Description
Technical field
The present invention relates to ocean navigation, navigation field, especially relate to a kind of method and system that can show boats and ships Future Positions tidal height.
Background technology
In shipping, some water channel and bay could must be navigated by water and entering and leaving port before and after climax; At military aspect, sometimes in order to select favourable debarkation point and time, just must consider and grasp the situation of tide; In production, coastal fishery, culture fishery, agricultural, salt industry, development of resources, port engineering construction, measurement, environmental protection and tidal power generation etc., all rules of GPRS tidal fluctuations.
Existing tide inquiry is generally based on tide-prediction table (referred to as tidal table), according to longitude and latitude and the temporal information of position, inquires about corresponding tidal height.Comparatively advanced mode is input in the smart machines such as computing machine by tide-prediction table, then the position that will inquire about and time is inputted, directly transfer corresponding tidal height change numerical value by computing machine to show, or the form of corresponding numerical value by curve map is showed more intuitively.As in the tidal table query page (http://app.cnss.com.cn/tide_search.php) of maritime net, harbour and the query time of inquiry can be selected, and obtain the tidal height change curve at corresponding this harbour of date.This mode can meet the demand of harbour service, but for the boats and ships that position constantly changes, just cannot obtain the tidal height change information in the region that boats and ships will reach, be unfavorable for sea faring development.
Summary of the invention
The present invention mainly solves the technical matters that can only obtain the tidal height of fixed location existing for prior art, provide a kind of can obtain the region that boats and ships will arrive tidal height numerical value, the boats and ships tide display method predicting Tidal Information dynamically, is accurately provided for navigating.
The present invention is directed to that above-mentioned technical matters mainly solved by following technical proposals: a kind of boats and ships tide display method, comprises the following steps:
A, the longitude J reading the current present position of boats and ships from GPS module, latitude W and time T

As preferably, described t is more than or equal to 10 minutes and is less than or equal to 3 hours.
As preferably, described n is less than or equal to 100.The size of t and n can set as required, and suitable numerical value can save computational resource when providing enough information, namely reduces hardware requirement, controls cost, and reduces the response time.
Need in this programme in electronic chart, to set navigation route in advance, compared to last scheme, staff can be made to understand the change of tidal height on course line better, meet the demand in scheduled airline situation.
Aforesaid two schemes, all need setting refresh interval (as 1 minute), repeat once whole step every a refresh interval, make the curve map of display change along with course line change or vessel orientation and constantly to change, and the data shown are revised.
A kind of boats and ships tide display system, comprise GPS module, navigational speed measuring instrument, electronic compass and CPU module, described GPS module, navigational speed measuring instrument are connected with central processing unit respectively with electronic compass, described central processing unit runs electronic chart software, and described central processing unit is also connected with the storer storing tidal table.
As preferably, described central processing unit is also connected with wireless communication unit, described central processing unit by wireless communication unit be arranged on land tide querying server and be connected.
As preferably, described central processing unit is also connected with echo sounder, described central processing unit is by current vessel position information, temporal information and be sea water advancedly sent to tide querying server by wireless communication unit, and described vessel position information comprises altitude information.
Native system is applicable to aforesaid two kinds of query and indication methods.GPS module is used for providing current location information, and navigational speed measuring instrument is used for providing velocity information, and electronic compass is used for providing directional information, and central processing unit is used for carrying out controlling and calculating.In native system, tidal table in storer compares conventional tidal table specifically, conventional tidal table can only provide the Tidal Information at each harbour, and this programme is it is desirable that the Tidal Information on whole sea, the tidal table used is more perfect, data volume is very huge, is obviously irrealizable by artificial enquiry.Because the memory capacity of storer is limited, also be not suitable for Global Sea-level tidal fluctuations data to be all stored into storer from inquiry velocity, so the tidal data of the conventional navigation area of these boats and ships only can be stored in memory, and when ship's navigation is not to when storing the region of data, by wireless communication unit from being arranged on the data of inquiring about needs the comparatively complete tide querying server of land, information.
The tidal data related to due to this programme is not limited to harbour information, namely for the requirement of tidal table (tidal data storehouse) far above the tidal table of routine, this has only been difficult to all Data Collections by detection means in the past.The height at the echo sounder end off sea can be found out by the echo sounder be arranged on boats and ships, the sea level height of boats and ships present position is calculated again according to the distance (this distance be definite value, can input by staff is manual or is recorded by senser element) on instrument and sea.The sea level elevation of GPS module present position can be recorded by GPS module, the sea level elevation of boats and ships present position is calculated according to the difference in height on GPS module and sea (difference in height is similarly definite value, by the manual input of staff or can be recorded by senser element).By wireless communication unit, the data such as sea level height, sea level elevation, temporal information, latitude and longitude information are sent to tide querying server, tide querying server calculates the difference of sea level height and superelevation reference field, is tidal height.Also can be drawn the altitude information on sea by sea level elevation and the data be stored in tide querying server, thus calculate the tidal height of now this position, two tidal height are used for mutually revising, and obtain information accurately.Constantly above-mentioned information is sent to tide querying server by boats and ships, tide querying server, by real-time tidal height, uses tide prediction algorithm constantly to carry out improving and revising to the numerical value in tidal data storehouse, obtains result more accurately.Boats and ships tide display system can download revised tidal data by wireless communication unit, upgrades the data in storer, keeps the accuracy of the marigram figure of prediction.
The substantial effect that the present invention brings is, can show boats and ships will the tidal data of in-position, and provide dynamic curve map, the boats and ships constantly changed for position provide Tidal Information accurately; Constantly can revise tidal table, form complete tidal data storehouse, instead of be only limitted to limited several harbours.
