Description

Technical Field

[0002] At present, most of the control cabinets for sewage pumps are designed and manufactured based on the "proximity principle", and the control cabinets are set up near the pumps. For some pumps that need to be remotely controlled, long-distance wiring work is required. For buildings with complex architectural structures, such wiring construction is very time-consuming and material-consuming, and some dirt is corrosive to cables. In addition, since the subject matter involved in the control system belongs to the category of dirt, there are explicit pollution, such as odor, corrosion, etc.; implicit pollution, such as toxicity, radiation, etc., nearby operation will inevitably cause physical harm to the operator.

[0021] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0022] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figure 1 to Figure 2 As shown, the novel wireless controlled sewage system comprises a water pump 1, a terminal signal receiving device 2, a remote triggering device 3, a remote signal sending device 4 and a local control box 5, and the remote signal sending device 4 and the terminal signal receiving device 2 are electrically connected.

[0025] A wireless signal receiving device is set in the sewage cabinet, and a wireless signal sending device is set at the remote end (control center). The sending device is responsible for issuing operation commands, and the receiving device is responsible for receiving commands and driving the execution device to control the actions of the terminal equipment. The water pump can be remotely controlled without connecting through lines, which solves the problem of realizing the control function of the water pump without wiring in complex and harsh environments.

[0026] The remote trigger device 3 is provided with a signal sending circuit and a secondary control loop. The signal sending circuit includes a power supply DC12V, a remote signal sending device 4 and a trigger SB1. When the trigger SB1 is actuated and connected to generate a trigger signal, the signal is sent out by the signal transmitter in the form of a 398-525Hz band wireless signal, and the receiving device within a range of 5000m can receive the signal.

[0027] The local control box 5 is provided with a terminal water pump control circuit, a wireless signal receiving circuit and a secondary control circuit. The wireless signal receiving circuit includes a power supply DC12V and a terminal signal receiving device 2.

[0028] The water pump main circuit includes water pumps M1, M2, circuit breakers QF1, QF2, contactors 1KM, 2KM, thermal relays 1FR, 2FR.

[0029] The secondary control loop includes a control switch SAC1, a trigger SB2 (normally closed), a trigger SB3 (normally open), a control switch SAC2, and float switches FG1, FG2, FG3, and FG4.

[0030] The secondary control loop includes a manual control loop and an automatic control loop, and the operating mode is selected by the control switch SAC1.

[0031] The water pumps M1 and M2, one of which is a main pump and the other is a standby pump, are selected by a control switch SAC2.

[0032] When running in automatic mode, the start and stop of the water pump can be controlled by the float and the wireless signal receiving device. The wireless signal receiving device consists of a DC12V power supply and a wireless signal receiver. When the wireless signal is received, the wireless signal receiver converts the signal into a digital signal. Ports 8 and 4 are connected to ports 8 and 4 of the control loop, and the remote wireless start and stop of the water pump can be realized in combination with the source control circuit, which greatly improves the flexibility and convenience of equipment control.

[0033] The novel wireless controlled sewage discharge system of the present invention can control the terminal water pump control circuit through the host within a range of 5000. The slave sends a corresponding start-stop wireless signal through a low-voltage control trigger signal through auxiliary on-off devices such as knobs, buttons, switches, and emergency stops. The wireless signal is transmitted to the host through a band within a certain frequency range within the effective transmission range. After receiving the signal, the host converts it into a digital output to realize control of the control circuit, and then controls the water pump. Remote control and local control do not conflict with each other, and can be staggered control without priority.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
