BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 A structural block diagram of a trailer positioning terminal provided by an embodiment of the present invention;

[0032] Figure 2 A flowchart of a trailer positioning method provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] Research shows that an important reason for the low dispatching efficiency of tractors and trailers in drop-and-hook transport is that the trailer is not equipped with a location information acquisition device, which makes it impossible for staff to obtain the current location information of the trailer in a timely manner, and it is even more impossible to achieve effective dispatching of tractors and trailers based on the current location information of the trailer.

[0035] In view of this, an embodiment of the present invention provides a trailer positioning terminal. Figure 1 This is a structural block diagram of a trailer positioning terminal provided by an embodiment of the present invention. Figure 1 The trailer positioning terminal includes a trailer body 1, a positioning module 2, a power supply module 3 and a position information sending module 4. The positioning module 2, the power supply module 3 and the position information sending module 4 are integrated on the trailer body 1; the position information sending module 4 is connected to the positioning module 2 to send out the current position information of the trailer; the power supply module 3 is connected to both the positioning module 2 and the position information sending module 4, and is used to supply power to the positioning module 2 and the position information sending module 4.

[0036] The above technical solution sets a positioning module 2, a power supply module 3 and a position information sending module 4 on the trailer body 1. The power supply module 3 can be used to power the positioning module 2 and the position information sending module 4, so that the positioning module 2 can collect the current position information of the trailer. The position information sending module 4 can send the current position information of the trailer collected by the positioning module 2 to the staff's monitoring terminal (such as a remote data control center or a mobile phone, etc.). In this way, the staff can obtain the current position information of the trailer in time based on the monitoring terminal, realize long-term continuous positioning and data communication of the trailer, which is used to improve the scheduling efficiency of tractors and trailers and meet the cargo operation needs.

[0037] Furthermore, the power supply module 3 includes a solar cell, a width light (also called a clearance light) and a brake light; the solar cell, the width light (clearance light) and the brake light are arranged on the outer wall of the trailer body, and are connected to the positioning module 2 and the position information sending module 4, and are used to supply power to the positioning module 2 and the position information sending module 4. When the trailer is attached to the tractor and is driving during the day, the positioning module 2 and the position information sending module 4 can rely on the brake light and / or the solar cell for power. When the trailer is attached to the tractor and is driving at night, the positioning module 2 and the position information sending module 4 can rely on the width light (also called clearance light) and / or the brake light for power. When the trailer is separated from the tractor, the positioning module 2 and the position information sending module 4 can rely on the solar cell for power. In this way, it is possible to obtain the current position information of the trailer when the trailer is in various situations, realize long-term continuous positioning and data communication of the trailer, improve the dispatching efficiency of the tractor and the trailer, and meet the cargo operation requirements.

[0038] In practice, when the trailer is driven by the tractor connected to it, the driver will step on the brake according to the road conditions. Only when the driver steps on the brake will the brake light light up, that is, the brake light will have electricity. Studies have shown that during the entire driving process, the driver will only step on the brake for 5%-10% of the time, which makes the time for relying on the brake light to power the positioning module 2 and the position information sending module 4 limited. Similarly, the width lamp (also called the clearance lamp) is usually turned on only at night. However, solar cells are easily damaged, and due to the limitation of the installation position in actual use, the photoelectric conversion rate of solar cells is low, which also makes the time for relying on the width lamp (also called the clearance lamp) or solar cell to power the positioning module 2 and the position information sending module 4 limited. Therefore, optionally, the power supply module 3 also includes a battery; the solar cell, the width lamp (also called the clearance lamp) and the brake light are all connected to the battery for charging the battery; the battery is also connected to the positioning module 2 and the position information sending module 4 for powering the positioning module 2 and the position information sending module 4. This arrangement can ensure that the positioning module 2 and the position information sending module 4 can be stably powered under any circumstances.

[0039] On the basis of the above technical solution, optionally, due to the different power supply capabilities of solar cells, width lights (also called clearance lights) and brake lights, the trailer positioning terminal also includes a charging current adjustment module; the charging current adjustment module is connected to the battery and is used to adjust the charging current value of the battery according to the element currently charging the battery; the element currently charging the battery includes at least one of solar cells, width lights (also called clearance lights) and brake lights. The essence of this arrangement is that when using at least one of solar cells, width lights (also called clearance lights) and brake lights to charge the battery, it is further ensured that each element currently charging the battery can charge the battery in the most efficient state, thereby improving the charging efficiency of the battery.

[0040] Exemplarily, the charging current adjustment module is a high-current fast charging IC.

[0041] Furthermore, the trailer positioning terminal may also include a power supply sequence adjustment module; the power supply sequence adjustment module is connected to the solar cell, the width light (also called the clearance light), the brake light and the storage battery, and is used to determine the element currently supplying power to the positioning module 2 and the position information sending module 4 among the solar cell, the width light (also called the clearance light), the brake light and the storage battery according to the current working state of the solar cell, the working state of the width light (also called the clearance light) and the working state of the brake light. This arrangement can improve the utilization efficiency of energy.

[0042] On the basis of the above-mentioned technical solutions, the trailer positioning terminal can optionally be configured to include a control module; the control module is connected to the positioning module 2, and is used to detect the current trailer motion state, and then adjust the time interval between two adjacent positioning information collections by the positioning module 2 and the time interval for data communication based on the current trailer motion state. For example, if the trailer is in a long-term parked state, the time interval between two adjacent positioning information collections by the positioning module 2 is set to t1; if the trailer is in a driving state, the time interval between two adjacent positioning information collections by the positioning module 2 is set to t2, t1>t2. Since the trailer is in a long-term parked state, the location information collected by the positioning module 2 remains unchanged. Such a setting can optimize the working mechanism of the trailer positioning terminal and reduce the energy consumption of the trailer positioning terminal, so that when the trailer is parked for a long time, the power consumption is almost zero, which can meet the demand for long-term standby.

[0043] In actual settings, there are many specific settings for the control module. Optionally, the control module includes a motion state acquisition unit and a positioning module control unit; the motion state acquisition unit is used to acquire the current trailer motion state; the positioning module control unit is connected to the motion state acquisition unit and the positioning module, and is used to control the opening time of the positioning module according to the current trailer motion state, thereby adjusting the time interval between two adjacent positioning information acquisitions by the positioning module, and adjusting the time interval for data communication at the same time. The essence of such a setting is to adjust the time interval between two adjacent positioning information acquisitions by the positioning module 2 and the time interval for data communication by controlling the opening time of the positioning module, and such a setting is easy to implement.

[0044] Furthermore, there are many ways to set the trailer motion state acquisition unit. For example, the trailer motion state acquisition unit can be set as an acceleration sensor, a vibration detection sensor, etc. This application does not limit this.

[0045] Since the trailer is parked for a long time, the position information of the trailer collected by the positioning module 2 twice in a row remains unchanged, or the acceleration is zero, or no vibration is detected. If the trailer is in a driving state, the position information of the trailer collected by the positioning module 2 twice in a row will change or the acceleration or vibration state will change. Optionally, the motion state acquisition unit is used to detect the motion acceleration, vibration or the position information of the trailer collected by the positioning module twice in a row to obtain the current motion state of the trailer. Among them, if the motion state acquisition unit detects the position information of the trailer collected by the positioning module twice in a row, this solution does not require the addition of other sensors in the trailer positioning terminal, which can reduce the production cost of the trailer positioning terminal.

[0046] In the above technical solution, optionally, there are multiple specific configuration schemes for the positioning module 2. Optionally, the positioning module 2 includes at least one of a positioning unit based on GPS positioning technology and a positioning unit based on Beidou positioning technology.

[0047] In the above technical scheme, optionally, there are multiple specific setting schemes for the location information sending module 4. Optionally, the location information sending module 4 includes at least one of a wireless communication module based on GPRS / 3G / 4G technology, a wireless communication module based on Bluetooth technology and a wireless communication module based on 433M.

[0048] Based on the same inventive concept, the present invention further provides a trailer positioning method, which is applicable to any one of the trailer positioning terminals provided in the embodiments of the present invention.

[0049] S301, the positioning module obtains the current position information of the trailer;

[0050] S302: The position information sending module sends the current position information of the trailer obtained by the positioning module.

[0051] Since the above trailer positioning method is applicable to any trailer positioning terminal provided in the embodiments of the present invention, it has the same or corresponding beneficial effects as the trailer positioning terminal to which it is applicable, and will not be described in detail here.
