Abstract

Methods, systems, and computer program products for wirelessly communicating with various system controllers of a facility through a wireless interface module. A mobile computing device may wirelessly connect with the wireless interface module to transmit information to and receive information from the wireless interface module. Specifically, a washing machine may be coupled to the system controller and may require various chemicals to perform the underlying washing tasks. As the chemicals are utilized, system controllers provide usage data and any other relevant data to the wireless machine interface, which may in turn provide the data to the mobile computing device upon request. Similarly, the mobile computing device may transmit system setting information, updated formulas, or other information to the wireless interface module for incorporation into one or more system controllers.

Claims

1. An interface module for coupling a controller for a chemical dispensing system to a network, the interface module comprising:

one or more processors; and

a memory coupled to the one or more processors and containing program code that, when executed by at least one of the one or more processors, causes the interface module to;

poll the controller for data relating to usage of a chemical product dispensed by the controller;

in response to receiving the data for a current polling period, parse the data;

determine a relative change between the parsed data for the current polling period and the parsed data for a last polling period;

determine an amount of the chemical product that was dispensed by the controller since the last polling period based on the relative change;

store the data in the memory; and

in response to receiving a request from a computing device, provide the data to the computing device.

2. The interface module of claim 1 wherein the program code causes the interface module to provide the data to the computing device by:

generating a webpage containing at least a portion of the data; and

causing the webpage to be displayed on the computing device.

3. The interface module of claim 2 wherein the data includes diagnostic information, connectivity status, current formulas being executed, sensor information, or power failure information for the controller.

4. The interface module of claim 1 wherein the computing device accesses the interface module remotely over the Internet.

5. The interface module of claim 1 wherein the program code further causes the interface module to:

determine a status of the chemical product based on the amount of the chemical product that was dispensed by the controller since the last polling period;

generate a webpage conveying the status of the chemical product; and

cause the webpage to be displayed on the computing device.

6. The interface module of claim 1, wherein the controller is one of a plurality of controllers for chemical dispensing systems, the chemical product is available to be dispensed by each controller of the plurality of controllers, and the program code further causes the interface module to:

poll each controller of the plurality of controllers for the data;

aggregate the amount of the chemical product that was dispensed by each of the controllers since the last polling period for the controller into a total amount of the chemical product;

determine whether the total amount of the chemical product is beyond a threshold value; and

in response to determining the total amount of the chemical product is beyond the threshold value, order an additional supply of the chemical product, alert an interested party, or both.

7. The interface module of claim 1 wherein the program code further causes the interface module to:

receive updated settings for the controller from the computing device; and

transmit the updated settings to the controller.

8. The system of claim 7 wherein the updated settings include an updated chemical formula to be dispensed by the controller.

9. A method of coupling a controller for a chemical dispensing system to a network using an interface module including a memory, the method comprising:

polling the controller for data that relates to usage of a chemical product dispensed by the controller;

in response to receiving the data for a current polling period, parsing the data;

determining a relative change between the parsed data for the current polling period and the parsed data for a last polling period;

determining an amount of the chemical product that was dispensed by the controller since the last polling period based on the relative change;

storing the data in the memory; and

in response to receiving a request from a computing device, providing the data to the computing device.

10. The method of claim 9 wherein providing the data to the computing device comprises:

generating a webpage containing at least a portion of the data; and

causing the webpage to be displayed on the computing device.

11. The method of claim 10 wherein the data includes diagnostic information, connectivity status, current formulas being executed, sensor information, or power failure information for the controller.

12. The method of claim 9 wherein the computing device accesses the interface module remotely over the Internet.

13. The method of claim 9 further comprising:

determining a status of the chemical product based on the amount of the chemical product that was dispensed by the controller since the last polling period;

generating a webpage conveying the status of the chemical product; and

causing the webpage to be displayed on the computing device.

14. The method of claim 9, wherein the controller is one of a plurality of controllers for chemical dispensing systems, the chemical product is available to be dispensed by each controller of the plurality of controllers, and further comprising:

polling each controller of the plurality of controllers for the data;

aggregating the amount of the chemical product that was dispensed by each of the controllers since the last polling period for the controller into a total amount of the chemical product;

determining whether the total amount of the chemical product is beyond a threshold value; and

in response to determining the total amount of the chemical product is beyond the threshold value, ordering an additional supply of the chemical product, alerting an interested party, or both.

15. The method of claim 9 further comprising:

receiving updated settings for the controller from the computing device; and

transmitting the updated settings to the controller.

16. A computer program product for coupling a controller for a chemical dispensing system to a network using an interface module including a memory, the computer program product comprising:

a non-transitory computer-readable storage medium; and

program code stored on the non-transitory computer-readable storage medium that, when executed by one or more processors, causes the interface module to;

poll the controller for data relating to usage of a chemical product dispensed by the controller;

in response to receiving the data for a current polling period, parse the data;

determine a relative change between the parsed data for the current polling period and the parsed data for a last polling period;

determine an amount of the chemical product that was dispensed by the controller since the last polling period based on the relative change;

store the data in the memory; and

in response to receiving a request from a computing device, provide the data to the computing device.
