Description

Technical Field

[0001] The present invention relates to the field of radio frequency technology, and in particular to a radio frequency device and an assembly method. Background Art

[0002] Radio frequency is radio frequency current, which is the abbreviation of high-frequency alternating electromagnetic waves. In electronics theory, when alternating current passes through a conductor, an alternating electromagnetic field, i.e., electromagnetic waves, is formed around the conductor. Radio frequency signals have the ability to transmit over long distances. When the frequency of electromagnetic waves is higher than 100kHz, electromagnetic waves can propagate in the air and be reflected by the ionosphere at the outer edge of the atmosphere to form long-distance transmission. The working principle of radio frequency involves signal generation, modulation, amplification, and transmission. Signal generation is usually achieved through an oscillator inside the radio frequency transmitter to generate a radio frequency signal. Then, the signal is modulated by an radio frequency modulator to combine the information signal to be transmitted (such as audio or video signal) with the radio frequency signal to form a modulated signal. The modulated signal is further amplified by an radio frequency amplifier to increase the signal strength so that it can cover a sufficiently long distance during transmission. Finally, the amplified signal is wirelessly transmitted through an radio frequency antenna. The antenna converts the electrical signal into an electromagnetic wave signal and radiates it into space.

[0003] Currently, after the radio frequency device is assembled, it needs to perform positioning operations in the actual environment. However, since there are multiple device terminals in the indoor environment, there may be differences in the software and hardware configurations between these device terminals. These differences will cause different device terminals to obtain different RSSI values ​​of the same signal at the same time and the same location. Due to the difference in RSSI values, the device terminal will produce errors in the positioning process. This error will increase with the increase of software and hardware differences between the device terminals, resulting in inaccurate positioning results. Currently, after the radio frequency device has been used for a period of time, a certain amount of dust is easily attached to its surface. The dust attached to the antenna or signal transmission component of the radio frequency device may change the signal transmission path or absorb part of the signal energy, thereby reducing the signal quality, which may lead to the problem of shortened communication distance and reduced signal stability of the radio frequency device. Most radio frequency devices do not have an automatic cleaning function, which brings inconvenience to the staff. Summary of the invention

[0047] S2. After data collection is completed, the collected data is preprocessed, the collected data is cleaned, noise and outliers are removed, the data is processed using filtering technology, and then the key features of the RF signal are extracted, the signal strength and phase are extracted, and the signal strength and phase are used as input data;

[0048] S3. Build a BP neural network model, determine the network structure, and design the structure of the BP neural network, including the input layer, hidden layer, and output layer. The number of input layer nodes should be equal to the number of features, and the number of output layer nodes depends on the number of variables to be predicted. Then initialize the weights and biases, and randomly initialize the weights and bias parameters of the neural network.

[0049] S4, based on the optimization of the artificial bee colony algorithm, define the parameters of the artificial bee colony algorithm, set the parameters of the bee colony size and the number of iterations, define the evaluation function of the honey source, execute the artificial bee colony algorithm, initialize the bee colony, randomly generate the initial honey source, record the best honey source found in each iteration, and then update the neural network parameters, use the best honey source found by the artificial bee colony algorithm as the new weight and bias of the neural network, input the training data into the neural network, calculate the output result, calculate the error between the actual output and the expected output, adjust the weight and bias of the neural network according to the error, repeat the forward propagation and back propagation process until the predetermined number of iterations is reached, and complete the neural network model. The steps of establishing the neural network model include:

[0050] S4.1. Initially construct the BP neural network, obtain the initial weights and thresholds, i.e., the initialization values ​​of the bee colony, set the population size, the number of nectar sources SN, the maximum number of iterations, and the control parameter limit;

[0051] S4.2, in the hired bee stage, the nectar source solution is sought, and in the follower bee stage, the fitness value of the nectar source solution is calculated, and the probability of each nectar source being mined is calculated, and then the roulette method is used to select the nectar source mining results, and the parameter trial is set for the nectar source. When the nectar source is retained, trial is 0, otherwise it is increased by 1;

[0052] S4.3, exploration bee stage, judge whether the number of times the nectar source is mined is greater than the limit. If so, it means that this position has fallen into the local optimum, and the exploration bee stage will be started. When the maximum number of iterations is reached, the optimal result will be output;

According to the optimal solution of the artificial bee colony, the initial parameters of the BP neural network, i.e., the optimal initial weight threshold, are set, the number of nodes in the input layer, hidden layer, and output layer of the network is determined, the training sample data is transferred from the input layer to the hidden layer and the output layer, the activation value of each node is calculated, and the Sigmoid activation function is used to convert the activation value into an output value;

[0055] S5. The staff uses an independent test data set to test the trained neural network, record the test results, evaluate the positioning accuracy, and then calculate the positioning error. After analyzing the results, the model is further optimized. After optimization, the staff applies the trained BP neural network model to the assembly process of the RF equipment and uses the model to locate the RF signal to complete the assembly of the RF device. Later, when the RF device is in use, the staff monitors the positioning effect in real time and regularly maintains and updates the model.

[0056] Working principle: When the radio frequency device is put into operation after being assembled, if the staff needs to clean the dust on the surface of the mounting shell 2, the staff only needs to turn on the dual-axis motor 62 to make the movable plates 4 on the left and right sides swing, and the anti-static fan 5 will blow the anti-static wind to the surface above and on the left and right sides of the mounting shell 2 to perform anti-static treatment on the surface of the mounting shell 2. After the anti-static treatment is completed, the staff can turn on the first motor 81 at the rear, so that the first cleaning brushes 10 on the left and right sides move toward the edge of the mounting shell 2. At this time, the second cleaning brushes 14 on the left and right sides move upward. When the first cleaning brush 10 pushes the dust on the top of the mounting shell 2 to the edge of the top of the mounting shell 2, the staff changes the rotation direction of the output shaft of the first motor 81, so that The first cleaning brush 10 is moved back to its original position, and the second cleaning brushes 14 on the left and right sides are moved downward, and the dust on the surface of the mounting shell 2 is scraped off by the second cleaning brush 14, so that the mounting shell 2 is kept clean as a whole. When the staff needs to comb the line behind the RF device, the staff can pass the line of the RF device through the wire clip 18 and pass the line through the through hole on the surface of the combing plate 195. After the line is passed, the staff can turn the knob 194 to keep the line of the RF device taut to avoid loose lines and entanglement. When the RF device encounters vibration during operation, the upper buffer plate 214 will move, and the internal components of the RF device inside the mounting shell 2 are protected by the second shock-absorbing spring 217 and the first shock-absorbing spring 213.
