  • the control devices 333 and 334 assigned to the management device 322 include: It is assumed that a second device Q that performs a settlement process according to the second method is provided. Since the type of the request is the settlement process using the first method, the transmission / reception device 31 is assigned to the control device 331 or 332 including the second device P that performs the settlement process according to the first method. Device 321 is selected.
  • Step 24 the management device 321 selects one control device from the plurality of control devices 331 and 332, and outputs the data input from the transmission / reception device 31 and the type of the client device to the selected one control device. I do. Here, it is assumed that the control device 331 is selected.

  • the first device A is a first device that controls a POS terminal
  • the first device B is a first device that controls a ticket gate at a station. Since the type of the client device is information indicating the POS terminal, the control device 331 selects the first device A that controls the POS terminal.
  • the second device P included in the control device 331 processes the data input from the management device 321. Since the data input from the management device 321 is the price information of the product (1,000 yen), the second device P uses the user device 11 that performs short-range wireless communication with the client device 21 according to the first method. It is assumed that a process for reducing the electronic money balance prescribed by the first method by 1,000 yen is executed. Thereafter, the second device P outputs to the first device A information indicating payment completion (or payment success) or information indicating payment incomplete (or payment failure) according to the execution result. Here, it is assumed that information indicating completion of payment is output from the second device P to the first device A.
  • Step 27 the selected one first device A outputs a control signal of the client device based on the result of the processing in the second device P. That is, when information indicating the completion of payment is output from the second device P, a control signal instructing output of a sound or display indicating the completion of payment is output, and when information indicating completion of payment is output, And outputs a control signal for instructing output such as a sound or display indicating that payment has not been completed.

  • Step28 the client device receives the control signal and executes it. Since the control signal output from the first device A is a signal for outputting a sound indicating completion of settlement and for instructing the blinking of the LED, the client device outputs a sound indicating completion of settlement by executing the control signal. Blink the LED.

Abstract

Afin de permettre un raccourcissement du temps de développement et de dévier des actifs déjà existants, ce dispositif serveur est connecté à de multiples dispositifs clients sur un réseau et est pourvu d'un dispositif de gestion et de multiples dispositifs de commande qui comprennent de multiples premiers dispositifs et de multiples seconds dispositifs. Le dispositif de gestion sélectionne un dispositif de commande parmi les multiples dispositifs de commande, et délivre, au dispositif de commande sélectionné, des données entrées à partir d'un dispositif d'émission/réception, un type de demande et un type de dispositif client. Le dispositif de commande sélectionné sélectionne un premier dispositif parmi les multiples premiers dispositifs sur la base du type du dispositif client entré depuis le dispositif de gestion, le premier dispositif sélectionné sélectionne un second dispositif parmi de multiples seconds dispositifs sur la base du type de demande entré depuis le dispositif de gestion et délivre un signal de commande du dispositif client sur la base des résultats de traitement dans le second dispositif, et le second dispositif sélectionné traite les données entrées depuis le dispositif de gestion.
