detailed description

In the following description, numerous technical details are set forth in order to provide the reader with a better understanding of the present application. However, those skilled in the art can understand that the technical solutions claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

It should be noted that, in the respective embodiments of the present invention, several concepts such as a "transfer box", a "logistics", a "box", and a "box unit" are equivalent.

For the tote for transporting liquid substances, when the turnover boxes are stacked in large numbers, because the liquid absorbs the wireless signals, some of the turnover boxes cannot effectively transmit the wireless signals.

One solution is to increase the power of the wireless communication module in the tote, although it can alleviate the original problem, but it will bring two new problems.

One problem is that because the battery is used as the power source in the turnover box, the energy consumption of the high-power wireless communication module will be greatly increased, thereby greatly reducing the standby time of the battery, and it is impossible to change the battery for many years. A lot of maintenance work.

Another problem is that the high-power wireless communication module is bound to have electromagnetic interference problems, which will affect other surrounding wireless signals, which does not meet the standards of relevant regulations.

There is a technical contradiction here. In order to counteract the absorption of liquid in the tote, it is necessary to increase the power of the wireless communication module, but in order to prevent the battery from being exchanged for many years and not to interfere with other communication, the power of the wireless communication module cannot be added. Big.

This application solves this technical contradiction with a creative solution. Part of the point is that position detection devices are respectively provided at the top and bottom of the logistics equipment (such as the totes) for detecting whether there are other appliances at the top or bottom. For example, a switching device can be used to force the switching device to be connected or disconnected by the pressure on the corresponding structure of the logistics device; a transmission interface is provided at the top and bottom of the logistics device, and can be transmitted when the two devices are stacked one on top of the other The interface is electrically connected; when a plurality of logistics appliances are stacked together, each of the logistics appliances knows its relative position through the top and bottom position state detecting devices, for example, the state of the position detecting device at the bottom of the lowest logistics device is not Other logistics appliances are detected (for example, the switching device is in an open state), and the state of the position detecting device at the top thereof is to detect other logistics devices (for example, the switching device is in an off state); the lowermost logistics device is periodically passed through and above. The transport interface connected to the logistics appliance wakes up above its sleep Logistics equipment (in order to save electricity, logistics equipment is generally in a dormant state until it is awakened by time or wake up through the transmission interface), and the information of the logistics equipment is transmitted, and the logistics equipment above it is awakened to receive the information transmitted by the logistics equipment below and Caching the received information; the upper logistics appliance then wakes up the logistics appliance above it through the transmission interface, and transmits its own information and cached information; thus starting from the lowest logistics appliance, waking up and uploading information through the transmission interface layer, and finally The information of the plurality of logistics appliances stacked together is summarized to the top level logistics appliance; the top logistics appliance transmits itself to the cloud server together with the information of all the logistics appliances stacked underneath. The information transmission between various logistics appliances can use low-power short-distance communication systems (such as Bluetooth, Zigbee, etc.), while the top-level logistics equipment and cloud server transmission can use high-power long-distance communication systems (such as 3G, 4G, 5G, etc.). Because the top-level logistics equipment is least affected by the loaded liquid material, the effect of transmitting information to the cloud server is best. In addition, preferably, a solar cell can be installed on the top of the logistics device, and the electric energy can be stored in the form of a capacitor or a rechargeable battery, which is specially used for a high-power long-distance communication system, and the low-power short-distance communication system uses an independent method. The built-in battery allows the built-in battery to be used for many years, greatly reducing the cost of maintenance. The top-level logistics appliance does not need to transmit the information to the cloud server immediately after receiving the information of the following logistics appliances, and can wait until the solar battery is charged or the rechargeable battery reaches a certain threshold before transmitting.

The specific embodiments of the present application are described in detail below.

The logistics tools mentioned in the various embodiments of the present application include, but are not limited to, the following types, folding card box, oblique insertion type logistics box, collapsible liquid tonnage box, reverse nesting box, folding wall box, small folding box , small logistics box, non-folding card box, medium-sized bulk box, cold chain logistics box, pallet box, stackable logistics turnover box, hoop box, parts box, tray, chassis car, with ring and so on.
