[0020] The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0021] Since the short-circuit port pressure drop detection in the prior art is mostly detected manually by using a pressure drop detector, it does not meet the requirements of accuracy, continuity and real-time. Therefore, the present application aims to provide a short-circuit port pressure drop remote monitoring device for an electrolytic cell, which can remotely monitor the pressure drop of the short-circuit port of the electrolytic cell, and effectively improve the accuracy, continuity and real-time of the pressure drop data monitoring.

[0022] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0023] As shown in Figure 1 The short-circuit port pressure drop remote monitoring device for an electrolytic cell disclosed by the present application comprises two parts: a field pressure drop collection device and a remote receiving and analyzing device.

[0024] The field pressure drop collection device of the present application comprises N pressure drop detectors, N standard signal transmitters and N 4G signal transmitters matched with the pressure drop detectors, in addition, the field pressure drop collection device of the present application is further provided with an over-limit sound-light alarm and a first power module.

[0025] Specifically, a pressure drop detector is arranged at each short-circuiting port of the electrolytic cell. A standard signal transmitter is connected in parallel with the pressure drop detector, both of which are used to collect the pressure drop signal of the short-circuiting port of the electrolytic cell. In addition, the pressure drop detector is also used to display the pressure drop signal in real time, and the standard signal transmitter is also used to convert the pressure drop signal into a standard signal. The 4G signal transmitter is electrically connected with the standard signal transmitter, and is used to receive the standard signal output by the standard signal transmitter and transmit the standard signal point-to-point through a 4G network. The ultralimit sound-light alarm is electrically connected with the N pressure drop detectors, and the ultralimit sound-light alarm performs real-time sound-light alarm according to the pressure drop signal collected by the pressure drop detector. The first power module is a 12V DC battery, which is electrically connected with the pressure drop detector, the standard signal transmitter, the 4G signal transmitter and the ultralimit sound-light alarm.

[0026] As a specific embodiment, the pressure drop detector of the present application is powered by a low-voltage lithium battery (first power module). Generally, the dry environment outside is below 36V, which is a safe voltage. The present application uses a 12V DC battery to power each part of the on-site pressure drop collection device. The pressure drop detector is installed at each pressure drop detection point of the short-circuiting port of the electrolytic cell to collect the pressure drop data of a single short-circuiting port and obtain the pressure drop signal at each short-circuiting port. Generally, a single electrolytic cell has a total of 6 short-circuiting ports. Therefore, as a specific embodiment, the present application arranges 6 pressure drop detectors, and displays the pressure drop data in real time on site through the pressure drop detector.

[0027] The pressure drop detector also has an ultralimit output node. After the pressure drop detector has set the alarm upper limit, the pressure drop detector compares the collected pressure drop data with the set alarm upper limit. When the collected pressure drop data is greater than or equal to the alarm upper limit, the pressure drop detector outputs an alarm signal to the ultralimit sound-light alarm on site. The ultralimit sound-light alarm is used in conjunction with the pressure drop detector, is electrically connected with the pressure drop detector, and inputs the alarm signal output by the pressure drop detector to emit sound-light alarm in real time.

[0028] The standard signal transmitter is used in conjunction with the pressure drop detector. The standard signal transmitter and the pressure drop detector are connected in parallel to collect the voltage signal at the pressure drop detection point of the short-circuiting port as the pressure drop signal. In addition, the standard signal transmitter is also used to convert the pressure drop signal into a 4-20mA current signal as a standard signal.

[0029] The 4G signal transmitter is also used in conjunction with the pressure drop detector. The 4G signal transmitter is electrically connected with the standard signal transmitter, receives the 4-20mA standard signal output by the standard signal transmitter, and transmits the 4-20mA standard signal point-to-point to the 4G signal receiver through a 4G network.

[0030] The remote receiving and analyzing device comprises a multi-channel patrol instrument, N 4G signal receivers corresponding to N 4G signal transmitters, a 485 protocol converter and a second power module.

[0031] Specifically, the N 4G signal receivers are electrically connected with the multi-channel patrol instrument. The 4G signal receivers are installed in a control room and are used to receive standard signals transmitted by the 4G signal transmitters and transmit the standard signals to the multi-channel patrol instrument, and the multi-channel patrol instrument is used to convert the standard signals into pressure drop signals in real time.

The 485 protocol converter is used to receive the pressure drop signals output by the multi-channel patrol instrument and convert the pressure drop signals into Ethernet signals and transmit the Ethernet signals to an industrial Ethernet. The second power module is a 220V AC battery and is electrically connected with the multi-channel patrol instrument, the 4G signal receivers and the 485 protocol converter.

[0032] As a specific embodiment, the 4G signal receivers are installed in the control room, are powered by 220V AC batteries and are used to receive signals transmitted by the 4G signal transmitters and output standard signals.

[0033] The multi-channel patrol instrument is installed in the control room, is powered by 220V AC batteries and is used to receive standard signals transmitted by six short-circuit ports through 4G networks, convert the standard signals into short-circuit port pressure drop data in real time and has the functions of data recording, data exporting, curve generation and alarming.
