Embodiment 1

[0072] Since billing nodes are energy-constrained devices, they usually need to be powered by batteries or charged by solar energy. Therefore, in order to prolong the usage time of the charging node and avoid failure due to insufficient power, the charging node enters the sleep state, that is, stops the circuits and components, when no user operates the charging node or the charging node has no session to process. part of the work in order to save energy. Meanwhile, in order to ensure normal communication of the wireless mesh network composed of charging nodes, all charging nodes (including the first charging node and the second charging node) need to perform synchronous sleep. There are many methods for realizing synchronous sleep. For example, a synchronous clock can be set, and the synchronous clock controls each charging node to enter the sleep state at the same time point and enter the active state at the same time.

Embodiment 2

[0090] This embodiment proposes a technical solution. In the technical solution, the delay ratio in the session processing process is Figure 4 The technical solution shown is shorter, especially in the delay-sensitive banking business, the shorter delay can avoid user operation failure, thereby bringing a better experience to the user.

[0091] In this embodiment, a state is added for the charging node, that is, a temporary active state. After the charging node enters the temporary active state, the charging node remains active all the time. Image 6 It is a state transition diagram of the charging node in the second embodiment of the present invention. like Image 6 As shown, in this embodiment, three states are set for the charging node, ie, an active state, a sleep state and a temporary active state. Wherein, the charging node can be figure 2 The shown first billing node may also be figure 2 The second charging node shown. The charging node transitions from the sle...

Abstract

The invention discloses a charging system, a charging node and a charging method. The charging system comprises a first charging node and a second charging node, wherein only the second charging node has a gateway function, the first charging node and the second charging node form a wireless mesh network, and the communication is conducted through the wireless mesh network, the second charging node is connected to a remote wireless communication network through a remote wireless communication link, the first charging node is used for transmitting a first conversation message to the second charging node through the wireless mesh network, and the second charging node is used for receiving the first conversation message through the wireless mesh network and transmitting a second conversation message to the first charging node through the wireless mesh network. In this way, one remote wireless communication link does not need to be arranged on each charging node, so that the communication expense required can be greatly reduced.

Description

technical field [0001] The invention relates to charging technology, in particular to a charging system, a charging node and a charging method. Background technique [0002] A parking meter is a device that charges vehicles parked in an area based on the time they have been parked. Usually, the parking meter needs to connect to some servers (such as the management center or bank settlement server) through the Internet, and by communicating with these servers, it performs status reporting, credit card operations, and so on. [0003] figure 1 It is a schematic structural diagram of an existing parking charging network. like figure 1 As shown, the parking charging network includes: a charging node 101 , a GPRS network 102 and a charging server 103 . Wherein, each charging node 101 communicates with the charging server 103 through the GPRS network. [0004] Depend on figure 1 It can be seen that, in the existing parking metering network, each parking meter needs to be conn...
