[0020] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] In order to solve the problems existing in the prior art, the embodiments of the present invention provide a speed measurement and positioning method, device, electronic device and storage medium.

[0022] The embodiment of the present invention provides a speed measurement and positioning method, the process of which is as follows: Figure 1 As shown, the following steps are included:

[0023] Step S1: When the rack train is running on the rack rail, a tooth number recognition sensor is used to continuously measure the number of teeth on the rack rail, and the running time of the rack train passing a preset distance is calculated, wherein the tooth number recognition sensor is arranged on the rack train.

[0024] The preset spacing may be the spacing between two adjacent teeth or the spacing between two non-adjacent teeth; the travel time of the rack train passing the preset spacing is calculated by the tooth number recognition sensor using the tooth number recognition time of the rack.

[0025] Specifically, when the rack train is traveling on the rack, the number of teeth of the rack is continuously identified using a tooth number identification sensor, and the travel time can be obtained by calculating the difference in corresponding time according to the time of each tooth number identification data update.

[0026] Exemplarily, the preset pitch is a single pitch, the recognition time of the number of teeth N is t1, the recognition time of the number of teeth N-1 is t2, and the driving time is the difference between t1 and t2.

[0027] Step S2: Determine the real-time speed of the rack railway train according to the travel time and the preset distance.

[0028] The above method of this embodiment further includes the following steps:

[0029] When the rack train is running on the rack rail, the number of teeth of the rack rail is continuously measured by a tooth number identification sensor to determine the real-time position of the rack train.

[0030] Specifically, the real-time position of the rack train may be the number of teeth of the rack, or may be the distance between the rack train and the starting point or the end point of the rack.

[0031] The above method of this embodiment further includes the following steps:

[0032] When the rack train passes over the check rail, the check sensor on the rack train is used to identify the coding information of the check rail, wherein the check rails are arranged at intervals along the extension direction of the rack; the absolute position of the rack train is determined according to the coding information.

[0033] Specifically, Figure 2 As shown, the rack rail is arranged between the tracks, and the check rail is arranged between the rack rail and the track. When the rack rail train restarts on the rack rail, the train cannot determine the real-time position of the train due to power failure. The check sensor located on the rack rail train can identify the coding information of the check rail, and determine the absolute position of the rack rail train according to the coding information.

[0034] Preferably, the absolute position information includes the number of teeth of the check rail corresponding to the rack rail and / or the distance value between the check rail and the starting point of the rack rail.

[0035] For example, Figure 3 As shown, the check rail includes two sets of coded information, which correspond to the number of teeth and the tooth spacing. One set of coded information is the number of teeth of the check rail corresponding to the rack rail, and the other set of coded information is the distance value between the check rail and the starting point of the rack rail.

[0036] The above method of this embodiment further includes the following steps:

[0037] If the absolute position of the rack train is the starting point of the rack, an intervention instruction is generated and sent to the gear engagement mechanism, so that the driving gear of the rack train is meshed with the rack.

[0038] The rack-rail transition equipment is a track supporting structure that enables the driving gear to effectively mesh with the rack rail when the rack-rail vehicle enters the rack-rail section from the adhesion section.

[0039] Specifically, one set of check rails is set at the starting point of the rack rail. When the rack rail train passes through the check rail, it can be determined that the rack rail train is about to enter the rack rail section, and an intervention instruction is generated and sent to the gear entry mechanism, so that the driving gear of the rack rail train engages with the rack rail.

[0040] The above method of this embodiment further includes the following steps:

[0041] When the rack train passes over the check rail, the first probe and the second probe of the check sensor are used to respectively identify the coded information of the check rail, wherein the first probe and the second probe are arranged front and back along the length direction of the rack train; the travel direction of the rack train is determined according to the time when the first probe and the second probe identify the coded information.

[0042] Among them, the first probe and the second probe can both individually identify the coding information of the verification rail. Since the first probe and the second probe are arranged front and back along the length direction of the rack railway train, there is a difference in the time for the first probe and the second probe to identify the coding information.

[0043] Specifically, when the time when the first probe recognizes the coding information is before the time when the first probe recognizes the coding information, it is determined that the rack train is traveling in the forward direction; when the time when the first probe recognizes the coding information is after the time when the first probe recognizes the coding information, it is determined that the rack train is traveling in the reverse direction.

[0044] The above method of this embodiment further includes the following steps:

[0045] Determining the recognition state of the verification sensor according to the real-time speed of the rack train and the length of the verification rail;

[0046] When the identification state is a completed state, the absolute position of the rack railway train is determined according to the coded information.

[0047] The length of the check rail is a fixed value, and whether the check sensor can completely identify the check rail can be determined according to the real-time speed of the rack rail train and the length of the check rail.

[0048] Specifically, when the recognition state is a completed state, the absolute position of the rack rail train is determined according to the coding information; when the recognition state is an uncompleted state, the check rail continues to be recognized to obtain complete coding information, so as to avoid incomplete recognition of coding information, resulting in erroneous recognition results.

[0049] The above method of this embodiment uses a tooth number recognition sensor to continuously measure the number of teeth of the rack rail when the rack rail train is running on the rack rail, and calculates the travel time of the rack rail train to pass a preset distance; based on the travel time and the preset distance, the real-time speed of the rack rail train is determined, which can efficiently and accurately complete the speed measurement of the rack rail train and solve the problem of low speed measurement accuracy of the rack rail train.

[0052] a tooth number measurement module, used for continuously measuring the number of teeth of the rack rail using a tooth number recognition sensor when the rack rail train is traveling on the rack rail, and calculating the travel time of the rack rail train passing a preset distance, wherein the tooth number recognition sensor is arranged on the rack rail train;

[0053] The speed measuring module is used to determine the real-time speed of the rack railway train according to the travel time and the preset distance.

[0054] Regarding the speed measuring and positioning device for a rack railway train in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated on here.
