}
2.4 control logic modification of functional Specifications
If the existing automatic control function is not satisfactory and needs to be modified, a program needs to be opened by using software VS code in the raspberry dispatching system, the program is modified in a main program app.js, the program is saved after the modification, and the system is restarted.
The software adopted by the system provides a file configuration function so as to improve the flexibility and the expansibility of the system. Including site parameter configuration, operation parameter configuration, and extension module configuration (see fig. 4). The above parameter configuration needs to modify the configuration file manually, and the configuration file can be changed according to actual requirements. Note that the system needs to be saved and restarted after the modification.
The external module and the system are connected by adopting a 485 bus. The system can be Windows or Linux and is connected with the module through a USB-to-serial port. Different serial paths need to be set when different systems are selected. The serial port setting function block is as follows:
function name: client. connected RTU ()
According to the information after the module configuration, after the module is connected to the bus, the system can read the state of the module according to the configuration information and start and stop the module output according to the program requirement. The control flow is shown in FIG. 5:
the functions needed to be used by the control module 3 program output in fig. 5 are divided into two types:
(1) switch Relay (index, t, callback) using 485 bus communication mode;
(2) open (), which directly drives hardware output;
the Gpio.open () function in the system is only packaged as a software module for standby. The scan read module of fig. 5 is illustrated in detail in the data acquisition module.
Function name: switchRelay (index, t, callback)
| Function(s) | Control module 3 output |
| Prototype | Is free of |
| Parameter name | Initial value |
| index | 0 |
| t | false |
| Return to | callback |
The actuating mechanism 4:
the executing mechanism 4 works in the sewage station and the data acquisition module 1 acquires relevant data, the executing mechanism 4 is motor equipment of the sewage station, the motor equipment data reflects the current equipment running state, and the control system judges faults according to the state; and the environment temperature T monitors the temperature and controls the start and stop of the cooling fan.
Substation client 5:
the sub-site client 5 establishes a communication relationship with the server platform interface 6 through a TCP/IP protocol. The sub-site client 5 is constructed by taking a raspberry as a control core and through a raspberry embedded system, the sub-site client 5 and the MCU control unit 2 form data conversion, the converted data is connected to the server platform interface 6, and then the remote control terminal 7 is controlled.
Server platform interface 6: the server platform interface 6 is electrically connected with the remote control terminal 7 for remote monitoring
The interface mainly refers to an interface of software, and the Client terminal provides an interface name. And continuously receiving the instruction from the Server end in the process of communicating with the Server end. The instructions are directly used as interface objects and provide upper software access for control.
The Client monitors the command data sent by the Server (receives the interface data), then continuously analyzes the data, and judges the interface attribute and controls (writes data and captures data) after analyzing the data (as shown in fig. 8).
Description of communication function of the substation client 5 and the server platform interface 6:
after the data conversion, the data needs to be sent to the server. The system communication adopts Socket and server connection. The Client communication establishing process firstly establishes a monitoring port number and a server IP and then monitors data. In addition, in order to improve the fault recovery capability and fault tolerance rate of the system, the received packet data needs to be detected, and once the failure that the data cannot be received within a certain time is found, the data should be reported and response is made.
Here, a socket is an eventemiter (i.e., the core module of the programming software itself, which is an asynchronous driver framework). It may trigger "connect", "end", "timeout", "drain", "close" events. Thus, it is natural to have "error" as another event that can be triggered.
Therefore, the communication mechanism required by us can be established according to the driving framework. The specific communication flow is shown in fig. 7:
the communication functions used were tcpclient.connect (serverPort, serverp, function () { }) and tcpclient.on. The method is mainly used for setting network parameters and connecting.
Function name: tcpclient. connect (serverPort, serverp, function () { })

| Function(s) | Network connection |
| Prototype | net.Socket() |
| Parameter name | Initial value |
| string | Is free of |
| function() | Is free of |
| Return to | Callback function () |
The remote control terminal 7:
the control of the actuating mechanism 4 can be realized through remote data communication, for example, the motor equipment data reflects the current equipment running state, and the control system judges the fault according to the state; and the environment temperature T monitors the temperature and controls the start and stop of the cooling fan. Such as a display screen, a computer or a smart phone.
Sewage station:
the sewage station is provided with sewage treatment equipment and monitoring equipment so as to implement operation.
The operation principle process of the system is as follows:
because the actuating mechanism 4 and the sewage station equipment are electrically connected with the data acquisition module 1, the data acquisition module 1 acquires sewage quality data and equipment operation data of the sewage station and is connected to the MCU control unit 2 through a 485 bus; the related data reaching the MCU control unit 2 enters the sub-site client 5 through data conversion, and real-time monitoring can be realized because the sub-site client 5 and the server platform interface 6 are in two-way communication by using TCP/IP (transmission control protocol/Internet protocol), and the server platform interface 6 and the remote control terminal 7 are also in two-way communication. The data command sent by the remote control terminal 7 reaches the substation client 5 through the server platform interface 6 (reserved interface for facilitating the access of a third party monitoring platform), enters the MCU control unit 2 through data conversion, and then is sent to the execution mechanism 4 by the control module 3 to complete the operation of the corresponding command.
