ocpp_simulator

Simulator of a Charge Point via OCPP protocol

SOAP is used via xml templates, so this gem do not depend on any soap stack ...

5 usages :

• client.rb : invoke CP->CS dialog. Alone can invoke a SOAP request to a scada
• server.rb : serve a CS->CP dialog, as CP. Alone it print request/responses, responses are always status=Accepted. server api : invoke a client callback foreach request received see tc.rb for simulate CS
• cp.rb : simulate one Charge Point with multiple connectorId, use client.rb and serveur.rb for scada dialogs, make some start/stop transactions, some notifications.
• tc.rb : client as scada: send commandes to chargePoints
• parc_sim.rb : simulate a set of charge point.

Some tools developped with the framework:

• hmi_test.rb : simple HMI for simulate a charge point in plaforme : test central ocpp configuration
• tc_batch.rb : loop with some centrale commands for stimulate charge point
• rcrelai.rb : ocpp cs->cp router : receive commands on listen socket and route as client to another IP:port addresse From/To/MessageId are updated, timing is calculate News ====

• dataTransfert in hmi_test
• support https for soap-client

CP : simulation of a ChargePoint

Usage: > ruby cp.rb name ip port path url_server c1 c2 c3... > ruby cp.rb SIEM001 localhost 6061 /ocpp http://localhost:9090/ocpp 1 2 3 4

What is simulate:

• boot, lock , ask autorize, start charge, stop charge : autonomous (tempo/random/duration)
• energies imported, send it by meterValues periodicly
• start / stop charge by remote commande (suppose that (transactionId%100) => connectorId !!)
• change Availlibility by remote commande (Inoperative ==> reboot)

What is missing:

• statusNotification with errorCode
• diagnostic, dataTransfered,updateFirmware (!), getConfiguration,reset,
• localList of tag (the tag is alays the same : '12345678')
• reservation

Parc_sim

Create a bunch of ChargePoint

   > ruby parc_sim.rb  nbChargePoint  ip  port0 path  url_server  nb_connector_by_cp
   > ruby parc.rb  10 localhost 6060 /ocpp   http://localhost:9090/ocpp  1 2 3 4

This will create :

• 10 chargePoints, 4 connector on each,
• first ChargePoint will use port 6060, seconde 6061 .. and so on
• all cp will send data to asoap server a locolhost:9090/ocpp

Configuration

All Soap requests/responses are configured in templateOCPP.rb

Client : each SOAP request/response are configured with

• request: xml template to send, each 'value' place are represented with a key
• request: list the key in request (replace strings) to be use a parameters
• response : list of filter of value to extract from request

Server : each SOAP request/response are configured with

• request: hash of 'xpath' to be use for extract data, value of hash are varnames. So a request received is represented by a hash of varname=>value
• response : (as request of client) : string template, list of key

LIMITATION !!! : all that SOAP stuff work only with xml with statics structure !

• you can't extract a list of tagid received from CS
• you can't send a free list of measures
