[0049] Example 1

[0050] Reference Figure 1The diagram shows a structural schematic of a first type of dual-frequency positioning device provided in an embodiment of the present invention. The dual-frequency positioning device provided in this embodiment of the present invention includes a dual-frequency positioning chip 100, which includes a main chip 110 and a slave chip 120. The main chip 110 includes a first signal receiving module 111, and the slave chip 120 includes a second signal receiving module 121.

[0051] The master chip 110 is communicatively connected to the slave chip 120;

[0052] The main chip 110 is used to send a synchronization receiving request to the slave chip 120 and receive a first positioning signal based on the first signal receiving module 111.

[0053] The slave chip 120 is used to receive the second positioning signal synchronously with the master chip 110 based on the second signal receiving module 121 when it receives the synchronous receiving request, wherein the first positioning signal and the second positioning signal are signals of different frequencies.

[0054] The main chip 110 is also used to perform dual-frequency positioning calculations based on the first positioning signal and the second positioning signal to obtain the dual-frequency positioning signal.

[0055] Specifically, the dual-frequency positioning chip in this embodiment includes two single-frequency positioning chips, namely a master chip 110 and a slave chip 120. The master chip 110 receives positioning signals of different frequencies (i.e., a first positioning signal and a second positioning signal) through a first signal receiving module 111 and a second signal receiving module 121, respectively. Dual-frequency positioning calculations are then performed on the first and second positioning signals to obtain more accurate dual-frequency positioning information. In other words, to achieve dual-frequency signal reception and positioning of the single-frequency chip, this embodiment employs a dual single-frequency signal setup. The two single-frequency chips are used to receive positioning signals of different frequencies, and when they receive positioning signals synchronously, a dual-frequency positioning signal is calculated based on the two single-frequency positioning signals.

[0056] It should be noted that the main chip 110 and the slave chip 120 may be the same or different chips. In specific examples, the main chip 110 and the slave chip 120 in this embodiment of the invention may be Beidou chips or other satellite navigation and positioning chips.

[0057] Furthermore, the master chip 110 has the ability to control the slave chip 120. Therefore, in this embodiment of the invention, the master chip 110 controls the slave chip 120 to achieve synchronous signal reception. Specifically, the master chip 110 is used to send a synchronous reception signal to the slave chip 120, establishing a synchronous relationship between the master and slave chips, thereby enabling synchronous reception of positioning signals. In practical applications, since positioning systems generally perform positioning by receiving L1 carrier signals and L2 carrier signals, in one feasible manner, in this embodiment of the invention, the first positioning signal received by the master chip 110 is either an L1 carrier signal or an L2 carrier signal, while the slave chip 120 receives the corresponding L2 carrier signal or L1 carrier signal.

[0058] In addition, the dual-frequency positioning device also includes a storage module 130, and the main chip 110 and the slave chip 120 are both connected to the storage module 130. The storage module 130 includes a first storage unit 131 and a second storage unit 132.

[0059] The main chip 110 is used to store the first positioning signal in the first storage unit 131 after receiving the first positioning signal, so as to facilitate the subsequent calculation of the first positioning signal by the main chip to obtain the first coordinate signal.

[0060] The slave chip 120 is used to store the second positioning signal in the second storage unit 132 after receiving the second positioning signal, so that the slave chip can calculate the second positioning signal to obtain the second coordinate signal.

[0061] The main chip 110 is also used to read the second coordinate signal in the second storage unit 132 and store the read second positioning signal in the first storage unit 131. Then the main chip 110 can perform dual-frequency calculation based on the first coordinate signal and the second coordinate signal to obtain the dual-frequency positioning signal.

[0062] Specifically, after receiving the first positioning signal and the second positioning signal from the main chip 110 / slave chip 120, the main chip 110 stores the received first positioning signal in the first storage unit 131 of the storage module 130, and the slave chip 120 stores the received second positioning signal in the second storage unit 132 of the storage module 130. The main chip 110 and slave chip 120 can calculate the corresponding first coordinate signal and second coordinate signal based on these two positioning signals, respectively. The main chip 110 accesses the second storage unit 132 to read the second coordinate signal and stores the second positioning signal in the first storage unit 131. In this way, the main chip 110 can perform dual-frequency positioning calculations by reading the first and second positioning signals from the first storage unit.

[0063] Specifically, the signals received by the main chip 110 and the slave chip 120 may contain errors due to ionospheric delay. Therefore, the first and second coordinate signals calculated separately are still simple single-frequency coordinate signals with significant errors. However, because the first and second positioning signals have different frequencies, their ionospheric delays are different. Therefore, the first and second coordinate signals can be combined for dual-frequency calculation. That is, after reading the second coordinate signal, the main chip 110 will use a preset algorithm to perform dual-frequency positioning calculation on the first and second coordinate signals and store the dual-frequency positioning coordinates calculated from the second coordinate signal in the first storage unit 131. As a result, the signal in the first storage unit 131 is a corrected signal with higher accuracy, thus making the positioning signal more accurate.

[0064] It is understood that the preset algorithm in the embodiments of the present invention is set according to the actual situation. For example, in one feasible mode, the preset algorithm is the BDS (Beidou Navigation Satellite System) / GPS (Global Positioning System) dual-frequency RTK (Real Time Kinematic) algorithm.

[0065] Based on this, the embodiments of the present invention realize the reception of dual-frequency signals and positioning calculation based on two single-frequency chips, and realize the multiplexing of single-frequency chips; and, compared with the positioning completed by a single-frequency chip, the positioning accuracy of the dual-frequency positioning device provided by the embodiments of the present invention is improved; moreover, since the industrial cost of single-frequency chips is low, the embodiments of the present invention can also effectively reduce the industrial cost of dual-frequency signal reception and dual-frequency positioning device.

[0066] Optionally, in one feasible embodiment of the present invention, please refer to the following: Figure 2 The diagram shows a second type of dual-frequency positioning device provided by an embodiment of the present invention. In this feasible mode, the storage module 130 is implemented based on a storage chip.

[0067] The main chip 110 also includes a first memory chip control module 112, and the slave chip 120 also includes a second memory chip control module 122.

[0068] The first signal receiving module 111 is connected to the first memory chip control module 112, and the second signal receiving module 121 is connected to the second memory chip control module 122.

[0069] Both the first memory chip control module 112 and the second memory chip control module 122 are connected to the memory module 130.

[0070] That is, in this feasible manner, embodiments of the present invention can utilize, for example, a flash memory chip as the storage module 130. Therefore, both the master chip 110 and the slave chip 120 are provided with controllers (i.e., a first storage chip control module 112 and a second storage chip control module 122) for controlling the storage chip / storage module 130. It is easy to understand that the first storage chip control module 112 and the second storage chip control module 122 are used to perform signal read and write operations corresponding to the storage module.

[0071] Subsequently, after the first signal receiving module 111 in the main chip 110 receives the first positioning signal, the first storage chip control module 112 stores the first positioning signal in the first storage unit 131 in the storage module 130. After receiving the second positioning signal from the second signal receiving module 121 in the chip 120, the second storage chip control module 122 stores the second positioning signal in the second storage unit 132 in the storage module 130. Finally, the first storage chip control module 112 reads the second positioning signal from the second storage unit 132 into the first storage unit 131.

[0072] Furthermore, it is easy to understand that the storage chip in the embodiments of the present invention can be any type of chip used to implement storage functions. For example, in one feasible mode, the storage chip is a flash memory chip. Therefore, the first storage chip control module 112 and the second storage chip control module 122 are both flash controllers.

[0073] Optionally, to avoid unexpected errors during read / write operations and to ensure the safe storage of signals, in one feasible method provided in this embodiment of the invention, please refer to [specific details missing]. Figure 3 The diagram shows a third type of dual-frequency positioning device provided by an embodiment of the present invention. In this feasible mode, the main chip 110 includes a data storage unit 113, and the first storage unit 131 pre-stores a first initialization program.

[0074] The main chip 110 is also used to exit the reset state after power-on, control the slave chip 120 to enter the reset state, and read the first initialization program in the first storage unit 131 into the data storage unit 113.

[0075] The main chip 110 is also used to allocate read and write permissions for the first storage unit and the second storage unit to the main chip and the slave chip based on the first initialization program in the data storage unit 113.

[0076] Specifically, read and write permissions for the first storage unit 131 and the second storage unit 132 can be assigned to the main chip 110, and read and write permissions for the second storage unit 132 can be assigned to the slave chip 120, and then the slave chip 120 can be controlled to exit the reset state.

[0077] In other words, for security reasons, this embodiment of the invention prevents the slave chip 120 from accessing the first storage unit 131, reducing the slave chip's privileges and thus reducing data read errors, ensuring the stability of system operation. Therefore, before the master chip 110 and slave chip 120 perform signal reception, during the power-on initialization phase, the read and write permissions of the first storage unit 131 and the second storage unit 132 are allocated, thereby preventing the slave chip 120 from accessing the first storage unit 131 and ensuring that the slave chip 120 can only read and write data in the second storage unit 132.

[0078] Specifically, in this embodiment of the invention, a first initialization program pre-stored in the first storage unit 131 is used to enable the main chip 110 to read the first initialization program into its own data storage unit 113 after power-on and disconnection from reset. This allows the main chip to perform read / write permission allocation operations for the first storage unit 131 and the second storage unit 132, while the slave chip can only read / write the second storage unit 132.

[0079] Therefore, the embodiments of the present invention ensure the data security in the first storage unit 131 and the second storage unit 132, eliminate the risk of modifying the first positioning signal from the chip 120, and avoid data leakage.

[0080] Optionally, in one feasible embodiment of the present invention, the first storage unit 131 further stores a second initialization program and main chip configuration data, and the second storage unit 132 stores a third initialization program and slave chip configuration data.

[0081] The main chip 110 is also used to read the second initialization program and the main chip configuration data in the first storage unit 131 to complete its own initialization;

[0082] The slave chip 120 is also used to read the third initialization program and the slave chip configuration data in the second storage unit 132 to complete its own initialization.

[0083] That is, in addition to using the first storage unit 131 to complete the allocation of read and write permissions, the embodiments of the present invention also use the second initialization program and main chip configuration data pre-stored in the first storage unit 131 to complete the initialization of the main chip 110, and use the third initialization program and slave chip configuration data pre-stored in the second storage unit to complete the initialization of the slave chip 120.

[0084] Optionally, in one feasible embodiment of the present invention, the dual-frequency positioning chip 100 further includes a first antenna 140 and a second antenna 150, the main chip 110 further includes a first communication module 114 and a first microprocessor module 115, and the slave chip 120 further includes a second communication module 123 and a second microprocessor module 124.

[0085] The first signal receiving module 111 is electrically connected to the first antenna 140, and both the first signal receiving module and the first communication module 114 are electrically connected to the first microprocessor module 115. The first microprocessor module 115 is electrically connected to the storage module 130.

[0086] The second signal receiving module 121 is electrically connected to the second antenna 150. The second signal receiving module 121 and the second communication module 123 are both electrically connected to the second microprocessor module 124. The second microprocessor module 124 is electrically connected to the storage module 130.

[0087] The master chip 110 and the slave chip 120 are connected through the first communication module 114 and the second communication module 123.

[0088] That is, in this embodiment of the invention, the location signal is received based on the first antenna 140, the second antenna 150, the first signal receiving module 111 and the second signal receiving module 121, while the communication between the main chip 110 and the slave chip 120 is completed based on the first communication module 114 and the second communication module 123.

[0089] It should be noted that, Figure 3 Although the first microprocessor module 115 and the second microprocessor module 124 are electrically connected to the storage module through the first storage chip control module 112 and the second storage chip control module 122, respectively, it should be understood that if the first storage chip control module 112 and the second storage chip control module 122 are not used, the first microprocessor module 115 and the second microprocessor module 124 will be directly electrically connected to the storage module 130.

[0090] It should also be noted that, in the embodiments of the present invention, the first microprocessor module 115 and the second microprocessor module 124 are respectively used to control the operating logic of various devices and modules in the main chip and the slave chip.

[0091] Optionally, in one feasible embodiment of the present invention, the main chip 110 is further configured to send a signal storage location acquisition request to the slave chip 120;

[0092] When the slave chip 120 receives a request to retrieve the signal storage location, it sends the storage location of the second positioning signal to the master chip 110.

[0093] The main chip 110 is also used to read the second positioning signal in the second storage unit 132 according to the storage location, and store the read second positioning signal in the first storage unit 131.

[0094] That is, in this embodiment of the invention, the slave chip 120 will not actively forward the received second positioning signal to the master chip 110, but will only inform the master chip 110 of the storage location of the second positioning signal in the second storage unit 132. The master chip 110 can read the second positioning signal by obtaining the storage location of the second positioning signal from the slave chip 120.

[0095] Therefore, this embodiment of the invention avoids the data / signal leakage problem that may be caused by chip 120, and ensures the security of the positioning signal.

[0096] Example 2

[0097] Corresponding to the dual-frequency positioning device provided in Embodiment 1 of the present invention, Embodiment 2 of the present invention also provides a dual-frequency positioning method, as described below. Figure 4 The diagram illustrates a flowchart of a dual-frequency positioning method provided in an embodiment of the present invention. This dual-frequency positioning method is applied to the main chip in a dual-frequency positioning device as shown in Embodiment 1. The method includes:

[0098] Step S100: Establish a communication connection between the main chip and the slave chip in the dual-frequency positioning device, and synchronize the main chip and the slave chip.

[0099] Step S200: Receive a first positioning signal and a second positioning signal, wherein the first positioning signal is received by the main chip and the second positioning signal is received by the slave chip.

[0100] Step S300. Perform dual-frequency positioning calculation based on the first positioning signal and the second positioning signal to obtain a dual-frequency positioning signal, wherein the dual-frequency positioning calculation is performed by the main chip.

[0101] When performing dual-frequency positioning calculations, a first coordinate signal can be calculated based on the first positioning signal, and a second coordinate signal can be calculated based on the second positioning signal. Then, a dual-frequency calculation is performed on the first coordinate signal and the second coordinate signal according to a preset algorithm to obtain the dual-frequency positioning signal.

[0102] That is, the dual-frequency positioning method of Embodiment 2 of the present invention is based on the dual-frequency positioning device provided in Embodiment 1, and completes the reception of dual-frequency signals through two single-frequency chips, thereby realizing the multiplexing of single-frequency chips; and, compared with completing positioning through a single-frequency chip, the positioning accuracy of the dual-frequency positioning device provided in the embodiment of the present invention is improved; moreover, since the industrial cost of single-frequency chips is low, the embodiment of the present invention can also effectively reduce the industrial cost of dual-frequency signal reception and dual-frequency positioning device.

[0103] Furthermore, it is understood that the method steps and beneficial effects involved in Embodiment 1 of the present invention can be correspondingly set in Embodiment 2, and the same technical effects can be achieved. To avoid repetition, they will not be described again here.

[0104] Example 3

[0105] like Figure 5 As shown, this embodiment provides a dual-frequency positioning chip 100, which includes a master chip 110 and a slave chip 120.

[0106] The main chip 110 includes a first signal receiving module 111, and the slave chip includes a second signal receiving module 121.

[0107] The master chip 110 is communicatively connected to the slave chip 120;

[0108] The main chip is used to send a synchronization reception request to the slave chip and receive a first positioning signal based on the first signal receiving module 111;

[0109] When the slave chip receives the synchronous reception request, it synchronously receives the second positioning signal with the master chip based on the second signal receiving module 121. The first positioning signal and the second positioning signal are signals of different frequencies.

[0110] The main chip 110 is also used to perform dual-frequency positioning calculation based on the first positioning signal and the second positioning signal to obtain a dual-frequency positioning signal.

[0111] The main chip 110 also includes a first communication module 114 and a first microprocessor module 115.

[0112] The first communication module 114 is used for the master chip to send a synchronization request signal to the slave chip to synchronize the master chip and the slave chip.

[0113] The first microprocessor module 115 is used to calculate the first positioning signal to obtain the first coordinate signal, and to obtain the second coordinate signal calculated by the slave chip based on the second positioning signal, and to perform dual-frequency calculation based on the first coordinate signal and the second coordinate signal to obtain the dual-frequency positioning signal.

[0114] The slave chip includes a second communication module 123 and a second microprocessor module 124.
