TECHNICAL FIELD

[0001] The utility model relates to positioning navigation technical field, specifically, and relates to a mobile object positioning and sensing system. BACKGROUND

[0002] Traditional GPRS, Beidou positioning system and the like technology has the problem of low recognition accuracy caused by signal affected by environment in intelligent recognition, positioning, tracking, monitoring and management of mobile objects such as vehicles.

[0003] The application number is "202211091312.9", a kind of calibration method, equipment and system of road side sensor based on high-precision map, it provides accurate GPS longitude and latitude and the like absolute position information of target object on road by automatic calibration of target object through road test sensor on both sides of road.But the system needs to set equipment separately in road test, and it is easy to understand that when there is no power supply or sudden situation such as natural disaster on both sides of road in daytime, the system equipment cannot realize the function of auxiliary positioning of mobile objects on road. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the deficiency of prior art, and provides a positioning navigation system with higher adaptability.

[0005] To achieve the above object, the utility model provides a mobile object positioning and sensing system, which comprises a lamp and a platform system, the lamp comprises an LED light source, a driver, a battery module, a communication module and a sensing module for sensing and positioning mobile objects, an external power module is connected with the LED light source, the battery module, the communication module and the sensing module through the driver respectively.

[0006] The power module is used for power supply for other modules.

[0007] Preferably, when in light period and peak power period, the battery module supplies power for the LED light source, the communication module and the sensing module; when in light period and valley power period, the power module supplies power for the LED light source, the communication module and the sensing module.

[0008] Preferably, when the power module is powered off, the battery module supplies power for the communication module and the sensing module to ensure 24-hour operation of the sensing module.

[0009] Preferably, the sensing module is a zigbee host, and the current mobile object is provided with a zigbee terminal.

[0010] Preferably, the sensing module is a Bluetooth host, and the current mobile object is provided with a Bluetooth terminal.

[0011] Preferably, the photovoltaic module is connected to the battery for powering the battery.

[0012] Preferably, the number of the lamps is multiple, and the multiple lamps are arranged along the road direction at intervals, and each lamp performs sensing and positioning on the moving object when the moving object passes through the multiple lamps in sequence.

[0013] Preferably, the moving object is sensed and positioned by at least three lamps, so that the accurate coordinates of the moving object are obtained to assist the moving object to achieve high-precision positioning.

[0014] Compared with the prior art, the technical scheme has the following beneficial effects: the lamps are naturally distributed along the road (the equipment is shared, and the points are uniformly distributed), and since the lamps are fixed in position, the sensing and positioning of the moving object can be realized by sensing the position information through the sensing module under the condition that the latitude and longitude point information of the lamps is known, the automatic identification, positioning and management of the moving object can be completed all day long, non-contact and without stopping, and the anti-interference ability is strong and not easily affected by signals.

[0015] Further, the battery is arranged, the LED light source is powered by the battery during the peak power period, the function of peak load shifting is realized, the battery can also power the sensing module, and the sensing module can be powered in an emergency such as a power outage during the day or a natural disaster, so that one thing has three uses. The communication module can upload or receive the instructions and information of the LED light source while uploading the sensing information of the sensing module, so that one thing has two uses. The driver, the battery and the communication module are components used for controlling the LED light source or powering the LED light source, and the system only needs to add the sensing module without adding other components, so that the cost is lower (the hardware is shared, and works for 24 hours in an emergency mode).

[0016] In the moving object sensing and positioning system, the number of the lamps is multiple, and the multiple lamps are arranged along the road direction at intervals, and each lamp performs sensing and positioning on the moving object when the moving object passes through the multiple lamps in sequence, since the latitude point information of each lamp is fixed and known, the movement track of the moving object can be confirmed. Long-distance navigation of the moving object can also be realized. In addition, since the distance between the connected lamps is known, the speed of the moving object can also be monitored according to the time difference of the adjacent lamps sensing the moving object.

[0017] In the moving object sensing and positioning system, the sensing module only needs to sense the information of the moving object, and the communication module only needs to transmit and receive the information, so that each module only needs to complete a single action, and the logic is more efficient.

[0018] Other features, objects, and advantages of the present application will become more apparent from the following detailed description of non-limiting embodiments thereof as taken in conjunction with the accompanying drawings:

[0019] Figure 1 The system composition schematic diagram of the present application is shown in the figure. DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described and discussed with reference to the accompanying drawings of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, and all the other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative work fall within the protection scope of the present application.

[0021] It should be noted that when a component is referred to as being "fixed" to another component, it can be directly on the other component or intervening components can also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components can also be present. When a component is referred to as being "disposed on" another component, it can be directly disposed on the other component or intervening components can also be present. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] Referring to Figure 1 The embodiment provides a mobile object sensing and positioning system, which comprises a lamp and a platform system. The lamp comprises an LED light source, a driver, a battery, a communication module and a sensing module for sensing and positioning a mobile object. The mains power is connected to the LED light source, the battery, the communication module and the sensing module through the driver.

[0024] When there is no mains power supply, the battery supplies power to the communication module and the sensing module to ensure 24-hour operation of the sensing module. Preferably, when in the light-on period and in the peak power period, the battery supplies power to the LED light source, the communication module and the sensing module. When in the light-on period and in the valley power period, the mains power supplies power to the LED light source, the communication module and the sensing module.

[0025] Specifically, in the present solution, the mobile object sensing and positioning system further comprises a zigbee terminal installed on the mobile object, and the sensing module is a zigbee host. When a mobile object carrying a zigbee terminal enters the sensing range of the host, the zigbee terminal will send a very small data packet to the zigbee host, and the zigbee host will report the data packet to the platform system through the communication module. According to the latitude and longitude point information of the lamp itself, the sensing and positioning of the mobile object is realized, and the zigbee terminal can set the heartbeat packet interval to realize the monitoring of speed, status and trajectory. At the same time, the zigbee host can choose to reply the latitude and longitude point information to the zigbee terminal to help the mobile object for auxiliary positioning.

[0026] Since the lamp itself is fixed in position, the sensing and positioning of the mobile object can be realized by sensing the position information through the sensing module under the condition that the latitude and longitude point information of the lamp is known. The automatic identification, positioning and management of the mobile object can be completed all-weather, non-contact and without stopping. The anti-interference ability is strong and not easy to be affected by signals.

[0027] At the same time, since the lamp itself is equipped with a battery, even if it is in the daytime when the power supply is not supplied, or the power supply is disconnected due to an emergency, the positioning and identification management of the mobile object can be continuously realized through the battery power supply, and the mobile object can be assisted for positioning and navigation

[0028] The zigbee monitoring range is larger, the expandability is stronger, the cost is extremely low, there is no equipment cost, no construction cost, and no department coordination cost. The single packet data is extremely small, and the data volume is small. The data volume of traditional visual sensing equipment is large, and it depends on network facilities and high bandwidth. For example, using visual sensors for monitoring and positioning will have a very large data processing, high equipment cost and low efficiency.

[0029] Of course, although the sensing module in the present solution uses a zigbee host, it can also be a Bluetooth host, and the mobile object is equipped with a Bluetooth terminal.

[0030] And at the same time, the communication module can also upload or accept the instructions and information of the LED light source when uploading the sensing information of the sensing module. The driver and the communication module both play a dual role.

[0031] And more preferably, the number of lamps in the mobile object sensing and positioning system is multiple, and the multiple lamps are arranged along the road direction at intervals. When the mobile object passes through the multiple lamps in turn, each lamp senses and positions the mobile object. Since the latitude point information of each lamp is fixed and known, the movement trajectory of the mobile object can be confirmed, and the positioning and movement trajectory of the mobile object can be recorded and stored through the system platform for ready use at any time. At the same time, long-distance navigation of the mobile object can also be realized.

[0032] In addition, since the distance between the connected lamps is known, the speed of the moving object can also be monitored according to the time difference of the adjacent lamps sensing the moving object. And since the number of lamps is multiple, if one of them is damaged or not measured accidentally, other lamps can still locate the moving object, and the situation that the entire section cannot be located will not occur.

[0033] At the same time, since the number of lamps in the moving object sensing and positioning system is multiple, the moving object can be sensed and positioned on at least three lamps, that is, the accurate coordinates of the moving object can be obtained, the moving object can be assisted to realize high-precision positioning, and the problems of low positioning accuracy and weak or even interrupted satellite signals in some specific environments can be solved.

[0034] The moving object sensing and positioning system further comprises a photovoltaic module connected with the battery for supplying power to the battery.

[0035] The specific embodiments of the utility model are described above. It should be understood that the utility model is not limited to the above specific embodiments, and one or more of the above embodiments can be combined. Those skilled in the art can make various changes or modifications or combinations within the scope of the claims, which does not affect the essential content of the utility model. In the case of no conflict, the embodiments of the application and the features in the embodiments can be combined arbitrarily.
