Detailed Description
The invention provides a water quality monitoring method and water quality monitoring equipment, aiming at solving the technical problem that a method or equipment capable of realizing remote water quality monitoring is lacked in the prior art.
Example 1:
in this embodiment, a water quality monitoring method is provided.
Referring to fig. 1, a water quality monitoring method includes:
s01, obtaining the long connection state of local and remote networks;
s02, receiving detection data;
s03, locally storing the detection data;
and S04, transmitting the detection data in case that the long connection status of the local and remote networks is 'yes'.
In one application scenario of this embodiment, the detection data needs to be received locally, and the detection data needs to be sent to a remote water quality monitoring device, or a cloud platform, or a handheld APP, or a wechat applet, or the like. That is, after receiving the detection data locally, the detection data may be stored locally, or the detection data may be sent out through the network.
Because the security importance of water resources is high, it is desirable to maintain a smooth network connection. The long connection state of the local network and the remote network is adopted, so that the detection data can be sent out in time according to the preset conditions under the condition that the network is smooth.
In the prior art, the method for monitoring the water quality usually adopts manual detection, or adopts a few devices to detect on the water resource site; that is, the prior art methods for monitoring water quality all require a lot of manual work to perform on-site detection on water resource sites, thereby increasing the cost of detecting water quality.
In the embodiment, the detection data collected locally (on the water resource site) is sent out through the network, so that the effect of remote monitoring is achieved. That is to say, the water quality monitoring method provided by the embodiment solves the technical problem that a method or equipment capable of realizing remote water quality monitoring is lacked in the prior art.
In the present embodiment, the long connection status of the local and remote networks is a necessary condition for sending out the detection data, however, the long connection status of the network may also cause an interruption due to unexpected reasons (such as power failure, signal interference or low signal strength). Therefore, how to manage the detection data in the case of a possible interruption of the long connection state of the network is preferably implemented by the following method steps.
Referring to fig. 2, S100, a long connection status of a local network and a remote network is detected in real time;
referring to fig. 2, S101, if the local and remote network long connection status changes from yes to no, generating a network exception event, and storing the network exception event locally;
referring to fig. 3, S102, if the long connection status of the local and remote networks changes from 'no' to 'yes', sending the locally stored detection data to the remote;
referring to fig. 4, in S103, if the local and remote network long connection states are changed from 'no' to 'yes', waiting for receiving a read instruction, and after the network abnormal event is read by the read instruction, clearing the network abnormal event stored in the local, where the read instruction is a local read instruction or a remote read instruction, and if the read instruction is a remote read instruction, sending the network abnormal event to the remote;
referring to fig. 5, S104, if the local and remote network long connection states are yes or no, transmitting a first instruction for turning on the water pump according to a preset time node;
referring to fig. 6, in case that the local and remote network long connection states are 'yes', a heartbeat packet is transmitted to the remote, S105.
In step S101, the network long connection state is changed from yes to no, which indicates that the communication between the local and remote devices is interrupted, generates a network abnormal event, and stores the network abnormal event locally. At this time, the request message should be issued locally until after the remote response, and the network long connection state is reestablished locally and remotely. In the embodiment, the network long connection state is realized through a TCP protocol.
In step S102, if the local and remote network long connection status is changed from 'no' to 'yes', it indicates that the local and remote network long connection status has been restored; at this time, the network abnormal event should be sent from local to remote, which is beneficial to remotely 'record' the local network abnormal event. Under the arrangement, remote intelligent maintenance and diagnosis can be conveniently and remotely carried out on site; namely, the reason of network interruption between the local area and the remote area can be judged remotely through the network abnormal event, so that the staff is guided or reminded to carry out corresponding overhaul.
In step S103, if the local and remote network long connection status is changed from 'no' to 'yes', it indicates that the local and remote network long connection status has been restored; at this time, a read command issued from the outside may be received locally for reading the network exception event. The read command sent from the outside may be a read command sent locally and received locally, or a read command sent remotely and received locally. After the reading instruction is locally received, reading the network abnormal event according to the preset condition, so that the 'network fault' occurring locally is 'read' by the worker, and the worker can conveniently maintain and overhaul the local equipment or system; the ' network fault ' occurring locally can be read ' by the remote device, and the network abnormal event should be sent to the remote locally, so that the remote device can perform remote intelligent maintenance diagnosis on the local locally. If the network exception event is read, the locally stored network exception event should be cleared, and the purpose of this step is to: under the condition of limited storage space, the former network abnormal event is cleared, thereby facilitating the storage of the latter network abnormal event.
In step S104, regardless of whether the local and remote network long connection states are 'yes' or 'no', a first instruction for turning on the water pump should be issued when the local device or system is started. In some special cases, for example: if the network long connection state is negative and the local equipment or system is started, a first instruction can be sent according to a preset time condition in order to better monitor the water quality safety of the water resource and obtain the detection data. For the convenience of those skilled in the art, the foregoing 'issuing the first instruction according to the preset time condition' may be understood as issuing the first instruction at regular time, but the 'issuing the first instruction according to the preset time condition' should not be limited to issuing the first instruction at regular time. By adopting the step 104, when local equipment or a local system is started under the condition that the long-distance network connection state between the local and the remote is interrupted, water quality detection can still be carried out on water resources, and detection data can be obtained; after the long connection state of the local and remote networks is recovered, the detection data stored in the local can be sent to the remote, so that the remote server can continue to analyze the detection data.
In step S105, a heartbeat packet mode is adopted, and information is sent from the local to the remote according to the preset duration of the heartbeat packet; that is, if the local is considered as a client and the remote is considered as a server, then the client should send a packet to the server every short time, the server is 'notified' by the client that the client is online anyway.
In this embodiment, one situation that may occur is: if the local and remote network connection status is interrupted for a long time, the local storage space is eventually filled up by the network abnormal event. To solve this problem, the following steps are preferably employed.
If the long connection state of the local and remote networks is changed from ' yes ' to ' no ', generating a network abnormal event, and locally storing the network abnormal event ' further comprises:
referring to fig. 2, in S106, if the storage space for storing the network exception is insufficient, the subsequent network exception is overwritten with the previous network exception.
After the local storage space is occupied by the previous network abnormal event, the storage space is insufficient, and the previous network abnormal event can be covered by the subsequent network abnormal event. By adopting the mode, the problem that if the local and remote network connection states are interrupted for a long time, the local storage space is filled with the network abnormal event can be obviously and effectively solved.
In this embodiment, in order to solve the problem of local system time deviation, the following steps are preferably adopted.
Referring to fig. 7, S201 waits for receiving a timing instruction;
referring to fig. 7, S202, the local time parameter is corrected according to the timing instruction.
That is, the local system should modify the local time parameter according to the remote timing command, in order for the local system time to coincide with the time of the remote server.
In this embodiment, in order to solve the problem of local remote system upgrade, the following steps are preferably adopted.
Referring to fig. 8, S203, waits for receiving an upgrade package;
referring to fig. 8, S204, local update is performed according to the upgrade package.
That is, if the remote server has generated the upgrade package, the local server should be able to receive the upgrade package through the network and perform the upgrade of the local system according to the received upgrade package. The specific manner of acquiring the upgrade package may be implemented by a manner in the prior art, for example, a manner of acquiring the upgrade package by a smart phone, which is not described herein again.
In this embodiment, the detection standard of water quality is changing, for example: the national standard of water quality detection changes, the local standard of water quality detection changes, the standard of water quality detection of industrial water or agricultural water changes, and the like, so that local equipment or system should update the setting parameters in time. In order to solve the problem of how to update the setting parameters, the following steps are preferably adopted.
Referring to fig. 9, S205 waits for receiving a setting parameter, where the setting parameter is a remote setting parameter or a local setting parameter;
referring to fig. 9, S206, the setting parameters are stored locally.
The setting parameters received locally may be the setting parameters sent locally and received locally, or the setting parameters sent remotely and received locally. After receiving the setting parameters locally, the setting parameters may be stored locally, so that a worker or a remote server may obtain actual setting parameters.
In order to facilitate the local setting parameters to be obtained by the remote server, the following steps are preferably adopted.
The method comprises the following steps of waiting for receiving setting parameters, wherein the setting parameters are remote setting parameters or local setting parameters, and the step of storing the setting parameters locally further comprises the following steps:
referring to fig. 9, S206, in case that the setting parameter is a local setting parameter and the local parameter is changed, the local setting parameter is transmitted.
That is, under the condition that the local setting parameters are modified and are limited to the local modification, the modified setting parameters that have been stored locally should be sent to the remote server side through the network, so that the local setting parameters and the remote setting parameters are consistent.
In this embodiment, in order to avoid the modification of the setting parameters by local non-working personnel, the following steps are preferably adopted.
Referring to fig. 10, in step 'waiting for receiving the setting parameter, where the setting parameter is a remote setting parameter or a local setting parameter, before storing the setting parameter locally', the method further includes:
s301, judging whether a first authority is provided;
s302, if the device has the first authority, the device can receive local setting parameters;
s303, if the first authority is not provided, judging whether a second authority is provided, wherein the first authority is larger than the second authority;
s304, if the second authority is provided, the local setting parameters can be received;
wherein the second right specifically is: receiving password instructions according to preset times;
if one of the password instructions is the same as the preset password, the password instruction has a second authority;
otherwise, the receiving of the password instruction is suspended.
It will be appreciated by those skilled in the art that the first right may be an administrator right, and may be obtained by way of a local password or remote authorization; the second right may be a work right, which may be obtained by means of a local password or remote authorization, and the first right should be greater than the second right. However, those skilled in the art should not limit the first right to only administrator rights, nor should the second right be limited to only work rights.
Under the condition of having the first authority, the staff can locally modify the setting parameters; and under the condition of having the second authority, the staff can locally modify the setting parameters.
The second right preferably employs cryptographic rights, such as: the password is given to local staff, and the local system can be modified. Local staff obtains the second permission through the password, and not only can the setting parameters be modified, but also corresponding overhaul work can be carried out.
If the local system receives the password, but the received password does not accord with the preset password, an alarm can be sent out; in addition, in order to avoid receiving wrong passwords for multiple times, the preset times should be set, so that a worker with management authority or a remote server side is reminded.
