Description

Technical Field

[0001] This application relates to a control system for a metering box, in particular to an intelligent metering box remote control system. Background Art

[0002] With the continuous improvement of people's requirements for the quality of life, the demand for metering boxes is also increasing. Traditional metering boxes require on-site manual management, which is not only inefficient but also prone to errors. Therefore, it is of great significance to study an intelligent system for remotely controlling metering boxes.

[0003] Moreover, traditional metering boxes can only be controlled by one control terminal, unable to fully share information. And when there are matters that require assistance, currently, it can only be through other means such as phone calls to seek help from colleagues, etc. At the same time, in the remote control of metering boxes, there are also large errors in current sampling, which is an urgent problem to be solved. If there are errors in current sampling, it will lead to the inability to judge the actual situation during remote control, resulting in incorrect control instructions and further expanding the impact. Summary of the Invention

[0004] Based on this, it is necessary to provide an intelligent metering box remote control system for at least one of the above technical defects, so as to effectively improve the efficiency, safety and reliability of remote control of metering boxes.

[0005] An intelligent metering box remote control system includes:

[0006] A data acquisition module, a communication module, a server, a remote control terminal, and an assistance control terminal;

[0007] Among them, the data acquisition module is responsible for collecting data of the metering box. The communication module is used to transmit the collected data to the server and receive instructions from the remote control terminal. The server processes and stores the data, and feeds back the required data to the remote control terminal;

[0008] The remote control terminal sends control instructions to the metering box through the communication module to control the operation of the metering box;

[0009] The remote control terminal sends an assistance control request to the server. The server determines whether the assistance control terminal ID carried in the assistance control request is stored. If not, the assistance control terminal ID carried in the assistance request is added to the control terminal list for storage;

[0010] The server receives the control request sent by the assistance control terminal, determines whether the ID corresponding to the assistance control terminal sending the control request is in the control list. If so, it receives the control instruction sent by the assistance control terminal and forwards the control instruction to the metering box to remotely control the metering box.

[0011] In one embodiment, the data acquisition module includes a first current acquisition circuit, a second current acquisition circuit, and a current operation circuit. The first current acquisition circuit is connected in parallel on both sides of the resistor R1 for acquiring a first current , and the second acquisition circuit is connected in parallel on both sides of the resistor R2 for acquiring a second current , and the first current and the second current are jointly input into the current operation circuit to obtain an average value, thereby obtaining the final sampled current .

[0012] In one embodiment, one end of the resistor R1 is connected to the source electrode of the field effect transistor SW1, the drain electrode of the field effect transistor SW1 is connected to the drain electrode of the field effect transistor SW3, and the source electrode of the field effect transistor SW3 is connected to the other end of the resistor R1; one end of the resistor R2 is connected to the source electrode of the field effect transistor SW2, the drain electrode of the field effect transistor SW2 is connected to the drain electrode of the field effect transistor SW6, and the other end of the R2 is connected to the source electrode of the field effect transistor SW6; the source electrode of the field effect transistor SW3 is connected to the source electrode of the field effect transistor SW6 through an inductor L, and both ends of the inductor L are grounded through the field effect transistor SW4 and the field effect transistor SW5 respectively.

[0013] In one embodiment, after the server finishes forwarding the control instruction, it sends an execution result to the remote control terminal.

[0014] In one embodiment, the remote control terminal supports simultaneous login of multiple users, and different users can view the running status and data reports of different metering boxes.

[0015] In one embodiment, the communication module uses a half-duplex communication circuit, and the sending end and the receiving end are connected.

[0016] In one embodiment, the information between the remote control terminal and the server includes the following two parts: a message protocol for allocating remote control terminal parameters, and a start-stop message protocol for the remote control terminal.

[0017] In one embodiment, the server regularly sends the stored list of assisted control terminals and corresponding IDs to the remote control terminal.

[0018] For the above-mentioned intelligent metering box remote control system, the remote control terminal sends an assisted control request to the server. The server determines whether the assisted control terminal ID carried in the assisted control request is stored. If not, the assisted control terminal ID carried in the assisted request is added to the control terminal list for storage; and

[0019] The server receives the control request sent by the assisting control terminal, determines whether the ID corresponding to the assisting control terminal that sends the control request exists in the control list. If so, it receives the control instruction sent by the assisting control terminal and forwards the control instruction to the metering box to remotely control the metering box. By adding the assisting control terminal and maintaining a list of assisting control terminals in the server, when it is necessary to authorize or transfer the control authority, the efficiency of remote control is greatly improved. And when there are matters that require urgent handling in the analysis of the collected data and information synchronization is required, it can be quickly synchronized and reported upwards through the above method, and the processing decision of the urgent matter can be obtained faster, effectively improving the efficiency, safety and reliability of the remote control of the metering box. And through the design of the current acquisition circuit, the accuracy of data acquisition is effectively improved, avoiding increasing the difficulty of remote control due to the accuracy problem of data acquisition.

The character " / " generally means that the related objects before and after are in an "or" relationship.

[0025] Refer to Figure 1 as shown Figure 1 is a schematic diagram of an example of the remote control system for the intelligent metering box, as Figure 1 in, the remote control system for the intelligent metering box includes:

[0026] A data acquisition module, a communication module, a server, a remote control terminal, and an assistance control terminal;

[0027] Among them, the data acquisition module is responsible for acquiring data of the metering box, the communication module is used to transmit the acquired data to the server and receive instructions from the remote control terminal, the server processes and stores the data, and feeds back the required data to the remote control terminal;

[0028] The remote control terminal sends control instructions to the metering box through the communication module to control the operation of the metering box;

[0029] The remote control terminal sends an assistance control request to the server. The server determines whether the assistance control terminal ID carried in the assistance control request is stored. If not, the assistance control terminal ID carried in the assistance request is added to the control terminal list for storage;

[0030] The server receives a control request sent by the assistance control terminal, determines whether the ID corresponding to the assistance control terminal sending the control request is in the control list. If so, it receives the control instruction sent by the assistance control terminal and forwards the control instruction to the metering box to remotely control the metering box.

[0031] The solution of the above embodiment, by adding an assistance control terminal and maintaining a list of assistance control terminals in the server, greatly improves the efficiency of remote control when the control authority needs to be authorized or transferred, and when information synchronization is required for urgent matters in the analysis of the collected data, it can be quickly synchronized and reported upwards through the above method, and the processing decision of urgent matters can be obtained faster, effectively improving the efficiency, safety and reliability of remote control of the metering box.

[0032] Reference Figure 2 As shown, as an embodiment, Figure 2 is a schematic diagram of the composition of the data acquisition module of the present application. As Figure 2 shown, the data acquisition module includes a first sampling module 11, a second sampling module 12, and a current operation circuit 20. The first sampling module 11 includes a first current acquisition circuit 110; the second sampling module 12 includes a second current acquisition circuit 120. The first current acquisition circuit 110 is connected in parallel on both sides of the resistor R1 to collect the first current , the second current acquisition circuit 120 is connected in parallel on both sides of the resistor R2 to collect the second current , the first current and the second current are jointly connected to the current operation circuit 20 to obtain an average value to obtain the final sampled current .

[0033] One end of resistor R1 is connected to the source of field effect transistor SW1, and the connection point is A; the drain of field effect transistor SW1 is connected to the drain of field effect transistor SW3, and the source of field effect transistor SW3 is connected to the other end of resistor R1; one end of resistor R2 is connected to the source of field effect transistor SW2, and the connection point is B; the drain of field effect transistor SW2 is connected to the drain of field effect transistor SW6, and the other end of resistor R2 is connected to the source of field effect transistor SW6; the sources of field effect transistors SW3 and SW6 are connected through inductor L, and both ends of inductor L are grounded through field effect transistor SW4 and field effect transistor SW5 respectively. The drain of SW3 is used to receive input voltage Vin, and the drain of SW6 is used to output the output voltage of the circuit ; is the output current.

[0034] In the above embodiment, by designing the current acquisition circuit as above, the acquisition of current in a certain time period can be realized, and the acquisition of current is carried out after the field effect transistor has been continuously conducting for a period of time, thus avoiding the current peak suddenly generated at the moment when the field effect transistor suddenly conducts, which causes data error in current acquisition, thereby improving the accuracy of data acquisition.

[0035] As an embodiment, after the server completes the forwarding of the control instruction, it sends the execution result to the remote control terminal.

[0036] Sending the execution result to the remote control terminal can enable the remote control terminal to timely know the situation of the assisted control terminal being authorized to process, including whether the authorization is successful, and the final situation processed through the assisted control terminal, which is convenient for timely adjusting the processing strategy.

[0037] Reference Figure 3 shown, as an embodiment Figure 3 is a schematic diagram of the composition of the communication module of the present application. As shown in Figure 3 , the communication module uses a half-duplex communication circuit, and the sending end and the receiving end are connected.

[0038] In the above embodiment, the communication module includes a total of 8 ports, as shown in Ports 1-8 in the appendix Figure 3 . Among them, the sending end 3 and the receiving end 2 are connected and share one port. By controlling the high and low levels, it is determined whether the connected port is used as the sending end or the receiving end; port 8 is connected to the voltage, usually selected as 5V, ports 6 and 7 are used as shielded twisted pairs, and port 5 is grounded. TXD is the sending end, RXD is the receiving end, and VCC is the input voltage. This communication circuit can not only only require one access / output port to be configured, but also can correspondingly solve the problem of poor received signal caused by signal reflection.

[0039] As an example, the information between the remote control terminal and the server includes the following two parts: the message protocol for allocating remote control terminal parameters and the start / stop message protocol of the remote control terminal. This can further improve communication and achieve sufficient control exchange.

[0040] As an example, the server regularly sends the list of assisting control terminals and their corresponding IDs stored to the remote control terminal, so that the remote control terminal can regularly know the current number of assisting control terminals and the specific controlled situation, facilitating the corresponding holder to confirm whether to delete some IDs to revoke their control permissions. For example, when some employees leave the company, they do not want their original IDs to continue to be used as assisting control terminals.
