Technical field
The present invention relates to domestic network system, especially about control device in the domestic network system and method.
Background technology
Along with development of science and technology, the automatic control of family that closely reaches the remote control domestic electrical equipment product will enter family's step.The family at initial stage control automatically is to utilize phone or infrared ray to control each equipment respectively, fail mutually between each equipment to form and connect, but now the domestic network system between the household appliances of constructing by means of communication and the controller of control domestic network system carry out integrated management.
The simple structure chart of domestic network system as shown in Figure 1, a plurality of electronic products of family such as refrigerator, air-conditioning, microwave oven, washing machine, PC (PC) etc. connect by communication bus and constitute domestic network system.If the microcomputer computer of each product possesses the compatible communication function, directly connect and compose domestic network system with communication bus; If the microcomputer of each product does not possess the compatible communication function, the additional communication module of assembling constitutes domestic network system on each product.Can select to control the controller of the domestic network system of family, possess PC in present most of families, the application program of installation and control domestic network system in PC just can be used network controller by PC.
The control method in domestic network system of the family of prior art is described below with reference to Fig. 2:
Suppose by N product composition network, suppose to communicate mutually between product A and the product B.At first, the user utilizes product A to import the control command S21 of product B.That is, be example with the product A, observe control of product device (the Graphic User Interface) picture of display that is connected with PC or the electronic product that possesses display unit, again by input mediums such as keyboard, mouses, the order of input control product B.
Product A transmits the control command S22 of user's input to product B.Be the transmission (for example LAN/RS 232-C) of the control device control self of product A, or be connected to outside conveyer (for example modem dedicated for electric line communication), transmit after the control command of user's input is modulated into the order that is fit to communication line.Product B will be received the control command S23 that transmits from product A.Follow the action S24 that product B will be carried out the relevant controlling order.That is, the control device of product B will the algorithm of sequencing reads the control command bag when making after, finish relevant action.
Then, product B transmits the reply data S25 that has finished control command to product A.Product A is received the reply data S26 that product B transmits, learn that control command has normally been carried out after, will carry out next one and move; When A does not receive reply data within a certain period of time, will transmit control command once more or cut off communication.
Because after product B transmitted and to reply, A just continued fill order,, prevent from that A from can not receive to reply so the required time of reading order establishes fully longly.In this case, there is the too long shortcoming of equipment wait acknowledge time that transmits order.
