Abstract

Disclosed in the invention is a bus controller of a hydrotherapy apparatus. The bus controller comprises a main control unit, N sub induction machines, and N execution units corresponding to the N sub induction machines. An input terminal of the main control unit is connected with a power supply; and a signal acquisition terminal of the main control unit is connected with the N sub induction machines by buses. The main control unit carries out communication with the N sub induction machines one by one by using a cyclic query way and collects the state of each sub induction machine; the N sub induction machines are connected to one group of buses and each N sub induction machine has a unique address identification code by corresponding to the bus; the main control unit distributes one execution unit correspondingly for the unique address identification code of each sub induction machine; and the execution units are formed by alternating-current contactors and hydrotherapy pumps. According to information of bathers, corresponding hydrotherapy pumps can be turned on in sequence; and with the bus control mode, all hydrotherapy pumps can work independently without any influence. On the basis of the bus control way, the signal transmission is stable.

Description

technical field

[0001] The invention relates to the technical field of bus control, in particular to a bus controller of hydrotherapy equipment. Background technique

[0002] The control methods of the commonly used spa equipment pumps are all in a one-to-one relationship, that is, one sensor sub-machine corresponds to one controller. The controller drives the water pump through the AC contactor. When the bather needs the spa function, touch the corresponding sensor sub-machine. The sensor sub-machine transmits the signal to the controller, and the controller starts the hydrotherapy pump corresponding to the sensor to realize the hydrotherapy function. The sensor sub-machine and the controller are connected one-to-one by wires. If there are many sensor sub-units, multiple sets of communication wires need to be laid, and the connection between the controller host and the sensor sub-units requires at least two to three wires. This requires a lot of wire. During engineerin...
