Description

Technical Field

[0001] This utility model belongs to the field of group control technology, and in particular relates to a matrix setting device for multi-batch group control under complex working conditions. Background Technology

[0002] Grouped control of multiple batches of equipment is a common working scenario across various industries and a common way to achieve automated and intelligent operation. Under a predetermined strategy, when control conditions occur, control actions are automatically completed to adapt to changes in external conditions, playing an important role in improving operational efficiency and controlling the spread of accidents. For example, in a regional power system, when power supply and load are mismatched, loads or power supplies need to be put into, taken out of, or adjusted in multiple batches according to a predetermined strategy under different operating conditions. Similarly, in smart city management and smart transportation management, lighting facilities need to be controlled or their brightness adjusted in batches when the brightness of the natural environment changes or reaches a certain time point. In smart park management, changes in the brightness and color of landscape lighting require batch control of lighting facilities. Furthermore, when a building catches fire, power needs to be cut off according to predetermined fire compartments.

[0003] Currently, the main method for implementing multi-batch group control of equipment under complex operating conditions is through computer monitoring, workflow settings, and software programming. While conventional relay methods are generally easy to implement single-batch control under single operating conditions, they are more difficult to implement for multi-batch control, and even more challenging for multi-batch control under complex operating conditions. Because the application of multi-batch group control under complex operating conditions involves numerous system devices, complex operating conditions, cumbersome operating strategies, and high integration, different projects and different technical personnel employ different technical approaches, generally adopting a one-engineer-one-design approach, which is time-consuming and labor-intensive. In project work, these traditional solutions often encounter the following problems:

[0004] (1) The standardization level is not high. Each project has to be redesigned and strictly checked, which has a high probability of error and takes a long time.

[0005] (2) Computer monitoring manufacturers must write programs according to the design drawings and processes, and each step must be strictly checked, which has a high probability of error and takes a long time.

[0006] (3) Installation and debugging are time-consuming. Each step of the process is carefully debugged, which increases the probability of errors and makes it difficult to detect problems.

[0007] (4) Modification and adjustment work is time-consuming and labor-intensive. When modifying or adjusting one part, the design unit has to redo the technical route and logical flow, the manufacturer has to modify the program, and the installation unit also has to modify the wiring and re-debug, which is time-consuming and labor-intensive.

[0008] (5) Poor flexibility; once the control strategy is set, the modification and adjustment process is cumbersome. When external conditions change, the strategy often needs to be adjusted, but operation and maintenance personnel cannot access the manufacturer's internal program to make modifications. The manufacturer needs to go to the site to modify and re-debug the system, and each modification requires a lot of manpower and time. Therefore, the adjustment is inflexible and it is difficult to cope with frequent changes. Summary of the Invention

[0024] Compared with the prior art, the present invention has the following outstanding advantages:

[0025] (1) It lowers the threshold for adjusting the control strategy. Traditional solutions require modifying the computer program every time the strategy is adjusted.

Ordinary operation and maintenance personnel can also complete the task, greatly improving convenience.

[0026] (2) High intuitiveness. Utilizing the matrix concept, control strategies are set, and operators can intuitively see the controlled batches on the panel and observe the entire process.

[0028] (4) The circuit is simple and highly standardized. The standardized design and packaged products avoid design omissions, have strong versatility, and do not require redesigning the circuit for each project.

[0029] (5) Simple production. It can be standardized and scaled up, improving production efficiency and reducing production costs.

[0030] (6) Easy to install and use. The packaged, pre-designed product can be directly installed and used. The whole unit is installed in a box (cabinet), and users can directly connect to the corresponding interface, which improves the convenience of use.

[0031] (7) Easy to install and debug. During installation and debugging, only the external interface of the device needs to be connected, and there is no need to check the internal circuit, which improves the efficiency of installation and debugging.

[0032] (8) Wide range of applications. It can be applied to projects with relevant needs in various industries, without obvious industry restrictions. Attached Figure Description

[0039] I. Basic Design

[0040] like Figures 1 to 6 As shown, the matrix setting device of this utility model for multi-batch group control under complex working conditions includes a power supply, a working condition input unit, a batch condition input unit, a matrix unit, an action output unit, a signal output unit, a metal housing, and its panel. Among them,

[0041] The matrix unit is a three-dimensional matrix composed of levels, horizontal axes, and vertical axes. Each working condition is a level, and several working conditions constitute several levels, which is one dimension. Each batch condition is a horizontal axis, which constitutes several horizontal axes, which is the second dimension. The positive terminals of the coil drive circuits of each relay constitute several vertical axes, and the negative terminals are connected to the negative terminals of the power supply, which constitute the third dimension.

[0042] Matrices can be represented in two ways: logical matrices and entity matrices.

[0043] A logic matrix logically implements the functions of a matrix, but it does not appear in the form of a matrix; it only appears as an electrical wiring diagram. In the logic matrix, the batch conditions constitute several logical horizontal axes; each relay coil drive circuit is equipped with a rotary switch. One end of each rotary switch is shorted to the relay coil drive circuit, forming several logical vertical axes, and the other end is connected to each horizontal axis. The rotary switches connect the corresponding horizontal and vertical axes to connect the corresponding condition input and action output circuits.

[0044] In the physical matrix, the horizontal and vertical axes are constructed using solid copper busbars (e.g., 5-10mm thick, 20-25mm wide, with length determined by the matrix size). The horizontal and vertical axes are supported by insulators at different heights, ensuring the horizontal axis lies on one plane and the vertical axis on another. The horizontal and vertical axes do not touch and have no electrical connection; they only intersect through projection. Corresponding circular screw holes are created at the intersection points of the horizontal and vertical axis projections. Copper screws can be passed through these holes to electrically connect the horizontal and vertical axes, linking the corresponding batch condition inputs and action output circuits, thus successfully setting the action strategy. Positions without screws indicate no electrical connection, meaning no control is enabled.

[0045] The operating condition input unit allows for manual setting of operating conditions via a rotary switch on the panel or via external commands. Several operating condition input interfaces are provided; these interfaces use normally open, normally closed, and holding contact signals, supplied externally. Only the holding contact signals for operating condition 1, operating condition 2… operating condition n need to be provided externally. Only one operating condition can be active at a time; multiple operating conditions cannot occur simultaneously.

[0046] In the batch condition input unit, several condition input interfaces for controlling batches are reserved. The condition input interface is a normally open, momentary dry contact signal. The signal is provided externally. The externally only needs to provide the dry contact signals for the first batch to be turned on, the second batch to be turned on, ... the nth batch to be turned on, and the first batch to be turned off, the second batch to be turned off, ... the nth batch to be turned off.

[0047] In the action output unit, the action output consists of the auxiliary contacts of each relay. Each relay corresponds to one controllable device. Each relay uses a pair of normally open normally closed contacts as the action output interface. When the relay is driven, the normally open contacts close and send control commands to the device.

[0048] The power circuit is equipped with conventional components such as circuit breakers and power monitoring relays to provide power and monitor the entire device.

[0049] Each circuit and relay is encapsulated within a robust metal casing with excellent electromagnetic shielding and heat dissipation. Various selector switches, rotary switches, and indicator lights are embedded in the panel, forming an independent device. Standardized and fixed external interfaces, including corresponding power input interfaces, primary circuit output interfaces, various control condition input interfaces, and signal output interfaces, are provided and arranged in a hard-wired manner at the rear of the device, forming a standardized product. Users can directly connect the corresponding interfaces according to their functional requirements.

[0050] The control panel is preferably made of insulating material, but metal can also be used. The panel is divided into two areas: a common area and a matrix area. The common area houses power indicator lights. The matrix area is for manual settings. The matrix area of ​​the physical matrix displays horizontal and vertical axis diagrams, and the holes on the panel correspond to the screw holes in the internal physical matrix. When setting control strategies on the panel, operators screw in screws to electrically connect the corresponding horizontal and vertical axes of the internal physical matrix. The logic matrix uses rotary switches on the panel to manually set operating conditions and the switching batches for each condition.

[0051] In the solid matrix, the screw head can adopt a stepped structure with two diameters, made of insulating material, and designed as a flat cylindrical checkerboard shape, black in color. The screw can be tightened manually without a screwdriver. The larger diameter portion of the stepped screw head is larger than the panel screw hole, allowing the screw head to adhere to the panel after tightening; the outer diameter of the smaller diameter portion fits the inner diameter of the panel screw hole, effectively isolating the panel and the screw, ensuring insulation. The screw diameter is smaller than the opening on the panel, and the smaller diameter portion of the screw head maintains isolation and insulation between the screw and the edge of the panel screw hole. The length can pass through the horizontal and vertical axes of the solid matrix inside the box. The thread matches the opening screw hole in the solid matrix inside the box. Panel holes without screws can be covered with caps. The caps have the same shape and material as the screw head but do not have screws; they are made of insulating material and are white in color, used to distinguish unspecified parts.

[0052] Since the device involves external contacts driving multiple relay coils, it is advisable to select low-power relays and control their number; or the total power of the relays should not exceed the opening capability of ordinary unused contacts.

[0053] The overall dimensions of the device are designed according to the dimensions of electrical devices in standard cabinets, which allows for easy installation in cabinets.
