The control device of the laboratory waste liquid collecting device is in wireless communication connection with the server or the mobile terminal.

When the user need empty the waste liquid, can adopt mobile terminal (cell-phone) to scan two-dimensional code on the laboratory waste liquid collection device, then log in on APP through modes such as face identification, thereby obtain the user authority of using laboratory waste liquid collection device, mobile terminal constitutes data interaction with the server simultaneously, with the record user login state, and download user experiment content data, can learn through experiment content data that the waste liquid that the user current experiment probably appears has which, and give laboratory waste liquid collection device with data synchronization, if the current collection container of laboratory waste liquid collection device does not satisfy the waste liquid collection demand (for example capacity is full or the waste liquid can not be compatible etc.), then in time inform the user.

As a preferable scheme, the laboratory waste liquid collecting device may not directly form data interaction with the server, but form a near field communication connection, such as a bluetooth connection, with the laboratory waste liquid collecting device, and then transmit the server data to the laboratory waste liquid collecting device via the mobile terminal device as a relay. For example, the user login authority data is sent to the server, the server feeds back the electronic key, and the mobile terminal receives the electronic key and then transmits the electronic key to the laboratory waste liquid collecting device through the Bluetooth. This benefit can reduce laboratory waste liquid collection device communication capacity demand, improves its reliability.

After the user obtains the authority, the type and volume data of the waste liquid are input through the mobile terminal and then transmitted to the server.

The server judges whether the laboratory waste liquid collecting device can realize current waste liquid collection according to the type and volume data historical data of the waste liquid, if so, judges which collecting container should be used, and whether the waste liquid which can be stored together can be determined by the principles of chemical reaction of chemical substances and the like generally, and an artificial neural network can be arranged in the server for judgment, and as the most strict scheme, one collecting container can only collect one type of waste liquid. After the server calculates the collection container to be used, the data is transmitted (directly or indirectly) to a control device of the laboratory waste liquid collection device, the control device controls a main driving motor to rotate, the selected collection container is aligned to the sliding guide pipe, and the control device reads a position signal of the turntable position detection device and judges whether the designated collection container is in place. If the designated collecting container is in place, the control device controls the electromagnet of the driving device to be electrified so as to enable the sliding guide pipe to descend to insert the end part of the sliding guide pipe into the designated collecting container, as a preferred scheme, a position switch can be arranged to feed back the position of the sliding guide pipe, if the sliding guide pipe slides in place, the control device controls the flip motor to open the controllable flip to be opened, then data is transmitted to the mobile terminal so that the mobile terminal prompts a user to pour designated waste liquid, the control device keeps the state of each device during the period, collects signals or data of a weight detection device of the designated collecting container, judges whether the weight increase reaches the preset value or not, after knowing the type and volume data of the waste liquid, the server converts the weight data of the waste liquid, and when the weight increase detected by the weight detection device meets the designated percentage of the weight data of the waste liquid, such as 98%, the control device inquires whether the user finishes pouring or not through interaction with the mobile terminal, if the user sends a pouring finishing instruction through input or voice, the control device controls the flip motor to rotate the controllable sealing cover to close the pouring opening, if the user does not respond, but when the weight increment detected by the weight detection device meets the specified percentage of the weight data of the waste liquid, such as 110%, the control device gives an alarm instruction to the mobile terminal, judges whether the weight data is interrupted by a slope value or not, and if so, gives an alarm to the server to call a manager, so that the user can be basically judged to begin to pour other waste liquids after pouring the specified waste liquid.

If the user normally sends through mobile terminal and emptys the instruction that finishes, controlling means control scavenging pump work, washes to holding the washing liquid funnel etc. and adopt the washing liquid to wash, when washing the completion back, controlling means control electro-magnet outage demagnetization to make the slip guide reset. One pour collection and cleaning was completed. The water yield can be controlled by the working time of the cleaning pump, and the injection amount of the inclined liquid can be fed back by the weight detection device. And uploading relevant information of the work, such as the type and weight of the waste liquid, the number of the collection container and the like to a service so as to realize tracing of the waste liquid.

After the laboratory waste liquid collection device finishes collecting, can concentrate waste liquid treatment center and handle.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
