Description

Technical Field

[0001] The present invention relates to the technical field of speed display of a positioning system, and in particular to a speed display method, device and electronic equipment. Background Art

[0002] At present, the field of driving speed measurement generally uses hybrid positioning or selects a suitable, high-performance GPS receiver to improve the positioning accuracy, thereby improving the driving speed measurement accuracy.

[0003] Nowadays, there are two main solutions to improve the accuracy of driving speed measurement: The first solution is to use a hybrid positioning method. Specifically, it is a hybrid positioning technology that combines cellular networks with GPS. Cellular network positioning technology is a positioning technology based on mobile communication networks, which calculates location coordinates by measuring the transmission time difference of radio signals. Hybrid positioning technology usually uses cellular network positioning technology for rough positioning, and then uses GPS positioning technology for precise positioning. However, the disadvantage of the above solution is that it requires turning on both cellular network and GPS signal receivers at the same time when using it, so its power consumption is relatively large. At the same time, hybrid positioning technology requires the addition of a cellular network receiver, which increases the hardware cost. In addition, the positioning accuracy of the cellular network is relatively low.

[0004] The second solution is to choose a suitable, high-performance GPS receiver. The positioning accuracy of a GPS receiver is related to the receiver's receiving sensitivity and the number of receiver channels. The higher the receiving sensitivity of a GPS receiver, the more weak signals it can receive, reducing receiver errors and thus improving positioning accuracy. The more receiving channels a GPS receiver has, the more satellites it can receive at the same time. In an environment with many obstructions, it can ensure that a sufficient number of satellite signals are received, thereby improving positioning accuracy. However, the disadvantage of the above solution is that choosing a high-performance GPS receiver requires increasing the hardware cost of the GPS receiver.

[0005] In the field of ships, when the outboard motor is stationary, there is a lot of interference in the GPS speed value. If the original speed value is directly displayed on the main control display, there will be a speed value when the outboard motor is stationary. If the original speed value is filtered and the filtered speed value is directly displayed on the main control display, the filtering depth will be large due to the large interference, causing the filtered speed to lag significantly behind the original speed before filtering, which will cause the speed on the main control display to lag significantly behind the actual outboard motor speed.

[0024] See also Figure 1 , Figure 1 : is a flow chart of a method for displaying a moving speed provided in an embodiment of the present application. In an embodiment of the present application, the method includes: S101. Collecting an original signal, where the original signal is a speed signal sent by a positioning system.

[0025] The execution entity of this application can be a cloud server.

[0026] In one embodiment of the present application, during the ship's travel, the cloud server will continuously receive and store the original signal sent by the GPS receiver, that is, the ship's speed signal. However, the GPS receiver receives the unprocessed original speed signal, which may cause interference.

[0027] In one possible implementation, the method of the present application further includes: Pre-set different acquisition frequencies; Associating each of the acquisition frequencies with each of the motion states; The corresponding acquisition frequency is called based on the motion state.

[0028] In one embodiment of the present application, first, the collection frequencies of the first frequency and the second frequency can be pre-set in the cloud server to adapt to the ship in the stationary state and the running state, and the first frequency is less than the second frequency to reduce energy consumption, and then the first frequency is associated with the stationary state and the second frequency is associated with the running state. When the cloud server detects that the ship is in the stationary state, the collection frequency is set to the first frequency; when the cloud server detects that the ship is in the running state, the collection frequency is set to the second frequency.

[0029] S102, performing low-pass filtering on the original signal to obtain a filtered signal, wherein the filtered signal is a movement speed signal obtained after performing low-pass filtering on the original signal.

[0030] In one embodiment of the present application, the GPS receiver on the ship receives the raw signal without processing and performs low-pass filtering. The filter function is: , the filter cutoff frequency It is necessary to ensure that all interferences that occur when the ship is stationary are filtered out. The smaller the value, the greater the filter depth, the smoother the signal waveform after filtering, and the longer the lag time, that is, the worse the real-time tracking ability of the filtered signal and the original signal before filtering.

[0031] S103: Determine the motion state of the moving object according to the original signal and the filtered signal, where the motion state at least includes a stationary state and a running state.

[0032] In one embodiment of the present application, the current motion state of the ship can be determined by the received original signal and the filtered signal. Specifically, after obtaining the unprocessed original speed signal of the GPS, that is, the original signal, the low-pass filter filters the original speed signal. According to the obtained original speed signal and the corresponding filtered signal, the current motion state of the ship can be determined, and the motion state of the ship includes at least two states: a stationary state and a running state.

[0033] In one possible implementation manner, the determining of the motion state of the moving object according to the original signal and the filtered signal, wherein the motion state includes at least a stationary state and a running state, specifically includes: Acquire the original signal and the filtered signal; Determine whether the original signal and the filtered signal are equal to zero: If the original signal and the filtered signal are both equal to zero, the motion state is the static state; If both the original signal and the filtered signal are not equal to zero, the motion state is the running state.

[0034] In one embodiment of the present application, first, the original signal emitted by the GPS receiver, that is, the original speed signal, is obtained, and then the original speed signal is processed into a filtered signal through a low-pass filter. The unprocessed original speed signal of the GPS may be A, and the filtered signal after filtering may be B. The values ​​of A and B are judged, and the motion state of the ship is determined by the result of the judgment.

[0038] In one embodiment of the present application, it is assumed that the unprocessed current original signal is A i , the original signal stored in the cloud server is A i-1 , the current filtered signal is B i , set an error value in advance. Specifically, the error value can be used to determine whether the increased speed is the real speed or an interference signal. Since the speed increases gradually rather than suddenly, it can be used to determine whether the ship is still stationary. i ≠0, B i = 0, the ship may be in two states, static state or first state. At this time, it is necessary to judge A i With A i-1 Whether the difference between is within the error range is used to determine whether the ship is in a stationary state or the first state. When , because the A value suddenly changes, the A value is an interference signal, indicating that the ship is stationary; when , it indicates that the ship is in the first state, that is, it is just starting and the speed is gradually increasing.

[0040] In one embodiment of the present application, the movement of the ship also includes a second state. Specifically, the second state is between the running state and the static state. Before the ship changes from the running state to the static state, it will be in the second state, that is, it will be in the just-stopped state. The second state is determined by the original signal and the filtered signal.

[0043] S104: Acquire the motion state, and select a display value based on the motion state, where the display value includes the original signal or the filtered signal.

[0044] In one embodiment of the present application, a ship is generally provided with a display for displaying the speed and navigation status. The cloud server will obtain the motion status determined by the front-end step, and select a suitable display value according to the motion status to display on the display on the ship, so that the operator on the ship can know the motion status and speed of the ship more clearly.

[0045] In one possible implementation, obtaining the motion state and selecting a display value based on the motion state specifically includes: Acquiring the motion state; Determine whether the motion state is the static state: If the motion state is a stationary state, the displayed value is the filtered signal; If the motion state is not a static state, the displayed value is the original signal.

[0046] In one embodiment of the present application, the motion state obtained in the front-end step is first obtained, and the motion state of the ship can be roughly divided into two types, a stationary state and a non-stationary state. When the ship is in a stationary state, the displayed value is a filtered signal, that is, the speed after filtering; when the ship is in a non-stationary state, the displayed value is the original signal, that is, the speed before filtering.
