signal to the microcontroller when the battery power is too low to remind the user to charge in time.

[0035] When the salesperson presses the alarm release button on the remote control, the MCU first reads the pre-stored A anti-theft device receiving command. Then, through the RF circuit and RF antenna, the command is sent out with priority using a wireless signal in the 2.4GHz frequency band. After the transmission is completed, the MCU starts the internal timer, waits for 100 to 500ms (the specific time can be set through software according to actual needs), and then reads and sends the B anti-theft device receiving command. In the same way, the subsequent anti-theft device receiving commands are sent in sequence until all the anti-theft device commands that need to be released are sent.

[0036] In order to ensure that each anti-theft device can accurately receive the command, the timing of command transmission is strictly controlled. During the waiting time between sending each command, the microcontroller continuously monitors the status of the RF circuit to ensure that the previous command is sent and the wireless channel is idle before sending the next command. At the same time, in order to prevent command conflicts and interference, a specific preamble and check code are added when sending each command to improve the reliability and accuracy of the command.

[0037] The sent anti-theft device receiving command is encoded using a specific encoding method to improve the confidentiality and anti-interference ability of the command. Common encoding methods include pulse code modulation (PCM), pulse width modulation (PWM), etc. The encoded command signal is then modulated to a 2.4GHz carrier through modulation methods such as frequency shift keying (FSK) or Gaussian frequency shift keying (GFSK) for transmission.

[0038] After the remote control is powered on, the software first performs system initialization, which includes initializing the internal registers of the microcontroller, configuring the working mode of the I / O port, setting the working parameters of the RF circuit (such as frequency, power, channel, etc.), and reading the anti-theft device receiving instructions and related configuration information stored in Flash.

[0039] The software continuously scans the key input module to detect whether any key is pressed. When the alarm release button is detected to be pressed, the corresponding processing program is triggered. In the processing program, the first anti-theft device receiving instruction to be sent is determined according to the preset anti-theft device priority order, and then the remote control transmission instruction generation and sending logic is followed.

[0040] The software is responsible for controlling the sending and receiving of the RF circuit. When sending a command, the coded and modulated command data is passed to the RF circuit and the sending process is started. When receiving the feedback signal from the anti-theft device, the signal is received and demodulated through the RF circuit, and then the received data is analyzed and processed.

[0041] The software stores the pre-stored receiving instructions, configuration information, and operation records of each anti-theft device in the Flash memory of the microcontroller. At the same time, it also has the function of data update and management. For example, when adding a new anti-theft device or modifying the instructions of an existing anti-theft device, the stored data can be modified and saved accordingly.

[0042] During operation, the software can detect and handle various possible errors, such as command sending failure, reception timeout, data verification error, etc. When an error occurs, the software will take corresponding recovery measures according to the error type, such as resending the command, switching to an alternate channel, resetting the system, etc., to ensure that the remote control can continue to work stably.

[0043] Before using this remote control, you need to adapt the various anti-theft devices in the store. This includes obtaining the receiving command format, frequency and other parameters of each anti-theft device, and entering these parameters into the remote control software for configuration. For some special anti-theft devices, additional hardware modification or interface adaptation may be required to ensure that the remote control is compatible with them.

[0044] The salesperson can personalize the remote control through the setting button on the remote control or the dedicated configuration software. For example, they can set the interval time for sending each immobilizer command, select the immobilizer to be released first, adjust the working frequency and power of the remote control, etc. These setting information will be saved in the non-volatile memory of the remote control so that it can be directly loaded the next time it is used.

[0045] Install the remote control in a location in the store that is easy to operate, such as the cash register or the work area of ​​the salesperson. After the installation is completed, debug the system. This includes testing whether the communication between the remote control and each anti-theft device is normal, whether the command release effect is as expected, etc. During the debugging process, if any problems are found, they can be solved by adjusting the parameters of the remote control or checking the settings of the anti-theft device.

[0046] When a certain anti-theft device in the store detects an abnormal situation and triggers an alarm, a specific alarm sound and signal will be emitted.

[0047] After hearing the alarm sound, the salesperson picks up the remote control and presses the alarm release button. The remote control sends release instructions to each related anti-theft device in turn according to the preset working logic.

[0048] After sending the release command, the remote control will wait for a certain period of time to receive the feedback signal from the immobilizer. If the feedback signal indicates that the immobilizer has successfully released the alarm, the remote control will display the corresponding prompt information (such as flashing indicator lights or screen display). If no feedback signal is received within the specified time, or the feedback signal indicates that the release has failed, the remote control will send the release command again, or prompt the salesperson to take other measures (such as manually checking the immobilizer).

[0049] In order to expand the signal coverage of the remote control in large retail stores, methods such as increasing RF transmission power, optimizing antenna design, and using signal repeaters can be adopted. At the same time, the operating frequency and channel can be adjusted to avoid possible interference sources and improve the signal's penetration ability and propagation distance.

[0050] With the continuous development of anti-theft technology, new types of anti-theft devices may appear. In order to make the remote control compatible with more types of anti-theft devices, new anti-theft device receiving instruction formats and control logic can be added through software upgrades. At the same time, a certain hardware interface and expansion space are reserved so that new functional modules can be added when necessary.

[0051] In order to achieve more intelligent store management, the remote control can be integrated with the store's security monitoring system, inventory management system, etc. For example, when the remote control releases the burglar alarm, it can automatically record the relevant information into the security monitoring system, or trigger the inventory management system to update the inventory of the corresponding goods.

[0052] Based on the feedback from sales staff and actual usage, the operation interface and function layout of the remote control are continuously optimized. For example, shortcut keys are added, common anti-theft device combinations are set, and sound and vibration prompts are provided to improve the convenience and efficiency of operation.

[0053] In order to prevent illegal users from obtaining and simulating the remote control signal, the received command of the anti-theft device is encrypted. At the same time, an authentication mechanism is set up on the anti-theft device side. Only after receiving a legal encrypted command and passing the authentication, the alarm release operation is executed.

[0054] Anti-interference measures such as frequency hopping technology and spread spectrum technology are used to improve the working stability of the remote control in complex electromagnetic environments. In addition, in the hardware design, filter circuits and shielding layers are added to reduce the impact of external interference on the remote control.

[0055] In order to ensure that the remote control can still work normally when the battery is low or there is a sudden power outage, an efficient power management technology is used to monitor the battery power in real time and remind the user to charge in time when the power is too low. At the same time, it is equipped with a backup power supply or super capacitor to maintain short-term operation when the main power fails to ensure the completion of the current alarm release operation.

[0056] A fault detection mechanism is set up in the software to perform regular self-checks on the remote control's hardware and software. When a fault is detected, appropriate recovery measures can be automatically taken, such as restarting the system, restoring default settings, etc. If the fault cannot be recovered by itself, the remote control will display a fault code to prompt the user to repair it.

[0057] Regularly inspect and maintain the remote control, including cleaning the casing, checking the battery level, testing button functions, detecting RF signal strength, etc. At the same time, regularly update the remote control software to fix possible vulnerabilities and optimize performance.

[0058] There are two ways to upgrade: online upgrade and local upgrade. Online upgrade connects the remote control to the network, automatically detects and downloads the latest software version for installation. Local upgrade requires the user to download the upgrade file to the computer, connect the remote control to the computer via a data cable, and perform manual upgrade operations.

[0059] This wireless remote control method for disabling multiple alarms realizes the convenient control of multiple anti-theft devices with one remote control through carefully designed hardware and software. From the hardware composition and working logic of the remote control to the design and implementation of the software, and then to the operation process and performance optimization in practical applications, the actual needs and usage scenarios of retail stores are fully considered. Through encryption authentication, anti-interference, power management and other measures, the safe and reliable operation of the system is guaranteed. At the same time, a complete maintenance and upgrade plan is provided to ensure that the system can continue to adapt to the ever-changing market needs and technological development. This innovative solution will greatly improve the operating efficiency and service quality of commodity retail stores, and bring a new experience to the anti-theft management of stores.
