The technical solution adopted by the present invention to solve the technical problems is:A kind of electric vehicle electric charging station intelligent electric Pond detection device, including several chargers, each charger charges to a battery, and the charger is by relay control No to charge to battery, each charger is configured with a wireless sensor network node.
Further include a control room, the wireless sensor network node that the control room is configured by each charger respectively with Each battery signal connection;The wireless sensor network node includes battery detecting module, CPU and wireless communication module, institute It states CPU to connect with control room signal by wireless communication module, the CPU controls the opening and closing of the contact of the relay, described Battery information is fed back to CPU by battery by battery detecting module.
Each wireless sensor network node further includes display module and alarm module, the display module and alarm module It is connect with cpu signal.
The wireless communication module is GPRS communication module.
The invention has the advantages that the electric vehicle electric charging station Intelligentized battery detection device of the present invention, integrates The modules such as battery detecting module, CPU module, display module, alarm module and wireless telecommunications, as wireless sensor network One node so that wireless sensor network node not only has the function of conventional gathered data, while is also provided with basis The data of front-end collection carry out the function of active process, form an intelligentized network node;It is distributed especially suitable for field Formula charging pile or charger can well achieve effective control charger in region.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the electric vehicle electric charging station Intelligentized battery detection device of the present invention.
Fig. 2 is wireless sensor network node in electric vehicle electric charging station Intelligentized battery detection device of the invention Structure diagram.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with Illustration illustrates the basic structure of the present invention, therefore it only shows composition related to the present invention.
As shown in Figure 1, a kind of electric vehicle electric charging station Intelligentized battery detection device of the present invention, fills including several Motor, each charger charge to a battery, and the charger controls whether to charge to battery by relay, each to charge Machine is configured with a wireless sensor network node.Further include a control room, the nothing that the control room is configured by each charger Line sensor network nodes are connect respectively with each battery signal.
As shown in Fig. 2, the wireless sensor network node includes battery detecting module, CPU, wireless communication module, shows Show module and alarm module, the CPU is connect by wireless communication module with control room signal, and the CPU controls the relay Battery information is fed back to CPU, the display module and alarm by the opening and closing of the contact of device, the battery by battery detecting module Module is connect with cpu signal.The wireless communication module is GPRS communication module.
The course of work of the present invention is as follows:
1st, each wireless sensor network node is communicated by GPRS and control room, when control room issues charging life It enables, wireless sensor network node receives charge command and stores, and charger and electricity are connected by charge command control relay Pond, charger charge the battery;If control room publication stop charge command, by wireless sensor network node control after Electric appliance disconnects the connection of charger and battery, stops charging.Arrangement of time and charging of the charge command including charging Threshold values, it is 7 to be arranged such as the charging time:00-8:30 and 9:00-10:00;Charge threshold is the 95% of battery SOC or is full of.
2nd, in battery charging process, wireless sensor network node obtains battery information in real time by battery detecting module (the predominantly state-of-charge SOC of charging voltage, charging current, temperature and battery), by wireless sensor network node Display device real-time display battery information, and control room is transmitted this information to by GPRS simultaneously and is monitored in real time.If inspection It measures there are one being more than defined value in temperature, charging current and charging voltage, then by the alarm of wireless sensor network node Module is alarmed, while relay is controlled to disconnect battery and charger, stops charging, and pass through GPRS to stop charging reasons It is sent to control room;If detecting the threshold values that battery charge state SOC is setting, relay is controlled to disconnect battery and charging Machine stops charging, while informs control room by GPRS.
The modules such as battery detecting module, CPU and wireless telecommunications are integrated into an intelligence of wireless sensor network by the present invention It can node.When battery detecting quantity increases and decreases, as long as increasing and decreasing the wireless sensor network node of identical quantity accordingly, The normal detection of other batteries is not influenced, and without updating SCM program, there is good extendibility.In addition, existing management It is mainly that the battery for concentrating charging is detected with control mode, is not suitable for the management of field charger, and the present invention then may be used To take into account the battery detecting of concentration charging and the charging of field distribution and Charge Management and control well.
